The short answer: every fire and smoke damper should be drop-tested by a competent person at least once a year, more often in dirty or grease-laden systems, and the Regulatory Reform (Fire Safety) Order 2005 article 17 makes maintaining them in efficient working order a legal duty on the responsible person. The test is a physical release, not a glance through an access panel, and the record has to prove it happened.
Where the duty comes from
| Requirement | Where it comes from |
|---|---|
| Dampers maintained in efficient working order and good repair | Regulatory Reform (Fire Safety) Order 2005, article 17 |
| Drop test at least annually, more often in adverse environments | BS 9999 (maintenance recommendations for fire and smoke dampers) |
| Installation and access provision | BESA DW/145 |
| Healthcare premises: enhanced regimes in critical areas | HTM 03-01 (NHS ventilation guidance) |
What a drop test actually involves
- Locate and access the damper: in older buildings this is often the hard part, and fitting access panels is frequently the first job.
- Release the damper so the blade is seen to close fully: a thermal or mechanical release, not a visual check.
- Inspect the blade, seals and tracks for corrosion, dust and grease.
- Reset, prove the damper open, and confirm any actuator or panel signal.
- Record the result against a floor plan, with photographs, and list every damper that failed or could not be reached.
The honest industry secret is that a meaningful share of dampers fail their first-ever test, usually seized by dust, corrosion or paint, and a damper that cannot be reached has to be reported as untested, not assumed good. That is why the record matters as much as the visit: when an inspector or insurer asks, the answer is your paperwork.
Common failures we find
Seized blades in dusty extract systems, fusible links painted over during refurbishments, dampers boarded behind plasterboard with no access, actuators disconnected during other works and never reinstated, and dampers missing entirely where drawings say they exist. Each one is a hole in a fire compartment wall until it is fixed.
Frequently asked questions
Is fire damper testing a legal requirement? Effectively yes: article 17 of the Fire Safety Order requires fire safety provisions to be maintained, and BS 9999 is the benchmark any court or enforcing officer will reach for. An untested damper is an unmaintained one.
What if a damper is inaccessible? The report should say so plainly, and the fix is an access panel, not a caveat. We fit them as part of the programme.
Who can test fire dampers? A competent person with the training, equipment and recording discipline to do it properly; our teams test, photograph and log every damper against the drawings.
Testing is delivered through our fire damper testing service, with before and after evidence per damper. Where dampers sit above suspended ceilings in occupied buildings, the same visit can cover AOV and smoke vent testing, and for healthcare estates we work to the HTM regimes. One team, one record, no gaps.
