What is a fire damper?

A fire damper is a passive fire protection device installed in ductwork or ventilation systems to prevent the spread of fire and smoke through the ductwork.

When exposed to high temperatures from a fire, the fire damper closes automatically to block the passage of flames, smoke, and hot gases. This helps to contain the fire and prevent it from spreading to other parts of the building.

Fire dampers are typically made of fire-resistant materials such as steel or aluminum, and are designed to withstand high temperatures for an extended period of time. They are usually installed in walls, floors, or ceilings where ductwork passes through fire-rated barriers.

Fire dampers are an important component of a building's fire protection system and are required by building codes and regulations to ensure the safety of occupants in the event of a fire. Regular maintenance and inspection of fire dampers are essential to ensure they are functioning properly and will operate effectively in the event of a fire.
