Our service provides everything from testing and maintenance through to remedial rectification works.

What is a Fire Damper?

Fire and smoke dampers are generally passive fire protection products fitted into ductwork to prevent the spread of fire inside the ductwork from compartment to compartment. Fire dampers are not part of the ventilation system and are considered part of the fire protection compartment. Fire dampers are crucial in helping to minimise any damage to the structure itself and most importantly to protect the people within the building.

Testing Legal requirements

Fire damper testing is a legal requirement and is covered under BS:9999 and the Regulatory Reform Fire Safety Order 2005. There is many references to fire damper testing, maintenance, installation and requirements in various legislative documents and all must be adhered to especially considering the use of the building. The main outtake for testing is highlighted below:

BS:9999 Annex W Note 1: “Arrangements should be made for all fire dampers to be tested by a competent person on completion of the installation and at least annually, and to be repaired or replaced immediately if found to be faulty.”

Why do Fire and Smoke Dampers Fail?

As a compliance delivering service fire damper failures will be present in systems. All failures must be reported and acted on keeping to the above legislative statement taken from BS:9999 Annex W Note 1. Certain factors can contribute to a fire damper being a failure but what has to be considered there can be several of these faults that can be present on just one fire damper these are as follows:

  • Operation
  • Orientation
  • Obstruction
  • Access
  • Compartmentalisation
  • Corrosion
  • Illegal Installation

It might take only one faulty damper to allow the spread of a fire and present a risk to life. Therefore it is imperative that the annual fire damper testing regime is completed by a qualified competent person and carried out to the relevant legislative requirements for that premises use.
