How To Properly Inspect And Test Fire Dampers

Fire dampers are passive fire protection products used in HVAC ducts. British Standard 9999:2017 Annex W.1 gives clear guidance that all fire dampers should be tested at regular intervals not exceeding 2 years and that spring operated fire dampers should be tested every 12 months and at greater frequencies if in a dust-laden environment.
The Ductbusters team are highly experienced in carrying out fire damper drop testing and are more than happy to pay you a visit. As dampers are fusible links for fire dampers metal curtains that shut when heat or fire causes the fusible link to melt, it is vital that this aspect of the damper is fully functional.

In the European designs, the turning mechanism is fully contained, permitting the dampers (subject to type approval) to be grouted in place, which permits a heat sink effect to conduct heat from an accidental building fire, which impinges upon a duct and damper, to be conducted into surrounding structures.
Working Fire Dampers are essential when it comes to stopping the smoke from spreading throughout a building and saving lives, we offer extensive testing services to ensure the Fire Dampers you have in your building will work correctly in the event of a fire.

This guide provides recommendations for the proper commissioning of fire and life safety related dampers and details the appropriate intervals and methods for performing periodic performance testing of these dampers. I just read that NFPAs Standards Council rejected the proposal in April to allow health care facilities to increase the frequency for damper inspection and testing from 4 to 6 years.
There are two main types of fire dampers: dynamic fire dampers and static fire dampers. Fire dampers are designed to close when either their fusible link melts or they are sent an electrical signal from a fire alarm system. A fire breaks out and the temperature reaches 72°C: the fusible link melts and the damper blade closes.
By becoming familiar with the applicable codes and requirements, facility staff will be able to answer questions and ensure building safety. Our ductwork specialists are highly experienced in the maintenance of critical fire safety systems in ductwork. Fire and smoke dampers are an important way to stop the spread of fire and smoke through a building's air conditioning and ventilation duct pathways.
