Hazardous Emergency Lights – UL 844, Explosion Proof, Code Compliant

Hazardous emergency lights—also known as hazardous location emergency lights or explosion proof emergency lights—are designed for environments where flammable gases, vapors, or combustible dust may be present. These UL 844-compliant fixtures deliver reliable illumination during power outages without risking ignition in classified spaces.

  • UL 844 / UL 924 Certified
  • Explosion Proof
  • Industrial Rated
  • Battery Backup

These explosion proof emergency lights are constructed with sealed die-cast aluminum or fiberglass-reinforced housings. Designed for Class I Division 2 and Class II Division 1 & 2 environments, each unit resists corrosion, dust, moisture, vibration, and impact—perfect for industrial safety applications.

All models are UL 844 and UL 924 certified and feature internal battery backup for a minimum 90 minutes of egress lighting. High-output LED heads reduce maintenance and meet NFPA 101 life safety requirements.

💡 What is hazardous location emergency lighting? It's a sealed, code-certified fixture designed to provide safe emergency illumination without sparking ignition in explosive or combustible atmospheres.

Hazardous Location Ratings

Know your classification before you buy:

  • ✅ Class I Div 2 – Flammable gases or vapors present under abnormal conditions
  • ✅ Class II Div 1 – Combustible dust present during normal operation
  • ✅ Class II Div 2 – Dust present under irregular/fault conditions
💡 Pro Tip: When selecting explosion-proof emergency lights, verify Class/Division ratings, temperature code, and battery backup specs to ensure full OSHA and NEC compliance.

FAQs About Hazardous Location Emergency Lights

What qualifies as a hazardous location?

A hazardous location is any area where flammable gases, vapors, dust, or fibers are present in the atmosphere. These environments are classified by the NEC and OSHA as Class I, II, or III, and further divided into Division 1 or 2 based on the likelihood of hazardous materials being present during normal operations.

What’s the difference between Class I Div 1 and Class I Div 2?

Class I Division 1 zones have explosive gases or vapors present under normal conditions. Class I Division 2 zones only become hazardous during abnormal conditions—such as equipment failure, spills, or leaks.

Are battery backups required in hazardous emergency lights?

Yes. According to NFPA 101 and UL 924, all emergency lights—including explosion proof emergency lights—must provide at least 90 minutes of battery backup during power outages.

Can I use hazardous location emergency lights outdoors?

Absolutely. Many industrial emergency lights are sealed to NEMA 4X or IP66/IP67 standards, making them suitable for outdoor, marine, wash-down, or corrosive areas such as oil refineries, gas stations, and food-processing plants.

Do these fixtures use LED technology?

Yes. Most hazardous location emergency lights use energy-efficient LED lamp heads for maximum visibility, longer lifespan, and reduced maintenance compared to halogen models.

How do I choose the correct class and division?

Your classification depends on the type of hazardous materials and how often they’re present. For example, spray paint booths often require Class I Div 1, while storage areas with infrequent vapor exposure might fall under Class I Div 2. Always consult your site’s safety engineer or AHJ for proper classification.
