Why might electrical codes require specific conduit types in hazardous locations?

In hazardous locations, specific conduit types are required primarily to enhance safety against electrical explosions or fires. These areas often contain flammable gases, vapors, or dust that could ignite in the presence of an electrical arc or spark. The use of designated conduit types—such as explosion-proof or intrinsically safe conduits—helps to contain any potential sparks and prevents the external environment from triggering an ignition.

These conduit systems are engineered to withstand the harsh conditions present in these environments, providing an added layer of protection against accidental ignition. By using the appropriate materials and designs, the electrical system remains compliant with safety regulations and reduces the risk of catastrophic events, thereby protecting both personnel and property. Other considerations, such as installation ease, cost, or aesthetics, while relevant in general construction scenarios, do not hold the same critical importance in hazardous locations where safety is paramount.
