eksplosionssikker / brandsikker, eftersom der er tale om en gas detektor. Men ellers har jeg også set egensikker anvendt som oversættelse.

"Intrinsically safe equipment is defined as "equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most easily ignited concentration." (ISA-RP12.6) This is achieved by limiting the amount of power available to the electrical equipment in the hazardous area to a level below that which will ignite the gases."

Der henvises til en standard som minder om det europæiske ATEX-direktiv.
