Safety Lights - approved for use in hazardous environments
The National Electric Code (NEC) defines hazardous locations by "class" and "division."
There are three classes as follows:
Class 1 locations are made hazardous by the presence of flammable gases, liquids or vapors.
Class 2 locations are described as hazardous because of the presence of combustible dusts.
Class 3 locations contain easily ignitable fibers or flyings.
"Division" refers to the likelihood that ignitable concentrations of flammable materials are present.
Division 1 designates an environment where ignitable concentrations of flammable gases, liquids, vapors or dusts can exist some of the time or all of the time under normal operating conditions or where easily ignitable fibers and flyings are manufactured, handled or used.
Division 2 locations are areas where ignitable concentrations are not likely to exist under normal operating conditions or where Class 3 materials are stored or handled.
