Hold the fire

By November 10, 2015News

Part of keeping your ventilation system compliant involves regular testing of your system’s fire dampers in accordance with BS 9999:2008. If you do suffer a fire, your fire dampers should close to help compartmentalise the building and prevent or delay the spread of fire, so it’s essential, as well as a legal requirement to keep them tested and maintained.

If you have a sizable ventilation system in a large building, then you almost certainly have fire dampers. Larger properties are built with barriers in the form of fire resistant walls and doors in order to delay the spread of fire from area to area. Ventilation systems create openings in these barriers in order to allow the free flow and exchange of air, expelling stale air and bringing in fresher air from outside to maintain a healthy indoor air quality. Fire dampers are installed in order to re-compartmentalise the building. These are essentially louvres, installed in fire resistant walls, which will close when fire breaks out.

Unfortunately, accurate records are not always kept of the locations and types of fire damper, and many building managers tell us that they don’t know where their fire dampers are, let alone when they were last tested. Fire dampers should be tested every twelve months or two years according to their type, so if yours have not been tested recently, you’re probably not compliant.

We can locate, identify the type and drop test fire dampers in compliance with BS 9999: 2008, as well as making any repairs or carrying out any maintenance required. Read more about fire damper maintenance here.
