A cooking oil fire in the kitchen of Flat 41 of the 12 storey residential block of 71 flats owned by Birmingham city Council was extinguished by a single sprinkler head actuation within five minutes, probably nearer 40 seconds. This is BS 2951 installation with a pump in the 2nd floor tank room.
Apart from some smoke and water damage, minimal damage was caused. Without the sprinkler this could have caused more serious damage to persons and/or property.
