G3/4 Circular Explosion Proof Junction Box for Dispensing Areas

Plenty of commercial facilities have areas where lighting fixtures can come into contact with hazardous materials. These can be flammable, combustible, or ignitable materials, gases, or vapors. These areas can be at risk of fire or even explosion if the lighting fixtures can't withstand the abnormal conditions.

Hazardous location lighting refers to fixtures that you can safely use in an area where it's likely that fire might start. According to the National Electrical Code, hazardous locations are those areas where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.

Explosion proof lighting refers to lighting fixtures that are able to contain sparks that could potentially the flammable and explosive gases in the atmosphere. Therefore, explosion proof lighting does not refer to lighting equipment that are resistant to explosions but rather, the capacity to prevent external explosions from occurring in a hazardous location.

Presence of Flammable Liquids and Gases. Wherever flammable gases and liquids are present, the location may be identified as a hazardous one because such compounds can cause an explosion or catch fire. Gas and liquids have to achieve a critical concentration before it becomes dangerous. However, once they do, that's when a potential disaster can occur.

The shell is formed by one-time die-casting of high-strength alloy aluminum, and the surface is cleaned by high-speed shot blasting and then sprayed with high-voltage electrostatic spraying. It can also be made of Carbon Steel or Stainless steel.
