What is Class 1 Division 1 LED Lighting?

Class 1 division 1 LED lighting

Class 1 Division 1 LED lighting (C1, D1) is mostly used in hazardous and very hazardous locations and areas. They are used to prevent high voltage and/or high amperage equipment from producing a spark or very hot elements (aka. a source of ignition). The obvious point is that you don’t see many LED lights giving off sparks, so why worry about it? The point is not to over-protect, but instead to add a layer of protection to what could become a source of ignition.


There Are Lights Built to Measure

You can often find whatever type of C1, D1 light you need from stores, but in some cases, you can have lights built to measure to ensure they are fit for purpose. The thing about C1, D1 is that they have a heavy-duty luminaire that surrounds any spark-producing components. If any sort of gas or vapor were to leak in and become ignited, then explosion is contained in a way that puts out any sort of fire within.

When it comes to general marine applications and industrial marine applications, waterproof and vapor proof fixtures are institutionally mandated.


Different Classes of Hazardous Location

You have class 1 hazardous locations that are split into two areas. Class 1 Hazardous locations are areas where flammable vapors or gases or vapors may become present high enough concentrations for them to produce an explosive or an ignitable mixture.

Class 1, Division 1: There are three different situations that could exist to classify an area as a Class 1 Division 1 area interest location.

Hazardous Location One – The release of any ignitable concentrations of vapors or gases. In this case, the release is due to any sort of equipment breakdown, which may also cause electrical equipment failure at the same time.

Hazardous Location Two – During working operations there is an expectation for a degree of vapors or explosive liquids to be present. They are expected as part of the process and are dealt with accordingly.

Hazardous Location Three – Where the act of repair or maintenance is the reason why there are concentrations of vapor or gas that may ignite or explode.


Finding the Right Type of LED Light

If you are working within one of the three hazardous locations above, then you are expected to have Class 1, Division 1 LED lighting. This ensures that the lights do not cause explosions or fires. Just make sure you buy them from a legitimate and licensed source, such as from LED Pros World Wide.

Be aware that if you decide to “Cheap out” and buy them secondhand, then you have no idea if they are fit for purpose. The same is true if you decide to bulk-buy them from a Chinese company since they are not bound by the same standards as most other developed countries.

If you cannot prove that you bought your C1,D1 lights from a legitimate source such as LED Pros World Wide, then your insurance company may refuse to insure you because having the correct types of lights in hazardous locations is legally required.
