Does YouR Facility Need Explosion Proof Lighting?


When it comes to facility safety, flammable or explosive environments are the biggest lighting-related risk. The volatile combination of explosive gases, dust or fibers in the air, combined with the potential for ignition from an arc or spark from a malfunctioning light – or even just the high heat output from most fixtures – can have dire consequences. Environments where flammable or volatile airborne matter may be present are classified as hazardous locations using a a classification system that varies slightly by region or country.

UL Classifications Used in the United States

  • CLASS I – environments where flammable gases or vapors are present in the air in quantities sufficient to produce explosive or ignitable mixtures.
  • CLASS II – environments where there is the presence of combustible or conductive dust
  • CLASS III – environments where the presence of easily ignitable fibers or where materials producing combustible flyings are handled.

Each class is broken down further into divisions and groups to identify the specific types of vapors, gases, dusts, or fibers that are present in the area.

Non-compliance with regulations can result in hefty fines, but that's only the beginning. If the incorrect fixtures are installed, they must be replaced with code-compliant fixtures. Lights installed in hazardous locations are required by law to meet OSHA, NFPA, or NEC/CEC requirements. Companies caught using non-compliant lights in hazardous areas may face litigation, which can be very expensive. When you need safe, reliable lighting you can count on, you need Dialight. Ask your local McNaughton-McKay sales representative how to choose the right fixture to meet your hazardous needs to stay safe and compliant.
