Why it is Important to Have Fire Damper Testing?

Fire dampers are designed to prevent the spread of fire throughout the ductwork and other areas of your building. When working correctly, your fire dampers will close automatically as soon as excessive heat is detected. It is therefore critical that the mechanisms on these devices are functioning correctly in the event of a fire. 

Since fire dampers are usually hidden within the ductwork or the ceiling, it is easy to forget about them. As you cannot readily access these devices routine testing and maintenance must be carried by a certified expert.

Fire Damper Testing Requirements

In accordance with the British Standards 9999:2017, all fire dampers should be drop tested, cleaned, and routinely maintained within a minimum of years, and spring operated fire dampers should be tested at least once a year. 

All Products used on-site by Duct Cleaning London are fully tested to BS EN 1366-2 & BS EN1751 Standards.

Our Maintenance Programme ensures that all existing and new fire dampers are being tested within a 12-month timeframe.

Our testing routines include:

  • Free comprehensive site survey
  • The identification of all fire damper devices
  • Maintenance and cleaning
  • Fire damper testing procedures
  • We provide a certificate of inspection

Fire Damper tests carried out during an inspection include:

  •  A free comprehensive site survey
  •  Checking for damages or obstructions to the safety curtain
  •  Maintenance and cleaning
  •  Checking of the functioning of internal blades and spring mechanisms
  •  Ensuring that channels and side rails free from obstructions
  •  Checking of fusible links
  •  Drop testing of the fire damper to confirm correct operation
  • A certificate of the completed inspection provided

Consequences of Neglected Fire Dampers

Neglected fire dampers will result in a system that can not be depended on in the event of a fire. Over time particles and residue can build up, preventing the mechanisms from working properly which will inevitably lead to the safety curtain failing to close and the spread of fire throughout the duct and other areas of the building.

Fatalities caused by fire damper neglect may result in prosecution under the Corporate Manslaughter Act. Fire damage caused by a fire damper that has not undergone the required routine maintenance may void your insurance cover.
