What are Fire Dampers?
A fire damper is a mechanical device, which is operated either manually or automatically, to prevent the fire or smoke from spreading through a ductwork system. Fire dampers are located in the ductwork where it passes through fire retardant walls or floors.
Fire Dampers Inspection
Fire Dampers are a critical part of the fire protection system. Correctly operating fire dampers can make a significant difference in the case of fire. If they fail to close they won’t prevent fire from spreading and that could lead to destruction and death.
It is very important to make sure that the fire damper works properly when fire occurs. Drop testing, cleaning and maintenance of fire dampers is crucial to keep your fire safety system in good condition.
All Clean provides a Fire Damper Inspection which includes:
- creating an inventory of fire dampers in the building
- drop testing
- cleaning the fire damper and applying lubrication if necessary
- addressing running repairs if needed
- inspection will be followed with a comprehensive report and photographic evidence of the performed test
How do the Fire Dampers work?
In most cases a fire damper is held in the open position with a fusible link that melts at 72°C, releasing the blades of the damper to close and stop the fire from spreading through the ductwork.
Smoke control dampers
Smoke dampers are passive fire protection products used in air conditioning and ventilation ductwork. They are installed to prevent the spread of smoke from the place of fire origin to other places in the same building. A combination of fans and dampers can exhaust smoke from a place where fire is presence, while pressurising the smoke-free areas around the affected place. Smoke control dampers are single or multi-blade dampers that would have two safety positions, open to allow smoke extraction or closed to maintain compartmentation.
