What Does it Mean for Equipment to be Intrinsically Safe?
A piece of equipment that is designated as intrinsically safe has been designed to operate in a potentially explosive environment. In the simplest terms, under any operating conditions, the equipment and wiring is not capable of releasing sufficient electrical or thermal energy for ignition.

What types of environments are potentially explosive? We often think of flammable gasses or fuels, but dust and fine powder can also create potentially explosive environments. Common work environments for which intrinsically safe devices are necessary include on oil rigs, in refineries, in mining operations, pharmaceutical manufacturing, and farming...
