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 or fiberglass-reinforced polycarbonate—they feature NEMA 4X/IP66-rated, gasketed housings and impact-resistant lenses, making them resistant to water, dust, and corrosive environments.
Lighting options include high-output LED or MR16 lamp heads, delivering up to 1600 lumens with adjustable patterns. Units are equipped with durable battery backups (lithium-ion or Ni-Cd) that provide a minimum of 90 minutes’ runtime. Many also offer remote-head capability, dual-voltage input (120/277 VAC), and self-testing diagnostics to ensure reliable performance and simplified maintenance in extreme conditions.
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.
