Explosionproof Emergency Lights

Some things don’t mix, like gasoline and a match. There are others that are just as dangerous, but not quite so obvious as that; such as flammable liquids and electrical lighting. While the electrical lighting seems innocent enough, the fact of the matter is that an electrical light can cause sparks. In an environment filled with flammable gases or vapors, that’s all it takes to start a fire.

Explosionproof Lights are a bit of a misnomer, as lights don’t normally explode. Instead, they are lights that are designed to not cause explosions, by not providing that one little spark to ignite flammable vapors and gasses.

Categorizing the Danger:

To properly select Explosionproof Emergency Lights for a particular installation, one needs to understand the environmental risk of the place where they will be installed. There are three different “classes” of risk, based upon the type of flammable materials that can be present in the area:

• Class 1: refers to combustible gases or vapors
• Class 2: refers to combustible dust
• Class 3: refers to combustible fibers or flyings

Of the three, it is clear that Class 1 is the greatest risk. Therefore, most Explosion Proof Emergency Lights are designed for use in a Class 1 environment.

In addition to the class system, there are two divisions, which categorize the probability of having those combustible gases, dust or fibers in the area.

• Division 1: refers to areas where the flammable materials are present as a normal part of your operation.
• Division 2: refers to areas where the flammable materials could exist, but only in abnormal circumstances.

When selecting Explosion Proof Emergency Lights, it is important to consider both the Class and the Division for the application.

What is Different About Explosionproof Emergency Lighting?

Explosionproof Emergency Lights are manufactured differently than standard emergency lights. The biggest difference is that the case and lamp heads are fully sealed against the entry of gases and other flammables. This insures that in the case of an inadvertent spark within the unit, there will be nothing combustible in the same place as the spark.

Additionally, these units are built to withstand any damage from the outside, caused by flying debris from an explosion. While they are not as immune to explosion as an army tank, they are rugged, survivable units. That way, they can continue to provide emergency lighting for rescue or for survivors in the area.

What’s the Same About an Explosionproof Emergency Light?

Just like all other emergency lights, explosionproof units need to be designed to switch on immediately, in the case of building power loss. They are required by regulation to remain illuminated for a minimum of 90 minutes.

When installed, they must provide the same level of lighting that is required for emergency lighting in any other public or commercial facility. Testing of these units must be performed on a monthly and annual basis.
