Overview of Explosion Proof Emergency Lights

In environments where volatile fumes are present, OSHA and National Electrical Code regulations stipulate the installation of explosion proof lighting. This doesn’t just apply to the regular lighting, but emergency lighting as well.

Explosion proof emergency lights are guaranteed as safe and compliant by UL (Underwriters Laboratories). UL 924 is the certification that all emergency lights are tested to. Additional UL certifications are held by our explosion proof emergency lights which insures their operability in the most hazardous of locations. The following will explain the design, construction, and application of explosion proof emergency lighting fixtures.

Explosion Proof Lighting Design

Explosion proof lights incorporate two basic design criterion; which between them, make the light explosion proof:

• Sealed cases to prevent fumes reaching electrical components – Many class B fires (flammable chemical fires) are started by an electrical spark. Cases on explosion proof lighting are sealed to prevent the entry of flammable vapors. That way, any electrical spark is kept away from combustible materials.
• Reinforced cases that won’t be damaged in the case of an explosion – In the case of an explosion not caused by a spark from the light, the case of the light needs to withstand the force of the explosion, without damage; allowing the light to continue functioning. This ruggedness of design also insures that the case will not be ruptured by any casual damage, like from a fork-lift, which would ultimately cause a greater fire/explosion risk.

Explosion Proof Emergency Lights are designed for the most extreme conditions. All models are UL Listed and made in the Unite States.

Explosion Proof Emergency Light Applications

Any area where flammable volatile compounds (easily evaporating) are used or stored needs to have explosion proof lighting and emergency lighting. This includes most places where petrochemicals are used and stored, gasoline dispensing areas, propane dispensing areas, and coal or oil fired furnace rooms.

In a manufacturing facility, any areas where work is done with solvents, paints or other chemical adhesives will need explosion proof lighting. Additionally, maintenance shops and service areas for vehicles require explosion proof lighting.

Explosion proof emergency lights are popular for oil rigs and natural gas plants. In such locations, it can be important to choose higher wattage lamps. The explosion proof emergency lights that we offer come standard with 8-watt lamps but can be outfitted with up to 25-watt lamps. Both halogen and sealed beam bulbs are aviable.

Flammable Areas and Explosion Proof Emergency Lights

These same requirements exist for areas where flammable dust particles are prevalent. Wood furniture manufacturing is a perfect example of a highly flammable dust environment. Both the dust in flammable dust in the air, and the vapors in the finishing room indicate the necessity of installing explosion proof emergency lights.

Even if your current operations do not include flammable liquids, if you are using solvents, you might want to consider the investment in explosion proof emergency lights. That way, your facility is ready for working with flammable liquids, in case the need should arise.

Explosion proof emergency lights are manufactured under extremely strict quality control standards which insure their safety, reliability, and functionality. Purchasing explosion proof emergency lights at wholesale prices has never been easier or made better sense. All explosion proof emergency lights ar warrantied for three years and replacement parts are always available.

Explosion Proof Emergency Lighting

Other than being explosion proof, these lights work the same as any other emergency light. Just as with any emergency light, explosion proof emergency lights are required to run for a 90 minute minimum in the case of power loss.

There are explosion proof emergency lights manufactured for all IEC classes and zones of hazard. These ratings are based upon the flammability, volatility (how quick it evaporates) and explosive power contained within the materials. Material packaging should be labeled with an IEC code, which tells you what type of explosion proof lighting you need. You must insure that your lighting is of at least as high a level of classification and zone as the materials you are using.

The major differences between the various levels of protection required for the different classes and zones of hazard is in the sealing of the lighting unit, to prevent any possibility of vapors entering into the light enclosure. Basically, substances that are made of smaller molecules require tighter sealing against vapor entry.
