Belt Shifter. A device for mechanically shifting belts.
Conveyor. A device designed exclusively for transporting bulk materials, packages or objects in a predetermined path and having fixed or selective points of loading or discharge.
Enclosed. The moving parts are so guarded that physical contact by parts of the body is precluded. This does not prohibit the use of hinged, sliding, or otherwise removable doors or sections to permit inspection or lubrication.
Flywheel sometimes referred to as a balance wheel or flywheel pulley means a heavy wheel which by its inertia provides uniform energy of machinery by resisting sudden changes of speed.
Guarded. Shielded, fenced, enclosed or otherwise protected according to these orders, by means of suitable enclosure guards, covers or casing guards, trough or "U" guards, shield guards, standard railings or by the nature of the location where permitted in these orders, so as to remove the hazard of accidental contact.
Guarded by Location. The moving parts are so located by their remoteness from floor, platform, walkway, or other working level, or by their location with reference to frame, foundation or structure as to remove the likelihood of accidental contact.
Machine. The driven unit as distinguished from the driving unit which is defined as a prime mover.
Machine Parts. All moving parts of the machine, except those forming part of the point of operation.
Momentary Contact Device. A device which requires constant pressure by the operator to operate the machine.
Nip-point. That location along the inrunning side(s) of rotating part(s) which permits a part of the body to be caught between two moving part(s) or between a moving part and a stationary object.
Power Drive, Portable. A device used to provide rotary motion which can be used to grip and rotate a pipe or die head to thread, cut and ream.
Prime Mover. An engine or motor whose main function is to drive or operate other mechanical equipment.
Sheaves. Grooved pulleys, unless used as flywheels.
Tail Rod. The extension of piston rod passing through a stuffing box in the outside head of an engine cylinder, compressor cylinder or pump cylinder.

s 3942. Type of Guarding Required.
(a) All guards shall be appropriate for the hazards involved, secured in place, constructed of substantial material as listed in Table G-1; and have surfaces free of hazardous projections.
(b) Guards shall be provided with hinged or removable sections where it is necessary to change belts, make adjustments, or for the admission of lubricants.
s 3943. Guard Standards.
(a) If area of shield guard of wire mesh or expanded metal in a frame exceeds 6 square feet, it shall be reinforced.
(b) Trough or "U" guards shall be installed in accordance with the guidelines illustrated in Figures G-5 and G-6.
(c) An enclosure guard shall be installed so that it completely guards the moving parts.
(d) A nip-point belt and pulley guard shall be constructed so that the nip-points are not exposed to accidental contact.
(e) Horizontal overhead belt guard surfaces subject to contact with the belt shall be smooth. The guard width shall be at least 25% wider than the belt being protected. The clearance need not exceed 6 inches on each side.
(f) Guards for horizontal overhead rope and chain drives shall not be less than 6 inches wider than the drive on each side. Where employees pass under overhead rope and chain drives a shallow trough or other effective means of sufficient strength to carry the weight of the broken chain shall be provided.
Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code.
s 3944. Guard Clearances.
(a) Where a guard or enclosure is within 2 inches of moving parts, openings through the guard shall be of such size as will preclude the passage of any object one-half inch in diameter.
(b) Where a guard or enclosure is within 4 inches of moving parts, openings through the guard shall be of such size as will preclude the passage of any object greater than one-half inch in diameter.
(c) Where a guard is located between 4 inches and 15 inches from moving parts, the maximum opening shall be of such size as will preclude the passage of any object greater than 2 inches in diameter. Where a slatted guard is used, the width of the opening shall be not greater than 1-inch.
(d) Standard railing guards shall be placed not less than 15 inches nor more than 20 inches from any moving parts provided; however, that where clearances from other moving parts are less than 15 inches, such parts shall be guarded as required elsewhere in these orders.
(e) The use of nylon mesh or materials of equivalent strength with holes not exceeding 1/2-inch to modify an existing substandard fan guard is acceptable, provided the combination of the two provides adequate protection and the mesh cannot be pushed into the danger zone during normal use.
