Intrinsic safety Wikipedia

Not to be confused with inherent safety, the more general industrial technique of minimizing the danger of a process.. Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic

Are Lithium Ion Cells Intrinsically Safe?

Permissible equipment may be evaluated as intrinsically safe (IS). The 30 CFR 18.2 interprets IS as incapable of releasing enough electrical or thermal energy under normal or abnormal conditions to cause ignition of CH 4 or natural gas and air of the most easily ignitable composition.

Are drones intrinsically safe? Flyability

The question of whether drones are intrinsically safe is one of the first that comes to the mind of Oil & Gas and Chemical professionals. So far the answer is no. But, does that prevent drones from being used in these industries? Here is a complete answer to that complex question.
