Fire-Rated Options Up to 4 Hours
Explosion-proof storage is frequently combined with fire-rated construction to provide both blast-safe and fire-rated protection.
We offer:
Non Fire-Rated (0-Hour)
For remote outdoor placement away from structures.
1-Hour Fire Rating
Meets basic requirements for many flammable storage applications.
2-Hour Fire Rating
Allows placement closer to existing buildings.
4-Hour Fire Rating (Highest Level)
For high-risk environments, occupied facilities, manufacturing operations, or areas requiring maximum separation from personnel and structures.
Our 4-hour fire-rated explosion-proof lockers include:
- High-mass steel and fire-rated insulation systems
- Fire-tested assemblies
- Fire-rated doors
- Industrial fire dampers and closures
