Why Certain Facilities Require Explosion Proof Lighting
Hazardous locations contain substances that may ignite if exposed to:
- Electrical sparks
- Electrical arcs
- Excessive heat
- Hot surfaces
- Equipment failures
Explosion proof fixtures are specifically designed to contain internal ignition events and prevent ignition of surrounding hazardous atmospheres.
Without certified equipment, facilities may face:
- Worker safety risks
- Regulatory violations
- Increased liability
- Failed inspections
- Property damage
- Production downtime
