What Is Explosion Proof Lighting And How to Choose?

(Last Updated On: )

Explosion-proof lighting is a crucial safety feature for environments with a risk of explosion, such as in the oil and gas, mining, or chemical processing industries. These environments have a high concentration of flammable gases, vapors, or dust and can be extremely dangerous if proper safety measures are not in place.

Hazardous environments in specific industrial settings require special precautions to ensure worker safety. High-protection lighting fixtures, also known as dangerous location lights or explosion-proof lights, are necessary to protect against water, corrosion, impact, and explosion. These fixtures are made of durable materials and must meet specific safety standards and certifications.

Explosion-proof lighting fixtures are designed to be used in these hazardous environments and are built to withstand harsh conditions. They are made of materials resistant to corrosion and sealed to prevent dust or moisture from entering the fixture. These fixtures must meet specific certifications such as UL and ATEX to ensure they are safe to use in hazardous environments.

Is Explosion-proof light the same as vapor-tight or shatterproof light fixture?

Many people conflate explosion-proof lights with either shatter-resistant or vapor-tight fixtures when they’re different types of lights. Vapor-tight lights are sealed and gasketed to safeguard their internal elements from fumes, dust, and moisture. Shatterproof lamps are made with shatter-resistant lenses to stop the fixture from shattering on the chance of exposure to high heat.

While explosion-proof light fixtures are shatterproof and vapor-tight, they also contain design elements that make them specially equipped for use in hazardous environments. As mentioned, explosion-proof lights are designed to ensure they don’t initiate an explosion when exposed to high temperatures or arcing contacts. This makes them safe for use in areas where hazardous gasses and flammable materials are present and where outbreaks are more likely to occur.

What Makes A Light Explosion Proof?

While many different styles of explosion-proof lights, all explosion-proof light fixtures are generally constructed using the same common elements. These include:

Ultra-durable casing: Explosion-proof lights have a virtually unbreakable shell to protect the internal components of the fixture and prevent sparks or flames from escaping and igniting flammable gases or dust. The enclosure is made of materials resistant to corrosion, impact, and other hazards, such as aluminum, stainless steel, or fiberglass. The lenses of explosion-proof lights are also shatterproof, often tempered glass, to withstand potential impacts and explosions.

Ignition-resistance: Explosion-proof lighting fixtures are designed to be ignition-resistant, ensuring they do not contribute to the risk of explosions or fires in hazardous environments. These fixtures are vapor-tight, meaning they have ultra-airtight seals that prevent flammable materials, such as vapors, gases, or fibers, from entering the fixture. This design ensures that the institutions function safely and seamlessly in any hazardous environment.

Thermal control mechanisms: Explosion-proof light fixtures often come equipped with thermal control mechanisms to prevent heat buildup inside the fixture. Many of these fixtures are designed with copper-free housings and double-folded aluminum fins, which help dissipate heat and avoid combustion. These thermal control mechanisms ensure that the fixture remains cool and does not contribute to the risk of fire or explosion in hazardous environments.

Ratings and zones classify Explosion Proof Lighting

Ratings are used by professionals, like engineers, architects, and electricians, to find the ideal place for the light source to be used, as well as under what conditions they will perform best. When shopping for options, look at the Certifications: Class I, Division 1, Class I, Division 2, and Zones 0, 1, and 2. Class I, Division 1, encompasses Zone 0 and Zone 1 areas, while Class I, Division 2, only qualifies for Zone 2 areas.

Zone 0 is a hazardous location where explosive gas, vapor, or liquid atmosphere is present continuously or for long periods.

Zone 1 has frequent ignitable gas, vapor, or liquid under normal operating conditions, between 10 to 1,000 hrs/year.

Zone 2 is where flammable gas, vapor, or liquid is not present or unlikely to be present during normal operating conditions, and unwanted or hazardous substances will only be present for 10 hrs/year or 0 to 0.1% of the time.

The Importance of Eplosion-proof Lights

Explosion-proof lights are vital for workers in hazardous environments with a risk of explosions or fires. These environments are typically found in industries such as oil and gas, mining, and chemical processing, where flammable gases, vapors, or dust are present. Workers can risk severe injury or even death without the appropriate lighting fixtures.

Explosion-proof lights are designed to prevent sparks or other ignition sources from causing an explosion or fire. They are made of durable materials that withstand harsh conditions, such as high temperatures, pressure, and potential impacts. These fixtures are also sealed to prevent dust or moisture from entering the institution, which can increase the risk of an explosion.

In addition to their safety features, explosion-proof lights can improve efficiency and productivity in hazardous environments. For example, adequate lighting can help workers see their work better and prevent accidents caused by inadequate lighting.

The color temperature of the light should be soft and warm, with a color temperature ranging from 2700K to 3000K. Brightness levels should be adjustable, allowing residents to control the light in the room based on their needs. Due to their warm, inviting glow, LED and incandescent lights are often used in residential environments.

Commercial Environments: In retail environments, lighting needs to be bright and consistent. The color temperature of the light should be bright and neutral, with a color temperature of around 4000K. Brightness levels should be constant throughout the space to avoid creating areas of glare or shadow. LED and fluorescent lights are often used in commercial environments due to their brightness and consistency.

Outdoor Environments: Lighting must be bright and weather-resistant in outdoor environments. The lights should withstand harsh weather conditions and provide adequate illumination for safety and security purposes. LED and metal halide lights are often used outdoors due to their brightness and weather resistance.

Regarding mounting options, lighting fixtures can be mounted on the ceiling, walls, or even on the ground, depending on the specific requirements of the environment. Therefore, choosing the correct mounting option is essential to ensure the lights are positioned most effectively and efficiently.
