Fire Damper Testing

Fire Dampers are a vitally important part of any ventilation system and need to be part of a Fire Damper
maintenance programme to ensure correct operation.
BS9999 Fire Damper Regulations call for the following:

“Arrangements should be made for all Fire Dampers to be tested by a competent person on completion of
installation and at regular intervals not exceeding 1 year, and to be repaired or replaced immediately if found

to be faulty”.

Spring operated Fire Dampers should be tested annually and Fire Dampers situated in dust laden and similar
atmospheres should be tested much more frequently, at periods to suit the degree of pollution.
Our Scope of Works includes:
The inspection, servicing and testing of the fire and smoke dampers referenced on the schematic drawings, CAD
plan or building asset list. Providing a comprehensive report on completion of works detailing the information
collected on each damper including the following:

· Pre & Post Photograph of each damper
· Dimensions
· Condition of damper
· Location
· Recommendations
· Type of fire damper
