Fire Dampers and Smoke Extracts

Fire Dampers and Smoke Extracts

Fire Dampers

Fire Dampers are classed as passive fire protection products which are installed into heating, ventilation and air conditioning (HVAC) ducts to prevent the spread of fire within the ductwork through fire-resistance rated walls and floors.

Fire Dampers should be maintained on at least an annual basis by a competent person in accordance with BS 9999: 2017. For fire dampers located within dusty environments then testing may be required more frequently.

During a service visit the fire dampers will be numbered and cross referenced within service reports which will identify the type and mechanism of damper along with sizes. All reports contain photographic evidence of the dampers opened, closed and defects. Comprehensive remedial works based on the report can be completed if required.

 

Smoke Ventilation and Extraction Systems

Smoke extract and ventilation systems are designed to control and vent smoke from escape routes such as corridors, lobbies and staircases. Controlling smoke should a fire occur in your building will aid the survivability and evacuation of occupants. In the event of a fire, Automatic Opening Vents are triggered to open high level smoke vents and lower-level air inlet vents. This action allows cool air into the building which forces hot air and smoke through the roof. The requirement to install smoke ventilation systems into buildings is steered by Building Regulations Approved Document B.

Smoke Ventilation and Extraction Systems need to be serviced on at least an annual basis in accordance with BS 7346: Part 1: 1990, BS 9999:2017 and BS-EN 12101. The frequency of maintenance will depend on the type of building and environment.
