Explosion-proof lighting fixtures are lights that are used in industrial environments in which flammable gases are present. The biggest difference, though, between explosion-proof lights and standard electric lights is that explosion-proof lamps are designed to eliminate the risk of an electrical spark from the fixture to ignite a gas in the area.
There are many different types available including LED explosion-proof work lamps and overhead fluorescent lamps, and they are widely used in hazardous working environments like in the mining and oil and gas industry. Each light is designed with a range of innovations that eliminate the risk of a fire or explosion. Specially-designed parts include:
- Light heat management elements
- Flame-tight seals
- Flame-tight joint
Each of these elements ensures that A) gases cannot come in contact with the electric current and B) the lamp never reaches a specific heat that would create a dangerous environment.
When Are Explosion-Proof Lamps Needed?
In general, explosion-proof lighting is required in hazardous environments that have or could have gases present in the air. Originally, these lights were fire-powered kerosene lamps that were used by miners in the late 1800s. Yet, as electricity became portable, flame-powered lamps were replaced with electric lamps.
These types of lights are used in many different instances:
- Offshore oil rig lighting
- Underground mining environments
- Gas drilling sites
- Hazardous manufacturing facilities
And when they are needed is often dictated by governmental regulatory groups. For example, in the U.S., the OHSA have mandates in place for when explosion-proof lights are needed. In the U.S., explosion-proof lights must be used in “any area that the atmosphere is determined to contain a concentration of flammable vapors that are at or above 10 percent of the lower explosive limit,“ according to the OHSA.
Typically, explosion-proof equipment must be tested as to the type of environment that it is suitable for use in. For example, the OHSA has several classes and types of devices that have been approved for use in environments with gas and vapors, dusts, and fibers. Be sure that the type of light is deemed safe for the type of flammable material that is present.
