In an environment with explosive hazardous location stipulated by the US ANSI National Standard, the location with combustible gas, vaporized or liquid combustible material.

According to the classification of organic flammable and explosive gases , vaporized and evaporated flammable and explosive liquids, it can be divided into 10 categories: alkane, alkene, alkyne, ether, benzene, alcohol, aldehyde, ketone, ester, and polymer. 

These products are important raw materials for the national economy and people's livelihood. These products are produced in the CLASS I environment conditions production area. 

CESP  Explosion-Proof LED Light can be used for the follow Lcation of CLASS I
