Explosion Proof and Intrinsic Safety Solutions

Explosion Proof and Intrinsic Safety Solutions

Oil refineries, petrochemical processing plants and even coal mines to a certain extent operate in the presence of combustible gases and vapors. So, it’s very important for equipment, more specifically electrical and electronic equipment that operate in that atmosphere, not to cause a spark which can ignite the gases, leading to an explosion. Explosion proof/intrinsic safety are two technologies which guarantee that under no circumstances will equipment emit energy to cause an explosion.

The objective of this document is to describe how to do the mechanical and electronic design for electrical/electronic equipment deployed in a hazardous environment.  This document does not cover barriers placed in safe areas, and focuses only on  devices placed in hazardous areas.
