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.

Interesting facts:

​

• 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:

​

• Blockages

• Obstructions

• Dirt

• Debris impeding a tight seal
