What does Intrinsically Safe Mean?
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. It refers to equipment and wiring that are designed to operate safely in hazardous environments where flammable gases, vapors, or dusts are present. The idea behind intrinsic safety is preventing ignition by ensuring that the electrical energy in a circuit is kept below the level that could cause a spark or excessive heat. To prevent explosion, you need intrinsically safe equipment in hazardous areas.
