In the last edition of 20/20 Insights we covered the concept of intrinsically safe (IS) systems and how their design limits the release of energy into a hazardous atmosphere to prevent ignition. Now we will look more closely at selecting the right combination of parts to produce a safe and reliable...

The concept of intrinsic safety in wiring recognizes that ignitable, flammable or combustible materials will be present with air, or other oxidizer, in sufficient quantity and ratio so as to represent a fire or explosion hazard. These mixtures could easily be ignited by a match or other open flame...
