Dec 27 2012What is the difference between explosion proof and intrinsically safe? In explosion-proof equipment the internals must be engineered to contain an internal explosion and avert a much larger detonation Intrinsically safe rating means the electronics cannot spark or create sufficient energy to ignite In both cases the equipment's surface temperature cannot meet or ignite the gas or vapor
