What is a fire damper drop test?
Fire dampers are located where ductwork passes through fire compartment walls and floors. They are typically held open by a ‘fusible link’, which BS 9999:2017 defines as a ‘device that releases a component such as a fire damper or fire shutter at a set temperature’.
When met by high heat, a fusible link will release and close the fire damper. The fusible link can also be released manually, for testing purposes. Our experts will manually release the fire damper and visually check the integrity of the mechanism. All fire dampers should close fully on release – it is the integrity of the closure that prevents the spread of smoke and fire in an emergency situation.
