FAQ- HAZARDOUS AREA CLASSIFICATION-IS (HAC)
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.

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.
METHODOLOGY FOR HAZARDOUS AREA CLASSIFICATION (IEC)
The purpose of the Hazardous Area Classification study is to determine the extent of the hazardous areas around equipment handling or storing flammable fluids, combustible fluids and combustible dusts, both liquid and vapors in terms of Zone 0/20, Zone 1/21, Zone 2/22 The aim of hazardous area classification is to avoid ignition of those releases that may occur from time to time in the operation of facilities handling flammable liquids and vapors. The approach is to reduce to an acceptable minimum level the probability of coincidence of a flammable atmosphere and an electrical or other source of ignition occurring. In Hazardous Area Classification the extent of the hazardous areas around equipment handling or storing flammable fluids, both liquid and vapors is determined in terms of Zone 0, Zone 1, and Zone 2. The hazardous area classification around the equipment handling flammable/explosive dust is determined in terms of Zone 20, Zone 21, and Zone 22.
