Explosion Proof Light Fittings
To meet the criteria for the explosion-proof rating, an enclosure must be able to contain any explosion originating within its housing and prevent sparks from within its housing from igniting vapors, gases, dust, or fibers in the air surrounding it. Therefore, explosion proof, when referring to electrical enclosures, does not mean that it is able to withstand an exterior explosion. Instead, it is the enclosures ability to prevent an internal spark or explosion from causing a much larger blast.
The equipment must meet the temperature requirements of the specific application in which it is to be installed. This means that the operating temperature of the motor (and its enclosure) or another component cannot be greater than the lowest ignition/combustion temperature of the gases or dust in the atmosphere where the component is to be installed.
Some refineries and processing facilities operate in cooler environments. Because of the often cooler ambient temperatures, heat is often required in these applications. However, typical open coil heaters cannot be used in hazardous areas due to the explosion hazard. For these applications, explosion proof fin tube heaters must be utilized. Explosion proof heaters incorporate fin tube heating elements and enclosed electrical connections to meet code and reduce surface temperatures.
