Hazardous emergency lights—also called hazardous location emergency lights or explosion-proof emergency lights—are built for classified spaces with flammable gases, vapors, or combustible dust. These fixtures pair sealed, corrosion-resistant housings with high-output LEDs and battery backup to provide reliable egress illumination in Class/Division areas. For related signage, see explosion-proof exit signs or browse all emergency lights.
Constructed in copper-free die-cast aluminum or fiberglass-reinforced housings with sealed gaskets and 1/2" NPT conduit hubs, these lights resist corrosion, dust, moisture, vibration, and impact—ideal for refineries, chemical plants, paint booths, grain handling, and other industrial sites. Adjustable LED optics provide efficient coverage along paths of egress while minimizing maintenance.
Most models are UL 844 listed for hazardous locations; many also carry UL 924 emergency-lighting listings and provide a minimum 90 minutes of battery runtime (verify per spec). Match your environment by checking temperature code (e.g., T4/T6), gas/dust group, and ingress protection (e.g., IP65/IP66).

Know your classification before you buy: Class I Division 2 exit signs — flammable gases or vapors present under abnormal conditions; Class II Division 1 exit signs — combustible dust present during normal operation; Class II Division 2 exit signs — dust present under irregular or fault conditions.
A hazardous location is an area where flammable gases, vapors, dusts, or fibers could ignite. These spaces are categorized by the NEC (and referenced by OSHA) as Class I (gases/vapors), Class II (dusts), or Class III (fibers/flyings), and split into Division 1 or 2 based on how often the hazard is present.
Class I, Division 1 means explosive gases/vapors are present under normal operating conditions (e.g., paint booth interiors). Class I, Division 2 means they’re only present under abnormal conditions, like leaks or equipment failure (e.g., adjacent storage or piping areas).
Yes. Per UL 924 and NFPA 101, emergency lights—including explosion-proof models—must provide at least 90 minutes of illumination during a power outage.
Yes—choose units rated for harsh environments, such as NEMA 4X or IP66/IP67. These are suitable for outdoor, marine, wash-down, or corrosive areas (e.g., refineries, gas stations, food-processing lines).
Most hazardous-location emergency lights use LED heads for higher efficiency, long life, and lower maintenance compared with halogen.
Match the classification to your materials and how frequently they’re present. For example, active spray areas may be Class I, Div 1, while nearby storage or ventilation spaces may be Class I, Div 2. Confirm with your local fire marshal or building inspector.
