Annual fire damper inspections might not grab headlines—but they’re essential for protecting lives and controlling fire and smoke spread through your HVAC systems.
Fire dampers are designed to automatically close when high heat is detected, sealing off air ducts and preventing dangerous conditions from worsening. But like any mechanical system, they need regular attention.
Annual inspections, per NFPA 90A and referenced in NFPA 101 Life Safety Code, should include:
- Visual checks for obstructions and corrosion
- Testing of activation mechanisms and fusible links
- Verification of proper installation and labeling
- Documentation of each damper’s location and test results
Facilities seeking AAAHC accreditation or operating under NFPA compliance frameworks must treat fire dampers as a core safety priority—not a background task.
✅ Tip: Schedule damper inspections alongside HVAC maintenance with other life safety tasks, like emergency lighting checks or fire barrier reviews, and ensure every component functions as designed.
