Fire damper management

Failed or inaccessible fire dampers: what should happen next?

A service visit may identify a failed test, an installation concern or a damper that could not be reached. These are different findings and need different next steps. Keep each result tied to the correct asset, agree who will act and record how the concern is resolved.

Separate a failed test from an untested asset

Ask the service team to state what was inspected, which functional checks were completed, the result and any limitation. 'Not accessed' does not mean passed, and a passed functional check does not by itself resolve a separately reported installation defect. An asset missing from the register may need identification before its history or inspection requirements can be understood.

Arrange a competent assessment of failures

A failed result needs a recorded explanation where it can be established safely, and a suitable remedial scope. Possible concerns include obstruction, damage, contamination or an operating component problem. The solution depends on the damper type, installation and manufacturer instructions. Building managers should not force, disable or modify the mechanism to obtain a pass. Agree priorities and any interim arrangements with the building team and relevant competent advisers.

Treat access as a defined work item

Where a damper cannot be reached safely, ask what prevents the inspection and what access is needed. The answer may involve identification, a permit, isolation, equipment or an access opening; it should not be reduced to an instruction to cut a hatch anywhere nearby. Alterations to walls, ceilings or services need consideration of the building construction and fire strategy. Confirm the access solution and responsibility before arranging a return visit.

Confirm operation and final condition after work

After the agreed remedial work, arrange the applicable checks and record the result. The service team should confirm reset and final operating condition where relevant, and report any issue that remains. Not every damper uses the same test method: a gravity or spring-operated unit, an actuated damper and a smoke-control system may have different requirements. Follow the appropriate manufacturer and system information rather than applying one generic drop-test procedure.

Keep the servicing programme and records current

Retain original findings, remedial work and verification under the same asset reference. Record inaccessible units on the action schedule until the required inspection has taken place. The annual benchmark discussed in our frequency guide must be considered alongside system type, manufacturer instructions, building requirements and conditions that may warrant earlier attention. Avoid treating the next routine service date as the automatic deadline for resolving a known defect.
