Fire and Smoke Dampers are passive fire protection products designed to close when temperature rise to prevent spread of fire or smoke inside the ductwork. They are mostly used in ventilation or air-conditioning ductwork.

A fire damper is typically curtain style that immediately shuts down when fusible links starts melting. So whenever there is a rise in temperature it will close automatically which will help flame not to spread through the barrier.

At the time of installation of Fire damper, an operational test is needed to be conducted to verify that the damper operation is not obstructed and there is full access to the damper and all its components. It is also needed to verify all devices work and report to the intended location and these entire tests is to be documented consisting location of the damper, date of inspection, name of the person done inspection, deficiencies found in the damper and their correction details.

Each damper needs to be tested and inspected after one year of its installation and then every 4 years. In hospitals it should be tested every 6 years. During this test some things are ...
... necessary to be checked like –

- There should be no rust, damaged frames or blades, defective parts when the inspection is being done.
- Fusible links should be removed before inspection to ensure full closure and lock in place if required. If that fusible link is damaged then it is necessary to replace it with the link of same size, temperature and load rating.
- The damper should be not blocked from closure.
- The track of damper should be cleaned and lubricated to ensure proper sealing of it.
- The latch, if provided should be checked properly.
- The inspection details should be documented properly.

Other requirements which should be taken care of at the time of inspection are tests should be conducted on standby power if necessary and smoke management systems need to be operated for each sequence in the current design criteria. Fire dampers should be inspected properly to make sure that there are no problems occurring.
Inspection and good maintenance of these dampers is very necessary to ensure that it works properly during fire and life safety event where it should actually act properly so that when the unexpected event happens, the system should be ready.
