Mencom – Hazardous Location

When electrical applications are used in or near hazardous environments where flammable gases, vapors, flammable liquids, combustible dust, or ignitable fibers may be present, there is a potential risk of a fire or explosion. According to article 500 of the National Electric Code (NEC) defined by The National Fire Protection Association (NFPA), these hazardous locations are classified using the ‘Class & Division’ system. The ‘Class’ is based on the general characteristics of hazardous substances in the surrounding atmosphere, and the ‘Division’ is defined based on the likelihood of the presence of hazardous materials.
