Būtībā droša un nedroša jēdzieni

Pēc būtības drošs veids, saukta arī par pēc būtības drošu kategoriju, tiek uzskatīts par drošāko starp dažādām sprādziendrošu klasifikācijām.

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.
