Mar 25, 2006 · What does "intrinsically safe" mean to you? It is NOT the same as "fail safe". Whole industries like oil, gas, mining etc., have specific definitions of what intrinsically safe means to them, for example: that any fault will not cause sparks which can ignite flammable vapour or dust that may be present, or that it will not cause toxic fumes/smoke under fault conditions, or start a fire (e.g

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. At that time a lot of mining accidents were traced to sparks that were generated by electrical circuits used in mine lighting and signalling
