Classes, Divisions, Groups
Hazardous Lighting is categorized into classes, division, and groups and can be further categorized by zones.
For example, Class I consists of areas where inflammable gases or vapors may be present in sufficient quantities to produce explosive or flammable mixtures.
Hazardous Lighting Fundamentals Reference Guide Division II consists of areas where the hazardous condition is present due to accidental rupture, breakage or unusual faulty operation of a closed container or system. This combination is often found in a Zone 2 location; an area where an explosive gas-air mixture is not likely to occur, but if it does, it is only for a short period of time.
The commonly needed Class I, Div II classification has a number of fixture solutions depending on the application such as the Explosion-Proof LED linear fixture by Rig-A-Lite, the Fidelux FHAZ series, a multipurpose hazardous location fixture used in breweries and processing or the Phoenix Metallic LED VP Series used in walkways, doorways, stairwells and elevator pits.
There are three classes and two divisions and zones define the combination of these fixtures. Of course, there are many other considerations such as beam angles, and operating temperatures. The guide is designed to make quick work in determining the correct combination.
