Safety is a major concern, especially for companies operating in hazardous environments. Therefore, safety equipment in potentially hazardous environments should always be present to stop the risk of explosions and other accidents. This is the reason why explosion-proof lighting has become an important part of industrial setups.

The purpose of this article is to provide some overview about explosion-proof lighting to help you make more informed decisions for your business.
Explosion-proof lighting refers to lighting fixtures that are capable of containing sparks that could ignite flammable and explosive gases in the atmosphere. Explosion-proof lighting therefore does not refer to lighting fixtures that are explosion resistant, but rather to the ability to prevent external explosions from occurring in hazardous locations.
These lights consist of a thick metal or steel frame with a strong lens, and the entire housing blocks internally generated sparks and prevents them from combining with combustible sources in the nearby atmosphere. This reduces the risk of accidents and improves the overall safety of workers, as well as expensive assets on the premises.

The installation of explosion-proof lighting significantly reduces the risk of explosion by preventing ignition of surrounding flammable gases and vapors. In addition, the National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), requires that all lighting used in hazardous locations be explosion-proof.
Due to the rugged design of explosion-proof lighting fixtures, the risk of explosion and fire is extremely low. This therefore also greatly increases the safety of employees working in hazardous locations.

Because explosion-proof lighting fixtures are typically made of stronger and heavier materials, they are able to withstand harsher working environments. Explosion-proof lights do not break as easily as standard lighting fixtures, making them a better choice for operating in confined spaces.
Thanks to a stronger frame and thicker tempered glass lens, explosion-proof lamps are highly resistant to vibration. This allows for greater mobility, and explosion-proof lights can be transported from one location to another by forklift or other transport machinery without being easily damaged.
Explosion-proof lighting fixtures are more portable than standard lights, which makes them ideal for businesses that need mobile lighting for operations.
Explosion-proof lightings are more energy efficient than traditional lighting fixtures. They use approximately 90% less energy than standard lighting fixtures. Explosion-proof LED lamps have a longer service life than traditional lighting fixtures. Installing explosion-proof lightings will allow you to save on operational and production costs.
In addition to the energy-saving advantages, explosion-proof LED lamps do not contain toxic and hazardous substances that are harmful to the environment, such as mercury and lead. Therefore, using explosion-proof LED lights instead of traditional lighting fixtures can also make your business environmentally friendly.

Explosion Proof Lighting plays an essential role for the safety measures that need to be put in hazardous operations. They protect one against igniting flaming materials. Consequently, lighting is a vital concept both in the oil and gas, chemical production, as well as mining industries. What is the secret of explosion-proof lighting? Get into this insight to understand better.
Explosion-proof lighting, also known as hazardous location lighting, is designed for areas where explosive gases, vapors, or flammable dust may be present. Some people believe that explosion-proof lights cannot explode. That is not how they work; they merely contain any potential ignition inside the fixture so it does not leak into the air.
Explosion-proof lighting is in the scope of safety standards and regulations published by various organizations, among them, National Electrical Code (NEC) in the United States of America. There are the following categories:
Class I: The luminaire meets locations which contain flammable gases or vapors - oil refineries, for example.
Class II: For installation in places that are rich in combustible dust, such as grain silos, and sugar refineries.
Class III: Intended for use in areas which involve either flammable fibers or flying debris - fabric mills, for instance.
Every class is further subdivided into Divisions or Zones, depending on the frequency and period of exposure to hazardous substances.
Energy Efficiency- The LED technology uses much less energy than the usual lighting. This means they are an economical option for facilities that will need to be lit around the clock.
The company is the world’s best explosion proof lighting fixture supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Longevity- LED explosion proof lights can be applied in extreme conditions like high temperatures, moisture, and vibrations.
Safety- This light is designed with no risk of sparks or heat igniting flammable materials.
Low Maintenance- Due to the long-term life and less frequent maintenance periods, LEDs have fewer instances of downtime operations that encourage perpetual safety.
LED explosion proof lighting is critical to different industries:
Oil and Gas: in oil refineries, offshore rigs, and pipeline environments - it is fundamental for proper operation
Chemical Plants: proper lighting in a chemical spill area and under fumes.
Mining: visibility and safety underground in any location.
Food Processing: elimination of ignition points wherever combustible dust is concerned, especially from grains or sugar.
The following should be in your checklist for selecting LED explosion proof lights:
Q1: What is the difference between explosion-proofing and intrinsically safe lighting?
Explosion-proof lighting incorporates the ignition inside the housing, while intrinsically safe lighting runs at so low a power that any potential ignition cannot occur.
Q2: Is it safe to use LED illumination in all hazardous locations?
Yes, if the LED light meets the class and division or zone requirements of the particular hazardous location.
Q3: How long do explosion-proof LED illumination last?
Typically, explosion-proof lights have a lifetime rating of 50,000 to 100,000 hours, depending on their model and usage.
Q4: Can the non-hazardous areas use explosion-proof lights?
Yes, but as the lights are designed especially for hazardous environments, then definitely it would be overinvestment too.
Q5: How does one maintain explosion-proof lights?
Almost nothing has to be done on explosion-proof lighting because they rarely break down and are so highly lived.
LED explosion-proof lighting is a more efficient, energy-saving, and safer way to tackle hazardous places. Right classification and certification assure that the type of light used for protection in any facility keeps operational efficiency. Hence, in industries performing in risk environments, the investment into LED explosion-proof lighting cannot be an alternative but it must be there.
