The electrical classification term "Hazardous Location" refers to areas where flammable gases, vapors, liquids, combustible dusts, ignitable fibers or flyings are present in the atmosphere in sufficient volume to cause an explosion of fire.
Electrical equipment placed in hazardous locations must be carefully selected and applied in accordance with national and international "HazLoc" (sometimes referred to as explosion-proof) standards. These standards evaluate the threat of explosion based on quantitative and qualitative criteria such as material phase, specific gas of liquid, and likelihood of exposure.
