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.
