Intrinsic Safety Explained
An Intrinsically Safe Barrier is a device which limits the power (energy) which can be delivered from a safe area into a hazardous zone. Explosions are prevented; not just contained in explosion-proof conduit and housings. Not only is electrical energy (voltage and current) held within safe limits, but total energy is also contained, eliminating the possibility of an explosion due to excessive heat. Use of barriers and a total intrinsically safe design philosophy offers considerable advantages from cost and safety standpoints.
