FAQ - Hazardous Area Classification (HAC) Study - NFPA
Hazardous Area Classification (HAC) is a critical safety study aimed at identifying and defining the areas around equipment that handles or stores flammable fluids, vapors, and combustible dusts where the risk of fire or explosion is present. The primary goal is to minimize the possibility of an ignition source coinciding with a flammable atmosphere, thereby reducing the risk of fire or explosion.
