On 21st July, 2020, a call was received by BAFSA (British Automatic Fire Sprinkler Association) member, Triangle Fire Systems advising the company of a fire break out in a flat, on the 4th floor at 1-133 Garnet Road, Thornton Heath, in London, United Kingdom. The call was a result of the sprinkler alarm signaling the call center.
BS9251 sprinkler system
This building is a sheltered housing and Triangle Fire Systems had, retrospectively, installed a BS9251 sprinkler system supplied by a tank and pump, which was commissioned in December 2019.
Triangle Fire Systems’ engineer attended at the site and the sprinkler head was re-instated
London Fire Brigade attended and forced entry. On entry, they learnt that the fire had been extinguished by the activation of one sprinkler head. It appears the resident was using a bedroom as a prayer room and had left the property while leaving a lot of incense candles still burning. It is assumed that these incense candle sticks were the source of the fire ignition, however, it is still unclear as to what the first item ignited was.
Triangle Fire Systems’ engineer attended at the site and the sprinkler head was re-instated, with the system being made live by 1700 hrs.
Fire sprinkler efficiency and response time
BAFSA (British Automatic Fire Sprinkler Association) noted that a second sprinkler head in the hallway had got hot enough for the cover plate to drop off, but not to activate the sprinkler head, which was a perfect example of how accurate sprinklers are in fire break outs initially. They really do not go off all at once!
