How Do You Determine If a Light Is Explosion Proof?

In the USA, the light needs to be certified to UL844 standard. Beyond that, you have to determine what certification applies – Class 1 Div 1 and Class 1 Div 2 are the most common.

There are other certifications – like ATEX, that apply to other countries, but in the USA, Canada and locations near here, make sure it is UL844 certified.

What Is the Difference Between Flame Proof Lighting and Explosion Proof Lighting?

A flame proof light is one that is built with materials that inhibit flames. Explosion proof lighting are fixtures designed to run safely in a hazardous environment. A flame proof light should never be used in place of an explosion proof light in a hazardous environment.

Are All LED Lights Explosion Proof?

Not all LED lights are explosion proof. The fixture needs to have been tested under the UL844 certification to be considered explosion proof. Do not confuse vapor proof with explosion proof, they are not the same thing. Never use a vapor tight fixture in an environment where explosion proof lighting is needed and required.

What Are Intrinsically Safe LED Lights?

Intrinsically safe lighting fixtures differ from explosion proof lighting fixtures in that they are designed so they cannot create an explosion or spark. For the most part, they tend to be low power, low voltage lighting and often are battery-powered.

Why Would an LED Bulb Explode?

An LED bulb, by itself, should never explode. But if this bulb inadvertently creates a spark in an explosive environment, it could cause an explosion. By nature, a spark, or explosion inside an explosion proof fixture, will never escape outside the fixture.

Are Vapor Tight Rated Fixtures Explosion Proof?

No. A vapor tight fixture is designed to keep non-explosive gases and dust from entering the fixture and causing premature failure of the fixture. It is not designed to keep an explosion caused by the fixture from escaping into the external hazardous environment it’s installed in. Although we sell LED Vapor Tight fixtures, they should never be used to replace an explosion-rated fixture.


How Does Explosion Proof Lighting Work?

The light is designed to prohibit an explosion that might start within the fixture from escaping to the environment it’s installed in. It is not vapor tight, as some may think. The light is designed with a series of channels causing any explosion that might start inside the fixture to cool down – and by the time it leaves the fixture, it’s been de-fused.

Where Are Your Explosion Proof Lights Manufactured?

Our explosion proof lighting fixtures are manufactured in our overseas facilities and we stock these fixtures in the USA. If a BAA (Buy America Act – usually required for government contracts) explosion proof fixture is required, we can also supply the USA made versions. Our BAA versions usually carry a 4-week production lead-time.

What Temperature Can the Explosion Proof Lighting Handle?

Our explosion proof lighting fixtures are rated between 121F to 149F (up to 185F for Exit Signs). We indicate on each product what the upper operating temperature is.

Do You Have a Portable Battery-Operated Explosion Proof Light?

We have a battery-operated portable work light that works off batteries. It weighs 15 pounds and can be carried to locations where you need instant explosion proof rated lighting. It is both Class 1 Div 1 and Class 1 Div 2 rated.

Are Explosion Proof Lights Shatter-proof?

Our explosion proof lights are all IK10 rated. This is the highest impact rating that can be obtained by any LED Fixture. All our fixtures come with a tempered glass lens that is IK10 rated-shatter proof.

Where are Hazardous Area Lights Used?

Hazardous area / explosion proof lighting fixtures should be used in areas where hazardous gas and dust conditions exist all the time or some of the time.

Types of Explosion Proof Lighting

Our explosion proof lights are also IP65 or higher rated, so they can be used both indoors or outdoors. Our lights are extremely adaptable, so they can replace many existing metal halide and fluorescent fixtures including:

High Bays and Low Bays
Linear Strip Fixture
Flood Lights
Jelly Jars
Temporary Work Lights
Exit Signs


What Are the Best Applications for Explosion Proof Lighting?

LED explosion proof lighting fixtures are designed to replace, one for one, metal halide and fluorescent fixtures in indoor and outdoor hazardous locations. For new installations, our lights are designed to be installed in hazardous explosive locations. These include industrial applications such as:

Chemical processing plants
Aircraft maintenance areas
Enclosed fueling stations
Paint spray booths
Offshore oil and gas rigs
Chemical storage units
Ship tanks
Oil and gas storage
Grain silos

What’s the Difference Between Class Div 1 and Class 1 Div 2?

Class 1 Division 1 hazardous locations are areas that have flammable gases, vapors, and liquids and are present at all times. Class 1 Division 2 locations are areas that have the same flammable gases, vapors, and liquids but are not present at all times.

Can You Substitute a Class 1 Fixture for Classes 2 or 3?

No. Unlike divisions described above, you cannot swap fixtures among classes. It is either rated for the Class you need or it isn’t.

Can you use a Division 1 Fixture of a class in a Division 2 Area of the Same Class?

Yes, that assumes that both have the same grouping certification. For example, Class 1, Div 1, Group C can be used in Class 1, Div 2, Group C.

What’s the Difference Between Class 1, Class 2 and Class 3?

Class 1: Gases – Areas in which flammable gases or vapors are present.
Class 2: Dust – Areas in which combustible dust may be suspended in the air or accumulates on electrical equipment.
Class 3: Fibers Areas in which easily ignitable fibers are present.

What Are The Groups in Class 1?

Group A: Acetylene
Group B: Hydrogen
Group C: Ethylene
Group D: Propane

What are the Groups in Class 2?

Group E: Electrically conductive dust
Group F: Carbonaceous dust
Group G: Agricultural and polymer dust


What Are the Mounting Bracket Options?

The main and most common mounting options available are:

Pendant – the wiring runs through the pendant into a junction box.
Trunnion / Yoke Mount – wired with flex pipe to a junction box.

There are some custom mounts that are also available:

Slip Fitter / Pipe Mount – For pole mounting – square fixture
Surface Mount Arm – for wall mounting
Stanchion Mounting – for pole mounting – round fixture

How Do I Replace an Explosion Proof Light with LED?

Our lights are designed to be a 1 for 1 replacement for metal halide and fluorescent lighting. It should be as simple as removing the existing light and replacing it with the new light. We recommend using a certified electrician who is familiar with explosion proof lighting when replacing these fixtures.

Do your Fixtures Come with a Whip or Cord?

It does not, and the reason is, everything inside a hazardous location room needs to be explosion rated, including the junction boxes and conduit that supplies power to the fixture. Unlike a normal high bay, an exposed power cord/whip does not make sense.


How Do You Layout Explosion Proof Lights?

The best way is to create a lighting plan.

A lighting plan uses specialized lighting software to create a model of your indoor or outdoor space, place explosion proof lighting in this space, and then calculate light levels and how balanced the light is in the area.

It takes away all the guesswork and makes converting to LED lights simple and easy.
