No worker shall enter a workplace where a flammable or explosive substance is present in the atmosphere at a level that is more than 10% of the lower explosive limit of that substance.
- Only if in a life-threatening emergency exposure of emergency response workers is permitted above 10% of the LEL provided that only the minimum number of those qualified and properly trained and equipped workers necessary to correct the unsafe condition are exposed to the hazard and every possible effort is made to control the hazard while this is being done.
- Quantities of flammable substances stored in non-hazardous locations will be limited to ensure that there is not sufficient quantity to produce an explosive atmosphere should there be a release. Flammable substances will not be stored or used at a work area (that is considered not a hazardous location) within 30 meters of an underground shaft or stored or used within the immediate vicinity of the air intake of a ventilation supply system, internal combustion engine or the fire box of a fired heater or furnace/heating system.
- When portable flare stacks are used these must be located a minimum of 25 meters from the hazardous location.
- Good housekeeping and preventative maintenance on all equipment shall be maintained to prevent fire hazards from occurring
- Smoking must be confined to areas specifically designated by CorSafety. management. Smoking is not permitted while around any active/functioning hydrocarbon cleanup/vacuuming equipment, around compressed gas cylinder storage locations or at any CorSafety. or client designated "No Smoking" areas.
- Oily/greasy rags, paper waste and other flammable trash will be removed and disposed of in covered metal containers or appropriately marked safety cans, or in over-pack spill containers, whenever these sources are generated, for the prevention of spontaneous combustion.
- Matches or cigarette lighters should not be taken into any area where an explosive atmosphere may be present.
