What is Intrinsically Safe?

Intrinsically Safe means that the system is incapable of causing an explosion or being a source of ignition in the presence of potentially explosive or combustible materials and gases.  In other words, the equipment and wiring are 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.  OSHA and MSHA have many reports of fires caused by non-intrinsically safe systems.  Preventing fire and explosions is a top priority for all industries around the world.
