Fire / Smoke Damper Testing
Fire and smoke damper testing provides an essential fire safety service to your dampers, and complies with BS 5588-9 code of practice for ventilation and air conditioning ductwork.

This code of practice also includes BS 9999, which states that fire dampers should be cleaned and maintained at intervals stated below.
Fire dampers are crucial passive fire protection products used in heating, ventilation, and air conditioning ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors. In the event of a rise in temperature, the fire damper closes, usually activated by a thermal element. This melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades. Fire dampers can also close following receipt of an electrical signal from a fire alarm system utilising detector remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the duct system.
As they are open most, if not all of the time, it is vital to ensure that fire dampers will still close effectively when required. By providing a barrier beyond which the fire cannot pass, effective fire dampers save lives; so regular fire damper testing (known as drop testing) as well as fire damper cleaning and maintenance is both a legal requirement and a critical part of building fire safety management. We offer a fire damper testing, cleaning and maintenance service, in accordance with BS 9999:2008. This gives guidance for the two main types of fire damper: spring operated fire dampers – which should be drop tested, cleaned and maintained at intervals of no greater than 12 months; and non-spring operated models must be drop tested, cleaned and maintained at least every two years.
Fire/Smoke Damper Inspections to Include
- Inventory of all dampers to be tested.
- All Fire/Smoke dampers will be manually released to ensure the integrity of the spring loaded shutter.
- The Fusible link should be inspected for any deformity or damage.
- The Fire/Smoke Damper will be cleaned and lubricated within the closed position.
- The Fire/Smoke Damper shall then be opened and re-set.
- Any severe corrosion found shall be reported to the client.
- Test results with client information including position within the building/system, date, and name of operative shall be recorded and any comments noted if further action is required.
- Asset register to include damper location and ID number.
- Inspection results including details of failed damper operation.
- If drawings are provided, update and annotate details.
- Digital photographic evidence of damper condition prior to and after testing procedures unless otherwise specified by client.
- Explanation of failed operation and recommended corrective or remedial action.
What are the BS9999 Regulation?
In 2017, the BS9999 regulation – Fire safety in the design, management and use of buildings code of practice – was updated. This update was intended to provide good practices that safeguard the lives of those occupying buildings, and firefighters. BS9999 gives recommendations and guidance on the measures that should be taken to control or mitigate the effects of fire.
The standards’ main objective is to make sure that a reasonable standard of safety is possible in the event of a fire. With the revision, it also applies to the design of new buildings, to material alterations and extensions, and to change of material use for existing buildings.
The revision of BS9999 aligned the standard with current good practices, new technology, and other recently revised fire safety standards, including BS9990 and BS9991.
The main points of the revised BS9999 include:
- A flowchart showing the steps in the design process, assisting users in the application of the standard
- The revision of a clause regarding fire safety management
- The inclusion of fire suppression systems
- The guidance on voice alarms has been expanded
- More information is provided through an expanded fire growth rates table
- Updated recommendations for ducting, heat and smoke control, air-conditioning and ventilation systems, fire curtain barriers assemblies, and shopping centres
- Important new BESA guidance on fire & smoke damper testing
Maintenance of fire and smoke dampers from the Building & Engineering Association (BESA) outlines that where normal use of the ventilation system gathers an accumulation of dust, fire damper testing should be more frequent, to prevent contamination on the fire damper and its operational parts. The dust must be removed and the fire damper tested regularly to ensure that it operates as designed, should a fire occur. In a healthcare setting, additional care is needed to ensure that the fire damper also complies with Health Technical Memorandum (HTM) 03-01: Specialised ventilation for healthcare premises Part B: Operational management and performance verification. In care applications we will help the client to agree to a regular testing interval with the local fire prevention officer.
