Fire Damper Testing and Maintenance

Definition:

Fire Damper - A fire damper is defined as; “A movable closure within a duct which is operated automatically or manually and is designed to prevent the passage of fire”

Regular Maintenance

Fire dampers should be inspected annually as a minimum for correct function and condition in line with the Regulatory Reform Fire Safety Order 2005 and physically cleaned when required. Inspection and functional testing of smoke/fire dampers should be separately specified.

Maintenance of dampers is often overlooked as part of an overall maintenance regime, following the adage ‘out of sight, out of mind’. Dampers are located within ventilation and air conditioning ducts and designed to prevent the spread of fire inside the ductwork. This process forms a critical part of any passive fire strategy. In the event of a rise in temperature, typically caused by heat or smoke, the damper will close, usually activated by a thermal component. Heat or smoke identified within the system may indicate presence of a fire, which should activate the closure of the damper blades and prevent the spread of fire through the building.
