What is fire stopping?

The use of rated fire stopping materials tested to BS 476 part 20/22 has been part of standard building specifications for quite some time, but many clients and indeed builders do not realise the potential risk they take by not employing the services of a third party expert in this field to ensure these products are fitted correctly.
When fixed extinguishant systems are installed in an enclosure, it is imperative that the enclosure can affect a fire rated seal and pass an Integrity Test. Fire Stopping is carried out to seal all penetrations that can potentially allow gaseous extinguishant to escape. This would therefore allow the concentration of the gaseous agent to lower and would not ensure that the system can effectively extinguish a fire in the event of a discharge.
