Typically, reaching IIB is sufficient for gases, but for hydrogen, acetylene, and carbon disulfide, a higher level of IIC is required. For dust explosion protection, just achieve the corresponding gas explosion-proof level and the highest dust grade. Areas such as oil refineries, chemical plants, grain silos, and mining facilities may contain flammable gases, combustible dust, or ignitable. Explosion-proof (Ex d) contains an explosion. Intrinsically safe (Ex i) prevents ignition entirely by limiting energy. Do hazardous area enclosures need special cable glands? Yes. Cable glands must match the enclosure type (Ex d, Ex e, Ex t, etc. Common protection methods include: These principles are. Explosionproof enclosures are used as classified enclosures, pull boxes, or control panels in rigid conduit systems and with metal clad cable rated for hazardous locations.
