  • How does Intrinsic Safety work? | Abhisam

    Introduction. Intrinsic Safety is a concept that came out of the mining industry in the early 19th century. At that time, a lot of mining accidents used to happen, many of which were traced to sparks that were generated by electrical circuits, that were used in mine lighting, signalling equipment and the like.

  • What is Intrinsic Safety? - esi-tec.com

    This is the basic principle of intrinsic safety. As the name implies, intrinsic safety refers to equipment and wiring that's inherently safe. In other words, an intrinsically safe system is one with energy levels so low they cannot cause an explosion. Intrinsic safety is a concept that was born in the mining industry in the early 19th century.
