ከውስጥ ደህንነቱ የተጠበቀ እና ውስጣዊ ያልሆነ ደህንነት ጽንሰ-ሀሳቦች

ውስጣዊ ደህንነቱ የተጠበቀ ዓይነት, እንዲሁም ውስጣዊ ደህንነቱ የተጠበቀ ምድብ ተብሎም ይጠራል, ከተለያዩ ፍንዳታ-ማስረጃ ምደባዎች መካከል በጣም አስተማማኝ ነው ተብሎ ይታሰባል።.

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.
