FIRE & SMOKE DAMPER TESTING & INSPECTION
Fire and Smoke Dampers are located in ductwork where it passes through a fire compartment barrier (fire rated floors or walls). They are designed to close when a specified temperature limit or fire/smoke condition is met, preventing the spread of fire and smoke throughout the premises.
Fire dampers play a crucial role in a building’s fire safety system. If they do not operate as designed fire can spread at a rapid pace, resulting in loss of life.
15 minutes of straight smoke (0% oxygen) would kill you
5-10 minutes would cause permanent brain damage
Once you start to inhale smoke, your body is not getting enough oxygen to live, so depending on the density of heat and smoke, it may take 2 to 10 minutes to lose consciousness or die.
The difference between a well-maintained, working fire damper and an ill-maintained, partially working fire damper can be the difference between life and death in the case of a fire.
Typical problems include:
Debris impeding a tight seal
