Class II Division 2 Groups F and G Explosion Proof Lights These fully-sealed durable explosion proof LED lights provide lighting within potentially dangerous spaces where ignitable vapors and gasses are present.

Atmosphere containing a flammable gas a flammable liquid produced vapor or a combustible liquid produced vapor mixed with air that may burn or explode having either a MESG Maximum Experimental Safe Gap 1 value less than or equal to 045 mm or a MIC Minimum Igniting. The operating cost is 050 per mile and the base mileage rate ie revenue is061 per mile. Their group ratings designate use in locations with specific types of gas vapor or dust.

Employers may use the zone classification system as an alternative to the division classification system for electric and electronic equipment and wiring for all voltage in Class I Zone 0 Zone 1 and Zone 2 hazardous classified locations where fire or explosion hazards may exist due to flammable gases vapors or. For definitions of these locations see 1926. They can be manufactured anywhere in the world but they need to be approved only by North American certifying agencies for use in Canada and the US.

1 - 1 of 1 Results. The fact that there is some combustible dust present does not mean a Class II hazardous location exists. Note that the dust must be present in sufficient quantities for a fire or explosion hazard to exist.
