These Class I and II fixtures illuminate Division 1 hazardous locations where flammable gases or vapors and/or combustible dusts are normally present. Their group ratings designate use in locations with specific types of gas, vapor, or dust. Also called explosion-proof fixtures, they contain explosions that may trigger within the fixture and prevent arcs or sparks within the fixture from igniting gases, vapors, or dusts on or near the fixture.Flammable gases and vapors are Class I hazards commonly found in petroleum refineries, fuel dispensaries, sewage treatment plants, and processes using chemicals, paints, coatings, or sealants. Combustible dusts are Class II hazards commonly found in pharmaceutical factories, coal-handling plants, grain elevators, and plants processing flour, feed, or powder.
