All facilities should be in compliance with the National Fire Protection Association. This means that all facilities fire and smoke damper be tested. Dampers should be tested and inspected one year after installation. The frequency of testing and inspection should be every four years for commercial properties and every six years for hospitals. Smoke and Fire Dampers should also be in compliance with the HVAC system. Air conditioning and ventilating systems shall be so installed and maintained as to minimize the danger of spread of fire, smoke or fumes from one floor to the other or from outside to any occupied building or structure.
Air conditioning and ventilating systems circulating air to more than one floor or fire area shall be provided with dampers designed to close automatically in case of fire and thereby preventing spread of fire or smoke. Fires spread quickly through the air conditioning ducts. Fire Smoke Dampers and air control dampers are needed for buildings. Fire and smoke dampers play a critical role in not only your life safety systems, but also the HVAC system in your facility. When a damper does not operate and the damper door does not open after a test of the alarm system, the air flow in your facility is altered and causes the balance of the system to change dramatically. This can cause irregular air balance and cause corridor doors to stay open when they should close and can also redirect air flow in the HVAC system affecting temperature stability. If you need to do a fire and smoke damper inspection, AirTek provides commercial air duct cleaning and indoor air quality services. Always exercise fire safety precautions to prevent any fire that can cause loss in property and the life of someone.
