WHAT IS INTRINSIC SAFETY AND EXPLOSION PROOF? ... Therefore, Intrinsically Safe means that an apparatus, such as a temperature transmitter is not capable of causing an explosion. Explosion Proof means that should an explosion occur, it will be contained within an enclosure.

What does intrinsically safe mean?

ISA-RP12-6 defines intrinsically safe equipment as "equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most easily ignited concentration."

What is the difference between ATEX and intrinsically safe?

Intrinsic safety is a protection standard employed in potentially explosive atmospheres. ... ATEX is a European standard developed in part by the International Electrotechnical Commission (IEC). IEC is responsible for setting international standards for electrical technology.
