Sisemiselt ohutu ja mittesisemiselt ohutu kontseptsioon

Sisemiselt ohutu tüüp, nimetatakse ka sisemiselt ohutuks kategooriaks, peetakse erinevate plahvatuskindlate klassifikatsioonide seas kõige ohutumaks.

Products classified as intrinsically safe are engineered in such a way that any electrical sparks or thermal effects generated under normal or pre-defined fault conditions do not trigger explosions in the surrounding atmosphere, which may contain flammable or explosive gases.

According to the GB3836.4 standard, intrinsically safe equipment is defined as electrical devices where all internal circuits are deemed intrinsically safe.

Non-intrinsically safe variations are typically employed in areas that do not require explosion-proof measures.
