1. Visual Inspection
We begin with a visual review to assess whether the fire damper is properly installed and free from damage or obstruction.
2. Drop Test Procedure
Using a manual release of the fusible link, we ensure the damper closes completely. This is the most reliable way to test a damper’s mechanical operation.
3. Compliance Check
All testing is carried out to meet the latest British Standards, including:
- BS 9999 (fire safety in design and management)
- BS EN 1366-2 (fire resistance of dampers)
- HTM 03-01 (for hospitals and healthcare facilities)
- NFPA 90A (additional international guidance)
We tailor testing to suit your building type, whether it’s a restaurant kitchen, office block, hospital, or retail premises.
4. Maintenance Reporting
After testing, we provide a clear report documenting:
- Test results for each damper
- Any failures or malfunctions
- Required repairs or replacements
This report supports your compliance obligations and can be used for internal audits or insurance records.
A. A drop test checks whether the fire damper will close properly when triggered. It involves releasing the fusible link and confirming the damper fully shuts.
A. This depends on access and the number of dampers. Most commercial properties can be tested within a day. We can work outside business hours to reduce disruption.
A. Yes. Under BS 9999, fire damper testing is required for all buildings using ducted ventilation systems. Neglecting testing may lead to non-compliance penalties or increased insurance liability.
A. We’ll document the failure and recommend immediate remedial action. Our engineers can arrange follow-up repairs or replacements as needed.
