(2) The claims administrator or, if none, the employer and the unrepresented employee agree that a new panel may be issued in the geographic area of the employee's work place. (3) The Medical Director, upon written request, finds good cause that a replacement QME is appropriate for reasons related to the medical nature of the injury. For purposes of this subsection, "good cause" is defined as a documented medical or psychological impairment. (4) The Medical Director, upon written request, determines after a review of all appropriate records that the specialty chosen by the injured worker is medically or otherwise inappropriate for the injury to be evaluated. (5) Any violation of Section 34. (c) The Medical Director shall select replacement QME(s) at random. Note: Authority cited: Sections 139, 139.2, 4061 and 4062, Labor Code.

(a) For injuries occurring between January 1, 1991 and December 31, 1993, a party may request the Medical Director to direct the QME to consult with a physician in an appropriate specialty to address issues outside the QME's specialty if the party believes such a consultation is necessary to provide a complete and accurate examination pursuant to section 4061 of the Labor Code. The party requesting the consultation shall specify in writing the reasons for the consultation. Valid reasons for providing the QME consultation shall include, but not be limited to, the expertise of the QME, the accuracy of the QME comprehensive medical-legal evaluation in question and the complexity of the medical issue involved. (b) The Medical Director shall appoint a separate list of physicians for requests pursuant to subsection (a), and shall, in his or her discretion, grant or deny the request within 30 days. (c) For injuries occurring on or after January 1, 1994 a QME may obtain a consultation from any physician who has treated the unrepresented employee for the injury listed on the panel request form or by any physician as reasonable and necessary pursuant to Labor Code section 4064 or upon agreement by a party to pay the cost. (d) In any case where an acupuncturist has been selected by the injured worker from a three-member panel and an issue of disability is in dispute, the acupuncturist shall request a consult from a QME defined under s 1(n) to evaluate the disability issue(s). The acupuncturist shall evaluate all other issues as required for a complete evaluation. Note: Authority cited: Sections 139.2, 4061, 4062 and 4064, Labor Code. Reference: Sections 4061 and 4062, Labor Code. s 32.5. Rebuttal QME Examinations. (a) For injuries occurring between January 1, 1991 and December 31, 1993, an unrepresented employee shall have the right to a QME panel for one comprehensive medical-legal evaluation to rebut the findings of a panel QME, provided however, that the rebuttal evaluation is reasonable and necessary to resolve a disputed medical fact as defined in section 9793(e) of this Title. The employee shall notify in writing the claims administrator, or if none, the employer, the justification for the rebuttal evaluation. A copy of this notice shall be submitted to the Medical Director with this request. Reasonable and necessary justification shall include but not be limited to a discrepancy between the treating physician's conclusions and the QME's conclusions as to the level of permanent impairment, the need for medical treatment or the employee's status as a Qualified Injured Worker. (b) For injuries occurring on or after January 1, 1994, and upon request by the Appeals Board, the Medical Director shall assign a QME to address disputed issues provided, however, that the claims administrator or if none, the employer, agrees to pay for the cost of this rebuttal examination.

The form shall be filed with the Medical Director 30 days prior to the period of unavailability. The Medical Director may, in his or her discretion, grant a notice of unavailability within the 30 day period in cases of injury or illness to the QME or his or her immediate family. (b) It shall not be an acceptable reason for unavailability that a QME does not intend to perform comprehensive medical-legal evaluations for unrepresented workers. A QME who has filed notification for unavailability for more than 90 days during the QME fee period without good cause may be denied reappointment subject to Section 52. Good cause includes, but is not limited to sabbaticals or death of immediate family member. (c) If an unrepresented employee is unable to obtain an appointment for an evaluation with a selected QME within 60 days after an appointment request, the employee may report the unavailability of the QME to the Medical Director. The Medical Director shall provide a replacement QME at random to be added to the employee's panel in accordance with Section 31(d). The employee may choose to waive his or her right to replacement QME and accept a later appointment with the originally selected QME or select one of the two remaining QME's on the panel. (d) If a QME fails to notify the Medical Director, by submitting the form in Section 109, of his or her unavailability at a medical office due to a change in address for that office within 30 days of the change, the Medical Director may designate the QME to be unavailable at that location for 30 days from the date the Medical Director learns of the change in address. At that time, a certified letter will be sent to the QME by the IMC regarding his/her unavailability. If the IMC does not receive a response within 30 days of the date of certification of the letter, then the QME will be made inactive at that location.

This completed form shall be postmarked or sent by facsimile to the employee and the claims administrator or, if none, the employer within 5 working days of the date the appointment was made. Failure to comply with this requirement shall constitute grounds for denial of reappointment under Section 51. (b) The QME shall schedule an appointment for a comprehensive medical-legal examination which shall be conducted only at the medical office listed on the panel selection form. (c) The QME shall include within the notification whether a Certified Interpreter, as defined by Labor Code Section 5811 and subject to the provisions of section 9795.3 of this Title, is required and specify the language.

Reference: Sections 139.2, 4061 and 4062, Labor Code. s 35. Exchange of Information. (a) Where an employee is unrepresented, the claims administrator or, if none, the employer shall, and the employee may, provide to the QME: (1) All records prepared or maintained by the employee's treating physician or physicians; (2) Other medical records in their possession, including any previous treatment records, and/or non-medical records or information which are relevant to the evaluation of the employee's injury; (3) A letter outlining the issues which the QME is requested to address in the evaluation, which shall be served on the opposing party no less than 20 days in advance of the evaluation; (b) In no fewer than 20 days before the information is to be provided to the QME, the party providing such information shall serve on the opposing party the following: (1) A copy of all medical records and medical reports to be sent. (2) A copy of all non-medical documents or other non-medical information, including films or videotapes, to be sent. The claims administrator or employer shall include a cover letter or other document when providing such information to the employee which shall clearly and conspicuously include the following language: "Please look carefully at the enclosed information. It may be used by the doctor who is evaluating your medical condition as it relates to your workers' compensation claim. If you do not want the doctor to see this information, you must let me know within 10 days." (3) Copies of all records being sent to the QME shall be sent to all parties except as otherwise provided in section (c). Failure to do so shall constitute ex parte communication by the party transmitting the information under section (f). (c) In the event that the unrepresented employee schedules an appointment within 20 days of receipt of the panel, the employer or if none, the claims administrator shall not be required to comply with the 20 day time frame for sending medical information in subsection (b)(1) provided, however, that the unrepresented employee is served all non-medical information in subsection (b)(2) 20 days prior to the information being served on the QME so the employee has an opportunity to object to any non-medical information. (d) In the event that a party fails to provide to the QME any relevant medical record which the QME deems necessary to perform a comprehensive medical-legal evaluation, the QME may contact the treating physicians or other health care provider, to obtain such record(s). If the party fails to provide relevant medical records under section (a) within 10 days after the date of the evaluation, and the QME is unable to obtain the records, the QME shall complete and serve the report to comply with the statutory time frames under Section 38. The QME shall note in the report that the records were not received within the required time period. Upon request by the party, or the Appeals Board, the QME shall complete a supplemental evaluation when the relevant medical records are received. For a supplemental report the QME need not conduct an additional physical examination of the employee if the QME believes a review of the additional records is sufficient. (e) The QME and the employee's treating physician(s) may consult as necessary to produce a complete and accurate report. The QME shall note within the report new or additional information received from the treating physician. (f) If an employer or claims administrator communicates with a QME in violation of Labor Code section 4062.2, the Medical Director shall provide the unrepresented employee with a new panel in which to select a new QME or the employee may elect to proceed with the original QME. If an employee communicates with a QME either before or after the evaluation, in violation of Labor Code section 4062.2, the claims administrator or employer may request the Medical Director to issue a new panel to the unrepresented employee. The Appeals Board shall retain jurisdiction to determine whether ex parte contact has occurred in all cases. Note: Authority cited: Sections 139 and 139.2, Labor Code. Reference: Sections 139.2, 4060, 4061, 4062, 4062.2, Labor Code. s 35.5. Compliance by QMEs with IMC Guidelines.

Summary Form for Comprehensive Medical-Legal Evaluation Performed Pursuant to Labor Code Section 4061 by QMEs or AMEs; Service of Form and Evaluation. (a) Upon completion of either a comprehensive medical-legal evaluation or follow-up medical legal evaluation as defined under Section 9793(f) of this Title, of an unrepresented employee, the evaluator shall complete the QME/AME Findings Summary Form in Section 111. The Form shall not be required for a supplemental medical legal evaluation under 9793(k) of this Title. The evaluator shall serve the comprehensive medical-legal evaluation, the summary form, and DEU forms 100 and 101 on the employee, and the claims administrator, or if none, the employer, as well as the appropriate local DEU office within the time frames specified in Section 38. (b) If an evaluation is completed under subsection (a) for an unrepresented employee, in which the QME determines that the employees condition has not become permanent and stationary as of the date of the evaluation, the parties shall request any further evaluation from the same QME if the QME is currently an active QME and available at the time of the request for the additional evaluation. If the QME is unavailable, a new panel may be issued to resolve any disputed issue(s). If the evaluator is no longer a QME, he/she may issue a supplemental report as long as a face-to-face evaluation (as defined in section 49(b) of these regulations) with the injured worker is not required. In no event shall a physician who is not a QME or no longer a QME perform a follow up evaluation on an injured worker. Note: Authority cited: Section 139, Labor Code.

The injured worker shall have 15 days from the date of notice by the Medical Director to complete, sign and return IMC Forms 113, 115, 116 as applicable. If the employee requests a new panel, the claims administrator or, if none, the employer shall have no liability for the late report. If the employee is represented by an attorney and the extension is denied to an AME, either party may withdraw from the AME and no party shall be liable for payment to the AME. (b) For injuries between January 1, 1991 and December 31, 1993, the time frame for comprehensive medical-legal evaluations to be prepared and submitted shall not exceed 45 days after the QME or AME has seen the employee or otherwise commenced the comprehensive medical-legal evaluation procedure. Extension of the 45-day limit shall be approved when the evaluator has good cause or has not received test results or consulting physicians' evaluations necessary to address all disputed medical issues in time to meet the initial 45-day deadline. If the evaluation is not completed on the scheduled date through no fault of the QME, the QME may request an extension not to exceed an additional 45 days from the Medical Director. The evaluator shall notify the employee and the claims administrator or, if none, the employer not later than 5 days before the initial 45-day period expires that an extension is warranted. A copy of the notice shall be sent to the Medical Director. The notice shall be on the form in Section 112. If the extension of time requires additional days greater than 90 days from the date of the evaluation for the submission of the report, approval or denial shall be granted within 10 days by the Medical Director. (c) For injuries on or after January 1, 1994, the time frame for comprehensive medical-legal evaluations to be prepared and submitted shall not exceed 30 days after the QME or AME has seen the employee or otherwise commenced the comprehensive medical-legal evaluation procedure. Extension of the 30-day limit shall be approved when the evaluator has good cause or not received test results or consulting physicians' evaluations necessary to address all disputed medical issues in time to meet the initial 30-day deadline. If the evaluation is not completed on the scheduled date through no fault of the QME, the QME may request an extension not to exceed an additional 30 days from the Medical Director. The evaluator shall notify the employee and the claims administrator, or if none, the employer not later than 5 days before the initial 30-day period expires that an extension is warranted. A copy of the notice shall be sent to the Medical Director. The notice shall be on the form in Section 112. If the extension of time requires additional days greater than 60 days from the date of the evaluation for the submission of the report, approval or denial shall be granted within 10 days by the Medical Director.

Good cause means: (1) medical emergencies of the evaluator or the evaluator's family; (2) death in the evaluator's family; (3) natural disasters or other community catastrophies that interrupt the operation of the evaluator's office operations; (e) Extensions shall not be granted because relevant medical information/records (including Disability Evaluation Form 101 8 CCR s10161(b)) have not been received. The evaluator shall complete the report based on the information available and state that the opinions and/or conclusions may or may not change after review of the relevant medical information/records. (f) The time frame for supplemental reports in unrepresented cases shall be no more than 60 days from the date of a written or electronically transmitted request to the physician by a party. The request for a supplemental report shall be accompanied by any new medical records unavailable to the QME at the time of the original QME evaluation in compliance with section 10160(f) of this Title. An extension of the 60 days may be agreed to by the parties. (g) Evaluators giving notice of time extensions will be monitored and advised by the Medical Director when such notices appear unreasonable or excessive.

(b) When required as a condition of probation by the Council or his/her licensing authority, the QME shall disclose his/her probationary status. The QME shall be entitled to explain any circumstances surrounding the probation. If at that time, the injured worker declines to proceed with the evaluation, such termination shall be considered by the Council to have occurred for good cause. (c) If the injured worker declines to ask any questions relating to the evaluation procedure as set forth in Section 40(a), and does not otherwise object on the grounds of good cause to the exam proceedings under Section 41(a) during the exam itself, the injured worker shall have no right to object to the QME comprehensive medical-legal evaluation based on a violation of this section. Note: Authority cited: Sections 139.2 and 5307.3, Labor Code. Reference: Sections 139, 139.2, 4060, 4061 and 4062, Labor Code s 41. Ethical Requirements.

(5) Present a report that addresses all relevant issues, is ratable by the DEU, if applicable, and complies with all relevant guidelines of the Industrial Medical Council. (d) All aspects of all physical and/or psychological comprehensive medical-legal evaluations, including history taking, shall be directly related to medical issues as presented by any party or addressed in the reports of treating physician(s). (e) No physician certified by the IMC as a QME, or his or her agent, shall contact a QME for the purpose of influencing that QME's opinions or conclusions in any QME evaluation. (f) No QME shall schedule appointments to the extent that any injured worker will be required to wait for more than one hour at a QME's office prior to being seen for the previously agreed upon appointment time for an evaluation. If the injured worker is unrepresented and is not seen by the QME within one hour, he or she may terminate the exam and request a replacement evaluator from the Council. No party shall be liable for the terminated exam. The QME may explain any reasons for the delay to the injured worker and, provided both parties agree, the evaluation may proceed or be rescheduled at a later date. If the evaluation is rescheduled, the QME shall provide notice to the claims administrator or, if none, the employer within 5 working days after rescheduling the appointment. (g) If the injured worker terminates the examination process based on an alleged violation of either Section 40 or Section 41(a) and the Appeals Board later determines that good cause did not exist for the termination, the cost of the evaluation shall be deducted from the injured worker's award. A violation of Section 40 or of any part of section 41(a) shall constitute good cause for purposes of an Appeals Board determination. No party shall be liable for any cost for medical reports or medical services delivered as a result of an exam terminated for good cause. (h) Nothing in this section shall require a QME to undertake or continue a comprehensive medical-legal evaluation where the injured worker or his/her representative uses abusive language towards the QME or the QME's staff or deliberately attempts to disrupt the operation of the QME's office in any way. The QME shall state under penalty of perjury, the facts supporting the termination of the evaluation process. Upon request, the Medical Director shall investigate the facts and make a final determination of the issue(s).

The Method of measuring the psychiatric elements of a disability shall be as set forth below in the "Psychiatric Protocols" as adopted by the Industrial Medical Council on July 16, 1992, and amended on March 18 and October 25, 1993. Chapter I. OUTLINES OF EVALUATION REPORTS As a means of introducing some standardization to the contents evaluation reports, two model outlines are presented in this Chapter. Subchapter A, the Evaluation Report for Psychiatric Disability, is a guide for the physician, who may be either a psychiatrist or psychologist, who is conducting evaluation of psychiatric injuries. It assures that the clinician has provided all the information and opinions required b W.C.A.B. Rules of Practice and Procedure Section 10606. It also assures that the clinician has conducted the evaluation in a manner consistent with the requirements of the California Labor Code. Subchapter B, the Psychological Assessment Report, is a guide for the psychologist in those instances where the psychologist's role is to provide psychologist assessment as part of a collaborative evaluation report of psychiatric unjury. The latter's findings are to be assimilated into the evaluation report of the independent examiner, supported in detail by a complete psychologist assessment report which includes test scores. Additonal guidlelines with respect to psychologist testing are also provided. Whereas in psychiatry and psychology the process by which the historical data, excluding purely clerial intake data, e.g., patient identifier information, is collected is an intimate component of the psychiatric examination, collection of such information b any person other than doctoral level trained psychiatrist or psychologist is not accepable. The doctoral level trained psychiatrist or psychologist who authors the report must collect the historical information via the interview process. The use of other clinicians or non-clinicians cannot substitute for the evaluating clinician, and such reports are deficient. Furthermore, the use of other than the examiner to review the records and edit/write reprots is unacceptable. Not uncommonly, the psychiatric examiner reviews personnel files, military records, educational documents and other administrative reports that must not be delegated to the purview of others. Similarly, the nuances of psychiatric diagnosis and formulation of dunamic issues related to the crucial question of returning the employee to the work force must not come from other than a licensed doctoral level practitioner. The psychiatrist or psychologist who examines an applicant for Worker's Compensation on the basis of alleged psychiatric injury must conduct a careful interview of the applicant addressing elements of the outline for the evaluation report. To complete the interview almost always will require at least one to three hours of direct contact with the applicant by the examiner. In the case of applicants who have significant wxpressive/receptive English language deficits, interpreters may be used by the examiner. However, it is preferable that such applicants bay evaluated by examiners who can speak and also administer psychologial tests in the primary language. The use of interpreters may lead to distortion of the facts and misinterpretation of the data. Where, the psychologist is in the role of a consultant in the medical-legal assessment process, the duplication of certain efforts between the psychologist and the psychiatrist should not typically occur unless warranted by specific circumstances. It should not be necessary for the consultant to duplicate efforts at reviewing records and obtaining historical information in most cases. It may be necessary in the most comples cases where psychologist assessment is required that certain records and some portion of the history will need to be addressd by the consulting psychologist. A consulting psychologist is allowed to take a history if it is necessary. However, this is not a typical situation and in the routine case a thorough assessment by one clinician of the records and the obtaining of historical information should suffice. An explanation must br given when duplictive services are provided. The examiner should conduct such interviews as may be appropriate and possible and should review the psychologist assessment findings, the medical and employment and other documents or records [FN1] of the applicant, and other referral documents. When all this information is assembled, it should be documented in the report with a detailed description of the cognitive, effective, and behavioral signs/symptons of the applicant, as well as the psychological assessment scores and interpretations. It should be noted that the following outlines are more suggestive than prescriptive. The content of reports will vary with the referral questions, the nature of the applicant's presenting problems, and, to some extent, the practice of individual clinicians. The suggested headings are not required, but a systematic, quasistandardized report including all the relevant facts is likely t be most usefull to judges.

Guidelines for psychological testing Psychological testing is an additional source of information which can be combined with other elements such as reocrds review and clinical interview to arrive at opinions concerning diagnosis, symptom exaggeration and disability. Psychological testing includes self-administered inventories such as the MMPI which can be used to evaluate the clinical presentation of the patient. Psychological testing also includes the projective tests such as the Rorschach Test. Psychological testing also includes neuropsyhological tests which are used to identify and measure strenghts and weaknesses in case of suepected organic brain disorder. If psychological testing is included as part of the evalutation, these guidelines are to be followed: a. Routime Screening Battery Time: 2 to 5 hours Purpose: This category of psychological testing encompasses a routine Workers' Compensation case. This tesing may be done in conjunction with the Initial Comprehensive Evaluation. The purpose of this testing is to evaluate potentially disabling psychological factors. This psychological testing will look at self-reported symptoms such as depression and anxeity. This type of testing may also explore such issues as personality and possible exaggeration of symptoms. Types of Tests Used: This category of testing utilizes primarily self-administered questionnaires such as the MMPI and MCMI. Other standard test measures which are appropriate and necessary may be utilized. Persons Authorized to do the Psychological Testing: Psychiatrist, psychologist and registered psychological assistants with doctorate. within their respective areas of competence with respect to attained education, training, supervision and experience, are the individuals who will interpret psychological tests. Psychaitrists and psychologist are responsible for the production of psychological reports. b. Complex Psychological Testing Time: 6 to 10 hours Purpose: Here the referring evaluator who is conducting the Intial Comprehensive Examination requests more extensive psychological testing. Complex psychological testing gives an in depth view of the patient. Routine testing relying upon self administered inventories may be insufficient in cases where elaboration; reading, language and intellectual barriers; or confusional state exist. This level of testing can be used to explore more thouroughly issues of personality, cognition, and malingering and/or exaggeration. Types of Tests Used: Here the psychological testing is more extensive. Projective tests such as the Rorchach Test may be used. More extensive personality tesing may be utilizied. The Wechsler Adult Intelligent Scale may be utilized. Other standard test that are necessary and appropriate outside of these measures should be used. Persons Authorized to do the Psychological Testing: Complex psychological testing utilizes a psychologist or a registered psychologist. When a registered psychological assistant is utilized in the administration or scoring of some of the tests, this id done under the direct supervision of a licensed psychologist. The licensed psychologist is responsible for interpretation of complex testing and the production of the psychological testing report. How to Request Cpmplex Psychological Testing: Complex psychological testing is done at the discretion of the evaluator doing the Initial Comprehensive Evaluation. In the body of the Initial Comprehensive Report the evaluator must document that complex psychological testing which goes beyond te usual routine screening battery is indicated. The justification for the more thorough battery must be detailed by the disability evaluator in his/her report. c. Neuropsychological Testing Time: 8 to 15 hours Purpose and Criteria Warranting Testing: There are instances where the neuropsychological approach to assessment is indicated to help determine the role an orfanic mental disorder plays in disability. This is not a routine type of evaluation in Workers' Compensation cases and, when used, must be justified by the report. Typically there is a specific head injury, toxic exposure or some other situation that raises the issue of organic brain syndrome. Here the patient often registers impairments on the mental status examination and there is a history consistent with serious congnitive dysfunction. A condition such as depression, anxiety, and chronic pain may cause a complaint of congitive difficulties but this type of situation would not necessarily warrant neuropsychological testing. The mere report from the patient that there is difficulty with recent menory in and of itself cannot justify extensive neuropsychological testing. Types of Tests Used: This category of testing utilizes a number of cognitive tests in the form of an organic testing battery. Test such as the Luria Nebraska or the Halstead Reitan may be utilized by not always required in a neuropsychological testing evaluation. The neuropsychological test battery may incluede other standard measures such as the MMPI beyond those used exclusively for assessing cognition. Persons Authorized to do th Psychological Testing: This type of evaluation is done by a clinical psychologist with experience in evaluation organic mental disorders. A registered psychological assistant with doctorate may participate in the test administration and data interpretation. 8. Evaluation procedures. Refers to Chapter I, subchapter A, section 11, "Ranges for Psychological testing". List instruments when used in the following order. Indicate date and total administrative time. (This is a reporting format and does not necessarily imply that procedures be administered in this order.) a. Objective tests measuring general cognition b. Neuropsychological tests if indicated c. Objective (standardized and normed) tests relating to personality and emotional state d. Self-report inventories relating to emotional state e. Projective devices f. Interview 9. Results and discussion a. Describe assessment findings, providing test scores and documentation sufficient to permit other psychological examiners to review issues raised and opinions rendered. (Indiacte if computer scored/interpreted and give score.) Relate test findings to observations and relevant history, with emphasis on the vocational sphere. b. Relate all assessment findings to DSM-III diagnosis on Axis I, Axis II and, when appropriate, Axis III. (Note: It is inappropriate for a psychologist of offer independent Axis III diagnosis.) c. Current findings and inferecnes relative to work injury and job-related impairments. (The psychologist should follow "XV. Summary and Conclusions" in the Evaluation Report for Psychiatric Disability, but should include the additional information below.) (1). Distinguish between transient/situational conditions and enduring/ permanent condition. (2). Where appropriate describe and document with test findings and range and severity of psychological impairment with respect to ability to work in the same job or to compete on the open job market. (3). Describe and document with test findings what types of intervention are required to return applicant to the same job or to rehabilitate applicant for other emplyoment with amounts of time involved. Chapter II CLINICAL EVALAUTION OF PERMENENT PSYCHISTRIC DISABILITY In evaluating an applicant with an alleged psychiatric disability, the examiner should first decide: (1) whether or not there is any emotional or mental condition which handicaps the applicant in competing on the open job market, (2) whether or not this disability is to any degree work-related, and (3) whether or not the disability is permanent and stationary, that is, whether or not the applicant can receive further benefit from treatment at this time. If it is the examiner's opinion that there is psychiatric disability which is to some degree work-related and that maximum beneift from treatment has ben reached, then the applicant may be evaluated for permanent psychiatric disability. (California Casualty Ins. Co. v. W.C.A.B. (Jackson) (1985) 50 C.C.C. 262, 264; 167 Ca. App. 470, 476, 213 Cal. Rptr. 420) The examiner will proceed to evaluate the extent and nature of the disability and to describe the prognosis according to the guidelines presented in this section. The examiner will indicate whether or not actual events of employment were responsible for at least 10% of the total causation from all sources contributing to the psychiatric injury. The guidelines ask the examiner (1) to diagnose the applicant to DSM-III [FN2] to evaluate the applicant's ability to perform specific work funcions, and (3) to provide information concerning the applicant's prognosis. To assist the examiner and the court, schedules for summarizing relevant information are provided. The values in these schedules are not substitutes for the discussion described in the Summary and Conclusions, Chapter I, A., 16. They are vallues to be used in documenting or supporting the conclusions. A. Evaluation of the Nature and Severity of Impairment This subchapter provides the examiner an outline with which to describe the nature and severity of the applicant's mental or emotional impairment. This subchapter provides for Axis I and Axis II diagnoses, and also an Axis III diagnoses were occupationally disabling prior to the alleged injury and support the opinion. This subchapter also provides that the examiner list all symptoms related to the Axis I diagnosis or diagnoses and to state whether they are constant, intermittent, or occasional. Next the examiner is asked to evaluate the level of impairment in the applicant's ability to perform eight work functions. The Work Functions Impairment Form (Exhibit "A") provides a convenient way to summarize this information. The eight work functions are listed in Exhibit "B" hereto. The evaluation is performed as if there were no question of apportionment, even when apportionment is suggested by the examiner's assessment of the etiology. [FN2] The use of Diagnostic and Statistical Manual of the Mental Disorders 3rd Edition (DSM-III) includes referral to all subsequent revisions and/or editions as they become available and appropriate to the evaluation. 1. DSM-III diagnosis a. Axis I b. Axis II c. Axis III 2. List all diasbling symptoms and state whether each is constant, intermittent, or occasional. ("Intermittent" means present half time; "occasional", less than half the time.) 3. Using the levels defined in a.(1)-a(5) below, describe the extent to which disabling symptoms lead to impairment on the eight work funcions shown in b. below. a. Level of impairment: (1). Minimal (discomfort, but not disabling) (2). Very slight (detectable impairment) (3). Slight (noticeable impairment) (4). Moderate (marked impairment) (5). Severe (unable to perform work function) b. Work function: Document those symptoms which impair each of the following work functions and the levels of impairment on the Work Function Impairment Form on page. (See Exhibit "B" for descriptions of the work funcions.): (1). Ability to comprehend and follow instructions (2). Ability to perform simple and repetitive tasks (3). Ability to maintain a work pace appropriate to a given workload (4). Ability to perform complex or varied tasks (5). Ability to relate to other people beyond giving and receiving instructions (6). Ability to influence people (7). Ability to make generalizations, evaluations or decision without immediate supervision (8). Ability to accept and carry out responsibility for direction, control, and planning Information on severity of symptoms in referenced in 2 above will assist the Court to determine the level of severity of impairment of work function (factors of disability).

The method of measuring the pulmonary elements of disability shall be as set forth below in the "Guidelines for Evaluation of Pulmonary Disability" as adopted by the Industrial Medical Council on December 4, 1997. STATE OF CALIFORNIA GRAY DAVIS, GOVERNOR DEPARTMENT OF INDUSTRIAL RELATIONS INDUSTRIAL MEDICAL COUNCIL 395 Oyster Point Blvd., Ste. 102 South San Francisco, CA. 94080 Tel: (650) 737-2700 Fax: (650) 737-2980 ADDRESS REPLY TO: P.O. Box 8888 San Francisco, CA 94128-8888 Guidelines for Evaluation of Pulmonary Disability Adopted December 4, 1997 I. PURPOSE This document defines the following: 1. Criteria to be used for establishing the presence or absence of respiratory impairment; 2. Criteria for selecting appropriate use of laboratory data and for indentifying inappropriate testing; 3. A method for the quantitative and objective assessment of the extent or respiratory disability. 4. Guidelines regarding the content of medical-legal reports for assessing respiratory disability. II. GENERAL PRINCIPLES A. Aproach 1. Evaluation of subjective (dyspnea) must be subject to collateral evidence and the internal consistency of the history. The dyspnea criteria are used for rough estimates and cannot by themselves establish a level of impairment without one or more of the physiologic determinants listed below in the same class of impairments. 2. In any evaluation, the physician shall progress from the simple to the more complicated. Start wiht the history and phycial examination, follow with basic pulmonary function test, and then proceed as appropriate to more complicated procedures. Some patients will require only spirometry, but most will require determination of diffusing capacity for carbon monoxide (D<> co), and many will need lung volume measurement. Refer to Chapter 5, "The Respiratory System in "Guides to the Evaluation of Permanent Impairment" of the American Medical Association, 4th Edition, 1993. These guidelines shall be used in conjunction with the determinants discussed below. B. Evaluation Tests 1. Spirometry a. Spirometry must be performed according to the 1994 American Thoracic Society Recommendations. Equipment, calibration, and techniques must be according to these American Thoracic Society criteria. b. A spirogram representing the best effort of at least three attempts is used to calculate FEV<>1 and FVC. The two best efforts must be within 5% of each other, or additional efforts are needed. Hard copies of the spirogram must be incorporated in the report or maintained by the physician for review if needed. c. If wheezing or other evidence of brochospasm is present or if the FEV<< sub>>1/FVC ratio is reduced, perform test before and after brochodilator. If albuterol, metaproterenol or isoetharine is used, wait 10 minutes or more before testing. The examiner shall comment on what treatment program the subject has been on during the two months before the testing. A. diagnosis of asthma must be supported by objective evidence of airway hyperresponsiveness such as abnormally low (below the 95% confidence level) FEV<>1 or FEV<>1/FVC ratio , which is reversible, or a positive methacholine challenge test. (Astma may be present and the FEV<>1 and FEV<>1/FVC ratio not reversible, if examinee is on bronchodilator at time of testing.) If FEF 25-75% is abnormal (below the 95% confidence level) in a non-smoker, then asthma may be present, but additional testing such as methacholine or histamine challenge may be performed. Whenever possible, the patient should discontinue aerosol brochodilator treatment at least 12 hours before tesing. d. Compare test results to the tables of predicted normal values in the Chapter 5 of Guides to the Evaluation of Permanent Impairment of of the American Medical Association, Fourth Edition, 1993. Where FEV<>1 or FVC value is outside the 95% confidence interval, it is considered abnormal. Where FEV<>1/FVC value is less than 0.70 or outside the 95% confidence interval, it is considered abnormal. e. Analysis should be based on the FEV<>1, FVC, the FEV<>1/FCV ration. f. Tracings and all data must be submitted with the report or maintained on file for review. 2. Diffusing Capacity a. Single-breath diffusing capacity forcarbon monoxide (D<>co) shall be performed routinely unless asthma has been established as the sole cause of dyspnea or spirometry alone establishes severe impairment. b. D<>co measurement must be done according to the 1994 American Thoracic Society Epidemiology Standardization Project Recommendations. c. D<>co tracings and all data must be submitted with report or maintained on file for review. d. Either Cotes, Crapo, or methods published in peer-reviewed journals for predicted values may be used. e. D<>co less than 50% predicted indicates significant impairment. If spirometry is normal, exercise testing may be indicated to determine the extent of impairment. f. When the D<>co is between 50-70% of predicted impairment, evaluation may require exercise testing. 3. Exercise Testing a. The minimal requirements for performance of an adequate pulmonary exercise test include the following: (1) Supervision and interpreation by a physican thoroughly trained in pulmonary physiology and with special expertise in clinical pulmonary exercise physiology. (2) A standardized quantifiable exercise system (either a treadmill or a bicycle ergometer). (3) Ability to measure heart rate, respiratory rate, minute ventilation, and oxygen consumption following appropriate quality control and validation procedures. (Note: oxygen consumption must be measured, not estimated, from the level of exercise.) (4) Equipment for measuring arterial oxygenation by in-dwelling arterial catheter or pulse oximetry, and personnel appropriately qualified in its use. The blood gas measurements (pH, PCO<>2, PO<>2) must be made in a laboratory which successfully passes a professional society's proficiency testing program annually (e.g., program of California Thoracic Society or College of American Pathologists). In many instances, properly performed oximetry (to measure O<>2 saturation of hemoglobin) can be used as a substitute for measurement of arterial PO<>2. (5) The exercise testing must be performed with cardiac monitoring in a medical facilty capable of handling any complications and, in addition, capable of performing resting lung studies. An experienced physician must be on site. b. Written interpretation must include answers to the following questions: (1) Was the test technically satisfactory? (2) Describe the maximal exercise level achieved as the predicted percent of both heart rate and maximum oxygen consumption (VO<>2max). Include in the report the source of the prediction values used. (3) What is the estimate of the meximum exercise level which patient can sustain? Include a statement or literature reference which provides the rationale on which this prediction is based. (4) If limitation of exercise is found, what is the cause (pulmonary or non-pulmonary)? In all cases, include a description of the specific symptoms which limited the maximal level of exercise. c. Indications for Exercise Testing (1) If spirometry indicates Class 2 or Class 3 impairment (See Table 2) but there is dyspnea two levels higher (Class 4 or Class 5, respectively) and the dyspnea is not explained by tests for episodic bronchospasm, exercise testing may be indicated. (2) If spirometry establishes Class 4 or Class 4 impairment, exercise testing is contra-indicated. (3) If tests for airway hyperresponsiveness, exercise induced, antigen induced, or irritant induced episodic bronchospasm are positive and if the degree of impairment can be calculated from spirometric data demonstrating the most severe level of bronchospasm reached during the study, exercise testing is usually not needed since the most severe level of impairment in the presence of the inciting agent is known. The physician must provide specific information on the nature of the bronchospasm inducing agent and its prevalence in the job market. (4) Exercise testing may be needed in some patients with episodic dyspnea to determine if exercise induced bronchospasm is present. If done for this purpose, spirometry must be performed immediately before and after the exercise. (5) If spirometry and D<>co are normal but there is marked dyspnea and there are significant clinical findings such as positive x-ray examinations showing interstitial disease (i.e., ILO category 1/0 or greater) or hypoxemia (PO<>2 less than 80, according to the Guidelines for the Use of ILO Int'l Classification Radiographs of Pneumoconioses, Geneva: ILO, 1980. Occupational Health and Safety Services No. 22 Revised), exercise testing may be needed. 4. Airway Hyperresponsiveness Testing a. Tests of airway hyperresponsiveness are indicated when asthma is a consideration. This is particularly relevant when the patient complains of episodic dyspnea. b. In such instance, if the FEV<>1/FVC ratio is reduced and the FEV<< sub>>1 is less than 60% of predicted, an aerosolized bronchodilator shall be administered. A consistent response (based on accurate testing and maximal patient effort) with greater than 15% increase in FEV<>1 indicates that airway reactivity is present. c. If the FEV<>1/FVC ratio is normal or reduced, and the FEV<>1 is greater than 70% of predicted, a provocation challenge test shall be considered if the clinical history suggests the presence of possible disability due to asthma. In such instances, a methacholine challenge or histamine challenge test shall be performed. Such tests shall only be performed by physicians with experience in their conduct. These tests require careful attention to technical detail. In particular, establishment and maintenance of precise concentrations of the methacholine agent is requisite. False positive and false negative tests may occur if not performed well, and therefore spirometry tracings must be retained for review. d. Additional information about the specific techniques of the methacholine challenge may be determined from standard references. 5. Treatment A careful history of the nature of ongoing treatment for pulmonary conditions must be obtained by the phsician performing the evaluation. It is particularly important in cases of asthma to express an opinion about whether optimal therapy is being provided. If the examining physican feels that adequate therapy if not provided, this should be stated explictly and suggested alternatives should be indicated. In addition, if the examining physican believes that the patient is not complying with treatment, this should be stated. The National Institute of Health guidelines ("Medical Care", Vol. 31. No. 3, pp MS20-MS28, Supplement, 1993, "The National Asthma Education Program: Expert Panel Report Guidelines for Diagnosis and Management of Asthma") for the treatment of asthma shall be used as a reference standard for determining the adequacy of treatment. In general, a patient shall be treated with the minimal drug which is necessary to maintain control of the asthma. Additional guidance is available on the 1993 American Thoracic Society statement on Disability and Impairment from Asthma. 6. Chest Radiography Chest radiographic examinations are an essential part of most pulmonary disability evaluations. For evaluating possible pneumoconioses (dust diseases of the lung), it is essential that the radiographs be of high technical quality. Over or under penetration can lead to under or over diagnosis of the presence of pulmonary abnormality. The recommendations of the International Labor Organization (ILO) Committee on chest radiography, Guidelines for the Use of ILO Int'l Classification of Radiographs of Pneumoconioses, Geneva: ILO, 1980. Occupational Health and Safety Services No. 22 Revised), shall serve as the reference guideline. The physican interpreting the radiographs must be experienced in evaluating occupational and environmental lung disease (e.g., such as by being an A or B reader as certified by the National Institute for Occupational Safety and Health). CAT scans are not routinely necessary in the evaluation of dust exposed individuals. Their use shall be limited to those situations where a specific indication exists (e.g., to radiographically evaluate the parenchyma in the presence of extensive pleural abnormality). CAT scans are not indicated for the evaluation of individuals who have been dust exposed but have normal lung function and no symptoms. They are required only if finding the deviation from complete normality will affect the ratable disability. Table 1.

The single most significant factor should be used. III. PROCEDURES FOR ASSESSMENT Clinical assessment for establishing disability under the Workers' Compensation system will proceed in an organized stepwise fashion. First, the history obtained from the patient shall include description of the presence or absence of symptoms shown in Table 1. For each symptom shown, the date of onset, previous severity, and current severity shall be described. Second, the evaluating physician shall personally obtain a history from the patient of the nature of work and possible chemical exposures. In addition, the physican shall personally inquire about any mitigating factors such as the use of respirators or industrial ventilation. Where appropriate, information obtained about exposures from the patient shall be supplemented by industrial hygiene or other information. Third, the physician shall personally obtain a history of cigarette smoking, including past and current practices. Other tobacco use shall also be determined. Fourth, the physician shall ask about non-occupational exposures (e.g., pets, hobbies with chemical exposure). Fifth, a carefuly history of current and previous treatment for pulmonary conditions shall be obtained by the physician. Sixth, the physician shall perform a careful physical examination. Seventh, the physician shall choose laboratory testing based upon the nature of exposures, the symptoms, and the examination. Guidelines for the utilization of such testing were presented in Section II. IV. ASSESSMENT OF IMPAIRMENT AND DISABILITY RATING A. General Approach The available clinical information and laboratory tests, particularly pulmonary function tests, shall be integrated into an assessment of disability. Tables 3 through 4 provides guidelines for this. Based upon the physiologic findings, a patient is placed into one of five classes. If post-bronchodilator testing is performed, the best of the pre-bronchodilatory or post-bronchodilator test results are used for classification. (Asthma is considered subsequently.) Because of the excellent reliability of properly performed pulmonary function testing for assessing impairment, symptoms alone (e.g., shortness of breath) do not warrant classification into a class indicating disability. However, the presence of dyspnea disproportionate to the corresponding physiologic findings indicates the need to consider more careful evaluation (e.g., exercise testing, methacholine challenge testing, search for a nonpulmonary explanation of dyspnea, or psychosocial evaluation). Table 2, derived largely from the 1993 AMA Guides to Permanent Impairment, 4th Edition, assigns individuals to physiologic classes. Table 3 interconverts the classes to typical disability impact terms. The data have been derived to be consistent with Workers' Compensation recommendations for cardiac disability in the State of California. For each class, the typical corresponding maximum attainable oxygen consumption measurement is provided. For disability rating it is assumed that 45% of peak attainable oxygen consumption can be sustained throughout the workday. In many cases the sustainable oxygen consumption can be estimated from the bona fide pulmonary function testing. Although lifting ability is not directly determined by lung function, the Workers' Compensation system uses a lifting base terminology. Therefore, a "preclusion equivalent" is included in Table 3. The "preclusion equivalent" is designed to interconvert these ratings to the terminology typically used in Workers' Compensation evaluations. B. Special Consideration for Asthma Evaluation Unfortunately, physiologic testing along may not, in some instances, provide complete information. For example, physiologic testing does not provide information on the impact or regular usage of medication. Table 4 provides a list of such modifying factors and the effect on the impairment schedule listed in Table 2. These must be considered in addition to the physiologic data. Of particular importance is bona fide occupational asthma due to sensitization to a specific workplace chemical (e.g., TDI). An individual who has true sensitization shall be considered permanently disabled for any job which involves exposure to that agent. Numerous research studies have demonstrated that the diagnosis of true sensitization chemical specific occupational asthma is difficult, and there is considerable misdiagnosis. Because of the great impact on the individual involved, such diagnoses shall be made only by physicians with particular training and expertise in sensitization occupational asthma. Asthma is particularly difficult to evaluate because the extent of disability depends upon the adequacy of treatment. Therefore, Table 4 provides supplemental guidelines for assessing asthmatics. Prior to use of this, the diagnosis itself must be firmly established by one of the following two methods: a. Abnormal FEV<>1 with a greater than 15% increase after aerosolized bronchodilator administration. (Note, this must be done extremely carefully and well documented to avoid false positives.) b. A methacholine challenge test showing a PC<>20 of less than 20 milligrams. In Table 4, the need for medication may be considered an indication of severity of disease. In such instances, the need for medication must be carefully documented in order to assure that the patient is receiving the minimal medication necessary to maintain control of asthma. To make such an assessment, the evaluation physician must be skilled in the treatment of asthma. The National Institute for Health Guidelines "Medical Care", Vol. 31, No. 3, pp MS20-MS28, Supplement, 1993, "The National Asthma Education Program: Expert Panel Report Guidelines for Diagnosis and Management of Asthma" may be helpful as a reference standard.

The method of measuring the cardiac elements of disability shall be set forth below in the "Guidelines for Evaluation of Cardiac Disability" as adopted by the Industrial Medical Council on December 4, 1997.

Previous Cardiac History Including Myocardial Infarction, Coronary Artery Bypass Surgery, or Coronary Angioplasty SECTION III: DISABILITY EVALUATION SCHEDULE FOR THE HEART SECTION I: CLINICAL AND LABORATORY APPROACH TO CARDIAC DISABILITY EVALUATION A. General The clinical and laboratory approach to cardiac disability evaluation in Workers' Compensation is essentially no different from any other detailed exhaustive medical consultation. The physician shall start with a comprehensive history and physical as detailed below. This is the cornerstone of any good exhaustive evaluation. Beyond that, a judicious and minimal number of tests must be utilized to arrive at a disability rating. It is not uncommon at all after a comprehensive history and physical that there will be no further testing necessary. On the other hand, it is often thought that other testing are required and they will be discussed in detail below. However, by no means does this imply that all these testings need to be done. The listed testing are merely a number of clincial and laboratory testings that are useful in different clincal circumstances in evaluating a cardiac patient. It is anticipated that in most cases an evaluation considering all the medical records, what tests have been done previously, the history, the physical, the electrocardiogram, and some form of exercise testing will be more than adequate in determining a disability rating. The additional testing listed shall be done only in the special circumstances described. When these additional testing are utilized, full explanation to the justification of the testing must be included so that the reviewing agencies or the reviewing physician can determine its reasonableness in reimbursing medical-legal costs. Testing of any kind is not to be repeated more than every 6 month unless there is evidence of a change in the clinical condition. If a physician decides to repeat the testing in less than 6 months' time, he or she must explain the necessity of such repeated testing. The physician shall inform the applicant of any significant medical finding(s) which could impact on his or her health even though these findings may not be directly related to the cardiac claims. B. History and Physical The cornerstone of a comprehensive medical evaluation is the history and physical. The history shall consist of a complete detailed history of the industrial injury, occupational history of the present occupation as well as past occupations; medical history of all prior hospitalizations, treatments, surgeries, and medical illnesses; family history; hsitory of habits such as smoking, drinking and the use of drugs; history of the current illness, the sequence of events, the present complaints as well as a complete list of all present medications. When determining whether an occupational event is related to cardiac disability, the applicant shall be asked specifically why he or she feels the cardiac problem is related to the work. Complete details of the current illness shall be reviewed, including circumstances of the industrial event or events relating to the cardiac condition, any previous or similar episodes of the same type of event which might have occurred away from the job, prior to the job, or during previous jobs. A complete list of all doctors who have treated the applicant for the illness shall be obtained in order to facilitate obtaining medical records that have not always been obtained before. A complete listing of all the complaints at the time of the examination as to the duration, degree and nature shall be included. This is especially important when listing subjective complaints of permanent disability in the final report. Details of temporary disability shall be recorded, including whether the patient is working, and what effect going back to the work had on the illness, if any, or, if not working, whether the patient plans to return to work. These details bear on the patient's ability to do the same type of work, or whether the patient is a qualified injured worker and thereby a candidate for vocational rehabilitation. All medical records shall, to the extent possible, be obtained prior the evaluation. The evaluator must be familiar with the medical record and its salient features in order to better direct the questions and evaluation and better outline the issues to be evaluated. A comprehensive detailed physical examination shall be performed. If part of the examination such as detailed neurological examination is to be omitted, it must be so stated. Blood pressure shall be taken in supine and upright positions on both arms several times by the physician. Other physical findings expecially germane to the cardiac examination such as fundoscopic examination, neck vein status, cardiac auscultation, and extremities' examination must be specifically mentioned and recorded. C. Routine Laboratory Testing Routine laboratory studies such as CBC, chemistry panel and urinalysis and thyroid functions, are generally useful in evaluating the general medical status of the patient. An electrocardiogram as well as a chest X-ray may be performed since they are relatively inexpensive and informative. Again as stated above, if any of this examination has been performed recently within 6 months, it must not be repeated unless indicated. D. Stress Testing Exercise stress testing is currently the most important and productive means of quantitating a worker's impairment. Protocols and guidelines for exercise testing on the treadmill utilizing the Bruce protocol and holding the front handrail and bicycle ergometer have been documented and quantitated. See Tabe 2 for comparison of exercise test standards. Reports of stress testing to rate a worker's impairment shall include the following information: 1. Peak level of activity achieved, preferably expressed in METs (metabolic equivalents of oxygen consumption). 2. Any clincial signs or symptoms reported or observed. 3. Record of ectopic (ventricular or supraventricular) activity. 4. Specific EKG (ST segment and T wave) changes noted. 5. Accurate description of, and timing of development of, such symptoms as dyspnea, angina, ischemic ST segment change or arrhythmia. 6. Blood pressure response. The end point of exercise testing shall be either to achieve maximum capability or to develop any of the following symptoms and signs noted below. If the examiner does submaximal testing, stopping at "90% of expected" for example, 10% shall be added to the METs level calculated from the Bruce or other testing protocol tables. The examiner must specify which symptom(s) or sign(s) caused testing to be stopped and shall fully explain why cardiac impairment (rather than some other condition) caused testing to be stopped. If the test subject stops voluntarily before reaching what his or her physician considers maximum capability, the examiner shall state an opinion as to what the true testing end point should be, giving reasons. Significant sections of the tracing, including scale as well as technical description of the equipment used, shall be enclosed with the report. The signs and symptoms indicating the end point shall be the following: 1. Onset of atrial fibrillation. 2. Onset of ectopic atrial tachycardia. 3. Progressive drop in heart rate as exercise continues, or if systolic blood pressure falls 10 mm below prior measured level as exercise continues. 4. Progressive ST segment elevation or depression. 5. Progressive widening of the QRS complex or PR interval. 6. PVCs with increasing frequency to the point of danger. 7. Ventricular tachycardia (3 or more consecutive beats). 8. Excessive blood pressure rise (230 mm HG systolic or above). 9. Undue dyspnea; subjective evaluation by test subject that dyspnea is not acceptable (usually coupled with #10 below). The examiner must state whether the testing end point is or is not a valid measure of cardiac capability and give reason(s) for the opinion. 10. Undue fatigue: subjective evaluation by testing subject that fatigue is not tolerable (usually coupled with #9 above). The examiner must state whether the testing end point is or is not a valid measure of cardiac capability and give reason(s) for the opinion. 11. Feeling of faintness: subjective evaluation by test subject. The examiner shall state whether the testing end point is or is not a valid measure of cardiac capability and give reason(s) for the opinion. 12. Angina pain progressive to moderately severe: 3 or 4 on a scale of 4. The examiner shall state whether the testing end point is or is not a valid measure of cardiac capability and give reason(s) for the opinion. 13. Musculoskeletal pain or discomfort that limits continuance of the test the end point in this event is not valid for the evaluation of cardiac impairment. If pulmonary function testing is needed to rule out pulmonary factors contributing to decreased exercise tolerance, the physician shall include an explanation of its necessity. E. Newer Modalities In addition to stress testing, there are various newer modalities that can be very useful in the determination of disability. However, the physician performing and interpreting such testings shall have the appropriate training and experience. In addition, the physician shall be identified. Stress testing done in conjunction with thallium-201 is a more sensitive tool in the diagnosis of coronary artery disease. Its sensitivity has been reported to range from 68% to 96% (average 84%), compared with a sensitivity of 60% to 70% for exercise EKG alone. The specificity of thallium scintigraphy has been reported to be between 65% and 100% (average 87%), which represents a modest improvement compared with the specificity of exercise EKG alone. Thallium scintigraphy is often done with SPECT (single photon emission computed tomography) which further increases the sensitivity. However, a stress test with thallium is costly and has the undesirable side effect of exposure to radiation. A total body radiation exposure associated with intravenous injection of 2mCi of thallium-201 is approximately 420 mrad; this amount is equivalent to that of approximately 30 chests X-rays. Thallium scintigraphy, however, is preferable to exercise EKG alone when the resting EKG shows a non-specific abnormality impairing interpretation of exercise EKG alone or when information on the probable reversibility (or nonreversibility) of apparently infarcted segment is needed to estimate the potential value of revascularization therapy. In the majority of cases of disability evaluation, thallium testing is not necessary in determining the disability status, above and beyond what information that can be dervied from a standard exercise test. Technetium 99m sestamibi study is another form of studying perfusion of the heart. This radioactive study is similar to that of thallim 2001. With a combined approach using both thallium and sestamibi 99m, one can decrease the acquisition time by 50%. The information derived from these newer techniques allows for both evaluations of ischemia and data similar to a first pass MUGA study. This particular technique is more expensive than thallium imaging, but is of shorter time and is useful when information regarding wall motion abnormality and ejection fraction is important as well as the degree and area of ischemia. This obviates the need for ordering a MUGA scan. Adenosine or Dipyridamole thallium studies are newer modalities that allow studying perfusion abnormalities to the myocardium when the patient cannot perform a regular treadmill or bike testing. The physician shall order one of these studies only it is important to make an absolute diagnosis of coronary disease and the patient is unable to perform a treadmill test or a bike test. These studies do not allow for functional disability evaluation but only provide information regarding the presence or absence of myocardial ischemia. Echocardiography with stress test, with Adenosine, with Dipyridamole, or with Dobutamine have all been described. The information is that of wall motion abnormality indicating ischemia. Ejection fraction can also be measured. These tenchiques are somewhat less expensive than adionuclear studies, but require an experienced technician to obtain a satisfactory study. F. Echocardiogram Echocardiogram is a useful tool in determining left ventricular function, chamber size, wall thickness, valvular anatomy and function, and flow pattern as determined by Doppler study. It is, therefore, useful in the determination of left ventricular hypertrophy and left ventricular mass, diastolic dyfunction as demonstrated by abnormal flow pattern, and valvular heart disease such as mitral valve prolapse and aortic stenosis. Ejection fraction can also be accurately determined by echocardiogram. G. MUGA Scan Multi-Gated Equilibrium Radionuclide Angiography (MUGA) is a very accurate method in measuring ejection fraction. Rest and exercise equilibrium radionuclide angiography has been used in conjunction with or as an alternative to thallium scintigraphy in the detection of coronary artery disease. Regional or global abnormal wall motion at rest or during exercise can be accurately delineated with this technique. It is also a powerful predictor of subsequent adverse cardiac event. It is also useful in managing patients with stenotic or regurgitant valvular lesions. H. Holter Monitor Holter Monitoring is used in cases where arrhythmia is an issue. A 24-hour Holter Monitor is valuable in determining whether the applicant has a significant enough arrhythmia to be considered in the process of disability rating. For instance, there may be a very complex arrhythmia which would prohibit certain types of activities. High fidelity Holter Monitoring can also be done to determine whether patient has ischemia at various times of the day, which is not apparent on standardized exercise tests. It is especially useful in cases of coronary artery spasm. It is also useful in detecting silent ischemia. I. Coronary Angiography Corony angiography is the gold standard for diagnosing coronary artery disease. It is also the gold standard for determining the best mode of therapy, be it angioplasty, bypass surgery, or medical treatment. It is generally not a testing which is done for disability evaluation. However, if the data is included in the medical record, it should be part of the material used in determing the coronary anatomy, the amount of myocardial damage, the amount of myocardium at risk, the amount of myocardium with akinesis or hypokinesis, or the ejection fraction. This shall be used as adjunctive material for disability evaluation. However, in general the coronary angiogram defines the anatomy of the coronary arteries, not the functional aspects of the patient which are better determined by exercise testing, with or without other adjunctive studies such as thallium scintigraphy. SECTION II: OBJECTIVE AND SUBJECTIVE FACTORS UTILIZED IN CARDIAC DISABILITY EVALUATION A. Work Level By Stress Testing The acceptable exertional levelof sustained (8 hours per day) work relative to VO<>2 max is 45%. The VO<>2 max is estimated by the METs achieved at the end point of stress testing. When stress testing has been performed and the end point in METs has been determined, the physician can predict a "safe" effort for a given applicant with the above information in mind. If the testing end point is related to poor state of physical fitness, the maximal short-term (less than 15 minutes once a day) work exertion allowed shall be 80% of the end point level. If the subject is post-medical intervention for cardiac ischemia and is asymptomatic off the treadmill, the maximum short-term (defined as less than 15 minutes once a day) work exertion allowed shall be 80% of the testing end points in METS. If the testing end point is related to signs or symptoms of cardiac distress, as listed above, the maximum short-term (defined as less than 15 minutes once a day) work exertion allowed shall be 70% of the end point level. The sustained level of work exertion for activities through most of the work day for all patients shall be set at 45% of the testing end point in METs. B. Work Level By History And Previous Testing Occasionally stress testing is not feasible. However, work level can still be assessed in the following manner: (1) Activity levels reported (consistent with clinical picture) translated into METs. (2) Previous post-injuty exercise testing. (3) Documented level in post-injury exercise program in METs. C. Pre-Injury Work Level It is extremely important to determine the work level before the industrial injury. The pre-injury METs level found from one of the four following tests shall be used, in this order: ("Pre-injury METs level" is defined as that subsequent to the time the last of any known previous cardiac injuries became "permanent and stationary" and within the past five years preceding the instant injury). (a) If available, use previous measurement by exercise testing. (b) If (a) is not available, use previous capability by activity level within the past five years translated into METs. (c) If (a) and (b) are not available, use previous capability level by non-work activities, translated into METs. (d) If (a), (b) and (c) are not available, use mean standard METs for age and sex from Table 3. D. Ejection Fraction Ejection fraction may be used to estimate cardiac impairment in the absence of exercise testing or used to modify or validate medical opinion based on exercise testing. However, one may have normal resting ejection fraction even though impairment may still be present with major coronary occlusion. Therefore, ejection fraction is a supplement rather than an alternative to stress testing. Cardiac catheterization with direct measurement of cardiac output and cardiac index is an accurate method of measuring ejection fraction, but must not be routinely done for Workers' Compensation evaluation. If it happens to have been done for other reasons, the information provided is valuable if the test was done at a time reasonably close to the Workers Compensation evaluation. The physician shall explain why the data/information is considered relevant or not. Ejection fraction is best measured accurately by echocardiogram or MUGA scan. The following guidelines must be followed with regard to ejection fraction: (a) More than 55% is in normal range, equivalent in cardiac performance to the normal for age and sex (see table 3). (b) 45-50% is slight impairment. (c) 30-45% is moderate impairment. (d) Less than 30% is not quite severe impairment. (e) Less than 20% is severe or total impairment. E. Coronary Artery Spasm Coronary artery spasm must be diagnosed by EKA or Holter Monitor with S-T segment changes up or down more than 1 mm. The Holter Monitor must be a high fidelity type and not a standard or event recorder. S-T segments are usually elevated with coronary spasm and depressed with ischemia, but this is not always the case. Significant sections of the tracing, including scale, as well as a technical description of the equipment used, shall be included with the report. There are several types of coronary artery spasm. (1) Coronary artery spasm with pain, however the coronary arteries are normal. The relationship of this type of coronary artery spasm to emotional stress is somewhat controversial. It is not related to physical stress. (2) Coronary artery spasm with pain, however there are coronary artery occlusions. This type of chest pain is related to physical and/or emotional stress. (3) Myocardial ischemia without pain (silent ischemia). This is associated with fixed-lesion coronary artery disease. It is also related to emotional and/or physical stress. The impairment due to coronary artery spasm shall be evaluated after appropriate treatment, which shall be continued. The evaluator must describe the level of emotional and/or physical stress producing spasm and offer an opinion regarding the extent of the impairment, which shall be described in detail. The response to medication shall also be described. If the patient has nearly daily episodes not controlled with medication, it must be described as severe. If the patient has an episode every week or two despite medication, the impairment is described as moderate. If the patient has an occasional episode despite medication, the impairment is described as slight. If there are side effects from the medications, they shall be described in detail. F. Arrhythmia Arrhythmia should be evaluated after appropriate treatment and documented by data from EKG, Holter Monitor, event recorder, or data from stress testing. Any significant arrhythmia which terminates a stress test should automatically establish the impairment level. Occasional unifocal PVCs with an otherwise normal heart represents no impairment unless the PVCs are related to stress or because of the patient's marked preoccupation with symptoms. Ventricular arrhythmia in the presence of ventricular dysfunction or valvular abnormality is associated with an increased risk of sudden death. Supraventricular arrhythmia may result in impairment depending on the extent of subjective symptoms. G. Hypertension Hypertension is defined as a resting blood pressure over 140/90. The blood pressure must be taken multiple times in both arms, in both a supine and an upright position. It is extremely important to establish that hypertensin does exist. At times this requires multiple visits or 24-hour blood pressure monitoring. Hypertension is "controlled" when the blood pressure is lower than 140/90 with reasonable medication ("reasonable medication" means no untoward side effects). Any side effects shall be described and appropriate restrictions due to side effects must be stated. When there are no significant side effects, this shall also be stated. Blood pressure is "incompletely controlled" if there is an intermittent elevation of blood pressure higher than 140/90 with reasonable medication. Blood pressure is "uncontrolled" when the diastolic pressure is always higher than 90, with or without reasonable medication. If without medication, treatment is needed, the applicant may or may not be temporarily, partially, or totally disabled. In most cases, with effective treatment, hypertension can generally be controlled. The medication and dosage, as well as increases needed, must be noted. There is usually a period of time need to adjust medication until the blood pressure is controlled and side effects are tolerable. This period of time is generally no longer than three months. During this period of time, the patient may be temporarily, partially or totally disabled. If the period of time exceeds three months, as explanation must be provided. In terms of impairment factors, the side effects of the controlling medication may on their own warrant a finding of disability. The signs and/or symptoms must be described and quantified, and their relationship to the medication explained. In testing for "controlled" hypertension, ambulatory blood pressure monitoring, or treadmill testing may show intermittent loss of control. The leve of physical and emotional stress producing loss of control may be a basis for impairment rating. Such testing is ordered at the discretion of the physician. If there exists a "controlled" hypertension with end organ damage, the medical evaluator must describe and give the significane of the end organ damage. "Uncontrolled" hypertension may or may not be temporarily totally disabling. H. Emotional Stress The following guidelines shall be used for prophylactic restrictions from stress. All conditions the physician feels justify a preclusion from emotional stress such as those listed below, or any others the physician feels are significant, shall be under appropriate and continuing treatment. The reasons listed for prophylactic restriction below are examples. If prophylactic restrictions are suggested for reasons other than those listed below, the restriction must be justified by comparison with the examples given. The physician shall give examples of emotional stressors to be avoided by the patient. The physician shall be as specific as possible. (1) Prophylactic restriction against all emotional stress. Examples include: --recurrent complex cardiac arrhythmia persisting despite appropriate treatment. --unstable angina or rest angina at a frequency of three or more times a week, documented by history. --uncompensated heart failure. --EKG demonstration of silent ischemia persisting despite appropriate treatment documented by Holter Monitor and diary. (2) Prophylactic restriction from more than ordinary--for the person being examined--emotional stress. Examples include: --occasional episodes of complex arrhythmia or arrhythmias associated with undue or more than ordinary emotional stress document by Holter Monitor and diary. --angina with undue or more than ordinary stress. --compensated heart failure. --hypertension shown to become uncontrolled--with diastolic over 100 present 50% of the time or more--under undue or more than ordinary emotional stress. --EKG demonstration of silen ischemia under undue or more than ordinary emotional stress documented by Holter Monitor and diary. (3) Prophylactic restriction against severe emotional stress. Examples include: --arrhythmia precipitated by severe emotional stress documented by Holter. --angina precipitated by severe emotional stress. --documented decompensation or congestive heart failure precipitated by severe emotional stress. --hypertension which becomes uncontrolled by severe emotional stress. --EKG demonstration of silent ischemia with severe emotional stress documented by Holter Monitor and diary. --mitral valve prolapse: a mechanical abnormality which becomes symptomatic (chest paind and/or cadiac arrhythmias) under conditions of severe emotional stress. Mitral valve prolapse must be documented. --psychophysiological cardiovascular reaction. This includes clinical pictures of chest pain with no cardiac pathology and cardiac irregularity (palpitation of simple arrhythmia) for which no other organic cause is found. These symptoms are often precipitated by severe emotional stress. I. Previous Cardiac History Including Myocardial Infarction, Coronary Artery Bypass Surgery or Coronary Angioplasty I. Previous Cardiac History Including Myocardial Infarction, Coronary Artery Bypass Suergery or Coronary Angioplasty The previous history of myocardial infarction, coronary surgery, coronary angioplasty, atherectomy or coronary stent placement as a consequence of the incident injury shall be considered in a finding of disability and the resulting finding may or may not be absorbed in the (exercise capacity based) findings as the evidence directs. SECTION III. DISABILITY EVALUATION SCHEDULE FOR THE HEART The above clinical and laboratory approach to cardiac evaluation as described in Section I gives rise to the objective and subjective factors to be utilized in cardiac disability evaluation. The various factors were described above under Section II. The cornerstone of the disability, evaluation is work level, before and after the industrial injury as established by stress testing (Section IIA, IIB, IIC). 45% of the testing end point is the accepted level for sustained work. Consideration shall also be given to a need for maximum short term effort (less than 15 minutes once a day) in certain occupations. The 80% level in METs of the person's testing end point shall meet or exceed this short-term METs requirement. In arriving at the findings of disability, the physician shall consider the current work level status (Section IIA, IIB) and the pre-injury work level status (Section IIC). Using those two levels as measured in METs, the physician shall calculate the percentage of impairment as a result of the industrial injury: % of impairment = (1-current work level/pre-injury work level) x 100% For example, if a worker had a pre-injury work level of 12 METs, after his industrial injury his current work level has been determined to be 8 METs, his % of impairment is (1 - 8/12) x 100% = 33 1/3%. The miimal METs required for mere surviving (generally less than 2.5 METs), that is without any capacity of any work, may be taken into consideration and may be used to modify the above formula. When the determination of pre-injury work level is not feasible, Table 4 is offered as a guide to estimate minimum work preclusion on the basis of current work level. Other objective and subjective factors ad described in Section II shall be considered when they are appropriate in arriving at the final disability finding. If symptoms and signs of coronary artery spasm, arrhythmia, hypertension or emotional stress cause exercise tesitng to be stopped, disability for those clinical factors would be at least partially "absorbed" in the (exercise capacity based) disability findings. Otherwise (if there are no symptoms or signs resulting at the time) if coronary artery spasm, arrhythmia, hypertension or emotional stress given rise to non-scheduled disability findings, these findings may or may not be absorbed in the (exercise capacity based) disability findings as the evidence directs. If they physician feels comfortable with using the Guideline for Work Capacity (Table I) directly without calculating the percentage of impairment, he may do so.

The method of measuring the neuromusculoskeletal elements of disability shall be as set forth below in the "Guidelines for Evaluation of Neuromusculoskeletal Disability" as adopted by the Industrial Medical Council on October 20, 1994. GUIDELINES FOR EVALUATION OF NEUROMUSCULOSKELETAL DISABILITY I. INTRODUCTION A. BASICPURPOSE OF THE GUIDELINES The purpose of these evaluation guidelines is to develope a more uniform method of evaluating musculoskeletal injuries without diminishing the individual expertise of the participating evaluator. This method will allow involved parties (particularly the WCAB) to review evaluator's reports which employ a more standardized format. B. GENERAL APPROACH The evaluator shall personally take the history from the injured worker and perform the examination. The evaluator may have an assistant make an initial outline of the injured worker's history or take excerpts from prior medical records, however the evaluator must review the excerpts and/or outline with the injured worker. Occupational and medical questionnaires may be useful to assist the injured worker in compiling the details of the injury prior to the consultation with the evaluator. Any discrepancies in the various sources of information should be identified and clarified by the evaluator. The injured worker shall at all times be evaluated in a compassionate and respectful manner. The evaluator will introduce him/herself, and explain to the injured worker the purpose and scope of the evaluation. The evaluator must inform the injured worker of any significant medical findings which could impact on his or her health. These findings may not be directly related to the work injury. II. COMPONENTS OF THE REPORT A. INITIAL PAGE Address the report to the referring party(ies) or the DEU office noted on the Request for Summary Rating form. Report on factors influencing the complexity of the examination, being aware that complexity factors may be medical in nature or medical-legal, such as apportionment. Give an explanation if the face to face time of the examination was less than the required twenty minutes. Give names and professional description of any persons assisting with the report or performing diagnostic or consultative services. Note if there were communication difficulties (e.g. aphasia) or translation services required for the evaluation. B. s 46.1. Guidelines for the Evaluation of Foot and Ankle Disability. I. Introduction A. Basic Purpose of the Guidelines The purpose of these evaluation guidelines is to develop a more uniform method of evaluating foot and ankle injuries without diminishing the individual expertise of the participating evaluator. This method will allow involved parties (particularly the WCAB) to review evaluator's reports, which employ a more standardized format. B. General Approach The evaluator shall personally take the history from the injured worker and perform the examination. The evaluator may have an assistant make an initial outline of the injured worker's history or take excerpts from prior medical records, however the evaluator must review the excerpts and/or outline with the injured worker. Occupational and medical questionnaires may be useful to assist the injured worker in compiling the details of the injury prior to the consultation with the evaluator. Any discrepancies in the various sources of information should be identified and clarified by the evaluator. The injured worker shall at all times be evaluated in a compassionate and respectful manner. The evaluator will should introduce him/herself, and explain to the injured worker the purpose and scope of the evaluation. The evaluator must inform the injured worker of any significant medical findings, which could impact on his or her health. These findings may not be directly related to the work injury. II. Components of the Report A. Initial Page Address the report to the referring party(ies) or the DEU office noted on the Request for Summary Rating form. Report on the face to face time and factors influencing the complexity of the examination, being aware that complexity factors may be medical in nature or medical-legal, such as apportionment. Give names and professional description of any persons assisting with the report or performing diagnostic or consultative services. Note if there were communication difficulties (e.g. aphasia) or translation services required for the evaluation. B. History Medical records and history questionnaires shall be used only as an adjunct to the history as told by the patient to the physician. The physician shall personally take the history from the injured worker. Any discrepancies in the history between various sources must be identified and clarified. An appropriate history shall include: D. Work history, including previous and current jobs, and some description of previous, and current job duties. Review and comment on a formal job description if it is available for review. Particular attention for the foot and ankle is placed on requirements for standing, walking (over even or uneven surfaces), running, squatting, sitting, kneeling, climbing, jumping, hopping, balancing, lifting, carrying, pushing or pulling with the legs or feet and use of foot controls. This section is especially important, as the physician must extract sufficient history to assess the injured worker's pre-injury functional capacity for work activity. Determining the previous work capacity within the past several years best assesses this. Regular non-work activities can also be taken into account to determine previous functional levels. E. Description of how and when the injury occurred and the type of occupational exposure. F. Summary of the course of treatment for the injured worker since injury includes type of treatment and response to treatment to date. G. Current treatment including type and frequency. H. Description of pertinent past medical history including previous and or subsequent injuries or illnesses, and a description of any prior neurological or musculoskeletal disabilities particularly relating to the lower extremity. I. Pertinent other past medical history and other contributing medical, psychological, or social concerns. C. Current Complaints The physician shall outline in the patient's words, his or her current complaints. This shall include all parts affected by the injury or injuries claimed, the character (quality), severity, frequency, and any radiation of symptoms, and what activities or interventions precipitate, aggravate or reduce symptoms. Delineate existing associated signs and symptoms of the injury. NOTE: The patient's own description of symptoms shall be "translated" later by the physician into ratable language as defined by Packard Thurber. Any subjective complaints regarding work activity or other activities of daily living (ADL's) shall be outlined in this section. For the foot and ankle, any functional complaints in such as standing, walking (over even or uneven surfaces), running, squatting, sitting, kneeling, climbing, jumping, lifting, carrying, balancing, pushing or pulling with the legs or feet and the use of foot controls shall be listed in this section. The use of assistive devices (if any) for mobility such as a wheelchair, cane, or crutches, shall be elicited and described as to type and frequency of use, as well as the need and type of any orthotic or prosthetic devices and special shoes. D. Medical Records Reviewed In this section, the physician shall list all records reviewed in the preparation of the report. Extractions from those records may be listed in this section or summarized in the History section of the report. D. Physical Examination of the Foot and Ankle for Disability Evaluation (1) The physical examination shall include relevant description of body habitus, and any general observations such as a limp, obvious discomfort when standing, difficulty in transferring, etc. that may be helpful in determining previous or current functional capacity. Note any assistive devices, prosthetics, orthotics, or shoes that the patient uses and describe. (2) In all measurements or observations performed, if normal, the physician may simply state "normal". Describe tests rather than just use an acronym. (3) Inspection: The physician shall describe any skin abnormalities, surgical scars, obvious atrophy or skeletal deformities (e.g. angulation of healed fractures, varus or valgus joint deformity, or amputation). The injured parts of the foot or ankle shall be inspected for soft tissue swelling and dislocation. (1) Amputations shall be described anatomically. (1) Affected areas shall be palpated for tenderness. Any painful areas shall be reported. Any alterations of skin temperature or vascular status shall be noted. (6) Joint examination a. The physician shall assess the affected joints and compare them to the uninjured side. a. Joint effusion, enlargement, erythema, and instability shall be described if present. Pertinent clinical tests used in joint assessment (i.e. drawer signs, Thompson's sign, etc.) shall be described and noted as normal or abnormal. If there is an abnormal range of motion that is not secondary to the injury, give an explanation for this finding. b. Goniometric measurement is the accepted method of evaluation of range of motion for the foot and ankle. A description of goniometric methods of measurement and estimated normal values for the foot and ankle can be found in Packard Thurber, Evaluation of Industrial Disability, Second Edition, Oxford University Press. The physician shall measure active range of motion of all affected joints of the foot and ankle as compared to the uninjured side. Any abnormal, excessive, or limited range of motion or ankylosis shall be described. For bilateral injuries estimate the normal range of motion. Note whether the injured worker gave full effort on active range of motion and if there was any unexplained discrepancies in formally measured versus observed range of motion, or whether limitations in active range of motion was based on pain. If so, list arc range of motion precluded or inhibited by pain. If the measurement obtained were invalid based on lack of effort, so note. (7) Leg lengths shall be measured in inches from Anterior Superior Iliac Spine (ASIS) to medial malleolus and if appropriate, other methods of leg length measurement may be included. D. Gait and other functional assessment: Any abnormality of gait shall be described (propulsive vs. apropulsive, angle and base of gait, etc.). Evaluate patient's ability to squat, stand, kneel, heel and toe walk. (9) Neurological examination of the foot or ankle shall be performed for any complaints of weakness, sensory impairment or dysesthesias. This shall include assessment of: a. Motor examination i. Atrophy of specific muscles or muscle groups of the lower extremities or foot should be described. General muscle bulk is assessed by measurement s of the calves and thighs in inches. Circumferencial measurements of the foot and ankle should be recorded. Calf measurements are taken at the point of maximum circumference. Thigh circumferences are taken at the point one-third the distance from the upper pole of the patella to the umbilicus. ii. Muscle tone shall be described as increased, normal or decreased. i. Muscle strength shall be graded using a scale such as those found in Appendix A. Muscle weakness due to neurologic impairment shall be differentiated by the examiner from lack of effort due to pain, disuse or lack of effort due to other causes. In cases of questionable effort, muscle weakness due to neurologic deficit can generally be corroborated by appropriate electodiagnostic testing including needle EMG and a nerve conduction study performed by an appropriately qualified physician. b. Sensory examination shall include a screening of touch and pain sensation (pinprick) in pertinent foot, ankle and lower extremity dermatomes/peripheral nerve distributions and of joint proprioception of any involved joints. Any abnormalities shall be described fully and correlated with peripheral nerve or dermatomal pattern. If the pattern of sensory impairment is nonphysiological, this should be noted c. Deep tendon reflexes shall be obtained and graded as 0 (absent) to 4+ (hyperactive with clonus). Plantar responses and any other abnormal reflex responses shall be recorded. d. Coordination shall be assessed if this is a presenting complaint, or if there is suspicion of foot, ankle or lower extremity motor coordination impairment. In this case, finger to nose, heel to shin and gait should be described. (10) Screening exam of remainder of neurological or musculoskeletal system if there is any evidence of more widespread involvement. D. Diagnostic Studies in Lower Extremity Disability Evaluation (1) Order diagnostic studies only when the studies may alter the recommended plan or the evaluator's opinion regarding factors of disability. The evaluator must document the need for these additional studies. (2) List any diagnostic procedures performed, as well as the dates and the results of the procedures. Provide the name, specialty, qualifications and opinion of any consultants. (3) Methods of Assessment a. Clinical diagnosis of foot and ankle problems can usually be made on history and physical examination with the help of x-rays. b. In addition to an x-ray, testing may include: i. MRI ii. CT iii. Bone Scan iv. Arthrogram v. Use of mechanical devices to test strength and stability. vi. EMG/NCV testing is appropriate only if there is a suggestion of nerve damage or nerve compression. vii. Vascular studies are indicated only if there is associated vascular disruption/damage or a secondary vascular complication. viii. Blood Studies ix. Ultrasound x. Diagnostic, but not therapeutic, blooks y. There are other tests that may be performed with proper documentation of necessity: G. Diagnosis List the relevant diagnosis(es). When appropriate, state if the injury is right or left sided or bilateral. H. Opinions & Discussion State that the report represents your opinions and how those opinions were derived after carefully reviewing the forwarded medical information, the injured worker's subjective statements offered during consultation, and examination findings. I. Causation State an opinion as to whether the injury or illness that led to the disability arose out of the employment (AOE). J. Permanent and Stationary State whether the injured worker is permanent and stationary and reasons for that opinion. The term permanent and stationary means that the injured worker has reached maximal improvement or his condition has been stationary for a reasonable period of time. K. Temporary Disability If the injured worker is not permanent and stationary, describe the current work restrictions that might allow the worker to return to work immediately, any additional treatment and the anticipated length of time necessary to achieve permanent and stationary status. L. Factors of Disability The evaluator will describe the subjective and objective components of disability. Do not provide a "rating" but describe the medical information in such a way as to be used by raters, judges and other concerned parties. The following information shall be included: 1. Subjective Factors of Disability Translate the injured worker's symptoms into ratable language using the terminology found in section 9727 of title 8 of the California Code of Regulations, and reproduced here in Appendix B. Subjective factors are those that cannot be directly measured or observed, such as pain, stiffness, and paresthesia. It is important to note that this is the physician's assessment of residual symptoms and is based on the examination, the physician's experience with similar injuries and his/her expert medical opinion. It is not simply a catalog of an individual's complaints, as this might inaccurately inflate the disability rating if the complaints are not consistent with the physician's findings. Statements in this part of the report should be consistent with the nature of the injury and with the objective findings. Work restrictions based on subjective factors that are out of proportion to objective findings require specific explanation. The recommended description of subjective disability should include the activity which produces disabling symptoms; the intensity, frequency and duration of symptoms; a description of the activities that are precluded and those that can be performed with the symptoms; and the means necessary for relief. 2. Objective Factors of Disability Note those findings which can be measured, observed or demonstrated on testing. They include, but are not limited to: range of motion, strength, sensation, reflexes, amputation, anatomical measurements, disfigurement, and radiographic or other diagnostic results. Note if assistive devices, prosthetics, or orthotics are required and describe the device. Note if the device causes any limitation in motion. 3. Work Capacity Report work restrictions for the activities the injured worker was performing at the time of the injury and for potential activities in the open labor market. The evaluator will estimate the total or partial loss of the injured worker's pre-injury capacity to lift, walk, push, pull, climb, walk on uneven ground, squat, kneel, crouch, pivot, bear weight or other activities involving comparable physical strength. The best means is to describe the injured worker's loss of capacity, such as loss of one-quarter of his ability to lift. Use of job history and/or description as well as other activities of daily living to estimate the pre-injury capacity, should be noted in the report to substantiate the evaluator's opinion on loss. Be as specific as possible, incorporating the injured worker's history, the RU-90, the DEU Form 100, and a formal job analysis, if it is available. M. Apportionment State if apportionment is indicated and provide reasons for the statement. Indicate in the report whether apportionment is for a pre-existing condition under Labor Code section 4750, an underlying disease process under Labor Code section 4663 or a subsequent non-industrial injury under Labor Code section 4750.5. N. Further medical care Give your recommendation for current and future treatment. If the injured worker is currently receiving treatment, indicate whether the treatment is necessary to either improve or prevent deterioration of the current condition. If you believe that additional treatment is indicated to reach maximum improvement, you should explain the type of treatment, the reasons for the treatment, and the possible benefits of the treatment. O. Vocational rehabilitation If requested, state if the injured employee is medically qualified for vocational rehabilitation based on your review of the job analysis. P. Affirmations and signature The following paragraph must be included and signed and dated by the evaluator. The report must contain an original signature by the evaluator. "I declare under penalty of perjury that the information contained in this report and its attachments, if any, is true and correct to the best of my knowledge and belief, except as to information that I have indicated I received from others. As to that information, I declare under penalty of perjury that the information accurately describes the information provided to me and except as noted herein, that I believe it to be true." I have not violated Labor Code Section 139.3 and the contents of the report and bill are true and correct to the best of my knowledge. The foregoing declaration was signed in __________ __________County, California on _________________ (date). __________ Evaluator's Signature Note: Authority cited: Sections 139, 139.2, 4060, 4061 and 4062, Labor Code.

Appendix A Muscle Grading Chart Results may be reported using a verbal scale or a percentage loss of muscle strength as follows. In either case, the evaluator must still describe how a given loss of muscle strength affects the injured worker's capacity to perform work. Muscle Gradation Description 5-Normal 5-complete range of motion against gravity with full resistance 4-Good 4-complete range of motion against gravity with some resistance 3-Fair 3-complete range of motion against gravity 2-Poor 2-complete range of motion with gravity eliminated 1-Trace 1-reads evidence of slight contractility, no joint motion 0 (Zero) 0-no evidence of contractility Examples of Muscle Grading Charts Results may be reported using a verbal scale or a percentage loss of muscle strength as follows. In either case, the evaluator must still describe how a given loss of muscle strength affects the injured worker's capacity to perform work. Muscle Gradation Description 5-Normal 5-complete range of motion against gravity with full resistance 4-Good 4-complete range of motion against gravity with some resistance 3-Fair 3-complete range of motion against gravity 2-Poor 2-complete range of motion with gravity eliminated 1-Trace 1-reads evidence of slight contractility, no joint motion 0 (Zero) 0-no evidence of contractility Kendall Lovett Description 100 % Normal The ability to hold the test position against gravity and maximum 95 % Normal - pressure, or the ability to move the part into test position and hold against gravity and maximum pressure 90 % Good + Same as above except holding 80 % Good against moderate pressure. 70 % Good - Same as above except holding 60 % Fair + against minimum pressure. 50 % Fair The ability to hold the test position against gravity, or the ability to move the part into test position and hold against gravity. 40 % Fair - The gradual release from test position against gravity; or the ability to move the part toward test position against gravity almost to completion, or to completion with slight assistance or the ability to complete the arc of motion with gravity lessened. Kendall Lovett Description 30 % Poor + The ability to move the part through partial arc of motion with gravity lessened; moderate arc, 30% or poor +; small arc, 20% or poor. To avoid moving a patient into gravity-lessened position, these 20 % Poor grades may be estimated on the basis of the amount of assistance given during anti-gravity test movements: A 30% or poor + muscle requires moderate assistance, a 20% or poor muscle requires more assistance 10 % Poor - In muscles that can be seen or palpated, a feeble contraction may be felt in the muscle, or the tendon may become prominent during the 5 % Trace muscle contraction, but there is no visible movement of the part. 0 % Gone No contraction felt in the muscle. Appendix B Subjective disability should be described in terms of location, degree, frequency, and precipitating activity. Terms describing degree and frequency are taken to have the following meanings: Degree: Minimal or mild pain constitutes an annoyance, but causes no handicap in the performance of activity.

The method of measuring immunologic elements of disability shall be as set forth below in the "Guidelines for Immunologic Testing" as adopted by the Industrial Medical Council on March 17, 1994. STATE OF CALIFORNIA DEPARTMENT OF INDUSTRIAL RELATIONS INDUSTRIAL MEDICAL COUNCIL 395 Oyster Point Blvd., Ste. 102 South San Francisco, CA 94080 Tel:(650)737-2700 Fax:(650)737-2989 ADDRESS REPLY TO: P.O. Fox 8888 San Francisco, CA 94128-8888 Guidlines For Immunologic Testing Adopted March 17, 1994. Laboratory testing of immunologic function is appropriate and necessary in the evaluation of industrial injuries but only in selected cases. Immunologic function testing falls into four general categories: I. Allergy to a specific chemical agent. II. Allergy to common antigens from the general and home environment (e.g., pollens). III. Malfunction of the immune system unrelated to infection. IV. Specific infection. Category I: Allergy To A Specific Chemical Agent Testing shall be done only when: A. The worker has been exposed to a specific chemical at work known to cause hypersensitivity. B. The worker has sysmptoms or physical findings on examination that can be due to allergy to a chemical agent. C. The specific suspected chemical agents of interest has been identified. Testing shall not be done for chemical agents to which the worker has not been exposed. The purpose of Category I is to confirm that the worker is allergic and reactive to a specific chemical agent. The presence of a laboratory test showing reactivity does not in itself indicate physical disability unless there also are subjective symptoms and/or objective findings of physical impairment which are consistent with such reactivity. Many people have positive reactivity tests but do not have clinical disease. Testing methods must be for the specific chemical agent. They may be blood tests for antibodies, skin tests or special tests such as lymphocyte reacitivty to beryllium. Category II: Tendency To React To Common Allergens This testing is of very limited use: It is allowable only when the clinical findings (e.g., sneezing, nasal obstruction or wheezing) could be due to either workplace agent or non-industrial exposure. Testing may be of the blood (IgE, RAST) or of the skin (patch, scratch or intradermal). Category III: Testing Of Function Of The Immune System In unusual circumstances (e.g., occupational exposures to ionizing radiation or chemotherapeutic agents), direct clinically significant damage to the immune system may occur and be relevant to the assessment of occupationally related disability. Many chemical agents other than chemotherapeutic drugs have been shown to produce subtle effects on the immune system is research studies. However, such subtle effects do not cause work-related disablilty and cannot be the basis for laboratory testing. In the unusual circumstance in which the need for immune testing occurs, such testing shall involve some or all the following: A. Complete blood count B. Total serum immunoglobulin level and immunoglobulin electrophoresis C. Total lymphocyte count and counting of T and B lymphocytes, including subsets. Further testing of the immune system must be based on a strong clinical indication and must be supported by an explanation by the physician as to the need and purpose of the testing (which may be diagnostic or prognostic in nature but not for research pruposes). Under circumstances such as a severely emotionally stressful event or the taking of certain medications for an industrial illness or injury, an autoimmune disorder may be precipitated or aggravated. When symptoms and/ or physical findings suggestive of this occur, serological testing for autoimmune disorders is appropriate, but only when needed to confirm the diagnosis. Category IV: Specific infections Serologic and other immune system testing are allowable only when the physician-obtained history, physical examination, routine laboratory test results and/or medical records confirm or cause the physican to suspect certain infections that may be occupationally-related (e.g., viral hepatitis, valley fever and HIV infection). Testing may by specific for the infectious agent or may be nonspecific: A. Specific tests: 1. Antigen and antibody tests that currently are available for the various types of viral hepatitis (A, B, C and delta). 2. complement fixation titer for valley fever (coccidioidomycosis) to rule in or out active disseminated disease. 3. Elisa testing for an HIV infection. If positive, the results shall be confirmed with a Western Blot test. B. Nonspecific tests: 1. White blood cell and differential count. 2. Total lymphocyte count and counting of T and B lymphocytes, including subsets. Further testing of the immune system shall be based on strong clinical indications and shall be supported by an explanation by the physician of the need and purpose of the testing. SUMMARY: In the four selected categorical situations, immunological laboratory testing is appropriate only as described above. Such testing shall be performed in Workers' Compensation cases only if an abnormality would affect the determinaiton of compensability or clinical management. These conditions include detemination of disability status (temporary partial disability, temporary total disability, permanent partial disability and permanent total disability), specific work restrictions, causation of disability, apportionment, future medical treatment and the need for vocational rehabilitation.

Credit for the same distance learning program may be taken only once. (C) All distance learning materials shall bear a date of release and shall be updated every three years. The provider shall notify the Council in writing of the revision. (b) In addition to granting credit for attending a course or program which it gives, the Council may grant credit for: (1) Participating in a panel on the development or review of the QME competency examination. A physician may receive one hour credit for each hour of participation on a panel. The QME shall obtain documentation of participation from the test administrator for submission to the Council. (2) Instructing in a program given for QME credit by a provider accredited by the Council. The instructor may receive two hours of credit for each hour of instruction in an accredited provider's program or one hour of credit for each hour of participation on a panel. Credit for the same presentation may be taken only once during each calendar year. The QME shall submit documentation of participation from the program provider to the Council. (3) Attending a program which is accepted by the QME's licensing board for renewal of his or her professional license, provided the subject matter is directly related to California impairment evaluation or workers' compensation medical dispute evaluation. To request credit for this type of course, the QME must submit: (A) proof of attendance; (B) written material which describes the program content and program faculty; and (C) documentation that the program is for continuing education credit by the physician's licensing board. (4) Passing the QME competency examination. A QME may be granted six hours of continuing education credit for passing this examination for the purpose of receiving an initial appointment as a QME. (c) To apply to the Council for accreditation, a provider shall submit to the Council, at least 60 calendar days before any public advertisement of the applicant's program or course is made: (1) a completed form 118, in section 118 of these regulations. (2) A curriculum vitae for each proposed instructor or author (for paper-based programs). A proposed instructor or author shall have education and/or training and recent work experience relevant to the subject of his/her presentation. (3) The proposed promotional material for the program. (d) The Council shall accredit an applicant who meets the definition of a provider in Section 1(r); submits a completed, signed and dated application which demonstrates past experience in providing continuing education programs; and proposes a program which meets the requirements of section 55(c) or a course which meets the requirements of section 11.5(a) and (i). Proposed content for continuing education program credit must relate directly to disability evaluation or California workers' compensation-related medical dispute evaluation. No credit shall be recognized by the IMC for material solely discussing the business aspects of workers' compensation medical practice such as billing, coding and marketing. (e) The Council shall notify the applicant within 30 calendar days following the next scheduled council meeting after receipt of the application containing all the information listed in Section 55(c) whether that provider has been accredited for a two year period. Incomplete applications will be returned to the applicant. (f) A provider that has been accredited by the Council will be given a number which must be displayed on any public advertisements of QME continuing education programs for that provider with the statement "Accredited by the California Industrial Medical Council for Qualified Medical Evaluator continuing education. Physicians may report up to ___ hours of credit for QME reappointment." (g) On or before the date the program is first presented or distributed, the provider shall submit the program syllabus (all program handouts) to the Council. Each distance learning program shall also submit one copy of the examinations and one copy of the audio/video tapes, computer program or each issue of the journal or newsletter for which credit is to be granted. (h) A provider may offer different QME continuing education programs during the two-year accreditation period provided the subject matter is in disability evaluation or workers' compensation related medical dispute resolution. The provider shall send the Council the program outlined and faculty for each new program at least 45 days prior to the date of presentation of the new program. The Council may require submission of program syllabi. The Council may require changes in the program based on its review of the program outline, program syllabi, promotional material or faculty if the IMC finds that any aspect of the program is not in compliance with these regulations. (i) Promotional materials for a program must state the provider's educational objectives; the professional qualifications of program faculty (at least all relevant professional degrees); the content of program activities; the maximum number of credit hours to be granted; and the intended audience.

The guidelines for determining appropriate sanctions for physicians licensed as Qualified Medical Evaluators shall be set forth in the Sanction Guidelines as adopted by the Industrial Medical Council on October 21, 1999. 65. Sanction Guidelines for Qualified Medical Evaluators Part One I. Overview The purpose of these guidelines is to provide a framework of the Industrial Medical Council (IMC) disciplinary process for those affected by it - Qualified Medical Evaluators, the IMC, administrative law judges with the Office of Administrative Hearings, licensing boards and other interested parties. These guidelines are not intended to be an exhaustive list of violations or disciplinary actions that the IMC may consider against any QME. Any violation of statutory or administrative duties may constitute grounds for discipline under these guidelines. The IMC believes that education is the most effective course of action in resolving less serious regulatory violations. These guidelines also set out the parameters for discipline for misconduct considered serious. The IMC recognizes the need to promulgate uniform guidelines for particular violations in order to establish consistency in imposing disciplinary sanctions for similar offenses. The IMC also recognizes that mitigating or aggravating circumstances in a specific case may necessitate variance from these guidelines. In the event of a hearing, if an administrative law judge finds that the circumstances of a particular case are not adequately addressed in these guidelines, the IMC may request that the administrative law judge include in the proposed decision an explanation of the recommended sanction and/or terms of probation, so those circumstances are better understood by the IMC during its review of the case for ultimate action. II. Factors to be Considered in Determining Disciplinary Penalties In cases of violations of Labor Code sections 139.2(k) and 139.2(m) and/or section 60 of Title 8 of the California Code of Regulations, the IMC may impose discipline, up to and including suspension or termination, upon any physician certified by the IMC as a Qualified Medical Evaluator. In determining the level of the penalty to be imposed in a given case, the following factors (8 CCR s 61) shall be considered: (1) the seriousness of the violation including actual or potential harm to the public and any mitigating or rehabilitation evidence; (2) whether or not a violation is an isolated incident or part of a pattern of behavior indicative of a disregard for the QME rules; e.g. (prior warnings of record; number and/or variety of current violations, time passed since the act(s) or offense(s)); (3) whether or not a violation is intentional as opposed to negligent; (4) whether or not there is a history of previous violations cited under this section or by another court or tribunal (e.g.: prior disciplinary record, including level of compliance with disciplinary orders, compliance with terms of any criminal sentence, overall criminal record); and (5) whether or not further education or training would be beneficial. III. Mitigating Evidence A respondent may present evidence at a hearing or in the settlement process and shall have the burden of demonstrating mitigating circumstances and/or any rehabilitative or corrective measures he or she has taken. The IMC does not intend, by the following references to written statements, letters, and reports, to waive any evidentiary objections to the form of such evidence. The following are examples of appropriate evidence a respondent may submit to demonstrate his/her rehabilitative efforts and competency: a. Recent, dated written statements from persons in positions of authority who have on-the-job knowledge of the respondent's current competence in the practice of his or her specialty. Each statement should include the period of time and capacity in which the person worked with the respondent and should be signed under penalty of perjury. All letters will be subject to verification by IMC staff. b. Recent, dated letters from counselors regarding the respondent's participation in a rehabilitation or recovery program, where appropriate. These should include at least a description and requirements of the program, a psychiatric diagnosis and current state of recovery and the psychiatrist's/psychologist's basis for determining need for rehabilitation. c. Recent, dated letters describing respondent's participation in support groups, (e. g. Alcoholics Anonymous, Narcotics Anonymous, Professional Support Groups, etc.), where appropriate. d. Recent, dated laboratory analyses or drug screen reports, where appropriate. e. Recent, dated performance evaluation(s) from the respondent's employer(s). f. Recent, dated physical examination or assessment report by a licensed physician, if appropriate. In the above examples, the mitigating circumstances and/or rehabilitative efforts shall be detailed in any proposed decision or any transmittal memorandum accompanying a proposed stipulation. IV. Terms of Probation If probation is imposed as part of a disciplinary action, the probation shall include: (1) Standard conditions, which will apply in all cases; and may include (2) Optional conditions, which will vary according to the nature of the offense(s) in the particular case.

Respondent shall execute a written release authorizing the designated third party(s) to divulge any information that the IMC may request during interviews by the probation monitor on a periodic basis. 24. Psychiatric Evaluation Within thirty (30) days of the effective date of this decision, and on a periodic basis thereafter as may be required by the IMC or its designee, Respondent shall undergo a psychiatric evaluation by a psychiatrist/psychologist appointed by the IMC. The appointed evaluator shall furnish a report to the IMC or its designee. If Respondent is required by the IMC or its designee to undergo psychiatric treatment, Respondent shall within thirty (30) days of the requirement notice, submit to the IMC for its prior approval the name and qualifications of a psychotherapist of Respondent's choice. Upon approval of the treating psychotherapist, Respondent shall undergo and continue psychiatric treatment until further notice from the IMC. Respondent shall have the treating psychotherapist submit quarterly status reports to the IMC. (Optional) Respondent shall not perform any function as a Qualified Medical Evaluator or an Agreed Medical Evaluator until notified by the IMC of its determination that Respondent is mentally fit to resume such forensic practice. 25. Psychiatric Treatment Within sixty (60) days of the effective date of this decision, Respondent shall submit to the IMC for its prior approval the name and qualifications of a psychotherapist of Respondent's choice. Upon approval, Respondent shall undergo and continue treatment until his or her treating psychotherapist (i.e. psychiatrist, psychologist, other licensed mental health practitioner) deems that no further psychiatric treatment is necessary. Respondent shall have the treating psychotherapist submit quarterly status reports to the IMC. The IMC may require Respondent to undergo psychiatric evaluations by an IMC-appointed psychiatrist/psychologist. (Note: This condition is for those cases where the evidence demonstrated that the respondent has had impairment [i.e. impairment by mental illness, alcohol abuse and drug self abuse] related to the violations but is not at present a danger to his/her patients.) 26. Medical Evaluation Within thirty (30) days of the effective date of this decision, and on a periodic basis thereafter as may be required by the IMC or its designee, Respondent shall undergo a medical evaluation by an IMC appointed physician who shall furnish a medical report to the IMC or its designee.

Treatment Guideline for Low Back Problems. The Industrial Medical Council recommends treatment of industrial injury to the low back, consistent with the "Treatment Guideline for Low Back Problems," as adopted by the Industrial Medical Council on April 17, 1997 as set forth below. TREATMENT GUIDELINES FOR LOW BACK PROBLEMS Introduction Low back problems are common among workers. In the majority of injured workers with low back problems, recovery occurs within the first month of symptoms. Those who have not improved at the end of one month of treatment may need further diagnostic evaluation and consideration of other treatment options. Management of low back problems in injured workers includes consideration of environmental and personal factors which may be causing or aggravating the problem, as well as providing appropriate treatment that leads to a return to productive work. Scope of the Guideline This guideline deals with the assessment and treatment of common low back problems in working age people. Initial assessment to rule out uncommon low back problems is discussed, but definite diagnosis and treatment of uncommon disorders is beyond the scope of this guideline. This guideline does not deal with legal issues of causation or work-relatedness. Treatment guidelines are designed to assist providers by offering an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted practices for the assessment and treatment of low back problems. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed with these types of industrial conditions. Due to many factors which must be considered when providing quality care, health care providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. These guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all patients with a particular condition. It is understood that some patients will not fit the clinical conditions contemplated by a guideline. This includes those patients demonstrating "Red Flag" concerns described in the guideline. Symptom duration is classified as acute (< one month), subacute (one to three months), and chronic (> three months). If an injured worker experiences more than one recurrence of low back pain in a year, except in cases of a new injury, it should not be classified and treated as an acute back problem. In this case, it is considered a chronic recurrent low back problem, and secondary assessment and treatment methods should be utilized along with an emphasis on active therapy and prevention strategies. Chronic low back problems are outside the scope of this guideline. For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with the Official Medical Fee Schedule. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document no later than six months from the date of the injury, whether further treatment is warranted and whether the injured worker has any significant subjective and objective findings of the condition still not having plateaued. 1.0 Initial Assessment of Low Back Problems 1.1 Purpose The purpose of the initial assessment is to establish a working diagnosis and assign the injured worker into one of five initial clinical categories of low back problems: 1) Conditions involving the bony spinovertebral axis such as cancer, infection or fracture; 2) Intraspinal pathology involving the neuraxis such as cauda equina syndrome or radiculopathy; 3) Arthritic or inflammatory conditions; 4) Mechanical conditions; or 5) Referred low back pain due to viscerogenic and/or other causes. In addition, the initial assessment looks for (and documents for the chart) other factors which might have an impact upon an injured worker's symptoms and/or response to treatment (e.g., work, personal, psychosocial, and economic factors). 1.2 Appropriate Initial Assessment Methods 1.2.1 History and physical The history and physical examination are the bases upon which any assessment and treatment decisions are to be made. Decisions about diagnostic imaging, laboratory testing, and specialist referral should be guided by the clinical features of the history and exam. Only a small minority of injured workers will require further diagnostic testing after the initial history and physical. On the history, document the characteristics of pain (type, location, duration, severity, radiation), associated symptoms, precipitating factors, positions and activities that aggravate or relieve the symptoms, as well as its impact on function at home and work. Information concerning previous back injuries, diagnostic and treatment procedures, and response to previous therapies (including home treatments and use of appliances) should be obtained. The use of a pain drawing and/or pain scale (e.g., Visual Analog Scale) may assist in the evaluation of the location, characteristics, and severity of pain, and may be utilized in the assessment of treatment response. (One example of a pain drawing and pain scale appears in Appendix 7.1.) The relationship of the symptoms to performance of specific activities should be sought (e.g., work tasks and ergonomic factors, sitting, walking, driving, coughing, hobbies, recreational activities, etc.). In addition, ask key questions pertinent to serious spinal, intraspinal or viscerogenic conditions [see below]). The initial history should also document relevant past medical and surgical history, occupational history, social (including hobbies, recreational activities, and the use of tobacco, alcohol and other drugs), and any relevant psychosocial issues such as financial, family, or workplace difficulties. A thorough physical examination that is based upon the appropriate history and presentation of the patient is expected. The examination includes, but is not limited to, general appearance, visual inspection and palpation, manual testing of range of motion, vascular and neurologic inspection. A focused neurologic exam that includes reflexes, strength and sensation testing in the lower extremities should be performed. Bilateral supine and seated straight leg raising is also recommended during the initial evaluation. Examination of the hip joint can help exclude referred back or leg pain from an abnormal joint. Although most patients have localized, non radiating pain and/or limited range of motion, these findings are non specific for most back problems. Limited spinal motion may be useful for planning and monitoring response to treatment and for developing appropriate work restrictions. 1.2.1.1 Conditions involving the bony spinovertebral axis such as cancer, infection or fracture Certain key findings on the medical history and physical examination may raise suspicion of a possible serious underlying condition of the spine which requires immediate diagnosis and prompt treatment, including appropriate referral for specialty consultation. The following serious underlying conditions of the spine are suggested by, but not limited to, the "Red Flags" listed below: For cancer or infection: age greater than 50 years, history of prior cancer, unexplained weight loss, back pain not improved with rest, fever, immunosuppression, intravenous drug use, history of urinary infection and/or incapacitating pain. For spinal fracture: history of significant trauma (e.g., motor vehicle accident or fall from height), age greater than 60, prolonged use of corticosteroids, alcohol or substance abuse. Injured workers with clinical findings that suggest underlying disease may require further studies, such as laboratory tests, x-rays, or specialized tests to evaluate for these conditions. The provider should clearly document the need for any additional tests for other serious pathologies during the initial assessment. Other pathologies should be ruled out. 1.2.1.2 Referred low back pain due to viscerogenic and/or other causes Referred pain from visceral diseases or other musculoskeletal disorders unrelated to the lumbar spine may be distinguished by a careful history and physical examination. A history of urinary tract, abdominal or pelvic symptoms suggests visceral disease. Abdominal and pelvic disorders which may cause low back pain include abdominal aortic aneurysm, pyelonephritis, nephrolithiasis, gynecological problems, prostatitis, pancreatitis, and other gastrointestinal conditions. Examination of the hip and sacroiliac joints may reveal findings consistent with a localized joint or muscle problem. 1.2.1.3 Arthritic or inflammatory conditions Inflammatory arthritides of the spine that can cause back symptoms include ankylosing spondylitis and other rare spondyloarthropathies. A suspicion of these and other related conditions should suggest a referral to the appropriate specialist for further evaluation. Work-up of these conditions is not discussed in this guideline, but should be guided by the clinical findings and suspicion of a systemic illness. 1.2.1.4 Distinguish between mechanical conditions and radiculopathy or other neurological conditions For the purpose of determining the appropriate management of low back problems and estimating prognosis, it is helpful to classify injured workers into diagnostic categories, as well as to consider symptom duration. Most injured workers can be separated into diagnostic categories based on the location and characteristics of their symptoms and the clinical findings. 1.2.1.4.1 The symptoms of mechanical low back conditions are predominantly low back pain, with possible referral of pain to the buttock and/or leg above the knee in a non-dermatomal pattern. 1.2.1.4.2 Radiculopathy or other neurological conditions result from spinal or intraspinal pathology involving one or more nerve roots. Presenting symptoms are related to specific nerve root(s) and type of pathology and may include pain, alteration in sensation, loss of strength, and altered reflexes in various combinations. 1.2.1.4.3 Cauda equina syndrome results from injury to multiple lumbosacral nerve roots. It may present with bowel and/or bladder dysfunction, saddle hypesthesia or anesthesia. This serious condition is a red flag requiring immediate referral to an appropriate specialist. 1.2.1.5 Documentation of other relevant factors A detailed work history should be obtained, including a description of current job duties, and the relationship of symptoms to performance of job tasks. Psychological work factors that are known to increase the reporting of a back injury and lead to prolonged symptoms and disability include job monotony and job dissatisfaction. If psychological distress is suspected from the history, pain drawing, and/or the physical examination such as the presence of several "non-organic" physical signs (non anatomic or superficial tenderness, inconsistent response between supine vs. seated straight leg raising, pain on simulated axial loading or spine rotation, over reaction, and regional sensory and motor disturbances), the injured worker may be at risk for a delayed recovery or poor response to any surgical procedure. The medical and social history may help the provider evaluate for other risks of delayed recovery and plan therapy accordingly. A history of previous back injuries or surgery, failed previous treatments, prolonged or contentious litigation or disability claims, family or financial problems, or secondary gain may affect treatment response and prolong disability. Chronic pain, depression, and alcohol or substance abuse may prolong disability and influence the choices for therapy. Recreational and other non work activities which might contribute to low back problems must also be considered in the evaluation and management of low back problems. 1.2.2 Laboratory studies Laboratory tests should not be ordered routinely in the initial assessment unless an underlying illness is suspected. If the history, age, or examination suggests cancer, infection, inflammatory arthritis (such as ankylosing spondylitis), metabolic-endocrine disorders or visceral disease, then appropriate laboratory tests may be indicated. The physician must provide a clear rationale of the indications for the tests ordered. 1.2.3 Diagnostic imaging Plain X-Rays The most commonly used x-ray views of the lumbar spine (the standard anteroposterior and lateral views) permit assessment of lumbar alignment, comparison of vertebral body and disc space size, assessment of bone density and architecture, and gross evaluation of soft tissue structures. Oblique views of the lumbar spine are used in the detection of unilateral or bilateral spondylolysis. Other special views include sacroiliac views to evaluate possible ankylosing spondylitis. The diagnostic objective of x-rays is to reveal structural abnormalities associated with back symptoms. Plain x-rays are not recommended for routine evaluation of patients with acute low back problems within the first month of symptoms unless a red flag is noted on the clinical examination (such as specified below). Plain x-rays of the lumbar spine are recommended for ruling out fractures in patients with acute low back problems when any of the following red flags are present: recent significant trauma (any age), recent mild trauma (patient over age 50), history of prolonged steroid use, osteoporosis, patient over age 60. Plain x-rays in combination with clinically appropriate laboratory studies may be useful for ruling out tumor or infection in patients with acute low back problems when any of the following red flags are present: prior cancer or recent infection, fever over 100 degrees F, IV drug abuse, prolonged steroid use, low back pain worse with rest, unexplained weight loss. In the presence of red flags, especially for tumor or infection, the use of other imaging studies such as bone scan, CT, or MRI may be clinically indicated even if plain x-rays are negative. The routine use of oblique views on plain lumbar x-rays is not recommended in light of the increased radiation exposure. 1.2.4 Ergonomic evaluation Clinical indications: Work history, job analysis/description, or workplace inspection may be useful to identify physical work factors contributing to the development or exacerbation of low back problems, which prevent return to usual work. A worksite evaluation with the affected injured worker should be performed by a professional trained in these types of evaluations. 1.3 Inappropriate Initial Assessment Methods All of the following assessment methods have been determined inappropriate during the initial phase of assessment. (All are Appropriateness level 1.) Routine use of: 1.3.1 Laboratory studies 1.3.2 Lumbar x-rays 1.3.3 CT, MRI, myelography, CT-myelography, and bone scan 1.3.4 Discography 1.3.5 Electromyography (EMG) 1.3.6 Computerized strength and range of motion testing Computerized testing of strength and range of motion is not recommended in the initial assessment of acute low back problems. 2.0 Initial Treatment of Low Back Problems 2.1 Purpose The purpose of the initial treatment of low back problems is to relieve pain and suffering and to restore functional capacity. The goal is to allow the injured worker to resume necessary activities, including return to modified or full work according to the favorable natural history for low back problems. Injured workers with radiculopathy or other neurological conditions may require more aggressive management and closer monitoring for further neurologic deterioration that may require additional diagnostic testing with possible surgery. Treatment may include: 1) education about back problems and their prevention; 2) activity and environmental modifications; 3) exercise; 4) medication; and/or 5) physical treatments as delineated later in this section. This guideline does not address treatment for spinal conditions of cancer, infection, fracture, cauda equina syndrome, arthritic or inflammatory conditions, viscerogenic back symptoms or chronic low back problems. 2.2 Appropriate Initial Treatment Methods 2.2.1 Education 2.2.1.1 General information Appropriateness level 4 Education is the most effective method of reducing the injured worker's concerns about persistent pain problems. Accurate information concerning connective soft tissue injury and repair, including expectations for both rapid recovery and recurrences, should be provided to allay the injured worker's fear. Patients should be taught principles related to pertinent anatomy, proper back mechanics, postural information, and safe work methods. Safe and reasonable modifications of work, home, and recreational activities should be given. Instructions for self-management of symptoms and lifestyle modifications should also be provided (e.g., use of cold or heat therapy at home, medications, exercises, rest periods). Reassurance about the benign nature of most low back problems and its compatibility with various activities should be given. A collaborative partnership among the physician, employer and injured worker is an essential component of any plan to return the injured employee to work. Specific functional goals, including home and work activities, time frame for expected improvements, and return to work should be given by the provider to the injured worker. Effectiveness and risks of commonly available diagnostic and treatment measures should be considered if symptoms persist and should be discussed with the patient. Education should be provided by the treating provider and may be supplemented by a physical or occupational therapist as part of a referral for flexibility and strengthening exercise training (see below). 2.2.1.2 Back education program Appropriateness level 3 A back educational program that promotes exercise as a rehabilitation and prevention method is recommended for an injured worker with low back problems. 2.2.2 Activity and environmental modifications 2.2.2.1 Work restrictions Appropriateness level 4 Modifications of activities including specific work restrictions that are based on the injured worker's job requirements and clinical status, are acceptable if functional limitations do not allow continuation of regular work duties. Complete work cessation should be avoided, if possible, through the use of modified duty. Written work restrictions should be as specific as possible, and it may be necessary to contact the employer to discuss alternative work within the prescribed restrictions. Injured workers with work restrictions should be re-evaluated within two weeks for determination of work status, response to treatment, and for making appropriate decisions concerning progression to full activities. 2.2.2.2 Bed rest Appropriateness level 4 The majority of injured workers with low back pain will not require bed rest. Short-term continuous bed rest may be appropriate for up to two days. Bed rest for more than four days may lead to debilitation and is not recommended for treating low back problems. A gradual return to normal activities is more effective than prolonged bed rest for treating low back problems. 2.2.2.3 Environmental/job modification Appropriateness level 3 Environmental modifications including engineering (e.g., work station adjustment) and administrative controls (e.g., job rotation) to limit or eliminate work activities that might lead to or aggravate back problems should be considered early on for symptomatic workers who have work-related risk factors for low back problems. 2.2.3 Exercise Appropriateness level 4 2.2.3.1 Rehabilitative exercise recommendations Up to 12 visits for rehabilitative exercise may be implemented in the first month. A step-wise program using exercise goals that are gradually increased over time is appropriate in uncomplicated cases of most low back problems. Aerobic (walking, biking, swimming, or similar activities) and stretching exercises can begin early on to increase mobility. Progressive strengthening exercises for abdominal and back muscles may promote recovery and prevent prolonged disability due to deconditioning. Adequate instruction in exercises and positioning may require supervision by a provider. An active progressive exercise program designed to achieve or maintain an increase in range of motion and strength should be promoted as the best method of limiting recurrences of low back problems. The exercise program should be included in the treatment plan and/or referenced in the progress reports. The rehabilitative exercise visits shall be limited to a maximum of three times per week in the initial phase, with emphasis placed on home exercise. 2.2.3.2 Referral for physical treatment Appropriateness level 3 Referral for physical treatment may be appropriate within the first 30 days. 2.2.4 Medications 2.2.4.1 Acetaminophen Appropriateness level 4 Acetaminophen, a non-narcotic analgesic, has commonly been regarded as having an analgesic effect, but little or no known anti-inflammatory mechanism. The therapeutic objective for its use in acute low back problems is pain relief. Acetaminophen is reasonably safe and is acceptable for treating patients with acute low back problems. 2.2.4.2 Non-steroidal anti-inflammatory drugs (NSAIDs) Appropriateness level 4 NSAIDs are a class of medications, including aspirin, ibuprofen, indomethacin, and other medications. They have anti-inflammatory and analgesic properties as well as being prostaglandin inhibitors. The therapeutic objective of NSAIDs in treating acute low back problems is to decrease pain, presumably by reducing inflammation and promoting healing. NSAIDs, including aspirin, are acceptable for treating patients with acute low back problems but have a number of potential side effects. The most frequent complication is gastrointestinal irritation. The decision to use these medications can be guided by comorbidity, side effects, cost, and patient and provider preference. 2.2.4.3 Muscle relaxants Appropriateness level 3 Muscle relaxants are an option in the treatment of patients with acute low back problems. While probably more effective than a placebo, muscle relaxants have not been shown to be more effective than NSAIDs. No additional benefit is gained by using muscle relaxant in combination with NSAIDs over using NSAIDs alone. Muscle relaxants have potential side effects, including drowsiness in up to 30 percent of patients. When considering the optional use of a muscle relaxant, the clinician should balance the potential for drowsiness against a patient's intolerance of other agents. 2.2.4.4. Oral corticosteroids Appropriateness level 2 Oral steroids are used by some clinicians in the treatment of patients with acute low back problems. The therapeutic objective is to reduce inflammation in an attempt to promote healing and reduce pain. However, oral steroids are not recommended for the treatment of acute low back pain without radiculopathy. 2.2.4.5 Opioid Analgesics Appropriateness level 3 Oral opioid analgesics commonly given to patients with acute low back problems include morphine derivatives (opioids) and synthetic opioids. The therapeutic objective in treating low back problems is temporary pain relief. When used only for a time-limited course, opioid analgesics are an option in the management of patients with acute low back problems. The decision to use opioids should be guided by consideration of their potential complications relative to other options. Routine prescription of opioids is not recommended and when prescribed for severe pain, should be limited in duration and quantity. 2.2.5 Physical treatments Appropriateness level 4 2.2.5.1 Manual medicine, manipulative techniques, manual therapy/ mobilization include treatments performed by a physician or another appropriately licensed health care provider as defined by their scope of practice. 2.2.5.2 Other physical modalities Appropriateness level 3 Active treatments such as manual medicine/therapy may be combined with passive modalities, including but not limited to iontophoresis, phonophoresis, electrical stimulation, ultrasound, diathermy, traction, and other physical agents, during the first four weeks of treatment. These passive modalities should not be used as the sole form of treatment. They shall be combined with an active treatment program that emphasizes progressive exercises. 2.2.5.3 Frequency of physical treatment methods Appropriateness level 3 The frequency of the physical treatments listed above within the initial four weeks of treatment may be up to 12 visits in the first month. 2.2.5.4 Transcutaneous Electrical Nerve Stimulation (TENS) Appropriateness level 2 TENS may be useful for management of low back problems. If no functional and symptomatic benefit has been demonstrated after two weeks, treatment should be discontinued. 2.2.5.5 Acupuncture Appropriateness level 2 Acupuncture may be useful to relieve acute low back pain. The frequency of acupuncture treatments within the initial four weeks of treatment may be up to three times per week for four weeks, or up to twelve office visits. During this initial treatment, if there is not substantial improvement, in a maximum of 12 treatments, the patient is to be re-evaluated by a more extensive physical examination, laboratory testing, imaging or referral to another physician. 2.2.5.6 Epidural Steroid Injections Appropriateness level 2 An epidural steroid injection may be helpful for reducing tissue inflammation and short-term pain relief in a patient with an acute radicular low back problem who is unable to participate in an active treatment program because of severe leg pain and/or neuromotor deficit. If successful, a progressive active treatment program should be implemented with the goal of avoiding prolonged disability and possible surgical intervention. 2.2.5.7 Lumbar supports (e.g., corsets, support belts, braces) Appropriateness level 2 Immobilization with lumbar supports may provide symptomatic relief of pain and movement reduction in cases of severe acute low back problems. The injured worker should be advised of the potential harm from using a lumbar support for a greater period of time than that prescribed. 2.2.6 Hospitalization for non-surgical treatment Appropriateness level 2 Hospitalization is rarely necessary for the non-surgical management of severe low back pain. 2.2.7 Myofascial and trigger point injections Appropriateness level 2 Up to three trials of injection therapy within the first 30 days may be helpful for short term pain relief in patients with mechanical back conditions. Trigger point and myofascial injections are not for use as the exclusive method of treatment. 2.3 Case Management Appropriateness level 4 An adequate re-evaluation of the problem, with determination of treatment effectiveness and patient compliance, should be performed at appropriate intervals during the first 30 days of treatment. 2.4. Inappropriate Initial Treatments The following initial treatment methods are inappropriate in the initial treatment phase: (All are Appropriateness level 1.) 2.4.1 Surgical treatments Except for those further conditions cited earlier as 'red flags' relevant to intraspinal pathology such as cauda equina syndrome or radiculopathy, surgery for acute radicular pain within the first 30 days is usually not indicated. Surgical treatment is rarely, if ever, indicated for low back pain without radicular symptoms. 2.4.2 Exclusive use of physical modalities 2.4.3 Biofeedback 2.4.4 Implantable spinal techniques such as infusion pumps or stimulators 2.4.5 Back school A formal back school is usually not appropriate for an injured worker with acute low back problems. 2.4.6 Facet injections 3.0 Secondary Assessment of Low Back Problems 3.1 Purpose The purpose of secondary assessment is to determine the reason for delayed recovery in a patient who has not symptomatically or functionally improved after one month of appropriate treatment (i.e., progressed to a subacute low back problem). The first step in secondary assessment is a re-evaluation with assignment of the patient into one of the five clinical categories: 1) Conditions involving the bony spinovertebral axis such as cancer, infection or fracture; 2) Intraspinal pathology involving the neuraxis such as cauda equina syndrome or radiculopathy; 3) Arthritic or inflammatory conditions; 4) Mechanical conditions; or 5) Referred low back pain due to viscerogenic and/or other causes. Depending on the findings, diagnostic evaluation during the subacute phase (one to three months) may include diagnostic imaging, laboratory tests, bone scan, electrophysiologic tests, functional capacity testing, ergonomic evaluation and/or psychological testing. The clinical indications for each of these diagnostic methods is given below. Referral for consultation is appropriate for problems of delayed recovery or questions about diagnosis. Referral may be made to appropriate physician specialists. 3.2 Appropriate Secondary Assessment Methods 3.2.1 Plain film x-rays (AP and lateral views) Clinical indications: Persistent low back problems and/or suspicion of systemic disease, cancer, infection, inflammatory arthritis, fracture or spondylolisthesis. The routine use of oblique or special views on plain lumbar x-rays is not recommended in light of the increased radiation exposure. 3.2.2 Specialized imaging tests (CT, MRI) Clinical indications: 3.2.2.1 Findings that suggest lumbar nerve root compromise (radiculopathy from herniated disc and/or spinal stenosis) or a severe or progressive neurologic deficit has occurred. These studies are most suitable when surgery or epidural steroid injections are being considered and/or when the injured worker has failed an appropriate course of treatment. 3.2.2.2 Findings that suggest tumor or infection. 3.2.2.3 Findings that suggest a fracture and lumbar x-rays are inconclusive. 3.2.3 Other specialized imaging tests (myelography and CT- myelography) Clinical indications: When imaging tests (CT, MRI) are inconclusive, contradictory or contraindicated, other specialized imaging tests, such as myelography and CT-myelography, are warranted. These studies are invasive and should only be ordered in special situations. 3.2.4 Bone scan Clinical indications: Findings on history, exam, lab or other imaging studies are suggestive for but not limited to tumor, infection, fracture and arthritis. Bone scans demonstrate abnormal metabolic activity and are not diagnostic for these conditions. 3.2.5 Laboratory testing Clinical indications: As deemed appropriate by the reassessment. 3.2.6 Needle electromyography/nerve conduction study (EMG/NCS) Clinical indications: Diagnosis of lumbosacral radiculopathy can usually be made based upon the neurologic examination. EMG/NCS may occasionally be helpful for evaluating suspected nerve root dysfunction, peripheral neuropathy, or peripheral nerve entrapment when the findings on the exam are equivocal or confusing. They may be useful preoperatively to confirm a radiculopathy and may be of some assistance in determining the location and severity of nerve root injury. 3.2.7 Functional capacity testing Clinical indications: The injured worker's perception of his or her capabilities might be inaccurate, or there is an issue about ability to do a specific job. Comprehensive and objective measurements and tests that are specific to the patient's condition and the functional requirements for return to work may be performed. Functional capacity testing is performed to determine the injured worker's physical capacities. This in correlation with the physical findings may be used to determine the injured worker's ability to return to work. 3.2.8 Ergonomic evaluation Clinical indications: Work history, job analysis/description, or workplace inspection may be useful to identify physical work factors contributing to the development or exacerbation of low back problems that can prevent return to usual work. A worksite evaluation with the affected injured worker should be performed by a professional trained in these types of evaluations. 3.2.9 Psychiatric evaluation and/or appropriate psychological testing Clinical indications: Findings on history and exam that suggest that psychosocial factors (e.g. stress, job dissatisfaction, depression, substance abuse, symptom magnification) may be contributing to delayed recovery, noncompliance or lack of response to appropriate treatment in subacute and chronic low back problems. If an injured worker is at risk for delayed recovery, a psychiatric evaluation and/or appropriate psychological testing may be helpful for determining if significant psychological or personality factors are contributing to the disability. The presence of several "non organic" physical signs may also identify patients who need further psychological testing and evaluation. These patients may need specific behavioral or psychiatric treatment. Psychological and personality evaluations may be utilized preoperatively in a patient who is being considered for surgical treatment to assist in selection and planning whether behavioral intervention is necessary. 3.2.10 Somatosensory evoked potentials (SEP) Clinical indications: SEP may be helpful in evaluation of neurological involvement in conditions such as spinal stenosis or myelopathy. 3.3 Inappropriate Secondary Assessment Methods (All Appropriateness level 1) The following methods have been determined inappropriate for secondary assessment: 3.3.1 Discography 3.3.2 Surface EMG 3.3.3 Diagnostic blocks and injections including facet joint injections 3.3.4 Computerized strength and range of motion testing 4.0 Secondary Treatment of Low Back Problems 4.1 Purpose The purpose of secondary treatment is to provide appropriate symptomatic relief for the injured worker with low back problems while continuing to intensify efforts in active treatments, such as exercise. The aim of secondary treatment is to prevent progressive deconditioning and permanent disability, while promoting return to full work for those who are either off work or on modified duty. Treatment is based on the findings of the diagnostic re-evaluation at four weeks. This phase of treatment may be extended up to two months beyond the initial phase of treatment. 4.2 Appropriate Secondary Treatment Methods 4.2.1 Rehabilitative exercise recommendations Appropriateness level 4 A step-wise program using exercise goals that are gradually increased over time is appropriate in uncomplicated cases of most low back problems. Aerobic (walking, biking, swimming, or similar activities) and stretching exercises can begin early on to increase mobility. Progressive strengthening exercises for abdominal and back muscles may promote recovery and prevent prolonged disability due to deconditioning. Adequate instruction in exercises and positioning may require supervision by a provider. An active progressive exercise program designed to achieve or maintain an increase in range of motion and strength should be promoted as the best method of limiting recurrences of low back problems. The exercise program is recommended to be included in the treatment plan and/or referenced in the progress reports. Supervised exercise sessions should be limited to a maximum of four weeks,without re-establishing medical necessity. 4.2.2. Medication 4.2.2.1 Acetaminophen Appropriateness level 4 4.2.2.2 NSAID's Appropriateness level 4 4.2.2.3 Muscle relaxants Appropriateness level 2 4.2.2.4 Oral Corticosteroids Appropriateness level 2 4.2.2.5 Opioid Analgesics Appropriateness level 3 Opioids have significant adverse effects such as decreased reaction time, clouded judgment, drowsiness, habituation and potential for physical dependence. 4.2.2.6 Antidepressants Appropriateness level 3 4.2.3 Physical Treatment Appropriateness level 3 Treatment following the initial trial of four weeks generally should not exceed two times per week. The continuation of treatments is based on reported improvement in subjective complaints, objective factors/clinical findings, and functional capacity. Management may also include active care, education and therapeutic/rehabilitative exercise. Exacerbations may warrant a short course (up to two weeks) treatment of up to three times a week. 4.2.3.1 Traction - static/mechanical for up to two weeks in combination with other physical medicine Appropriateness level 2 4.2.4 Work conditioning Appropriateness level 3 Work conditioning programs which include general conditioning exercises and graduated performance of simulated job tasks may be useful in preparing the injured worker to return to a specific job or in determining work restrictions. The duration of the program should be guided by the documentation of objective functional improvement. The duration of the program may be up to a maximum of four weeks without re-establishing medical necessity. 4.2.5 Transcutaneous Electrical Nerve Stimulation (TENS) Appropriateness level 2 TENS may be useful for management of low back problems. If no functional and symptomatic benefit has been demonstrated after two weeks, this treatment should be discontinued. 4.2.6 Epidural steroid injections Appropriateness level 2 Clinical indications: For a patient with a subacute radicular low back problem who is unable to progress in an active treatment program because of severe leg symptoms and/or neuromotor deficit, an epidural steroid injection may be helpful for symptomatic relief. If successful, a progressive active treatment program should be continued with the goal of avoiding prolonged disability and possible surgical intervention. In general, more than three injections are not recommended. Epidural steroid injections are inappropriate for non-radicular back problems. They should not be used as the sole form of treatment for radicular pain. 4.2.7 Biofeedback Appropriateness level 3 Used occasionally to train the patient to control the symptoms by self regulation of somatic activity developed through instrumentation-enhanced proprioception. Particularly indicated if it reduces the medication usage and/or increases function. If there is no functional and symptomatic benefit after a three week trial, treatment should be discontinued. 4.2.8 Surgical treatment methods Clinical indications: Surgical treatment may be appropriate for injured workers with radicular or other neurological conditions in the following circumstances: 1) Their clinical exam demonstrates persistent symptoms and exam findings that prevent resumption of normal activities, and are unresponsive to an appropriate course of active non-surgical treatment; and 2) Diagnostic test findings objectively verify a surgically remediable condition that correlates with the clinical exam; and 3) There is no significant physical and/or psychological co-morbidity that is likely to lead to a poor surgical outcome for the injured worker. Surgical treatment for mechanical low back problems is rarely indicated. 4.2.8.1 Standard laminectomy with discectomy Appropriateness level 3 Standard laminectomy with discectomy is recommended using the clinical indications listed above. Includes decompression procedures such as standard laminectomy and/or microdiscectomy or variants thereof. 4.2.8.2 Spinal fusion Appropriateness level 2 Spinal fusion for low back problems such as herniated or painful discs is not recommended unless a specific anatomic site of lumbar instability has been identified. Potential sources of instability include degenerative spondylolisthesis, unstable fracture, and surgically induced instability. 4.2.9 Injection therapies 4.2.9.1 Trigger point injections Appropriateness level 2 Trigger point and myofascial injections are not for use as the exclusive treatment modality. When used, they should be limited to three trials of injection therapy. 4.2.9.2 Sacroiliac joint injections Appropriateness level 2 Sacroiliac joint injections should not be used as a sole treatment method. These should be limited to a maximum of three (3). 4.2.10 Acupuncture Appropriateness level 2 Acupuncture treatment is a physical treatment which may be useful following initial treatment to manage pain and to relieve the effects of injury and disease. After a maximum of 12 treatments, the patient is to be re-evaluated for subjective and objective evidence of improvement. If significant subjective and objective improvement is not demonstrated, treatment is to be discontinued. 4.3 Inappropriate Secondary Treatments The following treatments have been determined as inappropriate for secondary treatment: (All are Appropriateness level 1.) 4.3.1 Ligamentous injections (sclerotherapy/prolotherapy) 4.3.2 Laser discectomy 4.3.3 Bed rest 4.3.4 Chemonucleolysis 4.3.5 Percutaneous discectomy 5.0 Prophylactic Treatment 5.1 Purpose Injured workers whose low back problems have improved may benefit from the following measures to help maximize functioning for individuals with persistent mild low back symptoms and to prevent or reduce the impact of recurrent episodes. Appropriate back care strategies should be incorporated into all phases of the assessment and treatment process. 5.2 Appropriate Back Care Appropriateness level 4 5.2.1 Exercise 5.2.2 Back Education and Training 5.2.3 Workplace Modifications 5.2.4 Personal Risk Factor Reduction 6.0 Primary References Submitted and Reviewed in Developing the Treatment Guideline for Low Back Problems The complete list of 216 references considered and reviewed in developing this guideline are available upon request from the Executive Medical Director, Industrial Medical Council, P.O.

Treatment Guideline for Industrial Neck Injuries. The method of treating industrial injury to the neck shall be as set forth below in the "Treatment Guideline for Industrial Neck Injuries" as adopted by the Industrial Medical Council on May 15, 1997. TREATMENT GUIDELINE FOR INDUSTRIAL NECK INJURY Introduction Neck injuries are common among workers. In the majority of injured workers with neck injuries recovery occurs within the first month of symptoms. Those who are not better at one month may need further diagnostic evaluation and consideration of other treatment options. The overall goal of the management of neck injuries in workers is to identify and correct both environmental and personal factors that may be causing or aggravating the injury, while providing appropriate management of disability so that it leads to a return to productive work. Scope of the Guideline This guideline deals with the assessment and treatment of common industrial neck injuries in working age adults. This guideline addresses injuries affecting the neuromusculoskeletal structures of the neck and associated region. Initial assessment to rule out serious neck injuries is discussed, but definite diagnosis and treatment of serious disorders is beyond the scope of this guideline. This guideline does not deal with issues of legal causation or work-relatedness. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted parameters for the assessment and treatment of neck injuries. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed with these types of industrial conditions. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers, for example those with red flag conditions, will not fit the clinical conditions contemplated by a guideline. Symptom duration is classified as acute (< one month), subacute (one to three months), and chronic (> three months). If an injured worker experiences more than one recurrence of neck pain in a year, except in cases of a new injury, it should not be classified and treated as an acute neck problem. In this case, it is considered a recurrent or flare-up neck problem, and secondary assessment and treatment methods should be utilized along with an emphasis on active therapy and prevention strategies. This guideline does not address the evaluation and management of chronic neck problems including chronic pain syndrome. For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with usual practices. A provider may vary from these guidelines if, in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in this guideline and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document, no later than 6 months from the date of injury whether further treatment is warranted and whether the injured worker has significant subjective and objective findings of the condition not having plateaued. 1.0 Initial Assessment of Neck Injuries 1.1 Purpose The purpose of the initial assessment is to establish a working diagnosis and assign the injured worker into one of five initial clinical categories of neck problems: 1) Conditions involving the bony spinovertebral axis such as cancer, infection or fracture; 2) Intraspinal pathology involving neurological conditions such as radiculopathy or myelopathy; 3) Arthritic or inflammatory conditions; 4) Mechanical conditions; or 5) Referred neck pain due to viscerogenic and/or other causes. In addition, the initial assessment looks for (and documents for the chart) other factors which might have an impact upon a injured worker's symptoms and/or response to treatment (e.g., work, personal, psychosocial, and economic factors). 1.2 Appropriate Initial Assessment Methods 1.2.1 History and physical The history and physical examination are the basis upon which any assessment and treatment decisions are to be made. Decisions about diagnostic imaging, laboratory testing, and referral to a specialist should be guided by the clinical features of the history and examination. Only a minority of injured workers will require further diagnostic testing after the initial history and physical examination. In the history, document the characteristics of pain (type, location, duration, severity, radiation), associated symptoms, precipitating factors, positions and activities that aggravate or relieve the symptoms as well as its impact on function at home and work. Information concerning previous neck injuries, diagnostic and treatment procedures, and response to previous therapies (including home treatments and use of appliances) should be obtained. Document any history of prior or repetitive trauma to the neck. The use of a pain drawing and/or pain scale may assist in the evaluation of the location, characteristics, and severity of pain, and be utilized in the assessment of treatment response. The relationship of the symptoms to performance of specific activities should be sought (e.g. computer work, typing, overhead work, hobbies, recreational activities, etc.). In addition, ask key questions pertinent to serious spinal pathology or referred pain (see below). Specifically, ask about neurologic symptoms such as radiculopathy involving an upper extremity or myelopathy involving any extremity or bowel or bladder changes. The initial history should also document relevant past medical and surgical history, occupational history which should include a description of current job duties and the relationship of symptoms to performance of job tasks, and possibly social history which may include tobacco, alcohol and drug use, hobbies, recreational activities, and any pertinent psychosocial issues such as financial, family, or workplace difficulties. A thorough physical examination that is based upon the complete history and presentation of the injured worker is expected. The evaluation includes, but is not limited to, general appearance, visual inspection and palpation, manual testing of range of motion (after fracture and instability have been excluded), vascular and neurologic examination. A focused neurologic examination that includes reflexes with reinforcement, strength and sensation testing in the upper extremities should be performed. Although most injured workers have localized, non-radiating pain with tenderness on palpation and/or limited range of motion, these findings are non-specific for most neck problems. Limited spinal motion may be useful for planning and monitoring response to treatment and developing appropriate work restrictions. Examining physicians are frequently presented with the task of identifying the etiology of the pain generator in the upper extremity. Upper extremity pain may be caused by neurogenic problems, musculoskeletal problems, or referred pain related to visceral problems. For example, pain along the radial aspect of the forearm and hand poses a dilemma as to whether the etiology is focal, such as a de Quervain's tenosynovitis; local, such as a radial nerve entrapment syndrome; or a radiculopathy with referred pain down the C6 nerve root distribution. 1.2.1.1 Consider conditions involving the bony spinal vertebral axis Certain key findings from the medical history and physical examination may raise suspicion of a possible serious underlying condition of the spine which requires immediate diagnosis and prompt treatment, including possible referral for surgical evaluation. The following serious underlying conditions of the spine are suggested by the "Red Flags" listed below: For cancer especially in those people who are 50 years old or older: history of prior cancer, unexplained weight loss, neck pain not improved with rest, or unexplained fever. For infection: fever, immunosuppression, intravenous drug use, history of septicemia, or incapacitating pain. For spinal fracture: instability, history of significant trauma (e.g., motor vehicle accident or fall from height), prolonged use of corticosteroids, severe rheumatologic disease, or alcohol/substance abuse. 1.2.1.2 Consider intraspinal pathology For compromise of the neuraxis related to spinal cord and/or nerve root compromise: history of significant trauma with sphincter control disturbance, or motor, sensory and/or reflex changes involving the extremities. Injured workers with clinical findings that suggest underlying conditions of the spinal vertebral axis or intraspinal pathology may require further studies, such as laboratory tests, x-rays, or specialized tests to evaluate for these conditions. The provider should clearly document the need for any additional tests for other serious pathologies during the initial assessment. Management of serious spinal pathology is beyond the scope of this guideline. Injured workers with such problems should be promptly referred to an appropriate specialist for evaluation and management. 1.2.1.3 Consider arthritic or inflammatory conditions Inflammatory arthridites of the spine which can cause neck symptoms includes ankylosing spondylitis and other spondyloarthropathies. Work-up of these conditions is beyond the scope of this guideline, but should be guided by the clinical findings and suspicion of a systemic illness. 1.2.1.4 Consider mechanical conditions and distinguish from pathology. For the purposes of determining the appropriate management of neck problems and estimating prognosis, it is helpful to classify injured workers into diagnostic categories, as well as consider symptom duration. Most injured workers can be separated into diagnostic categories based on the location and characteristics of their symptoms and findings. 1.2.1.4.1 The symptoms of mechanical (or non-specific) neck problems are predominantly neck pain, with possible referral of pain to the shoulder or upper arm in a non-dermatomal pattern. 1.2.1.5 Consider radicular neck problems resulting from intraspinal pathology involving one or more nerve roots. Presenting symptoms are related to specific nerve root(s) and type of pathology and include pain, alteration in sensation, loss of strength, or altered reflexes in various combinations. 1.2.1.6 Consider cord compression syndromes as a manifestation of spinal pathology such as trauma, degenerative changes, tumors or infections. They are usually complex and beyond the scope of this guideline. However, the provider should be aware of their existence and consider prompt referral to a qualified specialist. 1.2.1.7 Consider referred pain from visceral diseases or other musculoskeletal disorders unrelated to the cervical spine. These conditions can usually be distinguished by a careful history and physical examination. There should be awareness of anginal equivalents. Examination of the shoulder and upper extremity may reveal findings consistent with a localized joint or muscle problem. 1.2.1.8 Consider other psychosocial factors Psychological work factors that are known to increase the reporting of a neck injury and lead to prolonged symptoms and disability include job dissatisfaction. If psychological distress is suspected from the history, pain drawing, and/or the physical examination such as the presence of several "nonorganic" physical signs, the injured worker may be at risk for a delayed recovery or poor response to any surgical procedure. The medical and social history may help the provider evaluate for other risks of delayed recovery and may help plan therapy accordingly. A history of previous neck injuries or surgery, failed previous treatments, prolonged or continuous litigation or disability claims, family or financial problems, or secondary gain may affect treatment response and prolong disability. Chronic pain, depression, and alcohol or substance abuse may prolong disability and influence the choices for therapy. Recreational and other non-work activities which might contribute to neck problems must also be considered in the evaluation and management of neck problems. 1.2.2 Laboratory studies Laboratory tests should not be ordered routinely in the initial assessment unless an underlying illness is suspected. (Mail Survey=4) (Consensus Panel=4) [4] If the injured worker's history, age, or examination suggests cancer, infection, inflammatory arthritis, metabolic or endocrine disorders, or visceral disease, then appropriate laboratory tests may be indicated. The physician must provide a clear rationale of the indications for the test ordered. 1.2.3 Diagnostic imaging Plain x-rays of the cervical spine are recommended for ruling out fractures in injured workers with acute neck problems when any of the following 'red flags' are present: recent significant trauma (any age), recent mild trauma (injured worker over age 50), suspected instability, history of prolonged steroid use, osteoporosis, or any other 'red flag' consideration. (Sec 1.2.1) (M=4) (C=4) [4] Plain x-rays may be required prior to manipulation, mobilization or traction of the cervical spine. (M=4) (C=4) [4] Additional views are not routinely needed but may be indicated on the basis of findings on AP/lateral films. Significant soft tissue injuries may be suspected by the presence of asymmetric spinous process spreading on lateral flexion-extension views. In the presence of 'red flags', as defined in 1.2.1.1, the use of other imaging studies such as bone scan, CT, or MRI may be clinically indicated even if plain x-rays are negative. 1.2.4. Needle electromyography/nerve conduction studies (EMG/NCS) may be appropriate as baseline evaluation in injured workers with a past history of radiculopathy or spine surgery. (C=4) [4] 1.3 Inappropriate Initial Assessment Methods All of the following assessment methods have been determined inappropriate during the initial phase of assessment. Routine use of: 1.3.1 Laboratory studies (M=1) (C=1) [1] 1.3.2 Plain x-rays for evaluation of injured workers with acute neck injuries except as indicated in 1.2.3 (M=1) (C=1)[1] 1.3.3 CT, MRI, myelography, CT-myelography, and bone scan. (M=1) (C=1) [1] 1.3.4 Discography (M=1) (C=1) [1] 1.3.5 Surface electromyography (EMG) (M=1) (C=1) [1] 1.3.6 Computerized strength and range of motion testing (M=1) (C =1) [1] 2.0 Initial Treatment of Neck Injuries 2.1 Purpose The purpose of the initial treatment of neck injuries is to relieve pain and suffering and to restore functional capacity. The goal is to allow the injured worker to resume necessary activities including return to modified or regular work. Injured workers with radicular neck problems and neurologic deficits may require more intensive management and closer monitoring for further neurologic deterioration that may require additional diagnostic testing with possible surgical treatment. Treatment may include: 1) education about neck problems; 2) activity and environmental modifications; 3) exercise; 4) medication; and/or 5) physical treatments as delineated later in this section. This guideline does not address treatment for certain types of conditions such as serious underlying spinal pathology or inflammatory arthritis of the cervical spine. 2.2 Appropriate Initial Treatment Methods in the first month. 2.2.1 Education 2.2.1.1 General information Accurate information concerning soft tissue injury and the usual, expected healing should be provided. (M=4) (C=4) [4] Patients should be given realistic information regarding recovery, and should be taught principles related to posture (e.g., avoid slumping) and daily activities including work and sports. Safe and effective methods of symptom control need to be presented. Patients should be told that, unless there is pending surgical care or question of a fracture, tumor, or infection, special investigations are not warranted. 2.2.2 Activity and environmental modifications 2.2.2.1 Work restrictions Modifications of activities including work specific restrictions which are based on the injured worker's work requirements and clinical findings are desirable if functional limitations do not allow continuation of regular work duties. (M=4) (C=4) [4] Complete work cessation should be avoided, if possible, through the use of modified duty. Written work restrictions should be as specific as possible, and it may be necessary to contact the employer to discuss alternative work within the prescribed restrictions. Injured workers with work restrictions should be re-evaluated within two weeks for determination of work status, response to treatment, and for making appropriate decisions concerning progression to full activities. 2.2.2.2 Environmental/job modification Environmental modifications including engineering (e.g., work station adjustment) and administrative controls (e.g., job rotation) to limit or eliminate work activities that might lead to or aggravate neck problems should be considered early on for symptomatic workers who have work-related risk factors for neck problems. (M=4) (C=4) [4] 2.2.3 Exercise 2.2.3.1 General exercise recommendations Exercise programs under the supervision of a qualified physician or physical therapist may be used for up to 6 visits. Rehabilitative exercise may be indicated to strengthen the neck muscles, for stabilization, to improve range of motion, to normalize posture, and to promote safe body biomechanics. (C=3) [3] There is evidence that one-on-one training in home exercises for cervical motion and extension postures will reduce the duration of pain, compared to rest and the use of a collar. Home programs need to be monitored and reinforced weekly for compliance and progress. 2.2.4 Medications 2.2.4.1 Acetaminophen Acetaminophen has commonly been regarded as having an analgesic effect, but little or no known antiinflammatory effect. (M=4) (C=4) [4] The therapeutic objective for its use in acute neck problems is pain relief. Acetaminophen is reasonably safe and is acceptable for treating injured workers with acute neck problems. 2.2.4.2 Non-steroidal antiinflammatory drugs (NSAID's) NSAID's and aspirin are acceptable for treating injured workers with acute neck problems but have a number of potential side effects. (M=4) (C=4) [4] 2.2.4.3 Muscle relaxants Muscle relaxants are an option in the treatment of injured workers with acute neck problems. (M=4) (C=4) [3] 2.2.4.4 Opioid Analgesics Opioids may be necessary if the pain is refractory to treatment with non-opioid analgesics. (M=3) (C=4) [3] Oral opioid analgesics commonly given to injured workers with cervical problems include morphine derivatives (opioids) and synthetic opioids. Their therapeutic objective in treating neck problems is temporary pain relief. The decision to use opioids should be guided by consideration of their potential complications relative to other treatment options. 2.2.4.5 Other Medications Other medications not mentioned above may also be beneficial with appropriate justification, including, but not limited to: (a) Antidepressants, (C=4) [3] (b) Other non narcotic analgesics (C=4) [3] (c) A short course of oral corticosteroids (C=4) [2] 2.2.5 Physical treatments 2.2.5.1 Manual medicine/manipulative techniques, as performed by a physician defined by the California Labor Code and the scope of practice for each group, may be helpful in injured workers with acute problems. (M=4) (C=4) [4] Neurologic deficits should be clinically investigated and instability resulting from fracture subluxation should be ruled out before manipulation is undertaken. Functional improvement should be demonstrable as well as symptomatic benefit. If this has not occurred after one month, the injured workers should be reevaluated. 2.2.5.2 Manual medicine/mobilization, as performed by a physician or another appropriately licensed health care provider as defined by their scope of practice, may be helpful in injured workers who have acute problems without radiculopathy when used within the first month of the symptoms. (M=4) (C=3) [3] Progressive neurologic deficits should be investigated and instability should be ruled out before aggressive mobilization is undertaken. Functional improvement should be demonstrable as well as symptomatic benefit. If this has not occurred after one month, the injured workers should be reevaluated. 2.2.5.3 Other physical modalities/treatments Manual medicine/therapy can be supplemented by passive modalities including but not limited to iontophoresis, phonophoresis, electrical stimulation, ultrasound, diathermy, and other physical agents during the first four weeks of treatment. (M=4) (C=3) [3] Passive modalities should not be used as the sole form of treatment. They may be combined with an active program which emphasizes progressive exercises. Use of thermal modalities in conjunction with physical treatment may be useful. 2.2.5.4 Frequency of treatment The total number of visits for physical treatments may be up to 12 within the first month. (M=4) (C=4) [4] 2.2.5.5 Transcutaneous Electrical Nerve Stimulation (TENS) Use is limited to 4 weeks in conjunction with other conservative measures. If no functional and symptomatic benefit has been demonstrated after two weeks, this treatment should be discontinued. (C=3) [3] 2.2.5.6 Traction Traction (either manual or mechanical) may be of benefit in the treatment of acute neck problems. (M=4) (C=4) [3] 2.2.5.7 Acupuncture Acupuncture has been reported as useful for acute pain and may be of benefit to facilitate exercises. The frequency of treatment may be up to three times per week for four weeks as long as the injured worker has documented improvement. (M=4) (C=4) [3] 2.2.5.8 Cervical Collars Collars that adequately stabilize the neck may be of benefit for up to a week for acute neck problems. Continual dependence on a cervical collar is not advisable. (M=4) (C=4) [3] 2.3 Case Management Management during the first 4 weeks of treatment will be determined by the clinician's evaluation of the injured worker's response to therapy. Generally, re-evaluation of the problem, determination of treatment effectiveness and work status should be performed every 1-2 weeks until return to modified or full work is achieved. At each visit, the initial diagnosis should be confirmed or modified and the treatment plan adjusted if necessary. If symptoms continue to increase despite adequate conservative therapy, or if there is significant disability due to pain, referral to a provider trained and experienced in the evaluation and treatment of occupational disorders is warranted in the initial treatment phase. Once the acute pain is controlled, the treatment should focus on progressive rehabilitative exercises to increase strength and endurance and activity modification. This approach minimizes the chance of recurrence once normal occupational duties are resumed. 2.4. Inappropriate Initial Treatments The following treatment methods are inappropriate as routine treatment in the initial 4 week symptom phase. 2.4.1 Bed rest (M=1) (C=1) [1] 2.4.2 Surgical treatments (M=1) (C=1) [1] Except for acute neurologic deterioration or structural disruption, surgery is unwarranted. 2.4.3 Exclusive use of passive physical modalities (M=1)(C=1)[1] 2.4.4 Biofeedback (M=1) (C=1) [1] 3.0 Secondary Assessment of Neck Injuries (from 1 - 3 months) 3.1 Purpose The purpose of reassessment is to determine the reason for delayed recovery in injured workers who remain symptomatic and have not functionally improved and returned to regular work after one month of conservative treatment. The first step of reassessment is a complete interval history and physical examination with assignment of the injured worker into one of the five clinical categories: 1) Conditions involving the bony spinovertebral axis such as cancer, infection or fracture; 2) Intraspinal pathology involving neurological conditions such as radiculopathy or myelopathy; 3) Arthritic or inflammatory conditions; 4) Mechanical conditions; or 5) Referred neck pain due to viscerogenic and/or other causes. Depending on the findings, diagnostic evaluation at this point may include spinal imaging tests, bone scan, electrophysiologic tests, lab tests, functional capacity tests, and/or ergonomic evaluation. The clinical indications for each of these diagnostic methods is given below. Physician assessment should be at least twice monthly. Results of all studies should be reviewed and reported within a week. 3.2 Appropriate Secondary Assessment Methods 3.2.1 Plain film x-rays (M=4) (C=4) [4] Clinical indications: Persistent cervical symptoms. 3.2.2 CT, MRI Clinical indications: Findings that suggest compromise of the neuraxis (radiculopathy from a herniated disc and/or spinal stenosis), or a neurologic deficit. These studies are most suitable when surgery is being considered and/or the injured worker has failed an appropriate course of treatment. (M=4) (C=4) [4] Findings are suggestive for tumor or infection, fracture or dislocation. (M=4) (C=4) [4] 3.2.3 Myelography, and CT myelography Clinical indications: Same indications as for CT/MRI, but should only be ordered in conjunction with a specialist referral. (M=4) (C=4) [4] 3.2.4 Bone scan Clinical indications: Findings on history, examination, laboratory or other imaging studies are suggestive for, but not limited to, tumor, infection, fracture, arthritis, and reflex sympathetic dystrophy. (M=4)(C=4)[4] 3.2.5 Laboratory testing Clinical indications: As deemed appropriate by the reassessment findings. (M=4) (C=4) [4] 3.2.6 Needle electromyography / nerve conduction study (EMG/NCS) Clinical indications: EMG/NCS may be helpful for evaluating suspected nerve root dysfunction, or neuropathy. (M=4) (C=4) [4] 3.2.7 Ergonomic evaluation Clinical indications: A worksite evaluation with the affected injured worker may be performed if clinically indicated. (M=4) (C=3) [3] The evaluation should be done by a professional trained in these types of evaluation. History, job description, and workplace inspection can be useful to identify physical work factors that may be contributing to the development or exacerbation of neck problems,which can prevent return to usual work. 3.2.8 Psychological Assessment Clinical indications: Focused psychological assessment may be indicated if factors (e.g., stress, job dissatisfaction, depression, substance abuse, symptom magnification) may be contributing to delayed recovery, noncompliance or lack of response to appropriate treatment in subacute and chronic neck problems. (M=4) (C=4) [4] In an injured worker manifesting signs of risk for delayed recovery, psychological assessment may be helpful for determining if significant psychological or personality factors are contributing to the injured worker's disability. The presence of several "nonorganic" physical signs may also identify injured workers who need further psychological testing and evaluation. These injured workers may need specific behavioral or psychological treatments early on. Psychological and personality evaluations may be utilized preoperatively in an injured worker who is being considered for surgical treatment to assist in selection and planning if a behavioral intervention is necessary. 3.2.9 Somatosensory evoked potentials (SEP) should only be performed after EMG and other diagnostic modalities have proven to be of no help and specific justification must be given. (M=4) (C=3) [3] 3.3 Inappropriate Secondary Assessment Methods The following methods have been determined inappropriate for secondary assessment. 3.3.1 Discography (M=1) (C=1) [1] 3.3.2 Surface EMG (M=1) (C=1) [1] 3.3.3 Diagnostic blocks and injections including facet joint injections are inappropriate at this phase of the treatment. (M=1) (C=1) [1] 3.3.4 Computerized strength and range of motion testing Computerized testing is only useful if it leads to a specific exercise program which allows measurable progress. Its routine use is not recommended. (M=1) (C=1) [1] 4.0 Secondary Treatment of Neck Injuries 4.1 Purpose The purpose of secondary treatment is to provide symptomatic relief for the injured worker with a cervical problem while continuing to intensify efforts in active treatments, such as exercise. The goal of secondary treatment is to prevent progressive deconditioning and permanent disability, while promoting return to full work for those who are either off work or on modified duty. Treatment is based on the findings of the diagnostic re-evaluation at four to six weeks. 4.2 Appropriate Secondary Treatment Methods 4.2.1 Physical treatments Treatment following the initial trial of four weeks generally should not exceed two times a week. (M=4) (C=3) [3] The continuation of treatments is based on reported improvement in subjective complaints, decreased objective factors/clinical findings, return to work, or decreased work restrictions. Active care, education and rehabilitative exercise may be indicated for strengthening of the neuromusculoskeletal structures of the neck and associated regions and for pain control. (M=4) (C=4) [4] 4.2.2 Work conditioning Work conditioning programs which include general conditioning exercises and graduated performance of simulated job tasks may be useful in preparing the injured worker to return to a specific job or in determining work restrictions. (M=4) (C=4) [4] 4.2.3 Epidural steroid injections Clinical indications: For a patient with a radicular neck problem, a trial of epidural steroid injections may be helpful for short-term pain relief and avoiding surgery. (M=4) (C=4) [3] 4.2.4 Surgical treatment methods Clinical indications: Surgical treatment may be appropriate for injured workers with radicular neck problems in the following circumstances: 1) the clinical evaluation demonstrates persistent symptoms and findings that prevent resumption of normal activities, and they are unresponsive to an appropriate six weeks of active non-surgical treatment; and 2) the diagnostic test findings objectively verify a surgically remediable condition that corresponds with the clinical exam; and 3) surgery is not contraindicated by significant physical or psychological comorbidity that might suggest a poor surgical outcome for the injured worker. (M=4) (C=4) [4] 4.2.5 Injection therapies 4.2.5.1 Trigger point injections Standard trigger point injections with saline or local anesthetic are only for occasional use, not standing alone as a sole treatment but as part of a multi-disciplinary approach. (M=4) (C=4) [3] 4.2.6 Acupuncture Acupuncture treatment is a physical treatment which may be useful following initial treatment to manage pain. Treatment may be up to 12 visits in 8 weeks as long as the injured worker is showing documented, incremental improvement. (M=4) (C=4) [3] 4.2.7 TENS Unit Use is limited to four weeks in conjunction with other conservative measures. (C=4) [3] 4.2.8 Appropriate medication as listed under 2.2.4 (M=4)(C=4) [4] 4.2.9 Biofeedback [3] 4.3 Inappropriate Secondary Treatments The following treatments have been determined as inappropriate for secondary treatment: 4.3.1 Ligamentous injections (sclerotherapy/prolotherapy) (M=1) (C=1) [1] 4.3.2 Bed rest (M=1) (C=1) [1] 4.4 Case management If the injured worker has not resumed near normal work duties after 8 weeks in the secondary treatment phase, including adherence to a graded exercise program, a referral to a physician or surgeon trained and experienced in the evaluation and treatment of occupational disorders is recommended. Consultation should include a complete evaluation and recommendations for treatment and return to appropriate work. If psychosocial issues are judged to contribute to delayed recovery or heightened disability, it may be appropriate to have a psychiatric evaluation. If the condition becomes chronic or disabling despite full conservative treatment including appropriate medical, rehabilitative, and ergonomic interventions (and surgery if indicated), the injured worker should be evaluated for permanent disability. 5.0 Tertiary Management of Neck Injuries Late rehabilitation after three months of disabling symptoms may require a multi-disciplinary approach focused on returning the injured worker to work. At this time, this guideline does not address the evaluation and management of chronic neck problems including chronic pain syndrome. 6.0 Primary References 1.

The method of treating contact dermatitis shall be as set forth below in the "Treatment Guideline for Contact Dermatitis" as adopted by the Industrial Medical Council on July 20, 1995. TREATMENT GUIDELINE FOR CONTACT DERMATITIS Contact dermatitis Contact dermatitis is a common problem among workers and constitutes approximately 5.7 million physician visits per year. All age groups are affected, and there is a slight female predominance as reflected in patients seen for diagnostic patch testing. The complex nature of the chemical environment (natural and synthetic) in which we live brings the skin into contact with many potential exposures which may or may not pose a hazard, depending on individual susceptibility. There are more than 100,000 chemicals in the environment today. Almost any substance can be an irritant, depending on the exposure circumstances. Further, over 2,800 substances have been alleged to be contact allergens. The potential for these substances to cause contact dermatitis varies greatly, and thus the severity of the dermatitis ranges from a mild, short-lived condition to a severe, persistent, job-threatening and sometimes life-threatening disease. Contact dermatitis is an altered state of skin reactivity induced by exposure to an external agent. Substances which produce this condition after single or multiple exposures may be irritant or allergic in nature and will often present as an inflammatory process. Direct tissue damage results from contact with irritants. Following contact with strong irritants the reaction is immediate with blistering and pain, resembling a burn. From contact with weak irritants, the reaction develops more slowly, over several days or weeks, with redness, pain and/or itching, and scaling. Tissue damage by allergic substances, however, is mediated through immunologic mechanisms; the reaction consists of redness, marked itching, slight thickening of the skin and/or small vesicles at the site(s) of contact. The generic term for both of these conditions is contact dermatitis. Tissue damage by allergic substances is mediated through immunologic mechanisms. The most common clinical expression of this induced inflammation is dermatitis (eczema). CAUTION: Exogenous dermatoses may morphologically and histologically mimic endogenous dermatoses, and vice versa, and may co-exist. Before considering a job change, or if chronicity is involved (more than 12 weeks), appropriate consultation is indicated. Scope of the guideline : This guideline deals with the assessment and treatment of contact dermatitis in working-age adults. Another contact elicited phenomenon, the contact urticaria syndrome, which in its immunologic form, has produced fatalities, is not discussed here. A physician may vary from these rules if in the judgment of the physician, variance is warranted to meet the health care needs of the patient and that variance remains within the standards of practice generally accepted by the health care community, and the physician documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the physician is necessary to monitor and explain the use of variances. I. Initial Assessment A. Purpose Accurate diagnosis is the key to proper management of contact dermatitis. If the agent(s) causing the dermatitis can be found and successfully avoided, recovery can be anticipated; but if contact continues, the dermatitis may become chronic, disabling, and a serious threat to continued work and the activities of daily living. After prolonged and repeated episodes of dermatitis, a small number of individuals may not fully recover, even with adequate medical care and following avoidance of its causes. B. Appropriate assessment methods 1. History may include: a. General medical status b. Onset 1) Location 2) Symptoms -- itching, burning, sting 3) Description -- redness, blisters, scales, urtication (welts), dryness, rash 4) Home remedies used, including over-the-counter preparations. c. Progression 1) Relation between exposure and time interval of dermatitis 2) Relation to home and recreation 3) Relation to specific work activity 4) Relation to activity -- sweating, friction, pressure, heat, cold, etc. 5) Relation to sun/air exposure, season, and time of day d. Remissions 1) Relation to non-work related weekends and/or vacations 2) Response to treatment and rapidity of recurrence after discontinuing medication 3) Relation to stress and/or anxiety 4) Relation to water exposure e. Occupational history 1) Exact nature of work 2) Duration of present activity 3) Others similarly affected 4) Changes in procedure or chemical exposure 5) Protective measures -- type and effectiveness 6) Related symptomatology -- burning eyes, sneezing, wheezing, asthma, and anaphylaxis 7) Cleansing agents -- type and frequency of use 8) Hand washing frequency and agents used; protective creams -- type and use 9) Second job 10) Review of Material Safety Data Sheets in relation to patient's job 11) Moisturizers and over the counter topicals 12) Other factors f. Other exposure 1) Hobbies and non-work activities a) Gardening, house plants, lawn care, and other outdoor activities (e.g., poison ivy, oak, and sumac, chrysanthemums, primula, Peruvian lily) b) Knitting, sewing, macrame c) Painting, ceramics, jewelry d) Cooking, baking e) Wood working, carpentry, gluing f) Auto, motorcycle, truck repair g) Photography and photographic developing h) Sports i) Other 2) Animals and substances on their skin or fur a) Dogs and cats b) Birds and caged animals c) Farm animals, horses d) Other 3) Cosmetics, fragrances, and personal care products a) Soaps and detergents b) Shampoos and other scalp/hair products c) Creams and lotions d) Perfumes, colognes, deodorants e) Nail polishes, artificial nails, and nail/cuticle products f) Consort or other interpersonal contact/products g) Other 4) Household activities and products a) Dishwashing products b) Laundry detergents c) Furniture waxes, polishes, and dusting agents d) Bathroom cleaning agents e) Floor care products f) Use of gloves (type and frequency) g) Other g. Family history 1) Atopic background -- nature, prevalence and severity including relation to eczema 2) Ichthyosis, psoriasis, and hand eczema or other significant skin disorder 3) Family members with contact dermatitis a) Relationship b) Age of onset c) Type and severity of problems d) Results of therapy and/or testing procedures e) Other h. Past medical history 1) History of contact dermatitis -- nature, severity, and causative agent(s), if known 2) Previous treatment a) At onset b) Self treatment -- over the counter treatments -- relation to dermatitis c) By other physicians 3) Medications -- topical and systemic -- past and present -- relation to dermatitis as well as medication allergy 4) Other 2. Physical examination may include: a. Location 1) Symmetry 2) Involved vs. uninvolved skin a) Demarcation--sharp or unclear b) Evidence of protection by clothing c) Distribution suggestive of photo or air-borne pattern exposure (e.g., exposed or uncovered skin areas) b. Lesion type 1) Acute a) Dermatitis (eczema) b) Vesicular/bullous c) Urticarial d) Excoriations e) Crusts 2) Chronic a) Lichenification b) Pigmentary changes c) Atrophy d) Scarring e) Loss of hair c. Other 3. The patch test The patch test is the standardized diagnostic procedure of choice for allergic contact dermatitis. In general, practitioners who do such patch testing should adhere to the following guidelines when performing patch tests. It should be used only by primary care physicians with previous knowledge, training and skill in the application and interpretation of such testing. In the vast majority of cases, patients who require patch testing should be referred to a dermatologist or allergist who includes patch testing in his/her practice. a. Standardized test kits containing a number of allergens are available. In testing with substances brought from work, appropriate dilutions must be used to avoid irritant reactions which can be very severe. In general, testing with raw substances from the workplace should be done by a dermatologist or allergist experienced in patch testing. b. The most widely used patch test material consists of strips of paper tape onto which are fixed 8 mm diameter aluminum discs. A small amount of allergen is placed within these discs, discs, covering slightly more than one-half the diameter of the disc providing a dose approximately 17 ul. c. Apply the patch to the upper or mid back, which must be free of dermatitis and devoid of hair. If shaving is necessary, it should be done only with an electric razor. d. Leave the patch in place and keep dry for two days (48 hours) before removing unless symptoms of severe reaction occur. e. Read tests: 1) The same day that patches are removed from the skin, allowing 20-30 minutes for erythema to resolve before preliminary interpretation. 2) One additional reading at 72 or 96 hours, and occasionally at one week. Reading solely at 48 hours will miss up to 35% of positive reactions. 3) If two readings are impossible, a single reading three or four days (72-96 hours) after patches are initially applied. f. Grade test reactions according to intensity (International Contact Dermatitis Research Group Scale): [Color plates available] 1) 0 = no reaction. 2) ?(+ or - reaction) = weak erythema only. 3) 1+ = erythema with edema. 4) 2+ = erythema and papules. Tiny vesicles are present over the surface. 5) 3+ = vesicles or bullae. g. Interpret reactions cautiously: 1) 0 = no evidence of contact allergy. 2) ? = doubtful existence of contact allergy. 3) 1+ = possible contact allergy. (1+ is a common intensity of false positive reactions). 4) 2+ and 3+ = probably contact allergy. 5) If several questionable and 1+ reactions are present along with strong 2+ or 3+ reactions, the weaker reactions may mean that the "excited skin syndrome" is present, the weak reaction representing only irritation. 4. Additional tests of occasional value a. Skin biopsy to differentiate from other diseases. b. Open application of a suspected allergenic product to the antecubital fossa twice daily for up to one week (the PUT, Provocative Use Test or ROAT, repeat open application test). This is applicable to leave-on products intended for use on the skin, not wash-off products. c. Prick or scratch test in the evaluation of contact urticaria. Emergency resuscitation equipment should be available. Contact urticaria should first be evaluated with an open test on sites adjacent to active dermatitis. d. Chemical analysis of environmental materials to determine if they contain a substance to which the patient is patch-test positive. The most commonly employed of these is the dimethylglyoxime test for nickel. e. Potassium hydroxide (KOH) preparation, fungal and bacterial cultures and appropriate laboratory examinations as needed. C. Inappropriate initial assessment methods 1. Occlusive patch test with irritant concentrations of material or material where the irritant concentration is unknown. 2. A specific IgE (RAST) test is not helpful in the diagnosis of contact dermatitis (with the exception of contact urticaria when prick or scratch tests may be hazardous). 3. Sublingual allergen application with vital sign monitoring as an indicator of adverse reactions. D. Evolving diagnostic tests In vitro lymphocyte stimulation tests, migration inhibition factor, and other laboratory tests of lymphokine production remain investigational tools which at present are insufficiently standardized to allow clinical application. II. Initial Treatment A. Purpose The purpose of initial treatment is to prevent further exposure to the causative agent(s) and control itching and/or edema. B. Appropriate initial treatment methods 1. Topical treatment Topical treatment alone may be indicated for mild cases of contact dermatitis, limited site of involvement, acute contact dermatitis when the offending agent has been removed, or chronic contact dermatitis with limited symptoms. Topical therapy most commonly used includes but is not limited to: a. Cool compresses with saline, water, milk, aluminum subacetate, or other agents for acute, blistering dermatitis b. Shake lotions, such as calamine c. Topical corticosteroid cream, ointment, lotion, gel, or spray d. Colloidal oatmeal baths e. Antibiotic treatment, if required, should be systemic only (Many antibiotic creams and ointments are sensitizing.) f. Coal tar in low concentration (in chronic eruptions) g. Emollients, lubricants, moisturizers (in chronic eruptions) and for prevention of irritation h. Non-alkaline cleansers instead of soap 2. Systemic treatment Systemic treatment may be indicated for control of itching and/or edema even in cases of limited extent. Systemic treatment may also be indicated for moderate to severe acute and/or chronic contact dermatitis. Systemic therapy most commonly used includes but is not limited to: a. Antihistamine -- sedative types for nighttime sedation; non-sedating types for daytime use. b. Corticosteroids, oral or intramuscular (Intravenous corticosteroids may be useful in severe acute cases) c. Antibiotics, oral or parenteral (when secondary infection may be present) d. Other anti-inflammatory or immunologic agents 3. Other a. Ultraviolet B radiation (used only for chronic, resistant dermatitis, with treatment supervised by a dermatologist) b. Psoralen (topical or oral) and ultraviolet A radiation, supervised only by a dermatologist c. Mechanical protection against allergens and irritants (e.g., gloves, protective clothing, protective barrier creams) d. Removal or avoidance of causal allergens and/or irritants 4. Education Patient education about the nature of the dermatitis, triggering allergen or irritant factors, and suggestions for avoidance or substitution of these factors in the patient's environment may be helpful in management. Discussion should include proper selection and wearing of gloves and other protective clothing, personal cleanliness, use of hand creams, avoidance of home irritants, especially soaps, shampoos, solvents, etc. III. Secondary Assessment (Reassessment at One to Three Months) A. Purpose It is critical to obtain specialized consultation and possibly a complete diagnostic patch testing and possibly immediate type testing before considering a worker as being unfit for work for dermatologic reasons. For a simple case of irritant contact dermatitis, if there is no improvement after 2-3 weeks of treatment, and especially if the condition is becoming worse, referral to a dermatologist should be made. Referral should be made immediately, however, if there is uncertainty regarding the diagnosis. B. Appropriate secondary assessment methods In unclear diagnoses, other lab tests including KOH preparation, microbial cultures, and biopsy should be considered. IV. Secondary Treatment A. Purpose In unusual cases, specialized nonspecific therapies may be helpful. Consultation should be sought before initiating this. B. Appropriate secondary treatment methods This includes localized or systemic PUVA (Psoralen UVA). V. Prevention A. Purpose Minimizing exposure to allergens is essential. B. Appropriate preventive measures 1. Appropriate engineering steps to enclose the chemical and/or physical exposure 2. Appropriate hygiene including: a. Change of clothing b. Protective clothing c. Appropriate gloves 3. Appropriate dermatotoxicologic consultation to identify an alternative process or chemical to substitute for the agent causing a documented allergic contact dermatitis. 4. Appropriate skin care with the least irritating and sensitizing cleansing agents and moisturizers VI. Primary References 1. Adams, R.M., M.D., Occupational Skin Disease, 2nd Ed., W.B.

The method for treating post-traumatic stress disorder shall be as set forth below in the "Treatment Guideline for Post-Traumatic Stress Disorder" as adopted by the Industrial Medical Council on December 17, 1996. TREATMENT GUIDELINE FOR POST-TRAUMATIC STRESS DISORDER I. Introduction: The Industrial Medical Council and supporting advisory committees were established in 1989 as part of workers' compensation reform. The Psychiatric Advisory Committee followed a legislative mandate to revise the disability evaluation protocols for psychiatric injury which were accepted into law by the Office of Administrative Law on December 7, 1993. The legislature also mandated the IMC to develop guidelines for common industrial injuries. Violent encounters and exposure to life threatening events are common occurrences in the workers' compensation system. According to the Bureau of Labor Statistics for the calendar year 1992, 1,004 homicides took place at the work site and 22, 400 attacks occurred in the national workforce. The IMC and the Psychiatric Advisory Committee have thus selected post-traumatic stress disorder (PTSD) as the focus for establishment of treatment guidelines. The California legislature made subsequent changes to the workers' compensation system including a higher threshold of compensability for psychiatric injuries. For injuries that occur after July 17, 1993, an injured worker must prove that the "actual events of employment" were the "predominant cause" (at least 51%) among all of the combined causes of the psychiatric injury. However, if the psychiatric injury results from a violent act, or from direct exposure to a significant violent act, the actual events of employment must have been a "substantial cause" (at least 35%) of the injury (Lab. Code s 3208.3). The Psychiatric Advisory Committee, composed of psychiatrists and psychologists from different geographic locations in California, developed these guidelines following committee deliberations, a review of the clinical literature of PATS, and input from national experts. Scope of this guideline : This guideline does not deal with legal issue of causation or work-relatedness. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed in these types of industrial conditions. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers will not fit the clinical conditions contemplated by a guideline. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with the Official Medical Fee Schedule. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the physician is necessary to monitor and explain the use of variances. The physician may wish to advise the parties of the availability of the Cal/OSHA guidelines for workplace security from the Division of Occupational Safety and Health. II. Background on the Concept of Post-Traumatic Stress Disorder (PTSD): The diagnosis of post-traumatic stress disorder was first established in the Diagnostic & Statistical Manual, 3rd Edition (DSM-III) by the American Psychiatric Association in 1980. The earlier DSM-I (1952) listed a diagnostic category entitled stressors resulted in a state of fearfulness. More recently DSM-IV (1994) has added the category called Acute Stress Disorder for individuals who experience a brief episode of symptoms that resemble those that occur in PTSD following exposure to an extreme stressor. The medical literature details the phenomenon of post-traumatic stress disorder dating back well before this century. DaCosta published a paper in the " American Journal of Medical Science" (1871) regarding "irritable heart" found in Civil War soldiers who complained of chest pain, palpitations and dizziness subsequent to exposure to battle scenes. "Shell shock" is a concept that came forth in the medical literature that relates to the description of front line soldiers' emotional states during World War I. In World War II a number of papers were published concerning the concept of "traumatic neurosis" again addressing the emotional response on the part of soldiers to witnessing and experiencing serious trauma. Over the past two decades, numerous publications have described similar post-traumatic stress reactions among civilians exposed to catastrophic violence, disaster and traumatic injury. This literature has also documented that the witnessing of life threat, injury or traumatic death to another may result in the full spectrum of post-traumatic symptoms. The anxious response in patients diagnosed as having PTSD may well relate to increased catecholamine excretion. Studies of Vietnam veterans have found increased levels of noradrenergic metabolites compared to the normal population. Psychological theories point toward the breakdown of the individual's normal defenses such as the use of denial in coping with anxiety related to one's own mortality. Mardi Horowitz (1986) described several stages that patients experience in treatment for PTSD including the traumatic event, outcry, denial, intrusive symptoms, working through and completion. Research involving psychological and biological factors is consistent with PTSD as a separate and distinct disorder from patients with a clinical depressions. It should be noted that not all those exposed to serious trauma develop symptoms of PTSD. Not all those diagnosed with PTSD go on to become disabled. Symptomatology should not be equated with functional impairment. The lifetime prevalence of PTSD is somewhere between 1.3 to 9% of the general population (Breslau, 1991) and 15% in psychiatric inpatients (Saxe, 1993). The majority of victims of the Buffalo Creek Flood and the Coconut Grove Fire were noted to have post-traumatic symptomatology. Fifteen percent of Vietnam Theater veterans twenty years after the war were diagnosed with PTSD according to the National Vietnam Veterans Readjustment Study (1990). Thus, the diagnosis is by no means uncommon. Studies to date indicate that the severity of exposure to direct life-threat and the witnessing of mutilating injury or death is strongly positively associated with severity of post-traumatic stress reaction. PTSD varies with type, intensity and duration of trauma. III. Diagnosis: Post-traumatic stress disorder and acute stress disorder fall within the anxiety disorders category according to the current Diagnostic and Statistical Manual (DSM-IV). [FN1] Certain criteria must be met for the diagnosis of PTSD to be made. It is essential that the individual experience, witness or be confronted by an event(s) that involve actual or threatened death, serious injury or threat to the physical integrity of oneself or others. The individual must respond by experiencing intense fear, helplessness or horror. There are three symptom categories of PTSD: reexperiencing, avoidance and arousal. The individual goes on to reexperience the event through such things as intrusive recollections and disturbing dreams. Prominent symptoms include avoidance and numbing. Increased arousal is manifest through disturbance of sleep, hypervigilance, exaggerated startle responses and other symptoms. For acute stress disorder the disturbance lasts at least two days and for a maximum of four weeks whereas for PTSD the diagnosis can be made where symptoms are present for more than one month. The disorder causes distress or impairment in social, occupational or other areas of functioning. If the duration of symptoms is less than three months the condition is deemed acute. If three months or longer, then the descriptor of chronic is appropriate. Delayed onset PTSD occurs when symptoms make their appearance six months or longer after the recognizable stressor. Examples of traumatic exposures provided in DSM-IV include but are not limited to exposure to combat, violent personal assault, kidnapping, hostage situations, terrorist attacks, torture, concentration camp incarceration, disaster situations, severe automobile accidents or diagnosis with a life-threatening illness. It should be noted that the stressors can be sudden, circumscribed and singular or they may be cumulative and repetitive. Either an individual can be responding to a single hold-up or a series of bank robberies, for example. Natural as well as man-made and intentional trauma can result in features of PTSD. Guilt amongst survivors of serious trauma situations may be a predominant theme. A pre-existing psychiatric disorder or a history of significant trauma, whether related to the current event or not, has been associated with risk of a more severe reaction to a current traumatic exposure. There is some debate about the extent to which PTSD symptoms overlap with those of depression, substance abuse and other anxiety disorders, which commonly occur with it. There is also some controversy about the type of traumatic events and required levels of intensity that qualify for meeting the diagnostic criteria. The change in the stressor criterion from DSM-III-R to DSM-IV was prompted by the recognition that many extremely traumatic experiences are common enough among the general population not to be deemed "outside the range of usual human experience." The stressor criterion now includes meeting criteria for both objective features, e.g., life-threat or witnessing injury, and subjective features, e.g. horror, terror, intense fear or helplessness. Whereas the inclusion of subjective reactions may appear to some clinicians to broaden the potential range of events that may qualify for the diagnosis, the objective features do not differ from those mentioned in DSM-III-R. Some clinicians may use diagnostic terms such as a typical PTSD or diagnose PTSD when only secondary symptomatic criteria are met without the initial stressor criteria. Some clinicians make reference to a psychologically "toxic work environment" as sufficient for the diagnosis for PTSD. There are also instances in which corroboration cannot be consistent with malingered or factitious presentations. Where all of the criteria are not met for PTSD or acute stress disorder, the differential diagnosis should include other considerations such as an adjustment disorder, other anxiety disorders, mood disorders, personality disorders, and even psychotic decompensation with this listing not being all-inclusive. In order to make a correct psychiatric diagnosis treating and evaluating clinicians need to take a thorough history, review all appropriate medical and administrative records, and consider other sources of corroborating data. In making an assessment of whether a patient meets the criteria for PTSD, inquiry should be made about the objective features of the referent traumatic event. The patient's subjective experience should be ascertained in such detail as to determine the patient's appraisal of the threat(s) and severity of subjective reactions. Just as in the assessment of other psychiatric disability situations, there is an appropriate role for psychometric testing that can add additional data concerning the veracity of the applicant's reporting, the severity of symptomatology experienced and the style of coping for that individual. IV. Treatment Considerations: Most clinicians and researchers agree that early intervention is called for in cases of acute stress disorder and in cases of post-traumatic stress disorder when later identified. Critical incident stress debriefing at times can be brought about at the worksite, allowing employees to discuss their joint experience of a workplace trauma such as a bank robbery. This type of group intervention can provide psychoeducation and reassurance about the range of normal expected reactions to serious traumatic situations. It also gives clinicians the opportunity to suggest ways of coping with secondary stresses, traumatic reminders and losses. It must be kept in mind that a group of employees may have a wide range of exposures to the same incident. For those employees with the most severe levels exposure, critical incident debriefing alone is likely to be insufficient. In the aftermath, individuals with more serious symptoms or those at greater risk need to be identified and provided with further symptomatic assessment and intervention. A. There are different models of psychotherapy for PTSD that are appropriate. Some take a supportive approach that is consoling. Others use a group approach allowing patients to develop a shared experience. Some clinicians use short-term individual treatment such as that developed by Horowitz and Marmar at UC San Francisco, or short-term group psychotherapy. Additional approaches involve a more long-term working through of the trauma. Recovery from PTSD may have a phasic course, in part, due to expected traumatic reminders such as physical rehabilitation, criminal proceedings, return to the worksite where violence or disaster occurred, and anniversary reactions, as well as unexpected reminders. Short-term psychotherapy, therefore, may need augmentation by periodic follow-up brief psychotherapy sessions in preparation for, during and after such occasions. Treatment should be targeted and focused on symptom removal rather than on uncovering pre-existing psychopathology and addressing personality change. Cognitive behavioral therapy employing exposure-related techniques to address painful memories of the original experience can be very effective in reducing the fear that often times accompanies the PTSD syndrome. Cognitive approaches may also be used to restructure the meaning attributed to the experience. These techniques can utilize the therapeutic assignments outside the office. In vivo exposure at the work site following discussion in the therapy setting can also be a powerful adjunct to treatment. More general behavioral interventions can also be useful, for example, the use of relaxation techniques to reduce reactivity to trauma-related cues or reminders, desensitization for phobic symptoms, and sleep induction. B. Psychotropic medication is a common component of treatment. Anti-anxiety medication, especially for acute stress disorder, and tricyclic antidepressants have been shown to assist with sleep induction and can suppress the REM component of sleep in which disturbing dreams can come forth. Imipramine can reduce intrusive symptomatology through action on noradrogernic receptor sites in the brain. Amitriptyline and selective serotonin re-uptake inhibitors (SSRI's) such as fluoxetine can reduce numbing and hyperarousal through serotonergic sites. The SSRI's tend to be well tolerated. There is also a rationale for other types of antidepressants such as the MAO inhibitors, mood stabilizing agents such as lithium and valproic acid, adrenergic blockers such as propanolol and clonidine, antipsychotic agents for agitation and paranoia, as well as other psychotropics depending on the severity of symptoms and their duration. The Advisory Committee recommends treatment be placed into three categories for establishing treatment based upon DSM-IV criteria. Certain general treatment principles apply. Early clinical intervention soon after the identified workplace trauma can reduce morbidity and disability. An increased frequency in sessions beyond weekly on a short term basis can be appropriate, particularly, early in treatment. Treatment may be appropriate and necessary that exceeds the following guidelines when complicating factors influencing the frequency and duration of treatment are present and documented. There are cases where maintenance treatment may be necessary, especially utilizing supportive psychotherapy and psychopharmacologic approaches for individuals who have experienced extreme trauma and/or present with ongoing symptoms that justify such measures. Psychopharmacologic management visits can be separate from the psychotherapeutic sessions and should not reduce the total number of psychotherapy sessions made available to PTSD patients. 1) Acute Stress Disorder. This condition is present when symptoms have a duration of up to one month subsequent to the traumatic event. The treatment should involve a brief psychoeducational approach lasting one to eight psychotherapy sessions. Positive outcome expectations should be fostered. The patient should be assured that his/her responses are a normal reaction and that they usually disappear in a short time. The use of illicit substances or alcohol as a means of coping should be discouraged. Psychotropic medication is generally restricted to the occasional use of anxiolytics, antidepressants, or hypnotics to assist sleep. The major goals of this treatment approach are normalization, positive expectation, catharsis and desensitization. 2) Acute PTSD. The duration of symptoms is from one to three months subsequent to the industrial trauma. Typically for this type of case where the individual responds to a recognizable stressor, short-term psychotherapeutic treatment, which may be accompanied by the use of medication, is provided for approximately 12 to 16 psychotherapy sessions. 3) Chronic or Delayed PTSD. (The committee suggests that this category be considered for cases of complicated or protracted PTSD.) The duration of symptoms is beyond a period of three months following the trauma. Persistent and significant symptomatology may continue in certain individuals who have received short-term treatment. Complicating factors may include the nature of the initial stressor, prior psychiatric treatment or prior history of trauma/abuse. In such instances treatment beyond the short-term intervention model is appropriate and necessary. Treatment may require 35 to 55 psychotherapy sessions in such instances with justification by the treating clinician. (More frequent therapy and the ongoing use of medication may be warranted.) There are cases where additional treatment may be necessary beyond a period of one year. When treatment is to extend beyond a period of one year, justification by the treating clinician is warranted. Reevaluations by non-treating clinicians at periodic intervals to address the efficacy of treatment can be useful. An opinion from a psychiatrist or psychologist is necessary to amend or discontinue treatment. That opinion must be based upon medical evidence in the case being reviewed. Factors influencing the frequency and duration of treatment in complicated PTSD. Risk factors which may complicate treatment and the course of the clinical presentation include: a childhood history of trauma, poor social supports, a history of alcohol and drug abuse, lasting physical injury, and disruption of marital and family functioning. As noted above, a history of prior psychiatric treatment can complicate the treatment for the more recent traumatic event. Furthermore, a co-morbid diagnosis with an additional psychiatric condition such as a major depression or a psychotic disorder can add to the complexity and prolong the course of treatment. Personality disorders can also result in resistance to treatment requiring more skill on the part of the treating clinician and at times more treatment resources. Some of the types of maladaptive traits that are intensified by traumatic exposure include paranoia, dependency and avoidance. While treatment for a pre-existing personality disorder or other pre-existing psychiatric condition may not be caused by the traumatic event, complicating maladaptive traits or symptoms may need to be recognized and treated to the extent necessary to provide maximum PTSD treatment efficacy. The influence of legal and administrative factors is significant for injured workers within the workers' compensation system. Symptom prolongation can come about as the result of an inability to resolve the applicant's claim, thus drawing out the need for supportive psychotherapy or counseling. Symptom exacerbation can also occur as a result of repeated examinations, depositions, and court testimony, at times related to other legal matters such as criminal proceedings. In extreme cases patients may present with concomitant syndromes such as major depression which can require inpatient treatment. While acknowledging complicating factors that can prolong treatment and disability, clinicians should be mindful for the potential for secondary gain. Reducing symptomatology, improving functional ability and returning the injured worker to the work force should be the achievable goal of treatment in most cases. V. Clinical Interventions/Recommendations Beyond Treatment: While not under the rubric of clinical treatment, other types of interventions can be extremely helpful in assisting the employee to return to a more functional status and ultimately to some type of employment whether with the employer of record or at an alternative worksite. In some cases of PTSD, treating or clinicians will issue recommendations for measures in addition to treatment. These include recommendations for accommodations at the worksite. For example, a bank teller may have to be taken off the teller line following a bank robbery for a period of time. Certain individuals can be accommodated by being placed in positions where they do not handle money subsequent to a robbery event. Clinicians may recommend improving security measures at the worksite. The treating doctor may indicate that it is appropriate for his/her patient to take a self-defense class as a means of empowering the individual in addition to teaching the person how to protect himself or herself in a potential similar situation in the future. Also during the treatment phase a treating doctor may collaborate with the vocational counselor about the worker taking incremental steps toward venturing out into the public, taking on the challenge of retraining or returning to the work site. Where appropriate the employer can facilitate the early return to work by the incremental resumption of duties, e. g. part time employment . Success in regard to the goals of returning the employee to work and increasing functionality can actually reduce the duration of treatment and at times the level of permanent disability. __________ 1 Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.

The method of treating industrial injury to the shoulder shall be as set forth below in the "Treatment Guideline for Shoulder Problems" as adopted by the Industrial Medical Council on May 15, 1997. SHOULDER PROBLEMS Introduction Shoulder problems are common among workers. The overall goals of the management of shoulder problems in workers is to identify and correct both environmental and personal factors that may be causing or aggravating the problem, while providing appropriate management of disability so that it leads to a return to productive work. Scope of the Guideline This guideline deals with the assessment and treatment of work-related shoulder problems, including tendinitis, bursitis, impingement syndrome, rotator cuff deficits, muscle injuries affecting the shoulder girdle, shoulder instability (including labral damage and acromioclavicular (AC) separation) and pectoral girdle nerve syndrome. Initial assessment to rule out serious shoulder problems is discussed, but definite diagnosis and treatment of serious disorders is beyond the scope of this guideline. This guideline does not deal with issues of legal causation or work-relatedness. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted parameters for the assessment and treatment of shoulder injuries. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed with these types of industrial conditions. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers will not fit the clinical conditions contemplated by a guideline. Symptom duration is defined as acute (< one month), subacute (one-three months) and chronic (> three months). For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with usual practices. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document no later than 6 months from the date of injury, whether further treatment is warranted and whether the injured worker has significant subjective and objective evidence of the condition not having plateaued. 1.0 Initial Assessment (First Month) 1.1 Purpose The purpose of the initial assessment is to differentiate occupational shoulder disorders secondary to chronic fatigue of neck and shoulder muscles from the specific overuse phenomena, such as tendinitis. It should also be noted that pain complaints in the neck, chest, cardiovascular system, liver, gallbladder or upper thoracic spine are frequently referred to the shoulder. Conditions considered in this guideline include, but are not limited to, the following examples: Sudden overload of a muscle tendon unit can create ruptures of various muscles about the shoulder. This is a relatively uncommon problem but disabling for varying periods when it occurs. The injury is usually defined within the first several days, largely based on physical examination. Instability of the shoulder may be associated with weakness and limited function. Specific definition of the problem, with early decision as to whether surgical reconstruction or specific rehabilitation is necessary, will hasten the return to normal function. The phrase "impingement syndrome" at times may replace less specific diagnoses such as bursitis or tendinitis. 1.2 Appropriate assessment methods 1.2.1 History and physical exam The history focuses on the nature of the injury, and the duration of the shoulder complaint. The work history may include awkward postures and/or a prolonged duration of similar work postures. Ask about a history of previous or contralateral shoulder problems. With pain complaint on the part of an individual claiming work injury, clear definition of the source of the injury should be made. Shoulder problems related to impingement syndrome, tendinitis and rotator cuff tears are usually the result of chronic overload over a long period of time yet they may occur on the basis of a single event. People with impingement syndrome will often complain of pain while sleeping on the affected side and inability to complete simple tasks. Visual inspection, range of motion, comparing the contralateral side, a manual test for shoulder strength, and palpation for joint tenderness or a possible defect should be performed on all injured workers. Musculotendinous injuries may be suspected by a history of weakness, joint tenderness and a palpable defect. Shoulder instability is often quite difficult to diagnose. Posterior subluxation of up to 50% and anterior subluxation of up to 33% may be a normal finding under general anesthesia. The tests to define instability include: apprehension tests drawer signs provocative tests such as the Sulcus sign, which is elicited by pulling downward the arm held at the side and noting the subacromial skin indentation. The impingement syndrome can be diagnosed by physical examination. Examination will often demonstrate an area of tenderness. This is especially noted when the arm is in 10 degrees of extension and internal rotation. This particular location allows the tuberosities to be palpable. Range of motion may be limited particularly in internal rotation and cross-body adduction. Passive motion through a 60 to 90 degree arc of flexion may be associated with crepitus as well as pain. Active elevation of the arm is usually more uncomfortable than passive elevation. 1.2.2 X-rays X-rays may be done on the initial medical evaluation if there is a specific history of injury, and/or the examining physician determines that x-rays are clinically necessary. (Mail Survey=4) (Consensus Panel=) [4] X-rays may suggest a history of instability. Plain x-rays may document an impression fracture in the posterior superior aspect of the humeral head (Hill-Sachs lesion). Stress x-rays may be useful to document occult instability. In individuals with impingement syndrome, plain x-rays which focus at the anterior acromion may note sclerosis and, in specific views such as the anterior scapula view, an increased "hooking" of the acromion. 1.2.3 Injections with local anesthetic to clarify or differentiate the diagnosis.(M=3) (C=4) [3] 1.3 Inappropriate initial assessment methods 1.3.1 Arthrography Plain arthrography for the evaluation of shoulder instability is inappropriate. CT/arthrography can be considered. [1] Plain arthrography may be appropriate for the evaluation of acute rotator cuff tears when the patient cannot undergo MRI. (M=1) (C=) [1] 1.3.2 Arthroscopy Arthroscopy is not routinely necessary for the detection of instability or rotator cuff status. (M=1)(C=)[1] 1.3.3 Specialized imaging tests Routine use of specialized imaging tests is not indicated. (M=1) (C=) [1] Chronic degenerative changes occur in the older age group in high frequency. Findings of degenerative changes on an imaging study may be incidental and not the reason for the injured worker's complaints. 2.0 Initial Treatment 2.1 Purpose The purpose of the initial treatment is to allow the injured worker to resume activities as soon as possible while not aggravating the shoulder symptoms. 2.2 Appropriate initial treatment methods 2.2.1 Education Appropriate education includes shoulder anatomy and the role of muscle weakness and fatigue in pain complaints. (M=4) (C=) [4] 2.2.2 Activity and environmental modifications Ergonomic modifications and changes of position are appropriate if possible and practical. (M=4)(C=)[4] Various EMG studies have documented a reduced muscle activity with ergonomic modification. Job modifications to avoid work activities such as overhead manual labor should be considered, especially for workers with repetitive-type injuries 2.2.3 Immobilization Primary shoulder dislocations, once relocated, should be treated immediately with immobilization for up to three to four weeks. (M=4) (C=4) [4] 2.2.4 Exercise 2.2.4.1 For occupational shoulder disorders, a strengthening and/or stretching program may be appropriate. 2.2.4.2 For individuals with shoulder instability, exercise programs to strengthen the muscles should be undertaken. (M=4) (C=) [4] Efficacy of various strengthening programs has not been documented by comparative studies except for cases of traumatic and non-traumatic subluxation. 2.2.4.3 For individuals with impingement syndrome, initial treatment should be in the form of isometric and/or resistive exercises (if tolerated by the injured worker), as well as mobilization exercises to the involved shoulder, focusing upon those muscles controlling the rotator cuff. (M=4) [4] 2.2.5 Medications (M=4) (C=) [3] Anti-inflammatory and pain medication may be indicated for shoulder injuries. Opioids may be necessary if the pain is refractory to treatment with non-opioid analgesics.(M=3)(C=4)[3] 2.2.6 Physical treatments Appropriate manual therapies include manipulation,or joint and soft tissue mobilization, supplemented by physical modalities and exercise. (M=4) (C=) [4] 2.2.7 Use of thermal modalities in conjunction with physical treatment may be useful. 2.2.8 Injections For impingement syndrome, bursitis and tendinitis specific local steroid injections (M=4) (C=4) [4] 2.2.9 Acupuncture (M=4) (C=2) [2] 2.2.10 Surgery Ruptures of major tendons should have surgical consideration for primary as should a significant tear of the rotator cuff or AC dislocation. (M=4) (C=) [4] 2.2.11 Shoulder girdle trigger point injections for specific indications may be useful, and, if so, should be for a trial of up to 3 sessions. (M=)(C=)[2] 2.3 Inappropriate initial treatments 2.3.1 Surgical treatments for tendinitis, bursitis, acromial clavicular subluxation (M=1) (C=) [1] 2.3.2 Proximal biceps ruptures often need not be repaired surgically. Function is often just as good with or without repair.M=1)(C=)[1] 2.3.3 Total immobilization after 1 week is inappropriate for most shoulder injuries. (M=1) (C=) [1] 2.3.4 Steroids for shoulder instability (M=1) (C=) [1] 2.3.5 Arthroscopic stabilization of the shoulder has not been confirmed to give greater stability than open shoulder stabilization surgery.(M=1)(C=)[1] 2.3.6 Trigger point injections unless a specific rationale can be presented. (M=1) (C=) [1] 2.4 Case management Management during the first 4 weeks of treatment will be determined by the clinician's evaluation of the injured worker's response to therapy. Generally, re-evaluation of the problem, determination of treatment effectiveness and work status should be performed every 1-2 weeks until return to modified or full work is achieved. At each visit, the initial diagnosis should be confirmed or modified and the treatment plan adjusted if necessary. If symptoms continue to increase despite adequate conservative therapy, or if there is significant disability due to pain, referral to a provider trained and experienced in the evaluation and treatment of occupational disorders is warranted in the initial treatment phase. Once the acute pain is controlled, the treatment should focus on progressive rehabilitative exercises to increase strength and endurance, and activity modification. This approach minimizes the chance of recurrence once normal occupational duties are resumed. 3.0 Secondary Assessment (after first month) 3.1 Purpose The purpose of reassessment is to determine the reason for delayed recovery in injured workers who have not experienced functional improvement after appropriate initial treatment. 3.2 Appropriate secondary assessment methods (for clinical indications as noted) 3.2.1 Objective testing (strength and range of motion) of status of rehabilitation may be indicated for individuals with findings of impingement syndrome. (M=4) (C=) [4] 3.2.2 Injections with local anesthetic to clarify pain issues (M =4) (C=) [4] 3.2.3 Specialized imaging tests A shoulder arthrogram may be useful when an MRI is inconclusive or contraindicated. (M=4) (C=) [3] 3.2.4 If an arthrogram is contraindicated, an MRI may be appropriate. (M=4) (C=) [4] 3.2.5 Ergonomic evaluation may be indicated if findings suggest that physical work factors may be contributing to delayed recovery or frequent exacerbation of the patient's condition. (M=4) (C=) [4] 3.3 Inappropriate secondary assessment methods 3.3.1 Psychological evaluation (M=1) (C=) [1] 4.0 Secondary Treatment 4.1 Purpose The purpose of secondary treatment is to cure or relieve the effects of the injury of the worker who remains refractory to primary treatment efforts. 4.2 Appropriate secondary treatment methods (for the specific clinical indications as noted) 4.2.1 Progressive active strengthening and stretching programs with documentation of functional progress. (M=4) (C=) [4] 4.2.2 Up to a maximum of three steroid injections into the subacromial space for individuals with the diagnosis of impingement.

Consultation should include a complete evaluation and recommendations for treatment and return to appropriate work. If psychosocial issues are judged to contribute to delayed recovery or heightened disability, it may be appropriate to have a psychiatric evaluation. If the condition becomes chronic or disabling despite full conservative treatment including appropriate medical, rehabilitative, and ergonomic interventions (and surgery if indicated), the injured worker should be evaluated for permanent disability. 5.0 Prevention 5.1 Purpose The purpose of prevention is to avoid reoccurrence of shoulder pain complaints. 5.2 Appropriate preventive measures 5.2.1 Exercises to maintain/improve strength, range, and endurance.

The method of treating industrial injury to the knee shall be as set forth below in the "Treatment Guideline for Knee Problems" as adopted by the Industrial Medical Council on March 20, 1997. KNEE PROBLEMS Introduction Management of knee problems in injured workers includes consideration of environmental and personal factors which may be causing or aggravating the problem, as well as providing treatment that leads to a return to productive work. Scope of the guideline: This guideline deals with the assessment and treatment of knee problems, including 1) articular surface damage, 2) bone damage, 3) synovial and capsular damage 4) ligament injuries, 5) patellofemoral tracking (chondromalacia), 6) meniscal injuries and 7) loose bodies in the knee. Knee problems can be acute (< 4 weeks), subacute (1 to 3 months), or chronic (> 3 months). Initial assessment to rule out serious knee problems is discussed, but definite diagnosis and treatment of serious disorders is beyond the scope of this guideline. This guideline does not deal with issues of legal causation or work-relatedness. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted parameters for the assessment and treatment of knee injuries. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed with these types of industrial conditions. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers will not fit the clinical conditions contemplated by a guideline. For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with the Official Medical Fee Schedule. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document no later than 6 months from the date of injury, whether further treatment is warranted and whether the injured worker has significant subjective and objective evidence of the condition not having reached maximum medical improvement (i.e. Permanent and Stationary status). 1.0 Initial Assessment 1.1 Purpose The purpose of the initial assessment is to define the structural abnormality, in particular knee stability and intra articular abnormalities. Initial evaluation of an acute knee injury focuses on avoiding missed diagnoses. Early diagnoses of repairable abnormalities will speed return to work. 1.2 Appropriate initial assessment methods 1.2.1 History and physical The history focuses on defining the nature of the injury, the duration of the knee complaint, and the past history of effusion. A history of previous knee injuries or other workplace injuries is important. Pain in the knee may be from the hip, the back, the thigh or the lower leg. Clinical diagnosis of knee problems can usually be made on history and physical examination with the help of x-rays. The presence of hemarthrosis suggests a more serious injury. Aspiration of a tense knee effusion may reduce pain and allow a more appropriate evaluation on physical examination. Injection of a local anesthetic may also be indicated. The usual complaint of individuals with ligament insufficiencies is 'giving away'. Definition of the problem by physical examination is the first step in appropriate care. Appropriate tests should be used to identify ligamentous incompetence, disruption of a meniscus, articular surface irregularity and other soft tissue injury. Many injuries such as meniscus and ligament damage can be established by physical examination and may not require further tests. 1.2.2 X-rays (Mail Survey =4) (Consensus Panel=) [4] Appropriate indications for radiography in acute knee injuries include: Tenderness at the head of fibula Isolated tenderness of the patella (no other bone tenderness of the knee) Inability to fully extend the knee Inability to weight bear both immediately and in the provider's office (four steps regardless of limping) Tense effusion Acute direct trauma to the knee Inability to flex beyond 90 degrees 1.2.3 Diagnostic arthroscopic examination Arthroscopic examination may be necessary on very rare occasions when clinical evaluation is not diagnostic. (M=4) (C=) [2] Arthroscopy allows examination of the under surface of the patella, meniscus tears, cruciate ligament status, synovitis, loose bodies, and the status of the tibial and femoral articular surfaces. 1.2.4 Vascular studies Vascular studies are indicated if the injury is associated with vascular disruption/damage, a secondary vascular complication, or a dislocation of the knee.(M=4) (C=4) [4] 1.3 Inappropriate initial assessment methods 1.3.1 MRI/CT MRI/CT is not usually appropriate at the initial evaluation or within the first month. (M=1) (C=) [1] Exceptions include suspected subarticular stress fracture or bone bruise, any evidence of a mass, a tear of the patellar tendon or a locked knee. 1.3.2 Arthrogram An Arthrogram is not usually appropriate at the initial evaluation or within the first month. (M=1) (C=) [1] 2.0 Initial Treatment 2.1 Purpose The purpose of the initial treatment is to return the worker to their pre-injury status and to facilitate sustained return to work. 2.2 Appropriate initial treatment methods may include: 2.2.1 Aspiration of a tense, painful effusion. (M=4) (C=) [4] 2.2.2 Ice, compression and elevation of a painful knee. Immobilization of an unstable knee, including functional bracing. (M =4) (C=) [4] 2.2.3 Initial treatment for primary patellofemoral dislocation includes immobilization. (M=4) (C=4) [4] 2.2.4 Medications 2.2.4.1 Anti-inflammatory and non-narcotic analgesic medications (M=4) (C=) [3] 2.2.4.2 Narcotic analgesics are usually not required. (M=1) (C=) [2] 2.2.5 Physical medicine modalities may enhance early rehabilitation (M=4) (C=) [4] 2.2.6 Progressive exercise program (M=4) (C=4) [4] Progressive exercises should be performed to prevent weakness, stiffness and other forms of deconditioning. 2.2.7 Manual medicine/modalities (M=4) (C=) [4] 2.2.8 Surgery (M=4) (C=) [4] Surgery may be needed to remove loose bodies or to correct major soft tissue or bony disruption. 2.2.9 Ligament injuries Immediate repair of anterior cruciate ligaments in many situations is not necessary. (M=1) (C=) [1] Primary, multiple structural repairs require additional documentation because of a less predictable outcome. (M=1) (C=) [1] Isolated tears of the medial collateral and/or lateral collateral ligament usually do not require surgical repair. (M=1) (C =) [1] Although the prognosis is not good, combined repair of cruciate and lateral collateral ligaments may be needed. (M=1) (C=) [1] 2.3 Inappropriate initial treatments 2.3.1 A TENS unit is inappropriate in the initial phase. (M=1) (C =) [1] 2.3.2 Psychotropic medications are seldom needed. (M=1) (C=) [1] 2.4 Case management Management during the first 4 weeks of treatment will be determined by the clinician's evaluation of the injured worker's response to therapy. Generally, re-evaluation of the problem, determination of treatment effectiveness and work status should be performed every 1-2 weeks until return to modified or full work is achieved. At each visit, the initial diagnosis should be confirmed or modified and the treatment plan adjusted if necessary. If symptoms continue to increase despite adequate conservative therapy, or if there is significant disability due to pain, referral to a provider trained and experienced in the evaluation and treatment of occupational disorders is warranted in the initial treatment phase. Once the acute pain is controlled, the treatment should focus on progressive rehabilitative exercises to increase strength and endurance, and activity modification. This approach minimizes the chance of recurrence once normal occupational duties are resumed. 3.0 Secondary Assessment 3.1 Purpose The purpose of reassessment is to determine the reason for delayed recovery in patients who have not functionally improved. It is often difficult initially to assess the severity of the damage and/or instability. Therefore, reassess any individual who remains symptomatic after a trial of rehabilitation. 3.2 Appropriate secondary assessment methods, if clinically indicated, include: 3.2.1 Use of mechanical devices to test strength and stability. Appropriate tests may be performed with initiation of the rehabilitation process and particularly post operatively and may be necessary to be repeated upon conclusion of rehabilitation. (M=4) (C =) [3] Special equipment which isolates the knee and measures strength may be helpful. 3.2.2 Diagnostic imaging testing may be appropriate if the worker remains symptomatic, the diagnosis elusive and/or surgery is planned. (M=4) (C=) [4] Testing may include an x-rays, MRI, CT, and arthrogram. Clinical indications: Joint instability or obvious ligamentous damage determined by the physical exam that is not responsive to conservative treatment and the decision to do arthroscopy has not yet been made. Post-traumatic hemarthrosis or persistent effusion (over 4 weeks). Acute trauma with unexplained persistent pain of over four weeks that is not responsive to conservative treatment and the decision to do arthroscopy has not yet been made. Findings suggestive of a defect in the alignment of the patella. Indications previously mentioned under initial evaluation (suspected subarticular stress fracture or bone bruise, any evidence of a mass, or tear of the patellar tendon). 3.2.3 Functional capacity evaluation may be indicated in situations of ligament reconstruction or other major knee surgery. [3] 3.3 Inappropriate secondary assessment methods 3.3.1 EMG unless muscle weakness is thought to be secondary to nerve damage. (M=1) (C=) [1] 3.3.2 Vascular studies are not indicated unless there is associated vascular disruption/damage or a secondary vascular complication. (M=1) (C=) [1] 3.3.3 Bone scan (M=1) (C=) [1] 4.0 Secondary Treatment 4.1 Purpose The purpose of secondary treatment is to help the injured worker who is slow to recover. 4.2 Appropriate secondary treatment methods (for the specific clinical indications as noted) 4.2.1 Progressive physical exercise program 4.2.1.1 Individuals without full range of motion and strength can benefit from a progressive exercise program. (M=4) (C=) [4] 4.2.1.2 Rehabilitation therapy is important following surgery. (M =4) (C=) [4] 4.2.1.3 Functional bracing for unstable knees under non-surgical care. (M=) (C=4) [4] 4.2.2 Surgery 4.2.2.1 Arthroscopic surgery may be indicated if a clinically significant, surgically correctable abnormality is documented. (M=4) (C=) [4] 4.2.2.2 Reconstruction of ligaments is best done after appropriate rehabilitation to restore range of motion. (M=) (C=4) [4] 4.3 Inappropriate secondary treatments 4.3.1 Surgery 4.3.1.1 Total removal of the meniscus (M=1)(C=) [1] The meniscus is an important component of knee mechanism. Even a mild degenerative meniscus is more useful than an absent meniscus. Excision of the total meniscus leads to a significant amount of problems. The modern approach is to remove as little as possible and try for repair in the younger individual. 4.3.1.2 Multiple ligament repairs performed at the same time as repairs to the meniscus (M=1) [1] Multiple ligament repairs performed at the same time meniscus repairs may lead to a stiff joint. 4.3.1.3 Collateral ligament repair for injuries without instability (M=1) (C=) [1] 4.3.2 Prolonged immobilization (M=1) (C=) [1] 4.3.3 Multiple steroid injections into the knee joint (> 3), or into the ligament or tendon is rarely indicated. Direct steroid injections in the ligament or tendons of the knee is rarely indicated. Steroid injections of the bursae of the knee may be indicated. (M=1) (C=) [1] 4.3.4 Routine prescription of pain or sedative medication is not recommended and when prescribed for severe pain, should be limited in duration and quantity. (M=1) (C=) [1] 4.4 Case management If the injured worker has not resumed near normal work duties after 8 weeks of full conservative therapy including adherence to a graded exercise program, a referral to a physician trained and experienced in the evaluation and treatment of occupational disorders or an orthopedic surgeon is recommended. Consultation should include a complete evaluation and recommendations for treatment and return to appropriate work. If the condition becomes chronic or disabling despite full conservative treatment including appropriate medical, rehabilitative, and ergonomic interventions (and surgery if indicated), the injured worker should be rated for permanent disability. If psychosocial issues are judged to contribute delayed recovery heightened disability, it may be appropriate to have a psychiatric evaluation. 5.0 Prevention 5.1 Purpose The purpose of preventive measures is to avoid reoccurrence of the knee problems. 5.2 Appropriate preventive measures 5.2.1 Exercises which maintain/improve strength, range, and endurance (M=4) (C=) [4] 5.2.2 Functional bracing for ACL/PCL unstable knees (M=) (C=4) [4] 5.3 Inappropriate preventive measures 5.3.1 Prolonged total immobilization.

The method of treating industrial injury to the elbow shall be as set forth below in the "Treatment Guideline for Elbow Problems" as adopted by the Industrial Medical Council on May 15, 1997. ELBOW PROBLEMS Introduction Elbow problems are a common musculoskeletal disorder. Acute 'strain' or blunt trauma may precipitate elbow problems such as medial and lateral epicondylitis, bursitis, nerve entrapment, and tendinitis. Scope of this guideline: This guideline is intended for use in the diagnosis and management of working aged people with a primary complaint of elbow or extensor forearm pain and whose occupational activities put them at risk for elbow problems. The condition of lateral epicondylitis will be used throughout this guideline as an example. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted parameters for the assessment and treatment of elbow problems. The guidelines are intended to assure appropriate and necessary care for injured workers diagnosed with these types of industrial conditions. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers will not fit the clinical conditions contemplated by a guideline. Symptom duration is defined as acute (< one month), subacute (one - three months) and chronic (> three months). For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. This guideline does not address the evaluation and management of chronic elbow problems including chronic pain syndrome. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with the usual practices. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document no later than 6 months from the date of injury, whether further treatment is warranted and whether the injured worker has significant subjective and objective evidence of the condition not having plateaued. 1.0 Initial Assessments (First Month) 1.1 Purpose The purpose of the initial assessment is to establish a specific diagnosis. For the diagnosis of occupational elbow problems, a work-related etiology should be established, and relevant non-occupational home, hobby and sports activities should be ruled out as contributing or causative factors. When considering diagnoses other than those involving the elbow, the provider should refer to the appropriate treatment guideline. 1.2 Appropriate initial assessment methods 1.2.1 History and physical examination A detailed history addressing all pertinent complaints should be obtained including the characteristics of the pain, its onset and location, radiation, provocative and relieving factors. Hand dominance should be recorded. Any antecedent symptoms, trauma, fall, or new activities should be documented. Typical symptoms of lateral epicondylitis include pain in the lateral aspect of the elbow with pain or burning radiating to the forearm (and occasionally proximal radiation). There may be loss of grip strength due to forearm pain with hand grip. Pain is usually insidious in onset but may be provoked by an acute trauma or strain. Initial complaints may be vague, such as a dull forearm ache. Any history of similar symptoms in the past, including diagnosis and treatment strategies should be recorded. Documentation of probable work-relatedness should be made, including the injured worker's job title and occupational tasks. Specific attention should be directed towards confirming occupational risk factors such as repetitive, sustained or forceful wrist dorsiflexion, power grip, exposure to vibration, repetitive extended elbow reach with forceful pulling, and repetitive pronation and supination of the forearm against resistance. Record any recent changes in work duties, overtime, and work station or process design. Document any relationship of the symptoms to the work day, work week, particular task, and the use of any specific tools and equipment. A history of lost work days due to these symptoms, and other work-related musculoskeletal diagnoses should be recorded. Any functional impairment or current activity or work modifications should be noted. Rule out non occupational activities that could be causing or aggravating the condition, such as activities that require gripping or hyperextending the wrist. Olecranon bursitis may be secondary to systemic illness. Past medical history and current health status should be documented. Routine screening questions for cervical or shoulder pain or injury should be asked. A physical examination should be performed with documentation of the following findings: Inspection for: deformity, swelling or erythema. Provocative maneuvers: such as the presence or absence of pain with resisted dorsiflexion of the wrist, passive wrist flexion with the elbow in full extension, resisted supination of the forearm, and Tinel's sign. Range of motion: elbow flexion and extension, pronation and supination, wrist flexion and extension. Note any flexion contracture deformity of the elbow. Palpation: Document the presence or absence of the following: elbow deformity, tenderness, heat or crepitus (including olecranon process and medial epicondyle). Also check the forearm for deformity, heat or tenderness. Muscle strength testing of the entire upper extremity should be performed as relevant. Appropriate distal extremity exam should include neurological testing. A routine examination of the shoulder, neck, and wrist, and hand (palpation, range of motion, strength testing) should be performed. A differential diagnosis should be considered at this point: such as radiculopathy, or shoulder pathology with referred pain. 1.2.2 Diagnostic imaging (M=4) [4] Radiographic studies of the elbow and forearm should be obtained when clinically indicated. As a rule, the diagnosis of elbow problems does not require an imaging study. 1.2.3 Laboratory studies Appropriate laboratory studies should be considered if there is evidence of an infectious or diffuse inflammatory process as a contributing or causative factor. (M=4) [4] 1.2.4 Electromyography/Nerve conduction studies (EMG/NCS) Nerve conduction studies may be indicated for elbow problems associated with neurological deficits. (M=4) [4] 1.2.5 Aspiration of the olecranon bursa is not routinely indicated unless there is suspicion of infection or metabolic disease. 1.3 Inappropriate initial assessment methods 1.3.1 Routine diagnostic imaging (M=2) (C=1) [1] 1.3.2 Routine laboratory studies (M=2) (C=1) [1] 1.3.3 Routine nerve conduction studies (M=2) (C=1) [1] 1.3.4 Arthroscopy, arthrogram (M=1) [1] 1.3.5 Ultrasound (M=1) [1] 1.3.6 MRI scan (M=1) [1] 2.0 Initial Treatment 2.1 Purpose The purpose of the initial treatment is to reduce, symptoms, optimize healing/function and increase work with appropriate modifications to minimize the risk factors that contributed to the injury. 2.2 Appropriate initial treatments 2.2.1 Education (M=4) [4] All injured workers should receive instruction concerning the nature of their condition, its risk factors, preventive measures and goals of initial therapy. This information should be provided by the physician or by a Physical or Occupational Therapist as part of a referral for treatment (see Physical Treatments and Passive Modalities section). The injured worker should be instructed on how to eliminate or modify any aggravating non-occupational activities and sports during treatment. 2.2.2 Ergonomic modification (M=4) [4] Work restrictions or modifications which reduce the injured worker's exposure to the etiologic or aggravating activity are of central importance. Examples of such restrictions include preclusion from or reduction in time performing tasks requiring repetitive, sustained or repetitive forceful wrist or hand activities, repetitive elbow motion, prolonged elbow positioning or prolonged exposure to vibration. Be specific about work preclusions and avoid terms such as "light duty". The physician should discuss with the employer appropriate tasks for the injured worker to perform while undergoing treatment, and to discuss task modification once the injured worker resumes full and unrestricted employment, in order to reduce the chance of recurrence. Initial treatment of elbow problems need not involve lost work time. A job evaluation by an experienced specialist trained in ergonomics may be considered in order to identify appropriate modifications to the tasks, tools, or workstation. 2.2.3 Medications a. Nonsteroidal antiinflammatory agents can be used. (M=3) (C=4) [3] The choice of specific drug is discretionary. The injured worker should be screened for contraindications to their use and warned of the common potential side-effects. b. Acetaminophen is an analgesic which may be used as an adjunct or alternative to NSAIDs. (M=3) (C=4) [3] c. Opioids may be necessary if the pain is refractory to treatment with non-opioid analgesics. (M=3) (C=4) [3] 2.2.4 Physical treatments and passive modalities If there is no improvement after 2 weeks the treatment should be modified. a. Use of thermal modalities in conjunction with physical treatment may be useful. b. Physical treatments for pain management splinting and/or functional retraining and instruction in a graded exercise program. (M=4) [4] Appropriate exercises may include, but are not limited to,: 1) gentle muscle stretching; 2) flexibility; and 3) graduated strengthening. Care should be taken while incrementing exercises so that the condition is not aggravated. c. Appropriate manual therapies may include manipulation, or joint or soft tissue mobilization, supplemented by physical modalities and exercise.[3] d. Acupuncture Use of acupuncture in the first 4 weeks of treatment as a part of an overall treatment plan. (C=3) [2] 2.2.5 Protective devices The use of an elbow and/or wrist support for immobilization may be indicated for a brief period. (M=4) [4] The use of a splint at work must be carefully considered as it may put the injured worker at risk for further musculoskeletal injury by forcing the adoption of awkward compensatory postures. A forearm strap can be aggravating in the acute stage so its use should be individualized. It is contraindicated in the presence of nerve compression symptoms. Night splinting may be indicated for nerve entrapment syndromes. 2.2.6 Local corticosteroid injection Local corticosteroid injections of the myofascial areas or bursae may be appropriate, especially if the pain is moderate to severe. (M =4) [4] Before the injection, it is important to be aware that the olecranon bursa may be the site of infection. In such an instance, an steroid injection would be contraindicated. 2.3 Inappropriate initial treatments 1. Medications-Systemic corticosteroids, and/or muscle relaxant. (M=1) [1] 2. Exclusive use of passive modalities (M=1) (C= 1) [1] 3. Surgery is rarely indicated (M=1) [1] 2.4 Case management Management during the first 4 weeks of treatment will be determined by the clinician's evaluation of the injured worker's response to therapy. Generally, re-evaluation of the problem, determination of treatment effectiveness and work status should be performed every 1-2 weeks until return to modified or full work is achieved. At each visit, the initial diagnosis should be confirmed or modified and the treatment plan adjusted if necessary. If symptoms continue to increase despite adequate conservative therapy, or if there is significant disability due to pain, referral to a provider trained and experienced in the evaluation and treatment of occupational disorders is warranted in the initial treatment phase. Once the acute pain is controlled, the treatment should focus on progressive rehabilitative exercises to increase strength and endurance, and activity modification. This approach minimizes the chance of recurrence once normal occupational duties are resumed. 3.0 Secondary Assessment 3.1 Purpose Most workers with elbow injuries will respond to initial treatment with reduction of pain and near or full return to occupational duties. The purpose of secondary assessment after conservative treatment is to determine the cause of delayed recovery. This may be due to misdiagnosis, non-compliance with the treatment regimen, inappropriate work modifications or other perpetuating factors. A reconsideration of the initial diagnosis is necessary at this stage and a differential diagnosis should be reviewed: cervical radiculopathy, shoulder pathology with referred pain and nerve entrapment. Work status and disability should be determined. 3.2. Appropriate secondary assessment methods 3.2.1 History and physical examination An interval history and physical examination should be performed. Particular attention should be paid to compliance with and response to therapy. The development of any new symptoms should be documented as well as side effects of treatment modalities. The appropriateness of the prescribed work restrictions should be reviewed, including how they were accommodated by the employer. 3.2.2 Diagnostic imaging Radiographic studies of the elbow and forearm may be considered if, on re-evaluation, the physician suspects morphologic pathology. (M=4) [4] The use of MRI and arthrography is rarely indicated except for the evaluation of intraarticular pathology. 3.2.3 Laboratory studies Laboratory studies may be performed if there is evidence of an infectious or diffuse inflammatory process as a contributing pathology. (M=4) [4] 3.2.4 EMG/NCS Electrodiagnostic studies should be considered if there is clinical evidence of nerve entrapment or cervical radiculopathy as alternative diagnoses. (M=4) [4] 3.3 Inappropriate secondary assessment methods 3.3.1 Arthroscopy or arthrogram (M=1) [1] 3.3.2 Ultrasound (M=1) [1] 4.0 Secondary Treatment 4.1 Purpose Secondary treatment options should be selected on the basis of the injured worker's response to initial conservative treatment for 4 weeks. If specific causes of delayed recovery are determined, they may be addressed in this phase. The purpose of secondary treatment is to reduce symptoms and optimize the return to normal arm function and a graded resumption of full and unrestricted employment. 4.2 Appropriate secondary treatments 4.2.1 Continued conservative management a. Occupational activities should be advanced and modifications to the work environment reviewed to prevent exacerbation of symptoms. (M=4) [4] An ergonomic assessment of the workstation may be necessary to facilitate this. b. The injured worker's progress in the progressive exercise program should be reviewed. (M=4) [4] c. Medication NSAID's or acetaminophen may be used periodically. Non steroidal anti-inflammatory agents should be discontinued as soon as possible. (M=4) [4] A trial of 6-8 weeks maximum is recommended. They may be re-instituted briefly for symptom flare. Periodic acetaminophen may be used also. Opioids may be necessary if the pain is refractory to treatment with non-opioid analgesics. (M=3) (C=4) [3] Use of thermal modalities in conjunction with physical treatment may be useful. d. Bracing or supports may be continued if beneficial. (M=4) [4] It may be uncomfortable and exacerbate symptoms, especially if worn inappropriately (i.e. overlying the trigger point). e. Various manual and/or passive modalities may be used but, not standing alone as a sole treatment. [3] f. Acupuncture (M=3) (C=3) [3] g. Biofeedback [3] 4.2.2 Local injection including corticosteroids during the secondary phase may be indicated. If there is partial or transient relief with the first injection, local injections may be repeated (up to a total of three). (M=3) (C=4) [3] Complications of injection include local infection, hematoma, skin discoloration and subcutaneous fat atrophy. Injection must be accompanied by the activity and workplace modifications discussed above. 4.2.3 Surgical referral Surgical consultation is recommended if any of the following criteria are met: (C=4) [4] a. Failure of conservative treatment and indication of a surgically correctable condition. 4.3 Inappropriate secondary treatments 4.3.1 Medications. Systemic corticosteroids and/or delivery of medications by ionto or phonophoresis. (C=1) [1] 4.4 Case management If the injured worker has not resumed near normal work duties after 8 weeks of full conservative therapy including adherence to a graded exercise program, a referral to a physician trained and experienced in the evaluation and treatment of occupational disorders or an Orthopedic or Hand Surgeon is recommended. Consultation should include a complete evaluation and recommendations for treatment and return to appropriate work. If psychosocial issues are judged to contribute to the disability, it may be appropriate to have a psychologic evaluation. If the condition becomes chronic or disabling despite full conservative treatment including appropriate medical, rehabilitative, and ergonomic interventions (and surgery if indicated), the injured worker should be evaluated for permanent disability. 5.0 Primary References 1.

The method of treating industrial injury to the hand and wrist shall be set forth below in the "Treatment Guideline for Problems of the Hand & Wrist" as adopted by the Industrial Medical Council on May 15, 1997. PROBLEMS OF THE HAND AND WRIST Introduction Conditions affecting the hand and wrist are common among workers with tasks requiring intensive use of the upper extremity. Evaluation can be difficult, given the anatomical and functional complexity of the region. However, a systematic assessment of upper extremity symptoms contributes to accurate, timely and cost-effective diagnosis and treatment. Scope of this guideline This guideline is intended for use in the diagnosis and management of hand and wrist tendinitis, de Quervain's tenosynovitis, nerve entrapment syndromes and wrist pain in working aged adults whose occupational activities put them at risk for these problems. Guidelines for initial assessment (first 4 weeks) and subsequent secondary assessment (1 to 3 months) are presented here. This guideline does not address all conditions causing hand & wrist symptoms such as fractures. This guideline does not deal with legal issue of causation or work relatedness. Treatment guidelines are designed to assist providers by providing an analytical framework for the evaluation and treatment of the more common problems of injured workers. These guidelines are educational and descriptive of generally accepted practices for the assessment and treatment of wrist pain, nerve entrapment syndromes, de Quervain's tenosynovitis and hand and wrist tendinitis. Due to the many factors which must be considered when providing quality care, health providers shall not be expected to always provide care within the stated guidelines. Treatment authorization, or payment for treatment, shall not be denied based solely on a health care provider's failure to adhere to the IMC guideline. The guidelines are not intended to be the basis for the imposition of civil liability or professional sanctions. They are not intended to either replace a treating provider's clinical judgment or to establish a protocol for all injured workers with a particular condition. It is understood that some injured workers will not fit the clinical conditions contemplated by a guideline. Symptom duration is defined as acute (< one month), subacute (one - three months) and chronic (> three months). For the purpose of this document, a provider is defined as any health care provider acting within the scope of his/her practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician. All health care providers acting within the scope of their practice, including those to whom an injured worker has been referred or whose treatment has been prescribed by a treating physician, shall be allowed to bill and be reimbursed in accordance with usual practices. A provider may vary from these guidelines, if in his or her judgment, variance is warranted to meet the health care needs of the injured worker and that variance remains within the standards of practice generally accepted by the health care community, and the provider documents the need for the variance in the evaluation report or the medical treatment record in the manner that is generally accepted by the health care community. Not every medical situation can be addressed in these regulations and medical standards change constantly. The documentation required of the provider is necessary to monitor and explain the use of variances. In all cases, the provider shall document no later than 6 months from the date of injury, whether further treatment is warranted and whether the injured worker has significant subjective and objective evidence of the condition not having plateaued. 1.0 Initial Assessment (First month) 1.1 Purpose The purpose of the initial assessment of hand and wrist is to establish specific diagnosis(es). These may include hand and wrist tendinitis/ tenosynovitis, and nerve entrapment syndromes. An additional purpose of the initial assessment is to identify and document any medical, mechanical or psychosocial factors which are contributing to the symptoms and/or may influence the response to treatment. At the discretion of the physician, a shorter, less detailed evaluation may be acceptable. 1.2 Appropriate Initial Assessment Methods 1.2.1 History As appropriate, the initial history should contain the following basic information for the medical record: the injured worker's age, hand dominance, job description, pre-injury limb function, daily physical activities, previous limb injuries and relevant medical/surgical history. A detailed symptom history may be documented, including characteristics of pain (type, location, duration, severity, radiation), associated symptoms, exacerbating and relieving movements and other factors, and the impact on function at home or work. Information concerning recent trauma and previous diagnostic or treatment procedures (including home treatments) may be obtained. The initial evaluation must address the possible presence of mechanical factors which are causing, aggravating, or precipitating the painful condition, including occupational and nonoccupational physical activities. The relationship of the symptoms to the performance of specific activities may be sought and recorded (e.g. symptoms experienced during work tasks, time off, hobbies, sports or other activities). Inquiry into any history of similar symptoms, previous diagnoses and treatments should be made. The initial history may also note any psychosocial factors which are potentially relevant to the clinical course of the condition, including work status, economic or psychological effects of the condition, and unresolved litigation or workers' compensation issues. If tendinitis/tenosynovitis is suspected, ask about the typical symptom of localized pain aggravated by direct pressure over or use of the affected muscle-tendon unit. The discomfort may radiate in a proximal or distal direction when force is applied to the tendon. Initially intermittent discomfort may be experienced, but can progress to become a persistent burning or sharp pain. Associated symptoms descriptive of triggering, crepitus, weakness and/or limited motion may be present. An example of a common tenosynovitis is de Quervain's tenosynovitis. The classic presentation of this condition is pain over the radial styloid; local swelling may also be present. The injured worker may describe symptoms of proximal and distal radiation of pain from this site and/or weakness of pinch or grip strength. The discomfort is exacerbated by ulnar wrist deviation and thumb flexion and adduction. Triggering may be present if the condition is chronic. If Nerve Entrapment Syndromes are suspected, inquire about the typical symptoms - insidious onset of hand paresthesias in the thumb, index, middle and/or radial aspect of ring fingers (median nerve inervation). Many injured workers will describe paresthesias more diffusely, in all fingers. Nocturnal paresthesias, if present, are particularly characteristic. Dull aching hand pain, subjective grip stiffness, weakness of grip or pinch, hand clumsiness and impaired manual dexterity are other presenting complaints. Symptoms may be vague or atypical, and non-specific wrist and hand symptoms in a manual worker should prompt consideration of CTS in the differential diagnosis. Self-administered hand symptom diagrams have been developed and may be useful in obtaining a detailed description of the distribution and severity of hand symptoms. They may serve as an aid in the history and physical examination. Documentation of activities as they relate to hand should be made, including the injured worker's job title and a description of tasks performed Note the use of each hand in work tasks. Record any recent changes in work duties, overtime, tool design and patterns of tool use or any loss of function, lost work time, or limitation of activity or modification of work due to symptoms. Work station design and adjustability, as well as any prior ergonomic assessment or recent modifications should be noted. Record the onset of symptoms in relation to the work day, work week and specific work tasks or equipment. Any history of previous work related musculoskeletal diagnose be recorded. Consider non-occupational activities and medical conditions that could cause or aggravate the presenting symptoms, i.e. hobbies, child handling, sports, and musical pursuits. When the clinical picture is confusing, screening questions should be asked about neck or other upper extremity injury or symptoms. In the case of an atypical presentation of nerve entrapment syndromes, other pathologies may be considered. These include: a. Cervical radiculopathy (especially C-6 or C-7) b. Neurovascular compression syndromes such as: Thoracic outlet syndrome Anterior scalene syndrome Costoclavicular syndrome Hyperabduction syndrome c. Other nerve compression syndromes: Radial nerve entrapment: Posterior interosseus entrapment, radial tunnel syndrome Ulnar nerve entrapment: At the elbow or in the Canal of Guyon Median nerve entrapment: Pronator teres syndrome, anterior interosseus syndrome d. Other conditions: Reflex sympathetic dystrophy, Raynaud's syndrome inflammatory, or degenerative joint diseases. Past medical history and current health status may be elicited and should be evaluated for possible clinical significance. These may include, but are not limited to: 1. Pregnancy 2. Diabetes mellitus 3. Hypothyroidism 4. Fluid retention / edema 5. Rheumatoid arthritis/degenerative joint disease of the wrist and hand 6. Gout 1.2.2 The initial physical examination will be focused upon the affected part but may also include a basic examination of both upper extremities, including the cervical spine, shoulder, upper arm, elbow, forearm and hand. General physical signs of underlying medical diseases may also be sought. This approach can identify more distant causes of pain such as cervical radiculopathy and/or non-work related disorders contributing to or causing the symptoms (e.g. myxedema). Examination of the contralateral extremity is useful for comparison and to identify any bilateral abnormalities. Basic elements of the wrist and hand examination may include: Inspection for swelling, erythema, thenar muscle atrophy, nodules, signs of trauma, surgical scars, arthritic bony changes, soft tissue masses, hyper/hypohydrosis, altered hair pattern, edema, cyanosis, guarding, abnormal posture or other deformities of joints or soft tissues. Palpation of osseous and soft tissue structures for tenderness, swelling, skin temperature asymmetry, abnormal sweating, synovial thickening, masses, ganglion cysts, nodules, bony deformity, pulses, muscle spasm, myofascial trigger points, or crepitus. Range of motion testing as appropriate of neck, shoulders, elbows, forearm, wrist and fingers for pain, range limitation, crepitus at joint or tendon sheath, tendon triggering or locking. On range of motion testing of tendinitis/tenosynovitis, the focal discomfort is typically increased by passive stretching of the affected tendon, especially with composite range of motion testing. Associated symptoms descriptive of triggering, crepitus weakness and/or limited motion may be present. Muscle strength testing may include such specific areas as the abductor pollicis brevis, resisted palmar abduction of the thumb for nerve entrapment syndromes. Serial grip strength measurements with a dynamometer may be useful in following clinical progress of tendinitis/tenosynovitis. Provocative maneuvers for tendinitis, muscle strain, tendon subluxation, joint/ligament instability, nerve entrapment, and if warranted, thoracic outlet syndrome. Consider more specific tests such as: Tinel's - performed by percussing lightly along the projection of the given nerve, Phalen's - sustained wrist flexion for 60 seconds, and Finkelstein's - pain over the radial styloid is augmented by gentle passive ulnar deviation of the wrist with the thumb held adducted in the palm. It should be remembered that positive results from Finkelstein's test may also be obtained not only in de Quervain's tenosynovitis, but also in the presence of the following conditions: inflammation of the wrist extensor tendons (intersection syndrome), and entrapment of the superficial dorsal radial sensory nerve (Wartenberg's syndrome). Neurologic testing including reflexes: biceps, triceps and brachioradialis; sharp/dull, light touch, two-point, or vibratory sensory testing; strength testing by resisted movement and grip strength dynamometer, if available. Circulatory evaluation of radial and ulnar arterial sufficiency. 1.2.3 Diagnostic imaging 1.2.3.1 Plain films of the forearm, wrist or hand may be done after taking a medical history, performing a physical examination, and determining that this study is medically relevant. [4] 1.2.3.2 CT, MRI, isotope, or similar scans of the wrist are not warranted unless there is a specific, suspected, clinical entity appropriate for the study. The examiner requesting this study should plainly state the reason for requesting the study and the treatment plan related to the results. [4] 1.2.4 Laboratory Testing a. Tendinitis/tenosynovitis or wrist pain: Certain blood tests can be useful in establishing the diagnosis of an underlying metabolic or rheumatologic disease if such a condition is suspected on the basis of the history and physical examination during the evaluation of probable tendinitis/tenosynovitis or wrist pain. [4] b. Nerve entrapment syndromes: During the evaluation of probable, entrapment syndromes, laboratory tests should be done if a contributing systemic diagnosis such as joint disease, diabetes mellitus, or thyroid disease is suspected. [4] 1.2.5 Diagnostic Injections Diagnostic injection of local anesthetic by the experienced, may be useful for diagnosis in the case of atypical presentations such as referred pain or the presence of multiple disorder. [3] 1.2.6 Electromyography and Nerve Conduction Tests. Nerve entrapment syndromes: The initial history and physical exam are the most important assessment tools and the working diagnosis may be made without confirmation by nerve conduction studies. [4] 1.3 Inappropriate initial assessment methods 1.3.1 Thermography [1] 1.3.2 Vibrometry [1] 1.3.3 Portable neurometer [1] 1.3.4 Electrodiagnostic testing to establish the diagnosis of de Quervain's tenosynovitis [1] 2.0 Initial Treatment 2.1 Purpose The purpose of initial treatment is to promote healing, optimize function and allow continued productive employment with appropriate modifications, as indicated, to avoid adverse effects. The initial treatment of nerve entrapment syndromes, tendinitis, tenosynovitis, and wrist pain is nonsurgical. Application of the conservative therapy described below will result in significant improvement in a majority of cases. Effective workplace intervention may be crucial. The period of initial (conservative) treatment should be 4 weeks with re-evaluation at least every two weeks to ascertain improvement. 2.2 Appropriate initial treatment methods 2.2.1 Education a. All injured workers with these conditions should receive instruction concerning the anatomy and nature of their condition, risk factors, preventive measures, appropriate exercises and goals of the initial treatment methods including time frame for expected improvement. [4] The responsibilities of the injured worker in implementing the treatment plan should be emphasized. Education should be provided by the treating physician and may be supplemented by a physical or occupational therapist in the context of referral for the instruction on gentle flexibility and range of motion exercises, joint protection, work simulation and conditioning. Educational literature, if provided, should be reviewed with the injured worker. Home hobby, craft, sport and avocational activities should be curtailed, as appropriate, if they are considered to be potentially aggravating or causative factors. 2.2.2 Activity and Environmental Modifications a. If occupational factors cause or aggravate the condition, appropriate work restrictions and/or ergonomic workplace changes may be advised by the provider. These should protect the involved tissues while allowing the injured worker to perform some of the specific elements of the job. [4] b. Modified work is strongly encouraged since initial treatment need not require time lost from work. [4] Prescribed modified work guidelines should be as specific as possible, avoiding generic terms such as "light duty." Examples of restrictions are a reduction in daily hours, complete restriction from aggravating or high risk tasks, or specific job rotation to promote varied hand position and activities. Other examples of such modifications include work station adjustment, tool redesign, protective equipment and other engineering controls. It may be necessary to contact the company directly to discuss alternative productive work within the scope of the prescribed restrictions. 2.2.3 Immobilization/Stabilization a. Nerve entrapment syndromes: Immobilization/stabilization of the wrist in a neutral position may be used and is most effective when worn in the night. [4] The splint should prevent wrist flexion and extension without constriction. If not properly fitted, it can lead to further nerve entrapment, muscle atrophy, vascular compression, discomfort and chafing. If a pre-formed splint does not fit properly a custom-made splint may be fabricated. [4] b. Severe de Quervain's tenosynovitis: Immobilization of the wrist and thumb interphalangeal joint with a spica thumb splint or other similar device can be considered for up to 3 to 4 weeks. [4] Splinting may not be necessary in milder cases and the functional restriction on thumb and hand use imposed by spica splinting is considerable. c. Tendinitis/tenosynovitis: Immobilization with appropriate splints should also be considered in case of moderate and severe tendinitis/tenosynovitis or for short-term(up to 4 weeks) care of wrist pain. [4] d. Splints must fit properly and should be prescribed by the provider. [4] The injured worker should be instructed in proper use of the splint, including the practice of range of motion exercises throughout the day. Careful monitoring of clinical progress is necessary during splinting to avoid the complications of muscle atrophy and joint stiffening. 2.2.4 Physical Treatments a. Appropriate manual/manipulative therapies, including joint and soft tissue mobilization may by used up to a maximum of 12 treatment visits. Referral to an appropriate provider should be considered." [3] b. Various manual and/or passive modalities should not be utilized as the sole treatment. A graduated exercise program to promote strength, flexibility, and normal function should also be utilized. [3] c. Acupuncture may be prescribed up to a maximum of 12 treatments in 4 weeks. [3] 2.2.5 Passive Modalities a. Active physical treatments can be supplemented by selected passive modalities (heat, cold, ultrasound, electrical stimulation, iontophoresis, phonophoresis, aquatic therapy) at the discretion of the provider for the first 4 weeks of treatment. [4] b. Ice treatment periods should not exceed twenty minutes. Application of appropriate modalities at home may also be useful during and following the acute inflammatory phase. [3] 2.2.6 Medications 2.2.6.1 A physician may prescribe appropriate analgesic and/or anti-inflammatory medications. [4] 2.2.6.2 Local injection of steroid medication (with or without accompanying local anesthetic can be used as an initial treatment modality for cases of (1) moderate to severe inflammation or (2) stenosing tenosynovitis which affects function, after consideration of the risks of this procedure. [4] 2.2.7 Surgical Referral for Nerve Entrapment Syndromes Surgical consultation should be made in the initial treatment phase if there is: 1) thenar muscle weakness or atrophy; 2) unremitting sensory loss or paresthesia 3) significant hand dysfunction; 4) evidence of a space occupying lesion or history of acute or traumatic onset. In these instances, an EMG/nerve conduction study may be performed to confirm the diagnosis. [4] 2.3 Inappropriate Initial Treatments 2.3.1 Surgical Treatments a. Surgical treatment of de Quervain's tenosynovitis or hand and wrist tendinitis/tenosynovitis without a trial of therapy, including a work evaluation, is generally not indicated. [1] 2.3.2 Medication a. Pyridoxine / Vitamin B6 b. Oral corticosteroids 2.3.3 Tendinitis/tenosynovitis or wrist pain: Prolonged application of passive modalities (beyond 4 weeks) [1] 2.4 Case Management During the first month of evaluation and treatment, the case management decisions must be made by the treating physician(s), based on the injured worker's clinical progress. Re-evaluation of the diagnosis, treatment effectiveness and work status should be performed by the physician at least every 2 weeks. Referral to an appropriate provider during the initial phase of treatment may be indicated for patient education, pain reduction and the implementation of a graduated program of flexibility and conditioning exercises. Referral should be considered for all patients with moderate to severe symptoms, those assigned total temporary disability and those undergoing surgical treatment. The goal is to promote healing and maximize function for a gradual return to occupational and non-occupational activities. Referral to a surgeon competent in the treatment of hand and wrist disorders is appropriate after failure of conservative treatment. 3.0 Secondary Assessment (Reassessment at 4 weeks) 3.1 Purpose The purpose of the secondary assessment is to identify the reason(s) for delayed recovery from wrist/hand symptoms and/or functional impairment after initial evaluation and treatment. This requires review of both the working diagnosis and differential diagnosis, as well as the contributing factors and the treatment approach. 3.2. Appropriate Secondary Assessment Methods 3.2.1. History The interval history should document the treatment measures prescribed and implemented, and the evolution of symptoms during this treatment. The previously recommended modifications of occupational and nonoccupational activities should also be reviewed. Current work status should be noted. If there has been no significant improvement, or worsening of symptoms, the history should be carefully reviewed to address other co-existing or contributing musculoskeletal pathologies and systemic illnesses as per the Initial Assessment section. 3.2.2 Physical Examination A reexamination should assess any changes in the upper extremity, especially tenderness, atrophy, range of motion, serial grip strength, and response to provocative maneuvers. Attention should be paid to any changes in the provocative and sensibility tests. If symptoms have worsened or remain unimproved, the physical exam should include an evaluation for undiagnosed proximal upper extremity and neck pathology. 3.2.3 Diagnostic Imaging 3.2.3.1 If not previously performed or unavailable, plain films of the forearm, wrist or hand may be considered after the medical history and physical examination indicate that this study is medically relevant. [4] 3.2.3.2 CT, MRI, isotope, or similar scans of the wrist are not warranted unless there is a specific, suspected, clinical entity which may be diagnosed by the study. The examiner requesting this study should justify the rationale for requesting the study and for supporting the treatment plan. [4] 3.2.4 Laboratory Studies Certain laboratory studies may be useful in establishing the diagnosis of an underlying metabolic or rheumatologic disease if such a condition is suspected. [4] 3.2.5 Diagnostic Injections Diagnostic injection of local anesthetic may be useful for diagnosis in the case of atypical presentations (e.g. referred pain, presence of multiple disorders). [3] 3.2.6 Electromyography and Nerve Conduction Tests 3.2.6.1 Wrist pain and tendinitis/tenosynovitis Electrodiagnostic studies are appropriate if neuropathy is suspected from the history and physical examination. [4] 3.2.6.2 Nerve Entrapment Syndromes: [4] Nerve conduction studies may be useful in the re-evaluation phase and should be reserved for: 1) cases of persistent or worsening symptoms and clinical signs despite a trial of conservative treatment; 2) cases where the diagnosis remains in question and the history and physical exam are suggestive of another type or location of nerve pathology. Electrophysiologic studies can be falsely negative in 10-20% of individuals with clinical CTS and false-positives in asymptomatic people do occur rarely. Therefore the results must be considered in the context of the history, physical exam and presence of occupational risk factors. A complete evaluation should include distal median and ulnar nerve sensory and motor nerve conduction studies under controlled limb temperature conditions. The laboratory standards for an abnormal test should be consistent with published values and stated in the report. Nerve conduction studies are also useful to determine the site of nerve impingement if a more proximal location is suspected, and can be helpful in the detection of a generalized polyneuropathy. 3.2.7 Ergonomic Evaluation If continued occupational exposure to exacerbating factors is contributing to delayed recovery a worksite evaluation by a specialist trained in ergonomics may be necessary. [4] 3.2.8 Psychological evaluation A psychological evaluation with justification may be appropriate in cases where little clinical improvement is noted. [3] 3.3 Inappropriate secondary assessment methods 3.3.1 Vibrometry [1] 3.3.2 Portable neurometer [1] 4.0 Secondary Treatment 4.1 Purpose 4.1.1 Nerve entrapment syndromes: The goal of secondary treatment is the symptom-free return to full employment (in a graded manner) with the provision of appropriate immediate and long-term work and activity modifications to prevent recurrence. Continuance of conservative treatment is warranted if symptoms are improving. If there has been no improvement, or clinical progression despite the injured worker's compliance with the initial treatment protocol (including adherence to work restrictions) further treatment strategies are recommended. These should also be considered in the injured worker who has initial improvement but plateaus with persistent symptoms during the continuation of conservative care. If there has been documented consistent improvement of symptoms and physical findings with adherence to the Initial Treatment Protocol outlined above, continued conservative treatment is warranted for up to 2-4 more months (for a total of approximately 6 months), with re-evaluation every 2-4 weeks. If there has been documented, consistent improvement of symptoms and physical findings with adherence to the Initial Treatment Protocol outlined above, continued conservative treatment is warranted. 4.1.2 Hand and wrist tendinitis/tenosynovitis: The purpose of secondary treatment of hand and wrist tendinitis/tenosynovitis is to optimize recovery from persistent symptoms. Most cases will respond to continued nonsurgical therapy. Secondary treatment for wrist pain will be diagnosis specific and designed to optimize recovery from persistent wrist pain causing conditions. 4.2 Appropriate secondary treatment methods 4.2.1 Education As part of the continuing medical and physical treatment programs, all patients should receive instruction reviewing their clinical progress, time frame for expected improvements, risk factor, preventive measures, appropriate exercises and treatment options. [4] Such instruction should be provided by the treating physician and may be supplemented by a physical or occupational therapist as part of an appropriate referral for flexibility and strengthening training. 4.2.2 Activity and environmental modifications 4.2.2.1 Restriction of occupational and nonoccupational activities which stress the affected area (via direct pressure, forceful or repetitive motion or static tension) should be continued or gradually relaxed based upon the clinical status. [4] Prescribed modified work guidelines should be as specific as possible, avoiding generic terms such as "light duty." Further direct communication with the employer can facilitate the permanent implementation of job task, tool, and workstation modifications to speed recovery and prevent recurrence. 4.2.3 Immobilization a. de Quervain's: Immobilization/stabilization for de Quervain's tenosynovitis of the wrist and thumb joint with a spica thumb splint or other device should usually not be continued for more than 4 weeks. [4] b. Hand and Wrist Tendinitis: Immobilization/stabilization with appropriate splints should be reduced as soon as the symptoms improve (e.g. use limited to performing exacerbating tasks), and discontinued when the symptoms are mild. [4] Continuous splinting should not exceed 4 weeks duration; intermittent or nocturnal splint use may be applied for longer periods. [4] Institution of splinting can be considered as a secondary treatment for persistent or worsening cases. [4] c. Nerve entrapment syndromes: If splinting has been on a continuous basis, it may be reduced to nighttime use only or PRN use for aggravating activities. [4] 4.2.4 Physical Treatments a. Graduated exercises as described in initial treatment may be continued during the rehabilitative process. [4] b. Manipulation/mobilization for joint dysfunction (not for nerve entrapment): After 6 treatment visits, an evaluation should be made to determine subjective and objective improvement. If there is no documented subjective and objective improvement, this modality should be discontinued. [3] c. Referral to an appropriate provider for training in flexibility and strengthening exercises can be considered for tendinitis/tenosynovitis. The duration of secondary physical treatment referral should not exceed 4 to 6 weeks. [4] d. Acupuncture [3] e. Biofeedback [3] 4.2.5 Passive Modalities Use of thermal modalities in conjunction with physical treatment may be useful in the treatment of tendinitis, tenosynovitis, de Quervain's, and wrist pain. 4.2.6 Medications a. Tendinitis/tenosynovitis/wrist pain: Oral nonsteroidal antiinflammatory medications (NSAIDs) may be continued judiciously after consideration of their cumulative adverse effects risk. Opioids should be reserved for pain refractory to other medications. [4] b. Nerve entrapment syndromes: If anti-inflammatory agents have been used continuously in the initial 6-8 weeks of treatment, they should be discontinued as the risk of side-effects outweighs potential benefits. [4] They may be re-instituted for brief trials in the event of symptom flare. Acetaminophen may be used periodically. [4] 4.2.7 Injection 4.2.7.1 Tendinitis/Tenosynovitis a. If not used during the first month, local injection of steroid medication (with or without accompanying local anesthetic medication)can be used for cases of persistent symptoms after consideration of the risks of this procedure. [4] b. Repeat corticosteroid injections can be given at intervals, to a maximum of 3 injections during the course of the second and third months. [4] c. The suspected presence of focal infection (e.g. tuberculous tendinitis) is a contraindication to steroid injection. Extra caution is warranted in the injection of steroids around the extensor pollicis longus tendon at or distal to Lister's tubercle given the elevated risk of tendon rupture. [4] d. Steroid injection therapy must be accompanied by the activity modifications discussed above. 4.2.7.2 Nerve Entrapment Nerve Entrapment corticosteroid injection (with or without local anaesthetic) can be considered if significant symptoms (especially paresthesias) persist. [4] Injections are only occasionally curative, usually in the injured worker who has been symptomatic for less than three months. A significant percentage of people have attenuation of their symptoms with injection, a good prognostic sign if surgery is eventually necessary. Symptoms frequently return within weeks to months. If there is improvement in symptoms, the injection serves as a diagnostic aid. If relief is prolonged (weeks to months), repeat injections can be given, to a maximum of three, at intervals not less than 6-8 weeks apart. Contraindications - drug allergy, bleeding disorder, space-occupying lesion. Potential complications - local hematoma, infection, tendon rupture, reflex sympathetic dystrophy, and inadvertent injection of the median nerve with worsening symptoms. Transient median nerve symptoms occur frequently. 4.2.8 Surgical Treatments 4.2.8.1 Tendinitis/Tenosynovitis a. Surgical intervention can be considered for cases showing little or no improvement after failure of conservative therapy. [4] b. Many cases of refractory tendinitis/tenosynovitis are due to the presence of conditions which are not amenable to nonsurgical treatment (e.g. anomalous tendon slips, strictures, large calcifications, tendon subluxation. [4] 4.2.8.2 Nerve entrapment syndromes: Surgical consultation in the re-assessment phase is indicated if: [4] a. the diagnosis of Nerve Entrapment Syndromes has been reasonably established and other pathologies excluded; and b. atrophy or weakness is present; or c. there is unremitting sensory loss or paresthesias or markedly abnormal nerve conduction studies; or d. the injured worker has failed a 3-6 month course of adequate conservative therapy; or e. the symptoms and physical signs continue to progress during conservative therapy. Surgery should be performed only by a Hand, Orthopedic, Plastic, or Neuro Surgeon with extensive experience in the selection of candidates for surgical intervention and in the procedure itself. Surgical aftercare should be managed by the surgeon. 4.2.8.3 Surgical procedures are indicated for an appropriately diagnosed, surgically correctable lesions. 4.3 Inappropriate Secondary Treatment Methods 4.3.1 Medications a. Use of oral corticosteroids is rarely indicated. [1] b. Pyridoxine / Vitamin B6 [1] c. Muscle relaxants [1] 4.4 Case management If the injured worker has not resumed near normal work duties after 8 weeks of full conservative therapy including adherence to a graded exercise program, a referral to a physician trained and experienced in the evaluation and treatment of occupational disorders or an orthopedic surgeon is recommended. Consultation should include a complete evaluation and recommendations for treatment and return to appropriate work. If psychosocial issues are judged to contribute to delayed recovery or heightened disability, it may be appropriate to have a psychiatric evaluation. If the condition becomes chronic or disabling despite full conservative treatment including appropriate medical, rehabilitative, and ergonomic interventions (and surgery if indicated), the injured worker should be evaluated for permanent disability. 5.0 Primary References 1.

The Request for Qualified Medical Evaluator Panel Selection Instruction Form. STATE OF CALIFORNIA GRAY DAVIS, GOVERNOR ---------------------------------------------------------------- DEPARTMENT OF INDUSTRIAL RELATIONS INDUSTRIAL MEDICAL COUNCIL ADDRESS REPLY TO: 395 OYSTER POINT BLVD., STE. 102 P.O. Box 8888 SOUTH SAN FRANCISCO, CA 94080 San Francisco, CA 94128-8888 TEL: (650) 737-2700 (800) 794-6900 Fax: (650) 737-2911 To: Injured Worker This list of Qualified Medical Evaluator (QME) physicians is being issued to you because a "Request for a Qualified Medical Evaluator" form was received in our office. These physicians were randomly selected by a computer. The QME you choose will evaluate or make determinations on medical questions about your work injury. For injuries prior to 1/1/94, the QME performs the final permanent disability evaluation once your treating physician determines that you condition is permanent and stationary. For injuries as of 1/1/94, a QME is only used when there is a dispute over the primary treating physicians report. Please take the following steps: 1) Select one QME physician off the list Your claims administrator (or if none, employer) should not select the QME or influence you on which physician to pick. You may consult with an Information and Assistance Officer in your area by calling 1-800-736-7401 before making a selection. You may also consult with an attorney. If you decide to become represented by an attorney, you should not select a QME from the list. For injuries on or after 1/1/94, if your primary treating physician or an other physician(s) who has treated you for this injury is listed on your panel you must call the Industrial Medical Council (IMC) for a replacement since your primary treating physician(s) cannot also be your QME. 2) Call the QME physician's office to make your appointment. Make it clear to the QME's office staff that you are calling for a "QME exam". The person at the doctor's office will ask you for information that you will find on the upper right corner of the attached form. If the doctor you choose from your panel cannot arrange an appointment for evaluation with you within 60 days of your call, the QME's office may not offer you a substitute QME who is not on the list. You may: a) select one of the other QMEs on the list; b) call the IMC at 1-800-794-6900 to request that the unavailable QME on the list be replaced; or c) agree to wait over the 60-day period to see any of the QMEs listed on your panel. 3) Review of medical records You should be provided with copies of medical and non-medical records at least 20 days before information is to be provided to the QME. Within 10 days of receipt of the records, you may object to any non-medical records that might be sent to the QME for review. If you plan to provide information to the QME, you must provide a copy of any medical or non-medical records you will be providing the QME to the claims administrator (or employer) at least 20 days before information is to be provided to the QME. Failure to send a copy of all records being sent to the QME may adversely affect your claim. Your claims administrator (or employer) has 10 days after receiving the information to object to non-medical records. Copies of non-medical records objected to will not be provided to the QME but may be seen by the workers' compensation judge in your case, or by the QME at a later date if your claims administrator contests medical issues in your claim. 4) Your employer will pay for the exam Your claims administrator (or employer) will pay for the exam, any translator services you need for the exam and for any reasonable cost to get you to and from the QME evaluation. You will also be paid disability benefits for each day of the evaluation, if you lose wages. 5) If the IMC does not provide you with a panel of QMEs within 15 working days of receipt of your request, you may choose any QME (with the proper specialty for your injury). If the difference between "Date Request Received" and "Date of Issue" on your panel shows more than 15 working days, you may: choose to go to one of the QMEs on your panel; go to any Information and Assistance Office for assistance in choosing a QME; or call the Industrial Medical Council at 1-800-794-6900 to request a new panel of QMEs with the specialty you need for your evaluation. 6) A QME may not offer or solicit you to become your treating physician. However, you have the right to request the QME to become your treating physician. You may wish to consult with an Information and Assistance officer prior to this decision. 7) For additional information contact the IMC and request its pamphlets "Your Medical Evaluation" and "Fact Sheet for Injured Workers". 8) If the QME does not send the report on time, contact the IMC. (a) 30 days of your appointment - if date of injury is on or after 1/1/94 or, (b) 45 days of your appointment - if date of injury is between 1/1/91 and 12/31/93.

Such notice shall direct the physician to file a copy of his or her advertising with the Medical Director within 15 working days of the date on which the notice was served. (b) The Medical Director may take such steps as he or she deems necessary to determine whether the complaint has merit. (1) The Medical Director shall respond to the complaint within 15 working days of the Council's receipt of the physician's response and notify the complainant that the Council: (A) will investigate the complaint; or (B) will require additional time to ascertain whether the complaint has merit; or (C) will refer a copy of the complaint to another agency which also has jurisdiction over the subject matter of the complaint; or (D) will take no further action on the complaint because the Council lacks jurisdiction over the person or conduct complained of; or (E) will take no further action on the complaint because the allegations of the complaint do not warrant further action by the Council for the reasons stated in the response. (c) At the time of filing the advertising copy with the Medical Director, the physician shall also file an answer to the complaint, briefly setting forth the grounds on which the physician believes the copy to be in compliance with Business and Professions Code Section 651, and the provisions of these regulations.

Upon reviewing the physician's answer, the Medical Director may dismiss or informally resolve the complaint where he or she deems such action appropriate. (d) The Council may, without receipt of a complaint, request a physician to provide a copy of any advertising used by that physician for review. Such a request shall be made in writing, and shall be personally served on the physician. (e) If a physician who has been appointed as a QME fails to deliver a copy of the advertising used to the Council within 15 working days of receipt of the notice, the Council may infer from the failure to comply that the advertising material used by the QME is in violation of Business and Professions Code Section 651, or these regulations. The maximum penalty that the Council may impose for a finding of violation based solely on the negative inference created by this provision shall be suspension of the physician's appointment as a Qualified Medical Evaluator for a period of six months followed by a period of probation not to exceed one year. (f) If a non-QME physician fails to deliver a copy of the advertising used to the Council within 15 working days of receipt of the request, the Council shall refer the matter to that physician's licensing board for such proceedings as that board may deem proper.

(a) If, after reviewing the physician's advertising copy and the physician's answer to the complaint, the Medical Director determines that the advertising copy violates Business and Professions Code Section 651, or these regulations, he or she shall submit a preliminary determination to the Council. (b) If the Council sustains the Medical Director's preliminary determination, and the physician subject to the complaint is not a QME, the Medical Director shall forward a copy of the preliminary determination, the complaint, and all supporting documentation to the appropriate physician's licensing board for such proceedings as that board may deem proper. (c) If the Council sustains the Medical Director's preliminary determination, and the physician subject to the complaint is a QME, the Council shall hold a hearing on the complaint in accordance with Chapter 4 (commencing with Sections 11370) of Part 1 of Division 3 of the Government Code. (1) The Council may delegate in whole or in part to the Administrative Law Judge the authority to conduct the hearing and decide upon the complaint. (2) Upon a decision being made regarding the complaint, the Administrative Law Judge, acting alone, or as advisor to the Council, shall file a copy of the written statement of findings and decision with the Council. (d) Within 30 days of the date the written decision is served upon the QME, the QME may file a written notice of appeal with the Council requesting reconsideration by the Council of the Administrative Law Judge's decision. Upon receipt of the notice of appeal, the Chairperson of the Council shall appoint 3 Council members to serve as an appellate panel to hear and recommend to the Council, a decision on the appeal. (1) The appeal panel shall review the entire record and may hold a hearing thereon. (2) In the event of a hearing, the designated chair of the appeal panel shall fix the time and place of the hearing and notify the parties to the appeal in writing not less than 15 working days in advance of the hearing in accordance with Code of Civil Procedure Sections 1013a and 2015.5. (3) The hearing on the appeal shall be limited to a review of the record before the Administrative Law Judge and such written and/or oral argument as the parties may submit. (4) Upon reaching a decision on the appeal, the appeal panel shall submit to the Council a copy of the record and a written report summarizing the evidence, findings of fact, and a recommended decision.

The notice shall identify the violation and the action needed to correct the violation. The notice shall state that the program will be deregistered unless corrective action is completed within thirty days. Upon a showing of good cause, the Chief may grant the sponsor a reasonable extension of time to achieve corrective action. Where the Chief has information that a program has had no active apprentices for a period of two (2) years, that shall be considered grounds for deregistration and the Chief shall notify the program sponsor in writing as set forth above that the program will be deregistered unless the program can show good cause within thirty (30) days why it should not be deregistered; (2) The Chief shall advise the sponsor in every reasonable way to help the program sponsor correct the violation; (3) If the required correction is made, the Chief may periodically review the program to see that the correction is maintained; (4) If the required correction is not completed, or if a program which has had no active apprentices for a period of two (2) years fails to show good cause why it should not be deregistered, within the allotted time, the Chief shall send a notice to the sponsor, by registered or certified mail, return receipt requested. The notice shall: (A) State that it is sent pursuant to this subsection; (B) Indicate that the program has had no active apprentices for a period of two (2) years and has failed to show good cause why it should not be deregistered; or identify the violation with particularity, state when it was called to the sponsor's attention, identify the correction required and state that the sponsor has failed or refused to correct the violation; (C) State that the Chief will recommend that the Administrator deregister the program unless the sponsor requests a hearing within fifteen days of the date of the notice; (5) If the sponsor does not request a hearing, the Chief shall transmit to the Administrator a report containing all pertinent facts and circumstances concerning the violation, including the findings and recommendation for deregistration, and copies of all relevant documents and records.

At the Administrator's discretion, he/she may allow the sponsor a reasonable period of time to achieve corrective action. (7) The decision of the Administrator concerning deregistration of a program shall be final and become an order of the Council unless an appeal is filed by the sponsor with the Council within thirty (30) days following the date the decision is issued. If the program is deregistered, and no appeal to the Council is filed, the deregistration shall be effective sixty (60) days following the date the Administrator's Decision was issued. (8) The sponsor may appeal the Administrator's Decision to the Council. If an appeal is filed, the procedures of Section 203 shall be followed. The Decision of the Council shall be final and shall be effective thirty (30) days following the date the Council's Decision is issued. (9) Upon issuance of the Administrator's Decision to deregister, the Administrator shall make public notice of this Decision and shall notify the sponsor and other programs in the same occupation and in the same labor market area. Within 15 days of service of the Administrator's Decision, the sponsor shall notify each apprentice of the Administrator's Decision to deregister the program. The sponsor shall inform each apprentice that, if the deregistration decision becomes final, it automatically terminates the apprentice's individual registration.

(a) Contractors shall provide contract award information to the apprenticeship committee for each applicable apprenticeable craft or trade in the area of the site of the public works project that has approved the contractor to train apprentices. Contractors who are not already approved to train by an apprenticeship program sponsor shall provide contract award information to all of the applicable apprenticeship committees whose geographic area of operation includes the area of the public works project.

Unless an exemption has been granted, the contractor shall employ apprentices for the number of hours computed above before the end of the contract. Contractors who are not already approved to train by an applicable joint apprenticeship committee or unilateral committee must request the dispatch of required apprentices from one of the applicable Apprenticeship Committees whose geographic area of operation includes the site of the public work by giving the committee actual notice of at least 48 hours (excluding Saturdays, Sundays and holidays) before the date on which one or more apprentices are required. However, if a non-signatory contractor declines to abide by and comply with the terms of a local committee's standards, the Apprenticeship Committee shall not be required to dispatch apprentices to such contractor. Conversely, if in response to a written request an Apprenticeship Committee does not dispatch any apprentice to a contractor who has agreed to employ and train apprentices in accordance with either the Apprenticeship Committee's Standards or these regulations within 72 hours of such request (excluding Saturdays, Sundays and holidays) the contractor shall not be considered in violation of this section as a result of failure to employ apprentices for the remainder of the project, provided that the contractor made the request in enough time to meet the above-stated ratio. If an Apprenticeship Committee dispatches fewer apprentices than the contractor requested, the contractor shall be considered in compliance if the contractor employs those apprentices who are dispatched, provided that, where there is more than one Apprenticeship Committee able and willing to unconditionally dispatch apprentices, a contractor who is not a participant in an apprenticeship program has requested dispatch from at least two committees. (b) Apprentices employed on public works shall be paid the applicable apprentice prevailing per diem wage rate, available from DAS, and derived from the Director's survey of wages paid on public works in the geographic area of the craft or trade. DAS shall refer complaints alleging any contractor's failure to pay the proper apprentice prevailing wage rate on a public works project to the Division of Labor Standards Enforcement for investigation and appropriate action. (c) Apprentices employed on public works can only be assigned to perform work of the craft or trade to which the apprentice is registered. Work of the craft or trade consists of job duties normally assigned to journeymen in the apprenticeable occupation. Where an employer employs apprentices under the rules and regulations of the California Apprenticeship Council, as set forth in Labor Code Section 1777.5(c)(2), apprentices employed on public works must at all times work with or under the direct supervision of journeyman/men. The on-the-job training shall be in accordance with the apprenticeship standards and apprenticeship agreement under which the apprentice is training, provided that a contractor shall not be subject to any financial or administrative obligations to a trust fund or employee benefit plan unless the contractor has so agreed. (d) Contractors who have bid or have been awarded public works projects prior to January 1, 2000 and contractors who have bid prior to January 1, 2000 and have been awarded public works projects after January 1, 2000 shall comply with the provisions of Labor Code Section 1777.5 in effect prior to January 1, 2000, as implemented by California Apprenticeship Council regulations in effect prior to January 1, 2000.

Only apprenticeship programs that have had approval under Labor Code section 3075 for the entire fiscal year and are in existence at the time of the distribution of funds shall be entitled to receive a share of the distributed contributions. Contributions shall be distributed as follows: (i) payment shall first be made to the Division of Apprenticeship Standards for its budgeted expenses to administer this subdivision in the fiscal year in which the distribution is made; (ii) where there is only one applicable apprenticeship program in the same occupation for which contributions were made whose geographic area of operation as defined in 8 C.C.R. section 205(n) includes the county in which the work was performed, those contributions will be distributed to that program less the pro rata share of expenses paid by DAS; and (iii) where there are two or more applicable apprenticeship programs in the same occupation for which contributions were made whose geographic area of operation as defined in 8 C.C.R. section 205(n) includes the county in which the work was performed, those contributions will be distributed to each such program in proportion to the total number of registered apprentices that DAS has recorded in that program on June 30 of the fiscal year for which contributions were received less the pro rata share of expenses paid by DAS. "Pro rata share of expenses" means the share of DAS expenses that bears the same ratio to the contributions to be distributed as the total DAS expenses bear to the total contributions received in the fiscal year.

The certified mail requirement shall end after two years from the notice of the determination. (h) For purposes of Labor Code Section 1777.7, a contractor knowingly violates Labor Code Section 1777.5 if the contractor knew or should have known of the requirements of that Section and fails to comply, unless the failure to comply was due to circumstances beyond the contractor's control. There is an irrebuttable presumption that a contractor knew or should have known of the requirements of Section 1777.5 if the contractor had previously been found to have violated that Section, or the contract and/or bid documents notified the contractor of the obligation to comply with Labor Code provisions applicable to public works projects, or the contractor had previously employed apprentices on a public works project.

(a) Within ten (10) days following its receipt of a Request for Review, the Chief DAS shall also notify the Affected Contractor, Subcontractor, or Responsible Officer, if applicable, of its opportunity and the procedures for reviewing evidence to be utilized by the Chief DAS at the hearing on the Request for Review. (b) The Chief DAS shall be deemed to have provided the opportunity to review evidence required by this Rule if it (1) gives the Affected Contractor, Subcontractor, or Responsible Officer the option, at the Affected Contractor's, Subcontractor's, or Responsible Officer's own expense, to either (A) obtain copies of all such evidence through a commercial copying service or (B) inspect and copy such evidence at the office of the Chief DAS during normal business hours; or if (2) the Chief DAS at its own expense forwards copies of all such evidence to the Affected Contractor, Subcontractor, or Responsible Officer. (c) The evidence required to be provided under this Rule shall include the identity of witnesses whose testimony the Chief DAS intends to present, either in person at the hearing or by declaration or affidavit. This provision shall not be construed as requiring the Chief DAS to prepare or provide any separate listing of witnesses whose identities are disclosed within the written materials made available under subpart (a). (d) The Chief DAS shall make evidence available for review as specified in subparts (a) through (c) within 20 days of its receipt of the Request for Review; provided that, this deadline may be extended by written request or agreement of the Affected Contractor, Subcontractor, or Responsible Officer. The Chief DAS's failure to make evidence available for review as required by Labor Code section 1777.7(c) and this Rule, shall preclude the Chief DAS from introducing such evidence in proceedings before the Hearing Officer or the Administrator. (e) This Rule shall not preclude the Chief DAS from relying upon or presenting any evidence first obtained after the initial disclosure of evidence under subparts (a) through (d), provided that, such evidence is promptly disclosed to the Affected Contractor, Subcontractor, or Responsible Officer. This Rule also shall not preclude the Chief DAS from presenting previously undisclosed evidence to rebut new or collateral claims raised by another Party in the proceeding.

(a) An Affected Contractor, Subcontractor, or Responsible Officer may withdraw a Request for Review by written notification at any time before a decision is issued or by oral motion on the hearing record. The Hearing Officer may grant such withdrawal by letter, order or decision served on the Parties. (b) For good cause, a Request for Review so dismissed may be reinstated by the Hearing Officer or the Administrator upon a showing that the withdrawal resulted from misinformation given by the Chief DAS or otherwise from fraud or coercion. A motion for reinstatement must be filed within 60 days of service of the letter, order or decision granting withdrawal of the Request for Review or, in the event of fraud which could not have been suspected or discovered with the exercise of reasonable diligence, within 60 days of discovery of such fraud. The motion shall be accompanied by a declaration containing a statement that any facts therein are based upon the personal knowledge of the declarant. (c) Notwithstanding any application or showing made under subpart (b) of this Rule, neither the Hearing Officer nor the Administrator may reinstate any Request for Review where the underlying Determination has become final and entered as a court judgment. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.26. Dismissal or Amendment of Determinations. (a) Upon motion to the appointed Hearing Officer, the Chief DAS may dismiss or amend a Determination as follows: (1) A Determination may be dismissed or amended to eliminate or reduce a charge of violation from serious and knowing to knowing, an amount of monetary penalty, or a period of debarment that is not warranted under the facts and circumstances of the case, or that has been satisfied, or to conform to an order of the Hearing Officer or the Administrator. (2) For good cause, a Determination may be amended to revise or increase a charge from knowing to serious and knowing, an amount of monetary penalty, or a period of debarment based upon a recomputation or the discovery of new evidence subsequent to the issuance of the original Assessment or Notice. (b) The Hearing Officer shall grant any motion to dismiss or amend a Determination downward under subparts (a)(1) absent a showing that such dismissal or amendment will result in the forfeiture of substantial substantive rights of another Party to the proceeding. The Hearing Officer may grant a motion to amend a Determination upward under subpart (a)(2) under such terms as are just, including where appropriate the extension of an additional opportunity for early settlement under Rule 21 [Section 232.21]. Unless the Hearing Officer determines otherwise, an amended Determination shall be deemed fully controverted without need for filing an additional or amended Request for Review. (c) The Administrator may, upon the record on review of the Determination and without amendment, increase or decrease the penalty - whether civil penalty or debarment - based upon consideration of the factors listed in Labor Code section 1777.7(f). Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.27. Early Disposition of Untimely Assessment, Withholding, or Request for Review. (a) Upon the application of any Party or upon his or her own motion, the appointed Hearing Officer may issue an Order to Show Cause why a Determination or a Request for Review should not be dismissed as untimely under the relevant statute. (b) An Order to Show Cause issued under subpart (a) of this Rule shall be served on all Parties who have appeared or been served with any prior notice in the matter and shall provide the Parties with at least 10 days to respond in writing to the Order to Show Cause and an additional 5 days following the service of such responses to reply to any submission by any other Party. Evidence submitted in support or opposition to an Order to Show Cause shall be by affidavit or declaration under penalty of perjury. There shall be no oral hearing on an Order to Show Cause issued under this Rule unless requested by a Party or by the Hearing Officer. (c) After the time for submitting responses and replies to the Order to Show Cause has passed or after the oral hearing, if any, the Hearing Officer may do one of the following: (1) recommend that the Administrator issue a decision setting aside the Determination or dismissing the Request for Review as untimely under the statute; (2) find the Determination or Request for Review timely and direct that the matter proceed to hearing on the merits; or (3) reserve the timeliness issue for further consideration and determination in connection with the hearing on the merits. (d) A decision by the Administrator which sets aside a Determination or which dismisses a Request for Review as untimely shall be subject to reconsideration and to judicial review in the same manner as any other Final Order or Decision of the Administrator. A determination by the Hearing Officer that the Determination or Request for Review was timely or that the timeliness issue should be reserved for further consideration and determination in connection with the hearing on the merits shallnotbe subject to appeal or review except as part of any reconsideration or appeal from the Decision of the Administrator made after the hearing on the merits.

Finality of Determinations When No Timely Request for Review is Filed; Authority of Awarding Body to Disburse Withheld Funds. (a) Upon the failure of an Affected Contractor, Subcontractor or Responsible Officer to file a timely Request for Review under Labor Code section 1777.7(c) and Rule 22 [Section 232.22] above, the Determination of civil penalty or debarment shall become a "final order" as to the Affected Contractor, Subcontractor, or Responsible Officer that the Chief DAS may certify and file with the superior court in accordance with Labor Code section 1777.7(c)(6). (b) Where a Determination of civil penalty or debarment has become final as to at least one but not as to every Affected Contractor, Subcontractor, or Responsible Officer, the Awarding Body shall continue to withhold and retain the amounts required to satisfy any penalties at stake in a review proceeding initiated by any other Affected Contractor, Subcontractor, or Responsible Officer until there is a final order in that proceeding that is no longer subject to judicial review. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.29. [Reserved]. s 232.30. Scheduling of Hearing; Continuances and Tolling. (a) The appointed Hearing Officer shall establish the place and time of the hearing on the merits, giving due consideration to the needs of all Parties and the statutory time limits for hearing and deciding the matter. Parties are encouraged to communicate scheduling needs to the Hearing Officer and all other Parties at the earliest opportunity. It shall not be a violation of Rule 07 [Section 232.07]'s prohibition on ex parte communications for the Hearing Officer or his or her designee to communicate with Parties individually for purposes of clearing dates and times and proposing locations for the hearing. The Hearing Officer may also conduct a prehearing conference by telephone or any other expeditious means for purposes of establishing the time and place of the hearing. (b) Once a hearing date is set, a request for a continuance that is not joined in by all other Parties or that is for more than 30 days will not be granted absent a showing of extraordinary circumstances, giving due regard to the potential prejudice to other Parties in the case and other Persons affected by the matter under review. Absent an enforceable waiver (see subpart (d) below), no continuance will be granted nor any proceeding otherwise delayed if doing so is likely to prevent the Hearing Officer from commencing the hearing on the matter within the statutory time limit. (c) A request for a continuance that is for 30 days or less and is joined by all Parties shall be granted upon a showing of good cause. Notwithstanding subpart (b) above, a unilateral request for a continuance made by the Party who filed the Request for Review shall be granted upon a showing of good cause if the new date for commencing the hearing is no more than 120 days after the date of service of the Determination of civil penalty or debarment (d) If a Party makes or joins in any request that would delay or otherwise extend the time for hearing or deciding a review proceeding beyond any prescribed time limit, such request shall also be deemed a waiver by that Party of that time limit. (e) The time limits for hearing and deciding a review proceeding shall also be deemed tolled (1) when proceedings are suspended to seek judicial enforcement of a subpoena or other order to compel the attendance, testimony, or production of evidence by a necessary witness; (2) when the proceedings are stayed or enjoined by any court order; (3) between the time that a proceeding is dismissed and then ordered reinstated under Rule 25 [Section 232.25] above; (4) upon the order of a court reinstating or requiring rehearing of the merits of a proceeding; or (5) during the pendency of any other cause beyond the Administrator's direct control (including but not limited to natural disasters, temporary unavailability of a suitable hearing facility, or absence of budget authority) that prevents the Administrator or any appointed Hearing Officer from carrying out his or her responsibilities under these Rules. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.31. Prehearing Conference. (a) Upon the application of any Party or upon his or her own motion, the appointed Hearing Officer may conduct a prehearing conference for any purpose that may expedite or assist the preparation of the matter for hearing or the disposition of the Request for Review. The prehearing conference may be conducted by telephone or other means that is convenient to the Hearing Officer and the Parties. (b) The Hearing Officer shall provide reasonable advance notice of any prehearing conference conducted pursuant to this Rule. The Notice shall advise the Parties of the matters which the Hearing Officer intends to cover in the prehearing conference, but the failure of the Notice to enumerate some matter shall not preclude its discussion or consideration at the conference. The Notice shall advise the Parties that failure to appear at the prehearing conference may subject the Parties to default, pursuant to Rule 46 [Section 232.46]. (c) With or without a prehearing conference, the Hearing Officer may issue such procedural Orders as are appropriate for the submission of evidence or briefs and conduct of the hearing, consistent with the substantial rights of the affected Parties. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.32. Consolidation and Severance. (a) The Hearing Officer may consolidate for hearing and decision any number of proceedings where the facts and circumstances are similar and consolidation will result in conservation of time and expense. Where the Hearing Officer proposes to consolidate proceedings on his or her own motion, the Parties shall be given reasonable notice and an opportunity to object before consolidation is ordered. (b) The Hearing Officer may sever consolidated proceedings for good cause. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.33. Prehearing Motions; Cut Off Date. (a) Any motion made in advance of the hearing on the merits, any opposition thereto, and any further reply shall be in writing and directed to the appointed Hearing Officer. No particular format shall be required; however, the following information shall appear prominently on the first page: (1) the case name (i.e., names of the Parties); (2) any assigned case number; (3) the name of the Hearing Officer to whom the paper is being submitted; (4) the identity of the Party submitting the paper; (5) the nature of the relief sought; and (6) the scheduled date, if any, for the hearing on the merits of the Request for Review. The motion shall also include a Proof of Service, as defined in Rule 10 [Section 232.10] above, showing that copies have been served on all other Parties to the proceeding. (b) Prehearing motions shall be served and filed no later than 20 days prior to the hearing on the merits of the Request for Review. Any opposition shall be served and filed no later than 10 days after service of the motion or at least 7 days prior to the hearing on the merits, whichever is earlier. The Hearing Officer may in his or her discretion decide the motion in writing in advance of the hearing on the merits or reserve the matter for further consideration and determination at the hearing on the merits. (c) There shall be no right to a separate oral hearing on any prehearing motion, except in those instances in which an oral hearing has been specially requested by a Party or the Hearing Officerandin which the enforcement or forfeiture of a fundamental right is at stake. When the Hearing Officer determines that such an oral hearing is necessary or appropriate, it may be conducted by telephone or other manner that is convenient to the Parties. (d) With the exception of timeliness challenges under Rule 27 [Section 232.27], prehearing motions which seek to dispose of a Request for Review or any related claim or defense are disfavored and ordinarily will not be considered prior to the hearing on the merits. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.34. Evidence by Affidavit or Declaration. (a) At any time 20 or more days prior to commencement of a hearing, a Party may serve upon all other Parties a copy of any affidavit or declaration which the proponent proposes to introduce in evidence, together with a notice as provided in subpart (b). Unless another Party, within 10 days after service of such notice, delivers to the proponent a request to cross-examine the affiant or declarant, the right to cross-examine such affiant or declarant is waived and the affidavit or declaration, if introduced in evidence, shall be given the same effect as if the affiant or declarant had testified in person. If an opportunity to cross-examine an affiant or declarant is not afforded after request therefor is made as herein provided, the affidavit or declaration may be introduced in evidence, but shall be given only the same effect as other hearsay evidence. (b) The notice referred to in subpart (a) shall be substantially in the following form with the appropriate information inserted in the places enclosed by brackets: "The accompanying affidavit or declaration of [name of affiant or declarant] will be introduced as evidence at the hearing in [title and other information identifying the proceeding]. [Name of affiant or declarant] will not be called to testify orally, and you will not be entitled to question the affiant or declarant unless you notify [name of the proponent, Representative, agent or attorney] at [address] that you wish to cross-examine the affiant or declarant. Your request must be mailed or delivered to [name of proponent, Representative, agent or attorney] on or before [specify date atleast10 days after anticipated date of service of this notice on the other Parties]." (c) If a timely request is made to cross-examine an affiant or declarant under this Rule, the burden of producing that witness at the hearing shall be upon the proponent of the witness. If the proponent fails to produce the witness, the affidavit or declaration may be introduced in evidence, but shall be given only the same effect as other hearsay evidence under Rule 232.44.

(a) Subpoenas and subpoenas duces tecum may be issued for attendance at a hearing and for the production of documents at any reasonable time and place or at a hearing. (b) Subpoenas and subpoenas duces tecum shall be issued by the Hearing Officer at the request of a Party, or by the attorney of record for a Party, in accordance with sections 1985 to 1985.6, inclusive, of the Code of Civil Procedure. The burden of serving a subpoena that has been issued by the Hearing Officer shall be upon the Party who requested the subpoena. (c) Service of subpoenas and subpoenas duces tecum, objections thereto, and mileage and witness fees shall be governed by the provisions of Government Code sections 11450.20 through 11450.40. (d) Subpoenas and subpoenas duces tecum shall be enforceable through the Contempt and Monetary Sanctions provision set forth in Rule 47 [Section 232.47] below. A Party aggrieved by the failure or refusal of any witness to obey a subpoena or subpoena duces tecum shall have the burden of showing to the satisfaction of the Hearing Officer that the subpoena or subpoena duces tecum was properly issued and served and that the testimony or evidence sought was necessary to prove or disprove a significant claim or defense in the proceeding.

Written Notice to Party in Lieu of Subpoena. (a) In the case of the production of a Party of record in the proceeding or of a Person for whose benefit a proceeding is prosecuted or defended, the service of a subpoena upon any such witness is not required if written notice requesting the witness to attend, with the time and place of the hearing, is served on the attorney of the Party or Person. For purposes of this Rule, a Party of record in the proceeding or Person for whose benefit a proceeding is prosecuted or defended includes an officer, director, or managing agent of any such Party or Person. (b) Service of written notice to attend under this Rule shall be made in the same manner and subject to the same conditions provided in section 1987 of the Code of Civil Procedure for service of written notice to attend in a civil action or proceeding. (c) The Hearing Officer shall have authority under Rule 47 [Section 232.47] below to sanction a Party who fails or refuses to comply with a written notice to attend that meets the requirements of this Rule and has been timely served in accordance with section 1987 of the Code of Civil Procedure. However, the Hearing Officer may not initiate contempt proceedings against the witness for failing to appear based solely on non-compliance with a written notice to attend served on the Party's attorney. A Party seeking sanctions for another Party's failure or refusal to comply with a written notice to attend shall have the burden of showing to the satisfaction of the Hearing Officer that the written notice to attend was properly issued and timely served and that the testimony or evidence sought was necessary to prove or disprove a significant claim or defense in the proceeding.

(a) There shall be no right to take oral depositions or obtain any other form of discovery that is not expressly authorized under these Rules. (b) Oral depositions may be conducted only by stipulation of all Parties to the proceedings or by order of the appointed Hearing Officer upon a showing of substantial good cause.

Notice of Appointment of Hearing Officer; Objections. (a) Notice of the Appointment of a Hearing Officer under Rule 04 [Section 232.04] above shall be provided to the Parties as soon as practicable and no later than when the matter is noticed for a prehearing conference or hearing. (b) The Administrator or Chief Counsel under Rule 04 [Section 232.04] may appoint a different Hearing Officer to conduct and hear the review or to conduct and dispose of any preliminary or procedural matter in a given case.

The motion shall be filed with the Chief Counsel of the Office of the Director at the address indicated in Rule 23 [Section 232.23] above. Notwithstanding the foregoing time limits, if a Party subsequently discovers facts constituting grounds for the disqualification of the Hearing Officer, including but not limited to that the Hearing Officer has received a prohibited ex parte communication in the pending case, the motion shall be filed as soon as practicable after the facts constituting grounds for disqualification are discovered. (d) Upon receipt of a motion to disqualify the Hearing Officer, the Administrator may: (1) consider and decide the motion or appoint another Hearing Officer to consider and decide the motion, in which case the challenged Hearing Officer shall first be given an opportunity to respond to the motion, but no proceedings shall be conducted by the challenged Hearing Officer until the motion is determined; or (2) appoint another Hearing Officer to hear the Request for Review, in which case the motion shall be deemed moot.

Time and Place of Hearing. (a) A hearing on the merits of a timely Request for Review shall be commenced within 90 days after the date it is received by the office of the Administrator. The hearing shall be conducted at a suitable location within the county where the appointed Hearing Officer maintains his or her regular office, unless the hearing is moved to a different county in accordance with subpart (b) below. (b) Upon the agreement of the Parties or upon a showing of good cause by either the Party who filed the Request for Review or the Chief DAS, the hearing shall be conducted at a suitable location within either (1) the county where a majority of the subject public works employment was performed, or (2) any other county that is proximate to or convenient for the Parties and necessary witnesses. (c) A suitable location under this section means one that is open and accessible to members of the public and which includes appropriate facilities for the recording of testimony. Any facility that is regularly used by any state agency or by the Awarding Body for public hearings and that will reasonably accommodate the anticipated number of Parties and witnesses involved in the proceeding, is presumed suitable in the absence of a contrary showing. Parties seeking to change the location of a hearing under subpart (b) shall make reasonable efforts to identify, agree upon, and arrange for the availability of a suitable location within a county specified in subpart (b)(1) or (b)(2).

(b) Notwithstanding the provisions of subpart (a), the Hearing Officer may order closure of a hearing or make other protective orders to the extent necessary to: (1) preserve the confidentiality of information that is privileged, confidential, or otherwise protected by law; (2) ensure a fair hearing in the circumstances of the particular case; or (3) protect a minor witness or a witness with a developmental disability from intimidation or other harm, taking into account the rights of all persons. (c) Upon motion of any Party or upon his or her own motion, the Hearing Officer may exclude from the hearing room any witnesses not at the time under examination.

(b) Every Party shall have the right to call and examine witnesses; to introduce exhibits; to question opposing witnesses on any matter relevant to the issues even though that matter was not covered in the direct examination; to impeach any witness regardless of which Party first called the witness to testify; and to rebut any opposing evidence. A Party may be called by an opposing Party and examined as if under cross-examination, whether or not the Party called has testified or intends to testify on his or her own behalf. (c) The Hearing Officer may call and examine any Party or witness and may on his or her own motion introduce exhibits. (d) The Hearing Officer shall control the taking of evidence and other course of proceedings in a hearing and shall exercise that control in a manner best suited to ascertain the facts and safeguard the rights of the Parties. Prior to taking evidence, the Hearing Officer shall define the issues and explain the order in which evidence will be presented; provided that, for good cause the Hearing Officer later may vary the order of presentation as circumstances warrant.

(a) The hearing need not be conducted according to technical rules relating to evidence and witnesses. Any relevant evidence shall be admitted if it is the sort of evidence on which responsible persons are accustomed to rely in the conduct of serious affairs, regardless of the existence of any common law or statutory rule which might make improper the admission of such evidence over objection in civil actions. (b) The rules of privilege shall be recognized to the same extent and applied in the same manner as in the courts of this state. (c) The Hearing Officer may exclude evidence if its probative value is substantially outweighed by the probability that its admission will necessitate undue consumption of time. (d) Hearsay evidence is admissible but shall not be sufficient in itself to support a finding unless it either would be admissible over objection in a civil action or no Party raises an objection to such use. Unless previously waived, an objection or argument that evidence is insufficient in itself to support a finding because of its hearsay character shall be timely if presented at any time before submission of the case for decision.

(b) The Parties participating in a hearing shall be informed of those matters as to which official notice is proposed to be taken and given a reasonable opportunity to show why and the extent to which official notice should or should not be taken. (c) The Hearing Officer or the Director shall state in a decision, order, or on the record the matters as to which official notice has been taken. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.46. Failure to Appear; Relief from Default. (a) Upon the failure of any Party to appear at a duly noticed hearing, the Hearing Officer may enter a default for failure to appear, or proceed in that Party's absence and may recommend whatever decision is warranted by the available evidence, including any lawful inferences that can be drawn from an absence of proof by the non-appearing Party. (b) For good cause and under such terms as are just, the appointed Hearing Officer or the Director may relieve a Party from the effects of any failure to appear and order that a review proceeding be reinstated or reheard. A Party seeking relief from non-appearance shall file a written motion at the earliest opportunity and no later than 10 days following a proceeding of which the Party had actual notice. Such application shall be supported by an affidavit or declaration based on the personal knowledge of the declarant, and copies of the application and any supporting materials shall be served on all other Parties to the proceeding. No application shall be granted unless and until the other Parties have been afforded a reasonable opportunity to make a showing in opposition. An Order reinstating a proceeding or granting a rehearing under this section may be conditioned upon providing reimbursement to the Department and the other Parties for the costs associated with the prior non-appearance. (c) Notwithstanding any application or showing made under subpart (b) of this Rule, neither the Hearing Officer nor the Administrator may reinstate any Request for Review where the underlying Determination of civil penalty or debarment has become final and entered as a court judgment.

(a) If any Person in proceedings before a Hearing Officer disobeys or resists any lawful order or refuses, without substantial justification, to respond to a subpoena, subpoena duces tecum, or refuses to take the oath or affirmation as a witness or thereafter refuses to be examined or is guilty of misconduct during a hearing or so near the place thereof as to obstruct the proceedings, or violates the prohibition against ex parte communications under Rule 07 [Section 232.07] above, the Hearing Officer may do any one or more of the following: (1) certify the facts to the Superior Court in and for the county where the proceedings are held for contempt proceedings pursuant to Government Code section 11455.20; (2) exclude the Person from the hearing room; (3) prohibit the Person from testifying or introducing certain matters in evidence; and/or (4) establish certain facts, claims, or defenses if the Person in contempt is a Party. (b) Either the Hearing Officer by separate order or the Administrator in his or her decision may order a Party, the Party's authorized Representative, or both, to pay reasonable expenses, including attorney's fees, incurred by another Party as a result of bad faith actions or tactics that are frivolous or solely intended to cause unnecessary delay as defined in section 128.5 of the Code of Civil Procedure. Such order or the denial of such an order shall be subject to judicial review in the same manner as a decision of the Administrator on the merits. The order shall be enforceable in the same manner as a money judgment or by the contempt sanction. Note: Authority cited: Section 1777.7, Labor Code; and Section 11400.20, Government Code.

(b) A request for an interpreter for a Party or witness shall be submitted as soon as possible after the requesting Party becomes aware of the need for an interpreter and prior to the commencement of the hearing. The request should include information that (1) will enable the Hearing Officer and Department to obtain an interpreter with appropriate skills; and (2) will assist the Hearing Officer in determining whether the Department or the requesting Party should pay for the cost of the interpreter. (c) Upon receipt of a timely request, the Hearing Officer shall direct the Department to provide an interpreter and shall also decide whether the Department or the requesting Party shall pay the cost of the interpreter, based upon an equitable consideration of all the circumstances, including the requesting Party's ability to pay. (d) A person is qualified to serve as an interpreter if he or she (1) is on the current State Personnel Board List of Certified Administrative Hearing Interpreters maintained pursuant to Government Code section 11435.25; and (2) has also been examined and determined by the Department to be sufficiently knowledgeable of the terminology and procedures generally used in these proceedings. (e) In the event that a qualified interpreter under subpart (d) is unavailable or if there are no certified interpreters for the language in which assistance is needed, the Hearing Officer may qualify and appoint another interpreter to serve as needed in a single hearing or case. (f) Before appointment of an interpreter, the Hearing Officer or a Party may conduct a brief supplemental examination of the prospective interpreter to see if that person has the qualifications necessary to serve as an interpreter, including whether he or she understands terms and procedures generally used in these proceedings, can explain those terms and procedures in English and the other language being used, and can interpret those terms and procedures into the other language. An interpreter shall not have had any prior substantive involvement in the matter under review, and shall disclose to the Hearing Officer and the Parties any actual conflict of interest or appearance of conflict. Any condition that interferes with the objectivity of an interpreter constitutes a conflict of interest. A conflict may exist if an interpreter is an employee of, acquainted with, or related to a Party or witness to the proceeding, or if an interpreter has an interest in the outcome of the proceeding. (g) The Hearing Officer shall disqualify an interpreter if the interpreter cannot understand and interpret the terms and procedures used in the hearing or prehearing conference, has disclosed privileged or confidential communications, or has engaged in conduct which, in the judgment of the Hearing Officer, creates an appearance of bias, prejudice, or partiality. (h) Nothing in this section limits any further rights extended by Evidence Code section 754 to a Party or witness who is deaf or hard of hearing. Note: Authority cited: Section 1777.7, Labor Code. Reference: Section 1777.7, Labor Code. s 232.49. Hearing Record; Recording of Testimony and other Proceedings. (a) The Hearing Officer and the Administrator shall maintain an official record of all proceedings conducted under these Rules. In the absence of a determination under subpart (b) below, all testimony and other proceedings at any hearing shall be recorded by audiotape. However, no recording by audiotape or otherwise shall be required of a duly noticed hearing at which none of the Parties appear. Recorded testimony or other proceedings need not be transcribed unless requested for purposes of further court review of a decision or order in the same case. (b) Upon the application of any Party or upon his or her own motion, the Hearing Officer may authorize the use of a certified court reporter, videotape, or other appropriate means to record the testimony and other proceedings. Any application by a Party under this subpart shall be made at a prehearing conference or by prehearing motion filed no later than 10 days prior to the scheduled date of hearing. Upon the granting of any such application, it shall be the responsibility of the Party or Parties who made the application to procure and pay for the services of a qualified person and any additional equipment needed to record the testimony and proceedings by the requested means. Ordinarily the granting of such application will be conditioned on the applicant's paying for certified copies of the transcript for the official record and for the other Parties. The failure of a requesting Party to comply with this requirement shall not be cause for delaying the hearing on the merits, but instead shall result in the proceedings being tape recorded in accordance with subpart (a). (c) The Parties may, at their own expense, arrange for the recording of testimony and other proceedings through a different means other than the one authorized by the Hearing Officer, provided that it does not in any way interfere with the Hearing Officer's control and conduct of the proceedings, and further provided that, it shall not be regarded as an official record for any purpose absent a stipulation by all of the Parties or order of the Hearing Officer.

Note: Authority cited: Sections 54, 55 and 6319, Labor Code. Reference: Section 6319, Labor Code. s 334. Classification of Violations and Definitions. For purposes of penalty assessments, violations of occupational safety and health standards, violations of California Health and Safety Code Sections 2950 and 25910, orders, special orders and regulations are classified as follows: (a) Regulatory Violation -is a violation, other than one defined as Serious or General that pertains to permit, posting, recordkeeping, and reporting requirements as established by regulation or statute. For example, failure to obtain permit; failure to post citation, poster; failure to keep required records; failure to report industrial accidents, etc. (b) General Violation -is a violation which is specifically determined not to be of a serious nature, but has a relationship to occupational safety and health of employees. (c) Serious Violation. (1) A "serious violation" shall be deemed to exist in a place of employment if there is a substantial probability that death or serious physical harm could result from a violation, including, but not limited to, circumstances where there is a substantial probability that either of the following could result in death or great bodily injury: (A) A serious exposure exceeding an established permissible exposure limit or (B) A condition which exists, or from one or more practices, means, methods, operations, or processes which have been adopted or are in use, in the place of employment. (2) Notwithstanding subsection (c)(1), a serious violation shall not be deemed to exist if the employer can demonstrate that it did not, and could not with the exercise of reasonable diligence, know of the presence of the violation. (3) As used in subsection (c)(1), "substantial probability" refers not to the probability that an accident or exposure will occur as a result of the violation, but rather to the probability that death or serious physical harm will result assuming an accident or exposure occurs as a result of the violation. (4) For Carcinogens -is a violation of any standard, order, or special order respecting the use of a carcinogen, as defined in 8 California Code of Regulations 330(f). However, the violation shall not be considered serious if the employer can demonstrate that he did not, and could not with the exercise of reasonable diligence, know of the presence of the violation or he can demonstrate that the Division should have determined that the violation was minor and resulted in no substantial health hazard. (d) Repeat Violation (1) General -is a violation where the employer has corrected, or indicated correction of an earlier violation, for which a citation was issued, and upon a later inspection is found to have committed the same violation again within a period of three years immediately preceding the latter violation. For the purpose of considering whether a violation is repeated, a repeat citation issued to employers having fixed establishments (e.g., factories, terminals, stores . . .) will be limited to the cited establishment; for employers engaged in businesses having no fixed establishments (e.g., construction, painting, excavation . . .) a repeat violation will be based on prior violations cited within the same Region of the Division. (2) Field Sanitation Violations -Is a violation of the State Field Sanitation Standard, currently set forth in 8 CCR 3457, or of the Federal Field Sanitation Standard, currently set forth in 29 CFR 1928.110, where the employer has corrected, or indicated correction of an earlier violation, for which a citation was issued, and upon a later inspection is found to have committed the same violation within a period of five years immediately preceding the latter violation. For the purpose of considering whether a violation is repeated, a repeat violation will be based on prior violations cited within the State. (e) Willful Violation -is a violation where evidence shows that the employer committed an intentional and knowing, as contrasted with inadvertent, violation, and the employer is conscious of the fact that what he is doing constitutes a violation of a safety law; or, even though the employer was not consciously violating a safety law, he was aware that an unsafe or hazardous condition existed and made no reasonable effort to eliminate the condition. (f) Abatement Date -is the date by which the employer is allowed and required to correct the condition constituting the violation. Note: Authority cited: Sections 54, 55 and 6319, Labor Code. Reference: Sections 6302(i),6319, 6432 and 6712, Labor Code; and Sections 2950 and 25910, Health and Safety Code. s 335. Factors Considered in Assessing Civil Penalties. In the assessment of civil penalties, the following factors shall be considered: (a) The Gravity of the Violation -the Division establishes the degree of gravity of General and Serious violations from its findings and evidence obtained during the inspection/investigation, from its files and records, and other records of governmental agencies pertaining to occupational injury, illness or disease. The degree of gravity of General and Serious violations is determined by assessing and evaluating the following criteria: (1) Severity. (A) General Violation. i. When the safety order violated pertains to employee illness or disease, Severity shall be based upon the degree of discomfort, temporary disability and time loss from normal activity (including work) which an employee is likely to suffer as a result of occupational illness or disease which could result from the violation. Depending on the foregoing, Severity shall be rated as follows: LOW - No time loss from work or normal activity; or minimum discomfort. MEDIUM - Loss of part or all of a day from work or normal activity including time for medical attention; or moderate tem- porary discomfort. HIGH - Loss of more than one day from regular work or normal activity including time for medical attention; or consid- erable temporary discomfort. ii. When the safety order violated does not pertain to employee illness or disease, Severity shall be based upon the type and amount of medical treatment likely to be required or which would be appropriate for the type of injury that would most likely result from the violation. Depending on such treatment, Severity shall be rated as follows: LOW - Requiring first-aid only. MEDIUM - Requiring medical attention but not more than 24-hour hospitalization. HIGH - Requiring more than 24-hour hospitalization. (B) Serious Violation. The Severity of a Serious violation is considered to be HIGH. (2) Extent. i. When the safety order violated pertains to employee illness or disease, Extent shall be based upon the number of employees exposed: LOW - 1 to 5 employees. MEDIUM - 6 to 25 employees. HIGH - 26 or more employees. ii. When the safety order violated does not pertain to employee illness or disease, Extent shall be based upon the degree to which a safety order is violated. It is related to the ratio of the number of violations of a certain order to the number of possibilities for a violation on the premises or site. It is an indication of how widespread the violation is. Depending on the foregoing, Extent is rated as: LOW - When an isolated violation of the standard occurs, or less than 15% of the units are in violation. MEDIUM - When occasional violation of the standard occurs or 15-50% of the units are in violation. HIGH - When numerous violations of the standard occur, or more than 50% of the units are in violation. (3) Likelihood. Likelihood is the probability that injury, illness or disease will occur as a result of the violation. Thus, Likelihood is based on (i) the number of employees exposed to the hazard created by the violation, and (ii) the extent to which the violation has in the past resulted in injury, illness or disease to the employees of the firm and/or industry in general, as shown by experience, available statistics or records. Depending on the above two criteria, Likelihood is rated as: LOW, MODERATE OR HIGH (b) The Size of the Business of the Employer -is based upon the number of individuals employed at the time of the inspection/investigation. Size of the Business is evaluated based upon the following classifications of the number of persons employed: 10 or fewer employees. 10 or fewer employees. 11 to 25 employees. 26 to 60 employees. 61 to 100 employees. More than 100 employees. (c) The Good Faith of the Employer -is based upon the quality and extent of the safety program the employer has in effect and operating. It includes the employer's awareness of CAL/OSHA, and any indications of the employer's desire to comply with the Act, by specific displays of accomplishments. Depending on such safety programs and the efforts of the employer to comply with the Act, Good Faith is rated as: GOOD - Effective safety program. FAIR - Average safety program. POOR - No effective safety program. (d) The History of Previous Violations -is the employer's history of compliance, determined by examining and evaluating the employer's records in the Division's files. Depending on such records, the History of Previous Violations is rated as: GOOD - Within the last three years, no Serious, Repeat, or Willful violations and less than one General or Regulatory viola- tion per 100 employees at the establishment. FAIR - Within the last three years, no Serious, Repeat, or Willful violations and less than 20 General or Regulatory viola- tions per 100 employees at the establishment. POOR - Within the last three years, a Serious, Repeat, or Willful violation or more than 20 General or Regulatory viola- tions per 100 employees at the establishment. For the purpose of this subsection, establishment and the three-year computation, shall have the same meaning as in Section 334(d) of this Article. s 336. Assessment of Civil Penalties. Civil penalties for Regulatory, General, Serious, Repeat, Willful, and Failure to Abate violations shall be assessed in the following manner: (a) Regulatory Violation - (1) In General -Any employer who commits any Regulatory violation (as provided in Section 334(a) of this article) shall be assessed a civil penalty of up to $7000 for each such violation. Except as set forth in parts (2) through (6) of this subsection, a minimum proposed penalty of $500, representing the gravity of the violation, shall be assessed against employers who commit Regulatory violations. The proposed penalty shall be adjusted for Size, Good Faith, and History; however, an abatement credit shall not be granted. (2) For Carcinogens -A minimum proposed penalty of $1,000 for all carcinogen standard regulatory violations, other than reporting use violations, representing the gravity of the violation, shall be assessed against the employers who commit such violations. The proposed penalty shall be adjusted for Size, Good Faith and History; however, an abatement credit shall not be granted. (3) For Carcinogens Failure to Report Use. Any employer who violates a reporting requirement respecting the use of a carcinogen as defined in Title 8 of the California Code of Regulations section 330(f), shall be assessed a minimum proposed civil penalty of $2,500. The proposed penalty shall be adjusted for Size, Good Faith, and History; however, an abatement credit shall not be granted. (4) For Violation of Permit or Registration Requirements. Any employer who violates the permit requirements of article 2, Permits -Excavations, Trenches, Construction and Demolition, and The Underground Use of Diesel Engines in Work in Mines and Tunnels, commencing with section 341 of Title 8 of the California Code of Regulations, or the Registration requirements of article 2.5, Registration -Asbestos-Related Work commencing with section 341.6 of Title 8 of the California Code of Regulations, shall be assessed a minimum proposed civil penalty of $1,250. The proposed penalty shall be adjusted for Size, Good Faith, and History; however, an abatement credit shall not be granted. (5) For Violation of Elevator Permit and Posting Requirements. Any person owning or having custody, management, or operation of an elevator who operates any such elevator without a valid permit, or who fails to post the permit as required, may be assessed a civil penalty pursuant to the provisions of this article of up to $1000. (6) For Failure to Report Serious Injury or Illness, or Death of an Employee - Any employer who fails to timely report an employee's injury or illness, or death, in vioaltion of section 342(a) of Title 8 of the California Code of Regulations, shall be assessed a minimum penalty of $5,000. (b) General Violation -Any employer who violates any occupational safety and health standard, order or special order and such violation is determined to be a General violation (as provided in section 334(b) of this article) may be assessed a civil penalty of up to $7000 for each such violation. Gravity of a General Violation -The Base Penalty of a General violation is determined by evaluating Severity (as provided in section 335(a)(1)(A) of this article). If the Severity is: LOW - The Base Penalty shall be $1,000. MEDIUM - The Base Penalty shall be $1,500. HIGH - The Base Penalty shall be $2,000. The Base Penalty for the General violation determined under this subsection is then subjected to an adjustment for Extent (as provided in section 335(a)(2) of this article). If the Extent is: LOW - 25% of the Base Penalty shall be subtracted. MEDIUM - No adjustment shall be made. HIGH - 25% of the Base Penalty shall be added. The Base Penalty for the General violation thus far determined is further subjected to an adjustment for Likelihood (as provided in section 335(a)(3) of this article). If Likelihood is: LOW - 25% of the Base Penalty shall be subtracted. MEDIUM - No adjustment shall be made. HIGH - 25% of the Base Penalty shall be added. The resulting figure is called the Gravity-based penalty. (c) Serious Violation (1) In General -Any employer who violates any occupational safety and health standard, order, or special order, and such violation is determined to be a Serious violation (as provided in section 334(c)(1) of this article) shall be assessed a civil penalty of up to $25,000 for each such violation. Because of the extreme gravity of a Serious violation an initial base penalty of $18,000 shall be assessed. The Base Penalty for the Serious violation determined under this subsection is then subjected to an adjustment for Extent (as provided in section 335(a)(2) of this article). If the Extent is: LOW - 25% of the Base Penalty shall be subtracted. MEDIUM - No adjustment shall be made. HIGH - 25% of the Base Penalty shall be added. The Base Penalty for the Serious violation thus far determined is further subjected to an adjustment for Likelihood (as provided in section 335(a)(3) of this article). If Likelihood is: LOW - 25% of the Base Penalty shall be subtracted. MEDIUM - No adjustment shall be made. HIGH - 25% of the Base Penalty shall be added. The resulting figure is called the Gravity-based penalty. (2) For Carcinogens -Any employer who violates any occupational safety and health standard, order, or special order respecting the use of a carcinogen, and such violation is determined to be a Serious violation (as provided in section 334(c)(4) of this article) shall be assessed a total civil penalty of $2000 for each such violation. This penalty is not subject to adjustment. (3) Serious Violation Causing Death or Serious Injury, Illness or Exposure -If the employer commits a Serious violation and the Division has determined that the violation caused death or serious injury, illness or exposure as defined pursuant to Labor Code section 6302, the penalty shall not be reduced pursuant to this subsection, except the penalty may be reduced for Size as set forth in subsection (d)(1) of this section. The penalty shall not exceed $25,000. (4) Operation of an Elevator in an Unsafe Condition or in Violation of an Order Prohibiting Use. Any person owning or having custody, management or operation of an elevator who operates or permits the operation of the elevator in a condition which is dangerous to life or the safety of any person, or who operates or permits the operation of the elevator in violation of any Order Prohibiting Use issued by the Division, may be assessed a civil penalty pursuant to the provisions of this article of up to $2000. (5) For Tower Cranes -Any employer who violates any tower crane standard, order or special order and such violation is determined to be a serious violation (as provided in section 334(c)(1) of this article) shall be assessed a penalty of $2,000. The penalty shall not be subject to adjustment as set forth in subsections (d) and (e) of this section. (d) Further Adjustment of Regulatory, General, and Serious Violations -Subject to the provisions of parts (5) through (9) of this subsection, the Gravity-based Penalty established under either subsection (a), (b) or (c) of this section, shall be appropriately adjusted by giving due consideration to the following factors: (1) The Size of the Business If the Size of the Business (as provided under section 335(b) of this article) is: 10 or fewer - 40% of the Gravity-based employees Penalty shall be subtracted. 11-25 - 30% of the Gravity-based employees Penalty shall be subtracted. 26-60 - 20% of the Gravity-based employees Penalty shall be subtracted. 61-100 - 10% of the Gravity-based employees Penalty shall be subtracted. More than - No adjustment shall be made. 100 employees (2) The Good Faith of the Employer -If the Good Faith of the Employer (as provided under section 335(c) of this article) is: GOOD - 30% of the Gravity-based Penalty shall be subtracted. FAIR - 15% of the Gravity-based Penalty shall be subtracted. POOR - No adjustment shall be made. (3) The History of Previous Violations -If the employer's History of Compliance (as provided under section 335(d) of this article) is: GOOD - 10% of the Gravity-based Penalty shall be subtracted. FAIR - 5% of the Gravity-based Penalty shall be subtracted. POOR - No adjustment shall be made. Following the preceding adjustments of the Gravity-based Penalty, the resultant penalty is termed Adjusted Penalty. (4) If an employer cited for a violation of a safety and health provision within title 8 of the California Code of Regulations was, at the time of citation, making a good faith effort to abate the alleged violation, pursuant to written recommendations of a Consultant of the CAL/OSHA Consultation Service, the following penalty adjustments may apply: (A) General Violation. All penalties assessed for such General violations may be waived by the Division. (B) Serious Violation. All penalties for such Serious violations may be subject to an additional adjustment reducing the proposed penalty 50%. (5) Serious Violations Respecting the Use of a Carcinogen -The penalty for any Serious violation respecting the use of a carcinogen as set forth in subsection (c)(2) of this section is not subject to adjustment pursuant to this subsection and shall not be otherwise reduced. (6) Regulatory Violations of the Permit and Registration Requirements -The minimum penalty for any Regulatory violation of the permit or registration requirements as set forth in subsection (a)(4) of this section is $250. (7) Serious Violations Causing Death or Serious Injury, Illness or Exposure - Subject to the provisions of subsection (c)(3) of this section, the penalty for any Serious violation determined by the Division to have caused death or serious injury, illness or exposure as defined pursuant to Labor Code section 6302, shall not be adjusted pursuant to this subsection, except for Size set forth in part (1) of this subsection. (8) Injury Prevention Program -The penalty for any Serious violation shall not be subject to adjustment pursuant to this subsection other than for Size as set forth in part (1) of this subsection where the employer does not have an operative injury prevention program as set forth in Labor Code section 6401.7 and applicable regulations of the California Occupational Safety and Health Standards Board. (9) False Declarations of Abatement -Subject to the provisions of subsection (e) of this section, where it is determined after reinspection that the employer has not complied with the abatement requirements of the Division and employer has previously submitted a statement affirming compliance therewith, the recomputed penalty shall not be adjusted pursuant to this subsection, except for Size as set forth in part (1) of this subsection. (10) No civil penalty shall be assessed against any new employer for a period of one year after the date the new employer establishes a business in the state for a regulatory or general violation of the Injury and Illness Prevention Program Standard adopted pursuant to Labor Code section 6401.7 and applicable regulations of the California Occupational Safety and Health Standards Board, if the employer has made a good faith effort to comply with the requirement set forth therein. (11) No civil penalty shall be assessed against an employer who adopts, posts, and implements in good faith the Model Injury and Illness Prevention Program for Non-High-Hazard Employment prepared by the Division for a first violation of the Injury and Illness Prevention Program standard adopted pursuant to Labor Code section 6401.7 and applicable regulations of the California Occupational Safety and Health Standards Board. (12) For an employer who commits a repeat violation (as provided under section 334(d) of this article), the penalty shall not be subject to adjustment pursuant to this subsection, other than for Size as set forth in part (1) of this subsection. (e) Abatement Credit for General and Serious Violations -The Adjusted Penalty for General and Serious violations is reduced by 50% on the presumption that the employer will correct the violations by the abatement date. The resultant penalty is termed Proposed Penalty. The following types of violations are not subject to an abatement credit: (1) Violations designated as Repeat or Willful; (2) Serious violations for which extent and likelihood are rated high; (3) Serious violations respecting the use of a carcinogen; and (4) Serious violation causing death or serious injury, illness or exposure as defined pursuant to Labor Code section 6302. (f) Penalty for Failure to Abate Regulatory, General or Serious Violations -If the employer fails to abate the violation by the date permitted for its correction or fails to submit to the Division a signed statement of abatement of a violation within ten working days of the date set by the Division for correction of the violative condition, any abatement credit extended pursuant to subsection (e) of this Section shall be rescinded and this amount assessed as part of the failure to abate penalty. In addition, a penalty shall be assessed that is based upon the initial Gravity-based penalty for each calendar day that the previously cited violation continues unabated after expiration of the abatement period. Subject to the provisions of part (1) hereof, the Gravity-based penalty is reduced by the reevaluated adjustment factors. The adjustment factors of Size, Good Faith, and History shall be determined by evaluation of the circumstances at the time of the subsequent inspection when the failure to abate is discovered. The daily additional penalty for failure to abate a violation shall not exceed $15,000. Limitations: (1) Except (A) where the gravity of the violation is high and exposure to employees is continuous, or (B) the employer has exhibited a high degree of negligence in failing to correct the violation, the daily penalty for failure to abate a Regulatory or General violation may be further reduced up to 90% for the first 120 days the violation continues to exist and up to 50% thereafter where the violation does not bear a direct relationship on employee health and safety. The daily penalty for a Serious violation may be reduced up to 50% where the adjustment factors calculated pursuant to subsection (c) of this section are Low and the History and Good Faith calculated pursuant to subsection (d) of this section are Good. (2) When a violation consisted of a number of instances and upon subsequent inspection some instances are found to have been abated and others have not, the daily penalty shall be calculated in proportion to the extent that the violation has been abated. (3) Failure to Abate a Serious Violation Causing Death or Serious Injury, Illness or Exposure -If the employer fails to abate a Serious violation and the Division has determined that the failure to abate caused death or serious injury, illness, or exposure as defined pursuant to Labor Code section 6302, the penalty shall not be adjusted pursuant to this subsection, except for Size as set forth in subsection (d)(1) of this section. (4) Failure to Abate a Serious Violation of Crane Standard, Order, or Special Order Causing Death or Serious Injury -If the employer fails to abate a serious violation of a crane standard, order, or special order and the Division has determined that the failure to abate caused death or serious injury as defined pursuant to Labor Code 6302, the penalty shall be $14,000 for each calendar day. The penalty is not subject to adjustment. (5) False Declaration of Abatement -If it is determined after reinspection that the employer has not complied with the abatement requirements of the Division, and the employer has previously submitted a statement affirming compliance therewith, the recomputed penalty shall not be adjusted pursuant to this subsection, except for Size pursuant to part (1) of subsection (d) of this section. (g) Repeat Violation - (1) In General -If a Regulatory, General, or Serious violation is repeated (as provided under section 334(d) of this article) the Proposed Penalty is adjusted upward as follows: 1st repeat - the Proposed Penalty is multiplied by two. 2nd repeat - the Proposed Penalty is multiplied by four. 3rd repeat - the Proposed Penalty is multiplied by ten. The resultant penalty shall not exceed $70,000. (2) For Carcinogens -If a Serious violation respecting the use of a carcinogen or a Regulatory violation concerning a reporting requirement respecting the use of a carcinogen is repeated (as provided in section 334(d) of this article), the total civil penalty shall be as follows: (A) For repeated Regulatory violations concerning a reporting requirement. 1st repeat - $5,000 2nd repeat - $10,000 3rd repeat - $20,000 (B) For repeated Serious violations respecting the use of a carcinogen. 1st repeat - $10,000 2nd repeat - $20,000 3rd repeat - $40,000 These penalties are not subject to adjustment. (3) Repeated Violation Causing Death or Serious Injury, Illness or Exposure - The computation of the Proposed Penalty for a repeated violation shall not be subject to reduction, other than the Size pursuant to part (1) of subsection (d) of this section, where the violation is determined by the Division to have caused death or serious injury, illness or exposure within the meaning of Labor Code section 6302. (h) Willful Violation -If a Regulatory, General, or Serious violation is determined to be willful (as provided under section 334(e) of this article) the Proposed Penalty is adjusted upward as follows: Regulatory, General and Serious -the Proposed Penalty is multiplied by five. However, the penalty for any willful violation shall not be less than $5,000 and shall not exceed $70,000. (1) Willful Violation Causing Death or Serious Injury, Illness or Exposure -The computation of the Proposed Penalty for a willful violation shall not be subject to reduction, other than the Size pursuant to part (1) of subsection (d) of this section, where the violation is determined by the Division to have caused death or serious injury, illness or exposure within the meaning of Labor Code section 6302. (i) Serious Repeated or Willful Repeated Violation of Crane Standard, Order, or Special Order Causing Death or Serious Injury -If the employer commits a serious repeated or willful repeated violation of a crane standard, order, or special order, and the Division has determined that the violation caused death or serious injury as defined pursuant to Labor Code 6302, the penalty shall be $140,000. This penalty is not subject to adjustment. (j) Rounding of the Fractions Amounts of the civil penalties are rounded down to the next whole dollar during the calculation stages, and final figures are adjusted downward to the next lower five dollar ($5) value. (k) Multiple Violations Pertaining To A Single Hazard. When a single hazard is the subject matter of multiple violations resulting in civil penalties, the Division may, in its discretion, depart from the preceding criteria to mitigate the cumulative effect of such penalties. (1) This subsection does not apply to any penalty assessed for a Serious, Willful or Repeated violation or a failure to abate a Serious violation where such violation or violations have been determined by the Division to have caused death or serious injury, illness or exposure pursuant to Labor Code section 6302. This subsection does not apply to any Regulatory, General or Serious violation where the employer does not have an operative injury prevention program as set forth in subsection (d) of this section.

On multi-employer worksites, both construction and non-construction, citations may be issued only to the following categories of employers when the Division has evidence that an employee was exposed to a hazard in violation of any requirement enforceable by the Division: (a) The employer whose employees were exposed to the hazard (the exposing employer); (b) The employer who actually created the hazard (the creating employer); (c) The employer who was responsible, by contract or through actual practice, for safety and health conditions on the worksite; i.e., the employer who had the authority for ensuring that the hazardous condition is corrected (the controlling employer); or (d) The employer who had the responsibility for actually correcting the hazard (the correcting employer). Note: The employers listed in subsections (b) through (d) may be cited regardless of whether their own employees were exposed to the hazard. Note: Authority cited: Sections 54 and 55, Labor Code. Reference: Sections 50.7, 6317, 6400, 6401, 6402, 6403, 6404, 6405, 6406 and 6407, Labor Code. s 336.11. Determination of Applicability of Defenses. Prior to issuing any citation to an exposing employer, the Division shall first determine whether available information indicates that the employer meets each of the defenses listed below. If the Division concludes that all five defenses have been met, the citation shall not be issued. These defenses are: (a) The employer did not create the hazard. (b) The employer did not have the responsibility or the authority to have the hazard corrected. (c) The employer did not have the ability to correct or remove the hazard. (d) The employer can demonstrate that the creating, the controlling and/or the correction employers, as appropriate, were specifically notified or were aware of the hazards to which his/her employees were exposed. (e) The employer took appropriate feasible steps to protect his/her employees from the hazard, instructed them to recognize the hazard and, where necessary, informed them how to avoid the dangers associated with it. For the purposes of this section, where an extreme hazard is involved, appropriate feasible steps include removing the employer's employees from the job, if there is no other way to protect them from the hazard. Note: Authority cited: Sections 54 and 55, Labor Code. Reference: Sections 50.7, 6317, 6400, 6401, 6402, 6403, 6404, 6405, 6406 and 6407, Labor Code. s 337. Development and Maintenance of List. (a) Establishment of Initial List. Substances designated in the sources specified in Labor Code section 6382(b) shall be considered in formulating the initial list. The Director shall presume all such substances to be potentially hazardous to human health when present occupationally except those which the Director determines do not pose any adverse acute or chronic risk to human health as present occupationally. Those substances which do not pose any risk shall be removed from the list. Evidence of risk shall include any immediate or long-term adverse effect which causes impairment of function, alteration of structure, or increased susceptibility to disease or contributes to adverse effects of other substances. In making a determination of risk, the Director shall consider available scientific data including, but not limited to, data from human epidemiological studies, data from short-term in vitro studies, and data from animal bioassay tests. Animal bioassay data is admissible and generally indicative of potential effects in humans. For purposes of this regulation, substances are present occupationally when there is a possibility of exposure either as a result of normal work operations or a reasonably foreseeable emergency resulting from workplace operations. A reasonably foreseeable emergency is one which a reasonable person should anticipate based on usual work conditions, a substance's particular chemical properties (e.g., potential for explosion, fire, reactivity), and the potential for human health hazards. A reasonably foreseeable emergency includes, but is not limited to, spills, fires, explosions, equipment failure, rupture of containers, or failure of control equipment which may or do result in a release of a hazardous substance into the workplace. (b) Administrative Procedure Followed by the Director for the Development of the Initial List. The Director shall hold a public hearing concerning the initial list. The record will remain open 30 days after the public hearing for additional written comment. Requests to exempt a substance in a particular physical state, volume, or concentration from the provisions of Labor Code sections 6390 to 6399.2 may be made at this time. If no comments in opposition to such a request are made at the public hearing or received during the comment period, or if the Director can find no valid reason why the request should not be considered, it will be incorporated during the Director's preparation of the list. After the public comment period the Director shall formulate the initial list and send it to the Standards Board for approval. After receipt of the list or a modified list from the Standards Board, the Director will adopt the list and file it with the Office of Administrative Law. (c) Concentration Requirement. In determining whether the concentration requirement of a substance should be changed pursuant to Labor Code section 6383, the Director shall consider valid and substantial evidence. Valid and substantial evidence shall consist of clinical evidence or toxicological studies including, but not limited to, animal bioassay tests, short-term in vitro tests, and human epidemiological studies. Upon adoption, a regulation indicating the concentration requirement for a substance shall consist of a footnote on the list. (d) Procedures for Modifying the List. The Director will consider petitions from any member of the public to modify the list or the concentration requirements, pursuant to the procedures specified in Government Code section 11347.1. With petitions to modify the list, the Director shall make any necessary deletions or additions in accordance with the procedures herein set forth for establishing the list. The Director will review the existing list at least every two years and shall make any necessary additions or deletions in accordance with the procedures herein set forth for establishing the list. (e) Criteria for Modifying the List. Petitions to add or remove a substance on the list, modify the concentration level of a substance, or reference when a particular substance is present in a physical state which does not pose any human health risk must be accompanied with relevant and sufficient scientific data which may include, but is not limited to, short-term tests, animal studies, human epidemiological studies, and clinical data. If the applicant does not include the complete content of a referenced study or other document, there must be sufficient information to permit the Director to identify and obtain the referenced material. The petitioner bears the burden of justifying any proposed modification of the list. The Director shall consider all evidence submitted, including negative and positive evidence. All evidence must be based on properly designed studies for toxicological endpoints indicating adverse health effects in humans, e.g., carcinogenicity, mutagenicity, neurotoxicity, organ damage/effects. For purposes of this regulation, animal data is admissible and generally indicative of potential effects in humans. The absence of a particular category of studies shall not be used to prove the absence of risk. Negative results generally indicate the absence of statistically positive results in appropriate studies. As all tests for toxicological effects have inherent insensitivities, negative results must be reevaluated in light of the limits of sensitivity of each study, its test design, and the protocol followed. In evaluating different results among proper tests, as a general rule, positive results shall be given more weight than negative results for purposes of including a substance on the list or modifying the list in reference to concentration, physical state or volume, so that appropriate information may be provided regarding those positive results. In each case, the relative sensitivity of each test shall be a factor in resolving such conflicts. Note: Authority cited: Section 6380, Labor Code.

The State Plan incorporates the provisions of Proposition 65, as approved by Federal OSHA on June 6, 1997. This approval specifically placed certain conditions with regard to occupational exposures on Proposition 65, including that it does not apply to the conduct of manufacturers occurring outside the State of California. The approval also provides that an employer may use the means of compliance in the general hazard communication requirements to comply with Proposition 65. It also requires that supplemental enforcement is subject to the supervision of the California Occupational Safety and Health Administration. Accordingly, any settlement, civil complaint, or substantive court orders in this matter must be submitted to the Attorney General." (c) A Supplemental Enforcer or Public Prosecutor who commences a Supplemental Enforcement Matter shall serve a file-endorsed copy of the complaint upon the Attorney General within ten days after filing with the Court. (d) A Supplemental Enforcer or Public Prosecutor shall serve upon the Attorney General a copy of any motion, or opposition to a motion for summary judgment or summary adjudication of issues, a demurrer, motion for preliminary or injunctive relief, or other dispositive motion, and all memoranda of points and authorities in support of or opposing such motions. These materials shall be served upon the Attorney General on the same day which they are served on the opposing party. A Supplemental Enforcer or Public Prosecutor shall serve upon the Attorney General any decision or order of a court granting or denying summary adjudication, a demurrer, preliminary or final injunctive relief, penalties, or damages relating to a Supplemental Enforcement Matter within five working days after receipt. (e) A Supplemental Enforcer or Public Prosecutor who agrees to a settlement of a Supplemental Enforcement Matter shall serve the settlement upon the Attorney General within two working days after the agreement is signed by the parties. Where the settlement is submitted to a court for its approval, the Supplemental Enforcer or Public Prosecutor shall notify the court in writing upon presentation of the settlement of its submission to the Attorney General pursuant to this regulation. The submission to the Attorney General shall contain the entire agreement between the parties. (f) When this section requires that any document or information be provided to the Attorney General, service shall be in a manner prescribed by Code of Civil Procedure s 1010 et seq. The envelope in which the document is transmitted shall state prominently "Hazard Communication Standard/Proposition 65 Supplemental Enforcement Matter." The Attorney General may then specify that further documents be served upon a particular office and deputy. (g) The special procedures set forth in subsections (a) through (f) shall be followed for motions or other applications for judicial enforcement of any existing or future settlement agreements pertaining to Proposition 65, with reference to occupational exposures. (h) Where, in the judgment of the Director and the Attorney General, a Supplemental Enforcer or Public Prosecutor has not complied with the provisions of this section, or the provisions of the OSHA approval decision of June 6, 1997, the Attorney General may seek to intervene in the action, or take such actions within his authority as he deems appropriate to assure compliance.

(B) Only one Project Permit is required per project as long as the Project Permit holder continues to act in the role of Project Administrator, even though the project may have more than one employer fitting the description of a Project Administrator. If the holder of the current Project Permit no longer continues to act in the role of Project Administrator, that Project Permit is no longer valid, and no project work shall continue until a new Project Permit has been issued.

Appendix A 40 CFR Part 763, Appendix C to Subpart E, Asbestos Model Accreditation Plan. I. Asbestos Model Accreditation Plan for States The Asbestos Model Accreditation Plan (MAP) for States has eight components: (A) Definitions (B) Initial Training (C) Examinations (D) Continuing Education (E) Qualifications (F) Recordkeeping Requirements for Training Providers (G) Deaccreditation (H) Reciprocity A. Definitions For purposes of Appendix C: 1. "Friable asbestos-containing material (ACM)" means any material containing more than one percent asbestos which has been applied on ceilings, walls, structural members, piping, duct work, or any other part of a building, which when dry, may be crumbled, pulverized, or reduced to powder by hand pressure. The term includes non-friable asbestos-containing material after such previously non-friable material becomes damaged to the extent that when dry it may be crumbled, pulverized, or reduced to powder by hand pressure. 2. "Friable asbestos-containing building material (ACBM)" means any friable ACM that is in or on interior structural members or other parts of a school or public and commercial building. 3. "Inspection" means an activity undertaken in a school building, or a public and commercial building, to determine the presence or location, or to assess the condition of, friable or non-friable asbestos-containing building material (ACBM) or suspected ACBM, whether by visual or physical examination, or by collecting samples of such material. This term includes reinspections of friable and non-friable known or assumed ACBM which has been previously identified. The term does not include the following: a. Periodic surveillance of the type described in 40 CFR 763.92(b) solely for the purpose of recording or reporting a change in the condition of known or assumed ACBM; b. Inspections performed by employees or agents of Federal, State, or local government solely for the purpose of determining compliance with applicable statutes or regulations; or c. visual inspections of the type described in 40 CFR 763.90(i) solely for the purpose of determining completion of response actions. 4. "Major fiber release episode" means any uncontrolled or unintentional disturbance of ACBM, resulting in a visible emission, which involves the falling or dislodging of more than 3 square or linear feet of friable ACBM. 5. "Minor fiber release episode" means any uncontrolled or unintentional disturbance of ACBM, resulting in a visible emission, which involves the falling or dislodging of 3 square or linear feet or less of friable ACBM. 6. "Public and commercial building" means the interior space of any building which is not a school building, except that the term does not include any residential apartment building of fewer than 10 units or detached single-family homes. The term includes, but is not limited to: industrial and office buildings, residential apartment buildings and condominiums of 10 or more dwelling units, government-owned buildings, colleges, museums, airports, hospitals, churches, preschools, stores, warehouses and factories. Interior space includes exterior hallways connecting buildings, porticos, and mechanical systems used to condition interior space. 7. "Response action" means a method, including removal, encapsulation, enclosure, repair, and operation and maintenance, that protects human health and the environment from friable ACBM. 8. "Small-scale, short-duration activities (SSSD)" are tasks such as, but not limited to: a. Removal of asbestos-containing insulation on pipes. b. Removal of small quantities of asbestos-containing insulation on beams or above ceilings. c. Replacement of an asbestos-containing gasket on a valve. d. Installation or removal of a small section of drywall. e. Installation of electrical conduits through or proximate to asbestos-containing materials. SSSD can be further defined by the following considerations: f. Removal of small quantities of ACM only if required in the performance of another maintenance activity not intended as asbestos abatement. g. Removal of asbestos-containing thermal system insulation not to exceed amounts greater than those which can be contained in a single glove bag. h. Minor repairs to damaged thermal system insulation which do not require removal. i. Repairs to a piece of asbestos-containing wallboard. j. Repairs, involving encapsulation, enclosure, or removal, to small amounts of friable ACM only if required in the performance of emergency or routine maintenance activity and not intended solely as asbestos abatement. Such work may not exceed amounts greater than those which can be contained in a single prefabricated mini-enclosure. Such an enclosure shall conform spatially and geometrically to the localized work area, in order to perform its intended containment function. B. Initial Training Training requirements for purposes of accreditation are specified both in terms of required subjects of instruction and in terms of length of training. Each initial training course has a prescribed curriculum and number of days of training. One day of training equals 8 hours, including breaks and lunch. Course instruction must be provided by EPA or State-approved instructors. EPA or State instructor approval shall be based upon a review of the instructor's academic credentials and/or field experience in asbestos abatement. Beyond the initial training requirements, individual States may wish to consider requiring additional days of training for purposes of supplementing hands-on activities or for reviewing relevant state regulations. States also may wish to consider the relative merits of a worker apprenticeship program. Further, they might consider more stringent minimum qualification standards for the approval of training instructors. EPA recommends that the enrollment in any given course be limited to 25 students so that adequate opportunities exist for individual hands-on experience. States have the option to provide initial training directly or approve other entities to offer training. The following requirements are for the initial training of persons required to have accreditation under TSCA Title II. Training requirements for each of the five accredited disciplines are outlined below. Persons in each discipline perform a different job function and distinct role. Inspectors identify and assess the condition of ACBM, or suspect ACBM. Management planners use data gathered by inspectors to assess the degree of hazard posed by ACBM in schools to determine the scope and timing of appropriate response actions needed for schools. Project designers determine how asbestos abatement work should be conducted. Lastly, workers and contractor/supervisors carry out and oversee abatement work. In addition, a recommended training curriculum is also presented for a sixth discipline, which is not federally-accredited, that of "Project Monitor." Each accredited discipline and training curriculum is separate and distinct from the others. A person seeking accreditation in any of the five accredited MAP disciplines cannot attend two or more courses concurrently, but may attend such courses sequentially. In several instances, initial training courses for a specific discipline (e.g., workers, inspectors) require hands-on training. For asbestos abatement contractor/supervisors and workers, hands-on training should include working with asbestos-substitute materials, fitting and using respirators, use of glovebags, donning protective clothing, and constructing a decontamination unit as well as other abatement work activities. 1. Workers A person must be accredited as a worker to carry out any of the following activities with respect to friable ACBM in a school or public and commercial building: (1) A response action other than a SSSD activity, (2) a maintenance activity that disturbs friable ACBM other than a SSSD activity, or (3) a response action for a major fiber release episode. All persons seeking accreditation as asbestos abatement workers shall complete at least a 4-day training course as outlined below. The 4-day worker training course shall include lectures, demonstrations, at least 14 hours of hands-on training, individual respirator fit testing, course review, and an examination. Hands-on training must permit workers to have actual experience performing tasks associated with asbestos abatement. A person who is otherwise accredited as a contractor/supervisor may perform in the role of a worker without possessing separate accreditation as a worker. Because of cultural diversity associated with the asbestos workforce, EPA recommends that States adopt specific standards for the approval of foreign language courses for abatement workers. EPA further recommends the use of audio-visual materials to complement lectures, where appropriate. The training course shall adequately address the following topics: (a) Physical characteristics of asbestos. Identification of asbestos, aerodynamic characteristics, typical uses, and physical appearance, and a summary of abatement control options. (b) Potential health effects related to asbestos exposure. The nature of asbestos-related diseases; routes of exposure; dose-response relationships and the lack of a safe exposure level; the synergistic effect between cigarette smoking and asbestos exposure; the latency periods for asbestos-related diseases; a discussion of the relationship of asbestos exposure to asbestosis, lung cancer, mesothelioma, and cancers of other organs.

Conducting visual inspections: This workshop could consist, ideally, of an interactive video in which a participant is "taken through" a work area and asked to make notes of what is seen. A series of questions will be asked which are designed to stimulate a person's recall of the area. This workshop could consist of a series of two or three videos with different site conditions and different degrees of cleanliness. C. Examinations 1. Each State shall administer a closed book examination or designate other entities such as State-approved providers of training courses to administer the closed-book examination to persons seeking accreditation who have completed an initial training course. Demonstration testing may also be included as part of the examination. A person seeking initial accreditation in a specific discipline must pass the examination for that discipline in order to receive accreditation. For example, a person seeking accreditation as an abatement project designer must pass the State's examination for abatement project designer. States may develop their own examinations, have providers of training courses develop examinations, or use standardized examinations developed for purposes of accreditation under TSCA Title II. In addition, States may supplement standardized examinations with questions about State regulations. States may obtain commercially developed standardized examinations, develop standardized examinations independently, or do so in cooperation with other States, or with commercial or non-profit providers on a regional or national basis. EPA recommends the use of standardized, scientifically-validated testing instruments, which may be beneficial in terms of both promoting competency and in fostering accreditation reciprocity between States. Each examination shall adequately cover the topics included in the training course for that discipline. Each person who completes a training course, passes the required examination, and fulfills whatever other requirements the State imposes must receive an accreditation certificate in a specific discipline. Whether a State directly issues accreditation certificates, or authorizes training providers to issue accreditation certificates, each certificate issued to an accredited person must contain the following minimum information: a. A unique certificate number b. Name of accredited person c. Discipline of the training course completed. d. Dates of the training course. e. Date of the examination. f. An expiration date of 1 year after the date upon which the person successfully completed the course and examination. g. The name, address, and telephone number of the training provider that issued the certificate. h. A statement that the person receiving the certificate has completed the requisite training for asbestos accreditation under TSCA Title II. States or training providers who reaccredit persons based upon completion of required refresher training must also provide accreditation certificates with all of the above information, except the examination date may be omitted if a State does not require a refresher examination for reaccreditation. Where a State licenses accredited persons but has authorized training providers to issue accreditation certificates, the State may issue licenses in the form of photo-identification cards. Where this applies, EPA recommends that the State licenses should include all of the same information required for the accreditation certificates. A State may also choose to issue photo-identification cards in addition to the required accreditation certificates. Accredited persons must have their initial and current accreditation certificates at the location where they are conducting work. 2. The following are the requirements for examination in each discipline: a. Worker: i. 50 multiple-choice questions ii. Passing score: 70 percent correct b. Contractor/Supervisor: i. 100 multiple-choice questions ii. Passing score: 70 percent correct c. Inspector: i. 50 Multiple-choice questions ii. Passing score: 70 percent correct d. Management Planner: i. 50 Multiple-choice questions ii. Passing score: 70 percent correct e. Project Designer: i. 100 multiple-choice questions ii. Passing score: 70 percent correct D. Continuing Education For all disciplines, a State's accreditation program shall include annual refresher training as a requirement for reaccreditation as indicated below: 1. Workers: One full day of refresher training. 2. Contractor/Supervisors: One full day of refresher training. 3. Inspectors: One half-day of refresher training. 4. Management Planners: One half-day of inspector refresher training and one half-day of refresher training for management planners. 5. Project Designers: One full day of refresher training. The refresher courses shall be specific to each discipline. Refresher courses shall be conducted as separate and distinct courses and not combined with any other training during the period of the refresher course. For each discipline, the refresher course shall review and discuss changes in Federal, State, and local regulations, developments in state-of-the-art procedures, and a review of key aspects of the initial training course as determined by the State. After completing the annual refresher course, persons shall have their accreditation extended for an additional year from the date of the refresher course. A State may consider requiring persons to pass reaccreditation examinations at specific intervals (for example, every 3 years). EPA recommends that States formally establish a 12-month grace period to enable formerly accredited persons with expired certificates to complete refresher training and have their accreditation status reinstated without having to re-take the initial training course. E. Qualifications In addition to requiring training and an examination, a State may require candidates for accreditation to meet other qualification and/or experience standards that the State considers appropriate for some or all disciplines. States may choose to consider requiring qualifications similar to the examples outlined below for inspectors, management planners and project designers. States may modify these examples as appropriate. In addition, States may want to include some requirements based on experience in performing a task directly as a part of a job or in an apprenticeship role. They may also wish to consider additional criteria for the approval of training course instructors beyond those prescribed by EPA. 1. Inspectors: Qualifications -possess a high school diploma. States may want to require an Associate's Degree in specific fields (e.g., environmental or physical sciences). 2. Management Planners: Qualifications -Registered architect, engineer, or certified industrial hygienist or related scientific field. 3. Project Designers: Qualifications -registered architect, engineer, or certified industrial hygienist. 4. Asbestos Training Course Instructor: Qualifications -academic credentials and/or field experience in asbestos abatement. EPA recommends that States prescribe minimum qualification standards for training instructors employed by training providers. F. Recordkeeping Requirements for Training Providers All approved providers of accredited asbestos training courses must comply with the following minimum recordkeeping requirements. 1.

A training provider must retain copies of all instructional materials used in the delivery of the classroom training such as student manuals, instructor notebooks and handouts. 2. Instructor qualifications. A training provider must retain copies of all instructors' resumes, and the documents approving each instructor issued by either EPA or a State. Instructors must be approved by either EPA or a State before teaching courses for accreditation purposes. A training provider must notify EPA or the State, as appropriate, in advance whenever it changes course instructors. Records must accurately identify the instructors that taught each particular course for each date that a course is offered. 3. Examinations. A training provider must document that each person who receives an accreditation certificate for an initial training course has achieved a passing score on the examination. These records must clearly indicate the date upon which the exam was administered, the training course and discipline for which the exam was given, the name of the person who proctored the exam, a copy of the exam, and the name and test score of each person taking the exam. The topic and dates of the training course must correspond to those listed on that person's accreditation certificate. States may choose to apply these same requirements to examinations for refresher training courses. 4. Accreditation certificates. The training providers or States, whichever issues the accreditation certificate, shall maintain records that document the names of all persons who have been awarded certificates, their certificate numbers, the disciplines for which accreditation was conferred, training and expiration dates, and the training location. The training provider or State shall maintain the records in a manner that allows verification by telephone of the required information. 5. Verification of certificate information. EPA recommends that training providers of refresher training courses confirm that their students possess valid accreditation before granting course admission. EPA further recommends that training providers offering the initial management planner training course verify that students have met the prerequisite of possessing valid inspector accreditation at the time of course admission. 6. Records retention and access. (a) The training provider shall maintain all required records for a minimum of 3 years. The training provider, however, may find it advantageous to retain these records for a longer period of time. (b) The training provider must allow reasonable access to all of the records required by the MAP, and to any other records which may be required by States for the approval of asbestos training providers or the accreditation of asbestos training courses, to both EPA and to State Agencies, on request. EPA encourages training providers to make this information equally accessible to the general public. (c) If a training provider ceases to conduct training, the training provider shall notify the approving government body (EPA or the State) and give it the opportunity to take possession of that providers asbestos training records. G. Deaccreditation 1. States must establish criteria and procedures for deaccrediting persons accredited as workers, contractor/supervisors, inspectors, management planners, and project designers. States must follow their own administrative procedures in pursuing deaccreditation actions. At a minimum, the criteria shall include: (a) Performing work requiring accreditation at a job site without being in physical possession of initial and current accreditation certificates; (b) Permitting the duplication or use of one's own accreditation certificate by another; (c) Performing work for which accreditation has not been received; or (d) Obtaining accreditation from a training provider that does not have approval to offer training for the particular discipline from either EPA or from a State that has a contractor accreditation plan at least as stringent as the EPA MAP. EPA may directly pursue deaccreditation actions without reliance on State deaccreditation or enforcement authority or actions. In addition to the above-listed situations, the Administrator may suspend or revoke the accreditation of persons who have been subject to a final order imposing a civil penalty or convicted under section 16 of TSCA, 15 U.S.C. 2615 or 2647, for violations of 40 CFR part 763, or section 113 of the Clean Air Act, 42 U.S.C. 7413, for violations of 40 CFR part 61, subpart M. 2. Any person who performs asbestos work requiring accreditation under section 206(a) of TSCA, 15 U.S.C. 2646(a), without such accreditation is in violation of TSCA. The following persons are not accredited for purposes of section 206(a) of TSCA: (a) Any person who obtains accreditation through fraudulent representation of training or examination documents; (b) Any person who obtains training documentation through fraudulent means; (c) Any person who gains admission to and completes refresher training through fraudulent representation of initial or previous refresher training documentation; or (d) Any person who obtains accreditation through fraudulent representation of accreditation requirements such as education, training, professional registration, or experience. H. Reciprocity EPA recommends that each State establish reciprocal arrangements with other States that have established accreditation programs that meet or exceed the requirements of the MAP. Such arrangements might address cooperation in licensing determinations, the review and approval of training programs and/or instructors, candidate testing and exam administration, curriculum development, policy formulation, compliance monitoring, and the exchange of information and data. The benefits to be derived from these arrangements include a potential cost-savings from the reduction of duplicative activity and the attainment of a more professional accredited workforce as States are able to refine and improve the effectiveness of their programs based upon the experience and methods of other States. II. EPA Approval Process for State Accreditation Programs A. States may seek approval for a single discipline or all disciplines as specified in the MAP. For example, a State that currently only requires worker accreditation may receive EPA approval for that discipline alone. EPA encourages States that currently do not have accreditation requirements for all disciplines required under section 206(b)(2) of TSCA, 15 U.S.C. 2646(b)(2), to seek EPA approval for those disciplines the State does accredit. As States establish accreditation requirements for the remaining disciplines, the requested information outlined below should be submitted to EPA as soon as possible. Any State that had an accreditation program approved by EPA under an earlier version of the MAP may follow the same procedures to obtain EPA approval of their accreditation program under this MAP. B. Partial approval of a State Program for the accreditation of one or more disciplines does not mean that the State is in full compliance with TSCA where the deadline for that State to have adopted a State Plan no less stringent than the MAP has already passed. State Programs which are at least as stringent as the MAP for one or more of the accredited disciplines may, however, accredit persons in those disciplines only. C. States seeking EPA approval or reapproval of accreditation programs shall submit the following information to the Regional Asbestos Coordinator at their EPA Regional office: 1. A copy of the legislation establishing or upgrading the State's accreditation program (if applicable). 2. A copy of the State's accreditation regulations or revised regulations. 3. A letter to the Regional Asbestos Coordinator that clearly indicates how the State meets the program requirements of this MAP. Addresses for each of the Regional Asbestos Coordinators are shown below: EPA, Region I, (ATC-111) Asbestos Coordinator, JFK Federal Bldg., Boston, MA 02203-2211, (617) 565-3836.

EPA, Region X, (AT-083), Asbestos Coordinator, 1200 Sixth Ave., Seattle, WA 98101, (206) 553-4762. EPA maintains a listing of all those States that have applied for and received EPA approval for having accreditation requirements that are at least as stringent as the MAP for one or more disciplines. Any training courses approved by an EPA-approved State Program are considered to be EPA-approved for purposes of accreditation. III. Approval of Training Courses Individuals or groups wishing to sponsor training courses for disciplines required to be accredited under section 206(b)(1)(A) of TSCA, 15 U.S.C. 2646(b)(1)(A), may apply for approval from States that have accreditation program requirements that are at least as stringent as this MAP. For a course to receive approval, it must meet the requirements for the course as outlined in this MAP, and any other requirements imposed by the State from which approval is being sought. Courses that have been approved by a State with an accreditation program at least as stringent as this MAP are approved under section 206(a) of TSCA, 15 U.S.C. 2646(a), for that particular State, and also for any other State that does not have an accreditation program as stringent as this MAP. A. Initial Training Course Approval A training provider must submit the following minimum information to a State as part of its application for the approval of each training course: 1. The course provider's name, address, and telephone number. 2. A list of any other States that currently approve the training course. 3. The course curriculum. 4. A letter from the provider of the training course that clearly indicates how the course meets the MAP requirements for: a. Length of training in days. b. Amount and type of hands-on training. c. Examination (length, format, and passing score). d. Topics covered in the course. 5. A copy of all course materials (student manuals, instructor notebooks, handouts, etc.). 6. A detailed statement about the development of the examination used in the course. 7. Names and qualifications of all course instructors. Instructors must have academic and/or field experience in asbestos abatement. 8. A description of and an example of the numbered certificates issued to students who attend the course and pass the examination. B. Refresher Training Course Approval The following minimum information is required for approval of refresher training courses by States: 1. The length of training in half-days or days. 2. The topics covered in the course. 3. A copy of all course materials (student manuals, instructor notebooks, handouts, etc.). 4. The names and qualifications of all course instructors. Instructors must have academic and/or field experience in asbestos abatement. 5. A description of and an example of the numbered certificates issued to students who complete the refresher course and pass the examination, if required. C. Withdrawal of Training Course Approval States must establish criteria and procedures for suspending or withdrawing approval from accredited training programs. States should follow their own administrative procedures in pursuing actions for suspension or withdrawal of approval of training programs. At a minimum, the criteria shall include: (1) Misrepresentation of the extent of a training course's approval by a State or EPA; (2) Failure to submit required information or notifications in a timely manner; (3) Failure to maintain requisite records; (4) Falsification of accreditation records, instructor qualifications, or other accreditation information; or (5) Failure to adhere to the training standards and requirements of the EPA MAP or State Accreditation Program, as appropriate. In addition to the criteria listed above, EPA may also suspend or withdraw a training course's approval where an approved training course instructor, or other person with supervisory authority over the delivery of training has been found in violation of other asbestos regulations administered by EPA. An administrative or judicial finding of violation, or execution of a consent agreement and order under 40 CFR 22.18, constitutes evidence of a failure to comply with relevant statutes or regulations. States may wish to adopt this criterion modified to include their own asbestos statutes or regulations. EPA may also suspend or withdraw approval of training programs where a training provider has submitted false information as a part of the self-certification required under Unit V.B. of the revised MAP. Training course providers shall permit representatives of EPA or the State which approved their training courses to attend, evaluate, and monitor any training course without charge. EPA or State compliance inspection staff are not required to give advance notice of their inspections. EPA may suspend or withdraw State or EPA approval of a training course based upon the criteria specified in this Unit III.C. IV. EPA Procedures for Suspension or Revocation of Accreditation or Training Course Approval A. If the Administrator decides to suspend or revoke the accreditation of any person or suspend or withdraw the approval of a training course, the Administrator will notify the affected entity of the following: 1. The grounds upon which the suspension, revocation, or withdrawal is based. 2. The time period during which the suspension, revocation, or withdrawal is effective, whether permanent or otherwise. 3. The conditions, if any, under which the affected entity may receive accreditation or approval in the future. 4. Any additional conditions which the Administrator may impose. 5. The opportunity to request a hearing prior to final Agency action to suspend or revoke accreditation or suspend or withdraw approval. B. If a hearing is requested by the accredited person or training course provider pursuant to the preceding paragraph, the Administrator will: 1. Notify the affected entity of those assertions of law and fact upon which the action to suspend, revoke, or withdraw is based. 2. Provide the affected entity an opportunity to offer written statements of facts, explanations, comments, and arguments relevant to the proposed action. 3. Provide the affected entity such other procedural opportunities as the Administrator may deem appropriate to ensure a fair and impartial hearing. 4. Appoint an EPA attorney as Presiding Officer to conduct the hearing. No person shall serve as Presiding Officer if he or she has had any prior connection with the specific case. C. The Presiding Officer appointed pursuant to the preceding paragraph shall: 1. Conduct a fair, orderly, and impartial hearing, without unnecessary delay. 2. Consider all relevant evidence, explanation, comment, and argument submitted pursuant to the preceding paragraph. 3. Promptly notify the affected entity of his or her decision and order. Such an order is a final Agency action. D. If the Administrator determines that the public health, interest, or welfare warrants immediate action to suspend the accreditation of any person or the approval of any training course provider, the Administrator will: 1. Notify the affected entity of the grounds upon which the emergency suspension is based; 2. Notify the affected entity of the time period during which the emergency suspension is effective. 3. Notify the affected entity of the Administrator's intent to suspend or revoke accreditation or suspend or withdraw training course approval, as appropriate, in accordance with Unit IV.A. above. If such suspension, revocation, or withdrawal notice has not previously been issued, it will be issued at the same time the emergency suspension notice is issued. E. Any notice, decision, or order issued by the Administrator under this section, and any documents filed by an accredited person or approved training course provider in a hearing under this section, shall be available to the public except as otherwise provided by section 14 of TSCA or by 40 CFR part 2. Any such hearing at which oral testimony is presented shall be open to the public, except that the Presiding Officer may exclude the public to the extent necessary to allow presentation of information which may be entitled to confidential treatment under section 14 of TSCA or 40 CFR part 2. V. Implementation Schedule The various requirements of this MAP become effective in accordance with the following schedules: A. Requirements applicable to State Programs 1. Each State shall adopt an accreditation plan that is at least as stringent as this MAP within 180 days after the commencement of the first regular session of the legislature of the State that is convened on or after April 4, 1994. 2. If a State has adopted an accreditation plan at least as stringent as this MAP as of April 4, 1994, the State may continue to: a. Conduct TSCA training pursuant to this MAP. b. Approve training course providers to conduct training and to issue accreditation that satisfies the requirements for TSCA accreditation under this MAP. c. Issue accreditation that satisfies the requirements for TSCA accreditation under this MAP. 3. A State that had complied with an earlier version of the MAP, but has not adopted an accreditation plan at least as stringent as this MAP by April 4, 1994, may: a. Conduct TSCA training which remains in compliance with the requirements of Unit V.B. of this MAP. After such training has been self-certified in accordance with Unit V.B. of this MAP, the State may issue accreditation that satisfies the requirement for TSCA accreditation under this MAP. b. Sustain its approval for any training course providers to conduct training and issue TSCA accreditation that the State had approved before April 4, 1994, and that remain in compliance with Unit V.B. of this MAP. c. Issue accreditation pursuant to an earlier version of the MAP that provisionally satisfies the requirement for TSCA accreditation until October 4, 1994. Such a State may not approve new TSCA training course providers to conduct training or to issue TSCA accreditation that satisfies the requirements of this MAP until the State adopts an accreditation plan that is at least as stringent as this MAP. 4. A State that had complied with an earlier version of the MAP, but fails to adopt a plan as stringent as this MAP by the deadline established in Unit V.A.1., is subject to the following after that deadline date: a. The State loses any status it may have held as an EPA-approved State for accreditation purposes under section 206 of TSCA, 15 U.S.C. 2646. b. All training course providers approved by the State lose State approval to conduct training and issue accreditation that satisfies the requirements for TSCA accreditation under this MAP. c. The State may not: i. Conduct training for accreditation purposes under section 206 of TSCA, 15 U.S.C. 2646. ii. Approve training course providers to conduct training or issue accreditation that satisfies the requirements for TSCA accreditation; or iii. Issue accreditation that satisfies the requirement for TSCA accreditation. EPA will extend EPA-approval to any training course provider that loses State approval because the State does not comply with the deadline, so long as the provider is in compliance with Unit V.B. of this MAP, and the provider is approved by a State that had complied with an earlier version of the MAP as of the day before the State loses its EPA approval. 5. A State that does not have an accreditation program that satisfies the requirements for TSCA accreditation under either an earlier version of the MAP or this MAP, may not: a. Conduct training for accreditation purposes under section 206 of TSCA, 15 U.S.C. 2646; b. Approve training course providers to conduct training or issue accreditation that satisfies the requirements for TSCA accreditation; or c. Issue accreditation that satisfies the requirement for TSCA accreditation. B. Requirements applicable to Training Courses and Providers As of October 4, 1994, an approved training provider must certify to EPA and to any State that has approved the provider for TSCA accreditation, that each of the provider's training courses complies with the requirements of this MAP. The written submission must document in specific detail the changes made to each training course in order to comply with the requirements of this MAP and clearly state that the provider is also in compliance with all other requirements of this MAP, including the new recordkeeping and certificate provisions. Each submission must include the following statement signed by an authorized representative of the training provider: "Under civil and criminal penalties of law for the making or submission of false or fraudulent statements or representations (18 U.S.C. 1001 and 15 U.S.C. 2615), I certify that the training described in this submission complies with all applicable requirements of Title II of TSCA, 40 CFR part 763, Appendix C to Subpart E, as revised, and any other applicable Federal, state or local requirements." A consolidated self-certification submission from each training provider that addresses all of its approved training courses is permissible and encouraged. The self-certification must be sent via registered mail, to EPA Headquarters at the following address: Attn. Self-Certification Program, Field Programs Branch, Chemical Management Division (7404), Office of Pollution Prevention and Toxics, Environmental Protection Agency, 401 M St., SW., Washington, DC 20460. A duplicate copy of the complete submission must also be sent to any States from which approval had been obtained. The timely receipt of a complete self-certification by EPA and all approving States shall have the effect of extending approval under this MAP to the training courses offered by the submitting provider. If a self-certification is not received by the approving government bodies on or before the due date, the affected training course is not approved under this MAP. Such training providers must then reapply for approval of these training courses pursuant to the procedures outlined in Unit III. C. Requirements applicable to Accredited Persons. Persons accredited by a State with an accreditation program no less stringent than an earlier version of the MAP or by an EPA-approved training provider as of April 3, 1994, are accredited in accordance with the requirements of this MAP, and are not required to retake initial training. They must continue to comply with the requirements for annual refresher training in Unit I.D. of the revised MAP. D. Requirements applicable to Non-Accredited Persons. In order to perform work requiring accreditation under TSCA Title II, persons who are not accredited by a State with an accreditation program no less stringent than an earlier version of the MAP or by an EPA-approved training provider as of April 3, 1994, must comply with the upgraded training requirements of this MAP by no later than October 4, 1994. Non-accredited persons may obtain initial accreditation on a provisional basis by successfully completing any of the training programs approved under an earlier version of the MAP, and thereby perform work during the first 6 months after this MAP takes effect. However, by October 4, 1994, these persons must have successfully completed an upgraded training program that fully complies with the requirements of this MAP in order to continue to perform work requiring accreditation under section 206 of TSCA, 15 U.S.C. 2646.

(5) An alien whose deportation is being withheld under Section 243(h) of the INA [8 U.S.C. section 1253(h)], as in effect immediately before the effective date of Section 307 of division C of Public Law 104-208), or Section 241(b)(3) of such Act [8 U.S.C. Section 1251(b)(3)], (as amended by Section 305(a) of division C of Public Law 104-208). (6) An alien who is granted conditional entry pursuant to Section 203(a)(7) of the INA as in effect prior to April 1, 1980. [8 U.S.C. s 1153(a)(7)] (See editorial note under 8 U.S.C. Section 1101, "Effective Date of 1980 Amendment.") (7) An alien who is a Cuban or Haitian entrant (as defined in Section 501(e) of the Refugee Education Assistance Act of 1980 [8 U.S.C. s 1522 note)].

For purposes of this subsection, the term "battered or subjected to extreme cruelty" includes, but is not limited to being the victim of any act or threatened act of violence including any forceful detention, which results or threatens to result in physical or mental injury. Rape, molestation, incest (if the victim is a minor), or forced prostitution shall be considered to be acts of violence. (B) There is a substantial connection between such battery or cruelty and the need for the benefits to be provided in the opinion of Division. For purposes of this subsection, the following circumstances demonstrate a substantial connection between the battery or cruelty and the need for the benefits to be provided: 1. The benefits are needed to enable the alien to become self-sufficient following separation from the abuser. 2. The benefits are needed to enable the alien to escape the abuser and/or the community in which the abuser lives, or to ensure the safety of the alien from the abuser. 3. The benefits are needed due to a loss of financial support resulting from the alien's separation from the abuser. 4. The benefits are needed because the battery or cruelty, separation from the abuser, or work absences or lower job performance resulting from the battery or extreme cruelty or from legal proceedings relating thereto (including resulting child support, child custody, and divorce actions), cause the alien to lose his or her job or to earn less or to require the alien to leave his or her job for safety reasons. 5. The benefits are needed because the alien requires medical attention or mental health counseling, or has become disabled, as a result of the battery or extreme cruelty. 6. The benefits are needed because the loss of a dwelling or source of income or fear of the abuser following separation from the abuser jeopardizes the alien's ability to care for his or her children (e.g., inability to house, feed, or clothe children or to put children into day care for fear of being found by the abuser). 7. The benefits are needed to alleviate nutritional risk or need resulting from the abuse or following separation from the abuser. 8. The benefits are needed to provide medical care during a pregnancy resulting from the abuser's sexual assault or abuse of, or relationship with, the alien and/or to care for any resulting children. 9. Where medical coverage and/or health care services are needed to replace medical coverage or health care services the alien had when living with the abuser. (C) The alien has a petition that has been approved or has a petition pending which sets forth a prima facie case for: 1. Status as a spouse or child of a United States citizen pursuant to clause (ii), (iii), or (iv) of Section 204(a)(1)(A) of the INA [8 U.S.C. section 1154(a)(1)(A)(ii), (iii) or (iv)]. 2.

Section 1229b) as in effect prior to April 1, 1997"). 4. Status as a spouse or child of a United States citizen pursuant to clause (i) of Section 204(a)(1)(A) of the INA [8 U.S.C. section 1154(a)(1)(A)] or classification pursuant to clause (i) of Section 204(a)(1)(B) of the INA [8 U.S.C. section 1154(a)(1)(B)(i)]. 5. Cancellation of removal pursuant to Section 240A(b)(2) of the INA (8 U.S.C. Section 1229(b)(2)). (D) For the period for which benefits are sought, the individual responsible for the battery or cruelty does not reside in the same household or family eligibility unit as the individual subjected to the battery or cruelty. (9) An alien who meets all of the conditions of subparagraphs (A), (B), (C), (D) and (E) below: (A) The alien has a child who has been battered or subjected to extreme cruelty in the United States by a spouse or a parent of the alien (without the active participation of the alien in the battery or cruelty), or by a member of the spouse's or parent's family residing in the same household as the alien, and the spouse or parent consented or acquiesced to such battery or cruelty. For purposes of this subsection, the term "battered or subjected to extreme cruelty" includes, but is not limited to being the victim of any act or threatened act of violence including any forceful detention, which results or threatens to result in physical or mental injury. Rape, molestation, incest (if the victim is a minor), or forced prostitution shall be considered as acts of violence. (B) The alien did not actively participate in such battery or cruelty.

The benefits are needed to enable the alien's child to become self-sufficient following separation from the abuser. 2. The benefits are needed to enable the alien's child to escape the abuser and/or the community in which the abuser lives, or to ensure the safety of the alien's child from the abuser. 3. The benefits are needed due to a loss of financial support resulting from the alien's child's separation from the abuser. 4.

The benefits are needed because the alien's child requires medical attention or mental health counseling, or has become disabled, as a result of the battery or extreme cruelty. 6. The benefits are needed because the loss of a dwelling or source of income or fear of the abuser following separation from the abuser jeopardizes the alien's child's ability to care for his or her children (e.g., inability to house, feed, or clothe children or to put children into day care for fear of being found by the abuser). 7. The benefits are needed to alleviate nutritional risk or need resulting from the abuse or following separation from the abuser. 8. The benefits are needed to provide medical care during a pregnancy resulting from the abuser's sexual assault or abuse of, or relationship with, the alien's child and/or to care for any resulting children. 9. Where medical coverage and/or health care services are needed to replace medical coverage or health care services the alien's child had when living with the abuser. (D) The alien meets the requirements of subsection (c)(8)(C) above.

(c) The alien child meets the requirements of Subsection (c)(8)(C). (d) For purposes of this section, "nonimmigrant" is defined the same as in Section 101(a)(15) of the INA [8 U.S.C. section 1101(a)(15)]. (e) For purposes of establishing eligibility for benefits, as described in subsection (b)(1)-(b)(6), all of the following must be met: (1) The applicant shall declare himself or herself to be a citizen of the United States or a qualified alien under subsection (c), a nonimmigrant alien under subsection (d), or an alien paroled into the United States for less than one year under Section 212(d)(5) of the INA [8 U.S.C. section 1182(d)(5)]. The applicant shall declare that status through use of the "Statement of Citizenship, Alienage, and Immigration Status for State Public Benefits," Cal/OSHA-W-1 issued on April 30, 1998, incorporated herein by reference. (2) The applicant shall present documents of a type acceptable to the Immigration and Naturalization Service (INS) which serve as reasonable evidence of the applicant's declared status. (3) The applicant shall complete and sign a Cal/OSHA-W-1 issued on April 30, 1998, incorporated herein by reference. (4) Where authorized by the INS, the documentation presented by an alien as reasonable evidence of the alien's declared immigration status must be submitted to the INS for verification through the Systematic Alien Verification for Entitlements (SAVE) system procedures as follows: (A) Unless the primary SAVE system is unavailable for use, the primary SAVE system verification shall be used to access the biographical/immigration status computer record contained in the Alien Status Verification Index maintained by the INS. Except as provided in the next paragraph [(subparagraph (B)], this procedure shall be used to verify the status of all aliens who claim to be qualified aliens and who present an INS-issued document that contains an alien registration or alien admission number. (B) In any of the following cases, the secondary SAVE system verification procedure shall be used to forward copies of original INS documents evidencing an alien's status as a qualified alien, as a nonimmigrant alien under the INA, or as an alien paroled into the United States under Section 212(d)(5) of the INS [8 U.S.C. section 1182(d)(5)], for less than one year: 1. The primary SAVE system is unavailable for verification. 2. A primary check of the Alien Status Verification Index instructs the Division to institute secondary verification. 3. The document presented indicates immigration status but does not include an alien registration or alien admission number. 4. The Alien Status Verification Index record includes the alien registration or admission number on the document presented by the alien but does not match other information contained in the document. 5. The document is suspected to be counterfeit or to have been altered. 6. The document includes an alien registration number in the "not yet issued" or "illegal border crossing" series, as defined by the INS. Note: The numbers used by the INS for each series are A60 000 000 and A80 000 000 respectively, as of the date of adoption of this regulation. 7. The document is a fee receipt from INS for replacement of a lost, stolen, or unreadable INS document. 8. The document is one of the following: an INS Form I-181b notification letter issued in connection with an INS Form I-181 Memorandum of Creation of Record of Permanent Residence; an Arrival-Departure Record (INS Form I-94); or a foreign passport stamped "PROCESSED FOR I-551, TEMPORARY EVIDENCE OF LAWFUL PERMANENT RESIDENCE" that INS issued more than one year before the date of application for a benefit described in subsection (b)(1)-(b)(6). (5) Where verification through the SAVE system is not available, if the documents presented do not on their face reasonably appear to be genuine or to relate to the individual presenting them, the government entity that originally issued the document shall be contacted for verification. With regard to naturalized citizens and derivative citizens presenting certificates of citizenship and aliens, the INS is the appropriate government entity to contact for verification. The Division shall request verification by the INS by filing INS Form G-845 with copies of the pertinent documents provided by the applicant with the local INS office. If the applicant has lost his or her original documents, or presents expired documents or is unable to present any documentation evidencing his or her immigration status, the applicant should be referred to the local INS office to obtain documentation. (6) If the INS advises that the applicant has citizenship status or immigration status which makes him or her a qualified alien, a nonimmigrant or alien paroled for less than one year under section 212(d)(5) of the INA, the INS verification shall be accepted. If the INS advises that it cannot verify that the applicant has citizenship status or an immigration status that makes him or her a qualified alien, or a nonimmigrant or an alien paroled for less than one year under section 212(d)(5) of the INA, benefits shall be denied and the applicant notified pursuant to subsection (h) or (i) of his or her rights to appeal the denial of benefits. (7) Provided that the alien has completed and signed form Cal/OSHA-W-1 issued on April 30, 1998, incorporated herein by reference, under penalty of perjury, eligibility for benefits for certification, license or registration, as found in subsection (b)(1)-(b)(6), shall not be delayed, denied, reduced or terminated while the status of the alien is verified. (f) Pursuant to Section 432(d) of the PRWORA (8 U.S.C. section 1642(d)), a nonprofit charitable organization that provides federal, state, or local public benefits shall not be required to determine, verify, or otherwise require proof of eligibility of any applicant or beneficiary with respect to his or her immigration status or alienage. (g) Pursuant to Section 434 of the PRWORA (8 U.S.C. section 1644), where the Division reasonably believes that an alien is unlawfully in the State based on the failure of the alien to provide reasonable evidence of the alien's declared status, after an opportunity to do so, said alien shall be reported to the Immigration and Naturalization Service. (h) Denial of Application. (1) The Division shall deny issuance of the benefit applied for if the applicant does not meet the requirements of this section. Upon denial of the benefit the Division shall promptly notify the applicant specifying the reason for the denial. (2) Any applicant denied certification, license or registration by the Division may appeal such denial to the Director. The Director shall hold a hearing at such place designated by the Director or his authorized designee for the convenience of the applicant within two working days of the applicant's appeal. The hearing shall be presided by the Director or his authorized designee. (3) Following the hearing, the Director shall issue a decision. The Director's decision shall be final except for any rehearing or judicial review provided for by law. All requests for rehearing shall be filed with the Director within 10 days from the date of the Director's decision. (i) Revocation or Suspension of Certification, License or Registration. (1) The Division may at any time, upon a showing of good cause and after notice and an opportunity to be heard, revoke or suspend any benefit issued pursuant to this section. (2) Notice shall be in writing and served upon the recipient of the benefit at least 24 hours in advance of the hearing. Service shall be by personal service or certified mail to the recipient of the benefit to the address as shown on the application form. The notice shall specify the reasons for the action taken by the Division in order that the recipient may prepare for the hearing. The Division shall also include within the notice of revocation or suspension specific conditions which must be met before the recipient of the benefit will be entitled to reapply for the benefit of this section. (3) The hearing shall be held as soon as possible at the Division's headquarters offices or at such other location as may be designated by the Director and shall be presided by the Chief of the Division or his authorized representative. (4) At the hearing the Division shall establish good cause for the action taken by it. Good cause is deemed to exist if the Division establishes that the recipient of the benefit has failed to comply with the requirements of this section. The recipient of the benefit may appeal such revocation or suspension to the Director in the same manner specified in subsection (h). The filing of an appeal shall not stay the revocation or suspension, and such action shall remain in effect until the benefit recipient provides proof that the requirements of this section have been met.

Impalement Protection. Specifications and Testing Criteria (See Construction Safety Orders, Title 8, CCR s 1712). (a) Scope: This section governs the testing of manufactured protective covers designed to prevent accidental impalement from exposed reinforcing steel (rebar) or other similar projections. (b) Effective Date: This section applies to all protective covers manufactured on or after October 1, 2000. (c) All manufactured protective covers used as protection against impalement for workers at grade or the same level as the projection shall: (1) Pass the drop test described in subsection (e) of this section, except that the drop height may be reduced to 7 1/2 ' . (2) Meet all other applicable requirements of section 1712 of this Code. (d) All manufactured protective covers used as protection against impalement for work performed at levels not to exceed 7 1/2 ' above grade shall: (1) Have a minimum of 4 " by 4 " square surface area, or if round, a minimum diameter of 4 1/2 " . Troughs shall be at least 4 " wide. (2) Pass the drop test specified in subsection (e) of this section. (3) Meet all other applicable requirements of section 1712 of this Code. (e) Manufactured protective covers shall be able to pass the following penetration tests, as verified by a person, firm, or entity with appropriate registered-engineering competence, or by a person, firm, or entity, independent of the manufacturer of the subject protective covers, with demonstrated competence in the field of such evaluation. (1) Protective covers for rebar shall be tested for penetration by dropping a 250-lb. bag of dry sand (less than 10% moisture by weight) onto the subject protective cover from a height of 10 ' . The 10 ' shall be measured from the bottom of the bag to the top of the protective cover. (A) The sandbag shall be generally round, and shall have a circumference of 36 " to 42 " . When filled with 250 lbs. of sand, the bag shall be tightly closed by use of crimping, drawstring, or twisting at the top level of the sand so that there is little extra room in the bag to allow the sand to shift. The bag shall be constructed and reinforced (as necessary) with material, which will not rupture or be penetrated by the protective cover for rebar. (B) The protective cover for rebar shall be installed over the sheared end of a piece of #4 rebar. The rebar shall be mounted on a support with 6 " of the rebar projecting vertically above the surface of the support. The support shall be of such height and width that it shall not interfere with the falling sandbag, and shall allow the full initial impact of the sandbag to be borne by the protective cover. (C) The drop test shall be repeated three times, using a new protective cover for each test. One drop test shall be performed with the protective cover sitting squarely on top of the rebar; the other two drop tests shall be performed with the protective cover sitting at the maximum angle out of square (out of level) that the protective cover will permit with its stabilizer vanes/fins removed. (2) Protective covers for projections or equipment other than rebar, (such as lighting rods,) shall be tested in the same manner as protective covers for rebar, except that protruding equipment which is normally installed with a protective cover as a single unit may be tested as a unit, using the equipment in lieu of the rebar. (3) Rebar troughs shall be tested for penetration by dropping a 250-lb bag of dry sand (less than 10% moisture by weight) onto the subject trough from a height of 10 ' . The 10 ' shall be measured from the bottom of the bag to the top of the protective cover. (A) The sandbag shall be generally round, and shall have a circumference of 36 " to 42 " . When filled with 250 lbs. of sand, the bag shall be tightly closed by use of crimping, drawstring, or twisting at the top level of the sand so that there is little extra room in the bag to allow the sand to shift. The bag shall be constructed and reinforced (as necessary) with material, which will not rupture or be penetrated by the protective cover for rebar. (B) The trough shall be installed over the sheared ends of three pieces of #4 rebar. The three pieces rebar shall be mounted in a straight line, 24 " apart, on a support with 6 " of each piece of rebar projecting vertically above the surface of the support. The trough shall be 72 " in length, and shall be centered over the three pieces of rebar so that 12 " of the trough extends beyond each of the outside pieces of rebar. (C) The drop test shall be repeated four times, using a new trough for each test. The sandbag shall be dropped: (i) once with the trough level and the sandbag centered over the middle piece of rebar; (ii) once with the trough level and the sandbag centered over one of the end pieces of rebar; (iii) once with the trough tilted (at the maximum angle allowed by the design) with the sandbag centered over the middle piece of rebar; (iv) once with the trough tilted (at the maximum angle allowed by the design) with the sandbag centered over one of the end pieces of rebar. (4) Other methods for penetration testing may be substituted for those set forth in this section where acceptable to the Division as being equally effective. (f) Each manufacturer, or other person or entity reselling or distributing manufactured protective covers, shall furnish the ultimate user of the protective cover with instructions regarding appropriate use of the protective covers. The instructions, written in English, shall include at least the following: (1) Instructions as to whether the protective cover is designed for use at grade or above grade. (2) A statement indicating the maximum height of fall that the cover is designed to protect against impalement, but not to exceed 7 1/2 ' . (3) Installation instructions. (4) Instructions regarding the inspection and/or use of damaged or defective protective covers. The effects, if any, of damaged stabilizer vanes/fins shall be included in this instruction. (5) Any other instructions deemed necessary by the manufacturer regarding the use of the protective covers. (g) Each employer whose employees use or work around or above protective covers shall inform its employees of the content of the manufacturer's instructions. Such information shall be provided to employees in a manner that allows them to understand the appropriate use of protective covers and the hazards associated with impalement. (h) Marking -Each protective cover shall be marked with the following information: (1) Model Number or Trademark. (2) California Approval Number as issued pursuant to Sections 1712 and 1505 of this Code. (3) Size(s) designation. Note: Authority cited: Sections 60.5 and 6308, Labor Code.

Subpoena and Subpoena Duces Tecum. (a) Before the hearing has commenced, the Appeals Board shall issue a subpoena and subpoena duces tecum at the request of a party for attendance of a person at a hearing and for production of a document or thing at the hearing or prehearing conference or at any reasonable time and place. After the hearing has commenced, the Appeals Board may, upon a showing of good cause by the requesting party, issue a subpoena or subpoena duces tecum. (b) Application for a subpoena duces tecum requires: (1) Compliance with the provisions of Section 1985 to 1985.4, inclusive, of the Code of Civil Procedure as a condition precedent to the issuance of a subpoena duces tecum; and that (2) The application for a subpoena duces tecum shall be in the form of an affidavit or declaration under penalty of perjury and shall show good cause for the production of the document or thing requested, specifying the exact document or thing desired to be produced, setting forth in full detail the materiality thereof to the issues involved in the proceeding, and stating that the witness has the desired document or thing in the possession or control of the witness. The application shall also state that if the personal attendance of the witness or other qualified custodian of the records is not required, compliance pursuant to Article 4 (commencing with Section 1560) of the Evidence Code will be permitted. (c) Any subpoena or subpoena duces tecum issued pursuant to subdivision (a) extends to all parts of the State. The provisions of Sections 1987 and 1988 of the Code of Civil Procedure are applicable to the service of a subpoena or a subpoena duces tecum. Service must be made so as to allow the witness a reasonable time for preparation and travel to the place of attendance. Service of a subpoena or subpoena duces tecum is made by delivering a copy to the witness together with a copy of the affidavit or declaration upon which the subpoena duces tecum is based, giving or offering at the same time, if demanded, the fees to which the witness is entitled for travel to and from the place designated. See Section 382 for amount of witness fees and mileage. Service shall be made by personal delivery or by certified mail return receipt requested or by messenger. (1) Service by personal delivery may be made by any person. (2) Service by messenger shall be effected when the witness acknowledges receipt of the subpoena to the sender, by telephone, by mail, or in person, and identifies himself or herself either by reference to date of birth and driver's license number or Department of Motor Vehicles identification number, or the sender may verify receipt of the subpoena by obtaining other identifying information from the recipient. The sender shall make a written notation of the acknowledgment. A subpoena issued and acknowledged pursuant to this section has the same force and effect as a subpoena personally served. Failure to comply with a subpoena issued and acknowledged pursuant to this section may be punished as a contempt and the subpoena may so state. (d) All witnesses appearing pursuant to subpoena, other than the parties or officers or employees of the State or any political subdivision thereof, shall receive fees, and all witnesses appearing pursuant to subpoena, except the parties, shall receive mileage in the same amount and under the same circumstances as prescribed by law for witnesses in civil actions in a superior court. Fees and mileage shall be paid by the party at whose request the witness is subpoenaed. See Section 382 for amount of witness fees and mileage. All reasonable costs, as defined at Section 1563(b)(1) of the Evidence Code, incurred by a witness not a party, with respect to the production of a business record pursuant to a subpoena duces tecum, shall be paid to the witness before being required to deliver the document. (e) No witness shall be obligated to attend unless the witness is a resident of the state at the time of service. (f) Upon timely motion of a party or witness, or upon its own motion, after notice to the parties and an opportunity to be heard, upon a showing of good cause, the Appeals Board may order the quashing of a subpoena or subpoena duces tecum entirely, may modify it, or may direct compliance with it upon other terms or conditions. In addition, the Appeals Board may make any other order as may be appropriate to protect a party or witness from unreasonable or oppressive demands.

At the request of a party, the Appeals Board may issue a subpoena re deposition and subpoena duces tecum re deposition to compel the person to appear for deposition, and to produce books, documents, or other things. Compliance with the provisions of Section 1985 of the Code of Civil Procedure shall be a condition precedent to the issuance of a subpoena duces tecum re deposition. (b) When a person resides outside the state, the Appeals Board, if requested by a party to the proceeding, shall attempt, when possible, to have a like agency in the other state take the deposition. (c) A person who is subpoenaed and required to give a deposition is entitled to receive the same witness fees and mileage as if the subpoena required the person to attend and testify at the hearing. See Section 382 for amount of witness fees and mileage. (d) No person is obligated to attend at a place out of the county of residence unless the distance is less than 75 miles from the place of residence except that the Appeals Board, upon affidavit or declaration of a party showing good cause, may endorse on the subpoena re deposition an order requiring the attendance of such person. (e) Depositions shall be noticed, taken, filed, and used in the manner prescribed by Article 3 (commencing with Section 2016) of Chapter 3 of Title 3 of Part 4 of the Code of Civil Procedure. (f) Upon timely motion of a party or the person to be examined or notified to produce books, documents, or other things, or upon its own motion, after notice to the parties and an opportunity to be heard, upon a showing of good cause, the Appeals Board may order that the deposition not be taken, or that it may be taken only at some designated time or place other than stated in the notice of taking deposition or subpoena, or that the deposition may be taken outside the county of residence of the person to be examined and at a place more than 150 miles from the place of residence, or that certain matters shall not be inquired into, or that the scope of the examination shall be limited to certain matters, books, documents, or other things, or that the confidentiality of evidence described at Section 376.6(a) be appropriately protected.

Evidence by Affidavit or Declaration. (a) At any time 10 or more days prior to a hearing or a continued hearing, a party may mail or deliver to the opposing party or parties a copy of any affidavit or declaration which the proponent proposes to introduce in evidence, together with a notice as provided in subdivision (b). Unless an opposing party, within 7 days after such mailing or delivery, mails or delivers to the proponent a request to cross-examine the affiant or declarant, the opposing party's right to cross-examine such affiant or declarant is waived and the affidavit or declaration, if introduced in evidence, shall be given the same effect as if the affiant or declarant had testified orally. If an opportunity to cross-examine an affiant or declarant is not afforded after request therefor is made as herein provided, the affidavit or declaration may be introduced in evidence, but shall be given only the same effect as other hearsay evidence. (b) The notice referred to in subdivision (a) shall be substantially in the following form: "The accompanying affidavit or declaration of (here insert name of affiant or declarant) will be introduced as evidence at the hearing in (here insert title and docket number or petition number of proceeding). (Here insert name) will not be called to testify orally and you will not be entitled to question the affiant or declarant unless you notify (name of the proponent, representative, agent or attorney) at (here insert address) that you wish to cross-examine the affiant or declarant. To be effective, your request must be mailed or delivered to (here insert name of proponent, representative, agent or attorney) on or before (here insert a date 7 days after the date of mailing or delivering the affidavit to the opposing party)."

(a) If any witness refuses to attend or testify or produce any papers required by a subpoena issued by the Appeals Board, a party may file with the Appeals Board a petition for judicial enforcement. The petition shall be verified and shall set forth that due notice of the time and place of attendance of the person or the production of the papers has been given, that the person has been subpoenaed in the manner prescribed by law and these rules, and that the person has failed and refused to attend or produce the papers required by the subpoena in the cause or proceeding named in the subpoena, or has refused to answer the questions propounded in the course of the hearing or deposition. (b) If the Appeals Board determines that judicial enforcement is appropriate, it will petition the superior court in the county in which the hearing is pending for an order compelling the person to attend and testify or produce the papers pursuant to Government Code Sections 11186 through 11188, inclusive. Note: Authority cited: Sections 148.7 and 149.5, Labor Code. Reference: Sections 11186-11188, 11455.10 and 11455.20, Government Code; and Sections 148.7, 148.8, 149.5 and 6603, Labor Code. s 372.6. Proceeding to Compel Discovery. (a) A party claiming that its request for discovery pursuant to Sections 372 and 372.1 has not been complied with may serve and file with the Administrative Law Judge or the Appeals Board, if the Appeals Board is hearing the case, a motion to compel discovery naming as respondent the party refusing to comply. The motion shall comply with Section 11507.7 of the Government Code and shall state: (1) Facts showing that respondent refused or failed to comply with Section 372 or Section 372.1; (2) A description of the matters sought to be discovered; (3) The reason or reasons why such matter is discoverable under these rules; and (4) A reasonable and good faith attempt to contact the respondent for an informal resolution of the issue has been made; and (5) The ground or grounds of respondent's refusal so far as known. (b) The motion to compel discovery shall be served upon respondent and filed within 15 days after respondent first evidenced a refusal or failure to comply with Sections 372 and 372.1, or within 30 days after the discovery request was made and respondent has failed to reply to the request, or within another time stipulated by the parties with the approval of the Administrative Law Judge or the Appeals Board, whichever period is longer. The motion shall comply with Section 371(a) and (b). (c) The hearing on the motion to compel discovery shall be held within 15 days after the motion is made, or a later time that the Administrative Law Judge or the Appeals Board may, on its own motion for good cause determine. Respondent shall have the right to serve and file a written answer or other response to the motion before or at the time of hearing. The answer must comply with Section 371(a) and (b).

The parties may stipulate, with the approval of the Administrative Law Judge or the Appeals Board, to waive a hearing on the motion to compel discovery, provided that the stipulation provides a date by which respondent shall file its response and requires that the order on the motion shall issue within 30 days of the date the motion was filed. (d) Where the matter sought to be discovered is under the custody or control of respondent and respondent asserts that the matter is not a discoverable matter under the provisions of Section 372.1(a) through (d), or is privileged against disclosure under (f), the Administrative Law Judge or the Appeals Board may order that the matter be lodged with it and examined in accordance with the provisions of Subdivision (b) of Section 915 of the Evidence Code. The Administrative Law Judge or the Appeals Board shall decide the motion based upon the matters examined in camera, the papers filed by the parties, and such oral argument and additional evidence as the Administrative Law Judge or the Appeals Board may allow. (e) Unless otherwise stipulated by the parties with the approval of the Administrative Law Judge or the Appeals Board, the Administrative Law Judge or the Appeals Board shall, no later than 15 days after the hearing, issue a written order denying or granting the motion. The Administrative Law Judge or the Appeals Board shall promptly serve a copy of the order to each party or representative. Where the order grants the motion, in whole or in part, the order shall set forth the matters the moving party is entitled to discover under Sections 372 and 372.1. The order shall not become effective until 10 days after the date the order is served. Where the order denies the motion in its entirety, the order shall be effective on the date it is served.

Reference: Section 148.7, Labor Code. s 373. Expedited Proceeding. Upon motion of a party or upon its own motion, the Appeals Board may order an expedited proceeding. All parties shall be notified and shall be expected to do all things necessary to complete the proceeding in the minimum time consistent with fairness. Time limits for filing a motion to compel discovery, and for responsive filings under Section 372.6 may be shortened as necessary to accommodate the expedited date for disposition of the case.

The prehearing conference may be conducted by means of a telephone conference call. (b) Each party to a prehearing conference shall be prepared to discuss the issues, stipulate to any factual or legal issue about which there is no dispute, stipulate to the identification and admissibility of documentary evidence, comply with any request for discovery, and to do such other things as may aid in the disposition of the proceeding. (c) The failure of a party or its representative to prepare for and participate in the prehearing conference shall be grounds for the imposition of such sanctions, inferences or other orders, then or during the hearing, as the Appeals Board may deem appropriate. These sanctions may include striking or excluding evidence offered by the non-complying party on that dispute, or precluding that party from contesting the position or information on that issue provided by the complying party.

The hearing de novo may be waived if all parties stipulate that the newly assigned Administrative Law Judge may review the hearing record and all of the evidence received, and that the hearing may proceed as if he had presided from the beginning.

Reference: Section 641, Code of Civil Procedure; and Sections 148.7, 149.5, and 6606, Labor Code. s 376. Time and Place of Hearing. (a) Appeals shall be heard promptly. (b) Appeals relating to a special order, order to take special action, the reasonableness of the abatement period and an expedited proceeding shall be given priority over other proceedings. (c) In cases being reviewed by the Bureau of Investigations, unless the employer submits a written request that its appeal go forward in the normal course, the Appeals Board shall delay the hearing until the conclusion of a review of the case by the Bureau of Investigations or for a period not exceeding 2 years, whichever occurs earlier. The period may be extended beyond 2 years at a party's request if necessary to allow the Bureau of Investigations to conclude its review of the case.

(a) Testimony shall be taken only on oath, affirmation, or penalty of perjury. (b) Each party shall have these rights: To call and examine witnesses; to introduce exhibits; to question opposing witnesses on any matter relevant to the issues even though that matter was not covered in the direct examinations; to impeach any witness regardless of which party first called the witness to testify; and to rebut any opposing evidence. If a party does not testify on his or her behalf, the party may be called and examined as if under cross-examination. (c) The Appeals Board may call and examine a party or witness and may, on its own motion, admit any relevant and material evidence. (d) The taking of evidence in a hearing shall be controlled by the Appeals Board in the manner best suited to ascertain the facts and safeguard the rights of the parties. Prior to taking evidence, the Appeals Board shall define the issues and explain the order in which evidence will be received. (e) Once a hearing has commenced and until a decision is issued, all motions or questions regarding the proceeding shall be referred to the assigned administrative law judge. If written, the motion shall be served in a manner as prescribed in Section 355(c) and proof of service meeting the requirements of Section 355(e) shall be filed with the Appeals Board. An opposing party may respond in the manner and within such time as the administrative law judge may direct. (f) Continuance requests shall be entertained at the hearing only in cases of: (1) unforeseen emergencies, including, but not limited to, death or illness of a party, witness, or representative, or (2) non-appearance of a subpoenaed witness whose testimony is material to the outcome of the proceeding.

The hearing need not be conducted according to technical rules relating to evidence and witnesses. Any relevant evidence shall be admitted if it is the sort of evidence on which responsible persons are accustomed to rely in the conduct of serious affairs, regardless of the existence of any common law or statutory rule which might make improper the admission of such evidence over objection in civil actions. Hearsay evidence may be used for the purpose of supplementing or explaining other evidence but over timely objection shall not be sufficient in itself to support a finding unless it would be admissible over objection in civil actions. An objection to hearsay evidence is timely if made before submission of the case or raised in a petition for reconsideration. The rules of privilege shall be effective to the extent that they are otherwise required by statute to be recognized at the hearing and irrelevant evidence shall be excluded. The Appeals Board may exclude evidence if its probative value is substantially outweighed by the probability that its admission will necessitate undue consumption of time.

A request for an interpreter shall be made to the Appeals Board no later than 10 working days prior to the date the interpreter is needed. The cost of providing the interpreter for a party shall be paid by the party requesting the interpreter unless the Appeals Board directs that the Appeals Board shall pay the cost of providing the interpreter due to financial hardship of the requesting party. (c) If a party's witness does not proficiently speak or understand the English language, the terms and conditions set forth in subsection (b) shall apply. The party presenting the witness may request the Appeals Board to provide an interpreter under those terms and conditions.

(g) Before appointment of an interpreter, the Appeals Board or a party may conduct a brief supplemental examination of the prospective interpreter to see if the person has the qualifications necessary to serve as an interpreter in the hearing or prehearing conference and to see if the person understands terms and procedures generally used in hearings and prehearing conferences before the Appeals Board, can explain these terms and procedures in English and the other language being used, and can interpret these terms and procedures into the other language. An interpreter shall not have had any involvement in the issues of the proceeding prior to the hearing or prehearing conference, and shall disclose to the Appeals Board and to all parties any actual or apparent conflict of interest. Any condition that interferes with the objectivity of an interpreter constitutes a conflict of interest. A conflict may exist if an interpreter is acquainted with or related to a party or witness to the proceeding or if an interpreter has an interest in the outcome of the proceeding. (h) The Appeals Board shall disqualify an interpreter if the interpreter cannot understand and interpret the terms and procedures used in the hearing or prehearing conference, has engaged in conduct creating the appearance of bias, prejudice, or partiality, or has disclosed privileged or confidential communications.

Reference: Section 149.5, Labor Code. s 396. Definitions. As used in Sections 395 to 397, inclusive, of these rules: (a) "Burden of proof" means the burden on an employer petitioning for costs to establish by a preponderance of the evidence that the issuance of a citation was the result of arbitrary or capricious action or conduct by the Division. (b) "Citation is withdrawn" means that after an employer has filed an appeal in accord with Section 359, and the Appeals Board has acknowledged jurisdiction, that the Appeals Board grants the Division's motion or petition to withdraw the citation. (c) "Final decision" means a decision or order of the Appeals Board or an Administrative Law Judge which has not been stayed or from which no petition for reconsideration has been filed or no reconsideration has been granted on the Appeals Board's own motion within the time permitted by law. If the Appeals Board has granted reconsideration, a decision or order shall be final 30 days after the decision after reconsideration has been issued unless a writ of mandate has been filed as provided by law. If a writ of mandate has been filed, a decision or order shall be final after a judgment has been entered and no appeal is pending in the courts. (d) "Prevails in the appeal" occurs when an employer has prevailed in the appeal on an item of a citation or a total citation. An employer who appeals the existence of a violation shall not be deemed to have prevailed in the appeal if the alleged violation is affirmed and the Appeals Board only amends the classification of the violation or reduces the amount of proposed civil penalty. (e) "Reasonable costs" means costs necessarily incurred by an employer in preparing for and pursuing an appeal of a citation. Reasonable costs are those costs allowed under Section 149.5 of the Labor Code, including attorney's fees, consultant's fees, witness' fees and mileage, costs of discovery, costs of depositions, and costs of service of process if such costs were necessary disbursements for preparing and proceeding with a hearing on the citation.

The burden of proof shall be on the employer to establish by a preponderance of the evidence that the issuance of the citation was the result of arbitrary or capricious action or conduct by the Division. (b) The procedures are: (1) If an employer who appeals a citation prevails in the appeal of the citation or the citation is withdrawn and the employer wishes to claim reimbursement for reasonable costs alleging that the issuance of the citation was the result of arbitrary or capricious action or conduct by the Division, the employer shall file a petition for costs together with a memorandum of items of cost with the Appeals Board.

Petitions for reconsideration and answers, if any, shall be in conformity with Article 5 of these rules, or (B) The petition for costs may be granted by a cost order and costs may be awarded if from a review of the petition for costs and the response submitted, if any, it is established that the Division issued a citation as the result of arbitrary or capricious action or conduct. The Division and the employer shall have the right to file a petition for reconsideration of the cost order granting the petition for costs within 30 days after service of such an order. Petitions for reconsideration and answers, if any, shall be in conformity with Article 5 of these rules, or (C) If a review of the petition for costs and response, if any, establishes that a factual dispute exists, the matter shall be set for hearing. Parties shall receive not less than 15 days notice of hearing.

Ten calendar days before the time of hearing, an employer may file with the Appeals Board and the Division a supplemental memorandum of costs setting forth necessary disbursements claimed. When a party desires to present any point which requires a consideration of a prior hearing record, the party shall, prior to the hearing, request and pay the cost of preparing the prior hearing record.

(4) The use of expansion plugs or serrated plugs without through stays is limited to 6 " nominal pipe size and/or 150 psi; for use of such devices above these limits specific written test procedures must be developed by the employer to protect against injury in the event the plug blows out. Such instructions may include applicable data and recommendations furnished by the plug manufacturer and must include the following as a minimum: (A) Identification by function of the personnel responsible for the various procedures. (B) The test plugs must be well maintained and inspected by the designated employee before use. (C) Any opening to be plugged shall satisfy any limitation on straightness, roundness and diameter and shall be cleaned of dirt, mill scale or oil. (D) The plug must be of the correct size and pressure rating, including any limitations on the test fluid or test temperature. It must be inserted for full length of engagement, in accordance with the plug manufacturer's instructions. (E) The test piece must be so oriented to minimize probability of the plug striking personnel or equipment if the plug is ejected. All air must be vented from objects to be hydrostatically tested. Test plugs shall be barricaded or equipped with arresting devices when pneumatic pressure is used for testing. (F) Provision shall be provided for safe egress. No one shall be allowed to stand in front of the test plug or in line of probable trajectory during test.

(H) Pressurization shall be stopped at intervals to check pressure gage (s) and position of test plug (s). (I) The test pressure shall be reduced to zero before the plugs are loosened for removal. (J) Damaged or expanded closure ends must be cut off. (K) All repairs to test plugs shall follow the plug manufacturer's instructions. (5) Pipe test machines are acceptable for use after they have been reviewed by the Division for safe operational procedures. (6) Pressure during test must be controlled within 5% above the required test procedure. Protection against overpressure must be provided at 110% of the test pressure. A relief valve setting of 133% of the test pressure may be used, for elastic materials only, where calculations show that 133% of the test pressure will not exceed 90% of the specified minimum yield strength of the material. The discharge from the safety relief valve or rupture disc must be led full size to a safe place. The requirement for a relief valve may be waived by a Qualified Pressure Vessel Safety Engineer or Certified Pressure Vessel Inspector if the only source of test pressure is a handpump. (e) Railroad tank cars containing compressed gas may not be used for interrupted unloading into smaller containers, unless permitted by the Federal Department of Transportation. Provisions for such unloading shall conform to DOT regulations See Petroleum Safety Orders, Sections 6879, 6880 and 6881 for requirements covering transfer operations at sidings inside petroleum refineries and distribution plants. (1) An adequate unloading facility must be provided, and provisions must be made to support the transfer hoses. The transfer attendant must not be required to haul the transfer hoses up or down the tank car ladder. (2) A bulkhead must be provided to prevent pullaway of the transfer hoses and/or to prevent imposing piping loads on the tank car valves. The bulkhead must be designed to withstand a horizontal pull of at least 2,000 pounds in any direction unless other adequate protection is provided. The unloading connections shall be firmly secured to the bulkhead. Excess flow valves, check valves or equivalent devices shall be provided where pipe or hose size is reduced. The Qualified Transfer Attendant shall be instructed in all phases of the transfer operation. The instructions shall include a prohibition against overfilling any tank. Note: All valves in the transfer system must be fully open in order for an excess flow valve to function, so internal valves or check valves should be used whenever possible. The tank car excess flow valves are located in the internal piping beneath the dome. Note: Bonding and grounding of the tankcar and transfer equipment may be required for compressed flammable gases by railroad leasing agreement or by the local fire official. (3) Written notification shall be given the Division and the local fire official of each non-permanently equipped transfer site. In emergencies, verbal notice may be given followed by written confirmation. Each such site shall be located, with respect to the minimum distance tables as outlined in Section 501(c) for NH sub3 or Sections 475(a) and (b) for Flammable Compressed Gas. Sites for transfer of other compressed gases must be at least 50 feet from railroad main track or important buildings. The working areas must be kept clear of debris and all transfer equipment must be protected from physical damage. Transfer shall be done only during daylight hours unless the transfer area is equipped with a lighting system and which provides at least 5 foot candles of illumination at all points of operations. (4) Vehicle and tank car wheels must be blocked during transfer. Tank car brakes must be set. Tank cars must not be left connected to hoses and/or pipelines except during the unloading operation and while the qualified transfer attendant is present and in charge, unless the tank car valves are closed and locked, hoses are depressurized and/or a hydrostatic relief valve is installed between shutoff valves. Valves on vehicles must be closed and locked except during transfer. Where vehicular container valves cannot be locked closed, the filling hose(s) must be disconnected when the qualified attendant is not present. (5) Transport tank trucks and towed vehicles may load into the tank cars if they are also equipped with pullaway protection, in addition to meeting the requirements of paragraphs (1) through (4). A brake interlock system that is acceptable to the Division, and is connected to the truck tank unloading hose connection, is considered as an adequate pullaway safeguard. Personal protective devices and safety equipment which are required and used for stationary storage facilities must be provided. Fire extinguishers must be provided for flammable compressed gases and anhydrous ammonia as required by the applicable safety order. Appendix A. Minimum Capacity Requirement Of Relief Valves for Fire Exposure For Liquefied Natural Gas Tanks and Vaporizers A1. The minimum total heat influx during a possible fire exposure of an insulated container shall be computed by the applicable formula: Note: Equation (1) shall be used for vaporizers with external insulation and Equation (2) for uninsulated vaporizers. The value of A is obtained by adding the area of the shell in contact with LN-Gas and the area of heat exchange surface in contact with LN-Gas. (1) H = 1560C sub1 A 0.82 + Hn where: H = Total heat influx, Btu per hour. C sub1 = Conductance of the insulation, Btu/sq. ft.-hr.-deg. F. (The value of C increases with temperature and a mean value for the range from -260 F to 1660 F should be used.) A = Total exposed wetted surface area in sq. ft. Hn = Total normal heat gain to the stored liquid without fire exposures and at maximum ambient temperatures, Btu per hour. A2. If the insulation system, including any jacketing material, is such that it will disappear, deteriorate or dislodge in an exposure fire, a higher heat gain will occur. This requires special consideration depending upon the extent of loss of the insulating properties. If only a part of the insulation is lost, the heat gain may be estimated by the formula: (2) H = (34,500 - 360C sub2)A 0.82 + Hn In this case, the value of C sub2 should be the mean value for the range from -260 degrees F to 100 degrees F. A3. The required relief valve capacity shall be computed by the formula (3) Qa = 3.09(H/L) / (T/M) where: Qa = Required flow capacity of air, cu. ft. per hour at 60 F and 14.7 psia. H = Total heat influx, Btu per hour from the formula (1) or (2). L = Latent heat of vaporization of the stored liquid, Btu per lb. (219 may be used for LN-Gas). T = Absolute temperature of the gas at the relief valve inlet, deg. R. M = Molecular weight of the gas (16.0 may be used for LNG). Appendix B. 3301. [FN1] Use of Compressed Air or Gases. (a) Compressed air and other compressed gases in excess of 10 pounds per square inch gauge shall not be used to blow dirt, chips, or dust from clothing while it is being worn. (b) Compressed air or gases shall not be used to empty containers of liquids where the pressure can exceed the safe working pressure of the container. (c) The use of compressed air shall be so controlled, and proper personal protective equipment or safeguards utilized, as to protect against the possibility of eye or body injury to the operator or other workers. (d) Abrasive blast cleaning nozzles shall be equipped with an operating valve which must be held open manually. A support shall be provided on which the nozzle may be mounted when it is not in use. (e) Compressed gases shall not be used to elevate or otherwise transfer any hazardous substance from one container to another unless the containers are designed to withstand, with a factor of safety of at least four, the maximum possible pressure that may be applied.

[FN2] Miscellaneous Use of Compressed Cylinder Gas. (a) Employers shall not permit the use of compressed cylinder gas for testing pressure vessels unless there is installed in the compressed gas supply line or on the vessel being tested a pressure relief device set to function at a pressure not to exceed the safe working pressure of the vessel. (b) Compressed gas shall never be used from a cylinder or cylinder manifold where pressures dangerous to employees may develop unless an accepted pressure regulating device is installed on the cylinder valve or manifold. The term "accepted" here means that the pressure regulating device is listed by Underwriters' Laboratories or some other recognized authority of equivalent standing.

[FN3] Entering Combustion Chambers, Flues, Boilers or Unfired Steam Pressure Vessels. (a) Before employees are allowed to enter, through a manhole, the shell or drum of a steam boiler or an unfired steam pressure vessel for maintenance or repair, where such a boiler or pressure vessel is one of a battery of two or more boilers or vessels or is connected to another source of steam, the valves connecting to the steam header or other source of steam shall be closed and effectively blinded or two valves shall be installed with a bleeder between them and the valves shall be closed and bleeder open. Blow down valves and other valves on lines through which harmful material might accidentally flow back to the boiler or vessel shall be either sealed or closed and locked and the key retained by the employee or his supervisor while the employee is in the boiler or vessel. When lines are effectively blinded the valves need not be locked or sealed. (b) Employees shall not enter or be required to enter the fire boxes, flues or combustion chambers of fired apparatus until: (1) The pilot light, fuel and steam lines to burners entering the fire box or combustion chamber have been blinded, disconnected or effectively closed by the use of two block valves with an open bleeder between them. (2) All probability of ignition of any solid combustibles in the fire box or combustion chamber has been removed.

(a) Air compressor discharge lines having a block valve between the air receiver and compressor shall have a pressure relieving safety device installed in the line between the compressor and block valve. The pressure relieving safety device shall be set to open at a pressure not to exceed the rated working pressure of the cylinder. The relieving capacity of the pressure relieving safety device shall be such as to prevent a rise of pressure in the compressor cylinder of more than 10 percent above its maximum allowable working pressure, and the discharge shall be to a safe place. The installation of this pressure relieving safety device is not to be considered as providing the required safety relief valve for the protection of the air receiver. (b) Air compressor intake lines shall not be located in atmospheres containing explosive concentrations of flammable gases or vapors.

Appendix C Acceptance Tests for Plastic Piping The following are tests that shall be passed for acceptance of plastic piping for the conveyance of compressed air: 1. Test for impact resistance at 0 <> C: (32 <> F) Objective: To determine if the material will withstand the energy of impact without fracturing through the complete wall thickness. Form of test specimen: Each specimen shall be a section of pipe, of a length equal to twice the nominal size or 150 mm (6" ), whichever is greater, subject to a maximum length of 300 mm (12" ). The ends of the specimen shall be cut clean and equal to the axis of the pipe. For "round-the-clock" testing, each specimen shall be marked with the number of longitudinal lines shown in Table 1. Note: For pipe sizes 50 mm (2 " ) and over, specimens are subjected to impact equally spaced around the pipe; this procedure is known as "round-the-clock" testing. Apparatus: A falling weight machine (an example of which is shown in Figure 1) shall be used and shall consist essentially of the following: a. A main frame which can be rigidly fixed in a true vertical position. b. Guide rails, carried from the inside of the main frame, on side bearings which can be adjusted to keep them parallel and vertical. c. A weighted striker that can fall freely within the guide rails and that is equipped with a hardened hemispherical striking surface 25 mm (1" ) in diameter. The striking surface shall be free from flats and/or other imperfections. d. An appropriate set of weights which can be firmly attached to the striker to enable the combined weight to be adjusted to the values shown in Table 2. Procedure: Adjust the total energy of the striker to the value appropriate to the pipe diameter being tested as shown in Table 2. Condition each specimen in a water or ethylene glycol bath for at least one hour prior to the test at a temperature of 0 <> C (32 <> F) + 1 <>. Test individual specimens within 10 seconds of removal from the bath. allow the striker to fall freely onto the pipe specimen, which is centrally mounted on the vee block support. Specimens from 10 mm (3/8" ) to 38 mm (1-1/2" ) (inclusive) nominal size shall be subjected to a single strike only. For pipe size 50 mm (2" ) and above. Place the pipe on the vee block, so that one of the marked lines is uppermost. Then allow the weight striker to fall freely on the marked line on the pipe as described above. If the specimen does not fail as a result of cracking or splitting through the pipe wall, rotate the specimen until the next marked line is uppermost in the vee block, and cause a second blow to be made by the striker. Repeat the process until all the marked lines have been tested, or until a failure is recorded. If the required sequence of impacts has not been completed within 10 seconds, interrupt the procedure and immediately recondition the specimen at a temperature of 0 <> C (32 <> F) + 1 <> for at least 10 minutes. Fracturing or cracking through the complete wall thickness of the test specimen shall be a failure. The following tests (Nos. 2 & 3) are intended to simulate a potential destructive impact. Splitting through the pipe wall or puncture is acceptable for passing results, if: (a) No separation of one part of piping length from its mating part occurs. (b) No separation of any material fragment from the body of the piping occurs. 2. Test for impact resistance at design pressure at 0 <> C (32 << degrees>> F) with blunt striker. Testing procedures and apparatus shall be the same as Test No. 1, except: (a) Pressurize and maintain pipe sample at design pressure and cool to 0 << degrees>> C (32 <> F) as in Test No. 1. (b) Energy of the striker to be twice the total energy of Table 2. (c) Only one drop required. 3. Test for impact resistance at design pressure at 0 <> C (32 << degrees>> F) with sharp striker. Same as Test No. 2 in all cases, except with a chisel edged sharp striker (Figure 2). 4. The plastic piping systems shall be capable of sustaining without failure at least 600 psi when tested to the Standard Test Method for Short-Time Hydraulic Failure Pressure of Plastic Pipe, Tubing, and Fittings, using ASTM Designation No. D1599-86 (1986) which is herein incorporated by reference.

(a) All boilers subject to these Orders are subject to annual internal and external inspection, except as provided in subsection (b), and except those boilers exempted from annual inspection in Section 771. (b) Boilers installed in turboelectric plants in such a manner that each boiler furnishes steam to a single turbine only shall be inspected internally at least once each eighteen (18) months. The permit to operate issued following internal inspection shall expire not more than twelve (12) months after the date of inspection. The boiler shall be externally inspected prior to or on the expiration date of the permit by a qualified inspector who may, if conditions warrant, issue a temporary permit which shall expire not more than six (6) months after the date of external inspection. A copy of the external inspection report shall be forwarded to the Division by the qualified inspector. Such report shall show the expiration date of the temporary permit to operate. The Division, upon individual application from petroleum companies, chemical plants, public utilities or other industries considered by the Division as having superior preventive maintenance and examination programs, may grant a maximum interval of thirty-six (36) months between internal inspection of fired boilers. A fired boiler is defined for this section as one whose temperature input can cause metallurgical damage to the boiler, or whose combustion of fuel can cause a furnace explosion. For boilers other than fired boilers, the Division may grant a maximum interval of seventy-two (72) months between internal inspections, provided the temperature input cannot cause metallurgical damage. Boilers of the latter type are typically called process steam generators. Such applications, to be reviewed by the Division, shall contain as a minimum the following information and proposals: (1) The history of the unit (or of a similar installation) that shows that there is no significant deterioration from scaling, corrosion, erosion or overheating. (2) Wall thickness reference points shall be established. Following internal inspection of each boiler, a complete record showing the total corrosion and any other conditions found which need correction at the time of inspection shall be forwarded to the Division as part of the inspection report required by 774(a)(1). This record shall show the location and extent of any corrosion, erosion or other defects noted and shall be verified and signed by the certified inspector making the inspection required by Section 770(a). (3) The "Permit to Operate" shall expire one (1) year from the date of the internal inspection, or the date of startup if so noted on the inspection report and the "Permit to Operate." Prior to or on the expiration date of this "Permit," a certified inspector, who will review the operating logs and water treatment records, shall inspect the boiler externally. If conditions warrant, the certified inspector may issue a temporary permit not to exceed six (6) months. Prior to or on the expiration date of the second permit, the boiler shall again be inspected externally by a certified inspector; if conditions warrant, a "Permit" may be issued for an additional six (6) months. Boilers operating longer than twenty-four (24) months between internal inspections shall have a program of on-stream examination of corrosion points, and inspection of operations and safety controls that is acceptable to the Division, and the certified inspection agency. The maximum interval of each temporary permit shall be six (6) months. If the boiler is located within a local jurisdiction that has regulations concerning boiler inspections, the jurisdiction must also be consulted concerning the acceptability of the inspection program. The certified inspector shall submit reports to the Division of each external inspection, noting the expiration date of the permit issued, and recording any unusual condition found. The inspection report shall include a statement that water treatment records have been reviewed. Reports of on-stream wall thickness readings must also be submitted to the Division via the certified inspector. (4) For boilers and process steam generators where metallurgical damage may occur, the Division may categorize the boiler or process steam generator as unfired upon acceptance of a risk engineering analysis submitted by the owner of the boiler to the Division. The risk engineering analysis shall include the design basis for categorizing the boiler as unfired, the potential consequences to the boiler and to the safety of the person(s) responsible for attending the boiler, and a discussion of protective devices and specific procedures to prevent the consequences. (5) The boiler water treatment and specific chemical limits shall be prescribed by a competent water treatment specialist, such as a chemical engineer. The boiler water chemistry shall be maintained within desirable limits and documentary records shall be kept of the tests and methods used to maintain the water chemistry within the prescribed limits. A summary of weekly test results shall be kept, and the records shall be available to the certified inspector. (6) A copy of the Division letter granting the longer interval between internal inspections shall be posted near the boiler, the boiler control center, or the process unit control room.

(c) Calking edges of girth seams, provided the metal remaining between the rivet and calking edge to be built up is at least fifty percent (50%) of the original thickness and also provided the length of calking edge to be built up does not exceed a length equal to the diameter of the boiler. Before any welding is done, all rivets in the affected area and six inches (6 ") beyond each portion to be built up shall be removed. After the welded repair has been completed the rivet holes shall be reamed and new rivets driven. (d) The building up or repair by welding of rivet heads, staybolts, braces, or attachments to braces, or grooved areas is not permitted. (e) Scattered pits and corrosion in unstayed shells may be built up by welding, provided the largest dimension of such corroded area does not exceed the diameter of an unreinforced opening in paragraph PG-32 of the Code and providing such areas are not so located that they form a ligament in the longitudinal direction. s 789. Permissible Repair by Seal Welding. (a) The ends of all tubes, suspension tubes, and nipples of water-tube boilers and superheaters may be seal-welded in accordance with the provisions of paragraph PWT-11 of the Code. (b) Seal-welding of circumferential joints is permissible, provided the seam is calked first and made tight under hydrostatic pressure equal to the working pressure. (c) The ends of fire tubes may be seal-welded provided the thickness of the tube is at least seventy-five percent (75%) of its original thickness, and the tubes are first rolled and beaded and found tight under hydrostatic pressure at least equal to the working pressure. The throat of the weld shall not exceed three-sixteenths inch (3/16 "). s 790. Permissible Tube Repair. (a) All the tubes in a firetube boiler may be retipped, provided the tube wall thickness of the original tube is not less than ninety percent (90%) of the original thickness and the retipped ends are from new material. The new end shall be located in the tube sheet subject to the greatest heat. The circumferential welds in such tubes shall not exceed four (4) in number. (b) Complete replacement of sections of tubes or pipe in water-tube boilers is permitted, providing the remaining tube is not less than the thickness required for the designed working pressure and the requirements of paragraph PW-41 of the Code are complied with. (c) Bulges in tubes of water-tube boilers may be repaired when: (1) The maximum dimension of the repaired area does not exceed the diameter of the tube or two inches (2 ") whichever is the least. (2) There are not more than three (3) such repairs in any one (1) tube. (3) The tube wall adjacent to the bulge is not less than the thickness required for the designed working pressure. (4) The requirements of paragraph PW-41 of the Code are complied with. s 793. Qualification of Welding Procedures and Operators. No welded repair shall be made to any boiler or boiler appurtenance until the welding procedure and operator have been qualified in accordance with Section IX of the code in the overhead and horizontal positions. The certificate of competency number of the qualified inspector authorizing the repair shall be stamped adjacent to all welded repairs made to power boilers. On welded repairs that are completely radiographed the operator qualification may be eliminated at the discretion of the division provided the welding procedure is properly qualified inspector indicates on his report the welding procedure used and the operator employed in making the repair. s 794. Riveted Patches. (a) Riveted patch seams exposed to the products of combustion may be double-riveted or constructed similar to the original seams of the boiler. (b) Patches exceeding twenty-four inches (24 ") in length shall have the proper width as determined by these orders. Patches exceeding fifteen inches (15 ") to and including twenty-four inches (24 ") in length shall be triangular, crescent, diamond, or oval in shape and width, W, in the circumferential direction, shall be at least twice the length, L, in the longitudinal direction. Patches fifteen inches (15 ") or less in longitudinal direction may be circular in shape. (c) If it is found that a patch will extend extremely high, and also to avoid calking in sharp corners, it may be shortened in width to the extent that not more than four (4) rivets will be in a longitudinal line, as shown in Figure 2. (d) If it is found that a patch will have to be sixty inches (60 ") or more in length, consideration should be given to the use of a sheet having a width equivalent to five-eighths (5/8) of the circumference of the boiler, and the longitudinal seam shall be of a design similar to the design of the original seam of the boiler. (e) In laying out new patches over twenty-four inches (24 ") long, it is recommended that they be triangular or diamond in shape as may be required for the particular job; with definite straight-line sides but with corners properly rounded to permit adequate caulking, as illustrated in Figures 1, 2, 3, and 4. The length designated as "L" and the width designated as "W" are also shown in Figures 1, 2, 3, and 4. (f) Rivets shall be used in "riveted" patch seams unless their use is difficult or impossible, in which case, patch bolts may be used. Rivet holes may be countersunk in patches on shells that have the heads supported by tubes or braces, providing the angle of the chamfer with the center line of the rivet hole does not exceed forty-five degrees (45 degrees), and the depth does not exceed half the thickness of the plate. (g) Patch material shall be of fire box or flange steel depending upon the plate it replaces. Tank steel shall not be used. The repair shop shall be required to produce a copy of the manufacturer's mill test report for the material to be used. (h) The patch plate material shall contain the steelmaker's brand. If only a part of a plate is required and this part does not contain the brand, the brand shall be transferred to the patch plate in the presence of a qualified inspector or a representative of the plate manufacturer before the plate is cut. Replacement rivets, patch bolts, and staybolts shall be of material approved for new construction by the code. (i) All patch plates except patch plates containing blowoff connections shall be placed inside of the boiler shell or drum if exposed to the products of combustion and if installed where there is a possibility that scale deposits may be pocketed. Patch plates containing blowoff connections shall be placed on the outside of the boiler shell. s 795. Installation of Riveted Patches. (a) The following procedure shall be followed when installing riveted patches: (1) Distorted sheets which require patching shall first be set back straight as nearly as possible before proceeding with the cutting out of the plate so that the patch may be kept as small as possible. (2) All defective or deteriorated material shall be removed and properly trimmed to provide for caulking and neat workmanship in attaching the patch. (3) The edges of a patch shall be beveled for calking by planing, chipping, or gas cutting before applying it to the boiler. Rivets should be driven by gun, if at all possible. (4) All rivet holes shall be drilled full size or the holes may be punched not to exceed one-fourth inch (1/4 ") less than full size for plates over five-sixteenths inch (5/16 "), and one-eighth inch (1/8 ") less than full size for plates five-sixteenths inch (5/16 ") or less in thickness, and then reamed to full size with patch in place. Rivet holes shall be not more than one-sixteenth inch (1/16 ") greater in diameter than the nominal diameter of the rivet. (5) Seal welding of the patch plate is permissible if a single bead is used with a throat thickness not more than three-sixteenths inch (3/16 "). The patch shall be tight under a hydrostatic test pressure equal to the operating pressure before seal welding. Rivets and patch bolts shall not be seal welded. (6) When three (3) plates are lapped at the corners of a patch, the middle plate shall be scarfed carefully to a feather edge the entire width of the lap as shown in Figure 1. (7) Upon the completion of repairs, a hydrostatic test of one hundred fifty percent (150%) of the maximum allowable operating pressure shall be applied. All seams shall be tight at this pressure. s 796. Riveted Patch Seam Calculations. (a) Riveted patch seams are calculated as follows: (1) Determine the length, L, of the patch from the area of the defect to be repaired (Figures 1, 2, 3, and 4). The normal efficiency, e, of the single-riveted seam that is to be used in the patch should then be determined from Table 1. This is governed by the thickness of plate and diameter of rivet holes. Table 1 EFFICIENCIES OF SINGLE -RIVETED SEAMS Plate ............ Rivet Hole ......... Pitch of ........... Efficiency of Thickness, t ..... Diameter, d ........ Rivet, p ........... Seam, e 1/4 .............. 11/16 .............. 1 7/8 .............. 63.6 9/32 ............. 3/4 ................ 1 7/8 .............. 60.3 5/16 ............. 3/4 ................ 1 7/8 .............. 60.0 11/32 ............ 13/16 .............. 1 15/16 ............ 58.0 3/8 .............. 13/16 .............. 1 15/16 ............ 57.0 13/32 ............ 7/8 ................ 2 1/16 ............. 57.5 7/16 ............. 15/16 .............. 2 1/4 .............. 56.0 15/32 ............ 15/16 .............. 2 1/8 .............. 55.5 1/2 .............. 1 .................. 2 1/4 .............. 55.7 9/16 ............. 1 1/16 ............. 2 3/8 .............. 53.0 19/32 ............ 1 1/16 ............. 2 1/4 .............. 52.8 5/8 .............. 1 1/16 ............. 2 1/4 .............. 50.5 21/32 ............ 1 1/8 .............. 2 5/16 ............. 51.4 11/16 ............ 1 1/8 .............. 2 5/16 ............. 51.4 Tensile strength assumed at 55,000 psi and shearing strength at 44,000 psi. After determining the length, L, of a patch, determine its width girthwise, W. This is found by multiplying the length by the constant, C, as shown in Table 2 or 3, depending upon the type of boiler to be repaired. These tables give a constant, C, for a given efficiency, e, of patch and efficiency, E, of the longitudinal seam. (2) To determine the longitudinal efficiency of an existing patch, the length, L, and width, W, the pitch, P, and the diameter, d, of rivet, should be measured. "W" divided by "L" will give the constant, C. Table 1 will give "e." Then under "e" in Table 2 or 3, depending upon the type of boiler to be repaired, find the constant, C. Whatever "E" is in the first column is the longitudinal or allowed efficiency of the patch seam. s 797. Example of the Application and Explanation of Patch Tables and Charts. (a) A patch is to be placed in the fire sheet of a horizontal return tubular boiler having a shell plate seven-sixteenths-inch (7/16 ") thick, a longitudinal seam efficiency of seventy-four percent (74%), and a length of patch of thirty-six inches (36 "). Find the width, W, of patch to be applied so that there will be no reduction in pressure, using a single-riveted seam of normal design. Referring to Table 1, it is found that seven-sixteenths-inch (7/16 ") plate with fifteen-sixteenths-inch (15/16 ") diameter rivet holes, pitched two and one-fourth (2 1/4) gives a seam efficiency of fifty-six percent (56%). Referring to Table 2, E = 0.74 and e = 0.56 gives a constant C = 1.75; then width W = L x C = 36 x 1.75 = sixty-three inches (63 "). (b) Pressure Allowed on an Existing Patch. A crescent-shaped patch has already been installed on a horizontal-tubular boiler. It is thirty inches (30 ") long and forty-eight inches (48 ") wide. The seam is single riveted with thirteen-sixteenths-inch (13/16 ") rivet holes pitched one and fifteen-sixteenths inches (1 15/16 "). The boiler shell plate is three-eighths-inch (3/8 ") thick. The longitudinal seam is of the double-riveted butt-strap type having an efficiency of eighty-two percent (82%). The safety valve is set for one hundred twenty-five pounds (125#) pressure. What maximum pressure should be allowed on the boiler? Reference to Table 1, shows that the normal efficiency of the patch seam is fifty-seven percent (57%). (If the efficiency is not found in the Table, refer to any other available table or determine it in the manner described in paragraphs A-1, A-2 and A-3 of the Appendix of the A.S.M.E. Boiler Code.) Divide the width of the patch, W = forty-eight inches (48 ") by the length, L = thirty inches (30 ") to find the constant, C = 48/30 = 1.60. Follow down column 0.57 of Table 2 until 1.60 is found. It will be noted that this is somewhere between 1.56 and 1.62 representing E somewhere between 0.72 and 0.73. As the difference between 1.56 and 1.62 is 6, and the difference between 1.56 and 1.60 is 4, E will be 0.72 plus 4/6 of 0.01 which is 0.7266. The maximum allowable working pressure varies directly as the seam efficiency. Accordingly, P = (0.7266/0.82) x 125 = 110#. If this pressure allowance interferes with the operation of the plant, the patch shall be replaced by a new one with the proper dimensions giving a diagonal efficiency of eighty-two percent (82%). (c) Design of Patch for Water-tube Boiler. Reference to Table 1 shows that a single-riveted lap seam with seven-sixteenths-inch (7/16 ") plate, fifteen-sixteenths-inch (15/16 ") diameter rivet holes, and two-and-one-half-inch (2 1/2 ") pitch has a normal efficiency of fifty-six percent (56%). Reference to Table 3, shows E = 0.82 and e = 0.56, the constant C is 3.16. Then width W = C x 1 / 2. W = 3.16 x 36 / 2 = 56.88 or practically fifty-seven inches (57 ").

(1) On multi-employer worksites, an employer performing work requiring the establishment of a regulated area shall inform other employers on the site of the nature of the employer's work with asbestos and/or PACM, of the existence of and requirements pertaining to regulated areas, and the measures taken to ensure that employees of such other employers are not exposed to asbestos. (2) Asbestos hazards at a multi-employer work site shall be abated by the contractor who created or controls the source of asbestos contamination. For example, if there is a significant breach of an enclosure containing Class I work, the employer responsible for erecting the enclosure shall repair the breach immediately. (3) In addition, all employers of employees exposed to asbestos hazards shall comply with applicable protective provisions to protect their employees. For example, if employees working immediately adjacent to a Class I asbestos job are exposed to asbestos due to the inadequate containment of such job, their employer shall either remove the employees from the area until the enclosure breach is repaired; or perform an initial exposure assessment pursuant to subsection (f) of this section. (4) All employers of employees working adjacent to regulated areas established by another employer on a multi-employer work-site, shall take steps on a daily basis to ascertain the integrity of the enclosure and/or the effectiveness of the control method relied on by the primary asbestos contractor to assure that asbestos fibers do not migrate to such adjacent areas. (5) All general contractors on a construction project which includes work covered by this standard shall be deemed to exercise general supervisory authority over the work covered by this standard, even though the general contractor is not qualified to serve as the asbestos "competent person" as defined by subsection (b) of this section. As supervisor of the entire project, the general contractor shall ascertain whether the asbestos contractor is in compliance with this standard, and shall require such contractor to come into compliance with this standard when necessary. (e) Regulated areas. (1) All Class I, II and III asbestos work shall be conducted within regulated areas. All other operations covered by this standard shall be conducted within a regulated area where airborne concentrations of asbestos exceed, or there is a reasonable possibility they may exceed a PEL. Regulated areas shall comply with the requirements of subsections (2), (3), (4), and (5) of this subsection. (2) Demarcation. The regulated area shall be demarcated in any manner that minimizes the number of persons within the area and protects persons outside the area from exposure to airborne asbestos. Where critical barriers or negative pressure enclosures are used, they may demarcate the regulated area. Signs shall be provided and displayed pursuant to the requirements of subsection (k)(7) of this section. (3) Access. Access to regulated areas shall be limited to authorized persons and to persons authorized by the Chief or Director. (4) Respirators.

(5) Prohibited activities. The employer shall ensure that employees do not eat, drink, smoke, chew tobacco or gum, or apply cosmetics in the regulated area. (6) Competent Persons. The employer shall ensure that all asbestos work performed within regulated areas is supervised by a competent person, as defined in subsection (b) of this section. The duties of the competent person are set out in subsection (o) of this section. (f) Exposure assessments and monitoring. (1) General monitoring criteria. (A) Each employer who has a workplace or work operation where exposure monitoring is required under this section shall perform monitoring to determine accurately the airborne concentrations of asbestos to which employees may be exposed. (B) Determinations of employee exposure shall be made from breathing zone air samples that are representative of the 8-hour TWA and 30-minute short-term exposures of each employee. (C) Representative 8-hour TWA employee exposure shall be determined on the basis of one or more samples representing full-shift exposure for employees in each work area. Representative 30-minute short-term employee exposures shall be determined on the basis of one or more samples representing 30 minute exposures associated with operations that are most likely to produce exposures above the excursion limit for employees in each work area. (2) Initial Exposure Assessment. (A) Each employer who has a workplace or work operation covered by this standard shall ensure that a "competent person" conducts an exposure assessment immediately before or at the initiation of the operation to ascertain expected exposures during that operation or workplace. The assessment must be completed in time to comply with requirements which are triggered by exposure data or the lack of a "negative exposure assessment," and to provide information necessary to assure that all control systems planned are appropriate for that operation and will work properly. (B) Basis of Initial Exposure Assessment: Unless a negative exposure assessment has been made pursuant to subsection (f)(2)(C) of this section, the initial exposure assessment shall, if feasible, be based on monitoring conducted pursuant to subsection (f)(1)(C) of this section. The assessment shall take into consideration both the monitoring results and all observations, information or calculations which indicate employee exposure to asbestos, including any previous monitoring conducted in the workplace, or of the operations of the employer which indicate the levels of airborne asbestos likely to be encountered on the job. For Class I asbestos work, until the employer conducts exposure monitoring and documents that employees on that job will not be exposed in excess of the PELs, or otherwise makes a negative exposure assessment pursuant to subsection (f)(2)(C) of this section, the employer shall presume that employees are exposed in excess of the TWA and excursion limit. (C) Negative Exposure Assessment: For any one specific asbestos job which will be performed by employees who have been trained in compliance with the standard, the employer may demonstrate that employee exposures will be below the PELs by data which conform to the following criteria; 1. Objective data demonstrating that the product or material containing asbestos minerals or the activity involving such product or material cannot release airborne fibers in concentrations exceeding the TWA and excursion limit under those work conditions having the greatest potential for releasing asbestos; or 2. Where the employer has monitored prior asbestos jobs for the PEL and the excursion limit within 12 months of the current or projected job, the monitoring and analysis were performed in compliance with the asbestos standard in effect; and the data were obtained during work operations conducted under workplace conditions "closely resembling" the processes, type of material, control methods, work practices, and environmental conditions used and prevailing in the employer's current operations, the operations were conducted by employees whose training and experience are no more extensive than that of employees performing the current job, and these data show that under the conditions prevailing and which will prevail in the current workplace there is a high degree of certainty that employee exposures will not exceed the TWA and excursion limit; or 3. The results of initial exposure monitoring of the current job made from breathing zone air samples that are representative of the 8-hour TWA and 30- minute short-term exposures of each employee covering operations which are most likely during the performance of the entire asbestos job to result in exposures over the PELs. (3) Periodic monitoring. (A) Class I and II operations. The employer shall conduct daily monitoring that is representative of the exposure of each employee who is assigned to work within a regulated area who is performing Class I or II work, unless the employer pursuant to subsection (f)(2)(C) of this section, has made a negative exposure assessment for the entire operation. (B) All operations under the standard other than Class I and II operations. The employer shall conduct periodic monitoring of all work where exposures are expected to exceed a PEL, at intervals sufficient to document the validity of the exposure prediction. (C) Exception: When all employees required to be monitored daily are equipped with supplied-air respirators operated in the pressure demand mode, or other positive pressure mode respirator, the employer may dispense with the daily monitoring required by this subsection. However, employees performing class I work using a control method which is not listed in subsection (g)(4)(A), (B), or (C) of this section or using a modification of a listed control method, shall continue to be monitored daily even if they are equipped with supplied-air respirators. (4) Termination of monitoring. (A) If the periodic monitoring required by subsection (f)(3) of this section reveals that employee exposures, as indicated by statistically reliable measurements, are below the permissible exposure limit and excursion limit the employer may discontinue monitoring for those employees whose exposures are represented by such monitoring. (B) Additional monitoring. Notwithstanding the provisions of subsections (f)(2), (f)(3), and (f)(4) of this section, the employer shall institute the exposure monitoring required under subsection (f)(3) of this section whenever there has been a change in process, control equipment, personnel or work practices that may result in new or additional exposures above the permissible exposure limit and/or excursion limit or when the employer has any reason to suspect that a change may result in new or additional exposures above the permissible exposure limit and/or excursion limit. Such additional monitoring is required regardless of whether a "negative exposure assessment" was previously produced for a specific job. (5) Employee Notification of Monitoring Results. (A) As soon as possible but not later than 5 working days following receipt of monitoring results required by this section, the employer shall notify affected employees of the monitoring results. (B) The employer shall notify affected employees of the results of monitoring representing the employee's exposure in writing either individually or by posting at a centrally located place that is accessible to affected employees. (C) The written notification required by subsection (f)(5)(A) of this section shall include the corrective action being taken by the employer to reduce employee exposure to or below the PEL and/or excursion limit wherever monitoring results have indicated that the PEL and/or excursion limit has been exceeded. (6) Observation of monitoring. (A) The employer shall provide affected employees and their designated representatives an opportunity to observe any monitoring of employee exposure to asbestos conducted in accordance with this section. (B) When observation of the monitoring of employee exposure to asbestos requires entry into an area where the use of protective clothing or equipment is required, the observer shall be provided with and be required to use such clothing and equipment and shall comply with all other applicable safety and health procedures. (g) Methods of compliance (1) Engineering controls and work practices for all operations covered by this section.

(k) Communication of hazards. (1) This section applies to the communication of information concerning asbestos hazards in construction activities to facilitate compliance with this standard. Most asbestos-related construction activities involve previously installed building materials. Building owners often are the only and/or best sources of information concerning them. Therefore, they, along with employers of potentially exposed employees, are assigned specific information conveying and retention duties under this section. Installed Asbestos Containing Building Material. Employers and building owners shall identify TSI and sprayed or troweled on surfacing materials in buildings as asbestos-containing, unless they determine in compliance with subsection (k)(5) of this section that the material is not asbestos-containing. Asphalt and vinyl flooring material installed no later than 1980 must also be considered as asbestos containing unless the employer, pursuant to subsection (g)(8)(A)9. of this section determines that it is not asbestos-containing. If the employer/building owner has actual knowledge, or should have known through the exercise of due diligence, that other materials are asbestos-containing, they too must be treated as such. When communicating information to employees pursuant to this standard, owners and employers shall identify "PACM" as ACM. Additional requirements relating to communication of asbestos work on multi-employer worksites are set out in subsection (d) of this section. (2) Duties of building and facility owners. (A) Before work subject to this standard is begun, building and facility owners shall determine the presence, location, and quantity of ACM and/or PACM at the work site pursuant to subsection (k)(1) of this section.

Notification either shall be in writing, or shall consist of a personal communication between the owner and the person to whom notification must be given or their authorized representatives: 1. Prospective employers applying or bidding for work whose employees reasonably can be expected to work in or adjacent to areas containing such material; 2. Employees of the owner who will work in or adjacent to areas containing such material: 3. On multi-employer worksites, all employers of employees who will be performing work within or adjacent to areas containing such materials; 4. Tenants who will occupy areas containing such material. (3) Duties of employers whose employees perform work subject to this standard in or adjacent to areas containing ACM and PACM. Building/facility owners whose employees perform such work shall comply with these provisions to the extent applicable. (A) Before work in areas containing ACM and PACM is begun; employers shall identify the presence, location, and quantity of ACM, and/or PACM therein pursuant to subsection (k)(1) of this section. (B) Before work under this standard is performed employers of employees who will perform such work shall inform the following persons of the location and quantity of ACM and/or PACM present in the area and the precautions to be taken to insure that airborne asbestos is confined to the area. 1. Owners of the building/facility; 2. Employees who will perform such work and employers of employees who work and/or will be working in adjacent areas. (C) Within 10 days of the completion of such work, the employer whose employees have performed work subject to this standard, shall inform the building/facility owner and employers of employees who will be working in the area of the current location and quantity of PACM and/or ACM remaining in the area and final monitoring results, if any. (4) In addition to the above requirements, all employers who discover ACM and/or PACM on a worksite shall convey information concerning the presence, location and quantity of such newly discovered ACM and/or PACM to the owner and to other employers of employees working at the work site, within 24 hours of the discovery. (5) Criteria to rebut the designation of installed material as PACM.

Building owners and/or employers are not required to communicate information about the presence of building material for which such a demonstration pursuant to the requirements of subsection (k)(5)(B) of this section has been made. However, in all such cases, the information, data and analysis supporting the determination that PACM does not contain asbestos, shall be retained pursuant to subsection (n) of this section. (B) An employer or owner may demonstrate that PACM does not contain more than 1% asbestos by the following: 1. Having completed an inspection conducted pursuant to the requirements of AHERA (40 CFR Part 763, Subpart E) which demonstrates that the material is not ACM or; 2. Performing tests of the material containing PACM which demonstrate that no ACM is present in the material. Such tests shall include analysis of bulk samples collected in the manner described in 40 CFR 763.86. The tests, evaluation and sample collection shall be conducted by an accredited inspector or by a CIH. Analysis of samples shall be performed by persons or laboratories with proficiency demonstrated by current successful participation in a nationally recognized testing program such as the National Voluntary Laboratory Accreditation Program (NVLAP) or the National Institute for Standards and Technology (NIST) or the Round Robin for bulk samples administered by the American Industrial Hygiene Association (AIHA) or an equivalent nationally-recognized round robin testing program. (C) The employer and/or building owner may demonstrate that flooring material including associated mastic and backing does not contain asbestos, by a determination of an industrial hygienist based upon recognized analytical techniques showing that the material is not ACM. (6) At the entrance to mechanical rooms/areas in which employees reasonably can be expected to enter and which contain thermal system insulation and surfacing ACM and/or PACM, the building owner shall post signs which identify the material which is present, its location, and appropriate work practices which, if followed, will ensure that ACM and/or PACM will not be disturbed. The employer shall ensure, to the extent feasible, that employees who come in contact with these signs can comprehend them. Means to ensure employee comprehension may include the use of foreign languages, pictographs, graphics, and awareness training. (7) Signs.

Appendix A. OSHA Reference Method Mandatory This mandatory appendix specifies the procedure for analyzing air samples for asbestos and specifies quality control procedures that must be implemented by laboratories performing the analysis. The sampling and analytical methods described below represent the elements of the available monitoring methods (such as appendix B to this section, the most current version of the OSHA method ID-60, or the most current version of the NIOSH 7400 method) which OSHA considers to be essential to achieve adequate employee exposure monitoring while allowing employers to use methods that are already established within their organizations. All employers who are required to conduct air monitoring under subsection (f) of this section are required to utilize analytical laboratories that use this procedure, or an equivalent method, for collecting and analyzing samples. Sampling and Analytical Procedure 1. The sampling medium for air samples shall be mixed cellulose ester filter membranes. These shall be designated by the manufacturer as suitable for asbestos counting. See below for rejection of blanks. 2. The preferred collection device shall be the 25-mm diameter cassette with an open-faced 50-mm extension cowl. The 37-mm cassette may be used if necessary but only if written justification for the need to use the 37-mm filter cassette accompanies the sample results in the employee's exposure monitoring record. Do not reuse or reload cassettes for asbestos sample collection. 3. An air flow rate between 0.5 liter/min and 2.5 liters/min shall be selected for the 25-mm cassette. If the 37-mm cassette is used, an air flow rate between 1 liter/min and 2.5 liters/min shall be selected. 4. Where possible, a sufficient air volume for each air sample shall be collected to yield between 100 and 1,300 fibers per square millimeter on the membrane filter. If a filter darkens in appearance or if loose dust is seen on the filter, a second sample shall be started. 5. Ship the samples in a rigid container with sufficient packing material to prevent dislodging the collected fibers. Packing material that has a high electrostatic charge on its surface (e.g., expanded polystyrene) cannot be used because such material can cause loss of fibers to the sides of the cassette. 6. Calibrate each personal sampling pump before and after use with a representative filter cassette installed between the pump and the calibration devices. 7. Personal samples shall be taken in the "breathing zone" of the employee (i.e., attached to or near the collar or lapel near the worker's face). 8. Fiber counts shall be made by positive phase contrast using a microscope with an 8 to 10 X eyepiece and a 40 to 45 X objective for a total magnification of approximately 400 X and a numerical aperture of 0.65 to 0.75. The microscope shall also be fitted with a green or blue filter. 9. The microscope shall be fitted with a Walton-Beckett eyepiece graticule calibrated for a field diameter of 100 micrometers (+/- 2 micrometers). 10. The phase-shift detection limit of the microscope shall be about 3 degrees measured using the HSE phase shift test slide as outlined below. a. Place the test slide on the microscope stage and center it under the phase objective. b. Bring the blocks of grooved lines into focus. Note: The slide consists of seven sets of grooved lines (ca. 20 grooves to each block) in descending order of visibility from sets 1 to 7, seven being the least visible. The requirements for asbestos counting are that the microscope optics must resolve the grooved lines in set 3 completely, although they may appear somewhat faint, and that the grooved lines in sets 6 and 7 must be invisible. Sets 4 and 5 must be at least partially visible but may vary slightly in visibility between microscopes. A microscope that fails to meet these requirements has either too low or too high a resolution to be used for asbestos. c. If the image deteriorates, clean and adjust the microscope optics. If the problem persists, consult the microscope manufacturer. 11. Each set of samples taken will include 10% field blanks or a minimum of 2 field blanks. These blanks must come from the same lot as the filters used for sample collection. The field blank results shall be averaged and subtracted from the analytical results before reporting. A set consists of any sample or group of samples for which an evaluation for this standard must be made. Any samples represented by a field blank having a fiber count in excess of the detection limit of the method being used shall be rejected. 12. The samples shall be mounted by the acetone/triacetin method or a method with an equivalent index of refraction and similar clarity. 13. Observe the following counting rules. a. Count only fibers equal to or longer than 5 micrometers. Measure the length of curved fibers along the curve. b. Count all particles as asbestos that have a length-to-width ratio (aspect ratio) of 3:1 or greater. c. Fibers lying entirely within the boundary of the Walton-Beckett graticule field shall receive a count of 1. Fibers crossing the boundary once, having one end within the circle, shall receive the count of one half (1/2). Do not count any fiber that crosses the graticule boundary more than once. Reject and do not count any other fibers even though they may be visible outside the graticule area. d. Count bundles of fibers as one fiber unless individual fibers can be identified by observing both ends of an individual fiber. e. Count enough graticule fields to yield 100 fibers. Count a minimum of 20 fields; stop counting at 100 fields regardless of fiber count. 14. Blind recounts shall be conducted at the rate of 10 percent. Quality Control Procedures 1. Intra-laboratory program. Each laboratory and/or each company with more than one microscopist counting slides shall establish a statistically designed quality assurance program involving blind recounts and comparisons between microscopists to monitor the variability of counting by each microscopist and between microscopists. In a company with more than one laboratory, the program shall include all laboratories and shall also evaluate the laboratory-to-laboratory variability. 2. a. Interlaboratory program. Each laboratory analyzing asbestos samples for compliance determination shall implement an interlaboratory quality assurance program that as a minimum includes participation of at least two other independent laboratories. Each laboratory shall participate in round robin testing at least once every 6 months with at least all the other laboratories in its interlaboratory quality assurance group. Each laboratory shall submit slides typical of its own work load for use in this program. The round robin shall be designed and results analyzed using appropriate statistical methodology. b. All laboratories should participate in a national sample testing scheme such as the Proficiency Analytical Testing Program (PAT), the Asbestos Registry sponsored by the American Industrial Hygiene Association (AIHA). 3. All individuals performing asbestos analysis must have taken the NIOSH course for sampling and evaluating airborne asbestos dust or an equivalent course. 4. When the use of different microscopes contributes to differences between counters and laboratories, the effect of the different microscopes shall be evaluated and the microscopes shall be replaced, as necessary. 5. Current results of these quality assurance programs shall be posted in each laboratory to keep the microscopists informed. Note: Authority cited: Section 142.3, Labor Code.

Introduction This method describes the collection of airborne asbestos fibers using calibrated sampling pumps with mixed-cellulose ester (MCE) filters and analysis by phase contrast microscopy (PCM). Some terms used are unique to this method and are defined below: Asbestos: A term for naturally occurring fibrous minerals. Asbestos includes chrysotile, crocidolite, amosite (cummingtonite-grunerite asbestos), tremolite asbestos, actinolite asbestos, anthophyllite asbestos, and any of these minerals that have been chemically treated and/or altered. The precise chemical formulation of each species will vary with the location from which it was mined. Nominal compositions are listed: Chrysotile................. Mg 3 Si 2 O 5 (OH) 4 Crocidolite................ Na 2 Fe 3 2+ Fe 2+3+ Si 8 O 22 (OH) 2 Amosite.................... (Mg,Fe) 7 Si 8 O 22 (OH) 2 Tremolite-actinolite....... Ca 2 (Mg,Fe) 5 Si 8 O 22 (OH) 2 Anthophyllite.............. (Mg,Fe) 7 Si 8 O 22 (OH) 2 Asbestos Fiber: A fiber of asbestos which meets the criteria specified below for a fiber. Aspect Ratio: The ratio of the length of a fiber to it's diameter (e.g. 3:1, 5:1 aspect ratios). Cleavage Fragments: Mineral particles formed by comminution of minerals, especially those characterized by parallel sides and a moderate aspect ratio (usually less than 20:1). Detection Limit: The number of fibers necessary to be 95% certain that the result is greater than zero. Differential Counting: The term applied to the practice of excluding certain kinds of fibers from the fiber count because they do not appear to be asbestos. Fiber: A particle that is 5 m m or longer, with a length-to-width ratio of 3 to 1 or longer. Field: The area within the graticule circle that is superimposed on the microscope image. Set: The samples which are taken, submitted to the laboratory, analyzed, and for which, interim or final result reports are generated. Tremolite, Anthophyllite, and Actinolite: The non-asbestos form of these minerals which meet the definition of a fiber. It includes any of these minerals that have been chemically treated and/or altered. Walton-Beckett Graticule: An eyepiece graticule specifically designed for asbestos fiber counting. It consists of a circle with a projected diameter of 100 plus or minus 2 m m (area of about 0.00785 mm 2) with a crosshair having tic-marks at 3- m m intervals in one direction and 5- m m in the orthogonal direction. There are marks around the periphery of the circle to demonstrate the proper sizes and shapes of fibers. This design is reproduced in Figure 1. of this appendix. The disk is placed in one of the microscope eyepieces so that the design is superimposed on the field of view. 1.1. History Early surveys to determine asbestos exposures were conducted using impinger counts of total dust with the counts expressed as million particles per cubic foot. The British Asbestos Research Council recommended filter membrane counting in 1969. In July 1969, the Bureau of Occupational Safety and Health published a filter membrane method for counting asbestos fibers in the United States. This method was refined by NIOSH and published as P & CAM 239. On May 29, 1971, OSHA specified filter membrane sampling with phase contrast counting for evaluation of asbestos exposures at work sites in the United States. The use of this technique was again required by OSHA in 1986. Phase contrast microscopy has continued to be the method of choice for the measurement of occupational exposure to asbestos. 1.2. Principle Air is drawn through a MCE filter to capture airborne asbestos fibers. A wedge shaped portion of the filter is removed, placed on a glass microscope slide and made transparent. A measured area (field) is viewed by PCM. All the fibers meeting defined criteria for asbestos are counted and considered a measure of the airborne asbestos concentration. 1.3. Advantages and Disadvantages There are four main advantages of PCM over other methods: (1) The technique is specific for fibers. Phase contrast is a fiber counting technique which excludes non-fibrous particles from the analysis. (2) The technique is inexpensive and does not require specialized knowledge to carry out the analysis for total fiber counts. (3) The analysis is quick and can be performed on-site for rapid determination of air concentrations of asbestos fibers. (4) The technique has continuity with historical epidemiological estimates of expected disease can be inferred from long-term determinations of asbestos exposures. The main disadvantage of PCM is that it does not positively identify asbestos fibers. Other fibers which are not asbestos may be included in the count unless differential counting is performed. This requires a great deal of experience to adequately differentiate asbestos from non-asbestos fibers. Positive identification of asbestos must be performed by polarized light or electron microscopy techniques. A further disadvantage of PCM is that the smallest visible fibers are about 0.2 m m in diameter while the finest asbestos fibers may be as small as 0.02 m m in diameter. For some exposures, substantially more fibers may be present than are actually counted. 1.4. Workplace Exposure Asbestos is used by the construction industry in such products as shingles, floor tiles, asbestos cement, roofing felts, insulation and acoustical products. Non-construction uses include brakes, clutch facings, paper, paints, plastics, and fabrics. One of the most significant exposures in the workplace is the removal and encapsulation of asbestos in schools, public buildings, and homes. Many workers have the potential to be exposed to asbestos during these operations. About 95% of the asbestos in commercial use in the United States is chrysotile. Crocidolite and amosite make up most of the remainder. Anthophyllite and tremolite or actinolite are likely to be encountered as contaminants in various industrial products. 1.5. Physical Properties Asbestos fiber possesses a high tensile strength along its axis, is chemically inert, non-combustible, and heat resistant. It has a high electrical resistance and good sound absorbing properties. It can be weaved into cables, fabrics or other textiles, and also matted into asbestos papers, felts, or mats. 2. Range and Detection Limit 2.1. The ideal counting range on the filter is 100 to 1,300 fibers/mm 2 With a Walton-Beckett graticule this range is equivalent to 0.8 to 10 fibers/field. Using NIOSH counting statistics, a count of 0.8 fibers/field would give an approximate coefficient of variation (CV) of 0.13. 2.2. The detection limit for this method is 4.0 fibers per 100 fields or 5.5 fibers/mm 2. This was determined using an equation to estimate the maximum CV possible at a specific concentration (95% confidence) and a Lower Control Limit of zero. The CV value was then used to determine a corresponding concentration from historical CV vs fiber relationships. As an example: Lower Control Limit (95% Confidence) = AC - 1.645(CV)(AC) Where: AC = Estimate of the airborne fiber concentration (fibers/cc) Setting the Lower Control Limit = 0 and solving for CV: 0 = AC - 1.645(CV)(AC) CV = 0.61 This value was compared with CV vs. count curves. The count at which CV = 0.61 for Leidel-Busch counting statistics or for an OSHA Salt Lake Technical Center (OSHA-SLTC) CV curve (see Appendix A for further information) was 4.4 fibers or 3.9 fibers per 100 fields, respectively. Although a lower detection limit of 4 fibers per 100 fields is supported by the OSHA-SLTC data, both data sets support the 4.5 fibers per 100 fields value. 3. Method Performance - Precision and Accuracy Precision is dependent upon the total number of fibers counted and the uniformity of the fiber distribution on the filter. A general rule is to count at least 20 and not more than 100 fields. The count is discontinued when 100 fibers are counted, provided that 20 fields have already been counted. Counting more than 100 fibers results in only a small gain in precision. As the total count drops below 10 fibers, an accelerated loss of precision is noted. At this time, there is no known method to determine the absolute accuracy of the asbestos analysis. Results of samples prepared through the Proficiency Analytical Testing (PAT) Program and analyzed by the OSHA-SLTC showed no significant bias when compared to PAT reference values. The PAT samples were analyzed from 1987 to 1989 (N=36) and the concentration range was from 120 to 1,300 fibers/mm(2). 4. Interferences Fibrous substances, if present, may interfere with asbestos analysis. Some common fibers are: fiberglass anhydrite plant fibers perlite veins gypsum some synthetic fibers membrane structures sponge spicules diatoms microorganisms wollastonite The use of electron microscopy or optical tests such as polarized light, and dispersion staining may be used to differentiate these materials from asbestos when necessary. 5. Sampling 5.1. Equipment 5.1.1. Sample assembly.

Membrane filter, mixed-cellulose ester (MCE), 25-mm, plain, white, 0.4- to 1.2- m m pore size. Notes: (a) DO NOT RE-USE CASSETTES. (b) Fully conductive cassettes are required to reduce fiber loss to the sides of the cassette due to electrostatic attraction. (c) Purchase filters which have been selected by the manufacturer for asbestos counting or analyze representative filters for fiber background before use. Discard the filter lot if more than 4 fibers/100 fields are found. (d) To decrease the possibility of contamination, the sampling system (filter-backup pad-cassette) for asbestos is usually preassembled by the manufacturer. (e) Other cassettes, such as the Bell-mouth, may be used within the limits of their validation. 5.1.2. Gel bands for sealing cassettes. 5.1.3. Sampling pump. Each pump must be a battery operated, self- contained unit small enough to be placed on the monitored employee and not interfere with the work being performed. The pump must be capable of sampling at the collection rate for the required sampling time. 5.1.4. Flexible tubing, 6-mm bore. 5.1.5. Pump calibration. Stopwatch and bubble tube/burette or electronic meter. 5.2. Sampling Procedure 5.2.1. Seal the point where the base and cowl of each cassette meet with a gel band or tape. 5.2.2. Charge the pumps completely before beginning. 5.2.3. Connect each pump to a calibration cassette with an appropriate length of 6-mm bore plastic tubing. Do not use luer connectors - the type of cassette specified above has built-in adapters. 5.2.4. Select an appropriate flow rate for the situation being monitored. The sampling flow rate must be between 0.5 and 5.0 L/min for personal sampling and is commonly set between 1 and 2 L/min. Always choose a flow rate that will not produce overloaded filters. 5.2.5. Calibrate each sampling pump before and after sampling with a calibration cassette in-line (Note: This calibration cassette should be from the same lot of cassettes used for sampling). Use a primary standard (e.g. bubble burette) to calibrate each pump. If possible, calibrate at the sampling site. Note: If sampling site calibration is not possible, environmental influences may affect the flow rate. The extent is dependent on the type of pump used. Consult with the pump manufacturer to determine dependence on environmental influences. If the pump is affected by temperature and pressure changes, correct the flow rate using the formula shown in the section "Sampling Pump Flow Rate Corrections" at the end of this appendix. 5.2.6. Connect each pump to the base of each sampling cassette with flexible tubing. Remove the end cap of each cassette and take each air sample open face. Assure that each sample cassette is held open side down in the employee's breathing zone during sampling. The distance from the nose/mouth of the employee to the cassette should be about 10 cm. Secure the cassette on the collar or lapel of the employee using spring clips or other similar devices. 5.2.7. A suggested minimum air volume when sampling to determine TWA compliance is 25 L. For Excursion Limit (30 min sampling time) evaluations, a minimum air volume of 48 L is recommended. 5.2.8. The most significant problem when sampling for asbestos is overloading the filter with non-asbestos dust. Suggested maximum air sample volumes for specific environments are: Environment ................................. Air Vol. (L) Asbestos removal operations (visible dust) .. 100. Asbestos removal operations (little dust) ... 240. Office environments. 400 to 2,400. CAUTION: Do not overload the filter with dust. High levels of non- fibrous dust particles may obscure fibers on the filter and lower the count or make counting impossible. If more than about 25 to 30% of the field area is obscured with dust, the result may be biased low. Smaller air volumes may be necessary when there is excessive non-asbestos dust in the air. While sampling, observe the filter with a small flashlight. If there is a visible layer of dust on the filter, stop sampling, remove and seal the cassette, and replace with a new sampling assembly. The total dust loading should not exceed 1 mg. 5.2.9. Blank samples are used to determine if any contamination has occurred during sample handling. Prepare two blanks for the first 1 to 20 samples. For sets containing greater than 20 samples, prepare blanks as 10% of the samples. Handle blank samples in the same manner as air samples with one exception: Do not draw any air through the blank samples. Open the blank cassette in the place where the sample cassettes are mounted on the employee. Hold it open for about 30 seconds. Close and seal the cassette appropriately. Store blanks for shipment with the sample cassettes. 5.2.10. Immediately after sampling, close and seal each cassette with the base and plastic plugs. Do not touch or puncture the filter membrane as this will invalidate the analysis. 5.2.11. Attach and secure a sample seal around each sample cassette in such a way as to assure that the end cap and base plugs cannot be removed without destroying the seal. Tape the ends of the seal together since the seal is not long enough to be wrapped end-to-end. Also wrap tape around the cassette at each joint to keep the seal secure. 5.3. Sample Shipment 5.3.1. Send the samples to the laboratory with paperwork requesting asbestos analysis. List any known fibrous interferences present during sampling on the paperwork. Also, note the workplace operation(s) sampled. 5.3.2. Secure and handle the samples in such that they will not rattle during shipment nor be exposed to static electricity. Do not ship samples in expanded polystyrene peanuts, vermiculite, paper shreds, or excelsior. Tape sample cassettes to sheet bubbles and place in a container that will cushion the samples in such a manner that they will not rattle. 5.3.3. To avoid the possibility of sample contamination, always ship bulk samples in separate mailing containers. 6. Analysis 6.1. Safety Precautions 6.1.1. Acetone is extremely flammable and precautions must be taken not to ignite it. Avoid using large containers or quantities of acetone. Transfer the solvent in a ventilated laboratory hood. Do not use acetone near any open flame. For generation of acetone vapor, use a spark free heat source. 6.1.2. Any asbestos spills should be cleaned up immediately to prevent dispersal of fibers. Prudence should be exercised to avoid contamination of laboratory facilities or exposure of personnel to asbestos. Asbestos spills should be cleaned up with wet methods and/or a High Efficiency Particulate Air (HEPA) filtered vacuum. CAUTION: Do not use a vacuum without a HEPA filter - It will disperse fine asbestos fibers in the air. 6.2. Equipment 6.2.1. Phase contrast microscope with binocular or trinocular head. 6.2.2. Widefield or Huygenian 10X eyepieces (NOTE: The eyepiece containing the graticule must be a focusing eyepiece. Use a 40X phase objective with a numerical aperture of 0.65 to 0.75). 6.2.3. Kohler illumination (if possible) with green or blue filter. 6.2.4. Walton-Beckett Graticule, type G-22 with 100 plus or minus 2 m m projected diameter. 6.2.5. Mechanical stage. A rotating mechanical stage is convenient for use with polarized light. 6.2.6. Phase telescope. 6.2.7. Stage micrometer with 0.01-mm subdivisions. 6.2.8. Phase-shift test slide, mark II (Available from PTR optics Ltd., and also McCrone). 6.2.9. Precleaned glass slides, 25 mm X 75 mm. One end can be frosted for convenience in writing sample numbers, etc., or paste-on labels can be used. 6.2.10. Cover glass #1 1/2. 6.2.11. Scalpel (#10, curved blade). 6.2.12. Fine tipped forceps. 6.2.13. Aluminum block for clearing filter (see Appendix D). 6.2.14. Automatic adjustable pipette, 100-to 500- m L. 6.2.15. Micropipette, 5 m L. 6.3. Reagents 6.3.1. Acetone (HPLC grade). 6.3.2. Triacetin (glycerol triacetate). 6.3.3. Lacquer or nail polish. 6.4. Standard Preparation A way to prepare standard asbestos samples of known concentration has not been developed. It is possible to prepare replicate samples of nearly equal concentration. This has been performed through the PAT program. These asbestos samples are distributed by the AIHA to participating laboratories. Since only about one-fourth of a 25-mm sample membrane is required for an asbestos count, any PAT sample can serve as a "standard" for replicate counting. 6.5. Sample Mounting Note: See Safety Precautions in Section 6.1. before proceeding. The objective is to produce samples with a smooth (non-grainy) background in a medium with a refractive index of approximately 1.46. The technique below collapses the filter for easier focusing and produces permanent mounts which are useful for quality control and interlaboratory comparison. An aluminum block or similar device is required for sample preparation. 6.5.1. Heat the aluminum block to about 70 deg.C. The hot block should not be used on any surface that can be damaged by either the heat or from exposure to acetone. 6.5.2. Ensure that the glass slides and cover glasses are free of dust and fibers. 6.5.3. Remove the top plug to prevent a vacuum when the cassette is opened. Clean the outside of the cassette if necessary. Cut the seal and/or tape on the cassette with a razor blade. Very carefully separate the base from the extension cowl, leaving the filter and backup pad in the base. 6.5.4. With a rocking motion cut a triangular wedge from the filter using the scalpel. This wedge should be one-sixth to one-fourth of the filter. Grasp the filter wedge with the forceps on the perimeter of the filter which was clamped between the cassette pieces. DO NOT TOUCH the filter with your finger. Place the filter on the glass slide sample side up. Static electricity will usually keep the filter on the slide until it is cleared. 6.5.5. Place the tip of the micropipette containing about 200 m L acetone into the aluminum block. Insert the glass slide into the receiving slot in the aluminum block. Inject the acetone into the block with slow, steady pressure on the plunger while holding the pipette firmly in place. Wait 3 to 5 seconds for the filter to clear, then remove the pipette and slide from the aluminum block. 6.5.6. Immediately (less than 30 seconds) place 2.5 to 3.5 m L of triacetin on the filter (NOTE: Waiting longer than 30 seconds will result in increased index of refraction and decreased contrast between the fibers and the preparation. This may also lead to separation of the cover slip from the slide). 6.5.7. Lower a cover slip gently onto the filter at a slight angle to reduce the possibility of forming air bubbles. If more than 30 seconds have elapsed between acetone exposure and triacetin application, glue the edges of the cover slip to the slide with lacquer or nail polish. 6.5.8. If clearing is slow, warm the slide for 15 min on a hot plate having a surface temperature of about 50 deg.C to hasten clearing. The top of the hot block can be used if the slide is not heated too long. 6.5.9. Counting may proceed immediately after clearing and mounting are completed. 6.6. Sample Analysis Completely align the microscope according to the manufacturer's instructions. Then, align the microscope using the following general alignment routine at the beginning of every counting session and more often if necessary. 6.6.1. Alignment (1) Clean all optical surfaces. Even a small amount of dirt can significantly degrade the image. (2) Rough focus the objective on a sample. (3) Close down the field iris so that it is visible in the field of view. Focus the image of the iris with the condenser focus. Center the image of the iris in the field of view. (4) Install the phase telescope and focus on the phase rings. Critically center the rings. Misalignment of the rings results in astigmatism which will degrade the image. (5) Place the phase-shift test slide on the microscope stage and focus on the lines. The analyst must see line set 3 and should see at least parts of 4 and 5 but, not see line set 6 or 6. A microscope/microscopist combination which does not pass this test may not be used. 6.6.2. Counting Fibers (1) Place the prepared sample slide on the mechanical stage of the microscope. Position the center of the wedge under the objective lens and focus upon the sample. (2) Start counting from one end of the wedge and progress along a radial line to the other end (count in either direction from perimeter to wedge tip). Select fields randomly, without looking into the eyepieces, by slightly advancing the slide in one direction with the mechanical stage control. (3) Continually scan over a range of focal planes (generally the upper 10 to 15 m m of the filter surface) with the fine focus control during each field count. Spend at least 5 to 15 seconds per field. (4) Most samples will contain asbestos fibers with fiber diameters less than 1 m m. Look carefully for faint fiber images. The small diameter fibers will be very hard to see. However, they are an important contribution to the total count. (5) Count only fibers equal to or longer than 5 m m. Measure the length of curved fibers along the curve. (6) Count fibers which have a length to width ratio of 3:1 or greater. (7) Count all the fibers in at least 20 fields. Continue counting until either 100 fibers are counted or 100 fields have been viewed; whichever occurs first. Count all the fibers in the final field. (8) Fibers lying entirely within the boundary of the Walton-Beckett graticule field shall receive a count of 1. Fibers crossing the boundary once, having one end within the circle shall receive a count of 1/2. Do not count any fiber that crosses the graticule boundary more than once. Reject and do not count any other fibers even though they may be visible outside the graticule area. If a fiber touches the circle, it is considered to cross the line. (9) Count bundles of fibers as one fiber unless individual fibers can be clearly identified and each individual fiber is clearly not connected to another counted fiber. See Figure 1 of this appendix for counting conventions. (10) Record the number of fibers in each field in a consistent way such that filter non-uniformity can be assessed. (11) Regularly check phase ring alignment. (12) When an agglomerate (mass of material) covers more than 25% of the field of view, reject the field and select another. Do not include it in the number of fields counted. (13) Perform a "blind recount" of 1 in every 10 filter wedges (slides). Re-label the slides using a person other than the original counter. 6.7. Fiber Identification As previously mentioned in Section 1.3., PCM does not provide positive confirmation of asbestos fibers. Alternate differential counting techniques should be used if discrimination is desirable. Differential counting may include primary discrimination based on morphology, polarized light analysis of fibers, or modification of PCM data by Scanning Electron or Transmission Electron Microscopy. A great deal of experience is required to routinely and correctly perform differential counting. It is discouraged unless it is legally necessary. Then, only if a fiber is obviously not asbestos should it be excluded from the count. Further discussion of this technique can be found in reference 8.10. If there is a question whether a fiber is asbestos or not, follow the rule: "WHEN IN DOUBT, COUNT." 6.8. Analytical Recommendations - Quality Control System 6.8.1. All individuals performing asbestos analysis must have taken the NIOSH course for sampling and evaluating airborne asbestos or an equivalent course. 6.8.2. Each laboratory engaged in asbestos counting shall set up a slide trading arrangement with at least two other laboratories in order to compare performance and eliminate inbreeding of error. The slide exchange occurs at least semiannually. The round robin results shall be posted where all analysts can view individual analyst's results. 6.8.3. Each laboratory engaged in asbestos counting shall participate in the Proficiency Analytical Testing Program, the Asbestos Analyst Registry or equivalent. 6.8.4. Each analyst shall select and count prepared slides from a "slide bank". These are quality assurance counts. The slide bank shall be prepared using uniformly distributed samples taken from the workload. Fiber densities should cover the entire range routinely analyzed by the laboratory. These slides are counted blind by all counters to establish an original standard deviation. This historical distribution is compared with the quality assurance counts. A counter must have 95% of all quality control samples counted within three standard deviations of the historical mean. This count is then integrated into a new historical mean and standard deviation for the slide. The analyses done by the counters to establish the slide bank may be used for an interim quality control program if the data are treated in a proper statistical fashion. 7. Calculations 7.1. Calculate the estimated airborne asbestos fiber concentration on the filter sample using the following formula: where: AC = Airborne fiber concentration FB = Total number of fibers greater than 5 m m counted FL = Total number of fields counted on the filter BFB = Total number of fibers greater than 5 m m counted in the blank BFL = Total number of fields counted on the blank ECA = Effective collecting area of filter (385 mm(2) nominal for a 25 - mm filter.) FR = Pump flow rate (L/min) MFA = Microscope count field area (mm(2)). This is 0.00785 mm(2) for a Walton-Beckett Graticule. T = Sample collection time (min) 1,000 = Conversion of L to cc Note: The collection area of a filter is seldom equal to 385 mm(2). It is appropriate for laboratories to routinely monitor the exact diameter using an inside micrometer. The collection area is calculated according to the formula: Area = / (d /2) 2 7.2. Short-Cut Calculation Since a given analyst always has the same interpupillary distance, the number of fields per filter for a particular analyst will remain constant for a given size filter. The field size for that analyst is constant (i.e. the analyst is using an assigned microscope and is not changing the reticle). For example, if the exposed area of the filter is always 385 mm(2) and the size of the field is always 0.00785 mm(2) the number of fields per filter will always be 49,000. In addition it is necessary to convert liters of air to cc. These three constants can then be combined such that ECA/(1,000 x MFA)=49. The previous equation simplifies to: 7.3. Recount Calculations As mentioned in step 13 of Section 6.6.2., a "blind recount" of 10% of the slides is performed. In all cases, differences will be observed between the first and second counts of the same filter wedge. Most of these differences will be due to chance alone, that is, due to the random variability (precision) of the count method. Statistical recount criteria enables one to decide whether observed differences can be explained due to chance alone or are probably due to systematic differences between analysts, microscopes, or other biasing factors. The following recount criterion is for a pair of counts that estimate AC in fibers/cc. The criterion is given at the type-I error level. That is, there is 5% maximum risk that we will reject a pair of counts for the reason that one might be biased, when the large observed difference is really due to chance. Reject a pair of counts if: Where: AC(1) = lower estimated airborne fiber concentration AC(2) = higher estimated airborne fiber concentration AC(avg) = average of the two concentration estimates CV(FB) = CV for the average of the two concentration estimates If a pair of counts are rejected by this criterion then, recount the rest of the filters in the submitted set. Apply the test and reject any other pairs failing the test. Rejection shall include a memo to the industrial hygienist stating that the sample failed a statistical test for homogeneity and the true air concentration may be significantly different than the reported value. 7.4. Reporting Results Report results to the industrial hygienist as fibers/cc. Use two significant figures. If multiple analyses are performed on a sample, an average of the results is to be reported unless any of the results can be rejected for cause. 8. References 8.1.

The following is presented as an example of how the OSHA-SLTC constructed its internal CV curve as part of meeting this requirement. Data is from 395 samples collected during OSHA compliance inspections and analyzed from October 1980 through April 1986. Each sample was counted by 2 to 5 different counters independently of one another. The standard deviation and the CV statistic was calculated for each sample. This data was then plotted on a graph of CV vs. fibers/mm 2. A least squares regression was performed using the following equation: CV = antilog 10 [A(log 10 (x)) 2 +B(log 10 (x))+C] where: x = the number of fibers/mm 2 Application of least squares gave: A = 0.182205 B = 0.973343 C = 0.327499 Using these values, the equation becomes: CV = antilog 10 [0.182205(log 10 (x)) 2 + 0.973343(log 10 (x)) + 0.327499] Sampling Pump Flow Rate Corrections This correction is used if a difference greater than 5% in ambient temperature and/or pressure is noted between calibration and sampling sites and the pump does not compensate for the differences. Where: Q(act) = actual flow rate Q(cal) = calibrated flow rate (if a rotameter was used, the rotameter value) P(cal) = uncorrected air pressure at calibration P(act) = uncorrected air pressure at sampling site T(act) = temperature at sampling site (K) T(cal) = temperature at calibration (K) Walton-Beckett Graticule When ordering the Graticule for asbestos counting, specify the exact disc diameter needed to fit the ocular of the microscope and the diameter (mm) of the circular counting area. Instructions for measuring the dimensions necessary are listed: (1) Insert any available graticule into the focusing eyepiece and focus so that the graticule lines are sharp and clear. (2) Align the microscope. (3) Place a stage micrometer on the microscope object stage and focus the microscope on the graduated lines. (4) Measure the magnified grid length, PL ( m m), using the stage micrometer. (5) Remove the graticule from the microscope and measure its actual grid length, AL (mm). This can be accomplished by using a mechanical stage fitted with verniers, or a jeweler's loupe with a direct reading scale. (6) Let D = 100 m m. Calculate the circle diameter, d(c)(mm), for the Walton-Beckett graticule and specify the diameter when making a purchase: AL x D d c = _________ PL Example: If PL = 108 m m, AL = 2.93 mm and D = 100 m m, then, 2.93 x 100 d c = ___________ = 2.71mm 108 (7) Each eyepiece-objective-reticle combination on the microscope must be calibrated. Should any of the three be changed (by zoom adjustment, disassembly, replacement, etc.), the combination must be recalibrated. Calibration may change if interpupillary distance is changed. Measure the field diameter, D (acceptable range: 100 plus or minus 2 m m) with a stage micrometer upon receipt of the graticule from the manufacturer. Determine the field area (mm(2)). Field Area = PI( D /2) 2 If D = 100 MU = 0.1 mm, then Field Area = PI(0.1 mm /2) 2 = 0.00785mm 2 The Graticule is available from: Graticules Ltd., Morley Road, Tonbridge TN9 IRN, Kent, England (Telephone 011-44-732-359061).

Work Practices and Engineering Controls for Class I Asbestos Operations (Non- mandatory) This is a non-mandatory appendix to the asbestos standards for construction and for shipyards. It describes criteria and procedures for erecting and using negative pressure enclosures for Class I Asbestos Work, when NPEs are used as an allowable control method to comply with subsection (g)(5)(A) of this section. Many small and variable details are involved in the erection of a negative pressure enclosure. OSHA and most participants in the rulemaking agreed that only the major, more performance oriented criteria should be made mandatory. These criteria are set out in subsection (g) of this section. In addition, this appendix includes these mandatory specifications and procedures in its guidelines in order to make this appendix coherent and helpful. The mandatory nature of the criteria which appear in the regulatory text is not changed because they are included in this "non-mandatory" appendix. Similarly, the additional criteria and procedures included as guidelines in the appendix, do not become mandatory because mandatory criteria are also included in these comprehensive guidelines. In addition, none of the criteria, both mandatory and recommended, are meant to specify or imply the need for use of patented or licensed methods or equipment. Recommended specifications included in this attachment should not discourage the use of creative alternatives which can be shown to reliably achieve the objectives of negative-pressure enclosures. Requirements included in this appendix, cover general provisions to be followed in all asbestos jobs, provisions which must be followed for all Class I asbestos jobs, and provisions governing the construction and testing of negative pressure enclosures. The first category includes the requirement for use of wet methods, HEPA vacuums, and immediate bagging of waste; Class I work must conform to the following provisions: * oversight by competent person * use of critical barriers over all openings to work area * isolation of HVAC systems * use of impermeable dropcloths and coverageof all objects within regulated areas In addition, more specific requirements for NPEs include: * maintenance of -0.02 inches water gauge within enclosure * manometric measurements * air movement away from employees performing removal work * smoke testing or equivalent for detection of leaks and air direction * deactivation of electrical circuits, if not provided with ground-fault circuit interrupters. Planning the Project The standard requires that an exposure assessment be conducted before the asbestos job is begun [Subsection 1529(f)(1)]. Information needed for that assessment, includes data relating to prior similar jobs, as applied to the specific variables of the current job. The information needed to conduct the assessment will be useful in planning the project, and in complying with any reporting requirements under this standard, when significant changes are being made to a control system listed in the standard, [see also those of USEPA (40 CFR 61, subpart M). Thus, although the standard does not explicitly require the preparation of a written asbestos removal plan, the usual constituents of such a plan, i.e., a description of the enclosure, the equipment, and the procedures to be used throughout the project, must be determined before the enclosure can be erected. The following information should be included in the planning of the system: A physical description of the work area; A description of the approximate amount of material to be removed; A schedule for turning off and sealing existing ventilation systems; Personnel hygiene procedures; A description of personal protective equipment and clothing to be worn by employees; A description of the local exhaust ventilation systems to be used and how they are to be tested; A description of work practices to be observed by employees; An air monitoring plan; A description of the method to be used to transport waste material; and The location of the dump site. Materials and Equipment Necessary for Asbestos Removal Although individual asbsetos removal projects vary in terms of the equipment required to accomplish the removal of the materials, some equipment and materials are common to most asbestos removal operations. Plastic sheeting used to protect horizontal surfaces, seal HVAC openings or to seal vertical openings and ceilings should have a minimum thickness of 6 mils. Tape or other adhesive used to attach plastic sheeting should be of sufficient adhesive strength to support the weight of the material plus all stresses encountered during the entire duration of the project without becoming detached from the surface. Other equipment and materials which should be available at the beginning of each project are: - HEPA Filtered Vacuum is essential for cleaning the work area after the asbestos has been removed. It should have a long hose capable of reaching out-of-the-way places, such as areas above ceiling tiles, behind pipes, etc. - Portable air ventilation systems installed to provide the negative air pressure and air removal from the enclosure must be equipped with a HEPA filter. The number and capacity of units required to ventilate an enclosure depend on the size of the area to be ventilated. The filters for these systems should be designed in such a manner that they can be replaced when the air flow is reduced by the build-up of dust in the filtration material. Pressure monitoring devices with alarms and strip chart recorders attached to each system to indicate the pressure differential and the loss due to dust buildup on the filter are recommended. - Water sprayers should be used to keep the asbsetos material as saturated as possible during removal; the sprayers will provide a fine mist that minimizes the impact of the spray on the material. - Water used to saturate the asbestos containing material can be amended by adding at least 15 milliliters (1/4 ounce) of wetting agent in 1 liter (1 pint) of water. An example of a wetting agent is a 50/50 mixture of polyoxyethylene ether and polyoxyethylene polyglycol ester. - Backup power supplies are recommended, especially for ventilation systems. - Shower and bath water should be with mixed hot and cold water faucets. Water that has been used to clean personnel or equipment should either be filtered or be collected and discarded as asbestos waste. Soap and shampoo should be provided to aid in removing dust from the workers' skin and hair. - See subsections (h) and (i) of this section for appropriate respiratory protection and protective clothing. - See subsection (k) of this section for required signs and labels. Preparing the Work Area Disabling the HVAC Systems: The power to the heating, ventilation and air conditioning systems that service the restricted area must be deactivated and locked off. All ducts, grills, access ports, windows and vents must be sealed off with two layers of plastic to prevent entrainment of contaminated air. Operating HVAC Systems in the Restricted Area: If components of a HVAC system located in the restricted area are connected to a system that will service another zone during the project, the portion of the duct in the restricted area must be sealed and pressurized. Necessary precautions include caulking the duct joints, covering all cracks and openings with two layers of sheeting, and pressurizing the duct throughout the duration of the project by restricting the return of air flow. The power to the fan supplying the positive pressure should be locked "on" to prevent pressure loss. Sealing Elevators: If an elevator shaft is located in the restricted area, it should be either shut down or isolated by sealing with two layers of plastic sheeting. The sheeting should provide enough slack to accommodate the pressure changes in the shaft without breaking the air-tight seal. Removing Mobile Objects: All movable objects should be cleaned and removed from the work area before an enclosure is constructed unless moving the objects creates a hazard. Mobile objects will be assumed to be contaminated and should be either cleaned with amended water and a HEPA vacuum and then removed from the area or wrapped and then disposed of as hazardous waste. Cleaning and Sealing Surfaces: After cleaning with water and a HEPA vacuum, surfaces of stationary objects should be covered with two layers of plastic sheeting. The sheeting should be secured with duct tape or an equivalent method to provide a tight seal around the object. Bagging Waste: In addition to the requirement for immediate bagging of waste for disposal, it is further recommended that the waste material be double-bagged and sealed in plastic bags designed for asbestos disposal. The bags should be stored in a waste storage area that can be controlled by the workers conducting the removal. Filters removed from handling units and rubbish removed from the area are to be bagged and handled as hazardous waste. Constructing the Enclosure The enclosure should be constructed to provide an air-tight seal around ducts and openings into existing ventilation systems and around penetrations for electrical conduits, telephone wires, water lines, drain pipes, etc. Enclosures should be both airtight and watertight except for those openings designed to provide entry and/or air flow control. Size: An enclosure should be the minimum volume to encompass all of the working surfaces yet allow unencumbered movement by the worker(s), provide unrestricted air flow past the worker(s), and ensure walking surfaces can be kept free of tripping hazards. Shape: The enclosure may be any shape that optimizes the flow of ventilation air past the worker(s). Structural Integrity: The walls, ceilings and floors must be supported in such a manner that portions of the enclosure will not fall down during normal use. Openings: It is not necessary that the structure be airtight; openings may be designed to direct air flow. Such openings should be located at a distance from active removal operations. They should be designed to draw air into the enclosure under all anticipated circumstances. In the event that negative pressure is lost, they should be fitted with either HEPA filters to trap dust or automatic trap doors that prevent dust from escaping the enclosure. Openings for exits should be controlled by an airlock or a vestibule. Barrier Supports: Frames should be constructed to support all unsupported spans of sheeting. Sheeting: Walls, barriers, ceilings and floors should be lined with two layers of plastic sheeting having a thickness of at least 6 mil. Seams: Seams in the sheeting material should be minimized to reduce the possibilities of accidental rips and tears in the adhesive or connections. All seams in the sheeting should overlap, be staggered and not be located at corners or wall-to-floor joints. Areas Within an Enclosure: Each enclosure consists of a work area, a decontamination area, and waste storage area. The work area where the asbestos removal operations occur should be separated from both the waste storage area and the contamination control area by physical curtains, doors, and/or airflow patterns that force any airborne contamination back into the work area. See subsection (j) of this section for requirements for hygiene facilities. During egress from the work area, each worker should step into the equipment room, clean tools and equipment, and remove gross contamination from clothing by wet cleaning and HEPA vacuuming. Before entering the shower area, foot coverings, head coverings, hand coverings and coveralls are removed and placed in impervious bags for disposal or cleaning. Airline connections from airline respirators with HEPA disconnects and power cables from powered air-purifying respirators (PAPRs) will be disconnected just prior to entering the showering room. Establishing Negative Pressure Within the Enclosure Negative Pressure: Air is to be drawn into the enclosure under all anticipated conditions and exhausted through a HEPA filter for 24 hours a day during the entire duration of the project. Air Flow Tests: Air flow patterns will be checked before removal operations begin, at least once per operating enclosure. The primary test for air flow is to trace air currents with smoke tubes or other visual methods. Flow checks are made at each opening and at each doorway to demonstrate that air is being drawn into the enclosure and to each worker's position to show that air is being drawn away from the breathing zone. Monitoring Pressure Within the Enclosure: After the initial air flow patterns have been checked, the static pressure must be monitored within the enclosure. Monitoring may be made using manometers, pressure gauges, or combinations of these devices. It is recommended that they be attached to alarms and strip chart recorders at points identified by the design engineer. Corrective Actions: If the manometers or pressure gauges demonstrate a reduction in pressure differential below the required level, work should cease and the reason for the change investigated and appropriate changes made. The air flow patterns should be retested before work begins again. Pressure Differential: The design parameters for static pressure differentials between the inside and outside of enclosures typically range from 0.02 to 0.10 inches of water gauge, depending on conditions. All zones inside the enclosure must have less pressure than the ambient pressure outside of the enclosure (-0.02 inches water gauge differential). Design specifications for the differential vary according to the size, configuration, and shape of the enclosure as well as ambient and mechanical air pressure conditions around the enclosure. Air Flow Patterns: The flow of air past each worker shall be enhanced by positioning the intakes and exhaust ports to remove contaminated air from the worker's breathing zone, by positioning HEPA vacuum cleaners to draw air from the worker's breathing zone, by forcing relatively uncontaminated air past the worker toward an exhaust port, or by using a combination of methods to reduce the worker's exposure. Air Handling Unit Exhaust: The exhaust plume from air handling units should be located away from adjacent personnel and intakes for HVAC systems. Air Flow Volume: The air flow volume (cubic meters per minute) exhausted (removed) from the workplace must exceed the amount of makeup air supplied to the enclosure. The rate of air exhausted from the enclosure should be designed to maintain a negative pressure in the enclosure and air movement past each worker. The volume of air flow removed from the enclosure should replace the volume of the container at every 5 to 15 minutes. Air flow volume will need to be relatively high for large enclosures, enclosures with awkward shapes, enclosures with multiple openings, and operations employing several workers in the enclosure. Air Flow Velocity: At each opening, the air flow velocity must visibly "drag" air into the enclosure. The velocity of the air flow within the enclosure must be adequate to remove airborne contamination from each worker's breathing zone without disturbing the asbestos-containing material on surfaces. Airlocks: Airlocks are mechanisms on doors and curtains that control the air flow patterns in the doorways. If air flow occurs, the patterns through doorways must be such that the air flows toward the inside of the enclosure. Sometimes vestibules, double doors, or double curtains are used to prevent air movement through the doorways. To use a vestibule, a worker enters a chamber by opening the door or curtain and then closing the entry before opening the exit door or curtain. Airlocks should be located between the equipment room and shower room, between the shower room and the clean room, and between the waste storage area and the outside of the enclosure. The air flow between the adjacent rooms must be checked using smoke tubes or other visual tests to ensure the flow patterns draw air toward the work area without producing eddies. Monitoring for Airborne Concentrations In addition to the breathing zone samples taken as outlined in subsection (f) of this section, samples of air should be taken to demonstrate the integrity of the enclosure, the cleanliness of the clean room and shower area, and the effectiveness of the HEPA filter. If the clean room is shown to be contaminated, the room must be relocated to an uncontaminated area. Samples taken near the exhaust of portable ventilation systems must be done with care. General Work Practices Preventing dust dispersion is the primary means of controlling the spread of asbestos within the enclosure. Whenever practical, the point of removal should be isolated, enclosed, covered, or shielded from the workers in the area. Waste asbestos containing materials must be bagged during or immediately after removal; the material must remain saturated until the waste container is sealed. Waste material with sharp points or corners must be placed in hard airtight containers rather than bags. Whenever possible, large components should be sealed in plastic sheeting and removed intact. Bags or containers of waste will be removed to the waste holding area, washed, and wrapped in a bag with the appropriate labels. Cleaning the Work Area Surfaces within the work area should be kept free of visible dust and debris to the extent feasible. Whenever visible dust appears on surfaces, the surfaces within the enclosure must be cleaned by wiping with a wet sponge, brush, or cloth and then vacuumed with a HEPA vacuum. All surfaces within the enclosure should be cleaned before the exhaust ventilation system is deactivated and the enclosure is disassembled. An approved encapsulant may be sprayed onto areas after the visible dust has been removed. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. Appendix G.

Substance Technical Information for Asbestos Non-Mandatory I. Substance Identification A. Substance: "Asbestos" is the name of a class of magnesium-silicate minerals that occur in fibrous form. Minerals that are included in this group are chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. B. Asbestos is used in the manufacture of heat-resistant clothing, automotive brake and clutch linings, and a variety of building materials including floor tiles, roofing felts, ceiling tiles, asbestos-cement pipe and sheet, and fire-resistant drywall. Asbestos is also present in pipe and boiler insulation materials, and in sprayed-on materials located on beams, in crawlspaces, and between walls. C. The potential for an asbestos-containing product to release breathable fibers depends on its degree of friability. Friable means that the material can be crumbled with hand pressure and is therefore likely to emit fibers. The fibrous fluffy sprayed-on materials used for fireproofing, insulation, or sound proofing are considered to be friable, and they readily release airborne fibers if disturbed. Materials such as vinyl-asbestos floor tile or roofing felt are considered non-friable if intact and generally do not emit airborne fibers unless subjected to sanding, sawing and other aggressive operations. Asbestos-cement pipe or sheet can emit airborne fibers if the materials are cut or sawed, or if they are broken. D. Permissible exposure: Exposure to airborne asbestos fibers may not exceed 0.1 fibers per cubic centimeter of air (0.1 f/cc) averaged over the 8-hour workday, and 1 fiber per cubic centimeter of air (1.0 f/cc) averaged over a 30 minute work period. II. Health Hazard Data A. Asbestos can cause disabling respiratory disease and various types of cancers if the fibers are inhaled. Inhaling or ingesting fibers from contaminated clothing or skin can also result in these diseases. The symptoms of these diseases generally do not appear for 20 or more years after initial exposure. B. Exposure to asbestos has been shown to cause lung cancer, mesothelioma, and cancer of the stomach and colon. Mesothelioma is a rare cancer of the thin membrane lining of the chest and abdomen. Symptoms of mesothelioma include shortness of breath, pain in the walls of the chest, and/or abdominal pain. III. Respirators and Protective Clothing A. Respirators: You are required to wear a respirator when performing tasks that result in asbestos exposure that exceeds the permissible exposure limit (PEL) of 0.1 f/cc and when performing certain designated operations. Air-purifying respirators equipped with a high-efficiency particulate air (HEPA) filter can be used where airborne asbestos fiber concentrations do not exceed 1.0 f/cc; otherwise, more protective respirators such as air-supplied, positive-pressure, full facepiece respirators must be used. Disposable respirators or dust masks are not permitted to be used for asbestos work. For effective protection, respirators must fit your face and head snugly. Your employer is required to conduct fit tests when you are first assigned a respirator and annually thereafter. Respirators should not be loosened or removed in work situations where their use is required. B. Protective Clothing: You are required to wear protective clothing in work areas where asbestos concentrations exceed the permissible exposure limit (PEL) of 0.1 f/cc. IV. Disposal Procedures and Clean-up A. Wastes that are generated by processes where asbestos is present include: 1. Empty asbestos shipping containers. 2. Process wastes such as cuttings, trimmings, or reject material. 3. Housekeeping waste from wet-sweeping or HEPA-vacuuming. 4. Asbestos fireproofing or insulating material that is removed from buildings. 5. Asbestos-containing building products removed during building renovation or demolition. 6. Contaminated disposable protective clothing. B. Empty shipping bags can be flattened under exhaust hoods and packed into airtight containers for disposal. Empty shipping drums are difficult to clean and should be sealed. C. Vacuum bags or disposable paper filters should not be cleaned, but should be sprayed with a fine water mist and placed into a labeled waste container. D. Process waste and housekeeping waste should be wetted with water or a mixture of water and surfactant prior to packaging in disposable containers. E. Asbestos-containing material that is removed from buildings must be disposed of in leak-tight 6-mil plastic bags, plastic-lined cardboard containers, or plastic-lined metal containers. These wastes, which are removed while wet, should be sealed in containers before they dry out to minimize the release of asbestos fibers during handling. V. Access to Information A. Each year, your employer is required to inform you of the information contained in this standard and appendices for asbestos. In addition, your employer must instruct you in the proper work practices for handling asbestos-containing materials, and the correct use of protective equipment. B. Your employer is required to determine whether you are being exposed to asbestos. Your employer must treat exposure to thermal system insulation and sprayed-on and troweled-on surfacing material as asbestos exposure, unless results of laboratory analysis show that the material does not contain asbestos. You or your representative has the right to observe employee measurements and to record the results obtained. Your employer is required to inform you of your exposure, and, if you are exposed above the permissible exposure limit, he or she is required to inform you of the actions that are being taken to reduce your exposure to within the permissible limit. C. Your employer is required to keep records of your exposures and medical examinations. These exposure records must be kept for at least thirty (30) years, Medical records must be kept for the period of your employment plus thirty (30) years. D. Your employer is required to release your exposure and medical records to your physician or designated representative upon your written request. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. Appendix I. Medical Surveillance Guidelines for Asbestos Non-Mandatory I. Route of Entry: Inhalation, Ingestion II. Toxicology Clinical evidence of the adverse effects associated with exposure to asbestos is present in the form of several well-conducted epidemiological studies of occupationally exposed workers, family contacts of workers, and persons living near asbestos mines. These studies have shown a definite association between exposure to asbestos and an increased incidence of lung cancer, pleural and peritoneal mesothelioma, gastrointestinal cancer, and asbestosis. The latter is a disabling fibrotic lung disease that is caused only by exposure to asbestos. Exposure to asbestos has also been associated with an increased incidence of esophageal, kidney, laryngeal, pharyngeal, and buccal cavity cancers. As with other known chronic occupational diseases, disease associated with asbestos generally appears about 20 years following the first occurrence of exposure. There are no known acute effects associated with exposure to asbestos. Epidemiological studies indicate that the risk of lung cancer among exposed workers who smoke cigarettes is greatly increased over the risk of lung cancer among non-exposed smokers or exposed nonsmokers. These studies suggest that cessation of smoking will reduce the risk of lung cancer for a person exposed to asbestos but will not reduce it to the same level of risk as that existing for an exposed worker who has never smoked. III. Signs and Symptoms of Exposure-Related Disease The signs and symptoms of lung cancer or gastrointestinal cancer induced by exposure to asbestos are not unique, except that a chest X-ray of an exposed patient with lung cancer may show pleural plaques, pleural calcification, or pleural fibrosis. Symptoms characteristic of mesothelioma include shortness of breath, pain in the walls of the chest, or abdominal pain. Mesothelioma has a much longer latency period compared with lung cancer (40 years versus 15-20 years), and mesothelioma is therefore likely to be found among workers who were first exposed to asbestos at an early age. Mesothelioma is always fatal. Asbestosis is pulmonary fibrosis caused by the accumulation of asbestos fibers in the lungs. Symptoms include shortness of breath, coughing, fatigue, and vague feelings of sickness. When the fibrosis worsens, shortness of breath occurs even at rest. The diagnosis of asbestosis is based on a history of exposure to asbestos, the presence of characteristic radiologic changes, end inspiratory crackles (rales), and other clinical features of fibrosing lung disease. Pleural plaques and thickening are observed on X-rays taken during the early stages of the disease. Asbestosis is often a progressive disease even in the absence of continued exposure, although this appears to be a highly individualized characteristic. In severe cases, death may be caused by respiratory or cardiac failure. IV. Surveillance and Preventive Considerations As noted above, exposure to asbestos has been linked to an increased risk of lung cancer, mesothelioma, gastrointestinal cancer, and asbestosis among occupationally exposed workers. Adequate screening tests to determine an employee's potential for developing serious chronic diseases, such as cancer, from exposure to asbestos do not presently exist. However, some tests, particularly chest X-rays and pulmonary function tests, may indicate that an employee has been overexposed to asbestos, thus increasing his or her risk of developing exposure-related chronic disease. It is important for the physician to become familiar with the operating conditions in which occupational exposure to asbestos is likely to occur. This is particularly important in evaluating medical and work histories and in conducting physical examinations. When an active employee has been identified as having been overexposed to asbestos, measures taken by the employer to eliminate or mitigate further exposure should also lower the risk of serious long-term consequences. The employer is required to institute a medical surveillance program for all employees who are or will be exposed to asbestos at or above the permissible exposure limit (0.1 fiber per cubic centimeter of air). All examinations and procedures must be performed by or under the supervision of a licensed physician, at a reasonable time and place, and at no cost to the employee. Although broad latitude is given to the physician in prescribing specific tests to be included in the medical surveillance program, the following elements in the routine examination are required: (i) Medical and work histories with special emphasis directed to symptoms of the respiratory system, cardiovascular system, and digestive tract. (ii) Completion of one of the respiratory disease questionnaires contained in Appendix D: Part 1 for the initial examination and part 2 for periodic examinations. (iii) A physical examination including a chest X-ray (at the discretion of the examining physician for construction work) and pulmonary function testing that includes measurement of the employee's forced vital capacity (FVC) and forced expiratory volume at one second (FEV1). (iv) Any laboratory or other test that the examining physician deems by sound medical practice to be necessary or appropriate. The employer is required to make the prescribed tests available at least annually to those employees covered; more often than specified if recommended by the examining physician; and upon termination of employment. The employer is required to provide the physician with the following information: a copy of this standard and appendices; a description of the employee's work assignments as they relate to asbestos exposure; the employee's representative level of exposure to asbestos; a description of any personal protective and respiratory equipment used; and information from previous medical examinations of the affected employee that is not otherwise available to the physician. Making this information available to the physician will aid in the evaluation of the employee's health in relation to assigned duties and fitness to wear personal protective equipment, if required. The employer is required to obtain a written opinion from the examining physician containing the results of the medical examination; the physician's opinion as to whether the employee has any detected medical conditions that would place the employee at an increased risk of exposure-related disease; any recommended limitations on the employee or on the use of personal protective equipment; and a statement that the employee has been informed by the physician of the results of the medical examination and of any medical conditions related to asbestos exposure that require further explanation or treatment. This written opinion must not reveal specific findings or diagnoses unrelated to exposure to asbestos, and a copy of the opinion must be provided to the affected employee.

Polarized Light Microscopy of Asbestos Non-Mandatory Method number: ID-191 Matrix: Bulk Collection Procedure: Collect approximately 1 to 2 grams of each type of material and place into separate 20 mL scintillation vials. Analytical Procedure: A portion of each separate phase is analyzed by gross examination, phase-polar examination, and central stop dispersion microscopy. Commercial manufacturers and products mentioned in this method are for descriptive use only and do not constitute endorsements by USDOL-OSHA. Similar products from other sources may be substituted. 1. Introduction This method describes the collection and analysis of asbestos bulk materials by light microscopy techniques including phase-polar illumination and central-stop dispersion microscopy. Some terms unique to asbestos analysis are defined below: Amphibole: A family of minerals whose crystals are formed by long, thin units which have two thin ribbons of double chain silicate with a brucite ribbon in between. The shape of each unit is similar to an "I beam". Minerals important in asbestos analysis include cummingtonite-grunerite, crocidolite, tremolite-actinolite and anthophyllite. Asbestos: A term for naturally occurring fibrous minerals. Asbestos includes chrysotile, cummingtonite-grunerite asbestos (amosite), anthophyllite asbestos, tremolite asbestos, crocidolite, actinolite asbestos and any of these minerals which have been chemically treated or altered. The precise chemical formulation of each species varies with the location from which it was mined. Nominal compositions are listed: Chrysotile ..... n = 1.550. Amosite ........ n = 1.670 or 1.680. Crocidolite .... n = 1.690. Anthophyllite .. n = 1.605 and 1.620. Tremolite ...... n = 1.605 and 1.620. Actinolite ..... n = 1.620. Asbestos Fiber: A fiber of asbestos meeting the criteria for a fiber. (See section 3.5. of this Appendix) Aspect Ratio: The ratio of the length of a fiber to its diameter usually defined as "length : width", e.g. 3:1. Brucite: A sheet mineral with the composition Mg(OH)(2). Central Stop Dispersion Staining (microscope): This is a dark field microscope technique that images particles using only light refracted by the particle, excluding light that travels through the particle unrefracted. This is usually accomplished with a McCrone objective or other arrangement which places a circular stop with apparent aperture equal to the objective aperture in the back focal plane of the microscope. Cleavage Fragments: Mineral particles formed by the comminution of minerals, especially those characterized by relatively parallel sides and moderate aspect ratio. Differential Counting: The term applied to the practice of excluding certain kinds of fibers from a phase contrast asbestos count because they are not asbestos. Fiber: A particle longer than or equal to 5 m m with a length to width ratio greater than or equal to 3:1. This may include cleavage fragments. (see section 3.5 of this appendix). Phase Contrast: Contrast obtained in the microscope by causing light scattered by small particles to destructively interfere with unscattered light, thereby enhancing the visibility of very small particles and particles with very low intrinsic contrast. Phase Contrast Microscope: A microscope configured with a phase mask pair to create phase contrast. The technique which uses this is called Phase Contrast Microscopy (PCM). Phase-Polar Analysis: This is the use of polarized light in a phase contrast microscope. It is used to see the same size fibers that are visible in air filter analysis. Although fibers finer than 1 m m are visible, analysis of these is inferred from analysis of larger bundles that are usually present. Phase-Polar Microscope: The phase-polar microscope is a phase contrast microscope which has an analyzer, a polarizer, a first order red plate and a rotating phase condenser all in place so that the polarized light image is enhanced by phase contrast. Sealing Encapsulant: This is a product which can be applied, preferably by spraying, onto an asbestos surface which will seal the surface so that fibers cannot be released. Serpentine: A mineral family consisting of minerals with the general composition Mg(3)(Si(2)O(5)(OH)(4) having the magnesium in brucite layer over a silicate layer. Minerals important in asbestos analysis included in this family are chrysotile, lizardite, antigorite. 1.1. History Light microscopy has been used for well over 100 years for the determination of mineral species. This analysis is carried out using specialized polarizing microscopes as well as bright field microscopes. The identification of minerals is an on-going process with many new minerals described each year. The first recorded use of asbestos was in Finland about 2500 B.C. where the material was used in the mud wattle for the wooden huts the people lived in as well as strengthening for pottery. Adverse health aspects of the mineral were noted nearly 2000 years ago when Pliny the Younger wrote about the poor health of slaves in the asbestos mines. Although known to be injurious for centuries, the first modern references to its toxicity were by the British Labor Inspectorate when it banned asbestos dust from the workplace in 1898. Asbestosis cases were described in the literature after the turn of the century. Cancer was first suspected in the mid 1930's and a causal link to mesothelioma was made in 1965. Because of the public concern for worker and public safety with the use of this material, several different types of analysis were applied to the determination of asbestos content. Light microscopy requires a great deal of experience and craft. Attempts were made to apply less subjective methods to the analysis. X-ray diffraction was partially successful in determining the mineral types but was unable to separate out the fibrous portions from the non-fibrous portions. Also, the minimum detection limit for asbestos analysis by X-ray diffraction (XRD) is about 1%. Differential Thermal Analysis (DTA) was no more successful. These provide useful corroborating information when the presence of asbestos has been shown by microscopy; however, neither can determine the difference between fibrous and non-fibrous minerals when both habits are present. The same is true of Infrared Absorption (IR). When electron microscopy was applied to asbestos analysis, hundreds of fibers were discovered present too small to be visible in any light microscope. There are two different types of electron microscope used for asbestos analysis: Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). Scanning Electron Microscopy is useful in identifying minerals. The SEM can provide two of the three pieces of information required to identify fibers by electron microscopy: morphology and chemistry. The third is structure as determined by Selected Area Electron Diffraction - SAED which is performed in the TEM. Although the resolution of the SEM is sufficient for very fine fibers to be seen, accuracy of chemical analysis that can be performed on the fibers varies with fiber diameter in fibers of less than 0.2 m m diameter. The TEM is a powerful tool to identify fibers too small to be resolved by light microscopy and should be used in conjunction with this method when necessary. The TEM can provide all three pieces of information required for fiber identification. Most fibers thicker than 1 m m can adequately be defined in the light microscope. The light microscope remains as the best instrument for the determination of mineral type. This is because the minerals under investigation were first described analytically with the light microscope. It is inexpensive and gives positive identification for most samples analyzed. Further, when optical techniques are inadequate, there is ample indication that alternative techniques should be used for complete identification of the sample. 1.2. Principle Minerals consist of atoms that may be arranged in random order or in a regular arrangement. Amorphous materials have atoms in random order while crystalline materials have long range order. Many materials are transparent to light, at least for small particles or for thin sections. The properties of these materials can be investigated by the effect that the material has on light passing through it. The six asbestos minerals are all crystalline with particular properties that have been identified and cataloged. These six minerals are anisotropic. They have a regular array of atoms, but the arrangement is not the same in all directions. Each major direction of the crystal presents a different regularity. Light photons travelling in each of these main directions will encounter different electrical neighborhoods, affecting the path and time of travel. The techniques outlined in this method use the fact that light traveling through fibers or crystals in different directions will behave differently, but predictably. The behavior of the light as it travels through a crystal can be measured and compared with known or determined values to identify the mineral species. Usually, Polarized Light Microscopy (PLM is performed with strain-free objectives on a bright-field microscope platform. This would limit the resolution of the microscope to about 0.4 m m. Because OSHA requires the counting and identification of fibers visible in phase contrast, the phase contrast platform is used to visualize the fibers with the polarizing elements added into the light path. Polarized light methods cannot identify fibers finer than about 1 m m in diameter even though they are visible. The finest fibers are usually identified by inference from the presence of larger, identifiable fiber bundles. When fibers are present, but not identifiable by light microscopy, use either SEM or TEM to determine the fiber identity. 1.3. Advantages and Disadvantages The advantages of light microcopy are: (a) Basic identification of the materials was first performed by light microscopy and gross analysis. This provides a large base of published information against which to check analysis and analytical technique. (b) The analysis is specific to fibers. The minerals present can exist in asbestiform, fibrous, prismatic, or massive varieties all at the same time. Therefore, bulk methods of analysis such as X-ray diffraction, IR analysis, DTA, etc. are inappropriate where the material is not known to be fibrous. (c) The analysis is quick, requires little preparation time, and can be performed on-site if a suitably equipped microscope is available. The disadvantages are: (a) Even using phase-polar illumination, not all the fibers present may be seen. This is a problem for very low asbestos concentrations where agglomerations or large bundles of fibers may not be present to allow identification by inference. (b) The method requires a great degree of sophistication on the part of the microscopist. An analyst is only as useful as his mental catalog of images. Therefore, a microscopist's accuracy is enhanced by experience. The mineralogical training of the analyst is very important. It is the basis on which subjective decisions are made. (c) The method uses only a tiny amount of material for analysis. This may lead to sampling bias and false results (high or low). This is especially true if the sample is severely inhomogeneous. (d) Fibers may be bound in a matrix and not distinguishable as fibers so identification cannot be made. 1.4. Method Performance 1.4.1. This method can be used for determination of asbestos content from 0 to 100% asbestos. The detection limit has not been adequately determined, although for selected samples, the limit is very low, depending on the number of particles examined. For mostly homogeneous, finely divided samples, with no difficult fibrous interferences, the detection limit is below 1%. For inhomogeneous samples (most samples), the detection limit remains undefined. NIST has conducted proficiency testing of laboratories on a national scale. Although each round is reported statistically with an average, control limits, etc., the results indicate a difficulty in establishing precision especially in the low concentration range. It is suspected that there is significant bias in the low range especially near 1%. EPA tried to remedy this by requiring a mandatory point counting scheme for samples less than 10%. The point counting procedure is tedious, and may introduce significant biases of its own. It has not been incorporated into this method. 1.4.2. The precision and accuracy of the quantitation tests performed in this method are unknown. Concentrations are easier to determine in commercial products where asbestos was deliberately added because the amount is usually more than a few percent. An analyst's results can be "calibrated" against the known amounts added by the manufacturer. For geological samples, the degree of homogeneity affects the precision. 1.4.3. The performance of the method is analyst dependent. The analyst must choose carefully and not necessarily randomly the portions for analysis to assure that detection of asbestos occurs when it is present. For this reason, the analyst must have adequate training in sample preparation, and experience in the location and identification of asbestos in samples. This is usually accomplished through substantial on-the-job training as well as formal education in mineralogy and microscopy. 1.5. Interferences Any material which is long, thin, and small enough to be viewed under the microscope can be considered an interference for asbestos. There are literally hundreds of interferences in workplaces. The techniques described in this method are normally sufficient to eliminate the interferences. An analyst's success in eliminating the interferences depends on proper training. Asbestos minerals belong to two mineral families: the serpentines and the amphiboles. In the serpentine family, the only common fibrous mineral is chrysotile. Occasionally, the mineral antigorite occurs in a fibril habit with morphology similar to the amphiboles. The amphibole minerals consist of a score of different minerals of which only five are regulated by federal standard: amosite, crocidolite, anthophyllite asbestos, tremolite asbestos and actinolite asbestos. These are the only amphibole minerals that have been commercially exploited for their fibrous properties; however, the rest can and do occur occasionally in asbestiform habit. In addition to the related mineral interferences, other minerals common in building material may present a problem for some microscopists: gypsum, anhydrite, brucite, quartz fibers, talc fibers or ribbons, wollastonite, perlite, attapulgite, etc. Other fibrous materials commonly present in workplaces are: fiberglass, mineral wool, ceramic wool, refractory ceramic fibers, kevlar, nomex, synthetic fibers, graphite or carbon fibers, cellulose (paper or wood) fibers, metal fibers, etc. Matrix embedding material can sometimes be a negative interference. The analyst may not be able to easily extract the fibers from the matrix in order to use the method. Where possible, remove the matrix before the analysis, taking careful note of the loss of weight. Some common matrix materials are: vinyl, rubber, tar, paint, plant fiber, cement, and epoxy. A further negative interference is that the asbestos fibers themselves may be either too small to be seen in Phase contrast Microscopy (PCM) or of a very low fibrous quality, having the appearance of plant fibers. The analyst's ability to deal with these materials increases with experience. 1.6. Uses and Occupational Exposure Asbestos is ubiquitous in the environment. More than 40% of the land area of the United States is composed of minerals which may contain asbestos. Fortunately, the actual formation of great amounts of asbestos is relatively rare. Nonetheless, there are locations in which environmental exposure can be severe such as in the Serpentine Hills of California. There are thousands of uses for asbestos in industry and the home. Asbestos abatement workers are the most current segment of the population to have occupational exposure to great amounts of asbestos. If the material is undisturbed, there is no exposure. Exposure occurs when the asbestos-containing material is abraded or otherwise disturbed during maintenance operations or some other activity. Approximately 95% of the asbestos in place in the United States is chrysotile. Amosite and crocidolite make up nearly all the difference. Tremolite and anthophyllite make up a very small percentage. Tremolite is found in extremely small amounts in certain chrysotile deposits. Actinolite exposure is probably greatest from environmental sources, but has been identified in vermiculite containing, sprayed-on insulating materials which may have been certified as asbestos-free. 1.7. Physical and Chemical Properties The nominal chemical compositions for the asbestos minerals were given in Section 1. Compared to cleavage fragments of the same minerals, asbestiform fibers possess a high tensile strength along the fiber axis. They are chemically inert, noncombustible, and heat resistant. Except for chrysotile, they are insoluble in Hydrochloric acid (HCl). Chrysotile is slightly soluble in HCl. Asbestos has high electrical resistance and good sound absorbing characteristics. It can be woven into cables, fabrics or other textiles, or matted into papers, felts, and mats. 1.8. Toxicology (This Section is for Information Only and Should Not Be Taken as OSHA Policy) Possible physiologic results of respiratory exposure to asbestos are mesothelioma of the pleura or peritoneum, interstitial fibrosis, asbestosis, pneumoconiosis, or respiratory cancer. The possible consequences of asbestos exposure are detailed in the NIOSH Criteria Document or in the OSHA Asbestos Standards 29 CFR 1910.1001, 29 CFR 1926.1101, and 29 CFR 1915.1001. 2. Sampling Procedure 2.1. Equipment for sampling (a) Tube or cork borer sampling device (b) Knife (c) 20 mL scintillation vial or similar vial (d) Sealing encapsulant 2.2. Safety Precautions Asbestos is a known carcinogen. Take care when sampling. While in an asbestos-containing atmosphere, a properly selected and fit-tested respirator should be worn. Take samples in a manner to cause the least amount of dust. Follow these general guidelines: (a) Do not make unnecessary dust. (b) Take only a small amount (1 to 2 g). (c) Tightly close the sample container. (d) Use encapsulant to seal the spot where the sample was taken, if necessary. 2.3. Sampling Procedure Samples of any suspect material should be taken from an inconspicuous place. Where the material is to remain, seal the sampling wound with an encapsulant to eliminate the potential for exposure from the sample site. Microscopy requires only a few milligrams of material. The amount that will fill a 20 mL scintillation vial is more than adequate. Be sure to collect samples from all layers and phases of material. If possible, make separate samples of each different phase of the material. This will aid in determining the actual hazard. DO NOT USE ENVELOPES, PLASTIC OR PAPER BAGS OF ANY KIND TO COLLECT SAMPLES. The use of plastic bags presents a contamination hazard to laboratory personnel and to other samples. When these containers are opened, a bellows effect blows fibers out of the container onto everything, including the person opening the container. If a cork-borer type sampler is available, push the tube through the material all the way, so that all layers of material are sampled. Some samplers are intended to be disposable. These should be capped and sent to the laboratory. If a non-disposable cork borer is used, empty the contents into a scintillation vial and send to the laboratory. Vigorously and completely clean the cork borer between samples. 2.4. Shipment Samples packed in glass vials must not touch or they might break in shipment. (a) Seal the samples with a sample seal over the end to guard against tampering and to identify the sample. (b) Package the bulk samples in separate packages from the air samples. They may cross-contaminate each other and will invalidate the results of the air samples. (c) Include identifying paperwork with the samples, but not in contact with the suspected asbestos. (d) To maintain sample accountability, ship the samples by certified mail, overnight express, or hand carry them to the laboratory. 3. Analysis The analysis of asbestos samples can be divided into two major parts: sample preparation and microscopy. Because of the different asbestos uses that may be encountered by the analyst, each sample may need different preparation steps. The choices are outlined below. There are several different tests that are performed to identify the asbestos species and determine the percentage. They will be explained below. 3.1. Safety (a) Do not create unnecessary dust. Handle the samples in HEPA- filter equipped hoods. If samples are received in bags, envelopes or other inappropriate container, open them only in a hood having a face velocity at or greater than 100 fpm. Transfer a small amount to a scintillation vial and only handle the smaller amount. (b) Open samples in a hood, never in the open lab area. (c) Index of refraction oils can be toxic. Take care not to get this material on the skin. Wash immediately with soap and water if this happens. (d) Samples that have been heated in the muffle furnace or the drying oven may be hot. Handle them with tongs until they are cool enough to handle. (e) Some of the solvents used, such as THF (tetrahydrofuran), are toxic and should only be handled in an appropriate fume hood and according to instructions given in the Material Safety Data Sheet (MSDS). 3.2. Equipment (a) Phase contrast microscope with 10x, 16x and 40x objectives, 10x wide-field eyepieces, G-22 Walton-Beckett graticule, Whipple disk, polarizer, analyzer and first order red or gypsum plate, 100 Watt illuminator, rotating position condenser with oversize phase rings, central stop dispersion objective, Kohler illumination and a rotating mechanical stage. (see Figure 1. of this appendix) (b) Stereo microscope with reflected light illumination, transmitted light illumination, polarizer, analyzer and first order red or gypsum plate, and rotating stage. (c) Negative pressure hood for the stereo microscope (d) Muffle furnace capable of 600 deg.C (e) Drying oven capable of 50 - 150 deg.C (f) Aluminum specimen pans (g) Tongs for handling samples in the furnace (h) High dispersion index of refraction oils (Special for dispersion staining.) n = 1.550 n = 1.585 n = 1.590 n = 1.605 n = 1.620 n = 1.670 n = 1.680 n = 1.690 (i) A set of index of refraction oils from about n=1.350 to n=2.000 in n =0.005 increments. (Standard for Becke line analysis.) (j) Glass slides with painted or frosted ends 1x3 inches 1mm thick, precleaned. (k) Cover Slips 22x22 mm, #1 1/2 (l) Paper clips or dissection needles (m) Hand grinder (n) Scalpel with both #10 and #11 blades (o) 0.1 molar HCl (p) Decalcifying solution (Baxter Scientific Products) Ethylenediaminetetraacetic Acid, Tetrasodium 0.7 g/l Sodium Potassium Tartrate 8.0 mg/liter Hydrochloric Acid 99.2 g/liter Sodium Tartrate 0.14 g/liter (q) Tetrahydrofuran (THF) (r) Hotplate capable of 60 deg.C (s) Balance (t) Hacksaw blade (u) Ruby mortar and pestle 3.3. Sample Pre-Preparation Sample preparation begins with pre-preparation which may include chemical reduction of the matrix, heating the sample to dryness or heating in the muffle furnace. The end result is a sample which has been reduced to a powder that is sufficiently fine to fit under the cover slip. Analyze different phases of samples separately, e.g., tile and the tile mastic should be analyzed separately as the mastic may contain asbestos while the tile may not. (a) Wet Samples Samples with a high water content will not give the proper dispersion colors and must be dried prior to sample mounting. Remove the lid of the scintillation vial, place the bottle in the drying oven and heat at 100 deg.C to dryness (usually about 2 h). Samples which are not submitted to the lab in glass must be removed and placed in glass vials or aluminum weighing pans before placing them in the drying oven. (b) Samples With Organic Interference - Muffle Furnace These may include samples with tar as a matrix, vinyl asbestos tile, or any other organic that can be reduced by heating. Remove the sample from the vial and weigh in a balance to determine the weight of the submitted portion. Place the sample in a muffle furnace at 500 deg.C for 1 to 2 h or until all obvious organic material has been removed. Retrieve, cool and weigh again to determine the weight loss on ignition. This is necessary to determine the asbestos content of the submitted sample, because the analyst will be looking at a reduced sample. Note: Heating above 600 deg.C will cause the sample to undergo a structural change which, given sufficient time, will convert the chrysotile to forsterite. Heating even at lower temperatures for 1 to 2 h may have a measurable effect on the optical properties of the minerals. If the analyst is unsure of what to expect, a sample of standard asbestos should be heated to the same temperature for the same length of time so that it can be examined for the proper interpretation. (c) Samples With Organic Interference - THF Vinyl asbestos tile is the most common material treated with this solvent, although, substances containing tar will sometimes yield to this treatment. Select a portion of the material and then grind it up if possible. Weigh the sample and place it in a test tube. Add sufficient THF to dissolve the organic matrix. This is usually about 4 to 5 mL. Remember, THF is highly flammable. Filter the remaining material through a tared silver membrane, dry and weigh to determine how much is left after the solvent extraction. Further process the sample to remove carbonate or mount directly. (d) Samples With Carbonate Interference Carbonate material is often found on fibers and sometimes must be removed in order to perform dispersion microscopy. Weigh out a portion of the material and place it in a test tube. Add a sufficient amount of 0.1 M HCl or decalcifying solution in the tube to react all the carbonate as evidenced by gas formation; i.e., when the gas bubbles stop, add a little more solution. If no more gas forms, the reaction is complete. Filter the material out through a tared silver membrane, dry and weigh to determine the weight lost. 3.4. Sample Preparation Samples must be prepared so that accurate determination can be made of the asbestos type and amount present. The following steps are carried out in the low-flow hood (a low-flow hood has less than 50 fpm flow): (1) If the sample has large lumps, is hard, or cannot be made to lie under a cover slip, the grain size must be reduced. Place a small amount between two slides and grind the material between them or grind a small amount in a clean mortar and pestle. The choice of whether to use an alumina, ruby, or diamond mortar depends on the hardness of the material. Impact damage can alter the asbestos mineral if too much mechanical shock occurs. (Freezer mills can completely destroy the observable crystallinity of asbestos and should not be used). For some samples, a portion of material can be shaved off with a scalpel, ground off with a hand grinder or hack saw blade. The preparation tools should either be disposable or cleaned thoroughly. Use vigorous scrubbing to loosen the fibers during the washing. Rinse the implements with copious amounts of water and air-dry in a dust-free environment. (2) If the sample is powder or has been reduced as in (1) above, it is ready to mount. Place a glass slide on a piece of optical tissue and write the identification on the painted or frosted end. Place two drops of index of refraction medium n=1.550 on the slide. (The medium n=1.550 is chosen because it is the matching index for chrysotile. Dip the end of a clean paper-clip or dissecting needle into the droplet of refraction medium on the slide to moisten it. Then dip the probe into the powder sample. Transfer what sticks on the probe to the slide. The material on the end of the probe should have a diameter of about 3 mm for a good mount. If the material is very fine, less sample may be appropriate. For non-powder samples such as fiber mats, forceps should be used to transfer a small amount of material to the slide. Stir the material in the medium on the slide, spreading it out and making the preparation as uniform as possible. Place a cover-slip on the preparation by gently lowering onto the slide and allowing it to fall "trapdoor" fashion on the preparation to push out any bubbles. Press gently on the cover slip to even out the distribution of particulate on the slide. If there is insufficient mounting oil on the slide, one or two drops may be placed near the edge of the coverslip on the slide. Capillary action will draw the necessary amount of liquid into the preparation. Remove excess oil with the point of a laboratory wiper. Treat at least two different areas of each phase in this fashion. Choose representative areas of the sample. It my be useful to select particular areas or fibers for analysis. This is useful to identify asbestos in severely inhomogeneous samples. When it is determined that amphiboles may be present, repeat the above process using the appropriate high-dispersion oils until an identification is made or all six asbestos minerals have been ruled out. Note that percent determination must be done in the index medium 1.550 because amphiboles tend to disappear in their matching mediums. 3.5. Analytical procedure Note: This method presumes some knowledge of mineralogy and optical petrography. The analysis consists of three parts: The determination of whether there is asbestos present, what type is present and the determination of how much is present. The general flow of the analysis is: (1) Gross examination. (2) Examination under polarized light on the stereo microscope. (3) Examination by phase-polar illumination on the compound phase microscope. (4) Determination of species by dispersion stain. Examination by Becke line analysis may also be used; however, this is usually more cumbersome for asbestos determination. (5) Difficult samples may need to be analyzed by SEM or TEM, or the results from those techniques combined with light microscopy for a definitive identification. Identification of a particle as asbestos requires that it be asbestiform. Description of particles should follow the suggestion of Campbell. (Figure 1 of this appendix) Figure 1. Particle definitions showing mineral growth habits. From the U.S. Bureau of Mines For the purpose of regulation, the mineral must be one of the six minerals covered and must be in the asbestos growth habit. Large specimen samples of asbestos generally have the gross appearance of wood. Fibers are easily parted from it. Asbestos fibers are very long compared with their widths. The fibers have a very high tensile strength as demonstrated by bending without breaking. Asbestos fibers exist in bundles that are easily parted, show longitudinal fine structure and may be tufted at the ends showing "bundle of sticks" morphology. In the microscope some of these properties may not be observable. Amphiboles do not always show striations along their length even when they are asbestos. Neither will they always show tufting. They generally do not show a curved nature except for very long fibers. Asbestos and asbestiform minerals are usually characterized in groups by extremely high aspect ratios (greater than 100:1). While aspect ratio analysis is useful for characterizing populations of fibers, it cannot be used to identify individual fibers of intermediate to short aspect ratio. Observation of many fibers is often necessary to determine whether a sample consists of "cleavage fragments" or of asbestos fibers. Most cleavage fragments of the asbestos minerals are easily distinguishable from true asbestos fibers. This is because true cleavage fragments usually have larger diameters than 1 m m. Internal structure of particles larger than this usually shows them to have no internal fibrillar structure. In addition, cleavage fragments of the monoclinic amphiboles show inclined extinction under crossed polars with no compensator. Asbestos fibers usually show extinction at zero degrees or ambiguous extinction if any at all. Morphologically, the larger cleavage fragments are obvious by their blunt or stepped ends showing prismatic habit. Also, they tend to be circular rather than filiform. Where the particles are less than 1 m m in diameter and have an aspect ratio greater than or equal to 3:1, it is recommended that the sample be analyzed by SEM or TEM if there is any question whether the fibers are cleavage fragments or asbestiform particles. Care must be taken when analyzing by electron microscopy because the interferences are different from those in light microscopy and may structurally be very similar to asbestos. The classic interference is between anthophyllite and biopyribole or intermediate fiber. Use the same morphological clues for electron microscopy as are used for light microscopy, e.g. fibril splitting, internal longitudinal striation, fraying, curvature, etc. (1) Gross examination: Examine the sample, preferably in the glass vial. Determine the presence of any obvious fibrous component. Estimate a percentage based on previous experience and current observation. Determine whether any prepreparation is necessary. Determine the number of phases present. This step may be carried out or augmented by observation at 6 to 40 x under a stereo microscope. (2) After performing any necessary pre-preparation, prepare slides of each phase as described above. Two preparations of the same phase in the same index medium can be made side-by-side on the same glass for convenience. Examine with the polarizing stereo microscope. Estimate the percentage of asbestos based on the amount of birefringent fiber present. (3) Examine the slides on the phase-polar microscopes at magnifications of 160 and 400x. Note the morphology of the fibers. Long, thin, very straight fibers with little curvature are indicative of fibers from the amphibole family. Curved, wavy fibers are usually indicative of chrysotile. Estimate the percentage of asbestos on the phase-polar microscope under conditions of crossed polars and a gypsum plate. Fibers smaller than 1.0 m m in thickness must be identified by inference to the presence of larger, identifiable fibers and morphology. If no larger fibers are visible, electron microscopy should be performed. At this point, only a tentative identification can be made. Full identification must be made with dispersion microscopy. Details of the tests are included in the appendices. (4) Once fibers have been determined to be present, they must be identified. Adjust the microscope for dispersion mode and observe the fibers. The microscope has a rotating stage, one polarizing element, and a system for generating dark-field dispersion microscopy (see Section 4.6. of this appendix). Align a fiber with its length parallel to the polarizer and note the color of the Becke lines. Rotate the stage to bring the fiber length perpendicular to the polarizer and note the color. Repeat this process for every fiber or fiber bundle examined. The colors must be consistent with the colors generated by standard asbestos reference materials for a positive identification. In n=1.550, amphiboles will generally show a yellow to straw-yellow color indicating that the fiber indices of refraction are higher than the liquid. If long, thin fibers are noted and the colors are yellow, prepare further slides as above in the suggested matching liquids listed below: Type of asbestos .. Index of refraction Chrysotile ........ n = 1.550. Amosite ........... n = 1.670 or 1.680. Crocidolite ....... n = 1.690. Anthophyllite ..... n = 1.605 and 1.620. Tremolite ......... n = 1.605 and 1.620. Actinolite ........ n = 1.620. Where more than one liquid is suggested, the first is preferred; however, in some cases this liquid will not give good dispersion color. Take care to avoid interferences in the other liquid; e.g., wollastonite in n=1.620 will give the same colors as tremolite. In n =1.605 wollastonite will appear yellow in all directions. Wollastonite may be determined under crossed polars as it will change from blue to yellow as it is rotated along its fiber axis by tapping on the cover slip. Asbestos minerals will not change in this way. Determination of the angle of extinction may, when present, aid in the determination of anthophyllite from tremolite. True asbestos fibers usually have 0 deg. extinction or ambiguous extinction, while cleavage fragments have more definite extinction. Continue analysis until both preparations have been examined and all present species of asbestos are identified. If there are no fibers present, or there is less than 0.1% present, end the analysis with the minimum number of slides (2). (5) Some fibers have a coating on them which makes dispersion microscopy very difficult or impossible. Becke line analysis or electron microscopy may be performed in those cases. Determine the percentage by light microscopy. TEM analysis tends to overestimate the actual percentage present. (6) Percentage determination is an estimate of occluded area, tempered by gross observation. Gross observation information is used to make sure that the high magnification microscopy does not greatly over-or under-estimate the amount of fiber present. This part of the analysis requires a great deal of experience. Satisfactory models for asbestos content analysis have not yet been developed, although some models based on metallurgical grain-size determination have found some utility. Estimation is more easily handled in situations where the grain sizes visible at about 160x are about the same and the sample is relatively homogeneous. View all of the area under the cover slip to make the percentage determination. View the fields while moving the stage, paying attention to the clumps of material. These are not usually the best areas to perform dispersion microscopy because of the interference from other materials. But, they are the areas most likely to represent the accurate percentage in the sample. Small amounts of asbestos require slower scanning and more frequent analysis of individual fields. Report the area occluded by asbestos as the concentration. This estimate does not generally take into consideration the difference in density of the different species present in the sample. For most samples this is adequate. Simulation studies with similar materials must be carried out to apply microvisual estimation for that purpose and is beyond the scope of this procedure. (7) Where successive concentrations have been made by chemical or physical means, the amount reported is the percentage of the material in the "as submitted" or original state. The percentage determined by microscopy is multiplied by the fractions remaining after pre-preparation steps to give the percentage in the original sample. For example: Step 1. 60% remains after heating at 550 deg.C for 1 h. Step 2. 30% of the residue of step 1 remains after dissolution of carbonate in 0.1 m HCl. Step 3. Microvisual estimation determines that 5% of the sample is chrysotile asbestos. The reported result is: R = (Microvisual result in percent) x (Fraction remaining after step 2) x (Fraction remaining of original sample after step 1) R = (5) x (.30) x (.60) = 0.9% (8) Report the percent and type of asbestos present. For samples where asbestos was identified, but is less than 1.0%, report "Asbestos present, less than 1.0%." There must have been at least two observed fibers or fiber bundles in the two preparations to be reported as present. For samples where asbestos was not seen, report as "None Detected." Auxiliary Information Because of the subjective nature of asbestos analysis, certain concepts and procedures need to be discussed in more depth. This information will help the analyst understand why some of the procedures are carried out the way they are. 4. 1. Light Light is electromagnetic energy. It travels from its source in packets called quanta. It is instructive to consider light as a plane wave. The light has a direction of travel. Perpendicular to this and mutually perpendicular to each other, are two vector components. One is the magnetic vector and the other is the electric vector. We shall only be concerned with the electric vector. In this description, the interaction of the vector and the mineral will describe all the observable phenomena. From a light source such a microscope illuminator, light travels in all different direction from the filament. In any given direction away from the filament, the electric vector is perpendicular to the direction of travel of a light ray. While perpendicular, its orientation is random about the travel axis. If the electric vectors from all the light rays were lined up by passing the light through a filter that would only let light rays with electric vectors oriented in one direction pass, the light would then be POLARIZED. Polarized light interacts with matter in the direction of the electric vector. This is the polarization direction. Using this property it is possible to use polarized light to probe different materials and identify them by how they interact with light. The speed of light in a vacuum is a constant at about 2.99 x 10(8) m/s. When light travels in different materials such as air, water, minerals or oil, it does not travel at this speed. It travels slower. This slowing is a function of both the material through which the light is traveling and the wavelength or frequency of the light. In general, the more dense the material, the slower the light travels. Also, generally, the higher the frequency, the slower the light will travel. The ratio of the speed of light in a vacuum to that in a material is called the index of refraction (n). It is usually measured at 589 nm (the sodium D line). If white light (light containing all the visible wavelengths) travels through a material, rays of longer wavelengths will travel faster than those of shorter wavelengths, this separation is called dispersion. Dispersion is used as an identifier of materials as described in Section 4.6. 4.2. Material Properties Materials are either amorphous or crystalline. The difference between these two descriptions depends on the positions of the atoms in them. The atoms in amorphous materials are randomly arranged with no long range order. An example of an amorphous material is glass. The atoms in crystalline materials, on the other hand, are in regular arrays and have long range order. Most of the atoms can be found in highly predictable locations. Examples of crystalline material are salt, gold, and the asbestos minerals. It is beyond the scope of this method to describe the different types of crystalline materials that can be found, or the full description of the classes into which they can fall. However, some general crystallography is provided below to give a foundation to the procedures described. With the exception of anthophyllite, all the asbestos minerals belong to the monoclinic crystal type. The unit cell is the basic repeating unit of the crystal and for monoclinic crystals can be described as having three unequal sides, two 90 deg. angles and one angle not equal to 90 deg.. The orthorhombic group, of which anthophyllite is a member has three unequal sides and three 90 deg. angles. The unequal sides are a consequence of the complexity of fitting the different atoms into the unit cell. Although the atoms are in a regular array, that array is not symmetrical in all directions. There is long range order in the three major directions of the crystal. However, the order is different in each of the three directions. This has the effect that the index of refraction is different in each of the three directions. Using polarized light, we can investigate the index of refraction in each of the directions and identify the mineral or material under investigation. The indices alpha, beta, and gamma are used to identify the lowest, middle, and highest index of refraction respectively. The x direction, associated with alpha is called the fast axis. Conversely, the z direction is associated with gamma and is the slow direction. Crocidolite has alpha along the fiber length making it "length-fast". The remainder of the asbestos minerals have the gamma axis along the fiber length. They are called "length-slow". This orientation to fiber length is used to aid in the identification of asbestos. 4.3. Polarized Light Technique Polarized light microscopy as described in this section uses the phase-polar microscope described in Section 3.2. A phase contrast microscope is fitted with two polarizing elements, one below and one above the sample. The polarizers have their polarization directions at right angles to each other. Depending on the tests performed, there may be a compensator between these two polarizing elements. A compensator is a piece of mineral with known properties that "compensates" for some deficiency in the optical train. Light emerging from a polarizing element has its electric vector pointing in the polarization direction of the element. The light will not be subsequently transmitted through a second element set at a right angle to the first element. Unless the light is altered as it passes from one element to the other, there is no transmission of light. 4.4. Angle of Extinction Crystals which have different crystal regularity in two or three main directions are said to be anisotropic. They have a different index of refraction in each of the main directions. When such a crystal is inserted between the crossed polars, the field of view is no longer dark but shows the crystal in color. The color depends on the properties of the crystal. The light acts as if it travels through the crystal along the optical axes. If a crystal optical axis were lined up along one of the polarizing directions (either the polarizer or the analyzer) the light would appear to travel only in that direction, and it would blink out or go dark. The difference in degrees between the fiber direction and the angle at which it blinks out is called the angle of extinction. When this angle can be measured, it is useful in identifying the mineral. The procedure for measuring the angle of extinction is to first identify the polarization direction in the microscope. A commercial alignment slide can be used to establish the polarization directions or use anthophyllite or another suitable mineral. This mineral has a zero degree angle of extinction and will go dark to extinction as it aligns with the polarization directions. When a fiber of anthophyllite has gone to extinction, align the eyepiece reticle or graticule with the fiber so that there is a visual cue as to the direction of polarization in the field of view. Tape or otherwise secure the eyepiece in this position so it will not shift. After the polarization direction has been identified in the field of view, move the particle of interest to the center of the field of view and align it with the polarization direction. For fibers, align the fiber along this direction. Note the angular reading of the rotating stage. Looking at the particle, rotate the stage until the fiber goes dark or "blinks out". Again note the reading of the stage. The difference in the first reading and the second is an angle of extinction. The angle measured may vary as the orientation of the fiber changes about its long axis. Tables of mineralogical data usually report the maximum angle of extinction. Asbestos forming minerals, when they exhibit an angle of extinction, usually do show an angle of extinction close to the reported maximum, or as appropriate depending on the substitution chemistry. 4.5. Crossed Polars with Compensator When the optical axes of a crystal are not lined up along one of the polarizing directions (either the polarizer or the analyzer) part of the light travels along one axis and part travels along the other visible axis. This is characteristic of birefringent materials. The color depends on the difference of the two visible indices of refraction and the thickness of the crystal. The maximum difference available is the difference between the alpha and the gamma axes. This maximum difference is usually tabulated as the birefringence of the crystal. For this test, align the fiber at 45 deg. to the polarization directions in order to maximize the contribution to each of the optical axes. The colors seen are called retardation colors. They arise from the recombination of light which has traveled through the two separate directions of the crystal. One of the rays is retarded behind the other since the light in that direction travels slower. On recombination, some of the colors which make up white light are enhanced by constructive interference and some are suppressed by destructive interference. The result is a color dependent on the difference between the indices and the thickness of the crystal. The proper colors, thicknesses, and retardations are shown on a Michel-Levy chart. The three items, retardation, thickness and birefringence are related by the following relationship: R = t (n gamma - n alpha) R = retardation, t = crystal thickness in m m, and n alpha, gamma = indices of refraction. Examination of the equation for asbestos minerals reveals that the visible colors for almost all common asbestos minerals and fiber sizes are shades of gray and black. The eye is relatively poor at discriminating different shades of gray. It is very good at discriminating different colors. In order to compensate for the low retardation, a compensator is added to the light train between the polarization elements. The compensator used for this test is a gypsum plate of known thickness and birefringence. Such a compensator when oriented at 45 deg. to the polarizer direction, provides a retardation of 530 nm of the 530 nm wavelength color. This enhances the red color and gives the background a characteristic red to red-magenta color. If this "full-wave" compensator is in place when the asbestos preparation is inserted into the light train, the colors seen on the fibers are quite different. Gypsum, like asbestos has a fast axis and a slow axis. When a fiber is aligned with its fast axis in the same direction as the fast axis of the gypsum plate, the ray vibrating in the slow direction is retarded by both the asbestos and the gypsum. This results in a higher retardation than would be present for either of the two minerals. The color seen is a second order blue. When the fiber is rotated 90 deg. using the rotating stage, the slow direction of the fiber is now aligned with the fast direction of the gypsum and the fast direction of the fiber is aligned with the slow direction of the gypsum. Thus, one ray vibrates faster in the fast direction of the gypsum, and slower in the slow direction of the fiber; the other ray will vibrate slower in the slow direction of the gypsum and faster in the fast direction of the fiber. In this case, the effect is subtractive and the color seen is a first order yellow. As long as the fiber thickness does not add appreciably to the color, the same basic colors will be seen for all asbestos types except crocidolite. In crocidolite the colors will be weaker, may be in the opposite directions, and will be altered by the blue absorption color natural to crocidolite. Hundreds of other materials will give the same colors as asbestos, and therefore, this test is not definitive for asbestos. The test is useful in discriminating against fiberglass or other amorphous fibers such as some synthetic fibers. Certain synthetic fibers will show retardation colors different than asbestos; however, there are some forms of polyethylene and aramid which will show morphology and retardation colors similar to asbestos minerals. This test must be supplemented with a positive identification test when birefringent fibers are present which cannot be excluded by morphology. This test is relatively ineffective for use on fibers less than 1 m m in diameter. For positive confirmation TEM or SEM should be used if no larger bundles or fibers are visible. 4.6. Dispersion Staining Dispersion microscopy or dispersion staining is the method of choice for the identification of asbestos in bulk materials. Becke line analysis is used by some laboratories and yields the same results as does dispersion staining for asbestos and can be used in lieu of dispersion staining. Dispersion staining is performed on the same platform as the phase-polar analysis with the analyzer and compensator removed. One polarizing element remains to define the direction of the light so that the different indices of refraction of the fibers may be separately determined. Dispersion microscopy is a dark-field technique when used for asbestos. Particles are imaged with scattered light. Light which is unscattered is blocked from reaching the eye either by the back field image mask in a McCrone objective or a back field image mask in the phase condenser. The most convenient method is to use the rotating phase condenser to move an oversized phase ring into place. The ideal size for this ring is for the central disk to be just larger than the objective entry aperture as viewed in the back focal plane. The larger the disk, the less scattered light reaches the eye. This will have the effect of diminishing the intensity of dispersion color and will shift the actual color seen. The colors seen vary even on microscopes from the same manufacturer. This is due to the different bands of wavelength exclusion by different mask sizes. The mask may either reside in the condenser or in the objective back focal plane. It is imperative that the analyst determine by experimentation with asbestos standards what the appropriate colors should be for each asbestos type. The colors depend also on the temperature of the preparation and the exact chemistry of the asbestos. Therefore, some slight differences from the standards should be allowed. This is not a serious problem for commercial asbestos uses. This technique is used for identification of the indices of refraction for fibers by recognition of color. There is no direct numerical readout of the index of refraction. Correlation of color to actual index of refraction is possible by referral to published conversion tables. This is not necessary for the analysis of asbestos. Recognition of appropriate colors along with the proper morphology are deemed sufficient to identify the commercial asbestos minerals. Other techniques including SEM, TEM, and XRD may be required to provide additional information in order to identify other types of asbestos Make a preparation in the suspected matching high dispersion oil, e.g., n=1.550 for chrysotile. Perform the preliminary tests to determine whether the fibers are birefringent or not. Take note of the morphological character. Wavy fibers are indicative of chrysotile while long, straight, thin, frayed fibers are indicative of amphibole asbestos. This can aid in the selection of the appropriate matching oil. The microscope is set up and the polarization direction is noted as in Section 4.4. Align a fiber with the polarization direction. Note the color. This is the color parallel to the polarizer. Then rotate the fiber rotating the stage 90 deg. so that the polarization direction is across the fiber. This is the perpendicular position. Again note the color. Both colors must be consistent with standard asbestos minerals in the correct direction for a positive identification of asbestos. If only one of the colors is correct while the other is not, the identification is not positive. If the colors in both directions are bluish-white, the analyst has chosen a matching index oil which is higher than the correct matching oil, e.g. the analyst has used n=1.620 where chrysotile is present. The next lower oil (Section 3.5.) should be used to prepare another specimen. If the color in both directions is yellow-white to straw-yellow-white, this indicates that the index of the oil is lower than the index of the fiber, e.g. the preparation is in n=1.550 while anthophyllite is present. Select the next higher oil (Section 3.5.) and prepare another slide. Continue in this fashion until a positive identification of all asbestos species present has been made or all possible asbestos species have been ruled out by negative results in this test. Certain plant fibers can have similar dispersion colors as asbestos. Take care to note and evaluate the morphology of the fibers or remove the plant fibers in pre-preparation. Coating material on the fibers such as carbonate or vinyl may destroy the dispersion color. Usually, there will be some outcropping of fiber which will show the colors sufficient for identification. When this is not the case, treat the sample as described in Section 3.3. and then perform dispersion staining. Some samples will yield to Becke line analysis if they are coated or electron microscopy can be used for identification. 5. References 5.1.

(1) When local exhaust ventilation is used, the system (including exhaust fans, jets, ducts, hoods, separators, and all necessary appurtenances) shall be designed, constructed, installed, inspected, tested, maintained, and operated so as to ensure the required protection by maintaining a volume and velocity of exhaust air sufficient to gather dusts, fumes, mists, vapors, or gases from the equipment or processes, and to convey them to suitable points of safe disposal, thereby preventing their dispersion in harmful quantities into the atmosphere of work rooms or other places where persons are employed. (2) When general mechanical ventilation is used, the volume and distribution of air shall be sufficient to dilute airborne contaminant concentrations in employees' breathing zones to safe levels. (b) Duration of Operations. The exhaust system shall be in operation continually during all operations for which it is designed. The system shall continue to operate some time after the cessation of said operations, the length of time to depend upon the individual circumstances and effectiveness of the ventilation system. (c) Disposal of Exhaust Materials. (1) The air outlet from every dust separator/collector and the dusts, fumes, mists, vapors or gases collected by an exhaust or ventilating system shall discharge to the outside atmosphere, provided that the exhaust system shall discharge to the outer air in such a manner that it will not cause a harmful exposure in any accessible workplace. Collecting systems which return air to work areas may be used if contaminants which accumulate in the work area air do not result in harmful exposure to employees. (2) The air exhausted from blast-cleaning equipment, grinding, buffing, polishing equipment and all other equipment requiring exhausting of dust or particulate shall be discharged through dust-collecting equipment. Dust and refuse discharged from an exhaust system shall be disposed of in such a manner that it will not result in harmful exposure to employees. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1531. Respiratory Protective Equipment. Note: The requirements applicable to construction work under this section are identical to those set forth in section 5144. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1532. Cadmium. (a) Scope. This standard applies to all occupational exposures to cadmium and cadmium compounds, in all forms, in all construction work where an employee may potentially be exposed to cadmium. Construction work is defined as work involving construction, alteration and/or repair, including but not limited to the following: (1) wrecking, demolition or salvage of structures where cadmium or materials containing cadmium are present; (2) use of cadmium containing-paints and cutting, brazing, burning, grinding or welding on surfaces that were painted with cadmium-containing paints; (3) construction, alteration, repair, maintenance, or renovation of structures, substrates, or portions thereof, that contain cadmium, or materials containing cadmium; (4) cadmium welding; cutting and welding cadmium-plated steel; brazing or welding with cadmium alloys; (5) installation of products containing cadmium; (6) electrical grounding with cadmium welding, or electrical work using cadmium-coated conduit; (7) maintaining or retrofitting cadmium-coated equipment; (8) cadmium contamination/emergency cleanup; and (9) transportation, disposal, storage, or containment of cadmium or materials containing cadmium on the site or location at which construction activities are performed. (b) Definitions. Action level (AL) is defined as an airborne concentration of cadmium of 2.5 micrograms per cubic meter of air (2.5<>g/m [FN3]), calculated as an 8- hour time-weighted average (TWA). Authorized person means any person authorized by the employer and required by work duties to be present in regulated areas or any person authorized by the Chief to be in regulated areas. Chief means the Chief of the Division of Occupational Safety and Health, or designee. Competent person, in accordance with section 1504, means a person designated by the employer to act on the employer's behalf who is capable of identifying existing and potential cadmium hazards in the workplace and the proper methods to control them in order to protect workers, and has the authority necessary to take prompt corrective measures to eliminate or control such hazards. The duties of a competent person include at least the following: determining prior to the performance of work whether cadmium is present in the workplace; establishing, where necessary, regulated areas and assuring that access to and from those areas is limited to authorized employees; assuring the adequacy of any employee exposure monitoring required by this standard; assuring that all employees exposed to air cadmium levels above the PEL wear appropriate personal protective equipment and are trained in the use of appropriate methods of exposure control; assuring that proper hygiene facilities are provided and that workers are trained to use those facilities; and assuring that the engineering controls required by this standard are implemented, maintained in proper operating condition, and functioning properly. Emergency means any occurrence such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment which results in an unexpected and potentially hazardous release of Cadmium. Employee exposure and similar language referring to the air cadmium level to which an employee is exposed means the exposure to airborne cadmium that would occur if the employee were not using respiratory protective equipment. Final medical determination is the written medical opinion of the employee's health status by the examining physician under subsections (l)(3)-(12) or, if multiple physician review under subsection (l)(13) or the alternative physician determination under subsection (l)(14) is invoked, it is the final, written medical finding, recommendation or determination that emerges from that process. High-efficiency particulate air [HEPA] filter means a filter capable of trapping and retaining at least 99.97 percent of mono-dispersed particles of 0.3 micrometers in diameter. NIOSH means the Director of the National Institute for Occupational Safety and Health (NIOSH), U.S. Department of Health and Human Services, or designee. Regulated area means an area demarcated by the employer where an employee's exposure to airborne concentrations of cadmium exceeds, or can reasonably be expected to exceed the permissible exposure limit (PEL). (c) Permissible Exposure Limit (PEL). The employer shall assure that no employee is exposed to an airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5 <>g/m [FN3]), calculated as an eight-hour time-weighted average exposure (TWA). (d) Exposure Monitoring. (1) General. (A) Prior to the performance of any construction work where employees may be potentially exposed to cadmium, the employer shall establish the applicability of this standard by determining whether cadmium is present in the workplace and whether there is the possibility that employee exposures will be at or above the action level. The employer shall designate a competent person who shall make this determination. Investigation and material testing techniques shall be used, as appropriate, in the determination. Investigation shall include a review of relevant plans, past reports, material safety data sheets, and other available records, and consultations with the property owner and discussions with appropriate individuals and agencies. (B) Where cadmium has been determined to be present in the workplace, and it has been determined that there is a possibility the employee's exposure will be at or above the action level, the competent person shall identify employees potentially exposed to cadmium at or above the action level. (C) Determinations of employee exposure shall be made from breathing-zone air samples that reflect the monitored employee's regular, daily 8-hour TWA exposure to cadmium. (D) Eight-hour TWA exposures shall be determined for each employee on the basis of one or more personal breathing-zone air samples reflecting full shift exposure on each shift, for each job classification, in each work area. Where several employees perform the same job tasks, in the same job classification, on the same shift, in the same work area, and the length, duration, and level of cadmium exposures are similar, an employer may sample a representative fraction of the employees instead of all employees in order to meet this requirement. In representative sampling, the employer shall sample the employee(s) expected to have the highest cadmium exposures. (2) Specific. (A) Initial monitoring. Except as provided for in subsection (d)(2)(C), where a determination conducted under subsection (d)(1)(A) shows the possibility of employee exposure to cadmium at or above the action level, the employer shall conduct exposure monitoring as soon as practicable that is representative of the exposure for each employee in the workplace who is or may be exposed to cadmium at or above the action level. (B) In addition, if the employee periodically performs tasks that may expose the employee to a higher concentration of airborne cadmium, the employee shall be monitored while performing those tasks. (C) Where the employer has objective data, as defined in subsection (n)(2), demonstrating that employee exposure to cadmium will not exceed airborne concentrations at or above the action level under the expected conditions of processing, use, or handling, the employer may rely upon such data instead of implementing initial monitoring. (D) Where a determination conducted under subsections (d)(1) or (d)(2) is made that a potentially exposed employee is not exposed to airborne concentrations of cadmium at or above the action level, the employer shall make a written record of such determination. The record shall include at least the monitoring data developed under subsections (d)(2)(A)-(C), where applicable, and shall also include the date of determination, and the name and social security number of each employee. (3) Monitoring Frequency (periodic monitoring). (A) If the initial monitoring or periodic monitoring reveals employee exposures to be at or above the action level, the employer shall monitor at a frequency and pattern needed to assure that the monitoring results reflect with reasonable accuracy the employee's typical exposure levels, given the variability in the tasks performed, work practices, and environmental conditions on the job site, and to assure the adequacy of respiratory selection and the effectiveness of engineering and work practice controls. (B) If the initial monitoring or the periodic monitoring indicates that employee exposures are below the action level and that result is confirmed by the results of another monitoring taken at least seven days later, the employer may discontinue the monitoring for those employees whose exposures are represented by such monitoring. (4) Additional Monitoring. The employer also shall institute the exposure monitoring required under subsections (d)(2)(A) and (d)(3) whenever there has been a change in the raw materials, equipment, personnel, work practices, or finished products that may result in additional employees being exposed to cadmium at or above the action level or in employees already exposed to cadmium at or above the action level being exposed above the PEL, or whenever the employer or competent person has any reason to suspect that any other change might result in such further exposure. (5) Employee Notification of Monitoring Results. (A) No later than five working days after the receipt of the results of any monitoring performed under this section, the employer shall notify each affected employee individually in writing of the results. In addition, within the same time period, the employer shall post the results of the exposure monitoring in an appropriate location that is accessible to all affected employees. (B) Wherever monitoring results indicate that employee exposure exceeds the PEL, the employer shall include in the written notice a statement that the PEL has been exceeded and a description of the corrective action being taken by the employer to reduce employee exposure to or below the PEL. (6) Accuracy of Measurement. The employer shall use a method of monitoring and analysis that has an accuracy of not less than plus or minus 25 percent (+25%), with a confidence level of 95 percent, for airborne concentrations of cadmium at or above the action level and the permissible exposure limit. (e) Regulated Areas. (1) Establishment. The employer shall establish a regulated area wherever an employee's exposure to airborne concentrations of cadmium is, or can reasonably be expected to be in excess of the permissible exposure limit (PEL). (2) Demarcation. Regulated areas shall be demarcated from the rest of the workplace in any manner that adequately establishes and alerts employees of the boundaries of the regulated area, including employees who are or may be incidentally in the regulated areas, and that protects persons outside the area from exposure to airborne concentrations of cadmium in excess of the PEL. (3) Access. Access to regulated areas shall be limited to authorized persons. (4) Provision of Respirators. Each person entering a regulated area shall be supplied with and required to use a respirator, selected in accordance with subsection (g)(2). (5) Prohibited Activities. The employer shall assure that employees do not eat, drink, smoke, chew tobacco or gum, or apply cosmetics in regulated areas, or carry the products associated with any of these activities into regulated areas or store such products in those areas. (f) Methods of Compliance. (1) Compliance Hierarchy. (A) Except as specified in subsection (f)(1)(B), the employer shall implement engineering and work practice controls to reduce and maintain employee exposure to cadmium at or below the PEL, except to the extent that the employer can demonstrate that such controls are not feasible. (B) The requirement to implement engineering controls to achieve the PEL does not apply where the employer demonstrates the following: 1. the employee is only intermittently exposed; and 2. the employee is not exposed above the PEL on 30 or more days per year (12 consecutive months) (C) Wherever engineering and work practice controls are not sufficient to reduce employee exposure to or below the PEL, the employer nonetheless shall implement such controls to reduce exposures to the lowest levels achievable. The employer shall supplement such controls with respiratory protection that complies with the requirements of subsection (g) and the PEL. (D) The employer shall not use employee rotation as a method of compliance. (2) Specific Operations. (A) Abrasive blasting. Abrasive blasting on cadmium or cadmium-containing materials shall be conducted in a manner that will provide adequate protection. (B) Heating cadmium and cadmium-containing materials. Welding, cutting, and other forms of heating of cadmium or cadmium-containing materials shall be conducted in accordance with the requirements of sections 1536 and 1537, where applicable. (3) Prohibitions. (A) High speed abrasive disc saws and similar abrasive power equipment shall not be used for work on cadmium or cadmium-containing materials unless they are equipped with appropriate engineering controls to minimize emissions, if the exposure levels are above the PEL. (B) Materials containing cadmium shall not be applied by spray methods, if exposures are above the PEL, unless employees are protected with supplied-air respiratorswith full facepiece, hood, helmet, suit, operated in positive pressure mode and measures are instituted to limit overspray and prevent contamination of adjacent areas. (4) Mechanical Ventilation. (A) When ventilation is used to control exposure, measurements that demonstrate the effectiveness of the system in controlling exposure, such as capture velocity, duct velocity, or static pressure shall be made as necessary to maintain its effectiveness. (B) Measurements of the system's effectiveness in controlling exposure shall be made as necessary within five working days of any change in production, process, or control that might result in a significant increase in employee exposure to cadmium. (C) Recirculation of air. If air from exhaust ventilation is recirculated into the workplace, the system shall have a high efficiency filter and be monitored to assure effectiveness. (D) Procedures shall be developed and implemented to minimize employee exposure to cadmium when maintenance of ventilation systems and changing of filters is being conducted. (5) Compliance Program. (A) Where employee exposure to cadmium exceeds the PEL and the employer is required under subsection (f)(1) to implement controls to comply with the PEL prior to the commencement of the job, the employer shall establish and implement a written compliance program to reduce employee exposure to or below the PEL. To the extent that engineering and work practice controls cannot reduce exposures to or below the PEL, the employer shall include in the written compliance program the use of appropriate respiratory protection to achieve compliance with the PEL. (B) Written compliance programs shall be reviewed and updated as often and as promptly as necessary to reflect significant changes in the employer's compliance status or significant changes in the lowest air cadmium level that is technologically feasible. (C) A competent person shall review the comprehensive compliance program initially and after each change. (D) Written compliance programs shall be provided upon request for examination and copying to the Chief, NIOSH, affected employees, and designated employee representatives. (g) Respiratory Protection. (1) General. For employees who use respirators required by this section, the employer must provide respirators that comply with the requirements of this subsection. Respirators must be used during: (A) Periods necessary to install or implement feasible engineering and work practice controls when employee exposures exceed the PEL; (B) Maintenance and repair activities and during those brief or intermittent operations where exposures exceed the PEL and engineering and work practice controls are not feasible, or are not required; (C) Work operations in the regulated areas specified in subsection (e); (D) Work operations for which the employer has implemented all feasible engineering and work practice controls and such controls are not sufficient to reduce exposures to or below the PEL; (E) Emergencies; (F) Work operations for which an employee who is exposed to cadmium at or above the action level requests a respirator; and (G) Work operations for which engineering controls are not required under subsection (f)(1)(B) to reduce employee exposures that exceed the PEL. (2) Respirator program. (A) The employer must implement a respiratory protection program in accordance with section 5144(b) (except (d)(1)(C)) through (m). (B) If an employee exhibits breathing difficulty during fit testing or respirator use, the employer must provide the employee with a medical examination in accordance with subsection (l)(6)(B) to determine if the employee can use a respirator while performing the required duties. (C) No employee must use a respirator when, based on their most recent medical examination, the examining physician determines that the employee will be unable to function normally while using a respirator. If the physician determines the employee must be limited in, or removed from, their current job because of the employee's inability to use a respirator, the job limitation or removal must be conducted in accordance with subsections (l)(11) and (12). (3) Respirator Selection. (A) The employer must select the appropriate respirator from Table 1 of this section.

Previously exposed - The employer shall also institute a medical surveillance program for all employees who might previously have been exposed to cadmium by the employer prior to the effective date of this standard in tasks specified under subsection (l)(1)(A)1., unless the employer demonstrates that the employee did not in the years prior to the effective date of this section work in those tasks for the employer with exposure to cadmium for an aggregated total of more than 12 months. (B) To determine an employee's fitness for using a respirator, the employer shall provide the limited medical examination specified in subsection (l)(6). (C) The employer shall assure that all medical examinations and procedures required by this section are performed by or under the supervision of a licensed physician, who has read and is familiar with the health effects section of Appendix A, the regulatory text of this section, the protocol for sample handling and lab selection in Appendix F, and the questionnaire of Appendix D. (D) The employer shall provide the medical surveillance required by this section, including multiple physician review under subsection (l)(13) without cost to employees, and at a time and place that is reasonable and convenient to employees. (E) The employer shall assure that the collecting and handling of biological samples of cadmium in urine (CdU), cadmium in blood (CdB), and beta-2 microglobulin in urine (<>2-M) taken from employees under this section is done in a manner that assures their reliability and that analysis of biological samples of cadmium in urine (CdU), cadmium in blood (CdB), and beta-2 microglobulin in urine (<>2-M) taken from employees under this section is performed in laboratories with demonstrated proficiency to perform the particular analysis. (See Appendix F.) (2) Initial Examination. (A) For employees covered by medical surveillance under subsection (l)(1)(A), the employer shall provide an initial medical examination. The examination shall be provided to those employees within 30 days after initial assignment to a job with exposure to cadmium or no later than 90 days after the effective date of this section, whichever date is later. (B) The initial medical examination shall include: 1. A detailed medical and work history, with emphasis on: past, present, and anticipated future exposure to cadmium; any history of renal, cardiovascular, respiratory, hematopoietic, reproductive, and/or musculo-skeletal system dysfunction; current usage of medication with potential nephrotoxic side-effects; and smoking history and current status; and 2. Biological monitoring that includes the following tests: a. Cadmium in urine (CdU), standardized to grams of creatinine (g/Cr); b. Beta-2 microglobulin in urine (<>2-M), standardized to grams of creatinine (g/Cr), with pH specified, as described in Appendix F; and c. Cadmium in blood (CdB), standardized to liters of whole blood (lwb). (C) Recent Examination: An initial examination is not required to be provided if adequate records show that the employee has been examined in accordance with the requirements of subsection (l)(2)(B) within the past 12 months. In that case, such records shall be maintained as part of the employee's medical record and the prior exam shall be treated as if it were an initial examination for the purposes of subsections (l)(3) and (4). (3) Actions Triggered by Initial Biological Monitoring: (A) If the results of the biological monitoring tests in the initial examination show the employee's CdU level to be at or below 3<>g/g Cr,<< beta>>2-M level to be at or below 300<>g/g Cr and CdB level to be at or below 5<>g/lwb, then: 1. for employees who are subject to medical surveillance under subsections (l)(1)(A)1. because of current or anticipated exposure to cadmium, the employer shall provide the minimum level of periodic medical surveillance in accordance with the requirements in subsection (l)(4)(A); and 2. for employees who are subject to medical surveillance under subsection (l)(1)(A)2. because of prior but not current exposure, the employer shall provide biological monitoring for CdU, <>2-M, and CdB one year after the initial biological monitoring and then the employer shall comply with the requirements of subsection (l)(4)(F). (B) For all employees who are subject to medical surveillance under subsection (l)(1)(A), if the results of the initial biological monitoring tests show the level of CdU to exceed 3<>g/g Cr, the level of<>2-M to be in excess of 300<>g/g Cr, or the level of CdB to be in excess of 5mg/lwb, the employer shall: 1. within two weeks after receipt of biological monitoring results, reassess the employee's occupational exposure to cadmium as follows: a. reassess the employee's work practices and personal hygiene; b. reevaluate the employee's respirator use, if any, and the respirator program; c. review the hygiene facilities; d. reevaluate the maintenance and effectiveness of the relevant engineering controls; e. assess the employee's smoking history and status; 2. within 30 days after the exposure reassessment, specified in (l)(3)(B)1., take reasonable steps to correct any deficiencies found in the reassessment that may be responsible for the employee's excess exposure to cadmium; and, 3. within 90 days after receipt of biological monitoring results, provide a full medical examination to the employee in accordance with the requirements of subsection (l)(4)(B). After completing the medical examination, the examining physician shall determine in a written medical opinion whether to medically remove the employee. If the physician determines that medical removal is not necessary, then until the employee's CdU level falls to or below 3<>g/g Cr,<>2-M level falls to or below 300mg/g Cr and CdB level falls to or below 5mg/lwb, the employer shall: a. Provide biological monitoring in accordance with subsection (l)(2)(B)2. on a semiannual basis; and b. Provide annual medical examinations in accordance with subsection (l)(4)(B). (C) For all employees who are subject to medical surveillance under subsection (l)(1)(A), if the results of the initial biological monitoring tests show the level of CdU to be in excess of 15<>g/g Cr, or the level of CdB to be in excess of 15mg/lwb, or the level ofb 2-M to be in excess of 1,500<>g/g Cr, the employer shall comply with the requirements of subsections (l)(3)(B)1.- 2.. Within 90 days after receipt of biological monitoring results, the employer shall provide a full medical examination to the employee in accordance with the requirements of subsection (l)(4)(B). After completing the medical examination, the examining physician shall determine in a written medical opinion whether to medically remove the employee. However, if the initial biological monitoring results and the biological monitoring results obtained during the medical examination both show that: CdU exceeds 15<>g/g Cr; or CdB exceeds 15mg/lwb; or<>2-M exceeds 1500<>g/g Cr, and in addition CdU exceeds 3<>g/g Cr or CdB exceeds 5mg/liter of whole blood, then the physician shall medically remove the employee from exposure to cadmium at or above the action level. If the second set of biological monitoring results obtained during the medical examination does not show that a mandatory removal trigger level has been exceeded, then the employee is not required to be removed by the mandatory provisions of this subsection. If the employee is not required to be removed by the mandatory provisions of this subsection or by the physician's determination, then until the employee's CdU level falls to or below 3<>g/g Cr,<>2-M level falls to or below 300<>g/g Cr and CdB level falls to or below 5mg/lwb, the employer shall: 1. Periodically reassess the employee's occupational exposure to cadmium; 2. Provide biological monitoring in accordance with subsection (l)(2)(B)2. on a quarterly basis; and 3. Provide semiannual medical examinations in accordance with subsection (l)(4)(B). (D) For all employees to whom medical surveillance is provided, beginning on January 1, 1999, and in lieu of subsection (l)(3)(C), whenever the results of initial biological monitoring tests show the employee's CdU level to be in excess of 7<>g/g Cr, or<>2-M level to be in excess of 750<>g/g Cr, or CdB level to be in excess of 10mg/lwb, the employer shall comply with the requirements of subsection (l)(3)(B)1.-2.. Within 90 days after receipt of biological monitoring results, the employer shall provide a full medical examination to the employee in accordance with the requirements of subsection (l)(4)(B). After completing the medical examination, the examining physician shall determine in a written medical opinion whether to medically remove the employee. However, if the initial biological monitoring results and the biological monitoring results obtained during the medical examination both show that: CdU exceeds 7<>g/g Cr; or CdB exceeds 10mg/lwb; or<>2-M exceeds 750<>g/g Cr, and in addition CdU exceeds 3<>g/g Cr or CdB exceeds 5mg/liter of whole blood, then the physician shall medically remove the employee from exposure to cadmium at or above the action level. If the second set of biological monitoring results obtained during the medical examination does not show that a mandatory removal trigger level has been exceeded, then the employee is not required to be removed by the mandatory provisions of this subsection. If the employee is not required to be removed by the mandatory provisions of this subsection or by the physician's determination, then until the employee's CdU level falls to or below 3<>g/g Cr, <>2-M level falls to or below 300<>g/g Cr and CdB level falls to or below 5mg/lwb, the employer shall: 1. Periodically reassess the employee's occupational exposure to cadmium; 2. Provide biological monitoring in accordance with subsection (l)(2)(B)2. on a quarterly basis; and 3. Provide semiannual medical examinations in accordance with subsection (l)(4)(B). (4) Periodic Medical Surveillance. (A) For each employee who is covered by medical surveillance under subsection (l)(1)(A)1. because of current or anticipated exposure to cadmium, the employer shall provide at least the minimum level of periodic medical surveillance, which consists of periodic medical examinations and periodic biological monitoring. A periodic medical examination shall be provided within one year after the initial examination required by subsection (l)(2) and thereafter at least biennially. Biological sampling shall be provided at least annually either as part of a periodic medical examination or separately as periodic biological monitoring. (B) The periodic medical examination shall include: 1. A detailed medical and work history, or update thereof, with emphasis on: past, present and anticipated future exposure to cadmium; smoking history and current status; reproductive history; current use of medications with potential nephrotoxic side-effects; any history of renal, cardiovascular, respiratory, hematopoietic, and/or musculo-skeletal system dysfunction; and as part of the medical and work history, for employees who wear respirators, questions 3-11 and 25-32 in Appendix D; 2. A complete physical examination with emphasis on: blood pressure, the respiratory system, and the urinary system; 3. A 14 inch by 17 inch, or a reasonably standard sized posterior-anterior chest X-ray (after the initial X-ray, the frequency of chest X-rays is to be determined by the examining physician); 4. Pulmonary function tests, including forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1); 5. Biological monitoring, as required in subsection (l)(2)(B)2.; 6. Blood analysis, in addition to the analysis required under subsection (l)(2)(B)2., including blood urea nitrogen, complete blood count, and serum creatinine; 7. Urinalysis, in addition to the analysis required under subsection (l)(2)(B)2., including the determination of albumin, glucose, and total and low molecular weight proteins; 8. For males over 40 years old, prostate palpation, or other at least as effective diagnostic test(s), and; 9. Any additional tests or procedures deemed appropriate by the examining physician. (C) Periodic biological monitoring shall be provided in accordance with subsection (l)(2)(B)2.. (D) If the results of periodic biological monitoring or the results of biological monitoring performed as part of the periodic medical examination show the level of the employee's CdU,<>2-M, or CdB to be in excess of the levels specified in subsections (l)(3)(B) or (C); or, beginning on January 1, 1999, in excess of the levels specified in subsection (l)(3)(B) or (D), the employer shall take the appropriate actions specified in subsections (l)(3)(B)- (D), respectively. (E) For previously exposed employees under subsection (l)(1)(A)2.: 1. If the employee's levels of CdU did not exceed 3<>g/g Cr, CdB did not exceed 5mg/lwb, and<>2-M did not exceed 300<>g/g Cr in the initial biological monitoring tests, and if the results of the followup biological monitoring required by subsection (l)(3)(A)2. one year after the initial examination confirm the previous results, the employer may discontinue all periodic medical surveillance for that employee. 2. If the initial biological monitoring results for CdU, CdB, or<>2-M were in excess of the levels specified in (l)(3)(A), but subsequent biological monitoring results required by (l)(3)(B)-(D) show that the employee's CdU levels no longer exceed 3<>g/g Cr, CdB levels no longer exceed 5mg/lwb, and<>2-M levels no longer exceed 300<>g/g Cr, the employer shall provide biological monitoring for CdU, CdB, and<>2-M one year after these most recent biological monitoring results. If the results of the followup biological monitoring, specified in this subsection, confirm the previous results, the employer may discontinue all periodic medical surveillance for that employee. 3. However, if the results of the follow-up tests specified in (l)(4)(E)1. or 2. indicate that the level of the employee's CdU,b 2-M, or CdB exceeds these same levels, the employer is required to provide annual medical examinations in accordance with the provisions of subsection (l)(4)(B) until the results of biological monitoring are consistently below these levels or the examining physician determines in a written medical opinion that further medical surveillance is not required to protect the employee's health. (F) A routine, biennial medical examination is not required to be provided in accordance with subsections (l)(3)(A) and (l)(4) if adequate medical records show that the employee has been examined in accordance with the requirements of subsection (l)(4)(B) within the past 12 months. In that case, such records shall be maintained by the employer as part of the employee's medical record, and the next routine, periodic medical examination shall be made available to the employee within two years of the previous examination. (5) Actions Triggered by Medical Examinations: (A) If the results of a medical examination carried out in accordance with this section indicate any laboratory or clinical finding consistent with cadmium toxicity that does not require employer action under subsections (l)(2), (3) or (4), the employer shall take the following steps and continue to take them until the physician determines that they are no longer necessary. 1. Periodically reassess: the employee's work practices and personal hygiene; the employee's respirator use, if any; the employee's smoking history and status; the respiratory protection program; the hygiene facilities; the maintenance and effectiveness of the relevant engineering controls; and take all reasonable steps to correct the deficiencies found in the reassessment that may be responsible for the employee's excess exposure to cadmium. 2. Provide semi-annual medical reexaminations to evaluate the abnormal clinical sign(s) of cadmium toxicity until the results are normal or the employee is medically removed; and 3. Where the results of tests for total proteins in urine are abnormal, provide a more detailed medical evaluation of the toxic effects of cadmium on the employee's renal system. (6) Examination for Respirator Use: (A) To determine an employee's fitness for respirator use, the employer shall provide a medical examination that includes the elements specified in (l)(6)(A)1.-4.. This examination shall be provided prior to the employee's being assigned to a job that requires the use of a respirator or no later than 90 days after this section goes into effect, whichever date is later, to any employee without a medical examination within the preceding 12 months that satisfies the requirements of this subsection. 1. A detailed medical and work history, or update thereof, with emphasis on: past exposure to cadmium; smoking history and current status; any history of renal, cardiovascular, respiratory, hematopoietic, and/or musculo-skeletal system dysfunction; a description of the job for which the respirator is required; and questions 3-11 and 25-32 in Appendix D; 2. A blood pressure test; 3. Biological monitoring of the employee's levels of CdU, CdB and<>2-M in accordance with the requirements of subsection (l)(2)(B)2., unless such results already have been obtained within the twelve months; and 4. Any other test or procedure that the examining physician deems appropriate. (B) After reviewing all the information obtained from the medical examination required in subsection (l)(6)(A), the physician shall determine whether the employee is fit to wear a respirator. (C) Whenever an employee has exhibited difficulty in breathing during a respirator fit test or during use of a respirator, the employer, as soon as possible, shall provide the employee with a periodic medical examination in accordance with subsection (l)(4)(B) to determine the employee's fitness to wear a respirator. (D) Where the results of the examination required under subsection (l)(6)(A), (B) or (C) are abnormal, medical limitation or prohibition of respirator use shall be considered. If the employee is allowed to wear a respirator, the employee's ability to continue to do so shall be periodically evaluated by a physician. (7) Emergency Examinations: (A) In addition to the medical surveillance required in subsections (l)(2)-(6), the employer shall provide a medical examination as soon as possible to any employee who may have been acutely exposed to cadmium because of an emergency. (B) The examination shall include the requirements of subsection (l)(4)(B), with emphasis on the respiratory system, other organ systems considered appropriate by the examining physician, and symptoms of acute overexposure, as identified in subsections II(B)(1)-(2) and IV of Appendix A. (8) Termination of Employment Examination: (A) At termination of employment, the employer shall provide a medical examination in accordance with subsection (l)(4)(B), including a chest X-ray where necessary, to any employee to whom at any prior time the employer was required to provide medical surveillance under subsections (l)(1)(A) or (l)(7). However, if the last examination satisfied the requirements of subsection (l)(4)(B) of this standard and was less than six months prior to the date of termination, no further examination is required unless otherwise specified in subsections (l)(3) or (l)(5); (B) In addition, if the employer has discontinued all periodic medical surveillance under (l)(4)(E), no termination of employment medical examination is required. (9) Information Provided to the Physician: The employer shall provide the following information to the examining physician: (A) A copy of this standard and appendices; (B) A description of the affected employee's former, current, and anticipated duties as they relate to the employee's occupational exposure to cadmium; (C) The employee's former, current, and anticipated future levels of occupational exposure to cadmium; (D) A description of any personal protective equipment, including respirators, used or to be used by the employee, including when and for how long the employee has used that equipment; and (E) Relevant results of previous biological monitoring and medical examinations. (10) Physician's Written Medical Opinion: (A) The employer shall promptly obtain a written, signed medical opinion from the examining physician for each medical examination performed on each employee. This written opinion shall contain: 1. The physician's diagnosis for the employee; 2. The physician's opinion as to whether the employee has any detected medical condition(s) that would place the employee at increased risk of material impairment to health from further exposure to cadmium, including any indications of potential cadmium toxicity; 3. The results of any biological or other testing or related evaluations that directly assess the employee's absorption of cadmium; 4. Any recommended removal from, or limitation on the activities or duties of the employee or on the employee's use of personal protective equipment, such as respirators; 5. A statement that the physician has clearly and carefully explained to the employee the results of the medical examination, including all biological monitoring results and any medical conditions related to cadmium exposure that require further evaluation or treatment, and any limitation on the employee's diet or use of medications. (B) The employer shall promptly obtain a copy of the results of any biological monitoring provided by an employer to an employee independently of a medical examination under subsections (l)(2) and (l)(4), and, in lieu of a written medical opinion, an explanation sheet explaining those results. (C) The employer shall instruct the physician not to reveal orally or in the written medical opinion given to the employer specific findings or diagnoses unrelated to occupational exposure to cadmium. (11) Medical Removal Protection (MRP): (A) General. 1. The employer shall temporarily remove an employee from work where there is excess exposure to cadmium on each occasion that medical removal is required under subsections (l)(3), (l)(4), or (l)(6) and on each occasion that a physician determines in a written medical opinion that the employee should be removed from such exposure. The physician's determination may be based on biological monitoring results, inability to wear a respirator, evidence of illness, other signs or symptoms of cadmium-related dysfunction or disease, or any other reason deemed medically sufficient by the physician. 2. The employer shall medically remove an employee in accordance with subsection (l)(11) regardless of whether at the time of removal a job is available into which the removed employee may be transferred. 3. Whenever an employee is medically removed under subsection (l)(11), the employer shall transfer the removed employee to a job where the exposure to cadmium is within the permissible levels specified in that subsection as soon as one becomes available. 4. For any employee who is medically removed under the provisions of subsection (l)(11)(A), the employer shall provide follow-up medical examinations semi-annually until, in a written medical opinion, the examining physician determines that either the employee may be returned to his/her former job status or the employee must be permanently removed from excess cadmium exposure. 5. The employer may not return an employee who has been medically removed for any reason to his/her former job status until a physician determines in a written medical opinion that continued medical removal is no longer necessary to protect the employee's health. (B) Where an employee is found unfit to wear a respirator under subsection (l)(6)(B), the employer shall remove the employee from work where exposure to cadmium is above the PEL. (C) Where removal is based upon any reason other than the employee's inability to wear a respirator, the employer shall remove the employee from work where exposure to cadmium is at or above the action level. (D) Except as specified in subsection (l)(11)(E), no employee who was removed because his/her level of CdU, CdB and/or<>2-M exceeded the trigger levels in subsections (l)(3) or (l)(4) may be returned to work with exposure to cadmium at or above the action level until the employee's levels of CdU fall to or below 3<>g/g Cr, CdB fall to or below 5mg/lwb, and<>2-M fall to or below 300<>g/g Cr. (E) However, when in the examining physician's opinion continued exposure to cadmium will not pose an increased risk to the employee's health and there are special circumstances that make continued medical removal an inappropriate remedy, the physician shall fully discuss these matters with the employee, and then in a written determination may return a worker to his/her former job status despite what would otherwise be unacceptably high biological monitoring results. Thereafter and until such time as the employee's biological monitoring results have decreased to levels where he/she could have been returned to his/her former job status, the returned employee shall continue medical surveillance as if he/she were still on medical removal. Until such time, the employee is no longer subject to mandatory medical removal. Subsequent questions regarding the employee's medical removal shall be decided solely by a final medical determination. (F) Where an employer, although not required by this section to do so, removes an employee from exposure to cadmium or otherwise places limitations on an employee due to the effects of cadmium exposure on the employee's medical condition, the employer shall provide the same medical removal protection benefits to that employee under subsection (l)(12) as would have been provided had the removal been required under subsection (l)(11). (12) Medical Removal Protection Benefits. (A) The employer shall provide medical removal protection benefits to an employee for up to a maximum of 18 months each time, and while the employee is temporarily medically removed under subsection (l)(11). (B) For purposes of this section, the requirement that the employer provide medical removal protection benefits means that the employer shall maintain the total normal earnings, seniority, and all other employee rights and benefits of the removed employee, including the employee's right to his/her former job status, as if the employee had not been removed from the employee's job or otherwise medically limited. (C) Where, after 18 months on medical removal because of elevated biological monitoring results, the employee's monitoring results have not declined to a low enough level to permit the employee to be returned to his/her former job status: 1. the employer shall make available to the employee a medical examination pursuant to this section in order to obtain a final medical determination as to whether the employee may be returned to his/her former job status or must be permanently removed from excess cadmium exposure; and 2. the employer shall assure that the final medical determination indicates whether the employee may be returned to his/her former job status and what steps, if any, should be taken to protect the employee's health; (D) The employer may condition the provision of medical removal protection benefits upon the employee's participation in medical surveillance provided in accordance with this section. (13) Multiple Physician Review. (A) If the employer selects the initial physician to conduct any medical examination or consultation provided to an employee under this section, the employee may designate a second physician to: 1.

This section applies to all construction work where an employee may be occupationally exposed to lead. All construction work excluded from coverage in the general industry standard for lead by section 5198(a)(2) is covered by this standard. Construction work is defined as work for construction, alteration and/or repair, including painting and decorating. It includes but is not limited to the following: (1) Demolition or salvage of structures where lead or materials containing lead are present; (2) Removal or encapsulation of materials containing lead; (3) New construction, alteration, repair, or renovation of structures, substrates, or portions thereof, that contain lead, or materials containing lead; (4) Installation of products containing lead; (5) Lead contamination/emergency cleanup; (6) Transportation, disposal, storage, or containment of lead or materials containing lead on the site or location at which construction activities are performed, and (7) Maintenance operations associated with the construction activities described in this subsection. (b) Definitions. Action level means employee exposure, without regard to the use of respirators, to an airborne concentration of lead of 30 micrograms per cubic meter of air (30mg/m 3) calculated as an 8-hour time-weighted average (TWA). Chief means the Chief of the Division of Occupational Safety and Health or designee. Lead means metallic lead, all inorganic lead compounds, and organic lead soaps. Excluded from this definition are all other organic lead compounds. NIOSH means the National Institute of Occupational Safety and Health (NIOSH), U.S. Department of Health and Human Services or designee. Supervisor means one who is capable of identifying existing and predictable lead hazards in the surroundings or working conditions and who has authorization to take prompt corrective measures to eliminate them. Supervisors shall be trained, as required by this section, and, when required, be certified consistent with section (l)(3). (c) Permissible exposure limit. (1) The employer shall assure that no employee is exposed to lead at concentrations greater than fifty micrograms per cubic meter of air (50mg/m 3) averaged over an 8-hour period. (2) If an employee is exposed to lead for more than 8 hours in any work day the employees' allowable exposure, as a time weighted average (TWA) for that day, shall be reduced according to the following formula: Allowable employee exposure (inmg/m 3)=400 divided by hours worked in the day. (3) When respirators are used to limit employee exposure as required under subsection (c) and all the requirements of subsections (e)(1) and (f) have been met, employee exposure may be considered to be at the level provided by the protection factor of the respirator for those periods the respirator is worn. Those periods may be averaged with exposure levels during periods when respirators are not worn to determine the employee's daily TWA exposure. (d) Exposure assessment. (1) General. (A) Each employer who has a workplace or operation covered by this standard shall initially determine if any employee may be exposed to lead at or above the action level. (B) For the purposes of subsection (d), employee exposure is that exposure which would occur if the employee were not using a respirator. (C) With the exception of monitoring under subsection (d)(3), where monitoring is required under this section, the employer shall collect personal samples representative of a full shift including at least one sample for each job classification in each work area either for each shift or for the shift with the highest exposure level. (D) Full shift personal samples shall be representative of the monitored employee's regular, daily exposure to lead. (2) Protection of employees during assessment of exposure. (A) With respect to the lead related tasks listed in subsection (d)(2)(A), where lead is present, until the employer performs an employee exposure assessment as required in subsection (d) and documents that the employee performing any of the listed tasks is not exposed above the PEL, the employer shall treat the employee as if the employee were exposed above the PEL, and not in excess of ten (10) times the PEL, and shall implement employee protective measures prescribed in subsection (d)(2)(E). The tasks covered by this requirement are: 1. Where lead containing coatings or paint are present: manual demolition of structures (e.g., dry wall), manual scraping, manual sanding, heat gun applications, and power tool cleaning with dust collection systems; 2. Spray painting with lead paint (B) In addition, with regard to tasks not listed in subsection (d)(2)(A), where the employer has any reasons to believe that an employee performing the task may be exposed to lead in excess of the PEL, until the employer performs an employee exposure assessment as required by subsection (d) and documents that the employee's lead exposure is not above the PEL the employer shall treat the employee as if the employee were exposed above the PEL and shall implement employee protective measures as prescribed in subsection (d)(2)(E). (C) With respect to the tasks listed in this subsection (d)(2)(C), where lead is present, until the employer performs an employee exposure assessment as required in subsection (d), and documents that the employee performing any of the listed tasks is not exposed in excess of 500mg/m 3, the employer shall treat the employee as if the employee were exposed to lead in excess of 500mg/m 3 and shall implement employee protective measures as prescribed in subsection (d)(2)(E). Where the employer does establish that the employee is exposed to levels of lead below 500mg/m 3, the employer may provide the exposed employee with the appropriate respirator prescribed for such use at such lower exposures, in accordance with Table 1 of this section. The tasks covered by this requirement are: 1. Using lead containing mortar; lead burning 2. Where lead containing coatings or paint are present: rivet busting; power tool cleaning without dust collection systems; cleanup activities where dry expendable abrasives are used; and abrasive blasting enclosure movement and removal. (D) With respect to the tasks listed in this subsection (d)(2)(D) of this section, where lead is present, until the employer performs an employee exposure assessment as required in subsection (d) and documents that the employee performing any of the listed tasks is not exposed to lead in excess of 2,500mg/m 3 (50 x PEL), the employer shall treat the employee as if the employee were exposed to lead in excess of 2,500 mg/m 3 and shall implement employee protective measures as prescribed in subsection (d)(2)(E). Where the employer does establish that the employee is exposed to levels of lead below 2,500mg/m 3, the employer may provide the exposed employee with the appropriate respirator prescribed for use at such lower exposures, in accordance with Table I of this section. Interim protection as described in this subsection is required where lead containing coatings or paint are present on structures when performing: 1. Abrasive blasting, 2. Welding, 3. Cutting, and 4. Torch burning. (E) Until the employer performs an employee exposure assessment as required under subsection (d) and determines actual employee exposure, the employer shall provide to employees performing the tasks described in subsections (d)(2)(A), (d)(2)(B), (d)(2)(C) and (d)(2)(D) with interim protection as follows: 1. Appropriate respiratory protection in accordance with subsection (f). 2. Appropriate personal protective clothing and equipment in accordance with subsection (g). 3. Change areas in accordance with subsection (i)(2). 4. Hand washing facilities in accordance with subsection (i)(5). 5. Biological monitoring in accordance with subsection (j)(1)(A), to consist of blood sampling and analysis for lead and zinc protoporphyrin levels, and 6. Training as required under subsection (l)(1)(A) regarding section 5194, Hazard Communication; training as required under subsection (l)(2)(C), regarding use of respirators; and training in accordance with section 1510, Safety Instruction for Employees. (3) Basis of initial determination. (A) Except as provided under subsections (d)(3)(C) and (d)(3)(D) the employer shall monitor employee exposures and shall base initial determinations on the employee exposure monitoring results and any of the following, relevant considerations: 1. Any information, observations, or calculations which would indicate employee exposure to lead; 2. Any previous measurements of airborne lead; and 3. Any employee complaints of symptoms which may be attributable to exposure to lead. (B) Monitoring for the initial determination where performed may be limited to a representative sample of the exposed employees who the employer reasonably believes are exposed to the greatest airborne concentrations of lead in the workplace. (C) Where the employer has previously monitored for lead exposures, and the data were obtained within the past 12 months during work operations conducted under workplace conditions closely resembling the processes, type of material, control methods, work practices, and environmental conditions used and prevailing in the employer's current operations, the employer may rely on such earlier monitoring results to satisfy the requirements of subsections (d)(3)(A) and (d)(6) if the sampling and analytical methods meet the accuracy and confidence levels of subsection (d)(9). (D) Where the employer has objective data, demonstrating that a particular product or material containing lead or a specific process, operation or activity involving lead cannot result in employee exposure to lead at or above the action level during processing, use, or handling, the employer may rely upon such data instead of implementing initial monitoring. 1. The employer shall establish and maintain an accurate record documenting the nature and relevance of objective data as specified in subsection (n)(4), where used in assessing employee exposure in lieu of exposure monitoring. 2. Objective data, as described in subsection (d)(3)(D), is not permitted to be used for exposure assessment in connection with subsection (d)(2). 3. Objective data for surface coatings and materials that contain lead shall meet the following methodology: a. Lead analysis shall be performed for each unique surface coating and material that may constitute a health hazard to employees engaged in activities within the scope of this section and; b. Analysis of surface coatings and materials shall be performed in a manner that meets the requirements of subsection (d)(9) and shall be recorded, as described in subsection (n)(4), (4) Positive initial determination and initial monitoring. (A) Where a determination conducted under subsections (d)(1), (2) and (3) shows the possibility of any employee exposure at or above the action level the employer shall conduct monitoring which is representative of the exposure for each employee in the workplace who is exposed to lead. (B) Where the employer has previously monitored for lead exposure, and the data were obtained within the past 12 months during work operations conducted under workplace conditions closely resembling the processes, type of material, control methods, work practices, and environmental conditions used and prevailing in the employer's current operations, the employer may rely on such earlier monitoring results to satisfy the requirements of subsection (d)(4)(A) if the sampling and analytical methods meet the accuracy and confidence levels of subsection (d)(9). (C) Objective data for an initial assessment that demonstrate surface coating or material that contain lead at concentrations equal to or exceeding 0.06% lead dry weight (600 ppm) demonstrate the presence of lead surface coatings or material that constitute a health hazard to employees engaged in lead-related construction work. The lead concentration of paint or materials is based on the lead content in the nonvolatile components of the surface coating or material such as paint. Objective data as described in this subsection are not permitted to be used in lieu of exposure assessment in connection with lead-related tasks listed in subsection (d)(2). (5) Negative initial determination. (A) Where a determination, conducted under subsections (d)(1), (2), and (3) is made that no employee is exposed to airborne concentrations of lead at or above the action level the employer shall make a written record of such determination. The record shall include at least the information specified in subsection (d)(3)(A) and shall also include the date of determination, location within the worksite, and the name and social security number of each employee monitored. (B) Objective data that meet the requirements of subsection (n)(4) for an initial assessment that demonstrate surface coating or material that contain lead at concentrations less than 0.06% lead dry weight (600 ppm) are sufficient to establish a negative determination. The lead concentration of surface coatings or materials is based on the lead content in the nonvolatile components of the surface coating or material such as paint. Objective data as described in this subsection are not permitted to be used in lieu of exposure assessment in connection with lead-related tasks listed in subsection (d)(2). (6) Frequency. (A) If the initial determination reveals employee exposure to be below the action level further exposure determination need not be repeated except as otherwise provided in subsection (d)(7). (B) If the initial determination or subsequent determination reveals employee exposure to be at or above the action level but at or below the PEL the employer shall perform monitoring in accordance with this subsection at least every 6 months. The employer shall continue monitoring at the required frequency until at least two consecutive measurements, taken at least 7 days apart, are below the action level at which time the employer may discontinue monitoring for that employee except as otherwise provided in subsection (d)(7). (C) If the initial determination reveals that employee exposure is above the PEL the employer shall perform monitoring quarterly. The employer shall continue monitoring at the required frequency until at least two consecutive measurements, taken at least 7 days apart, are at or below the PEL but at or above the action level at which time the employer shall repeat monitoring for that employee at the frequency specified in subsection (d)(6)(B), except as otherwise provided in subsection (d)(7). The employer shall continue monitoring at the required frequency until at least two consecutive measurements, taken at least 7 days apart, are below the action level at which time the employer may discontinue monitoring for that employee except as otherwise provided in subsection (d)(7). (7) Additional exposure assessments. Whenever there has been a change of equipment, process, control, personnel or a new task has been initiated that may result in additional employees being exposed to lead at or above the action level or may result in employees already exposed at or above the action level being exposed above the PEL, the employer shall conduct additional monitoring in accordance with this subsection. (8) Employee notification. (A) Within 5 working days after completion of the exposure assessment the employer shall notify each employee in writing of the results which represent that employee's exposure. (B) Whenever the results indicate that the representative employee exposure, without regard to respirators, is at or above the PEL the employer shall include in the written notice a statement that the employees exposure was at or above that level and a description of the corrective action taken or to be taken to reduce exposure to below that level. (9) "Accuracy of measurement". The employer shall use a method of monitoring and analysis which has an accuracy (to a confidence level of 95%) of not less than plus or minus 25 percent for airborne concentrations of lead equal to or greater than 30mg/m 3. Methods for the determination of lead concentrations of surface coatings and material shall be determined by methods which have an accuracy (to a confidence level of 95 percent) of not less than plus or minus 25 percent at 0.06% lead dry weight (600 ppm). (e) Methods of compliance (1) Engineering and work practice controls. (A) General. The employer shall implement engineering and work practice controls, including administrative controls, to reduce and maintain employee exposure to lead to or below the permissible exposure limit to the extent that such controls are feasible. Wherever all feasible engineering and work practices controls that can be instituted are not sufficient to reduce employee exposure to or below the permissible exposure limit prescribed in subsection (c), the employer shall nonetheless use them to reduce employee exposure to the lowest feasible level and shall supplement them by the use of respiratory protection that complies with the requirements of subsection (f). (2) Compliance program. (A) Prior to commencement of the job each employer shall establish and implement a written compliance program to achieve compliance with subsection (c). (B) Written plans for these compliance programs shall include at least the following: 1. A description of each activity in which lead is emitted; e.g. equipment used, material involved, controls in place, crew size, employee job responsibilities, operating procedures and maintenance practices; 2.

The employer shall remove an employee from work having an exposure to lead at or above the action level on each occasion that a final medical determination results in a medical finding, determination, or opinion that the employee has a detected medical condition which places the employee at increased risk of material impairment to health from exposure to lead. 2. For the purposes of this section, the phrase "final medical determination" means the written medical opinion on the employees' health status by the examining physician or, where relevant, the outcome of the multiple physician review mechanism or alternate medical determination mechanism used pursuant to the medical surveillance provisions of this section. 3. Where a final medical determination results in any recommended special protective measures for an employee, or limitations on an employee's exposure to lead, the employer shall implement and act consistent with the recommendation. (C) Return of the employee to former job status. 1. The employer shall return an employee to his or her former job status: a. For an employee removed due to a blood lead level at or above 50mg/dl when two consecutive blood sampling tests indicate that the employee's blood lead level is at or below 40mg/dl; b. For an employee removed due to a final medical determination, when a subsequent final medical determination results in a medical finding, determination, or opinion that the employee no longer has a detected medical condition which places the employee at increased risk of material impairment to health from exposure to lead. 2. For the purposes of this section, the requirement that an employer return an employee to his or her former job status is not intended to expand upon or restrict any rights an employee has or would have had, absent temporary medical removal, to a specific job classification or position under the terms of a collective bargaining agreement. (D) Removal of other employee special protective measure or limitations. The employer shall remove any limitations placed on an employee or end any special protective measures provided to an employee pursuant to a final medical determination when a subsequent final medical determination indicates that the limitations or special protective measures are no longer necessary. (E) Employer options pending a final medical determination. Where the multiple physician review mechanism, or alternate medical determination mechanism used pursuant to the medical surveillance provisions of this section, has not yet resulted in a final medical determination with respect to an employee, the employer shall act as follows: 1. Removal. The employer may remove the employee from exposure to lead, provide special protective measures to the employee, or place limitations upon the employee, consistent with the medical findings, determinations, or recommendations of any of the physicians who have reviewed the employee's health status. 2. Return. The employer may return the employee to his or her former job status, end any special protective measures provided to the employee, and remove any limitations placed upon the employee, consistent with the medical findings, determinations, or recommendations of any of the physicians who have reviewed the employee's health status, with two exceptions. If: a. the initial removal, special protection, or limitation of the employee resulted from a final medical determination which differed from the findings, determinations, or recommendations of the initial physician or; b. If the employee has been on removal status for the preceding eighteen months due to an elevated blood lead level, then the employer shall await a final medical determination. (2) Medical removal protection benefits. (A) Provision of medical removal protection benefits. The employer shall provide an employee up to eighteen (18) months of medical removal protection benefits on each occasion that an employee is removed from exposure to lead or otherwise limited pursuant to this section. (B) Definition of medical removal protection benefits. For the purposes of this section, the requirement that an employer provide medical removal protection benefits means that, as long as the job the employee was removed from continues, the employer shall maintain the total normal earnings, seniority and other employment rights and benefits of an employee, including the employee's right to his or her former job status as though the employee had not been medically removed from the employee's job or otherwise medically limited. (C) Follow-up medical surveillance during the period of employee removal or limitation. During the period of time that an employee is medically removed from his or her job or otherwise medically limited, the employer may condition the provision of medical removal protection benefits upon the employee's participation in follow-up medical surveillance made available pursuant to this section. (D) Workers' compensation claims. If a removed employee files a claim for workers' compensation payments for a lead-related disability, then the employer shall continue to provide medical removal protection benefits pending disposition of the claim. To the extent that an award is made to the employee for earnings lost during the period of removal, the employer's medical removal protection obligation shall be reduced by such amount. The employer shall receive no credit for workers' compensation payments received by the employee for treatment-related expenses. (E) Other credits. The employer's obligation to provide medical removal protection benefits to a removed employee shall be reduced to the extent that the employee receives compensation for earnings lost during the period of removal either from a publicly or employer-funded compensation program, or receives income from employment with another employer made possible by virtue of the employee's removal. (F) Voluntary removal or restriction of an employee. Where an employer, although not required by this section to do so, removes an employee from exposure to lead or otherwise places limitations on an employee due to the effects of lead exposure on the employee's medical condition, the employer shall provide medical removal protection benefits to the employee equal to that required by subsection (k)(2)(A) and (B).

The only subsection (d)(2) task to be performed consists of torch cutting or welding, not to exceed a duration of 1 hour in any shift. Exception No. 2: The employer is not required to notify the Division if the percentage of lead in the material disturbed is less than 0.5%, 5,000 parts per million (weight by weight), or 1.0 mg/cm 2. (1) The employer shall ensure that the information required by subsection (p)(2) is received by the nearest Division District Office at least 24 hours prior to the commencement of the work by any of the following means: (A) Letter; (B) Facsimile; (C) Electronic mail; or (D) Telephone call, followed by written notification sent or mailed within 24 hours of placing the call. Exception: When an employer intends to initiate unforeseen lead-work on an urgent basis within 24 hours, the notification requirement may be met by giving telephone notice to the Division at any time prior to commencement of the work, followed by written notification sent or mailed within 24 hours of telephoning the Division. (2) The written notification provided by the employer shall contain the following: (A) The name, address and phone number of the employer; (B) The address of the job (or common name of the site with closest streets or roadways identified); (C) The precise physical location of the lead related work at the job site; (D) The projected starting date; (E) The expected completion date or approximate duration of the work in days; (F) The approximate number of workers planned to do the lead-related work; (G) The type of structure(s) in which or on which the work is to be performed; (H) The amount of lead containing material to be disturbed in square feet or linear feet; (I) A description of the type of lead-related work to be performed and work practices that will be utilized; (J) The name of the supervisor who will be responsible for the lead-related work; and (K) The amount of lead in the disturbed materials (percent by weight, parts per million or milligrams per square centimeter) if known. (3) The employer shall notify the Division, and provide the current information, if changes are made to the starting date, the surface area to be disturbed, or the type of lead-related work performed or work practices to be utilized, before or upon adoption of that change. (4) An employer conducting ongoing, lead-related operations and maintenance work on stationary steel structures need only notify the Division once for each structure if the duration of the operations and maintenance work is less than one year. If the duration of the work is more than one year, the employer shall submit to the Division at least once per year a supplemental written notification updating all of the information required by subsection (p)(2) for each structure. (q) Appendices. The information contained in the appendices to this section is not intended by itself, to create any additional obligations not otherwise imposed by this standard nor detract from any existing obligation. Appendix A to s 1532.1 - Substance Data Sheet for Occupational Exposure to Lead I. Substance Identification A. Substance: Pure lead (Pb) is a heavy metal at room temperature and pressure and is a basic chemical element. It can combine with various other substances to form numerous lead compounds. B. Compounds covered by the standard: The word "lead" when used in this standard means elemental lead, all inorganic lead compounds and a class of organic lead compounds called lead soaps. This standard does not apply to other organic lead compounds. C. Uses: Exposure to lead occurs in several different occupations in the construction industry, including demolition or salvage of structures where lead or lead-containing materials are present; removal or encapsulation of lead-containing materials, new construction, alteration, repair, or renovation of structures that contain lead or materials containing lead; installation of products containing lead. In addition, there are construction related activities where exposure to lead may occur, including transportation, disposal, storage, or containment of lead or materials containing lead on construction sites, and maintenance operations associated with construction activities. D. Permissible exposure: The permissible exposure limit (PEL) set by the standard is 50 micrograms of lead per cubic meter of air (50mg/m 3) averaged over an 8-hour workday. E. Action level: The standard establishes an action level of 30 micrograms of lead per cubic meter of air (30mg/m 3) averaged over an 8-hour workday. The action level triggers several ancillary provisions of the standard such as exposure monitoring, medical surveillance, and training. II. Health Hazard Data A. Ways in which lead enters your body. When absorbed into your body in certain doses, lead is a toxic substance. The object of the lead standard is to prevent absorption of harmful quantities of lead. The standard is intended to protect you not only from the immediate toxic effects of lead, but also from the serious toxic effects that may not become apparent until years of exposure have passed. Lead can be absorbed into your body by inhalation (breathing) and ingestion (eating). Lead (except for certain organic lead compounds not covered by the standard, such as tetraethyl lead) is not absorbed through your skin. When lead is scattered in the air as a dust, fume or mist it can be inhaled and absorbed through your lungs and upper respiratory tract. Inhalation of airborne lead is generally the most important source of occupational lead absorption. You can also absorb lead through your digestive system if lead gets into your mouth and is swallowed. If you handle food, cigarettes, chewing tobacco, or make-up which have lead on them or handle them with hands contaminated with lead, this will contribute to ingestion. A significant portion of the lead that you inhale or ingest gets into your blood stream. Once in your blood stream, lead is circulated throughout your body and stored in various organs and body tissues. Some of this lead is quickly filtered out of your body and excreted, but some remains in the blood and other tissues. As exposure to lead continues, the amount stored in your body will increase if you are absorbing more lead than your body is excreting. Even though you may not be aware of any immediate symptoms of disease, this lead stored in your tissues can be slowly causing irreversible damage, first to individual cells, then to your organs and whole body systems. B. Effects of overexposure to lead. (1) Short term (acute) overexposure. Lead is a potent, systemic poison that serves no known useful function once absorbed by your body. Taken in large enough doses, lead can kill you in a matter of days. A condition affecting the brain called acute encephalopathy may arise which develops quickly to seizures, coma, and death from cardiorespiratory arrest. A short term dose of lead can lead to acute encephalopathy. Short term occupational exposures of this magnitude are highly unusual, but not impossible. Similar forms of encephalopathy may, however, arise from extended, chronic exposure to lower doses of lead. There is no sharp dividing line between rapidly developing acute effects of lead, and chronic effects which take longer to acquire. Lead adversely affects numerous body systems, and causes forms of health impairment and disease which arise after periods of exposure as short as days or as long as several years. (2) Long-term (chronic) overexposure. Chronic overexposure to lead may result in severe damage to your blood-forming, nervous, urinary and reproductive systems. Some common symptoms of chronic overexposure include loss of appetite, metallic taste in the mouth, anxiety, constipation, nausea, pallor, excessive tiredness, weakness, insomnia, headache, nervous irritability, muscle and joint pain or soreness, fine tremors, numbness, dizziness, hyperactivity and colic. In lead colic there may be severe abdominal pain. Damage to the central nervous system in general and the brain (encephalopathy) in particular is one of the most severe forms of lead poisoning. The most severe, often fatal, form of encephalopathy may be preceded by vomiting, a feeling of dullness progressing to drowsiness and stupor, poor memory, restlessness, irritability, tremor, and convulsions. It may arise suddenly with the onset of seizures, followed by coma, and death. There is a tendency for muscular weakness to develop at the same time. This weakness may progress to paralysis often observed as a characteristic "wrist drop" or "foot drop" and is a manifestation of a disease to the nervous system called peripheral neuropathy. Chronic overexposure to lead also results in kidney disease with few, if any, symptoms appearing until extensive and most likely permanent kidney damage has occurred. Routine laboratory tests reveal the presence of this kidney disease only after about two-thirds of kidney function is lost. When overt symptoms of urinary dysfunction arise, it is often too late to correct or prevent worsening conditions, and progression to kidney dialysis or death is possible. Chronic overexposure to lead impairs the reproductive systems of both men and women. Overexposure to lead may result in decreased sex drive, impotence and sterility in men. Lead can alter the structure of sperm cells raising the risk of birth defects. There is evidence of miscarriage and stillbirth in women whose husbands were exposed to lead or who were exposed to lead themselves. Lead exposure also may result in decreased fertility, and abnormal menstrual cycles in women. The course of pregnancy may be adversely affected by exposure to lead since lead crosses the placental barrier and poses risks to developing fetuses. Children born of parents either one of whom were exposed to excess lead levels are more likely to have birth defects, mental retardation, behavioral disorders or die during the first year of childhood. Overexposure to lead also disrupts the blood-forming system resulting in decreased hemoglobin (the substance in the blood that carries oxygen to the cells) and ultimately anemia. Anemia is characterized by weakness, pallor and fatigability as a result of decreased oxygen carrying capacity in the blood. (3) Health protection goals of the standard. Prevention of adverse health effects for most workers from exposure to lead throughout a working lifetime requires that a worker's blood lead level (BLL, also expressed as PbB) be maintained at or below forty micrograms per deciliter of whole blood (40mg/dl). The blood lead levels of workers (both male and female workers) who intend to have children should be maintained below 30mg/dl to minimize adverse reproductive health effects to the parents and to the developing fetus. The measurement of your blood lead level (BLL) is the most useful indicator of the amount of lead being absorbed by your body. Blood lead levels are most often reported in units of milligrams (mg) or micrograms (ug) of lead (1 mg=1000mg) per 100 grams (100g), 100 milliliters (100 ml) or deciliter (dl) of blood. These three units are essentially the same. Sometime BLLs are expressed in the form of mg% ormg%. This is a shorthand notation for 100g, 100 ml, or dl. (Reference to BLL measurements in this standard are expressed in the form ofmg/dl.) BLL measurements show the amount of lead circulating in your blood stream, but do not give any information about the amount of lead stored in your various tissues. BLL measurements merely show current absorption of lead, not the effect that lead is having on your body or the effects that past lead exposure may have already caused. Past research into lead-related diseases, however, has focused heavily on associations between BLLs and various diseases. As a result, your BLL is an important indicator of the likelihood that you will gradually acquire a lead-related health impairment or disease. Once your blood lead level climbs about 40mg/dl, your risk of disease increases. There is a wide variability of individual response to lead, thus it is difficult to say that a particular BLL in a given person will cause a particular effect. Studies have associated fatal encephalopathy with BLLs as low as 150mg/dl. Other studies have shown other forms of diseases in some workers with BLLs well below 80mg/dl. Your BLL is a crucial indicator of the risks to your health, but one other factor is also extremely important. This factor is the length of time you have had elevated BLLs. The longer you have an elevated BLL, the greater the risk that large quantities of lead are being gradually stored in your organs and tissues (body burden). The greater your overall body burden, the greater the chances of substantial permanent damage. The best way to prevent all forms of lead-related impairments and diseases -- both short term and long term -- is to maintain your BLL below 40mg/dl. The provisions of the standard are designed with this end in mind. Your employer has prime responsibility to assure that the provisions of the standard are complied with both by the company and by individual workers. You, as a worker, however, also have a responsibility to assist your employer in complying with the standard. You can play a key role in protecting your own health by learning about the lead hazards and their control, learning what the standard requires, following the standard where it governs your own actions, and seeing that your employer complies with provisions governing his or her actions. (4) Reporting signs and symptoms of health problems. You should immediately notify your employer if you develop signs or symptoms associated with lead poisoning or if you desire medical advice concerning the effects of current or past exposure to lead or your ability to have a healthy child. You should also notify your employer if you have difficulty breathing during a respirator fit test or while wearing a respirator. In each of these cases, your employer must make available to you appropriate medical examinations or consultations. These must be provided at no cost to you and at a reasonable time and place. The standard contains a procedure whereby you can obtain a second opinion by a physician of your choice if your employer selected the initial physician. Appendix B to s 1532.1 -Employee Standard Summary This appendix summarizes key provisions of the standard for lead in construction that you as a worker should become familiar with. I. Permissible Exposure Limit (PEL) - subsection (c) The standard sets a permissible exposure limit (PEL) of 50 micrograms of lead per cubic meter of air (50mg/m 3), averaged over an 8-hour workday which is referred to as a time-weighted average (TWA). This is the highest level of lead in air to which you may be permissibly exposed over an 8-hour workday. However, since this is an 8-hour average, short exposures above the PEL are permitted so long as for each 8-hour work day your average exposure does not exceed this level. This standard, however, takes into account the fact that your daily exposure to lead can extend beyond a typical 8-hour workday as the result of overtime or other alterations in your work schedule. To deal with this situation, the standard contains a formula which reduces your permissible exposure when you are exposed more than 8 hours. For example, if you are exposed to lead for 10 hours a day, the maximum permitted average exposure would be 40mg/m 3. II. Exposure Assessment - Subsection (d) If lead is present in your workplace in any quantity, your employer is required to make an initial determination of whether any employee's exposure to lead exceeds the action level (30mg/m 3 averaged over an 8-hour day). Employee exposure is that exposure which would occur if the employee were not using a respirator. This initial determination requires your employer to monitor workers' exposures unless he or she has objective data which can demonstrate conclusively that no employee will be exposed to lead in excess of the action level. Where objective data is used in lieu of actual monitoring the employer must establish and maintain an accurate record, documenting its relevancy in assessing exposure levels for current job conditions. If such objective data is available, the employer need proceed no further on employee exposure assessment until such time that conditions have changed and the determination is no longer valid. Objective data for surfaces and materials that is less than 0.06% lead dry weight (600 ppm) is indicative of materials that will not give lead concentrations above the action level. Lead analysis must be performed for each unique surface coating or material. Surface coating or material objective data cannot be used to replace air monitoring for exposure assessments required for the lead-related tasks listed in subsection (d)(2). Objective data may be compiled from various sources, e.g., insurance companies and trade associations and information from suppliers or exposure data collected from similar operations. Objective data may also comprise previously-collected sampling data including area monitoring. If it cannot be determined through using objective data that worker exposure is less than the action level, your employer must conduct monitoring or must rely on relevant previous personal sampling, if available. Where monitoring is required for the initial determination, it may be limited to a representative number of employees who are reasonably expected to have the highest exposure levels. If your employer has conducted appropriate air sampling for lead in the past 12 months, he or she may use these results, provided they are applicable to the same employee tasks and exposure conditions and meet the requirements for accuracy as specified in the standard. As with objective data, if such results are relied upon for the initial determination, your employer must establish and maintain a record as to the relevancy of such data to current job conditions. If there have been any employee complaints of symptoms which may be attributable to exposure to lead or if there is any other information or observations which would indicate employee exposure to lead, this must also be considered as part of the initial determination. If this initial determination shows that a reasonable possibility exists that any employee may be exposed, without regard to respirators, over the action level, your employer must set up an air monitoring program to determine the exposure level representative of each employee exposed to lead at your workplace. In carrying out this air monitoring program, your employer is not required to monitor the exposure of every employee, but he or she must monitor a representative number of employees and job types. Enough sampling must be done to enable each employee's exposure level to be reasonably represent full shift exposure. In addition, these air samples must be taken under conditions which represent each employee's regular, daily exposure to lead. Sampling performed in the past 12 months may be used to determine exposures above the action level if such sampling was conducted during work activities essentially similar to present work conditions. The standard lists certain tasks which may likely result in exposures to lead in excess of the PEL and, in some cases, exposures in excess of 50 times the PEL. If you are performing any of these tasks, your employer must provide you with appropriate respiratory protection, protective clothing and equipment, change areas, hand washing facilities, biological monitoring, and training until such time that an exposure assessment is conducted which demonstrates that your exposure level is below the PEL. Objective data cannot be used to replace air monitoring for this exposure assessment. If you are exposed to lead and air sampling is performed, your employer is required to notify you in writing within 5 working days of the air monitoring results which represent your exposure. If the results indicate that your exposure exceeds the PEL (without regard to your use of a respirator), then your employer must also notify you of this in writing, and provide you with a description of the corrective action that has been taken or will be taken to reduce your exposure. Your exposure must be rechecked by monitoring, at least every six months if your exposure is at or over the action level but below the PEL. Your employer may discontinue monitoring for you if 2 consecutive measurements, taken at least 7 days apart, are at or below the action level. Air monitoring must be repeated every 3 months if you are exposed over the PEL. Your employer must continue monitoring for you at this frequency until 2 consecutive measurements, taken at least 7 days apart, are below the PEL but above the action level, at which time your employer must repeat monitoring of your exposure every six months and may discontinue monitoring only after your exposure drops to or below the action level. However, whenever there is a change of equipment, process, control, or personnel or a new type of job is added at your workplace which may result in new or additional exposure to lead, your employer must perform additional monitoring. III. Methods of Compliance - Subsection (e) Your employer is required to assure that no employee is exposed to lead in excess of the PEL as an 8-hour TWA. The standard for lead in construction requires employers to institute engineering and work practice controls including administrative controls to the extent feasible to reduce employee exposure to lead. Where such controls are feasible but not adequate to reduce exposures below the PEL they must be used nonetheless to reduce exposures to the lowest level that can be accomplished by these means and then supplemented with appropriate respiratory protection. Your employer must establish a regulated area that includes the work area where airborne exposure to lead is above the PEL, or where the lead-related tasks listed in subsection (d)(2) are performed. Your employer is required to develop and implement a written compliance program prior to the commencement of any job where employee exposures may reach the PEL as an 8-hour TWA. The standard identifies the various elements that must be included in the plan. For example, employers are required to include a description of operations in which lead is emitted, detailing other relevant information about the operation such as the type of equipment used, the type of material involved, employee job responsibilities, operating procedures and maintenance practices. In addition, your employer's compliance plan must specify the means that will be used to achieve compliance and, where engineering controls are required, include any engineering plans or studies that have been used to select the control methods. If administrative controls involving job rotation are used to reduce employee exposure to lead, the job rotation schedule must be included in the compliance plan. The plan must also detail the type of protective clothing and equipment, including respirators, housekeeping and hygiene practices that will be used to protect you from the adverse effects of exposure to lead. The written compliance program must be made available, upon request, to affected employees and their designated representatives, the Chief and NIOSH. Finally, the plan must be reviewed and updated at least every 6 months to assure it reflects the current status in exposure control. IV. Respiratory Protection - Subsection (f) Your employer is required to provide and assure your use of respirators when your exposure to lead is not controlled below the PEL by other means. The employer must pay the cost of the respirator. Whenever you request one, your employer is also required to provide you a respirator even if your air exposure level is not above the PEL. You might desire a respirator when, for example, you have received medical advice that your lead absorption should be decreased. Or, you may intend to have children in the near future, and want to reduce the level of lead in your body to minimize adverse reproductive effects. While respirators are the least satisfactory means of controlling your exposure, they are capable of providing significant protection if properly chosen, fitted, worn, cleaned, maintained, and replaced when they stop providing adequate protection. Your employer is required to select respirators from the types listed in Table I of the Respiratory Protection section of the standard (section 1532.1(f)). Any respirator chosen must be approved by the National Institute for Occupational Safety and Health (NIOSH) under the provisions of 42 CFR part 84. This respirator selection table will enable your employer to choose a type of respirator which will give you a proper amount of protection based on your airborne lead exposure. Your employer may select a type of respirator that provides greater protection than that required by the standard; that is, one recommended for a higher concentration of lead than is present in your workplace. For example, a powered air purifying respirator (PAPR) is much more protective than a typical negative pressure respirator, and may also be more comfortable to wear. A PAPR has a filter, cartridge or canister to clean the air, and a power source which continuously blows filtered air into your breathing zone. Your employer might make a PAPR available to you to ease the burden of having to wear a respirator for long periods of time. The standard provides that you can obtain a PAPR upon request. Your employer must assure that your respirator facepiece fits properly. Proper fit of a respirator facepiece is critical. Obtaining a proper fit on each employee may require your employer to make available two or three different mask types. In order to assure that your respirator fits properly and that facepiece leakage is minimized, your employer must give you either a qualitative fit test or a quantitative fit test as specified in Appendix A of the Respiratory Protection standard located at section 5144. You must also receive from your employer proper training in the use of respirators. Your employer is required to teach you how to wear a respirator, to know why it is needed, and to understand its limitations. The standard provides that if your respirator uses filter elements, you must be given an opportunity to change the filter elements whenever an increase in breathing resistance is detected. You also must be permitted to periodically leave your work area to wash your face and respirator facepiece whenever necessary to prevent skin irritation. If you ever have difficulty in breathing during a fit test or while using a respirator, your employer must make a medical examination available to you to determine whether you can safely wear a respirator. The result of this examination may be to give you a positive pressure respirator (which reduces breathing resistance) or to provide alternative means of protection. V. Protective Work Clothing and Equipment - Subsection (g) If you are exposed to lead above the PEL as an 8-hour TWA, without regard to your use of a respirator, or if you are exposed to lead compounds such as lead arsenate or lead azide which can cause skin and eye irritation, your employer must provide you with protective work clothing and equipment appropriate for the hazard. If work clothing is provided, it must be provided in a clean and dry condition at least weekly, and daily if your airborne exposure to lead is greater than 200mg/m 3. Appropriate protective work clothing and equipment can include coveralls or similar full-body work clothing, gloves, hats, shoes or disposable shoe coverlets, and face shields or vented goggles. Your employer is required to provide all such equipment at no cost to you. In addition, your employer is responsible for providing repairs and replacement as necessary, and also is responsible for the cleaning, laundering or disposal of protective clothing and equipment. The standard requires that your employer assure that you follow good work practices when you are working in areas where your exposure to lead may exceed the PEL. With respect to protective clothing and equipment, where appropriate, the following procedures should be observed prior to beginning work: 1. Change into work clothing and shoe covers in the clean section of the designated changing areas; 2. Use work garments of appropriate protective gear, including respirators before entering the work area; and 3. Store any clothing not worn under protective clothing in the designated changing area. Workers should follow these procedures upon leaving the work area: 1. HEPA vacuum heavily contaminated protective work clothing while it is still being worn. At no time may lead be removed from protective clothing by any means which result in uncontrolled dispersal of lead into the air; 2. Remove shoe covers and leave them in the work area; 3. Remove protective clothing and gear in the dirty area of the designated changing area. Remove protective coveralls by carefully rolling down the garment to reduce exposure to dust. 4. Remove respirators last; and 5. Wash hands and face. Workers should follow these procedures upon finishing work for the day (in addition to procedures described above): 1. Where applicable, place disposal coveralls and shoe covers with the abatement waste; 2. Contaminated clothing which is to be cleaned, laundered or disposed of must be placed in closed containers in the change room. 3. Clean protective gear, including respirators, according to standard procedures; 4. Wash hands and face again. If showers are available, take a shower and wash hair. If shower facilities are not available at the work site, shower immediately at home and wash hair. VI. Housekeeping - Subsection (h) Your employer must establish a housekeeping program sufficient to maintain all surfaces as free as practicable of accumulations of lead dust. Vacuuming is the preferred method of meeting this requirement, and the use of compressed air to clean floors and other surfaces is generally prohibited unless removal with compressed air is done in conjunction with ventilation systems designed to contain dispersal of the lead dust. Dry or wet sweeping, shoveling, or brushing may not be used except where vacuuming or other equally effective methods have been tried and do not work. Vacuums must be used equipped with a special filter called a high-efficiency particulate air (HEPA) filter and emptied in a manner which minimizes the reentry of lead into the workplace. VII. Hygiene Facilities, Practices and Regulated Areas - Subsection (i) The standard requires that hand washing facilities be provided where occupational exposure to lead occurs. In addition, change areas, showers (where feasible), and lunchrooms or eating areas are to be made available to workers exposed to lead above the PEL. Your employer must assure that except in these facilities, food and beverage is not present or consumed, tobacco products are not present or used, and cosmetics are not applied, where airborne exposures are above the PEL. Change rooms provided by your employer must be equipped with separate storage facilities for your protective clothing and equipment and street clothes to avoid cross-contamination. After showering, no required protective clothing or equipment worn during the shift may be worn home. It is important that contaminated clothing or equipment be removed in change areas and not be worn home or you will extend your exposure and expose your family since lead from your clothing can accumulate in your house, car, etc. Lunchrooms or eating areas may not be entered with protective clothing or equipment unless surface dust has been removed by vacuuming, downdraft booth, or other cleaning method. Finally, workers exposed above the PEL must wash both their hands and faces prior to eating, drinking, smoking or applying cosmetics. All of the facilities and hygiene practices just discussed are essential to minimize additional sources of lead absorption from inhalation or ingestion of lead that may accumulate on you, your clothes, or your possessions. Therefore, employers shall establish regulated areas, where access is controlled by the supervisor for work areas where employees are exposed to lead at or above the PEL or performing the specific tasks that require air monitoring, as required by subsection (d)(2). Any employee that enters the regulated area must be provided with protective equipment. Strict compliance with these provisions can virtually eliminate several sources of lead exposure which significantly contribute to excessive lead absorption. VIII. Medical Surveillance - Subsection (j) The medical surveillance program is part of the standard's comprehensive approach to the prevention of lead-related disease. Its purpose is to supplement the main thrust of the standard which is aimed at minimizing airborne concentrations of lead and sources of ingestion. Only medical surveillance can determine if the other provisions of the standard have affectively protected you as an individual. Compliance with the standard's provision will protect most workers from the adverse effects of lead exposure, but may not be satisfactory to protect individual workers (1) who have high body burdens of lead acquired over past years, (2) who have additional uncontrolled sources of non-occupational lead exposure, (3) who exhibit unusual variations in lead absorption rates, or (4) who have specific non-work related medical conditions which could be aggravated by lead exposure (e.g., renal disease, anemia). In addition, control systems may fail, or hygiene and respirator programs may be inadequate. Periodic medical surveillance of individual workers will help detect those failures. Medical surveillance will also be important to protect your reproductive ability-regardless of whether you are a man or woman. All medical surveillance required by the standard must be performed by or under the supervision of a licensed physician. The employer must provide required medical surveillance without cost to employees and at a reasonable time and place. The standard's medical surveillance program has two parts -- periodic biological monitoring and medical examinations. Your employer's obligation to offer you medical surveillance is triggered by the results of the air monitoring program. Full medical surveillance must be made available to all employees who are or may be exposed to lead in excess of the action level for more than 30 days a year and whose blood lead level exceeds 40mg/dl. Initial medical surveillance consisting of blood sampling and analysis for lead and zinc protoporphyrin must be provided to all employees exposed at any time (1 day) above the action level. Biological monitoring under the standard must be provided at least every 2 months for the first 6 months and every 6 months thereafter until your blood lead level is below 40mg/dl. A zinc protoporphyrin (ZPP) test is a very useful blood test which measures an adverse metabolic effect of lead on your body and is therefore an indicator of lead toxicity. If your BLL exceeds 40mg/dl the monitoring frequency must be increased from every 6 months to at least every 2 months and not reduced until two consecutive BLLs indicate a blood lead level below 40mg/dl. Each time your BLL is determined to be over 40mg/dl, your employer must notify you of this in writing within five working days of his or her receipt of the test results. The employer must also inform you that the standard requires temporary medical removal with economic protection when your BLL exceeds 50mg/dl. (See Discussion of Medical Removal Protection-Subsection (k).) Anytime your BLL exceeds 50mg/dl your employer must make available to you within two weeks of receipt of these test results a second follow-up BLL test to confirm your BLL. If the two tests both exceed 50mg/dl, and you are temporarily removed, then your employer must make successive BLL tests available to you on a monthly basis during the period of your removal. Medical examinations beyond the initial one must be made available on an annual basis if your blood lead level exceeds 40mg/dl at any time during the preceding year and you are being exposed above the airborne action level of 30mg/m 3 for 30 or more days per year. The initial examination will provide information to establish a baseline to which subsequent data can be compared. An initial medical examination to consist of blood sampling and analysis for lead and zinc protoporphyrin must also be made available (prior to assignment) for each employee being assigned for the first time to an area where the airborne concentration of lead equals or exceeds the action level at any time. In addition, a medical examination or consultation must be made available as soon as possible if you notify your employer that you are experiencing signs or symptoms commonly associated with lead poisoning or that you have difficulty breathing while wearing a respirator or during a respirator fit test. You must also be provided a medical examination or consultation if you notify your employer that you desire medical advice concerning the effects of current or past exposure to lead on your ability to procreate a healthy child. Finally, appropriate follow-up medical examinations or consultations may also be provided for employees who have been temporarily removed from exposure under the medical removal protection provisions of the standard. (See Part IX, below.) The standard specifies the minimum content of pre-assignment and annual medical examinations. The content of other types of medical examinations and consultations is left up to the sound discretion of the examining physician. Pre-assignment and annual medical examinations must include (1) a detailed work history and medical history; (2) a thorough physical examination, including an evaluation of your pulmonary status if you will be required to use a respirator; (3) a blood pressure measurement; and (4) a series of laboratory tests designed to check your blood chemistry and your kidney function. In addition, at any time upon your request, a laboratory evaluation of male fertility will be made (microscopic examination of a sperm sample), or a pregnancy test will be given. The standard does not require that you participate in any of the medical procedures, tests, etc. which your employer is required to make available to you. Medical surveillance can, however, play a very important role in protecting your health. You are strongly encouraged, therefore, to participate in a meaningful fashion. The standard contains a multiple physician review mechanism which will give you a chance to have a physician of your choice directly participate in the medical surveillance program. If you are dissatisfied with an examination by a physician chosen by your employer, you can select a second physician to conduct an independent analysis. The two doctors would attempt to resolve any differences of opinion, and select a third physician to resolve any firm dispute. Generally your employer will choose the physician who conducts medical surveillance under the lead standard - unless you and your employer can agree on the choice of a physician or physicians. Some companies and unions have agreed in advance, for example, to use certain independent medical laboratories or panels of physicians. Any of these arrangements are acceptable so long as required medical surveillance is made available to workers. The standard requires your employer to provide certain information to a physician to aid in his or her examination of you. This information includes (1) the standard and its appendices, (2) a description of your duties as they relate to occupational lead exposure, (3) your exposure level or anticipated exposure level, (4) a description of any personal protective equipment you wear, (5) prior blood lead level results, and (6) prior written medical opinions concerning you that the employer has. After a medical examination or consultation the physician must prepare a written report which must contain (1) the physician's opinion as to whether you have any medical condition which places you at increased risk of material impairment to health from exposure to lead, (2) any recommended special protective measures to be provided to you, (3) any blood lead level determinations, and (4) any recommended limitation on your use of respirators. This last element must include a determination of whether you can wear a powered air purifying respirator (PAPR) if you are found unable to wear a negative pressure respirator. The medical surveillance program of the interim lead standard may at some point in time serve to notify certain workers that they have acquired a disease or other adverse medical condition as a result of occupational lead exposure. If this is true, these workers might have legal rights to compensation from public agencies, their employers, firms that supply hazardous products to their employers, or other persons. Some states have laws, including worker compensation laws, that disallow a worker who learns of a job-related health impairment to sue, unless the worker sues within a short period of time after learning of the impairment. (This period of time may be a matter of months or years.) An attorney can be consulted about these possibilities. It should be stressed that OSHA is in no way trying to either encourage or discourage claims or lawsuits. However, since results of the standard's medical surveillance program can significantly affect the legal remedies of a worker who has acquired a job-related disease or impairment, it is proper for OSHA to make you aware of this. The medical surveillance section of the standard also contains provisions dealing with chelation. Chelation is the use of certain drugs (administered in pill form or injected into the body) to reduce the amount of lead absorbed in body tissues. Experience accumulated by the medical and scientific communities has largely confirmed the effectiveness of this type of therapy for the treatment of very severe lead poisoning. On the other hand, it has also been established that there can be a long list of extremely harmful side effects associated with the use of chelating agents. The medical community has balanced the advantages and disadvantages resulting from the use of chelating agents in various circumstances and has established when the use of these agents is acceptable. The standard includes these accepted limitations due to a history of abuse of chelation therapy by some lead companies. The most widely used chelating agents are calcium disodium EDTA, (Ca Na2 EDTA), Calcium Disodium Versenate (Versenate), and d-penicillamine (penicillamine or Cupramine). The standard prohibits "prophylactic chelation" of any employee by any person the employer retains, supervises or controls. "Prophylactic chelation" is the routine use of chelating or similarly acting drugs to prevent elevated blood levels in workers who are occupationally exposed to lead, or the use of these drugs to routinely lower blood lead levels to predesignated concentrations believed to be "safe". It should be emphasized that where an employer takes a worker who has no symptoms of lead poisoning and has chelation carried out by a physician (either inside or outside of a hospital) solely to reduce the worker's blood lead level, that will generally be considered prophylactic chelation. The use of a hospital and a physician does not mean that prophylactic chelation is not being performed. Routine chelation to prevent increased or reduce current blood lead levels is unacceptable whatever the setting. The standard allows the use of "therapeutic" or "diagnostic" chelation if administered under the supervision of a licensed physician in a clinical setting with thorough and appropriate medical monitoring. Therapeutic chelation responds to severe lead poisoning where there are marked symptoms. Diagnostic chelation involved giving a patient a dose of the drug then collecting all urine excreted for some period of time as an aid to the diagnosis of lead poisoning. In cases where the examining physician determines that chelation is appropriate, you must be notified in writing of this fact before such treatment. This will inform you of a potentially harmful treatment, and allow you to obtain a second opinion. IX. Medical Removal Protection - Subsection (k) Excessive lead absorption subjects you to increased risk of disease. Medical removal protection (MRP) is a means of protecting you when, for whatever reasons, other methods, such as engineering controls, work practices, and respirators, have failed to provide the protection you need. MRP involves the temporary removal of a worker from his or her regular job to a place of significantly lower exposure without any loss of earnings, seniority, or other employment rights or benefits. The purpose of this program is to cease further lead absorption and allow your body to naturally excrete lead which has previously been absorbed. Temporary medical removal can result from an elevated blood lead level, or a medical opinion. For up to 18 months, or for as long as the job the employee was removed from lasts, protection is provided as a result of either form of removal. The vast majority of removed workers, however, will return to their former jobs long before this eighteen month period expires. You may also be removed from exposure even if your blood lead level is below 50mg/dl if a final medical determination indicates that you temporarily need reduced lead exposure for medical reasons. If the physician who is implementing your employers medical program makes a final written opinion recommending your removal or other special protective measures, your employer must implement the physician's recommendation. If you are removed in this manner, you may only be returned when the doctor indicates that it is safe for you to do so. The standard does not give specific instructions dealing with what an employer must do with a removed worker. Your job assignment upon removal is a matter for you, your employer and your union (if any) to work out consistent with existing procedures for job assignments. Each removal must be accompanied in a manner consistent with existing collective bargaining relationships. Your employer is given broad discretion to implement temporary removals so long as no attempt is made to override existing agreements. Similarly, a removed worker is provided no right to veto an employer's choice which satisfies the standard. In most cases, employers will likely transfer removed employees to other jobs with sufficiently low lead exposure. Alternately, a worker's hours may be reduced so that the time weighted average exposure is reduced, or he or she may be temporarily laid off if no other alternative is feasible. In all of these situation, MRP benefits must be provided during the period of removal - i.e., you continue to receive the same earnings, seniority, and other rights and benefits you would have had if you had not been removed. Earnings includes more than just your base wage; it includes overtime, shift differentials, incentives, and other compensation you would have earned if you had not been removed. During the period of removal you must also be provided with appropriate follow-up medical surveillance. If you were removed because your blood lead level was too high, you must be provided with a monthly blood test. If a medical opinion caused your removal, you must be provided medical tests or examinations that the doctor believes to be appropriate. If you do not participate in this follow up medical surveillance, you may lose your eligibility for MRP benefits. When you are medically eligible to return to your former job, your employer must return you to your "former job status." This means that you are entitled to the position, wages, benefits, etc., you would have had if you had not been removed. If you would still be in your old job if no removal had occurred that is where you go back. If not, you are returned consistent with whatever job assignment discretion your employer would have had if no removal had occurred. MRP only seeks to maintain your rights, not expand them or diminish them. If you are removed under MRP and you are also eligible for worker compensation or other compensation for lost wages, your employer's MRP benefits obligation is reduced by the amount that you actually receive from these other sources. This is also true if you obtain other employment during the time you are laid off with MRP benefits. The standard also covers situations where an employer voluntarily removes a worker from exposure to lead due to the effects of lead on the employee's medical condition, even though the standard does not require removal. In these situations MRP benefits must still be provided as though the standard required removal. Finally, it is important to note that in all cases where removal is required, respirators cannot be used as a substitute. Respirators may be used before removal becomes necessary, but not as an alternative to a transfer to a low exposure job, or to lay-off with MRP benefits. X. Employee Information, Training and Certification - Subsection (l) Your employer is required to provide an information and training program for all employees exposed to lead above the action level or who may suffer skin or eye irritation from lead compounds such as lead arsenate or lead azide. The program must train these employees regarding the specific hazards associated with their work environment, protective measures which can be taken, including the contents of any compliance plan in effect, the danger of lead to their bodies (including their reproductive systems), and their rights under the standard. All employees must be trained prior to initial assignment to areas where there is a possibility of exposure over the action level. This training program must also be provided at least annually thereafter unless further exposure above the action level will not occur. The California Department of Health Services requires the certification of employees and supervisors performing lead related construction activities in residential and public buildings, as defined in Title 17, California Code of Regulations, Division 1, Chapter 8. Lead related construction work is defined in Title 17 as any construction, alteration, painting, demolition, salvage, renovation, repair, or maintenance of any residential or public building, including preparation and cleanup, that, by using or disturbing lead containing material or soil, may result in significant exposure of adults or children to lead. "Public building" means a structure which is generally accessible to the public, including but not limited to, schools, daycare centers, museums, airports, hospitals, stores, convention centers, government facilities, office buildings and any other building which is not an industrial building or a residential building. Where training certification is required, the training must be given by a training provider accredited by the California Department of Health Services. XI. Signs - Subsection (m) The standard requires that the following warning sign be posted in each regulated area or work areas where the exposure to lead exceeds the PEL: WARNING LEAD WORK AREA POISONNO SMOKING OR EATING These signs are to be posted and maintained in a manner which assures that the legend is readily visible. XII. Recordkeeping - Subsection (n) Your employer is required to keep all records of exposure monitoring for airborne lead. These records must include the name and job classification of employees measured, details of the sampling and analytical techniques, the results of this sampling, and the type of respiratory protection being worn by the person sampled. Such records are to be retained for at least 30 years. Your employer is also required to keep all records of biological monitoring and medical examination results. These records must include the names of the employees, the physician's written opinion, and a copy of the results of the examination. Medical records must be preserved and maintained for the duration of employment plus 30 years. However, if the employee's duration of employment is less than one year, the employer need not retain that employee's medical records beyond the period of employment if they are provided to the employee upon termination of employment. Recordkeeping is also required if you are temporarily removed from your job under the medical removal protection program. This record must include your name and social security number, the date of your removal and return, how the removal was or is being accomplished, and whether or not the reason for the removal was an elevated blood lead level. Your employer is required to keep each medical removal record only for as long as the duration of an employee's employment. The standard requires that if you request to see or copy environmental monitoring, blood lead level monitoring, or medical removal records, they must be made available to you or to a representative that you authorize. Your union also has access to these records. Medical records other than BLL's must also be provided upon request to you, to your physician or to any other person whom you may specifically designate. Your union does not have access to your personal medical records unless you authorize their access. XIII. Observation of Monitoring - Subsection (o) When air monitoring for lead is performed at your workplace as required by this standard, your employer must allow you or someone you designate to act as an observer of the monitoring. Observers are entitled to an explanation of the measurement procedure, and to record the results obtained. Since results will not normally be available at the time of the monitoring, observers are entitled to record or receive the results of the monitoring when returned by the laboratory. Your employer is required to provide the observer with any personal protective devices required to be worn by employees working in the area that is being monitored. The employer must require the observer to wear all such equipment and to comply with all other applicable safety and health procedures. XIV. Effective Date - Subsection (p) The standard's effective date was November 4, 1993. Employer obligations under the standard begin as of that date with full implementation of engineering controls as soon as possible but no later than within 4 months, and all other provisions completed as soon as possible, but no later than within 2 months from the effective date. XV. For Additional Information A. A copy of the standard for lead in construction can be obtained free of charge by calling or writing your local Cal/OSHA Office. B. Additional information about the standard, its enforcement, and your employer's compliance can be obtained from the nearest Cal/OSHA Office listed in your telephone directory. Appendix C to s 1532.1 - Medical Surveillance Guidelines Introduction The primary purpose of the Occupational Safety and Health Act of 1970 is to assure, so far as possible, safe and healthful working conditions for every working man and woman. The occupational health standard for lead in construction is designed to protect workers exposed to inorganic lead including metallic lead, all inorganic lead compounds and organic lead soaps. Under this standard occupational exposure to inorganic lead is to be limited to 50mg/m 3 (micrograms per cubic meter) based on an 8 hour time-weighted average (TWA). This permissible exposure limit (PEL) must be achieved through a combination of engineering, work practice and administrative controls to the extent feasible. Where these controls are in place but are found not to reduce employee exposures to or below the PEL, they must be used nonetheless, and supplemented with respirators to meet the 50mg/m 3 exposure limit. The standard also provides for a program of biological monitoring for employees exposed to lead above the action level at any time, and additional medical surveillance for all employees exposed to levels of inorganic lead above 30mg/m 3 (TWA) for more than 30 days per year and whose BLL exceeds 40mg/dl. The purpose of this document is to outline the medical surveillance provisions of the interim standard for inorganic lead in construction, and to provide further information to the physician regarding the examination and evaluation of workers exposed to inorganic lead. Section 1 provides a detailed description of the monitoring procedure including the required frequency of blood testing for exposed workers, provisions for medical removal protection (MRP), the recommended right of the employee to a second medical opinion, and notification and recordkeeping requirements of the employer. A discussion of the requirements for respirator use and respirator monitoring and OSHA's position on prophylactic chelation therapy are also included in this section. Section 2 discusses the toxic effects and clinical manifestations of lead poisoning and effects of lead intoxication on enzymatic pathways in heme synthesis. The adverse effects on both male and female reproductive capacity and on the fetus are also discussed. Section 3 outlines the recommended medical evaluation of the worker exposed to inorganic lead, including details of the medical history, physical examination, and recommended laboratory tests, which are based on the toxic effects of lead as discussed in Section 2. Section 4 provides detailed information concerning the laboratory tests available for the monitoring of exposed workers. Included also is a discussion of the relative value of each test and the limitations and precautions which are necessary in the interpretation of the laboratory results. I. Medical Surveillance and Monitoring Requirements for Workers Exposed to Inorganic Lead Under the standard for inorganic lead in the construction industry, initial medical surveillance consisting of biological monitoring to include blood lead and ZPP level determination shall be provided to employees exposed to lead at or above the action level on any one day. In addition, a program of biological monitoring is to be made available to all employees exposed above the action level at any time and additional medical surveillance is to be made available to all employees exposed to lead above 30mg/m 3 TWA for more than 30 days each year and whose BLL exceeds 40mg/dl. This program consists of periodic blood sampling and medical evaluation to be performed on a schedule which is defined by previous laboratory results, worker complaints or concerns, and the clinical assessment of the examining physician. Under this program, the blood lead level (BLL) of all employees who are exposed to lead above 30mg/m 3 for more than 30 days per year or whose blood lead is above 40mg/dl but exposed for no more than 30 days per year is to be determined at least every two months for the first six months of exposure and every six months thereafter. The frequency is increased to every two months for employees whose last blood lead level was 40mg/dl or above. For employees who are removed from exposure to lead due to an elevated blood lead, a new blood lead level must be measured monthly. A zinc protoporphyrin (ZPP) measurement is strongly recommended on each occasion that a blood lead level measurement is made. An annual medical examination and consultation performed under the guidelines discussed in Section 3 is to be made available to each employee exposed above 30mg/m 3 for more than 30 days per year for whom a blood test conducted at any time during the preceding 12 months indicated a blood lead level at or above 40mg/dl. Also, an examination is to be given to all employees prior to their assignment to an area in which airborne lead concentrations each or exceed the 30mg/m3 for more than 30 days per year. In addition, a medical examination must be provided as soon as possible after notification by an employee that the employee has developed signs and symptoms commonly associated with lead intoxication, that the employee desires medical advice regarding lead exposure and the ability to procreate a healthy child, or that the employee has demonstrated difficulty in breathing during a respirator fitting test or during respirator use. An examination is also to be made available to each employee removed from exposure to lead due to a risk of sustaining material impairment to health, or otherwise limited or specially protected pursuant to medical recommendations. Results of biological monitoring or the recommendations of an examining physician may necessitate removal of an employee from further lead exposure pursuant to the standard's medical removal protection (MRP) program. The object of the MRP program is to provide temporary medical removal to workers either with substantially elevated blood lead levels or otherwise at risk of sustaining material health impairment from continued substantial exposure to lead. Under the standard's ultimate worker removal criteria, a worker is to be removed from any work having an eight hour TWA exposure to lead of 30mg/m 3 when his or her blood lead level reaches 50mg/dl and is confirmed by a second follow-up blood lead level performed within two weeks after the employer receives the results of the first blood sampling test. Return of the employee to his or her job status depends on a worker's blood lead level declining to 40mg/dl. As part of the interim standard, the employer is required to notify in writing each employee whose blood lead level exceeds 40mg/dl. In addition each such employee is to be informed that the standard requires medical removal with MRP benefits, discussed below, when an employee's blood lead level exceeds the above defined limit. In addition to the above blood lead level criterion, temporary worker removal may also take place as a result of medical terminations and recommendations. Written medical opinions must be prepared after each examination pursuant to the standard. If the examining physician includes a medical finding, determination or opinion that the employee has a medical condition which places the employee at increased risk of material health impairment from exposure to lead, then the employee must be removed from exposure to lead at or above 30mg/m 3. Alternatively, if the examining physician recommends special protective measures for an employee (e.g., use of a powered air purifying respirator) or recommends limitations on an employee's exposure to lead, then the employer must implement these recommendations. Recommendations may be more stringent than the specific provisions of the standard. The examining physician, therefore, is given broad flexibility to tailor special protective procedures to the needs of individual employees. This flexibility extends to the evaluation and management of pregnant workers and male and female workers who are planning to raise children. Based on the history, physical examination, and laboratory studies, the physician might recommend special protective measures or medical removal for an employee who is pregnant or who is planning to conceive a child when, in the physician's judgment, continued exposure to lead at the current job would pose a significant risk. The return of the employee to his or her former job status, or the removal of special protections or limitations, depends upon the examining physician determining that the employee is no longer at increased risk of material impairment or that special measures are no longer needed. During the period of any form of special protection or removal, the employer must maintain the worker's earnings, seniority, and other employment rights and benefits (as though the worker had not been removed) for a period of up to 18 months or for as long as the job the employee was removed from lasts if less than 18 months. This economic protection will maximize meaningful worker participation in the medical surveillance program, and is appropriate as part of the employer's overall obligation to provide a safe and healthful workplace. The provisions of MRP benefits during the employee's removal period may, however, be conditioned upon participation in medical surveillance. The lead standard provides for a multiple physician review in cases where the employee wishes a second opinion concerning potential lead poisoning or toxicity. If an employee wishes a second opinion, he or she can make an appointment with a physician of his or her choice. This second physician will review the findings, recommendations or determinations of the first physician and conduct any examinations, consultations or tests deemed necessary in an attempt to make a final medical determination. If the first and second physicians do not agree in their assessment they must try to resolve their differences. If they cannot reach an agreement then they must designate a third physician to resolve the dispute. The employer must provide examining and consulting physicians with the following specific information: A copy of the lead regulations and all appendices, a description of the employee's duties as related to exposure, the exposure level or anticipated level to lead and any other toxic substances (if applicable), a description of personal protective equipment used, blood lead levels, and all prior written medical opinions regarding the employee in the employer's possession or control. The employer must also obtain from the physician and provide the employee with a written medical opinion containing blood lead levels, the physician's opinion as to whether the employee is at risk of material impairment to health, any recommended protective measures for the employee if further exposure is permitted, as well as any recommended limitations upon an employee's use of respirators. Employers must instruct each physician not to reveal to the employer in writing or in any other way his or her findings, laboratory results, or diagnoses which are felt to be unrelated to occupational lead exposure. They must also instruct each physician to advise the employee of any occupationally or non-occupationally related medical condition requiring further treatment or evaluation. The standard provides for the use of respirators where engineering and other primary controls are not effective. However, the use of respirator protection shall not be used in lieu of temporary medical removal due to elevated blood lead levels or findings that an employee is at risk of material health impairment. This is based on the numerous inadequacies of respirators including skin rash where the facepiece makes contact with the skin, unacceptable stress to breathing in some workers with underlying cardiopulmonary impairment, difficulty in providing adequate fit, the tendency for respirators to create additional hazards by interfering with vision, hearing, and mobility, and the difficulties of assuring the maximum effectiveness of a complicated work practice program involving respirators. Respirators do, however, serve a useful function where engineering and work practice controls are inadequate by providing supplementary, interim, or short-term protection, provided they are properly selected for the environment in which the employee will be working, properly fitted to the employee, maintained and cleaned periodically, and worn by the employee when required. In its standard on occupational exposure to inorganic lead in the construction industry, OSHA has prohibited prophylactic chelation. Diagnostic and therapeutic chelation are permitted only under the supervision of a licensed physician with appropriate medical monitoring in an acceptable clinical setting. The decision to initiate chelation therapy must be made on an individual basis and take into account the severity of symptoms felt to be a result of lead toxicity along with blood lead levels, ZPP levels, and other laboratory tests as appropriate. EDTA and penicillamine which are the primary chelating agents used in the therapy of occupational lead poisoning have significant potential side effects and their use must be justified on the basis of expected benefits to the worker. Unless frank and severe symptoms are prevent, therapeutic chelation is not recommended, given the opportunity to remove a worker from exposure and allow the body to naturally excrete accumulated lead. As a diagnostic aid, the chelation mobilization test using CA-EDTA has limited applicability. According to some investigators, the test can differentiate between lead-induced and other nephropathies. The test may also provide an estimation of the mobile fraction of the total body lead burden. Employers are required to assure that accurate records are maintained on exposure assessment, including environmental monitoring, medical surveillance, and medical removal for each employee. Exposure assessment records must be kept for at least 30 years. Medical surveillance records must be kept for the duration of employment plus 30 years except in cases where the employment was less than one year. If duration of employment is less than one year, the employer need not retain this record beyond the term of employment if the record is provided to the employee upon termination of employment. Medical removal records also must be maintained for the duration of employment. All records required under the standard must be made available upon request to the Chief and the National Institute for Occupational Safety and Health. Employers must also make environmental and biological monitoring and medical removal records available to affected employees and to former employees or their authorized employee representatives. Employees or their specifically designated representatives have access to their entire medical surveillance records. In addition, the standard requires that the employer inform all workers exposed to lead at or above 30mg/m 3 of the provisions of the standard and all its appendices, the purpose and description of medical surveillance and provisions for medical removal protection if temporary removal is required. An understanding of the potential health effects of lead exposure by all exposed employees along with full understanding of their rights under the lead standard is essential for an effective monitoring program. II. Adverse Health Effects of Inorganic Lead Although the toxicity of lead has been known for 2,000 years, the knowledge of the complex relationship between lead exposure and human response is still being refined. Significant research into the toxic properties of lead continues throughout the world, and it should be anticipated that our understanding of thresholds of effects and margins of safety will be improved in future years. The provisions of the lead standard are founded on two prime medical judgments: First, the prevention of adverse health effects from exposure to lead throughout a working lifetime requires that worker blood lead levels be maintained at or below 40mg/dl and second, the blood lead levels of workers, male or female, who intend to parent in the near future should be maintained below 30mg/dl to minimize adverse reproductive health effects to the parents and developing fetus. The adverse effects of lead on reproduction are being actively researched and Cal/OSHA encourages the physician to remain abreast of recent developments in the area to best advise pregnant workers or workers planning to conceive children. The spectrum of health effects caused by lead exposure can be subdivided into five developmental stages: Normal, physiological changes of uncertain significance, pathophysiological changes, overt symptoms (morbidity), and mortality. Within this process there are no sharp distinctions, but rather a continuum of effects. Boundaries between categories overlap due to the wide variation of individual responses and exposures in the working population. OSHA's development of the lead standard focused on pathophysiological changes as well as later stages of disease. 1. Heme Synthesis Inhibition. The earliest demonstrated effect of lead involves its ability to inhibit at least two enzymes of the heme synthesis pathway at very low blood levels. Inhibition of delta aminolevulinic acid dehydrase (ALA-D) which catalyzes the conversion of delta-aminolevulinic acid (ALA) to protoporphyrin is observed at a blood lead level below 20mg/dl. At a blood lead level of 40mg/dl, more than 20% of the population would have 70% inhibition of ALA-D. There is an exponential increase in ALA excretion at blood lead levels greater than 40mg/dl. Another enzyme, ferrochelatase, is also inhibited at low blood lead levels. Inhibition of ferrochelatase leads to increased free erythrocyte protoporphyrin (FEP) in the blood which can then bind to zinc to yield zinc protoporphyrin. At a blood lead level of 50mg/dl or greater, nearly 100% of the population will have an increase in FEP. There is also an exponential relationship between blood lead levels greater than 40mg/dl and the associated ZPP level, which has led to the development of the ZPP screening test for lead exposure. While the significance of these effects is subject to debate, it is Cal/OSHA's position that these enzyme disturbances are early stages of a disease process which may eventually result in the clinical symptoms of lead poisoning. Whether or not the effects do progress to the later stages of clinical disease, disruption of these enzyme processes over a working lifetime is considered to be a material impairment of health. One of the eventual results of lead-induced inhibition of enzymes in the heme synthesis pathway is anemia which can be asymptomatic if mild but associated with a wide array of symptoms including dizziness, fatigue, and tachycardia when more severe. Studies have indicated that lead levels as low as 50mg/dl can be associated with a definite decreased hemoglobin, although most cases of lead-induced anemia, as well as shortened red-cell survival times, occur at lead levels exceeding 80mg/dl. Inhibited hemoglobin synthesis is more common in chronic cases whereas shortened erythrocyte life span is more common in acute cases. In lead-induced anemias, there is usually a reticulocytosis along with the presence of basophilic stippling, and ringed sideroblasts, although none of the above are pathognomonic for lead-induced anemia. 2. Neurological Effects. Inorganic lead has been found to have toxic effects on both the central and peripheral nervous systems. The earliest stages of lead-induced central nervous system effects first manifest themselves in the form of behavioral disturbances and central nervous system symptoms including irritability, restlessness, insomnia and other sleep disturbances, fatigue, vertigo, headache, poor memory, tremor, depression, and apathy. With more severe exposure, symptoms can progress to drowsiness, stupor, hallucinations, delirium, convulsions and coma. The most severe and acute form of lead poisoning which usually follows ingestion or inhalation of large amounts of lead is acute encephalopathy which may arise precipitously with the onset of intractable seizures, coma, cardiorespiratory arrest, and death within 48 hours. While there is disagreement about what exposure levels are needed to produce the earliest symptoms, most experts agree that symptoms definitely can occur at blood lead levels of 60mg/dl whole blood and therefore recommend a 40mg/dl maximum. The central nervous system effects frequently are not reversible following discontinued exposure or chelation therapy and when improvement does occur, it is almost always only partial. The peripheral neuropathy resulting from lead exposure characteristically involves only motor function with minimal sensory damage and has a marked predilection for the extensor muscles of the most active extremity. The peripheral neuropathy can occur with varying degrees of severity. The earliest and mildest form which can be detected in workers with blood lead levels as low as 50mg/dl is manifested by slowing of motor nerve conduction velocity often without clinical symptoms. With progression of the neuropathy there is development of painless extensor muscle weakness usually involving the extensor muscles of the fingers and hand in the most active upper extremity, followed in severe cases by wrist drop or, much less commonly, foot drop. In addition to slowing of nerve conduction, electromyographical studies in patients with blood lead levels greater than 50mg/dl have demonstrated a decrease in the number of acting motor unit potentials, an increase in the duration of motor unit potentials, and spontaneous pathological activity including fibrillations and fasciculations. Whether these effects occur at levels of 40mg/dl is undetermined. While the peripheral neuropathies can occasionally be reversed with therapy, again such recovery is not assured particularly in the more severe neuropathies and often improvement is only partial. The lack of reversibility is felt to be due in part to segmental demyelination. 3. Gastrointestinal. Lead may also affect the gastrointestinal system producing abdominal colic or diffuse abdominal pain, constipation, obstipation, diarrhea, anorexia, nausea and vomiting. Lead colic rarely develops at blood lead levels below 80mg/dl. 4. Renal. Renal toxicity represents one of the most serious health effects of lead poisoning. In the early stages of disease nuclear inclusion bodies can frequently be identified in proximal renal tubular cells. Renal function remains normal and the changes in this stage are probably reversible. With more advanced disease there is progressive interstitial fibrosis and impaired renal function. Eventually extensive interstitial fibrosis ensues with sclerotic glomeruli and dilated and atrophied proximal tubules; all represent end stage kidney disease. Azotemia can be progressive, eventually resulting in frank uremia necessitating dialysis. There is occasionally associated hypertension and hyperuricemia with or without gout. Early kidney disease is difficult to detect. The urinalysis is normal in early lead nephropathy and the blood urea nitrogen and serum creatinine increase only when two-thirds of kidney function is lost. Measurement of creatinine clearance can often detect earlier disease as can other methods of measurement of glomerular filtration rate. An abnormal Ca-EDTA mobilization test has been used to differentiate between lead-induced and other nephropathies, but this procedure is not widely accepted. A form of Fanconi syndrome with aminoaciduria, glycosuria, and hyperphosphaturia indicating severe injury to the proximal renal tubules is occasionally seen in children. 5. Reproductive effects. Exposure to lead can have serious effects on reproductive function in both males and females. In male workers exposed to lead there can be a decrease in sexual drive, impotence, decreased ability to produce healthy sperm, and sterility. Malformed sperm (teratospermia), decreased number of sperm (hypospermia), and sperm with decreased motility (asthenospermia) can all occur. Teratospermia has been noted at mean blood lead levels of 53mg/dl and hypospermia and athenospermia at 41mg/dl. Furthermore, there appears to be a dose-response relationship for teratospermia in lead exposed workers. Women exposed to lead may experience menstrual disturbances including dysmenorrhea, menorrhagia and amenorrhea. Following exposure to lead, women have a higher frequency of sterility, premature births, spontaneous miscarriages, and stillbirths. Germ cells can be affected by lead and cause genetic damage in the egg or sperm cells before conception and result in failure to implant, miscarriage, stillbirth, or birth defects. Infants of mothers with lead poisoning have a higher mortality during the first year and suffer from lowered birth weights, slower growth, and nervous system disorders. Lead can pass through the placental barrier and lead levels in the mother's blood are comparable to concentrations of lead in the umbilical cord at birth. Transplacental passage becomes detectable at 12-14 weeks of gestation and increases until birth. There is little direct data on damage to the fetus from exposure to lead but it is generally assumed that the fetus and newborn would be at least as susceptible to neurological damage as young children. Blood lead levels of 50- 60mg/dl in children can cause significant neurobehavioral impairments and there is evidence of hyperactivity at blood levels as low as 25mg/dl. Given the overall body of literature concerning the adverse health effects of lead in children, Cal/OSHA feels that the blood lead level in children should be maintained below 30mg/dl with a population mean of 15mg/dl. Blood lead levels in the fetus and newborn likewise should not exceed 30mg/dl. Because of lead's ability to pass through the placental barrier and also because of the demonstrated adverse effects of lead on reproductive function in both the male and female as well as the risk of genetic damage of lead on both the ovum and sperm, Cal/OSHA recommends a 30mg/dl maximum permissible blood lead level in both males and females who wish to bear children. 6. Other toxic effects. Debate and research continue on the effects of lead on the human body. Hypertension has frequently been noted in occupationally exposed individuals although it is difficult to assess whether this is due to lead's adverse effects on the kidney or if some other mechanism is involved. Vascular and electrocardiographic changes have been detected but have not been well characterized. Lead is thought to impair thyroid function and interfere with the pituitary-adrenal axis, but again these effects have not been well defined. III. Medical Evaluation The most important principle in evaluating a worker for any occupational disease including lead poisoning is a high index of suspicion on the part of the examining physician. As discussed in Section 2, lead can affect numerous organ systems and produce a wide array of signs and symptoms, most of which are non-specific and subtle in nature at least in the early stages of disease. Unless serious concern for lead toxicity is present, many of the early clues to diagnosis may easily be overlooked. The crucial initial step in the medical evaluation is recognizing that a worker's employment can result in exposure to lead. The worker will frequently be able to define exposures to lead and lead containing materials but often will not volunteer this information unless specifically asked. In other situations the worker may not know of any exposures to lead but the suspicion might be raised on the part of the physician because of the industry or occupation of the worker. Potential occupational exposure to lead and its compounds occur in many occupations in the construction industry, including demolition and salvaging operations, removal or encapsulation of materials containing lead, construction, alteration, repair or renovation of structures containing lead, transportation, disposal, storage or containment of lead or lead-containing materials on construction sites, and maintenance operations associated with construction activities. Once the possibility for lead exposure is raised, the focus can then be directed toward eliciting information from the medical history, physical exam, and finally from laboratory data to evaluate the worker for potential lead toxicity. A complete and detailed work history is important in the initial evaluation. A listing of all previous employment with information on job description, exposure to fumes or dust, known exposures to lead or other toxic substances, a description of any personal protective equipment used, and previous medical surveillance should all be included in the worker's record. Where exposure to lead is suspected, information concerning on-the-job personal hygiene, smoking or eating habits in work areas, laundry procedures, and use of any protective clothing or respiratory protection equipment should be noted. A complete work history is essential in the medical evaluation of a worker with suspected lead toxicity, especially when long term effects such as neurotoxicity and nephrotoxicity are considered. The medical history is also of fundamental importance and should include a listing of all past and current medical conditions, current medications including proprietary drug intake, previous surgeries and hospitalizations, allergies, smoking history, alcohol consumption, and also non-occupational lead exposures such as hobbies (hunting, riflery). Also known childhood exposures should be elicited. Any previous history of hematological, neurological, gastrointestinal, renal, psychological, gynecological, genetic, or reproductive problems should be specifically noted. A careful and complete review of systems must be performed to assess both recognized complaints and subtle or slowly acquired symptoms which the worker might not appreciate as being significant. The review of symptoms should include the following: 1. General - weight loss, fatigue, decreased appetite. 2. Head, Eyes, Ears, Nose, Throat (HEENT) - headaches, visual disturbances or decreased visual acuity, hearing deficits or tinnitus, pigmentation of the oral mucosa, or metallic taste in mouth. 3. Cardio-pulmonary - shortness of breath, cough, chest pains, palpitations, or orthopnea. 4. Gastrointestinal - nausea, vomiting, heartburn, abdominal pain, constipation or diarrhea. 5. Neurologic - irritability, insomnia, weakness (fatigue), dizziness, loss of memory, confusion, hallucinations, incoordination, ataxia, decreased strength in hands or feet, disturbances in gait, difficulty in climbing stairs, or seizures. 6. Hematologic - pallor, easy fatigability, abnormal blood loss, melena. 7. Reproductive (male and female and spouse where relevant) - history of infertility, impotence, loss of libido, abnormal menstrual periods, history of miscarriages, stillbirths, or children with birth defects. 8. Musculo-skeletal - muscle and joint pains. The physical examination should emphasize the neurological, gastrointestinal, and cardiovascular systems. The worker's weight and blood pressure should be recorded and the oral mucosa checked for pigmentation characteristic of a possible Burtonian or lead line on the gingiva. It should be noted, however, that the lead line may not be present even in severe lead poisoning if good oral hygiene is practiced. The presence of pallor on skin examination may indicate an anemia which, if severe, might also be associated with a tachycardia. If an anemia is suspected, an active search for blood loss should be undertaken including potential blood loss through the gastrointestinal tract. A complete neurological examination should include an adequate mental status evaluation including a search for behavioral and psychological disturbances, memory testing, evaluation for irritability, insomnia, hallucinations, and mental clouding. Gait and coordination should be examined along with close observation for tremor. A detailed evaluation of peripheral nerve function including careful sensory and motor function testing is warranted. Strength testing particularly of extensor muscle groups of all extremities is of fundamental importance. Cranial nerve evaluation should also be included in the routine examination. The abdominal examination should include auscultation for bowel sounds and abdominal bruits and palpation for organomegaly, masses, and diffuse abdominal tenderness. Cardiovascular examination should evaluate possible early signs of congestive heart failure. Pulmonary status should be addressed particularly if respirator protection is contemplated. As part of the medical evaluation, the interim lead standard requires the following laboratory studies: 1. Blood lead level; 2. Hemoglobin and hematocrit determinations, red cell indices, and examination of the peripheral blood smear to evaluate red blood cell morphology; 3. Blood urea nitrogen; 4. Serum creatinine; 5. Routine urinalysis with microscopic examination; 6. A zinc protoporphyrin level. In additional to the above, the physician is authorized to order any further laboratory or other tests which he or she deems necessary in accordance with sound medical practice. The evaluation must also include pregnancy testing or laboratory evaluation of male fertility if requested by the employee. Additional tests which are probably not warranted on a routine basis but may be appropriate when blood lead and ZPP levels are equivocal include delta aminolevulinic acid and coproporphyrin concentrations in the urine, and dark-field illumination for detection of basophilic stippling in red blood cells. If an anemia is detected further studies including a careful examination of the peripheral smear, reticulocyte count, stool for occult blood, serum iron, total iron binding capacity, bilirubin, and, if appropriate, vitamin B12 and folate may be of value in attempting to identify the cause of the anemia. If a peripheral neuropathy is suspected, nerve conduction studies are warranted both for diagnosis and as a basis to monitor any therapy. If renal disease is questioned, a 24 hour urine collection for creatinine clearance, protein, and electrolytes may be indicated. Elevated uric acid levels may result from lead-induced renal disease and a serum uric acid level might be performed. An electrocardiogram and chest x-ray may be obtained as deemed appropriate. Sophisticated and highly specialized testing should not be done routinely and where indicated should be under the direction of a specialist. IV. Laboratory Evaluation The blood lead level at present remains the single most important test to monitor lead exposure and is the test used in the medical surveillance program under the lead standard to guide employee medical removal. The ZPP has several advantages over the blood lead level. Because of its relatively recent development and the lack of extensive data concerning its interpretation, the ZPP currently remains an ancillary test. This section will discuss the blood lead level and ZPP in detail and will outline their relative advantages and disadvantages. Other blood tests currently available to evaluate lead exposure will also be reviewed. The blood lead level is a good index of current or recent lead absorption when there is no anemia present and when the worker has not taken any chelating agents. However, blood lead levels along with urinary lead levels do not necessarily indicate the total body burden of lead and are not adequate measures of past exposure. One reason for this is that lead has a high affinity for bone and up to 90% of the body's total lead is deposited there. A very important component of the total lead body burden is lead in soft tissue (liver, kidney, and brain). This fraction of the lead body burden, the biologically active lead, is not entirely reflected by blood lead levels since it is a function of the dynamics of lead absorption, distribution, deposition in bone and excretion. Following discontinuation of exposure to lead, the excess body burden is only slowly mobilized from bone and other relatively stable body stores and excreted. Consequently, a high blood lead level may only represent recent heavy exposure to lead without a significant total body excess and likewise a low blood lead level does not exclude an elevated total body burden of lead. Also due to its correlation with recent exposures, the blood lead level may vary considerably over short time intervals. To minimize laboratory error and erroneous results due to contamination, blood specimens must be carefully collected after thorough cleaning of the skin with appropriate methods using lead-free blood containers and analyzed by a reliable laboratory. Under the standard, samples must be analyzed in laboratories which are approved by OSHA. Analysis is to be made using atomic absorption spectrophotometry, anodic stripping voltammetry or any method which meets the accuracy requirements set forth by the standard. The determination of lead in urine is generally considered a less reliable monitoring technique than analysis of whole blood primarily due to individual variability in urinary excretion capacity as well as the technical difficulty of obtaining accurate 24 hour urine collections. In addition, workers with renal insufficiency, whether due to lead or some other cause, may have decreased lead clearance and consequently urine lead levels may underestimate the true lead burden. Therefore, urine lead levels should not be used as a routine test. The zinc protoporphyrin test, unlike the blood lead determination, measures an adverse metabolic effect of lead and as such is a better indicator of lead toxicity than the level of blood lead itself. The level of ZPP reflects lead absorption over the preceding 3 to 4 months, and therefore is a better indicator of lead body burden. The ZPP requires more time than the blood lead to read significantly elevated levels; the return to normal after discontinuing lead exposure is also slower. Furthermore, the ZPP test is simpler, faster, and less expensive to perform and no contamination is possible. Many investigators believe it is the most reliable means of monitoring chronic lead absorption. Zinc protoporphyrin results from the inhibition of the enzyme ferrochelatase which catalyzes the insertion of an iron molecule into the protoporphyrin molecule, which then becomes heme. If iron is not inserted into the molecule then zinc, having a greater affinity for protoporphyrin, takes the place of the iron, forming ZPP. An elevation in the level of circulating ZPP may occur at blood lead levels as low as 20-30mg/dl in some workers. Once the blood lead level has reached 40mg/dl there is more marked rise in the ZPP value from its normal range of less than 100mg/dl100 ml. Increases in blood lead levels beyond 40mg/100 g are associated with exponential increases in ZPP. Whereas blood lead levels fluctuate over short time spans, ZPP levels remain relatively stable. ZPP is measured directly in red blood cells and is present for the cell's entire 120 day life-span. Therefore, the ZPP level in blood reflects the average ZPP production over the previous 3-4 months and consequently the average lead exposure during that time interval. It is recommended that a hematocrit be determined whenever a confirmed ZPP of 50mg/100 ml whole blood is obtained to rule out a significant underlying anemia. If the ZPP is in excess of 100mg/100 ml and not associated with abnormal elevations in blood lead levels, the laboratory should be checked to be sure that blood leads were determined using atomic absorption spectrophotometry anodic stripping voltammetry, or any method which meets the accuracy requirements set forth by the standard by an OSHA approved laboratory which is experienced in lead level determinations. Repeat periodic blood lead studies should be obtained in all individuals with elevated ZPP levels to be certain that an associated elevated blood lead level has not been missed due to transient fluctuations in blood leads. ZPP has a characteristic fluorescence spectrum with a peak at 594 nm which is detectable with a hematofluorimeter. The hematofluorimeter is accurate and portable and can provide on-site, instantaneous results for workers who can be frequently tested via a finger prick. However, careful attention must be given to calibration and quality control procedures. Limited data on blood lead-ZPP correlations and the ZPP levels which are associated with the adverse health effects discussed in Section 2 are the major limitations of the test. Also it is difficult to correlate ZPP levels with environmental exposure and there is some variation of response with age and sex. Nevertheless, the ZPP promises to be an important diagnostic test for the early detection of lead toxicity and its value will increase as more data is collected regarding its relationship to other manifestations of lead poisoning. Levels of delta-aminolevulinic acid (ALA) in the urine are also used as a measure of lead exposure. Increasing concentrations of ALA are believed to result from the inhibition of the enzyme delta-aminolevulinic acid dehydrase (ALA-D). Although the test is relatively easy to perform, inexpensive, and rapid, the disadvantages include variability in results, the necessity to collect a complete 24 hour urine sample which has a specific gravity greater than 1.010, and also the fact that ALA decomposes in the presence of light. The pattern of porphyrin excretion in the urine can also be helpful in identifying lead intoxication. With lead poisoning, the urine concentrations of coproporphyrins I and II, porphobilinogen and uroporphyrin I rise. The most important increase, however, is that of coproporphyrin III; levels may exceed 5,000mg/1 in the urine in lead poisoned individuals, but its correlation with blood lead levels and ZPP are not as good as those of ALA. Increases in urinary porphyrins are not diagnostic of lead toxicity and may be seen in porphyria, some liver diseases, and in patients with high reticulocyte counts. Summary. The standard for inorganic lead in the construction industry places significant emphasis on the medical surveillance of all workers exposed to levels of inorganic lead above 30mg/m 3 TWA. The physician has a fundamental role in this surveillance program, and in the operation of the medical removal protection program. Even with adequate worker education on the adverse health effects of lead and appropriate training in work practices, personal hygiene and other control measures, the physician has a primary responsibility for evaluating potential lead toxicity in the worker. It is only through a careful and detailed medical and work history, a complete physical examination and appropriate laboratory testing that an accurate assessment can be made. Many of the adverse health effects of lead toxicity are either irreversible or only partially reversible and therefore early detection of disease is very important. This document outlines the medical monitoring program as defined by the occupational safety and health standard for inorganic lead. It reviews the adverse health effects of lead poisoning and describes the important elements of the history and physical examinations as they relate to these adverse effects. Finally, the appropriate laboratory testing for evaluating lead exposure and toxicity is presented. It is hoped that this review and discussion will give the physician a better understanding of the OSHA standard with the ultimate goal of protecting the health and well-being of the worker exposed to lead under his or her care.

Reference: Sections 142.3 and 6717, Labor Code. s 1532.2. Chromium (VI). (a) Scope. (1) This standard applies to occupational exposures to chromium (VI) in all forms and compounds in construction, except: (2) Exposures that occur in the application of pesticides regulated by the California Department of Pesticide Regulation, the U.S. Environmental Protection Agency or another Federal government agency (e.g., the treatment of wood with preservatives); (3) Exposures to portland cement; or (4) Where the employer has objective data demonstrating that a material containing chromium or a specific process, operation, or activity involving chromium cannot release dusts, fumes, or mists of chromium (VI) in concentrations at or above 0.5 mg/m 3 as an 8-hour time-weighted average (TWA) under any expected conditions of use. Note:Exposures to strontium chromate shall comply with the provisions of Section 5155 in addition to this standard. (b) Definitions. For the purposes of this section the following definitions apply: Action level means a concentration of airborne chromium (VI) of 2.5 micrograms per cubic meter of air (2.5 mg/m 3) calculated as an 8-hour time-weighted average (TWA). Chromium (VI) [hexavalent chromium or Cr(VI)] means chromium with a valence of positive six, in any form and in any compound. Emergency means any occurrence that results, or is likely to result, in an uncontrolled release of chromium (VI). If an incidental release of chromium (VI) can be controlled at the time of release by employees in the immediate release area, or by maintenance personnel, it is not an emergency. Employee exposure means the exposure to airborne chromium (VI) that would occur if the employee were not using a respirator. High efficiency particulate air [HEPA] filter means a filter that is at least 99.97 percent efficient in removing mono dispersed particles of 0.3 micrometers in diameter or larger. Historical monitoring data means data from chromium (VI) monitoring conducted prior to September 19, 2006, obtained during work operations conducted under workplace conditions closely resembling the processes, types of material, control methods, work practices, and environmental conditions in the employer's current operations. Objective data means information such as air monitoring data from industry-wide surveys or calculations based on the composition or chemical and physical properties of a substance demonstrating the employee exposure to chromium (VI) associated with a particular product or material or a specific process, operation, or activity. The data must reflect workplace conditions closely resembling the processes, types of material, control methods, work practices, and environmental conditions in the employer's current operations. Physician or other licensed health care professional [PLHCP] is an individual whose legally permitted scope of practice (i.e., license, registration, or certification) allows him or her to independently provide or be delegated the responsibility to provide some or all of the particular health care services required by subsection (i) of this section. "This section" means this 1532.2 Chromium (VI) standard. (c) Permissible exposure limit (PEL). The employer shall ensure that no employee is exposed to an airborne concentration of chromium (VI) in excess of 5 micrograms per cubic meter of air (5 mg/m 3), calculated as an 8-hour time-weighted average (TWA). (d) Exposure determination. (1) General. Each employer who has a workplace or work operation covered by this section shall determine the 8-hour TWA exposure for each employee exposed to chromium (VI). This determination shall be made in accordance with either subsection (d)(2) or subsection (d)(3) of this section. (2) Scheduled monitoring option. (A) The employer shall perform initial monitoring to determine the 8-hour TWA exposure for each employee on the basis of a sufficient number of personal breathing zone air samples to accurately characterize full shift exposure on each shift, for each job classification, in each work area. Where an employer does representative sampling instead of sampling all employees in order to meet this requirement, the employer shall sample the employee(s) expected to have the highest chromium (VI) exposures. (B) If initial monitoring indicates that employee exposures are below the action level, the employer may discontinue monitoring for those employees whose exposures are represented by such monitoring. (C) If monitoring reveals employee exposures to be at or above the action level, the employer shall perform periodic monitoring at least every six months. (D) If monitoring reveals employee exposures to be above the PEL, the employer shall perform periodic monitoring at least every three months. (E) If periodic monitoring indicates that employee exposures are below the action level, and the result is confirmed by the result of another monitoring taken at least seven days later, the employer may discontinue the monitoring for those employees whose exposures are represented by such monitoring. (F) The employer shall perform additional monitoring when there has been any change in the production process, raw materials, equipment, personnel, work practices, or control methods that may result in new or additional exposures to chromium (VI), or when the employer has any reason to believe that new or additional exposures have occurred. (3) Performance-oriented option. The employer shall determine the 8-hour TWA exposure for each employee on the basis of any combination of air monitoring data, historical monitoring data, or objective data sufficient to accurately characterize employee exposure to chromium (VI). (4) Employee notification of determination results. (A) Where the exposure determination indicates that employee exposure exceeds the PEL, as soon as possible but not more than 5 working days later the employer shall either post the results in an appropriate location that is accessible to all affected employees or shall notify each affected employee individually in writing of the results. (B) Whenever the exposure determination indicates that employee exposure is above the PEL, the employer shall describe in the written notification the corrective action being taken to reduce employee exposure to or below the PEL. (5) Accuracy of measurement. Where air monitoring is performed to comply with the requirements of this section, the employer shall use a method of monitoring and analysis that can measure chromium (VI) to within an accuracy of plus or minus 25 percent (+/- 25%) and can produce accurate measurements to within a statistical confidence level of 95 percent for airborne concentrations at or above the action level. (6) Observation of monitoring. (A) Where air monitoring is performed to comply with the requirements of this section, the employer shall provide affected employees or their designated representatives an opportunity to observe any monitoring of employee exposure to chromium (VI). (B) When observation of monitoring requires entry into an area where the use of protective clothing or equipment is required, the employer shall provide the observer with clothing and equipment and shall assure that the observer uses such clothing and equipment and complies with all other applicable safety and health procedures. (e) Methods of compliance. (1) Engineering and work practice controls. (A) Except as permitted in subsection (e)(1)(B) of this section, the employer shall use engineering and work practice controls to reduce and maintain employee exposure to chromium (VI) to or below the PEL unless the employer can demonstrate that such controls are not feasible. Wherever feasible engineering and work practice controls are not sufficient to reduce employee exposure to or below the PEL, the employer shall use them to reduce employee exposure to the lowest levels achievable, and shall supplement them by the use of respiratory protection that complies with the requirements of subsection (f) of this section. (B) Where the employer can demonstrate that a process or task does not result in any employee exposure to chromium (VI) above the PEL for 30 or more days per year (12 consecutive months), the requirement to implement engineering and work practice controls to achieve the PEL does not apply to that process or task. (2) Prohibition of rotation. The employer shall not rotate employees to different jobs to achieve compliance with the PEL. (f) Respiratory protection. (1) General. The employer shall provide respiratory protection for employees during: (A) Periods necessary to install or implement feasible engineering and work practice controls; (B) Work operations, such as maintenance and repair activities, for which engineering and work practice controls are not feasible; (C) Work operations for which an employer has implemented all feasible engineering and work practice controls and such controls are not sufficient to reduce exposures to or below the PEL; (D) Work operations where employees are exposed above the PEL for fewer than 30 days per year, and the employer has elected not to implement engineering and work practice controls to achieve the PEL; or (E) Emergencies. (2) Respiratory protection program. Where respirator use is required by this section, the employer shall institute a respiratory protection program in accordance with Section 5144. (g) Protective work clothing and equipment. (1) Provision and use.

For the purposes of this section, the requirement that an employer return an employee to his or her former job status is not intended to expand upon or restrict any rights an employee has or could have had, absent temporary medical removal, to a specific job classification or position under the terms of a collective bargaining agreement. (C) Removal of other employee special protective measure or limitations. The employer shall remove any limitations placed on an employee or end any special protective measures provided to an employee pursuant to a final medical determination when a subsequent final medical determination indicates that the limitations or special protective measures are no longer necessary. (D) Employer options pending a final medical determination. Where the physician review mechanism used pursuant to the medical surveillance provisions of this section, has not yet resulted in a final medical determination with respect to an employee, the employer shall act as follows: 1. Removal. The employer may remove the employee from exposure to MDA, provide special protective measures to the employee, or place limitations upon the employee, consistent with the medical findings, determinations, or recommendations of the physician who has reviewed the employee's health status. 2. Return. The employer may return the employee to his or her former job status, and end any special protective measures provided to the employee, consistent with the medical findings, determinations, or recommendations of any of the physicians who have reviewed the employee's health status, with two exceptions: a. If the initial removal, special protection, or limitation of the employee resulted from a final medical determination which differed from the findings, determinations, or recommendations of the initial physician; or b. The employee has been on removal status for the preceding six months as a result of exposure to MDA, then the employer shall await a final medical determination. (E) Medical removal protection benefits. 1. Provisions of medical removal protection benefits. The employer shall provide to an employee up to six (6) months of medical removal protection benefits on each occasion that an employee is removed from exposure to MDA or otherwise limited pursuant to this section. 2. Definition of medical removal protection benefits. For the purposes of this section, the requirement that an employer provide medical removal protection benefits means that the employer shall maintain the earnings, seniority, and other employment rights and benefits of an employee as though the employee had not been removed from normal exposure to MDA or otherwise limited. 3. Follow-up medical surveillance during the period of employee removal or limitations. During the period of time that an employee is removed from normal exposure to MDA or otherwise limited, the employer may condition the provision of medical removal protection benefits upon the employee's participation in follow-up medical surveillance made available pursuant to this section. 4. Workers' compensation claims. If a removed employee files a claim for workers' compensation payments for a MDA-related disability, then the employer shall continue to provide medical removal protection benefits pending disposition of the claim. To the extent that an award is made to the employee for earnings lost during the period of removal, the employer's medical removal protection obligation shall be reduced by such amount. The employer shall receive no credit for workers' compensation payments received by the employee for treatment-related expenses. 5. Other credits. The employer's obligation to provide medical removal protection benefits to a removed employee shall be reduced to the extent that the employee receives compensation for earnings lost during the period of removal either from a publicly or employer-funded compensation program, or receives income from employment with any employer made possible by virtue of the employee's removal. 6. Employees who do not recover within the 6 months of removal. The employer shall take the following measures with respect to any employee removed from exposure to MDA: a. The employer shall make available to the employee a medical examination pursuant to this section to obtain a final medical determination with respect to the employee; b. The employer shall assure that the final medical determination obtained indicates whether or not the employee may be returned to his or her former job status, and, if not, what steps should be taken to protect the employee's health; c. Where the final medical determination has not yet been obtained, or once obtained indicates that the employee may not yet be returned to his or her former job status the employer shall continue to provide medical removal protection benefits to the employee until either the employee is returned to former job status, or a final medical determination is made that the employee is incapable of ever safely returning to his or her former job status; and d. Where the employer acts pursuant to a final medical determination which permits the return of the employee to his or her former job status despite what would otherwise be an unacceptable liver function test, later questions concerning removing the employee again shall be decided by a final medical determination. The employer need not automatically remove such an employee pursuant to the MDA removal criteria provided by this section. (F) Voluntary removal or restriction of an employee. Where an employer, although not required by this section to do so, removes an employee from exposure to MDA or otherwise places limitations on an employee due to the effects of MDA exposure on the employee's medical condition, the employer shall provide medical removal protection benefits to the employee equal to that required by subsection (n)(9)(E). (o) Recordkeeping. (1) Objective data for exempted operations.

This article applies to all open excavations made in the earth's surface. Excavations are defined to include trenches. (b) Definitions applicable to this article. Accepted engineering practices means those requirements which are compatible with standards of practice required by a registered professional engineer. Aluminum hydraulic shoring. A pre-engineered shoring system comprised of aluminum hydraulic cylinders (crossbraces) used in conjunction with vertical rails (uprights) or horizontal rails (walers). Such system is designed specifically to support the sidewalls of an excavation and prevent cave-ins. Bell-bottom pier hole. A type of shaft or footing excavation, the bottom of which is made larger than the cross section above to form a belled shape. Benching (Benching system). A method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surfaces between levels. Cave-in. The separation of a mass of soil or rock material from the side of an excavation, or the loss of soil from under a trench shield or support system, and its sudden movement into the excavation, either by falling or sliding, in sufficient quantity so that it could entrap, bury, or otherwise injure and immobilize a peron. Crossbraces. The horizontal members of a shoring system installed perpendicular to the sides of the excavation, the ends of which bear against either uprights or wales. Excavation. Any man-made cut, cavity, trench, or depression in an earth surface, formed by earth removal. Faces or sides. The vertical or inclined earth surfaces formed as a result of excavation work. Failure. The breakage, displacement, or permanent deformation of a structural member or connection so as to reduce its structural integrity and its supportive capabilities. Hazardous atmosphere. An atmosphere which by reason of being explosive, flammable, poisonous, corrosive, oxidizing, irritating, oxygen deficient, toxic, or otherwise harmful, may cause death, illness, or injury. Kickout. The accidental release or failure of a cross brace. Protective system. A method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection. Ramp. An inclined walking or working surface that is used to gain access to one point from another, and is constructed from earth or from structural materials such as steel or wood. Registered professional engineer. A person who is registered as a professional engineer in the state where the work is to be performed. However, a professional engineer, registered in any state is deemed to be a "registered professional engineer" within the meaning of this standard when approving designs for "manufactured protective systems" or "tabulated data" to be used in interstate commerce. Sheeting. The members of a shoring system that retain the earth in position and in turn are supported by other members of the shoring system. Shield (Shield system). A structure that is able to withstand the forces imposed on it by a cave-in and thereby protect employees within the structure. Shields can be permanent structures or can be designed to be portable and moved along as work progresses. Additionally, shields can be either premanufactured or job-built in accordance with Section 1541.1(c)(3) or (c)(4). Shields used in trenches are usually referred to as "trench boxes" or "trench shields." Shoring (Shoring system). A structure such as a metal hydraulic, mechanical or timber shoring system that supports the sides of an excavation and which is designed to prevent cave-ins. Sides. See "Faces." Sloping (Sloping system). A method of protecting employees from cave-ins by excavating to form sides of an excavation that are inclined away form the excavation so as to prevent cave-ins. The angle of incline required to prevent a cave-in varies with differences in such factors as the soil type, environmental conditions of exposure, and application of surcharge loads. Stable rock. Natural solid mineral material that can be excavated with vertical sides and will remain intact while exposed. Unstable rock is considered to be stable when the rock material on the side or sides of the excavation is secured against caving-in or movement by rock bolts or by another protective system that has been designed by a registered professional engineer. Structural ramp. A ramp built of steel or wood, usually used for vehicle access. Ramps made of soil or rock are not considered structural ramps. Support system. A structure such as underpinning, bracing, or shoring, which provides support to an adjacent structure, underground installation, or the sides of an excavation. Tabulated data. Tables and charts approved by a registered professional engineer and used to design and construct a protective system. Trench (Trench excavation). A narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth is greater than the width, but the width of a trench (measured at the bottom) is not greater than 15 feet. If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet or less, (measured at the bottom of the excavation), the excavation is also considered to be a trench. Trench box. See "Shield." Trench shield. See "Shield." Uprights. The vertical members of a trench shoring system placed in contact with the earth and usually positioned so that individual members do not contact each other. Uprights placed so that individual members are closely spaced, in contact with or interconnected to each other, are often called "sheeting." Wales. Horizontal members of a shoring system placed parallel to the excavation face whose sides bear against the vertical members of the shoring system or earth.

Such protection shall consist of scaling to remove loose material; installation of protective barricades at intervals as necessary on the face to stop and contain falling material; or other means that provide equivalent protection. (2) Employees shall be protected from excavated or other materials or equipment that could pose a hazard by falling or rolling into excavations. Protection shall be provided by placing and keeping such materials or equipment at least 2 feet from the edge of excavations, or by the use of retaining devices that are sufficient to prevent materials or equipment from falling or rolling into excavations, or by a combination of both if necessary. (k) Inspection. (1) Daily inspections of excavations, the adjacent areas, and protective systems shall be made by a competent person for evidence of a situation that could result in possible cave-ins, indications of failure of protective systems, hazardous atmospheres, or other hazardous conditions. An inspection shall be conducted by the competent person prior to the start of work and as needed throughout the shift. Inspections shall also be made after every rain storm or other hazard increasing occurrence. These inspections are only required when employee exposure can be reasonably anticipated. (2) Where the competent person finds evidence of a situation that could result in a possible cave-in, indications of failure of protective systems, hazardous atmospheres, or other hazardous conditions, exposed employees shall be removed from the hazardous area until the necessary precautions have been taken to ensure their safety. (l) Fall protection. (1) Where employees or equipment are required or permitted to cross over excavations over 6-feet in depth and wider than 30 inches, walkways or bridges with standard guardrails shall be provided. (2) Adequate barrier physical protection shall be provided at all remotely located excavations. All wells, pits, shafts, etc., shall be barricaded or covered.

This appendix describes a method of classifying soil and rock deposits based on site and environmental conditions, and on the structure and composition of the earth deposits. The appendix contains definitions, sets forth requirements, and describes acceptable visual and manual tests for use in classifying soils. (2) Application. This appendix applies when a sloping or benching system is designed in accordance with the requirements set forth in Section 1541.1(b)(2) as a method of protection for employees from cave-ins. This appendix also applies when timber shoring for excavations is designed as a method of protection from cave-ins in accordance with Appendix C to this article, and when aluminum hydraulic shoring is designed in accordance with Appendix D. This appendix also applies if other protective systems are designed and selected for use from data prepared in accordance with the requirements set forth in Section 1541.1(c), and the use of the data is predicated on the use of the soil classification system set forth in this appendix. (b) Definitions. Cemented soil. A soil in which the particles are held together by a chemical agent, such a calcium carbonate, such that a hand-size sample cannot be crushed into powder or individual soil particles by finger pressure. Cohesive soil. Clay (fine grained soil), or soil with a high clay content, which has cohesive strength. Cohesive soil does not crumble, can be excavated with vertical side slopes, and is plastic when moist. Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged. Cohesive soils include clayey silt, sandy clay, silty clay, clay and organic clay. Dry soil. Soil that does not exhibit visible signs of moisture content. Fissured. A soil material that has a tendency to break along definite planes of fracture with little resistance, or a material that exhibits open cracks, such as tension cracks, in an exposed surface. Granular soil. Gravel, sand, or silt (coarse grained soil) with little or no clay content. Granular soil has no cohesive strength. Some moist granular soils exhibit apparent cohesion. Granular soil cannot be molded when moist and crumbles easily when dry. Layered system. Two or more distinctly different soil or rock types arranged in layers. Micaceous seams or weakened planes in rock or shale are considered layered. Moist soil. A condition in which a soil looks and feels damp. Moist cohesive soil can easily be shaped into a ball and rolled into small diameter threads before crumbling. Moist granular soil that contains some cohesive material will exhibit signs of cohesion between particles. Plastic. A property of a soil which allows the soil to be deformed or molded without cracking, or appreciable volume change. Saturated soil. A soil in which the voids are filled with water. Saturation does not require flow. Saturation, or near saturation, is necessary for the proper use of instruments such as a pocket penetrometer or sheer vane. Soil classification system. A method of categorizing soil and rock deposits in a hierarchy of Stable Rock, Type A, Type B, and Type C, in decreasing order of stability. The categories are determined based on an analysis of the properties and performance characteristics of the deposits and the characteristics of the deposits and the environmental conditions of exposure. Stable rock. Natural solid mineral matter that can be excavated with vertical sides and remain intact while exposed. Submerged soil. Soil which is underwater or is free seeping. Type A soil. Cohesive soils with an unconfined, compressive strength of 1.5 ton per square foot (tsf) or greater. Examples of cohesive soils are: clay, silty clay, sandy clay, clay loam and, in some cases, silty clay loam and sandy clay loam. Cemented soils such as caliche and hardpan are also considered Type A. However, no soil is Type A if: (1) The soil is fissured; or (2) The soil is subject to vibration from heavy traffic, pile driving, or similar effects; or (3) The soil has been previously disturbed; or (4) The soil is part of a sloped, layered system where the layers dip into the excavation on a slope of four horizontal to one vertical (4H:1V) or greater; or (5) The material is subject to other factors that would require it to be classified as a less stable material. Type B soil: (1) Cohesive soil with an unconfined compressive strength greater than 0.5 tsf but less than 1.5 tsf; or (2) Granular cohesionless soils including: angular gravel (similar to crushed rock), silt, silt loam, sandy loam and, in some cases, silty clay loam and sandy clay loam. (3) Previously disturbed soils except those which would otherwise be classed as Type C soil. (4) Soil that meets the unconfined compressive strength or cementation requirements for Type A, but is fissured or subject to vibration; or (5) Dry rock that is not stable; or (6) Material that is part of a sloped, layered system where the layers dip into the excavation on a slope less steep than four horizontal to one vertical (4H:1V), but only if the material would otherwise be classified as Type B. Type C soil: (1) Cohesive soil with an unconfined compressive strength of 0.5 tsf or less; or (2) Granular soils including gravel, sand, and loamy sand; or (3) Submerged soil or soil from which water is freely seeping; or (4) Submerged rock that is not stable, or (5) Material in a sloped, layered system where the layers dip into the excavation or a slope of four horizontal to one vertical (4H:1V) or steeper. Unconfined compressive strength. The load per unit area at which a soil will fail in compression. It can be determined by laboratory testing, or estimated in the field using a pocket penetrometer, by thumb penetration tests, and other methods. Wet soil. Soil that contains significantly more moisture than moist soil, but in such a range of values that cohesive material will slump or begin to flow when vibrated. Granular material that would exhibit cohesive properties when moist will lose those cohesive properties when wet. (c) Requirements. (1) Classification of soil and rock deposits. Each soil and rock deposit shall be classified by a competent person as Stable Rock, Type A, Type B, or Type C in accordance with the definitions set forth in paragraph (b) of this appendix. (2) Basis of classification. The classification of the deposits shall be made based on the results of at least one visual and at least one manual analysis. Such analyses shall be conducted by a competent person using tests described in paragraph (d) below, or in other approved methods of soil classification and testing such as those adopted by the American Society for Testing Materials, or the U.S. Department of Agriculture textural classification system. (3) Visual and manual analyses. The visual and manual analyses, such as those noted as being acceptable in paragraph (d) of this appendix, shall be designed and conducted to provide sufficient quantitative and qualitative information as may be necessary to identify properly the properties, factors, and conditions affecting the classification of the deposits. (4) Layered systems. In a layered system, the system shall be classified in accordance with its weakest layer. However, each layer may be classified individually where a more stable layer lies under a less stable layer. (5) Reclassification. If, after classifying a deposit, the properties, factors, or conditions affecting its classification change in any way, the changes shall be evaluated by a competent person. The deposit shall be reclassified as necessary to reflect the changed circumstances. (d) Acceptable visual and manual tests. (1) Visual tests. Visual analysis is conducted to determine qualitative information regarding the excavation site in general, the soil adjacent to the excavation, the soil forming the sides of the open excavation, and the soil taken as samples from excavated material. (A) Observe samples of soil that are excavated and soil in the sides of the excavation. Estimate the range of particle sizes and the relative amounts of the particle sizes. Soil that is primarily composed of fine-grained material is cohesive material. Soil composed primarily of coarse-grained sand or gravel is granular material. (B) Observe soil as it is excavated. Soil that remains in clumps when excavated is cohesive. Soil that breads up easily and does not stay in clumps is granular. (C) Observe the side of the opened excavation and the surface area adjacent to the excavation. Crack-like openings such as tension cracks could indicate fissured material. If chunks of soil spall off a vertical side, the soil could be fissured. Small spalls are evidence of moving ground and are indications of potentially hazardous situations. (D) Observe the area adjacent to the excavation and the excavation itself for evidence of existing utility and other underground structures, and to identify previously disturbed soil. (E) Observe the opened side of the excavation to identify layered systems. Examine layered systems to identify if the layers slope toward the excavation. Estimate the degree of slope of the layers. (F) Observe the area adjacent to the excavation and the sides of the opened excavation for evidence of surface water, water seeping from the sides of the excavation, or the location of the level of the water table. (G) Observe the area adjacent to the excavation and the area within the excavation for sources of vibration that may affect the stability of the excavation face. (2) Manual tests. Manual analysis of soil samples in conducted to determine quantitative as well as qualitative properties of soil and to provide more information in order to classify soil properly. (A) Plasticity. Mold a moist or wet sample of soil into a ball and attempt to roll it into threads as thin as 1/8-inch in diameter. Cohesive material can be successfully rolled into threads without crumbling. For example, if at least a two inch length of 1/8-inch thread can be held on one end without tearing, the soil is cohesive. (B) Dry strength. If the soil is dry and crumbles on its own or with moderate pressure into individual grains or fine powder, it is granular (any combination of gravel, sand, or silt). If the soil is dry and falls into clumps which break up into smaller clumps, but the smaller clumps can only be broken up with difficulty, it may be clay in any combination with gravel, sand or silt. If the dry soil breads into clumps which do not break up into small clumps and which can only be broken with difficulty, and there is no visual indication the soil is fissured, the soil may be considered unfissured. (C) Thumb penetration. The thumb penetration test can be used to estimate the unconfined compressive strength of cohesive soils. Type A soils with an unconfined compressive strength of 1.5 tsf can be readily indented by the thumb; however, they can be penetrated by the thumb only with very great effort. Type C soils with an unconfined compressive strength of 0.5 tsf can be easily penetrated several inches by the thumb, and can be molded by light finger pressure. This test should be conducted on an undisturbed soil sample, such as a large clump of spoil, as soon as practicable after excavation to keep to a minimum the effects of exposure to drying influences (rain, flooding), the classification of the soil must be changed accordingly. (D) Other strength tests. Estimates of unconfined compressive strength of soils can also be obtained by use of a pocket penetrometer or by using a hand-operated shearvane. (E) Drying test. The basic purpose of the drying test is to differentiate between cohesive material with fissures, unfissured cohesive material, and granular material. The procedure for the drying test involves drying a sample of soil that is approximately one inch thick and six inches in diameter until it is thoroughly dry: 1. If the sample develops cracks as it dries, significant fissures are indicated. 2. Samples that dry without cracking are to be broken by hand. If considerable force is necessary to bread a sample, the soil has significant cohesive material content. The soil can be classified as an unfissured cohesive material and the unconfined compressive strength should be determined. 3. If a sample breaks easily by hand, it is either a fissured cohesive material or a granular material. To distinguish between the two, pulverize the dried clumps of the sample by hand or by stepping on them. If the clumps do not pulverize easily, the material is cohesive with fissures. If they pulverize easily into very small fragments, the material is granular. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. Appendix B Sloping and Benching (a) Scope and application. This appendix contains specifications for sloping and benching when used as methods of protecting employees working in excavations from cave-ins. The requirements of this appendix apply when the design of sloping and benching protective systems is to be performed in accordance with the requirements set forth in Section 1541.1(b). (b) Definitions. Actual slope means the slope to which an excavation face is excavated. Distress means that the soil is in a condition where a cave-in is imminent or is likely to occur. Distress is evidenced by such phenomena as the development of fissures in the face of or adjacent to an open excavation; the subsidence of the edge of an excavation; the slumping of material from the face or the bulging or heaving of material from the bottom of an excavation; the spalling of material from the face of an excavation; and ravelling, i.e., small amounts of material such as pebbles or little clumps of material suddenly separating from the face of an excavation and trickling or rolling down into the excavation. Maximum allowable slope means the steepest incline of an excavation face that is acceptable for the most favorable site conditions as protection against cave-ins, and is expressed as the ratio of horizontal distance to vertical rise (H:V), Short term exposure means a period of time less than or equal to 24 hours that an excavation is open. (c) Requirements. (1) Soil classification. Soil and rock deposits shall be classified in accordance with Appendix A to Section 1541.1. (2) Maximum allowable slope. The maximum allowable slope for a soil or rock deposit shall be determined from Table B-1 of this appendix. (3) Actual slope. (A) The actual slope shall not be steeper than the maximum allowable slope. (B) The actual slope shall be less steep than the maximum allowable slope, when there are signs of distress. If that situation occurs, the slope shall be cut back to an actual slope which is at least 1/2 horizontal to one vertical (1/2H:1V) less steep than the maximum allowable slope. (C) When surcharge loads from stored material or equipment, operating equipment, or traffic are present, a competent person shall determine the degree to which the actual slope must be reduced below the maximum allowable slope, and shall assure that such reduction is achieved. Surcharge loads from adjacent structures shall be evaluated in accordance with Section 1541(i). (4) Configurations. Configurations of sloping and benching systems shall be in accordance with Figure B-1. TABLE B-1 MAXIMUM ALLOWABLE SLOPES NOTES: 1. Numbers shown in parentheses next to maximum allowable slopes are angles expressed in degrees from the horizontal. Angles have been rounded off. 2. A short-term maximum allowable slope of 1/2H:1V (63 degrees) is allowed in excavations in Type A soil that are 12 feet or less in depth. Short-term maximum allowable slopes for excavations greater than 12 feet in depth shall be 3/4H:1V (53 degrees). 3.

Appendix C Timber Shoring for Trenches (a) Scope. This appendix contains information that can be used when timber shoring is provided as a method of protection from cave-ins in trenches that do not exceed 20 feet in depth. This appendix must be used when design of timber shoring protective systems is to be performed in accordance with Section 1541.1(c)(1). Other timber shoring configurations; other systems of support such as hydraulic and pneumatic systems; and other protective systems such as sloping, benching, shielding, and freezing systems must be designed in accordance with the requirements set forth in Section 1541.1(b) and 1541.1(c). (b) Soil Classification. In order to use the data presented in this appendix, the soil type or types in which the excavation is made must first be determined using the soil classification method set forth in Article 6. (c) Presentation of Information. Information is presented in several forms as follows: (1) Information is presented in tabular form in Tables C-1.1, C-1.2 and C-1.3, and Tables C-2.1, C-2.2 and C-2.3 following Section (g) of Appendix C. Each table presents the minimum sizes of timber members to use in a shoring system, and each table contains data only for the particular soil type in which the excavation or portion of the excavation is made. The data are arranged to allow the user the flexibility to select from among several acceptable configurations of members based on varying the horizontal spacing of the crossbraces. Stable rock is exempt from shoring requirements and therefore, no data are presented for this condition. (2) Information concerning the basis of the tabular data and the limitations of the data is presented in Section (d) of this appendix, and on the tables themselves. (3) Information explaining the use of the tabular data is presented in Section (e) of this appendix. (4) Information illustrating the use of the tabular data is presented in Section (f) of this appendix. (5) Miscellaneous notations regarding Tables C-1.1 through C-1.3 and Tables C-2.1 through C-2.3 are presented in Section (g) of this appendix. (d) Basis and limitations of the data. (1) Dimensions of timber members. (A) The sizes of the timber members listed in Tables C-1.1 through C-1.3 are taken from the National Bureau of Standards (NBS) report, "Recommended Technical Provisions for Construction Practice in Shoring and Sloping of Trenches and Excavations." In addition, where NBS did not recommend specific sizes of members, member sizes are based on an analysis of the sizes required for use by existing codes and on empirical practice. (B) The required dimensions of the members listed in Tables C-1.1 through C-1.3 refer to actual dimensions and not nominal dimensions of the timber. Employers wanting to use nominal size shoring are directed to Tables C-2.1 through C-2.3, or have this choice under Section 1541.1(c)(3). (2) Limitation of application. (A) It is not intended that the timber shoring specification apply to every situation that may be experienced in the field. These data were developed to apply to the situations that are most commonly experienced in current trenching practice. Shoring systems for use in situations that are not covered by the data in this appendix must be designed as specified in Section 1541.1(c). (B) When any of the following conditions are present, the members specified in the tables are not considered adequate. Either an alternate timber shoring system must be designed or another type of protective system designed in accordance with Section 1541.1. 1. When loads imposed by structures or by stored material adjacent to the trench weigh in excess of the load imposed by a two-foot soil surcharge. The term "adjacent" as used here means the area within a horizontal distance from the edge of the trench equal to the depth of the trench. 2. When vertical loads imposed on crossbraces exceed a 240-pound gravity load distributed on a one-foot section of the center of the crossbrace. 3. When surcharge loads are present from equipment weighing in excess of 20,000 pounds. 4. When only the lower portion of a trench is shored and the remaining portion of the trench is sloped or benched unless: The sloped portion is sloped at an angle less steep than three horizontal to one vertical; or the members are selected from the tables for use at a depth which is determined from the top of the overall trench, and not from the toe of the sloped portion. (e) Use of Tables. The members of the shoring system that are to be selected using this information are the crossbraces, the uprights, and the wales, where wales are required. Minimum sizes of members are specified for use in different types of soil. There are six tables of information, two for each soil type. The soil type must first be determined in accordance with the soil classification system described in Appendix A. Using the appropriate table, the selection of the size and spacing of the members is then made. The selection is based on the depth and width of the trench where the members are to be installed and, in most instances, the selection is also based on the horizontal spacing of the crossbraces. Instances where a choice of horizontal spacing of crossbracing is available, the horizontal spacing of the crossbraces must be chosen by the user before the size of any member can be determined. When the soil type, the width and depth of the trench, and the horizontal spacing of the crossbraces, the size and vertical spacing of the crossbraces are known, the size and vertical spacing of the crossbraces, the size and vertical spacing of the wales, and the size and horizontal spacing of the uprights can be read from the appropriate table. (f) Examples to Illustrate the Use of Tables C-1.1 through C-1.3. (1) Example 1. A trench dug in Type A soil is 13 feet deep and five feet wide. From Table C-1.1, four acceptable arrangements of timber can be used. Arrangement #1 Space 4X4 crossbraces at six feet horizontally and four feet vertically. Wales are not required. Space 3X8 uprights at six feet horizontally. This arrangement is commonly called "skip shoring." Arrangement #2 Space 4X6 crossbraces at eight feet horizontally and four feet vertically. Space 8X8 wales at four feet vertically. Space 2X6 uprights at four feet horizontally. Arrangement #3 Space 6X6 crossbraces at 10 feet horizontally and four feet vertically. Space 8X10 wales at four feet vertically. Space 2X6 uprights at five feet horizontally. Arrangement #4 Space 6X6 crossbraces at 12 feet horizontally and four feet vertically. Space 10X10 wales at four feet vertically. Space 3X8 uprights at six feet horizontally. (2) Example 2. A trench dug in Type B soil is 13 feet deep and five feet wide. From Table C-1.2 three acceptable arrangements of members are listed. Arrangement #1 Space 6X6 crossbraces at six feet horizontally and five feet vertically. Space 8X8 wales at five feet vertically. Space 2X6 uprights at two feet horizontally. Arrangement #2 Space 6X8 crossbraces at eight feet horizontally and five feet vertically. Space 10X10 wales at five feet vertically. Space 2X6 uprights at two feet horizontally. Arrangement #3 Space 8X8 crossbraces at 10 feet horizontally and five feet vertically. Space 10X12 wales at five feet vertically. Space 2X6 uprights at two feet vertically. (3) Example 3. A trench dug in Type C soil is 13 feet deep and five feet wide. From Table C-1.3 two acceptable arrangements of members can be used. Arrangement #1 Space 8X8 crossbraces at six feet horizontally and five feet vertically. Space 10X12 wales at five feet vertically. Position 2X6 uprights as closely together as possible. If water must be retained use special tongue and groove uprights to form tight sheeting. Arrangement #2 Space 8X10 crossbraces at eight feet horizontally and five feet vertically. Space 12X12 wales at five feet vertically. Position 2X6 uprights in a close sheeting configuration unless water pressure must be resisted. Tight sheeting must be used where water must be retained. (4) Example 4. A trench dug in Type C soil is 20 feet deep and 11 feet wide. The size and spacing of members for the section of trench that is over 15 feet in depth is determined using Table C-1.3. Only one arrangement of members is provided. Space 8X10 crossbraces at six feet horizontally and five feet vertically. Space 12X12 wales at five feet vertically. Use 3X6 tightsheeting. Use of Tables C-2.1 through C-2.3 would follow the same procedures. (g) Notes for all Tables. 1. Members sizes at spacings other than indicated are to be determined as specified in Section 1541.1(c), "Design of Protective Systems." 2. When conditions are saturated or submerged use Tight Sheeting. Tight Sheeting refers to the use of specially-edged timber planks (e.g., tongue and groove) at least three inches thick, steel sheet piling, or similar construction that when driven or placed in position provide a tight wall to resist the lateral pressure of water and to prevent the loss of backfill material. Close Sheeting refers to the placement of planks side-by-side allowing as little space as possible between them. 3. All spacing indicated is measured center to center. 4.. Wales to be installed with greater dimension horizontal. 5. If the vertical distance from the center of the lowest crossbrace to the bottom of the trench exceeds two and one-half feet, uprights shall be firmly embedded or a mudsill shall be used. Where uprights are embedded, the vertical distance from the center of the lowest crossbrace to the bottom of the trench shall not exceed 36 inches. When mudsills are used, the vertical distance shall not exceed 42 inches. Mudsills are wales that are installed at the toe of the trench side. 6. Trench jacks may be used in lieu of or in combination with timber crossbraces. 7. Placement of crossbraces. When the vertical spacing of crossbraces is four feet, place the top crossbrace no more than two feet below the top of the trench. When the vertical spacing of crossbraces is five feet, place the top crossbrace no more than 2.5 feet below the top of the trench.

This appendix contains information that can be used when aluminum hydraulic shoring is provided as a method of protection against cave-ins in trenches that do not exceed 20 feet in depth. This appendix must be used when design of the aluminum hydraulic protective system cannot be performed in accordance with Section 1541.1(c)(2). (b) Soil Classification. In order to use data presented in this appendix, the soil type or types in which the excavation is made must first be determined using the soil classification method set forth in Appendix A of this Article. (c) Presentation of Information. Information is presented in several forms as follows: (1) Information is presented in tabular form in Tables D-1.1, D-1.2, D-1.3 and D-1.4. Each table presents the maximum vertical and horizontal spacings that may be used with various aluminum member sizes and various hydraulic cylinder sizes. Each table contains data only for the particular soil type in which the excavation or portion of the excavation is made. Tables D-1.1 and D-1.2 are for vertical shores in Types A and B soil. Tables D-1.3 and D-1.4 are for horizontal waler systems in Types B and C soil. (2) Information concerning the basis of the tabular data and the limitations of the data is presented in Section (d) of this appendix. (3) Information explaining the use of the tabular data is presented in Section (e) of this appendix. (4) Information illustrating the use of the tabular data is presented in Section (f) of this appendix. (5) Miscellaneous notations (footnotes) regarding Table D-1.1 through D-1.4 are presented in Section (g) of this appendix. (6) Figures, illustrating typical installations of hydraulic shoring, are included just prior to the Tables. The illustrations page is entitled "Aluminum Hydraulic Shoring: Typical Installations." (d) Basis and limitations of the data. (1) Vertical shore rails and horizontal wales are those that meet the Section Modulus requirements in the D-1 Tables. Aluminum material is 6061-T6 or material of equivalent strength and properties. (2) Hydraulic cylinders specifications. (A) 2-inch cylinders shall be a minimum 2-inch inside diameter with a minimum safe working capacity of no less than 18,000 pounds axial compressive load at maximum extension. Maximum extension is to include full range of cylinder extensions as recommended by product manufacturer. (B) 3-inch cylinders shall be minimum 3-inch inside diameter with a safe working capacity of not less than 30,000 pounds axial compressive load at extensions as recommended by product manufacturer. (3) Limitation of application. (A) It is not intended that the aluminum hydraulic specification apply to every situation that may be experienced in the field. These data were developed to apply to the situations that are most commonly experienced in current trenching practice. Shoring systems for use in situations that are not covered by the data in this appendix must be otherwise designed as specified in Section 1541.1(c). (B) When any of the following conditions are present, the members specified in the Tables are no considered adequate. In this case, an alternative aluminum hydraulic shoring system or other type of protective system must be designed in accordance with Section 1541.1. 1. When vertical loads imposed on crossbraces exceed a 100 pound gravity load distributed on a one foot section of the center of the hydraulic cylinder. 2. When surcharge loads are present from equipment weighing in excess of 20,000 pounds. 3. When only the lower portion of a trench is shored and the remaining portion of the trench is sloped or benched unless: The sloped portion is sloped at an angle less steep than three horizontal to one vertical; or the members are selected from the tables for use at a depth which is determined from the top of the overall trench, and not from the toe of the sloped portion. (e) Use of Tables D-1.1, D-1.2, D-1.3 and D-1.4. The members of the shoring system that are to be selected using this information are the hydraulic cylinders, and either the vertical shores or the horizontal wales. When a waler system is used the vertical timber sheeting to be used is also selected from these tables. The Tables D-1.1 and D-1.2 for vertical shores are used in Type A and B soils that do not require sheeting. Type B soils that may require sheeting, and Type C soils that always require sheeting, are found in the horizontal wale Tables D-1.3 and D-1.4. The soil type must first be determined in accordance with the soil classification system described in Appendix A to Section 1541.1. Using the appropriate table, the selection of the size and spacing of the members is made. The selection is based on the depth and width of the trench where the members are to be installed. In these tables the vertical spacing is held constant at four feet on center. The tables show the maximum horizontal spacing of cylinders allowed for each size of wale in the waler system tables, and in the vertical shore tables, the hydraulic cylinder horizontal spacing is the same as the vertical shore spacing. (f) Example to Illustrate the Use of the Tables: (1) Example 1. A trench dug in Type A soil is 6 feet deep and 3 feet wide. From Table D-1.1: Find vertical shores and 2 inch diameter cylinders spaced 8 feet on center (o.c.) horizontally and 4 feet on center (o.c.) vertically. (See Figures 1 & 3 for typical installations.) (2) Example 2: A trench is dug in Type B soil that does not require sheeting, 13 feet deep and 5 feet wide. From Table D-1.2: Find vertical shores and 2 inch diameter cylinders spaced 6.5 feet o.c. horizontally and 4 feet o.c. vertically. (See Figures 1 & 3 for typical installations.) (3) Example 3: A trench is dug in Type B soil that does not require sheeting, but does experience some minor raveling of the trench face. The trench is 16 feet deep and 9 feet wide. From Table D-1.2: Find vertical shores and 2 inch diameter cylinder (with special oversleeves as designated by footnote #2) spaced 5.5 feet o.c. horizontally and 4 feet o.c. vertically. Plywood (per footnote (g)(7) to the D-1 Table) should be used behind the shores. (See Figures 2 & 3 for typical installations.) (4) Example 4: A trench is dug in previously disturbed Type B soil, with characteristics of a Type C soil, and will require sheeting. The trench is 18 feet deep, and 12 feet wide. 8 foot horizontal spacing between cylinders is desired for working space. From Table D-1.3: Find horizontal wale with a section modulus of 14.0 spaced at 4 feet o.c. vertically and 3 inch diameter cylinder spaced at 9 feet maximum o.c. horizontally, 3 x 12 timber sheeting is required at close spacing vertically. (See Figure 4 for typical installation.) (5) Example 5: A trench is dug in Type C soil, 9 feet deep and 4 feet wide. Horizontal cylinder spacing in excess of 6 feet is desired for working space. From Table D-1.4: Find horizontal wale with a section modulus of 7.0 and 2 inch diameter cylinders spaced at 6.5 feet o.c. horizontally. Or, find horizontal wale with a 14.0 section modulus and 3 inch diameter cylinder spaced at 10 feet o.c. horizontally. Both wales are spaced 4 feet o.c. vertically, 3x12 timber sheeting is required at close spacing vertically. (See Figure 4 for typical installation.) (g) Footnotes, and general notes, for Tables D-1.1, D-1.2, D-1.3, and D-1.4. (1) For applications other than those listed in the tables, refer to Section 1541.1(c)(2) for use of manufacturer's tabulated data. For trench depths in excess of 20 feet, refer to Section 1541.1(c)(2) and 1541.1(c)(3). (2) 2-inch diameter cylinders, at this width, shall have structural steel tube (3.5 x 3.5 x 0.1875) oversleeves, or structural oversleeves of manufacturer's specification, extending the full, collapsed length. (3) Hydraulic cylinders capacities. (A) 2-inch cylinders shall be a minimum 2-inch inside diameter with a safe working capacity of not less than 18,000 pounds axial compressive load at maximum extension. Maximum extension is to include full range of cylinder extensions as recommended by product manufacturer. (B) 3-inch cylinders shall be a minimum 3-inch inside diameter with a safe work capacity of not less than 30,000 pounds axial compressive load at maximum extension. Maximum extension is to include full range of cylinder extensions as recommended by product manufacturer. (4) All spacing indicated is measured center to center. (5) Vertical shoring rails shall have a minimum section modulus of 0.40 inch. (6) When vertical shores are used, there must be a minimum of three shores spaced equally, horizontally, in a group. (7) Plywood shall be 1.125 inches thick of wood or 0.75 inch thick, 14 ply, arctic white birch (Finland form). Please note that plywood is not intended as a structural member, but only for prevention of local raveling (sloughing of the trench face) between shores. Equivalent material may be used if it has been approved in accordance with Section 1505(a). (8) See Appendix C for timber specifications. (9) Wales are calculated for simple span conditions. (10) See Appendix D, Section (d), for basis and limitations of the data. Appendix E to Section 1541.1 Alternatives to Timber Shoring Note: Authority Cited: Section 142.3, Labor Code.

These are safeties which develop a rapidly increasing pressure on the guide members during the stopping interval, the stopping distance being very short due to the inherent design of the safety. The operating force is derived entirely from the mass and the motion of the car or the counterweight being stopped. These safeties apply pressure on the guide or tension members through eccentrics, rollers, or similar devices without any flexible medium purposely introduced to limit the retarding force and increase the stopping distance. (2) Type B Safeties. These are safeties which apply limited pressure on the guide or tension members during the stopping interval and which provide stopping distances that are related to the mass being stopped and the speed at which application of the safety is initiated. Retarding forces are reasonably uniform after the safety is fully applied. Continuous tension in the governor rope may or may not be required to operate the safety during the entire stopping interval. Minimum and maximum distances are specified on the basis of governor-tripping speed. (3) Type C Safeties (Type A With Oil Buffers). These are safeties which develop retarding forces during the compression stroke of one or more oil buffers interposed between the lower members of the car frame and a governor operated Type A auxiliary safety plank applied on the guide or tension members. The stopping distance is equal to the effective stroke of the buffers. (4) Rack and Pinion Safeties. These are safeties in which a freely rotating safety pinion, a governor, and a safety device may form an integral unit mounted on the car. The freely rotating pinion travels on a stationary rack mounted vertically on the hoist structure. The rotating pinion drives the governor. When the downward speed of the car reaches the tripping value, the rotating governor actuates the safety device, which, in turn, brings the car to a gradual stop.

The ribbons shall be long enough to extend from upright to upright without splices. Exceptions: 1. When metal ledgers are used or when ledgers are bolted or when a 45-degree angle brace is nailed to the uprights between double ledgers, and ledgers also nailed to this brace, the ribbon may be placed at other elevations such as guardrail height, but they cannot be eliminated from the scaffold. 2. Metal ledgers and ribbons that are part of a patented scaffold system may be used when installed in accordance with the manufacturer's instructions. (3) Ties and Braces. The scaffold shall be securely tied to the building or structure by means of a double looped No. 12 iron wire, or single looped No. 10 iron wire or 1-inch by 4-inch boards with at least 2 nails at each connection or equivalent means. Ties shall connect to the inside uprights and shall not be more than 20 feet apart horizontally and vertically. The outside line of uprights shall contain sufficient diagonal bracing of 1-inch by 6-inch material in a vertical plane across the entire face of the scaffold in both directions to prevent swaying, tipping, or collapsing. (See Appendix Plate B-18). Exception: Bracing of 2-inch by 4-inch material may be used provided that the bracing extends from ledger to next higher or lower ledger or from ledger to sill in the form of an "X" in the end bays and in every third bay in between so that the "X" bracing also extends from the upper-most ledger to the sill, vertically, in each of these bays. (4) Railing. Open sides and ends of intermediate working levels 7 1/2 feet or more above grade shall be guarded by a 2-inch by 4-inch top rail nailed to the uprights so that the top edge is between 42 inches and 45 inches above the platform. Midrails of at least 2-inch by 4-inch material are required at all work levels. The uppermost platform shall be protected by a top rail consisting of double 2-inch by 4-inch members.

The phrase "reinforced sufficiently to ensure its integrity" used in this section means that a civil engineer currently registered in California, independent of the engineer who designed and planned the lifting operation, has determined from the plans that if there is a loss of support at any jack location, that loss will be confined to that location and the structure as a whole will remain stable. (1) Under no circumstances, shall any employee who is not essential to the jacking operation be permitted immediately beneath a slab while it is to be lifted. (2) For the purpose of section 1722.1(k), a jacking operation begins when a slab or group of slabs is lifted and ends when such slabs are secured (with either temporary connections or permanent connections). ( l) When making temporary connections to support slabs, wedges shall be secured by tack welding, or an equivalent method of securing the wedges to prevent them from falling out of position. Lifting rods may not be released until the wedges at that column have been secured. (m) All welding on temporary and permanent connections shall be performed by a certified welder, according to the welding requirements specified in the plans and specifications for the lift-slab operation. (n) Load transfer from jacks/lifting units to building columns shall not be executed until the welds on the column shear plates (weld blocks) are cooled to air temperature. (o) Jacks/lifting units shall be positively secured to building columns so that they do not become dislodged or dislocated. (p) Equipment shall be designed and installed so that the lifting rods cannot slip out of position or the employer shall institute other measures, such as the use of locking or blocking devices, which will provide positive connection between the lifting rods and attachments and will prevent components from disengaging during lifting operations.

(a) Demolition work shall at all times be under the immediate supervision of a qualified person with the authority to secure maximum safety for employees engaged in demolition work. (b)(1) Prior to permitting employees to start demolition operations, a qualified person shall make a survey of the structure to determine the condition of the framing, floors, and walls, and the possibility of an unplanned collapse of any portion of the structure. Any adjacent structure where employees may be exposed shall also be similarly checked. (2) The survey shall be in written form, kept on the job-site and made available to the Division upon request. The written survey shall be maintained for the duration of the demolition project. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1735. Demolishing Buildings. (a) Utility companies shall be notified and all utility service shut off, capped, or otherwise controlled, at the building or curb line before starting demolition, unless it is necessary to use electricity or water lines during demolition. If use is necessary, the utility services shall be relocated or rearranged as necessary and protected from physical damage. (b) It shall also be determined if any type of hazardous chemicals, gases, explosives, flammable materials, or similarly dangerous substances have been used in any pipes, tanks, or other equipment on the property. When the presence of any such substances is apparent or suspected, testing and purging shall be performed and the hazard eliminated before demolition is started. (c) Pipe-covering insulation, steel beam and column fire protection, and heating, ventilating and air-conditioning duct work shall be surveyed for asbestos. If asbestos is present, the employer shall comply with Section 1529. (d)(1) Prior to starting demolition operations, all structural or other hazardous deficiencies noted during the survey required by Section 1734(b)(1) shall be shored, braced or otherwise corrected as recommended in the survey. (2) Walls, which serve as retaining walls to support earth or adjoining structures, shall not be demolished until the hazard from moving ground has been eliminated by sloping, shoring or, where necessary, adjoining structures have been properly underpinned. (3) Walls, which are to serve as retaining walls against which debris will be piled, shall not be so used unless determined to be capable of safely supporting the imposed load. (4) During demolition, continuing inspections shall be made as the work progresses to detect hazards resulting from weakened or deteriorated floors or walls, or loosened material. Employees shall not be permitted to work where such hazards exist until they are corrected by shoring, bracing, or other effective means. (e) In demolishing any building or structure or alteration involving partial demolition thereof, all material displaced, unless required for reconstruction, shall be transported immediately to the ground. The amount of material stored upon any structure or any portion of such structure shall not exceed its safe carrying capacity. (f)(1) Except for the cutting of holes in floors for chutes, holes through which to drop materials, preparation of storage space, and similar necessary preparatory work, the demolition of exterior walls and floor construction shall begin at the top of the structure and proceed downward and each story of exterior wall and floor construction shall be removed and dropped into the storage space before commencing the removal of exterior walls and floors in the story next below. (2) Any openings cut in a floor for the disposal of materials shall be no larger in size than 25 percent of the aggregate of the total floor area, unless the lateral supports of the removed flooring remain in place. Floors weakened or otherwise made unsafe by demolition operations shall be shored to safely support the intended imposed load from demolition operations. (3) Flooring boards may be removed from not more than one floor above grade to provide storage space for debris, provided falling material is not permitted to endanger structural stability. (4) When wood floor beams serve to brace interior walls or free-standing exterior walls, such beams shall be left in place until other equivalent support can be installed to replace them. Note: For selective demolition by explosives of buildings and structures, refer to appropriate Articles of Group 18, Explosives and Pyrotechnics of the General Industry Safety Orders and this Article. (g) Sections of walls shall not be allowed to fall upon floors supported by wood joists or other floors unable to withstand such impact. (h) Walkways that meet the requirements of Section 1624 shall be provided where necessary for access. (i) Walking across exposed floor joists, steel beams, or girders is prohibited. (j) All persons on demolition projects shall be protected from falling material at employee entrances to multi-story structures being demolished, by sidewalk sheds or canopies or both, providing protection extending from the face of the building for a minimum of 8 feet. All such canopies shall be at least two feet wider than the building entrances or openings (one foot wider on each side thereof) and shall be capable of sustaining a load of 150 pounds per square foot. (k) Exterior wall openings on all floors shall be protected to a height of not less than 42 inches, except on the ground floor and the floor being demolished. (l) Where a hazard exists from fragmentation of glass, all glazed openings shall be removed at least one floor below the working level. (m)(1) No wall section, which is more than one story or 12 feet in height, shall be permitted to stand alone without lateral bracing, unless a civil engineer, currently registered in California, has submitted engineering data to the Division substantiating the capability of the wall to stand without lateral support. (2) All walls shall be left in a stable condition at the end of each work day. (n) Steel construction shall be dismantled column length by column length, and tier by tier (columns may be two-story lengths.) Any structural unit being dismantled shall not be overstressed. (o) Planks spanning the distance between adequate beams shall be used where necessary as a substitute for weakened floors, and as access walkways over open or weakened areas. When demolishing floors and roofs, employees shall be prohibited from working below this activity. Demolition of floor spaces shall continue until all unsupported flooring is removed. When employees are required to remove floor support beams, wall sections, etc., by hand, scaffolding as described in Article 21 of the Construction Safety Orders or elevating work platforms and aerial devices as described in Article 24 of the General Industry Safety Orders shall be provided and used where necessary to insure employee safety. (p)(1) Stairways designated as means of access shall be maintained clear for use within two floors or twenty-four feet of the demolition work above. (2) Ladders shall be provided for these remaining two floors and shall be constructed and maintained in accordance with Article 25, Ladders. Other access ways shall be entirely closed off at all times. (3) Walkways or ladders shall be provided to enable employees to safely reach or leave any scaffold or wall. (g) In a multi-story building, when a stairwell is being used for access or egress, it shall be properly illuminated by either natural or artificial means, and completely and substantially covered over at a point not less than two floors below the floor on which work is being performed, and access to the floor where the work is in progress shall be through a properly lighted, protected, and separate passageway.

(2) Landings shall be provided for the passenger elevators on or in buildings at intervals not to exceed four floors or forty-eight feet. (3) Where there is doubt concerning structural integrity or engineering data indicates attachment of an elevator may jeopardize the strength of the building or structure, the Division may permit alternate methods of installation. Other means of employee access may also be allowed by the Division where the above is clearly impractical. (s) If the method of demolition leaves the structural steel frame in place, then the tier of beams next below the tier from which beams and columns are being removed shall be planked over, unless safety nets are used or the floor of such tier has not been removed. Necessary openings for material handling are allowed. All loose material shall be removed from the steel frame as demolition progresses downward. (t) Provisions for dust control shall include the use of water to keep material or debris sufficiently wet or other equivalent steps taken to prevent dust from rising. (u) Mechanical equipment shall not be used on floors or working surfaces unless a qualified person has determined that such floors or surfaces are of sufficient strength to support the imposed load. (v) Where mechanical equipment is used for demolition work, floor openings shall have curbs or stop-logs to prevent equipment from running over the edge. (w) No salvage of materials shall be permitted during demolition operations on any building, structure, falsework or scaffold more than three stories high or the equivalent height for which a permit is required.

(a) Whenever waste material is dropped to any point lying outside the exterior walls of the building, enclosed chutes shall be used unless the area is effectively protected by barricades, fences or equivalent means. Signs shall be posted to warn employees of the hazards of falling debris. (b) When chutes are used to load trucks, they shall be fully enclosed. Gates shall be installed in each chute at or near the discharge end. A qualified person shall be assigned to control the operation of the gate, and the backing and loading of trucks. (c) Enclosed chutes should be designed for free flow of material, but if clogging or stoppages occur, employees shall not remove material from the chutes with their hands. Picks or other suitable implements shall be used for this purpose. (d) Any chute opening, into which employees dump debris by hand, shall be protected by a guardrail. Any open spaces between the chute and the edge of floor openings through which the chute passes shall be covered over. (e) When operations are not in progress, the discharge end of the chute shall be securely closed off, or the area barricaded or fenced as provided in Section 1736(a). (f) When debris is dropped through holes in the floor without the use of chutes, the area onto which the material is dropped shall be completely enclosed with barricades not less than 42 inches high, and not less than six feet back from the projected edge of the opening above. Signs warning of the hazard of falling materials shall be posted at each level. Debris removal shall not be permitted in this lower drop area until debris handling ceases above. (g) All scrap lumber, waste material, and rubbish shall be removed from the immediate work area as the work progresses. (h) All solvent waste, oily rags, and flammable liquids shall be kept in fire resistant covered containers until removed from the work site. (i)(1) Where the material is dumped from mechanical equipment or wheelbarrows, a securely attached toeboard or bumper, not less than six inches thick and six inches high, shall be provided at each chute opening. (2) Chutes shall be designed and constructed of such strength as to eliminate failure due to impact of materials or debris loaded therein. (j) All material chutes, or sections thereof, at an angle of more than 45 degrees from the horizontal, shall be entirely enclosed, except for openings equipped with closures at or about floor level for the insertion of materials. The openings shall not exceed 48 inches in height measured along the wall of the chute. At all stories below the top floor, such openings shall be kept closed when not in use.

Reference: Section 142.3, Labor Code. s 1739. Permit to Operate. s 1740. Storage and Use of Cylinders. (a) All gas cylinders shall be protected against undue absorption of heat. (b) Gas cylinders shall be stored and used with the valve end up. Cylinders containing oxygen, acetylene or fuel-gases shall not be taken into confined spaces. (c) Gas cylinders in portable service shall be conveyed by suitable hand trucks to which they are securely fastened, or safely carried where job conditions require. All gas cylinders in service shall be securely held in substantial fixed or portable racks, or placed so they will not fall or be knocked over. Valve protection caps, when provided for, shall be put in place before cylinders are moved, transported or stored. (d) Gas cylinders raised or lowered by crane, hoist, or derrick must be handled in suitable cradles, nets, or skip boxes, and shall never be lifted by magnet or by rope or chain slings. (e) Cylinders must not be placed where they might form a part of any electric circuit. (f) No attempt shall be made to transfer acetylene from one cylinder to another, or to mix gases in a cylinder. (g) Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease), a minimum distance of 20 feet or by a noncombustible barrier at least 5 feet high having a fire-resistance rating of at least one-half hour. (h) Cylinders shall be kept far enough away from the actual welding or cutting operation so that sparks, hot slag, or flame will not reach them. When this is impractical, fire resistant shields shall be provided. (i) LP-Gas vessels used for roofer's tar pots, plumber's pots and torches, space heaters, etc., shall be so installed that heat from the burner will not increase the temperature of the tank more than 10 degrees Fahrenheit after one hour of operation of the burner at full capacity. (j) LP-Gas vessels installed on mobile equipment shall have the bottom of the container, and/or any outlet connection, not lower than the lowest horizontal edge of the vehicle axle when fully loaded. Such units shall be adequately secured to prevent jarring loose, slipping, or rotating. (k) Use of Fuel Gas. (1) The employer shall instruct employees in the safe use of fuel gas. (2) Before a regulator to a cylinder valve is connected, the valve shall be opened slightly and closed immediately. (This action is generally termed "cracking" and is intended to clear the valve of dust or dirt that might otherwise enter the regulator.) (3) The person cracking the valve shall stand to one side of the outlet, not in front of it. The valve of a fuel gas cylinder shall not be cracked where the gas would reach welding work, sparks, flame, or other possible sources of ignition. (l) The cylinder valve shall be opened slowly to prevent damage to the regulator. For quick closing, valves on fuel gas cylinders shall not be opened more than 1 1/2 turns. When a special wrench is required, it shall be left in position on the stem of the valve while the cylinder is in use so that the fuel gas flow can be shut off quickly in case of an emergency. In the case of manifolded or coupled cylinders, at least one such wrench shall be available for immediate use. Nothing shall be placed on top of a fuel gas cylinder, when in use, which may damage the safety device or interfere with the quick closing of the valve. (m) When the valve on a fuel gas cylinder is opened and there is found to be a leak around the valve stem, the valve shall be closed and the gland nut tightened. If this action does not stop the leak, the use of the cylinder shall be discontinued, and it shall be properly tagged and removed from the work area. In the event that fuel gas should leak from the cylinder valve, rather than from the valve stem, and the gas cannot be shut off, the cylinder shall be properly tagged and taken outdoors, to an isolated area, away from personnel and sources of ignition. The supplier shall promptly be notified of the leaking cylinder valve and the supplier's instructions shall be followed. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1741. Pressure Regulators. Regulators that reduce the vapor pressure of fuel gas to not more than 20 psi are required for all installations within structures or confined spaces unless the burner or appliance specifically requires a higher pressure and equivalent safety is provided. The use of regulators or automatic pressure-reducing valves shall be limited to the pressures and the types of gases for which they were designed. Regulators are required for installations where a fuel gas hose is between fuel source and burner. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1742. Hose and Connections. (a) Fuel gas hose and oxygen hose shall be easily distinguished from each other. Note: The contrast may be made by different colors or by surface characteristics readily distinguishable by the sense of touch. (b) A single hose having more than 1 gas passage shall not be used as a connection between torch and gas outlet if a wall failure would permit the flow of either gas into the other passage. (c) Hoses used for liquefied petroleum gas, such as butane or propane, shall be of, or lined with, materials that are resistant to the action of LP-Gas. They shall be designed for a bursting pressure of at least 1,250 psi, and shall be marked every 5 feet with the letters "LPG." Hoses over 1/2 inch diameter shall also be marked with the manufacturer's name. (d) The connection between fuel source and burner shall be with extra heavy steel pipe (Schedule 80), flexible metallic tubing or hose suitable for the service, and where exposed shall be protected against physical damage. (e) When not in use, manifold and header hose connections shall be capped. (f) When parallel sections or oxygen and fuel gas hose are taped together, not more than 4 inches out of 12 inches shall be covered by tape. (g) Hose couplings shall be of the type that cannot be unlocked or disconnected by means of a straight pull without rotary motion. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 1743. General Precautions. (a) No device or attachment facilitating or permitting mixture of air or oxygen with combustible gases prior to consumption, except at the burner or in a standard torch or blowpipe, shall be allowed unless approved for the purpose. (b) Acetylene shall not be generated or utilized at a pressure in excess of 15 pounds per square inch gauge pressure. Exception: Acetylene dissolved in suitable solvent and stored in cylinders manufactured according to Interstate Commerce Commission requirements. (c) Oxygen cylinders and fittings shall be kept away from oil or grease. Cylinders, cylinder caps and valves, couplings, regulators, hose, and apparatus shall be kept free from oil or greasy substances and shall not be handled with oily hands or gloves. Oxygen shall not be directed at oily surfaces, greasy clothes, or within a fuel oil or other storage tank or vessel. (d) Hose piping systems, apparatus, and fittings shall not be used. (e) Oxygen shall never be used from a cylinder or cylinder manifold unless a pressure-reducing device intended for use with oxygen, and so marked, is provided. (f) Acetylene shall never be brought into contact with unalloyed copper except in a blowpipe or torch. (g) Cylinders not having fixed hand wheels shall have keys, handles or nonadjustable wrenches on valve stems while these cylinders are in service. In multiple cylinder installations only one key or handle is required for each manifold. (h) Cylinders shall never be used as rollers or supports whether full or empty. (i) Compressed oxygen shall not be used for ventilation, testing, or similar purposes different from its intended function in welding and burning. (j) A dry chemical or carbon dioxide fire extinguisher rated at least 10 B:C shall be kept near operations where bottled fuel gases are being used. (k) LP-Gas vessels shall be kept in a position so that the safety relief valve is in direct contact with the vapor space in the vessel at all times. ( l) When operations are suspended for any substantial period of time, such as during lunch or overnight, gas cylinders shall be shut off. The torch and hose shall be removed from the confined space. Upon completion or discontinuance of welding operations, the welder shall warn other workers of the location of hot metal. Note: Authority cited: Section 142.3, Labor Code.

Demonstrate your interest in safety by establishing a firm and positive accident prevention policy that includes the supplying of tangible items like hard hats, good ladders, first aid materials, and safety devices on equipment. 2. Provide that capable, responsible supervisors make regular inspections of all excavations, forms, scaffolds, stairs, ladders, structures, machinery, and equipment at frequent intervals; take immediate corrective measures to eliminate hazards directly under control of the employer, or report violations of Safety Orders and safe practices to the responsible employer. 3. Make certain that the foremen assume their share of the responsibility for accidents, and require a written report from them on each. Require that each report suggests a feasible means of avoiding future accidents of a similar nature. 4. Monthly, or more frequent, meetings of all foremen should be held under direction of the superintendent for a discussion of safety problems and accidents that have occurred. Have something specific ready for discussion, such as safety regulations, or any changes in equipment and methods that are to be adopted for safety reasons. 5. Display safety posters and warning signs. A sign indicating how many consecutive accident-free days have passed is often worthwhile. 6. Consider the advisability of posting a list of all foremen who have kept their crews accident free for a certain period of time. 7. Consider the advisability of establishing various forms of safety competition, including suitable rewards or recognition to individuals and crews with good records. 8. Require foremen to give individual safety instructions and orders, as needed, to new workers and those found to be working unsafely. 9. Consider the advisability of having the foremen call short "toolbox" or "tail-gate" safety meetings with their crews about once a week on the job, to emphasize some particular safety problem that needs special attention. 10. Keep track of your safety record and keep everyone posted as to progress. A graph or chart, indicating gains or losses, is good for this purpose. 11. Encourage safety suggestions from all workers and, if the suggestion cannot be followed promptly, explain why to the worker. 12. Consider the advisability of giving each worker a copy of certain important safety rules that they are expected to follow. 13. Arrange for frequent and regular field safety inspections.

These classified locations are assigned six designations as follows: Class I, Division 1 Class I, Division 2 Class II, Division 1 Class II, Division 2 Class III, Division 1 Class III, Division 2 (Title 24, Part 3, Section 3-500-1(a).) (a) Class I locations. Class I locations are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class I locations include those specified in (1) and (2) following: (1) Class I, Division 1. A Class I, Division 1 location is a location: (A) In which hazardous concentrations of flammable gases or vapors exist continuously, intermittently, or periodically under normal operating conditions; or (B) In which hazardous concentrations of such gases or vapors may exist frequently because of repair or maintenance operations or because of leakage; or (C) In which breakdown or faulty operation of equipment or processes might release hazardous concentrations of flammable gases or vapors, and might also cause simultaneous failure of electric equipment. Note: This classification usually includes locations where volatile flammable liquids or liquefied flammable gases are transferred from one container to another, interiors of spray booths and areas in the vicinity of spraying and painting operations where volatile flammable solvents are used: locations containing open tanks or vats of volatile flammable liquids; drying rooms or compartments for the evaporation of flammable solvents; locations containing fat and oil extraction equipment using volatile flammable solvents; portions of cleaning and dyeing plants where hazardous liquids are used; gas generator rooms and other portions of gas manufacturing plants where flammable gas may escape; inadequately ventilated pump rooms for flammable gas or for volatile flammable liquids; the interiors of refrigerators and freezers in which volatile flammable materials are stored in open, lightly stoppered, or easily ruptured containers; and all other locations where hazardous concentrations of flammable vapors or gases are likely to occur in the course of normal operations. (2) Class I, Division 2. A Class I, Division 2 location is a location: (A) In which volatile flammable liquids or flammable gases are handled, processed, or used, but in which the hazardous liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems, or in case of abnormal operation of equipment; or (B) in which hazardous concentrations of gases or vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operations of the ventilating equipment; or (C) that is adjacent to a Class I, Division 1 location, and to which hazardous concentrations of gases or vapors might occasionally be communicated unless such communication is prevented by adequate positive-pressure ventilation from a source of clean air, and effective safeguards against ventilation failure are provided. Note: This classification usually includes locations where volatile flammable liquids or flammable gases or vapors are used, but which would become hazardous only in case of an accident or of some unusual operating condition. The quantity of hazardous materials that might escape in case of accident, the adequacy of ventilating equipment, the total area involved, and the record of the industry or business with respect to explosions or fires are all factors that merit consideration in determining the classification and extent of each location. Piping without valves, checks, meters, and similar devices would not ordinarily introduce a hazardous condition even though used for hazardous liquids or gases. Locations used for the storage of hazardous liquids or of liquefied or compressed gases in sealed containers would not normally be considered hazardous unless subject to other hazardous conditions also. Electrical conduits and their associated enclosures separated from process fluids by a single seal or barrier are classed as a Division 2 location if the outside of the conduit and enclosures is a non-hazardous location. (Title 24, Part 3, Section 500-4.) (b) Class II Locations. Class II locations are those that are hazardous because of the presence of combustible dust. Class II locations include those specified in (1) and (2) following: (1) Class II, Division 1. A Class II, Division 1 location is a location: (A) In which combustible dust is or may be in suspension in the air continuously, intermittently, or periodically under normal operating conditions, in quantities sufficient to produce explosive or ignitable mixtures; or (B) Where mechanical failure or abnormal operation of machinery or equipment might cause such explosive or ignitable mixtures to be produced, and might also provide a source of ignition through simultaneous failure of electric equipment, operation of protection devices, or from other causes; or (C) In which combustible dusts of an electrically conductive nature may be present. Note: This classification usually includes the working areas of grain handling and storage plants; rooms containing grinders or pulverizers, cleaners, graders, scalpers, open conveyors or spouts, open bins or hoppers, mixers or blenders, automatic or hopper scales, packing machinery, elevator heads and boots, stock distributors, dust and stock collectors (except all-metal collectors vented to the outside), and all similar dust-producing machinery and equipment in grain-processing plants, starch plants, sugar-pulverizing plants, malting plants, hay grinding plants, and other occupancies of similar nature; coal-pulverizing plants (except where the pulverizing equipment is essentially dust-tight); all working areas where metal dusts and powders are produced, processed, handled, packed, or stored (except in tight containers); and all other similar locations where combustible dust may, under normal operating conditions, be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Combustible dusts which are electrically nonconductive include dusts produced in the handling and processing of grain and grain products, pulverized sugar and cocoa, dried egg and milk powders, pulverized spices, starch and pastes, potato and woodflour, oil meal from beans and seed, dried hay, and other organic materials which may produce combustible dusts when processed or handled. Electrically conductive nonmetallic dusts include dusts from pulverized coal, coke, carbon black, and charcoal. Dusts containing magnesium or aluminum are particularly hazardous and the use of extreme precaution will be necessary to avoid ignition and explosion. (2) Class II, Division 2. A Class II, Division 2 location is a location in which combustible dust will not normally be in suspension in the air or will not be likely to be thrown into suspension by the normal operation of equipment or apparatus in quantities sufficient to produce explosive or ignitable mixtures, but: (A) Where deposits or accumulations of such combustible dust may be sufficient to interfere with the safe dissipation of heat from electric equipment or apparatus; or (B) Where such deposits or accumulations of combustible dust on, in, or in the vicinity of electric equipment might be ignited by arcs, sparks, or burning material from such equipment. Note: Locations where dangerous concentrations of suspended dust would not be likely, but where dust accumulations might form on, or in the vicinity of electric equipment, would include rooms and areas containing only closed spouting and conveyors, closed bins or hoppers, or machines and equipment from which appreciable quantities of dust would escape only under abnormal operating conditions; rooms or areas adjacent to a Class II, Division 1 location as described in (1)(B) above, and into which explosive or ignitable concentrations of suspended dust might be communicated only under abnormal operating conditions; rooms or areas where the formation of explosive or ignitable concentrations of suspended dust is prevented by the operation of effective dust control equipment; warehouses and shipping rooms where dust-producing materials are stored or handled only in bags or containers; and other similar locations. (Title 24, Part 3, Section 500-5.) (c) Class III Locations. Class III locations are those that are hazardous because of the presence of easily ignitable fibers or flyings but in which such fibers or flyings are not likely to be in suspension in the air in quantities sufficient to produce ignitable mixtures. Class III locations include those specified in (1) and (2) following: (1) Class III, Division 1. A Class III, Division 1 location is a location in which easily ignitable fibers or materials producing combustible flyings are handled, manufactured, or used.

Electronic News Gathering (ENG). A task or series of tasks applied to capturing news, sporting or other live events on location using cameras and support equipment and using recorded media for live transmission and/or reception. For the purposes of this regulation, ENG includes Satellite News Gathering (SNG), Electronic Field Production (EFP), and other activities which are functionally similar to ENG. ENG Vehicle. An ENG vehicle has a transmitter and may also have a receiver. An ENG vehicle employs an elevating antenna, dish, laser, or similar device or structure in order to transmit, receive, or relay video, audio, or data signal to or from a broadcasting station, fixed or mobile relay point, including satellite or other spacecraft, or other facility for immediate or delayed processing for use in broadcasts or closed circuit transmission. Excluded from this Article are mobile cellular telephone sites, sometimes referred to as cells-on-wheels (COWS) used exclusively for cellular telephone communications. Step potential. "Step potential" is the voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the "electrode." A person could be at risk of injury during a fault simply by standing near the grounding point. Touch potential. "Touch potential" is the voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the energized object and a point some distance away. It should be noted that the touch potential could be nearly the full voltage across the grounded object if that object is grounded at a point remote from the place where the person is in contact with it. Step and touch potentials are illustrated in Figure 1. Figure 1 - Step and Touch Potentials Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 2981.

Wedge clamp safeties shall not be used for counterweight safeties unless they are arranged to be reset from the pit or the machine room. (e) Identification and Classification of Types of Safeties. Car safety devices (safeties) are identified and classified on the basis of performance characteristics after the safety begins to apply pressure on the guide rails. On this basis, there are three types of safeties. (1) Type A Safeties. Safeties which develop a rapidly increasing pressure on the guide rails during the stopping interval, the stopping distance being very short due to the inherent design of the safety. The operating force is derived entirely from the mass and the motion of the car or the counterweight being stopped. These safeties apply pressure on the guide rails through eccentrics, rollers, or similar devices, without any flexible medium purposely introduced to limit the retarding force and increase the stopping distance. (2) Type B Safeties. Safeties which apply limited pressure on the guide rails during the stopping interval, and which provide stopping distances that are related to the mass being stopped and the speed at which application of the safety is initiated. Retarding forces are reasonably uniform after the safety is fully applied. Continuous tension in the governor rope may or may not be required to operate the safety during the entire stopping interval. Minimum and maximum distances are specified on the basis of governor tripping speed. (3) Type C Safeties (Type A with Oil Buffers).

(A) Single-Reversible Tramway. A tramway having a single carrier, or single group of carriers, that moves back and forth between terminals on a single path of travel. This type is sometimes called "to-and-fro" aerial tramway. (B) Double-Reversible Tramway. A tramway having two carriers, or two groups of carriers, that oscillate back and forth between terminals on two paths of travel. This type is sometimes called "jig-back" aerial tramway. (2) Aerial Lift. A tramway on which passengers are transported in gondolas or on chairs that circulate around terminals without reversing the travel path. (A) Detachable Grip Lifts. A detachable grip lift is an aerial lift on which carriers alternately attach to and detach from a moving haul rope. The tramway system may be monocable or bicable. (B) Fixed Grip Lifts. A fixed grip lift is an aerial lift in which carriers remain attached to a haul rope. The tramway system may be either continuous or intermittent circulating, and either monocable or bicable. (c) Surface Lifts. A surface lift is a tramway on which the passengers are propelled by means of a circulating overhead wire rope while remaining in contact with the ground or snow surface. Transportation is limited to one direction. Connection between the passengers and the wire rope is by means of a device attached to and circulating with the haul rope known as a "towing outfit." Surface lifts include T-bars, J-bars, and platters. (1) T-bar Lifts. That type of lift on which the device between the haul rope and passengers forms the shape of an inverted "T" propelling passengers located on both sides of the stem of the "T." (2) J-bar Lifts.

(3) Platter Lifts. That type of lift on which the device between the haul rope and passenger is a single stem with a platter (or disk) attached to the lower end of the stem, propelling the passenger astride the stem of the platter (or disk). (d) Rope Tows. A rope tow is a tramway on which the passengers grasp the circulating haul rope, or a handle attached to a circulating rope, and are propelled by the circulating haul rope while remaining in contact with the ground or snow surface. The haul rope remains adjacent to the track of the passengers and at an elevation that permits them to maintain their grasp on the haul rope, or handle, throughout that portion of the tow length that is designed to be traveled. (1) Fiber Rope Tow. A tow having a fiber (natural or synthetic) haul rope. (2) Wire Rope Tow. A tow having a metallic haul rope. Note: Authority cited: Section 142.3, Labor Code.

Whenever access to employee medical records is requested in accordance with section 3204(e)(2)(B)1 or 2, a physician representing the employer may recommend that the employee or designated representative: consult with the physician for the purposes of reviewing and discussing the records requested; accept a summary of material facts and opinions in lieu of the records requested; or accept release of the requested records only to a physician or other designated representative. 4. Whenever an employee requests access to his or her employee medical records and a physician representing the employer believes that direct employee access to information contained in the records regarding a specific diagnosis of a terminal illness or a psychiatric condition could be detrimental to the employee's health, the employer may deny the employee's request for direct access to this information only, and the employer shall inform the employee that access will only be provided to a designated representative of the employee having specific written consent. 5. Where a designated representative with specific written consent requests access to information withheld in accordance with section 3204(e)(2)(B)4, the employer shall assure the access of the designated representative to this information even when it is known that the designated representative will give the information to the employee. NOTE: Nothing in this section precludes a physician, nurse, or other responsible health care personnel maintaining employee medical records from deleting from requested medical records the identity of a family member, personal friend, or fellow employee who has provided confidential information concerning an employee's health status. (C) Analyses Using Exposure or Medical Records. 1. Each employer shall, upon request, assure the access of each employee and designated representative to each analysis using exposure or medical records concerning the employee's working conditions or workplace. 2. Whenever access is requested to an analysis which reports the contents of employee medical records by either direct identifier (name, address, social security number, payroll number, etc.) or by information which could reasonably be used under the circumstances indirectly to identify specific employees (exact age, height, weight, race, sex, date of initial employment, job title, etc.), the employer shall assure that personal identifiers are removed before access is provided. If the employer can demonstrate that removal of personal identifiers from an analysis is not feasible, access to the personally identifiable portions of the analysis need not be provided. (3) Division of Occupational Safety and Health Access. (A) Each employer shall, upon request, and without derogation of any rights under the Constitution of the United States, the Constitution of the State of California or the California Occupational Safety and Health Act of 1973, Labor Code sections 6300 et seq., that the employer chooses to exercise, assure the prompt access of representatives of the Chief of the Division of Occupational Safety and Health (DOSH) to employee exposure and medical records and to analyses using exposure or medical records. (B) Whenever DOSH seeks access to personally identifiable employee medical information by presenting to the employer a written access order, the employer shall prominently post a copy of the written access order and its accompanying cover letter for at least fifteen (15) working days. (f) Trade Secrets. (1) Except as provided in section 3204(f)(2), nothing in this section precludes an employer from deleting from records requested by a health professional, an employee or designated representative any trade secret data which discloses manufacturing processes, or discloses the percentage of a chemical substance in a mixture, as long as the health professional, employee or designated representative is notified that such information has been deleted. Whenever deletion of trade secret information substantially impairs evaluation of the place where or the time when exposure to a toxic substance or harmful physical agent occurred, the employer shall provide alternative information which is sufficient to permit the requesting party to identify where and when exposure occurred. (2) The employer may withhold the specific chemical identity, including the chemical name and other specific identification of a toxic substance from a disclosable record provided that: (A) Evidence is included to support the claim that the information withheld is a trade secret; (B) All other available information on the properties and effects of the toxic substance is disclosed; (C) The employer informs the requesting party that the specific chemical identity is being withheld as a trade secrete; and (D) The specific chemical identity is made available to health professionals, employees and designated representatives in accordance with the specific applicable provisions of this subsection, section 3204(f). (3) Where a treating physician or nurse determines that a medical emergency exists and the specific chemical identity of a toxic substance is necessary for emergency or first-aid treatment, the employer shall immediately disclose the specific chemical identity of a trade secret chemical to the treating physician or nurse, regardless of the existence of a written statement of need or a confidentiality agreement. The employer may require a written statement of need and confidentiality agreement, in accordance with the provisions of section 3204(f)(4) and (f)(5), as soon as circumstances permit. (4) In non-emergency situations, an employer shall, upon request, disclose a specific chemical identity, otherwise permitted to be withheld under section 3204(f)(2), to a health professional, employee, or designated representative if: (A) The request is in writing; (B) The request describes with reasonable detail one or more of the following occupational health needs for the information: 1. To assess the hazards of the chemicals to which employees will be exposed; 2. To conduct or assess sampling of the workplace atmosphere to determine employee exposure levels; 3. To conduct pre-assignment or periodic medical surveillance of exposed employees; 4. To provide medical treatment to exposed employees; 5. To select or assess appropriate personal protective equipment for exposed employees; 6. To design or assess engineering controls or other protective measures for exposed employees; and 7. To conduct studies to determine the health effects of exposure. (C) The request explains in detail why the disclosure of the specific chemical identity is essential and that in lieu thereof, the disclosure of the following information would not enable the health professional, employee or designated representative to provide the occupational health services described in section 3204(f)(4)(B): 1. The properties and effects of the chemical; 2. Measures for controlling worker's exposure to the chemical; 3. Methods of monitoring and analyzing worker's exposure to the chemical; and 4. Methods of diagnosing and treating harmful exposures to the chemical. (D) The request includes a description of the procedures to be used to maintain the confidentiality of the disclosed information; and (E) The health professional, employee or designated representative and the employer or contractor of the services of the health professional or designated representative agree in a written confidentiality agreement that the health professional, employee or designated representative will not use the trade secret information for any purpose other than the health needs(s) asserted and agree not to release the information under any circumstances other than to DOSH, as provided in section 3204(f)(9), except as authorized by the terms of the agreement or by the employer. (5) The confidentiality agreement authorized by section 3204(f)(4)(D): (A) May restrict the use of the information to the health purposes indicated in the written statement of need; (B) May provide for appropriate legal remedies in the event of a breach of the agreement, including stipulation of a reasonable pre-estimate of likely damages; and (C) May not include requirements for the posting of a penalty bond. (6) Nothing in this section is meant to preclude the parties from pursuing non-contractual remedies to the extent permitted by law. (7) If the health professional, employee or designated representative receiving the trade secret information decides that there is a need to disclose it to DOSH, the employer who provided the information shall be informed by the health professional prior to, or at the same time as, such disclosure. (8) If the employer denies a written request for disclosure of a specific chemical identity, the denial must: (A) Be provided to the health professional, employee or designated representative within thirty days of the request: (B) Be in writing; (C) Include evidence to support the claim that the specific chemical identity is a trade secret; (D) State the specific reasons why the request is being denied; and (E) Explain in detail how alternative information may satisfy the specific medical or occupational health need without revealing the specific chemical identity. (9) The health professional, employee or designated representative whose request for information is denied under section 3204(f)(4) may re fer the request and the written denial of the request to DOSH for consideration. (10) When a health professional, employee or designated representative refers a denial to DOSH under section 3204(f)(9), DOSH shall consider the evidence to determine if: (A) The employer has supported the claim that the specific chemical identity is a trade secret; (B) The health professional, employee or designated representative has supported the claim that there is a medical or occupational health need for the information; and (C) The health professional, employee or designated representative has demonstrated adequate means to protect the confidentiality. (11) (A) If DOSH determines that the specific chemical identity requested under section 3204(f)(4) is not a bona fide trade secret, or that it is a trade secret but the requesting health professional, employee or designated representative has a legitimate medical or occupational health need for the information and has executed a written confidentiality agreement with adequate means for complying with the terms of such agreement, the employer will be subject to citation by DOSH. (B) If an employer demonstrates to DOSH that the execution of a confidentiality agreement would not provide sufficient protection against the potential harm from the unauthorized disclosure of a specific chemical identity trade secret, the Chief of DOSH may issue such orders or impose such additional limitations or conditions upon the disclosure of the requested chemical information as may be appropriate to assure that the occupational health needs are met without an undue risk of harm to the employer. (12) Notwithstanding the existence of a trade secret claim, and employer shall, upon request, disclose to the Chief of DOSH any information which this section requires the employer to make available. Where there is a trade secret claim, such claim shall be made no later than at the time the information is provided to the Chief of DOSH so that dutiable determinations of trade secret status can be made and the necessary protection can be implemented. (13) Nothing in this section shall be construed as requiring the disclosure under any circumstances of process or percentage of mixture information which is a trade secret. (g) Employee Information. (1) Upon an employee's first entering into employment, and at least annually thereafter, each employer shall inform current employees covered by this section of the following: (A) The existence, location, and availability of any records covered by this section; (B) The person responsible for maintaining and providing access to records; and (C) Each employee's rights of access to these records. (2) Each employer shall keep a copy of this section and its appendices and make copies readily available, upon request, to employees. The employer shall also distribute to current employees any informational materials concerning this section which are made available to the employer by the Chief of DOSH. (h) Transfer of Records. (1) Whenever an employer is ceasing to do business, the employer shall transfer all records subject to this section to the successor employer. The successor employer shall receive and maintain these records. (2) Whenever an employer is ceasing to do business and there is no successor employer to receive and maintain the records subject to this standard, the employer shall notify affected employees of their rights of access to records at least three (3) months prior to the cessation of the employer's business. (3) Whenever an employer either is ceasing to do business and there is no successor employer to receive and maintain the records, or intends to dispose of any records required to be preserved for at least thirty (30) years, the employer shall: (A) Transfer the records to the Director of the National Institute for Occupational Safety and Health (NIOSH) if so required by a specific occupational safety and health standard; or (B) Notify the Director of NIOSH in writing of the impending disposal of records at least three (3) months prior to the disposal of the records. (4) Where an employer regularly disposes of records required to be preserved for at least thirty (30) years, the employer may, with at least three (3) month's notice, notify the Director of NIOSH on an annual basis of the records intended to be disposed of in the coming year.

[Your right of access to a specific written consent form submitted to your employer is provided by section 3204(e)(1)(D).] Full name of Employee or Legal Representative __________ Signature of Employee or Legal Representative __________ Date of Signature __________ Appendix B Availability of NIOSH Registry of Toxic Effects of Chemical Substances (RTECS) Section 3204 applies to all employee exposure and medical records, and analyses thereof, of employees exposed to toxic substances or harmful physical agents [subsection (b)(2)]. The term "toxic substance or harmful physical agent" is defined by section 3204(c)(13) to encompass chemical substances, biological agents, and physical stresses for which there is evidence of harmful health effects. The regulation uses the latest printed edition of the National Institute for Occupational Safety and Health (NIOSH) Registry of Toxic Effects of Chemical Substances (RTECS) as one of the chief sources of information as to whether evidence of harmful health effects exists. If a substance is listed in the latest printed RTECS, the regulation applies to exposure and medical records (and analyses of these records) relevant to employees exposed to the substance. It is appropriate to note that the regulation does not require that employers purchase a copy of RTECS; and many employers need not consult RTECS to ascertain whether their employee exposure or medical records are subject to the regulation. Employers who do not currently have the latest printed edition of the NIOSH RTECS, however, may desire to obtain a copy. The RTECS is issued in an annual printed edition as mandated by section 20(a)(6) of the Occupational Safety and Health Act [29 U.S.C. 669(a)(6)]. The Introduction to the 1980 printed edition describes the RTECS as follows: "The 1980 edition of the Registry of Toxic Effects of Chemical Substances, formerly known as the Toxic Substances list, is the ninth revision prepared in compliance with the requirements of section 20(a)(6) of the Occupational Safety and Health Act of 1970 (Public Law 91-596). The original list was completed on June 28, 1971, and has been updated annually in book format. Beginning in October 1977, quarterly revisions have been provided in microfiche. This edition of the Registry contains 168,096 listings of chemical substances: 45,156 are names of different chemicals with their associated toxicity data and 122,940 are synonyms. This edition includes approximately 5,900 new chemical compounds that did not appear in the 1979 Registry." (p. xi) "The Registry's purposes are many, and it serves a variety of users. It is a single source document for basic toxicity information and for other data, such as chemical identifiers and information necessary for the preparation of safety directives and hazard evaluations for chemical substances. The various types of toxic effects linked to literature citations provide researchers and occupational health scientists with an introduction to the toxicological literature, making their own review of the toxic hazards of a given substance easier. By presenting data on the lowest reported doses that produce effects by several routes of entry in various species, the Registry furnishes valuable information to those responsible for preparing safety data sheets for chemical substances in the workplace. Chemical and production engineers can use the Registry to identify the hazards which may be associated with chemical intermediates in the development of final products, and thus can more readily select substitutes or alternate processes which may be less hazardous. Some organizations, including health agencies and chemical companies, have included the NIOSH Registry accession numbers with the listing of chemicals in their files to reference toxicity information associated with those chemicals. By including foreign language chemical names, a start has been made toward providing rapid identification of substances produced in other countries." (p. xi) "In this edition of the Registry, the editors intend to identify 'all known toxic substances' which may exist in the environment and to provide pertinent data on the toxic effects from known doses entering an organism by any route described." (p. xi) "It must be reemphasized that the entry of a substance in the Registry does not automatically mean that it must be avoided. A listing does mean, however, that the substance has the documented potential of being harmful if misused, and care must be exercised to prevent tragic consequences. Thus, the Registry lists many substances that are common in everyday life and are in nearly every household in the United States. One can name a variety of such dangerous substances: prescription and non-prescription drugs; food additives; pesticide concentrates, sprays, and dusts; fungicides; herbicides; paints; glazes, dyes; bleaches and other household cleaning agents; alkalies; and various solvents and diluents. The list is extensive because chemicals have become an integral part of our existence." (p. xiv) The RTECS printed edition may be purchased from the Superintendent of Documents, U.S. Government Printing Office (GPO), Washington, D.C. 20402 (202- 783-3238). Some employers may also desire to subscribe to the quarterly update to the RTECS which is published in a microfiche edition. An annual subscription to the quarterly microfiche may be purchased from the GPO (Order the "Microfiche Edition, Registry of Toxic Effects of Chemical Substances "). Both the printed edition and the microfiche edition of RTECS are available for review at many university and public libraries throughout the country. The latest RTECS editions may also be examined at the OSHA Technical Data Center, Room N2439 - Rear, United States Department of Labor, 200 Constitution Avenue, N.W., Washington, D.C. 20210 (202-523-9700), or at any OSHA Regional or Area Office (See, major city telephone directories under United States Government -Labor Department).

Note: Local building regulations may require 9-inch spacing of midrails. (b) All guardrails and other permissible types, including their connections and anchorage, shall be designed for a live load of 20 pounds per linear foot applied either horizontally or vertically downward at the top rail. Dimensional details of railing members of a few types of construction which comply with this strength requirement are given hereinafter in subsection (c). Note: It is recognized that the minimum value of railing strength here specified is inadequate for safety under operating conditions where railings are liable to receive heavy stresses from crowds, trucking, handling materials, etc. For such conditions, additional strength shall be provided by use of heavier stock, closer spacing of posts, bracing, or otherwise. Railing members shall be framed in such a position that they will afford the greatest support and protection, for example, top rails of structural steel angles shall have the outside face of vertical leg located on the side adjacent to the side of normal contact by the employee. (Title 24, Part 2, Section 2- 1716(b).) (c) The following are some acceptable guardrail specifications: other combinations will be accepted as long as equivalent strength and protection are maintained. (1) In wooden construction, the posts to be of at least 2-inch by 4-inch nominal material spaced not to exceed 6 feet, the top rails to be smooth with corners rounded and not less than 2-inch by 4-inch nominal material. The posts may be spaced on 8-foot centers if the top rails consist of double 1-inch by 4- inch nominal boards, provided that 1 board is fastened in a flat position on top of the posts and the other is fastened in an edge-up position to the inside of the posts and the side of the top board. Single midrails, where permitted, shall be not less than 2-inch by 4-inch nominal material and installed on the contact side of the guardrail. (2) If constructed of standard metal pipe, the top rails and single midrail, where permitted, to be 1 1/2-inch outside diameter or larger. The posts to be 1 1/2-inch outside diameter or larger, the spacing not to exceed 8 feet. (3) If constructed of structural metal, the top rails to be angle iron of at least 2-inch by 2-inch by 1/4-inch angles or other metal shapes of equivalent bending strength; and the single midrail, where permitted, to be iron or steel of at least 2-inch by 2-inch by 1/4-inch angles or other metal shapes of equivalent strength. The posts to be angle iron of at least 2-inch by 2-inch by 1/4-inch stock, the spacing not to exceed 8 feet. (Title 24, Part 2, Section 2- 1716(c).) (d) Where toeboards are required, they shall be constructed of wood, concrete, metal, or other suitable material. Where constructed of metal grille, mesh shall not exceed 1-inch. The top of the toeboard shall be not less than 3 1/2 inches above the platform, walkway, or other working level and the bottom clearance shall not exceed 1/4-inch. Note: Where materials are piled, higher toeboards, or paneling from floor to intermediate rails or top rail shall be provided where necessary for safety. (Title 24, Part 2, Section 2-1753.)

(a) All fixed ladders shall be approved as defined in Section 3206 of the General Industry Safety Orders. (b) Definitions. Cage. A cage is a guard that may be referred to as a cage or basket guard, which is an enclosure that is fastened to the side rails of the fixed ladder or to the structure to encircle the climbing space of the ladder for the safety of the person who must climb the ladder. Cleats. Cleats are ladder crosspieces of rectangular cross section placed on edge on which a person may step in ascending or descending. Fastenings. A fastening is a device to attach a ladder to a structure, building, or equipment. Fixed, hinged, bearing, or slide-type fastenings may be used. Fixed Ladder. A fixed ladder is a ladder permanently attached to a structure, building, or equipment. Ladders referred to in this code shall be construed to be fixed ladders. Grab Bars. Grab bars are individual handholds placed adjacent to or as an extension above ladders for the purpose of providing access beyond the limits of the ladder. Individual-Rung Ladder. An individual-rung ladder is a fixed ladder each rung of which is individually attached to a structure, building, or equipment. Ladder. A ladder is an appliance usually consisting of two side rails joined at regular intervals by crosspieces called steps, rungs, or cleats, on which a person may step in ascending or descending. Ladder Safety Device. A ladder safety device is any device, other than a cage or well, designed to eliminate or reduce the possibility of accidental falls and which may incorporate such features as life belts, friction brakes, and sliding attachments. Pitch. Pitch is the included angle between the horizontal and the ladder, measured on the opposite side of the ladder from the climbing side. Rail Ladder. A rail ladder is a fixed ladder consisting of side rails joined at regular intervals by rungs or cleats and fastened in full length or in sections to a building, structure, or equipment. Railings. Railings when referred to in this section shall be any one or a combination of those railings defined in Section 3210. Rungs. Rungs are ladder crosspieces on which a person may step in ascending or descending. Side-Step Ladder. A side-step ladder is one from which a person getting off at the top must step sideways from the ladder in order to reach the landing, such as shown in Fig. 3. Steps. Steps are the flat crosspieces of a ladder on which a person may step in ascending or descending. Through Ladder. A through ladder is one from which a person getting off at the top must step through the ladder in order to reach the landing, such as shown in Fig. 2. Well. A well is a permanent complete enclosure around a fixed ladder, which is attached to the walls of the well. Proper clearances for a well will give the person who must climb the ladder the same protection as a cage. (See (g)(6) and Fig. 1.) (c) Design Considerations. All ladders, appurtenances, and fastenings shall be designed to meet the following load requirements: (1) The minimum design live load shall be a single concentrated load of 200 pounds. (2) The number and position of additional concentrated live-load units of 200 pounds each as determined from anticipated usage of the ladder shall be considered in the design. (3) The live loads imposed by persons occupying the ladder shall be considered to be concentrated at such point or points as will cause the maximum stress in the structural member being considered. (4) The weight of the ladder and attached appurtenances together with the live load shall be considered in the design of rails and fastenings. (5) All wood parts of fixed ladders shall meet the requirements of Section 3278. (6) For fixed ladders consisting of wood side rails and wood rungs or cleats, used at a pitch in the range 75 degrees to 90 degrees, and intended for use by no more than one person per section, single ladders or cleat ladders as described in Section 3278 are acceptable. (d) Specific Features. (1) All rungs shall have a minimum diameter of 3/4 inch for metal ladders, except as covered in (e)(1) and a minimum diameter of 1 1/8 inches for wood ladders. Materials other than steel, aluminum, and wood are acceptable provided the design, fabrication, and erection are in accordance with recognized design practice and meet the design requirements of Section 3277(c) and Section 3277(d)(11) when applicable. (2) The distance between the top surfaces of rungs, cleats, and steps shall not exceed 12 inches and shall be uniform throughout the length of the ladder. 2. The vertical distance of the first rung from ground level may be as high as 14 inches. (3) The minimum clear length of rungs or cleats shall be 16 inches. (4) Rungs, cleats, and steps shall be free of splinters, sharp edges, burrs, or projections which may be a hazard. (5) The rungs of an individual-rung ladder shall be so designed that the climber's foot cannot slide off the end of a rung. A suggested design for metal rungs is shown in Fig. 4. (6) Side Rails. Side rails which might be used as a climbing aid shall be of such cross sections as to afford adequate gripping surface without sharp edges, splinters, or burrs. (7) Fastenings. Fastenings shall be an integral part of fixed ladder design. (8) Splices. All splices made by whatever means shall meet design requirements as noted in (c). All splices and connections shall have smooth transition with original members and with no sharp or extensive projections. (9) Electrolytic Action. Adequate means shall be employed to protect dissimilar metals from electrolytic action when such metals are joined. (10) Welding. All welding shall be in accordance with procedures of the American Welding Society, or equivalent. (11) Embedment. Individual rungs of ladders installed in manholes and underground vaults having a wall thickness which will not permit at least 6 inches of embedment shall have anchoring devices that will provide the minimum design load requirements of Section 3277(c) in addition to the following requirements: (A) The minimum design live load shall be a single concentrated load of 300 pounds. (B) Steps or rungs shall be embedded in the wall a minimum distance of 3 inches. (e) Protection from Deterioration. (1) Metal. Metal ladders and appurtenances shall be painted or otherwise treated to resist corrosion and rusting when location demands. Ladders formed by individual metal rungs imbedded in concrete, which serve as access to pits and to other areas under floors, are frequently located in an atmosphere that causes corrosion and rusting. To increase rung life in such atmosphere, individual metal rungs shall have a minimum diameter of 1 inch or shall be painted or otherwise treated to resist corrosion and rusting. (2) Wood. Wood ladders, when used under conditions where decay may occur, shall be treated with a nonirritating preservative, and the details shall be such as to prevent or minimize the accumulation of water on wood parts. Wood ladders shall not be painted but may be coated with a clear sealant after inspection has assured that all requirements of 3278 have been met. Note: Paint does not act as a wood preservative. (3) Combined Materials. When different types of materials are used in the construction of a ladder, the materials used shall be so treated as to have no deleterious effect, one upon the other. (f) Clearance. (1) On fixed ladders, the perpendicular distance from the center line of the rungs to the nearest permanent object on the climbing side of the ladder shall be 36 inches for a pitch of 76 degrees, and 30 inches for a pitch of 90 degrees (Fig. 5), with minimum clearances for intermediate pitches varying between these two limits in proportion to the slope, except as provided in (3) and (7).

(Title 24, Part 2, Section 2-8503(a)5.) (6) The width of a stationary panel to be washed from the inside from an adjacent open casement window shall not be more than 2 1/2 feet. Note: Assuming that the window cleaner could work from the inside alternately from casement panels on each side of the stationary panel, this would mean that a 5 foot width of stationary panel would be the maximum width that could be handled in this manner without anchors. (Title 24, Part 2, Section 2-8503(a)6.) (7) Stationary panels up to 5 feet in width may be cleaned by standing on a sill or ledge (See Figure 1 for width and slope restrictions) while supported by anchors on each side of the panels if access is provided via an openable panel adjacent to the stationary panel. For stationary panels over 5 feet, but not exceeding 6 feet in width, the sill or ledge must be at least 10 inches wide with a slope not exceeding 5 degrees. (Title 24, Part 2, Section 2- 8503(a)7.) (8) A series of stationary panels without openable panels between shall require traveling methods utilizing a method, such as double-headed anchors, overhead trolley system, or other equivalent means of providing a continuous means for window cleaners to tie off their safety belts. (Title 24, Part 2, Section 2- 8503(a)8.) (9) Traveling on the outside of the building shall not be permitted where the sill or ledge is less than 6 feet wide unless it is possible to keep at least one window cleaner's belt terminal attached at all times. The distance between anchors shall not exceed 4 feet horizontally unless the sill or ledge is at least 12 inches wide and the slope is less than 5 degrees in which case the distance between anchors may be as much as 6 feet. This method of traveling shall not be permitted, however, if the sill or ledge is not continuous with at least 6 inches in front of the mullions or if each window unit is not readily accessible. (10) When the roof level or ledge is 8 feet or more in width, as measured from the face of the building to the danger point, no special protection, such as parapet, railing or window anchors, is required. When the distance is from 6 feet to 8 feet wide, anchors are required unless there is a railing or parapet at least 2 feet high. When the distance is less than 6 feet, anchors or equivalent protection as required by Section 3212 shall be required. (Title 24, Part 2, Section 2- 8503(a)9.) (11) Traveling methods that comply with these regulations shall not be permitted on ledges or sills less than 6 feet in width unless double-headed anchors or 2 single-headed anchors with separate usable heads are provided on each side of all windows in the series, along with at least one openable panel to afford a safe, convenient means of access. (Title 24, Part 2, Section 2- 8503(a)10.)

Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 3299. Personal Fall Protection. Employees on working platforms shall be protected by a personal fall arrest system meeting the requirements of Appendix C, Section I of this article, and as otherwise provided by these orders. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. Appendix A to Article 6 1. Use of the Appendix. Appendix A provides examples of equipment and methods to assist the employer in meeting the requirements of the indicated provision of the standard. Employers may use other equipment or procedures which conform to the requirements of the standard. This appendix neither adds to nor detracts from the mandatory requirements set forth in Article 6. 2. Assurance. Section 3292(c) requires the building owner to inform the employer in writing that the powered platform installation complies with certain requirements of the article, since the employer may not have the necessary information to make these determinations. The employer, however, remains responsible for meeting these requirements which have not been set off in Section 3292(c)(1). 3. Design Requirements. The design requirements for each installation should be based on the limitations (stresses, deflections, etc.), established by nationally recognized standards as promulgated by the following organizations, or to equivalent standards: AA-The Aluminum Association 818 Connecticut Avenue, N.W. Washington, DC 20006 Aluminum Construction Manual Specifications For Aluminum Structures Aluminum Standards and Data AGMA-American Gear Manufacturers Association 101 North Fort Meyer Dr., Suite 1000 Arlington, VA 22209 AISC-American Institute of Steel Construction 400 North Michigan Avenue Chicago, IL 60611 ANSI-American National Standards Institute, Inc. 11 West 42nd Street New York City, NY 10036 ASCE-American Society of Civil Engineers 345 East 47th Street New York, NY 10017 ASME-American Society of Mechanical Engineers 345 East 47th Street New York, NY 10017 ASTM-American Society for Testing and Materials 1916 Race Street Philadelphia, PA 19103 AWS-American Welding Society, Inc.

Tie-in Guides. Indented mullions, T-rails or other equivalent guides are acceptable as tie-in guides in a building face for a continuous stabilization system. Internal guides are embedded in other building members with only the opening exposed (see Figure 1 of Appendix B). External guides, however, are installed external to the other building members and so are fully exposed. The minimum opening for tie-in guides is three-quarters of an inch, and the minimum inside dimensions are one-inch deep and two inches wide. Employers should be aware of the hazards associated with tie-in guides in a continuous stabilization system which was not designed properly. For example, joints in these track systems may become extended or discontinuous due to installation, building settlement or flexing. If this problem is not corrected, the system could lam when a guide roller shoe strikes a joint or distorted area and this would cause a hazardous situation. In another instance, faulty design will result in guide rollers being mounted in a line so they will jam in the track at the slightest misalignment. 5. Building Anchors (Intermittent Stabilization System). In the selection of the vertical distance between building anchors, certain factors should be given consideration. These factors include building height and architectural design, platform length and weight, wire rope angulation, and the wind velocities in the building area. Another factor to consider is the material of the building face, since this material may be adversely affected by the building rollers. External or indented type building anchors are acceptable. Receptacles in the building facade used for the indented type should be kept clear of extraneous materials which will hinder their use. During the inspection or use of the platform system, evidence of a failure or abuse of the anchors should be brought to the attention of the employer. 6. Stabilizer Tie Length. A stabilizer tie should be long enough to provide for the planned angulation of the suspension cables. However, the length of the tie should not be excessive and become a problem by possibly becoming entangled in the building face rollers or parts of the platform machinery. The attachment length may vary due to material elongation and this should be considered when selecting the material to be used. Consideration should also be given to the use of ties which are easily installed by employees, since this will encourage their use. 7. Intermittent Stabilization System. Intermittent stabilization systems may use different equipment, tie-in devices and methods to restrict the horizontal movement of a powered platform with respect to the face of the building. One acceptable method employs corrosion-resistant building anchors secured in the face of the building in vertical rows every third floor or 50 feet, whichever is less. The anchors are spaced horizontally to allow a stabilization attachment (stabilizer tie) for each of the two platform suspension wire ropes. The stabilizer tie consists of two parts. One part is a quick connect-quick disconnect device which utilizes a corrosion-resistant yoke and retainer spring that is designed to fit over the building anchors. The second part of the stabilizer tie is a lanyard which is used to maintain a fixed distance between the suspension wire rope and the face of the building. In this method, as the suspended powered platform descends past the elevation of each anchor, the descent is halted and each of the platform occupants secures a stabilizer tie between a suspension wire rope and a building anchor. The procedure is repeated as each elevation of a building anchor is reached during the descent of the powered platform. As the platform ascends, the procedure is reversed; that is, the stabilizer ties are removed as each elevation of a building anchor is reached. The removal of each stabilizer tie is assured since theplatform is provided with stopping devices which will interrupt power to its hoist(s) in the event either stopping device contacts a stabilizer during the ascent of the platform. Figure 2 of Appendix B illustrates another type of acceptable intermittent stabilization system which utilizes retaining pins as the quick connect-quick disconnect device in the stabilizer tie. Intermittent stabilization anchors shall both be located outboard, in line with, or inboard of suspension ropes. A combination of locations at the same level shall not be allowed. 8. Wire Rope Inspection. The inspection of the suspension wire rope is important since the rope gradually loses strength during its useful life. The purpose of the inspection is to determine whether the wire rope has sufficient integrity to support a platform with the required design factor. If there is any doubt concerning the condition of a wire rope or its ability to perform the required work, the rope should be replaced. The cost of wire rope replacement is quite small if compared to the cost in terms of human injuries, equipment down time and replacement. No listing of critical inspection factors, which serve as a basis for wire rope replacement in the standard, can be a substitute for an experienced inspector of wire rope. The listing serves as a user's guide to the accepted standards by which ropes must be judged. Rope life can be prolonged if preventive maintenance is performed regularly. Cutting off an appropriate length of rope at the end termination before the core degrades and valley breaks appear minimizes degradation at these sections. 9. General Maintenance. In meeting the general maintenance requirement in Section 3297, the employer should undertake the prompt replacement of broken, worn and damaged parts, switch contacts, brushes, and short flexible conductors of electrical devices. The components of the electrical service system and traveling cables should be replaced when damaged or significantly abraded. In addition, gears, shafts, bearings, brakes and hoisting drums should be kept in proper alignment. For a stabilization system to be effective, the building face rollers cannot be dirty or greasy and shall be kept clean. 10. Training. In meeting the training requirement of Section 3298, employers should use both on the job training and formal classroom training. The written work procedures used for this training should be obtained from the manufacturer, if possible, or prepared as necessary for the employee's information and use. Employees who will operate powered platforms with intermittent stabilization systems should receive instruction in the specific ascent and descent procedures involving the assembly and disassembly of the stabilizer ties. An acceptable training program should also include employee instruction in basic inspection procedures for the purpose of determining the need for repair and replacement of platform equipment. In addition, the program should cover the inspection, care and use of the personal fall protection equipment required in Section 3299. In addition, the training program should also include an emergency action plan as specified in Section 3220 of the General Industry Safety Orders. Following the completion of a training program, the employee should be required to demonstrate competency in operating the equipment safely. Supplemental training of the employee should be provided by the employer, as necessary, if the equipment used or other working conditions should change. An employee who is required to work with chemical products on a platform should receive training in proper cleaning procedures, and in the hazards, care and handling of these products. In addition, the employee should be supplied with the appropriate personal protective equipment, such as gloves and eye and face protection. 11. Suspension and Securing of Powered Platforms (Equivalency). One acceptable method of demonstrating the equivalency of a method of suspending or securing a powered platform, as required in Sections 3294(b)(3), 3295(c) and (e)(1)(F), is to provide an engineering analysis by a professional engineer currently registered in the State of California. The analysis should demonstrate that the proposed method will provide an equal or greater degree of safety for employees than any one of the methods specified in the standard.

Paragraphs (b), (c), (d) and (e) of this Section II set forth test procedures which shall be used to determine compliance with requirements in subparagraphs (d)(1)(A) through (d)(1)(C) of Section I of this Appendix. (b) General conditions for all tests in Section II. (1) Safety lines, lanyards and deceleration devices shall be attached to an anchorage and connected to the body harness in the same manner as they would be when used to protect employees. (2) The anchorage shall be rigid, and shall not have a deflection greater than .04 inches when a force of 2,250 pounds is applied. (3) The frequency response of the load measuring instrumentation shall be 120 Hz. (4) The test weight used in the strength and force tests shall be a rigid, metal, cylindrical or torso-shaped object with a girth of 38 inches plus or minus four inches. (5) The lanyard or safety line used to create the free fall distance shall be supplied with the system, or in its absence, the least elastic lanyard or safety line available to be used with the system. (6) The test weight for each test shall be hoisted to the required level and shall be quickly released without having any appreciable motion imparted to it. (7) The system's performance shall be evaluated taking into account the range of environmental conditions for which it is designed to be used. (8) Following the test, the system need not be capable of further operation. (c) Strength Test. (1) During the testing of all systems, a test weight of 300 pounds plus or minus five pounds shall be used. (See subparagraph (b)(4), above.) (2) The test consists of dropping the test weight once. A new unused system shall be used for each test. (3) For lanyard systems, the lanyard length shall be six feet plus or minus two inches as measured from the fixed anchorage to the attachment on the body harness. (4) For rope-grab-type deceleration systems, the length of the safety line above the centerline of the grabbing mechanism to the safety line's anchorage point shall not exceed two feet. (5) For lanyard systems, for systems with deceleration devices which do not automatically limit free fall distance to two feet or less, and for systems with deceleration devices which have a connection distance in excess of one foot (measured between the centerline of the safety line and the attachment point to the body belt or harness) the test weight shall be rigged to free fall a distance of 7.5 feet from a point that is 1.5 feet above the anchorage point, to its hanging location (six feet below the anchorage). The test weight shall fall without interference, obstruction, or hitting the floor or ground during the test. In some cases, a non-elastic wire lanyard of sufficient length may need to be added to the system (for test purposes) to create the necessary free fall distance. (6) For deceleration device systems with integral safety lines or lanyards which automatically limit free fall distance to two feet or less, the test weight shall be rigged to free fall a distance of four feet. (7) Any weight which detaches from the belt or harness shall constitute failure for the strength test. (d) Force Test. (1) General. The test consists of dropping the respective test weight specified in subsection (d)(2)(A) or (d)(3)(A) once. A new, unused system shall be used for each test. (2) For lanyard systems. (A) A test weight of 220 pounds plus or minus three pounds shall be used. (See subparagraph (b)(4), above.) (B) Lanyard length shall be six feet plus or minus two inches as measured from the fixed anchorage to the attachment on the body harness. (C) The test weight shall fall free from the anchorage level to its hanging location (a total of six feet free fall distance) without interference, obstruction, or hitting the floor or ground during the test. (3) For all other systems. (A) A test weight of 220 pounds plus or minus three pounds shall be used. (See subparagraph (b)(4), above.) (B) The free fall distance to be used in the test shall be the maximum fall distance physically permitted by the system during normal use conditions, up to a maximum free fall distance for the test weight of six feet, except as follows: 1. For deceleration systems which have a connection link or lanyard, the test weight shall free fall a distance equal to the connection distance (measured between the centerline of the safety line and the attachment point to the body harness). 2. For deceleration device systems with integral safety lines or lanyards which automatically limit free fall distance to two feet or less, the test weight shall free fall a distance equal to that permitted by the system in normal use. (For example, to test a system with a self-retracting safety line or lanyard, the test weight shall be supported and the system allowed to retract the safety line or lanyard as it would in normal use. The test weight would then be released and the force and deceleration distance measured). (4) A system fails the force test if the recorded maximum arresting force exceeds 2,520 pounds when using a body harness. (5) The maximum elongation and deceleration distance shall be recorded during the force test. (e) Deceleration Device Tests. (1) General. The device shall be evaluated or tested under the environmental conditions, (such as rain, ice, grease, dirt, type of safety line, etc.), for which the device is designed. (2) Rope-grab-type deceleration devices. (A) Devices shall be moved on a safety line 1,000 times over the same length of line a distance of not less than one foot, and the mechanism shall lock each time. (B) Unless the device is permanently marked to indicate the type(s) of safety line which must be used, several types (different diameters and different materials) of safety lines shall be used to test the device. (3) Other self-activating-type deceleration devices. The locking mechanisms of other self-activating-type deceleration devices designed for more than one arrest shall lock each of 1,000 times as they would in normal service. III. Non-Mandatory Guidelines for Personal Fall Arrest Systems. The following information constitutes additional guidelines for use in complying with requirements for a personal fall arrest system. (a) Selection and Use Considerations. The kind of personal fall arrest system selected should match the particular work situation, and any possible free fall distance should be kept to a minimum. Consideration should be given to the particular work environment. For example, the presence of acids, dirt, moisture, oil, grease, etc., and their effect on the system should be evaluated. Hot or cold environments may also have an adverse affect on the system. Wire rope should not be used where an electrical hazard is anticipated. As required by the standard, the employer must plan to have means available to promptly rescue an employee should a fall occur, since the suspended employee may not be able to reach a work level independently. Where lanyards, connectors, and safety lines are subject to damage by work operations such as welding, chemical cleaning, and sandblasting, the component should be protected or other securing systems should be used. The employer should fully evaluate the work conditions and environment (including seasonal weather changes) before selecting the appropriate personal fall protection system. Once in use, the system's effectiveness should be monitored. In some cases, a program for cleaning and maintenance of the system may be necessary. (b) Testing Considerations. Before purchasing or putting into use a personal fall arrest system, an employer should obtain from the supplier information about the system based on its performance during testing so that the employer can know if the system meets this standard. Testing should be done using recognized test methods. Section II of this Appendix C contains test methods recognized for evaluating the performance of fall arrest systems. Not all systems may need to be individually tested; the performance of some systems may be based on data and calculations derived from testing of similar systems, provided that enough information is available to demonstrate similarity of function and design. (c) Component Compatibility Considerations. Ideally, a personal fall arrest system is designed, tested, and supplied as a complete system. However, it is common practice for lanyards, connectors, safety lines, deceleration devices, and body harnesses to be interchanged since some components wear out before others. The employer and employee should realize that not all components are interchangeable. For instance, a lanyard should not be connected between a body harness and a deceleration device of the self-retracting type since this can result in additional free fall for which the system was not designed. Any substitution or change to a personal fall arrest system should be fully evaluated or tested by a qualified person to determine that it meets the standard, before the modified system is put in use. (d) Employee Training Considerations. Thorough employee training in the selection and use of personal fall arrest systems is imperative. As stated in the standard, before the equipment is used, employees must be trained in the safe use of the system. This should include the following: Application limits; proper anchoring and tie-off techniques; estimation of free fall distance, including determination of deceleration distance, and total fall distance to prevent striking a lower level; methods of use; and inspection and storage of the system. Careless or improper use of the equipment can result in serious injury or death. Employers and employees should become familiar with the material in this appendix, as well as manufacturer's recommendations, before a system is used. Of uppermost importance is the reduction in strength caused by certain tie-offs (such as using knots, tying around sharp edges, etc.) and maximum permitted free fall distance. Also, to be stressed are the importance of inspections prior to use, the limitations of the equipment, and unique conditions at the worksite which may be important in determining the type of system to use. (e) Instruction Considerations. Employers should obtain comprehensive instructions from the supplier as to the system's proper use and application, including, where applicable: (1) The force measured during the sample force test; (2) The maximum elongation measured for lanyards during the force test; (3) The deceleration distance measured for deceleration devices during the force test; (4) Caution statements on critical use limitations; (5) Application limits; (6) Proper hook-up, anchoring and tie-off techniques, including the proper dee-ring or other attachment point to use on the body harness for fall arrest; (7) Proper climbing techniques; (8) Methods of inspection, use, cleaning, and storage; and (9) Specific safety lines which may be used. This information should be provided to employees during training. (f) Inspection Considerations. As stated in the standard (Section I, paragraph (f)), personal fall arrest systems must be regularly inspected. Any component with any significant defect, such as cuts, tears, abrasions, mold, or undue stretching; alterations or additions which might affect its efficiency; damage due to deterioration; contact with fire, acids, or other corrosives; distorted hooks or faulty hook springs; tongues unfitted to the shoulder of buckles; loose or damaged mountings; non-functioning parts; or wearing or internal deterioration in the ropes must be withdrawn from service immediately, and should be tagged or marked as unusable, or destroyed. (g) Rescue Considerations. As required by the standard (Section I, subparagraph (e)(8)), when personal fall arrest systems are used, the employer must assure that employees can be promptly rescued or can rescue themselves should a fall occur. The availability of rescue personnel, ladders or other rescue equipment should be evaluated. In some situations, equipment which allows employees to rescue themselves after the fall has been arrested may be desirable, such as devices which have descent capability. (h) Tie-off Considerations. (1) One of the most important aspects of personal fall protection systems is fully planning the system before it is put into use. Probably the most overlooked component is planning for suitable anchorage points. Such planning should ideally be done before the structure or building is constructed so that anchorage points can be incorporated during construction for use later for window cleaning or other building maintenance. If properly planned, these anchorage points may be used during construction, as well as afterwards. (2) Employers and employees should at all times be aware that the strength of a personal fall arrest system is based on its being attached to an anchoring system which does not significantly reduce the strength of the system (such as properly dimensioned eye- bolt/snap-hook anchorage). Therefore, if a means of attachment is used that will reduce the strength of the system, that component should be replaced by a stronger one, but one that will also maintain the appropriate maximum arrest force characteristics. (3) Tie-off using a knot in a rope lanyard or safety line (at any location) can reduce the safety line or lanyard strength by 50 percent or more. Therefore, a stronger lanyard or safety line should be used to compensate for the weakening effect of the knot, or the lanyard length should be reduced (or the tie-off location raised) to minimize free fall distance, or the lanyard or safety line should be replaced by one which has an appropriately incorporated connector to eliminate the need for a knot. (4) Tie-off a rope lanyard or safety line around an "H" or "I" beam or similar support can reduce its strength as much as 70 percent due to the cutting action of the beam edges. Therefore, use should be made of a webbing lanyard or wire core safety lines around the beam; or the lanyard or safety line should be protected from the edge; or free fall distance should be greatly minimized. (5) Tie-off where the line passes over or around rough or sharp surfaces reduces strength drastically. Such a tie-off should be avoided or an alternative tie-off rigging should be used. Such alternatives may include use of a snaphook/dee ring connection, wire rope tie-off, an effective padding of the surfaces, or an abrasion-resistance strap around or over the problem surface. (6) Horizontal safety lines may, depending on their geometry and angle of sag, be subjected to greater loads than the impact load imposed by an attached component. When the angle of horizontal safety line sag is less than 30 degrees, the impact force imparted to the safety line by an attached lanyard is greatly amplified. For example, with a sag angle of 15 degrees, the force amplification is about 2:1 and at 5 degrees sag, it is about 6:1. Depending on the angle of sag, and the line's elasticity, the strength of the horizontal safety line and the anchorages to which it is attached should be increased a number of times over that of the lanyard. Extreme care should be taken in considering a horizontal safety line for multiple tie-offs. The reason for this is that in multiple tie-offs to a horizontal safety line, if one employee falls, the movement of the falling employee and the horizontal safety line during arrest of the fall may cause other employees to also fall. Horizontal safety line and anchorage strength should be increased for each additional employee to be tied-off. For these and other reasons, the design of systems using horizontal safety lines must only be done by qualified persons. Testing of installed safety lines and anchors prior to use is recommended. (7) The strength of an eve-bolt is rated along the axis of the bolt and its strength is greatly reduced if the force is applied at an angle to this axis (in the direction of shear). Also, care should be exercised in selecting the proper diameter of the eye to avoid accidental disengagement of snap-hooks not designed to be compatible for the connection. (8) Due to the significant reduction in the strength of the safety line/lanyard (in some cases, as much as a 70 percent reduction), the sliding hitch knot should not be used for safety line/lanyard connections except in emergency situations where no other available system is practical. The "one-and-one" sliding hitch knot should never be used because it is unreliable in stopping a fall. The "two-and-two" or "three-and-three" knot (preferable), may be used in emergency situations; however, care should be taken to limit free fall distance to a minimum because of reduced safety line/lanyard strength. (i) Vertical Safety Line Considerations. As required by the standard, each employee must have a separate safety line when the safety line is vertical. The reason for this is that in multiple tie-offs to a single safety line, if one employee falls, the movement of the safety line during the arrest of the fall may pull other employees' lanyards, causing them to fall as well. (j) Free Fall Considerations. The employer and employee should at all times be aware that a system's maximum arresting force is evaluated under normal use conditions established by the manufacturer, and in no case using a free fall distance in excess of six feet. A few extra feet of free fall can significantly increase the arresting force on the employee, possibly to the point of causing injury. Because of this, the free fall distance should be kept at a minimum, and, as required by the standard, in no case greater than six feet. To help assure this, the tie-off attachment point to the safety line or anchor should be located at or above the connection point of the fall arrest equipment to the body harness. (Since otherwise additional free fall distance is added to the length of the connecting means (i.e. lanyard)). Attaching to the working surface will often result in a free fall greater than six feet. For instance, if a six foot lanyard is used, the total free fall distance will be the distance from the working level to the body harness attachment point plus the six feet of lanyard length. Another important consideration is that the arresting force which the fall system must withstand also goes up with greater distance of free fall, possibly exceeding the strength of the system. (k) Elongation and Deceleration Distance Considerations. Other factors involved in a proper tie-off are elongation and deceleration distance. During the arresting of a fall, a lanyard will experience a length of stretching or elongation, whereas activation of a deceleration device will result in a certain stopping distance. These distances should be available with the lanyard or device's instructions and must be added to the free fall distance to arrive at the total fall distance before an employee is fully stopped. The additional stopping distance may be very significant if the lanyard or deceleration device is attached near or at the end of a long safety line, which may itself add considerable distance due to its own elongation. As required by the standard, sufficient distance to allow for all of these factors must also be maintained between the employee and obstructions below, to prevent an injury due to impact before the system fully arrests the fall. In addition, a minimum of 12 feet of safety line should be allowed below the securing point of a rope grab type deceleration device, and the end terminated to prevent the device from sliding off the safety line should extend to the ground or the next working level below. These measures are suggested to prevent the worker from inadvertently moving past the end of the safety line and having the rope grab become disengaged from the safety line. (l ) Obstruction Considerations. The location of the tie-off should also consider the hazard of obstructions in the potential fall path of the employee. Tie-offs which minimize the possibilities of exaggerated swinging should be considered. (m) Other Considerations. Because of the design of some personal fall arrest systems, additional considerations may be required for proper tie-off. For example, heavy deceleration devices of the self-retracting type should be secured overhead in order to avoid the weight of the device having to be supported by the employee. Also, if self-retracting equipment is connected to a horizontal safety line, the sag in the safety line should be minimized to prevent the device from sliding down the safety line to a position which creates a swing hazard during fall arrest. In all cases, manufacturer's instructions should be followed. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code; and section 18943(c), Health and Safety Code.

A basic requirement of Type T equipment is that the working platform is suspended by at least two wire ropes. Failure of one wire rope would not permit the working platform to fall to the ground, but would upset its normal position. The employer shall require employees working on Type T equipment to wear a safety belt or body harness as required by paragraph (e) of this appendix. Type T powered platforms may be either roof-lowered or self-powered. (Title 24. Part 2. Section 2-8511(d)3.) (D) The requirements of this section apply to powered platforms with winding drum type hoisting machines.

This is not intended to exclude the application of other sections of Title 8, including, but not necessarily limited to, sections 1230(a), 1512, 1524, 3203, 3363, 3400, 3439, 3457, 6251, 6512, 6969, 6975, 8420 and 8602(e). This section applies to all outdoor places of employment. Note No. 1: The measures required here may be integrated into the employer's Injury and Illness Program required by section 3203. Note No. 2:This standard is enforceable by the Division of Occupational Safety and Health pursuant to Labor Code sections 6308 and 6317 and any other statutes conferring enforcement powers upon the Division. It is a violation of Labor Code sections 6310, 6311, and 6312 to discharge or discriminate in any other manner against employees for exercising their rights under this or any other provision offering occupational safety and health protection to employees. (b) Definitions. "Acclimatization" means temporary adaptation of the body to work in the heat that occurs gradually when a person is exposed to it. Acclimatization peaks in most people within four to fourteen days of regular work for at least two hours per day in the heat. "Heat Illness" means a serious medical condition resulting from the body's inability to cope with a particular heat load, and includes heat cramps, heat exhaustion, heat syncope and heat stroke. "Environmental risk factors for heat illness" means working conditions that create the possibility that heat illness could occur, including air temperature, relative humidity, radiant heat from the sun and other sources, conductive heat sources such as the ground, air movement, workload severity and duration, protective clothing and personal protective equipment worn by employees. "Personal risk factors for heat illness" means factors such as an individual's age, degree of acclimatization, health, water consumption, alcohol consumption, caffeine consumption, and use of prescription medications that affect the body's water retention or other physiological responses to heat. "Preventative recovery period" means a period of time to recover from the heat in order to prevent heat illness. "Shade" means blockage of direct sunlight. Canopies, umbrellas and other temporary structures or devices may be used to provide shade. One indicator that blockage is sufficient is when objects do not cast a shadow in the area of blocked sunlight. Shade is not adequate when heat in the area of shade defeats the purpose of shade, which is to allow the body to cool. For example, a car sitting in the sun does not provide acceptable shade to a person inside it, unless the car is running with air conditioning. (c) Provision of water. Employees shall have access to potable drinking water meeting the requirements of Sections 1524, 3363, and 3457, as applicable. Where it is not plumbed or otherwise continuously supplied, it shall be provided in sufficient quantity at the beginning of the work shift to provide one quart per employee per hour for drinking for the entire shift. Employers may begin the shift with smaller quantities of water if they have effective procedures for replenishment during the shift as needed to allow employees to drink one quart or more per hour. The frequent drinking of water, as described in (e), shall be encouraged. (d) Access to shade. Employees suffering from heat illness or believing a preventative recovery period is needed, shall be provided access to an area with shade that is either open to the air or provided with ventilation or cooling for a period of no less than five minutes. Such access to shade shall be permitted at all times. Except for employers in the agricultural industry, cooling measures other than shade (e.g., use of misting machines) may be provided in lieu of shade if the employer can demonstrate that these measures are at least as effective as shade in allowing employees to cool. (e) Training. (1) Employee training. Training in the following topics shall be provided to all supervisory and non-supervisory employees. (A) The environmental and personal risk factors for heat illness; (B) The employer's procedures for complying with the requirements of this standard; (C) The importance of frequent consumption of small quantities of water, up to 4 cups per hour, when the work environment is hot and employees are likely to be sweating more than usual in the performance of their duties; (D) The importance of acclimatization; (E) The different types of heat illness and the common signs and symptoms of heat illness; (F) The importance to employees of immediately reporting to the employer, directly or through the employee's supervisor, symptoms or signs of heat illness in themselves, or in co-workers; (G) The employer's procedures for responding to symptoms of possible heat illness, including how emergency medical services will be provided should they become necessary; (H) The employer's procedures for contacting emergency medical services, and if necessary, for transporting employees to a point where they can be reached by an emergency medical service provider; (I) The employer's procedures for ensuring that, in the event of an emergency, clear and precise directions to the work site can and will be provided as needed to emergency responders. (2) Supervisor training. Prior to assignment to supervision of employees working in the heat, training on the following topics shall be provided: (A) The information required to be provided by section (e)(1) above. (B) The procedures the supervisor is to follow to implement the applicable provisions in this section. (C) The procedures the supervisor is to follow when an employee exhibits symptoms consistent with possible heat illness, including emergency response procedures. (3) The employer's procedures required by subsections (e)(1)(B), (G), (H), and (I) shall be in writing and shall be made available to employees and to representatives of the Division upon request. Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. s 3400. Medical Services and First Aid. (a) Employer shall ensure the ready availability of medical personnel for advice and consultation on matters of industrial health or injury. (b) In the absence of an infirmary, clinic, or hospital, in near proximity to the workplace, which is used for the treatment of all injured employees, a person or persons shall be adequately trained to render first aid. Training shall be equal to that of the American Red Cross or the Mining Enforcement and Safety Administration. (c) There shall be adequate first-aid materials, approved by the consulting physician, readily available for workmen on every job. Such materials shall be kept in a sanitary and usable condition. A frequent inspection shall be made of all first-aid materials, which shall be replenished as necessary. (d) Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use. (e) Stretchers and blankets, or other adequate warm covering, may be required by the Division, unless ambulance service is available within 30 minutes under normal conditions. (f) At isolated locations, provisions must be made in advance for prompt medical attention in case of serious injuries.
