Fire Damper Testing

Fire dampers are essentially fire safety metal curtain devices that fall within your buildings air ventilation ductwork systems in the event of a fire within a building.

 

 

Fire dampers are designed to stop fire and smoke spreading through a building and are strategically positioned at various places where ductwork passes through fire compartment walls, floors or zones within a building.

 

They are life saving pieces of equipment and a vital part of a buildings fire safety, designed to help contain a fire within a certain zone for a period of time, so that a building can be evacuated and fire fighters can reach and concentrate their efforts on a blaze that has been kept within a contained area of the building.

Why Should fire dampers be tested?

Not only is it a requirement to comply with British Standard BS 9999 But testing fire dampers can also save lives ensuring they are working and fit for purpose.

How often should fire dampers be tested?

According to the updated BS 9999:2017 all fire dampers should be drop tested, cleaned and maintained at least every 12 months.

What GWS Will Do

  • Locate Each fire damper to provide inventory of Dampers to be Tested. 

  • Access doors can be supplied and fitter if required. 

  • Each fire damper are manually drop tested, cleaned and reset.

  • Fusible Link to be inspected for any deformity or damage.

  • Provide records of each test including before and after photo's.

  • Report of any problems or recommendations.

  • Carry out any remedial work.

On completion of a satisfactory test, it is essential that the damper is correctly reset, so it is ready in an emergency. Our team is skilled at resetting fire dampers and replacing fusible links, if necessar

What we look for? Operatives will then need to carry out an internal visual inspection of the dampers looking for:

  • Damage or obstructions to the curtain

  • Internal blades operating and closing fully

  • Spring mechanism working

  • Channels and side rails clear of any obstructions

  • Fusible link in-tact and correct type fitted

  • Dirt, dust or contamination levels of the ductwork that could be causing the fire damper to not fully close or operate correctly in the event of a fire

  • Drop testing the Fire Damper to ensure correct working order

  • Any other faults.

All fire safety systems must be regularly and professionally maintained to ensure the safety of building occupants – a faulty fire damper will not prevent the spread of fire. With the enactment of the Regulatory Reform (Fire Safety) Order 2005, it is now the employer’s responsibility to maintain their fire safety systems

Fire dampers are located where ductwork passes through fire compartment walls and floors. They are typically held open by a ‘fusible link’, which BS 9999:2017 defines as a ‘device that releases a component such as a fire damper or fire shutter at a set temperature.

 

When met by high heat, a fusible link will release and close the fire damper. The fusible link can also be released manually, for testing purposes. Our experts will manually release the fire damper and visually check the integrity of the mechanism. All fire dampers should close fully on release – it is the integrity of the closure that prevents the spread of smoke and fire in an emergency situation

Evidence 

Completing a testing routine is insufficient for compliance. You need to maintain accurate records of when testing was carried out. Our team produces an industry-leading fire damper testing report, which includes photographic evidence of testing, to satisfy authorities that testing has been conducted.
