London Fire Brigade report that just after 2130 hrs on 23 October 2014, an electrical fire started behind some partitioning in a 3rd floor corridor at the premises in Park Lane, London. As the fire developed it actuated the smoke detection then broke out from behind the partition and activated a high pressure mist system in the corridor with 60 persons being safely evacuated.
London fire Brigade mobilised four appliances to the incident and fire-fighters utilised the dry rising main to deploy hose, breathing apparatus teams and a thermal imaging camera to deal with the incident. The fire was extinguished using one main jet
Later fire investigation concluded that the misting system had helped to prevent fire spread by wetting the area in the corridor in the vicinity of the fire.
BAFSA Comment: We have requested more information from LFB as watermist actuation systems are still relatively rare and it is important to see how this system actually operated.
