Class 1 Div 2 Lighting

What is Class 1 Div 2 Lighting?

Class 1 Div 2 LED Lighting fixtures are explosion-rated lighting. They work in explosive hazardous classified environments and hazardous locations where flammable gas and explosion hazard are sometimes present. Conditions include high concentrations of flammable gases and combustible vapors, liquids, or gases. You will often find Class 1 Div 2 Light Fixtures used in outdoor applications. As an electrician, C1D2 lighting requirements are defined in the national electric code and national fire protection association.

What are the Benefits of Class 1 Div 2 Lighting in Hazardous Locations?

Like other LED lights, Class 1 Div 2 LED Light fixtures provide the same key benefits – energy saving, reduced maintenance, and improved quality of light. They also meet the certification requirements needed in a Class 1 Div 2 application. They will provide a safe lighting environment.

Is Atex Rated the Same as Class 1 Div 2?

It’s not. ATEX (ATmosphere EXplosibles) is a competing France certification. In the United States, we rely on the UL844 certification for Class 1 Division 2 Light fixtures, not the ATEX standard.

Can I Get Away with Using a Vapor Tight Fixture when Flammable Gases are Present?

No. Never use a vapor-tight fixture in place of a Class 1 Div 2 LED lighting fixture. It does not provide the safety and certification required for hazardous locations. Vapor-proof fixtures are perfect for the applications they are designed for. But they are not designed to replace Class 1 Division 2 lights.

What is a Class 1 Div 2 Hazardous Area?

Class 1 hazardous areas are defined as groups. Groups are categorized by the type of material found. The most common groups are: (A) Acetylene, (B) Hydrogen, (C) Ethylene and/or Propane, and (D) Propane, Butane, Methane, and Benzene. The difference between Division 1 and Division 2 is whether the hazardous environment is always or sometimes present.

Does Class 1 Div 2 Require Intrinsically Safe Certifications?

It does not. Class 1 Div 2 LED lighting can be either explosion-proof rated or Intrinsically safe lighting. These are two different ways engineers came up with solving the same problem. The lights cannot create an explosion inside a hazardous environment.

Does Class 1 Div 2 Need a Seal?

UL844 Class 1 Div 2 certification is very specific about what a fixture must or must not have. If you buy a light that is tested and certified to this standard, you met the requirement. There is no concern about needing to supply an extra seal for these fixtures, it is 100% complete.

Is Ip66 Wet Location Rating the Same as Class 1 Div 2?

No. IP66 is a dust and water ingress standard. It is used to tell you how waterproof and dustproof the fixture is. Our c1d2 led lights are also IP66 (or higher) rated, but that is not the standard that makes them explosion-proof.

Do You Have Class 1 Div 2 Lighting in Stock?

What Accessories are Needed to Install Class 1 Div 2 Lighting?

Everything this light connects to inside the room also needs to be Class 1 Div 2 rated or higher. There are some accessories available, but they are limited due to the special nature of this fixture. Let us know what your needs are and we can identify the exact requirements you have.

Is the Cord Coming out of the Fixture Rated Class 1 Div 2 or Do I Need to Remove It?

Most of our C1D2 Hazardous Location LED Lighting includes at least a 1-foot power cord. It is intended to show how the fixture is wired. In most cases, the installation includes wiring to the driver/wiring box on the fixture. Your local Building Inspector or Fire Marshall governs installation and wiring requirements. Please refer to them for explosion-proof fixture requirements for new installations. If you already have fixtures installed that you are upgrading, in most cases you will be able to reuse the conduit and junction boxes. This is assuming you will be mounting the same as the current installation. The installation of explosion-proof fixtures requires no exposed bare wires.

How Do I Install Class 1 Div 2 Hazardous Location LED Lighting?

You should never do this by yourself. This must be done by a qualified electrician.
