Fire & Smoke Damper Inspection

Fire and smoke damper inspection is the periodic, documented testing of every fire damper and smoke damper in a building to confirm it will close and hold as required by NFPA 80 and NFPA 105 — the code requirement that protects life safety when a duct system penetrates a fire-rated wall or floor. dL Flow Tech is an independent firm that has performed fire damper inspections on commercial and institutional buildings across the Hudson Valley since 1982, producing the records that satisfy the authority having jurisdiction and the Joint Commission on hospital inspection cycles.

Why fire damper inspection is required

When ductwork passes through a fire-rated wall, floor, or ceiling assembly, the duct creates a potential path for fire and smoke to spread from one compartment to another. A fire damper is installed in that penetration to close automatically when a fusible link melts at elevated temperature, sealing the duct and preserving the fire compartment integrity the wall was designed to provide.

The problem is that a damper installed and forgotten will not necessarily function in a fire. Blades corrode and bind. Fusible links get painted over. Access panels get drywalled shut. Actuators lose power. A damper that looks fine in a walk-through may not close under fire conditions — and the only way to know is to test it.

NFPA 80 requires documented inspection and testing at 1 year after installation and at periodic intervals thereafter. The inspection has to be documented: a record of each damper, its location, its test result, and the technician who performed the work. That documentation is what satisfies the code official, the insurance carrier, and — in healthcare — the Joint Commission surveyor.

Fire dampers vs. smoke dampers — what's different

Combination fire/smoke dampers are common in healthcare settings; they must satisfy both standards and are tested for both functions during the same inspection.

The NFPA 80 inspection process

1. Locate and access every damper. We work from the as-built drawings to identify every fire and smoke damper in the building and confirm access panels are present and operable. Inaccessible dampers are documented as deficiencies requiring access provision.
2. Reset and test the fusible link (fire dampers). We reset the damper to the open position, trigger the closure, and confirm the blade closes fully and latches. Dampers that don't close fully or don't re-latch are documented as failures.
3. Test the actuator via the fire alarm system (smoke dampers). We coordinate with the fire alarm system to trigger the actuation signal and confirm the damper responds. We verify the blade position feedback or visual confirmation of closure.
4. Document each inspection point. Every damper gets a unique identifier, its location, its test result, and the technician and date. Failures are documented with the failure mode and cause where determinable.
5. Deliver the inspection report. You receive a complete record that satisfies NFPA 80, NFPA 105, and the authority having jurisdiction — including a deficiency list for any dampers requiring repair or re-inspection.

Healthcare fire damper inspection and the Joint Commission

For hospitals and other healthcare facilities, fire and smoke damper inspection is a Joint Commission requirement under the Environment of Care (EC) standards. The Joint Commission expects documented evidence that dampers are being tested on the required cycle, deficiencies are tracked through resolution, and the testing is performed by qualified personnel. The inspection records we produce are formatted to support EOC documentation and surveyor review.

Healthcare occupancies under NFPA 80 are allowed a 6-year inspection cycle rather than the standard 4-year cycle. We track inspection history across multiple site visits so the cycle remains current and documented.

What the inspection report includes

• A complete damper inventory with location, type, and unique identifier for each damper inspected.
• Inspection results — pass, fail, or inaccessible — for every damper.
• Deficiency detail for each failed or inaccessible damper, including the failure mode.
• The inspection date, technician, and standard under which the inspection was performed.
• A re-inspection record confirming repair and subsequent pass, where applicable.

Frequently asked questions

Which standard governs fire damper inspection?

Fire dampers are inspected per NFPA 80. Smoke dampers are inspected per NFPA 105. Both require inspection at 1 year after installation, then every 4 years for most occupancies (every 6 years for hospitals).

How often do fire dampers need to be tested?

NFPA 80 requires inspection at 1 year after installation, then every 4 years. Healthcare occupancies qualify for a 6-year cycle. Local authorities having jurisdiction may require a different frequency.

What happens if a fire damper fails inspection?

A failed damper is a code deficiency. It must be repaired or replaced and re-inspected before the inspection record is complete. We document all failures, identify the cause where determinable, and coordinate re-inspection after repair.

Do smoke dampers need to be tested separately from fire dampers?

Smoke dampers are governed by NFPA 105 and tested differently — via the fire alarm system rather than manual fusible-link reset. They are typically inspected on the same cycle but require coordination with the fire alarm system during testing.

What records do we receive after the inspection?

You receive a complete inspection report listing every damper location, its inspection result, the technician and date, deficiencies found and their failure mode, and certification that the inspection was performed to the applicable NFPA standard.
