Fire Damper Drop Testing

With fire dampers, late problems are big problems.  The fire damper drop testing should be carried out in ‘real’ conditions to show how they perform in different types of wall or ceiling installations and when subjected to different pressures through the ventilation system. 

It is vital to have Fire Dampers drop tested regularly to ensure they work to the best of their ability. 

It only takes 30 seconds for a fire to spread and become uncontrollable.

Insurance companies are taking greater interest in this area and will see lack of co-ordination in the project chain as compromising fire safety – they may choose to withhold cover as a result or dispute liability after a fire.

Fire dampers are used in heating and ventilation systems, too. They are used to reduce the fire hazard, by preventing the spread of fire through duct work throughout the building. Once the temperature raises to a certain point, the fire dampers are activated which prevents the spread of the fire through the duct work.

The Regulatory Reform (Fire Safety) Order 2005

The Regulatory Reform (Fire Safety) Order 2005 came into effect in October 2006 and establishes a general duty to ensure the safety of both employees and non-employees in the event of fire. 

The Main duty holder it the ‘responsible person’ who may be the employer, owner or other person who has control of the premises. The responsible person has to ensure that a ‘suitable and sufficient’ fire risk assessment is carried out, that suitable general fire precautions are provided and maintained.


Ventilation ductwork is a key area of potential fire risk and too many systems have failed to meet fire safety guidelines in the past.

Fire dampers and Fire smoke dampers have particularly suffered despite the key role they play in reducing injury and property damage in a fire. Fire damper standards have been in place for many years that require testing annually.
