Class I Division 2 Emergency Lights – Explosion‑Proof Fixtures for Hazardous Locations

Class I Division 2 emergency lights are engineered for hazardous industrial environments where flammable gases or vapors may occasionally be present. These explosion-resistant fixtures carry UL 924 and UL 844 listings for use in hazardous locations and are certified to withstand explosive atmospheres outside primary hazard zones.

Constructed with heavy-duty materials—die-cast aluminum exit sign housings or fiberglass-reinforced polycarbonate—they feature NEMA 4X/IP66-rated, gasketed enclosures and impact-resistant lenses, making them suitable for wet, dusty, and corrosive environments.

Lighting options include high-output LED or MR16 lamp heads, delivering up to 1600 lumens with adjustable coverage patterns. Units are equipped with long-life battery backups (lithium-ion or Ni-Cd) that ensure a minimum of 90 minutes of emergency runtime. Many models also feature remote-head compatibility, dual-voltage input (120/277 VAC), and integrated self-testing diagnostics for streamlined maintenance in demanding applications.

💡 What does Class I Division 2 mean? It refers to hazardous locations where flammable gases or vapors may be present under abnormal conditions. Emergency lights used in these areas must be sealed and ignition-proof to prevent sparks or heat from triggering combustion.

For additional rugged applications requiring moisture resistance or climate durability, explore our selection of wet-location emergency lighting fixtures and damp-location compliant emergency lights—ideal for non-explosive but harsh environments like loading docks, stairwells, and storage areas.
