Intrinsic safety (IS) is a method of providing safe operation of electronic process control instrumentation in hazadous areas. IS systems keep the available electrical energy in the system low enough that ignition of the hazardous atmosphere cannot occur. No single field device or wiring is intrinsically safe by itself (except for battery-operated, self contained devices), but is intrinsically safe only when employed in a properly designed IS system.
