Intrinsically Safe Equipment refers to devices designed to operate safely in hazardous environments by preventing the possibility of ignition due to electrical sparks or heat. These devices limit electrical and thermal energy to levels incapable of causing combustion in flammable atmospheres, such as those found in oil and gas, mining, and chemical industries. Intrinsic safety (IS) is a certification standard ensuring compliance with industry regulations, such as UL, ATEX, or IECEx, making the equipment suitable for explosive or hazardous zones.
