For gas explosion protection, various methodologies are employed, including Flameproof (d), Increased Safety (e), Intrinsic Safety (i), Pressurized Enclosure (p), Encapsulation (m), Oil Immersion (o), Sand-Filled (q), “n” Type (nA, nR, nL, nZ, nC), and Special Protection (s).
Regarding dust explosion protection, the approaches encompass Intrinsic Safety (iaD or ibD), Enclosure Protection (tD), Encapsulation Protection (mD), and Pressurized Enclosure Protection (pD).
