Fire Damper Drop Testing

Fire dampers are fitted in ductwork where it passes through a fire compartment barrier. They are designed to shit when a specified temperature is met, preventing the spread of fire and smoke.

In the event of a fire, they can buy precious time and help to save lives and property from damage. In many buildings, the location and condition of fire dampers is unknown to the responsible person, who must ensure that they are present, properly maintained and regularly tested, in compliance with BS 9999:2017.
