(4) At any location where conditions or operations are such that there is a probability of flammable liquid or gas being released to the atmosphere in quantities to create a hazard to employees should it become ignited.
(b) When an internal combustion engine is being operated within the hazardous areas as described in paragraphs (1), (2), (3), or (4) of subsection (a) of this section and there is a probability of flammable liquid or gas being released to the atmosphere in quantities to create a hazard to employees should it become ignited, the following precautions shall be taken to prevent the discharge of flame or sparks from the exhaust pipe:
(1) In area described in paragraph (1) of subsection (a) of this section, the exhaust system shall be provided with a water injection system or other effective device.
(2) In areas described in paragraphs (2), (3), or (4) of subsection (a) of this section, shutting down the engine will be accepted in lieu of providing the exhaust system with a water injection system or other effective device.
(c) Exhaust systems shall be maintained in good operating condition.
(d) Combustible material shall be prevented from contacting the hot surfaces of internal combustion engines and their exhaust systems or insulation shall be provided to prevent them from becoming ignited.
(e) Cylinder cocks of internal combustion engines shall not be opened when a flame or spark may be discharged into the atmosphere where there may be an accumulation of flammable gas.
(f) All electrical accessories of an internal combustion engine, including magnetos, distributors, coils, batteries, generators, starting motors, spark plugs, ignition cables and other miscellaneous wiring and switches shall be installed and maintained in a manner which will prevent arcing and sparking.
(g) Ignition systems, electrical accessories and equipment shall not be manipulated in a manner to create an arc or spark in open air where there may be an accumulation of flammable gas.
(h) Electrical storage batteries shall be provided with suitable covers to prevent contact with the battery terminals.
