NFPA 80, NFPA 101 requires Fire Dampers, Rated Doors and Barriers to be inspected and maintained to save lives. These passive systems are in place to extend the chances of people exiting safely from a facility that is under a fire condition. Without the proper program in place to maintain these systems. A facility would be at risk of failing their staff members, as well as anyone who is present in the building during fire situations.
There are three types of dampers associated with the passive and active containment system.
First, there are fire dampers. Fire dampers come in more then a few different types, but all have one common theme. They are equipped with a fusible link rated to burn at 165 degrees. This dampers primary function is to stop the spread of fire.
Second, there are combination fire/smoke dampers. These dampers operate as a passive damper and active damper. The active component is controlled by the fire control panel and is operated with an electric or pneumatic actuator. These dampers can also be equipped with a fusible link or a thermal link to be activated when the temperature reaches 165 degrees. They function to stop the spread of fire and smoke.
The third type of damper is a smoke damper. Smoke Dampers are single or multi-blade dampers that would generally have two safety positions, open to allow smoke extraction, or closed to maintain compart integrity. Smoke Dampers are controlled by an actuator that is connected to the fire control panel. Smoke is the biggest killer when it comes to fires.
Codes for inspections are governed by many different authorities. Each authority will have their own codes to follow, but all stick to the same basic guidelines outlined in International Building Code and NFPA 80.
An operational test must be completed after the installation of the fire damper is complete. Then, each fire damper must be tested and inspected one year after the installation. After that one year mark, fire dampers must then be tested and inspected every four years except for hospitals which have a six year frequency.
Most would expect provisions related to hospitals to be more restrictive than for other types of buildings. The healthcare industry presented the technical committee with significant evidence that a four-year inspection frequency for fire dampers in hospitals, in these buildings, is a hindrance. Hospitals are unique in that they have many building systems critical to the life safety and health of their occupants (patients). Personnel accessing fire dampers every four years would entail the risk of interfering with or potentially damaging the many systems (HVAC, medical gas systems, sprinkler piping, electrical systems) that are located near the fire dampers and above ceilings. The six-year frequency allows for a reasonable but safe length of time between inspections and also ensures the integrity of the hospital operations.
