Lighting for Hazardous Locations

A hazardous location is defined as the presence of a specific concentration of fuel in an environment where electric service is also available. They include: Flammable Gases and Liquids, which have an ignitable range of concentration, and Dust/Fibers and Flyings, which are combustible.

Auto Ignition Temperature (AIT) is used to determine the required maximum operating temperature of heat-generating devices, including luminaires. These devices must be designed to contain all sparks or flames generated during normal or abnormal conditions, and must not exceed the maximum operating temperature required for this environment.

The National Electric Code (NEC) classifies potentially hazardous materials and conditions. Basic requirements for Class I Division 2 electrical equipment are no arcing or sparking parts be present, or if present, be in an explosion-proof enclosure. Kenall’s hazardous-rated SimpleSeal products are approved for use in Class 1, Division 2, Groups A, B, C, and D.
