Explosion proof lighting refers to lighting fixtures that are able to contain sparks that could potentially ignite 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.
An explosion proof lighting fixture is typically encased in a thick frame that is usually made from sturdy material like steel or aluminum. Ex proof lighting fixtures are also equipped with extremely durable lenses that can withstand harsh working conditions and prevent cracks, which can result in leaks.
There are some common misconceptions about explosion-proof lights that are worth addressing. For example, many people assume that these lights work by blocking out all gases or vapors so that they can never come in contact with live electrical power, even if the light were to break. That is typically NOT the case. Explosion-proof lights do not have to be “airtight” to perform their function. Many explosion-proof lights will allow gases into the light itself. The important part of their construction is to prevent any explosion caused by those gases from escaping to harm the worker or further ignite gases in the work area. So before submerging your explosion-proof light to clean it off, it’s best to check with the manufacturer to see whether this is acceptable.
We highly encourage you to incorporate the use of explosion proof lights especially if your business operates in a confined space at a hazardous location. Moreover, the low visibility and mobility of confined spaces, such as oil rigs and petrochemical plants, makes it necessary to install explosion proof lights in order to carry out maintenance and inspection.
