Sprinkler System in Shopping Centre Attacked by Mob Contains

'Mark O'Meara from Greater Manchester Fire and Rescue Service reports that on Tuesday 9th August a severe fire occurred in a shop unit at the Salford Centre, Manchester, during the riots that affected the city. The centre manager indicated that the sprinklers activated and although it struggled with the size of the fire it still contained it until FRS extinguished it. The fire was contained to the unit, the centre is still operating.

Greater Manchester Fire Service reported 155 fires across Manchester city centre and Salford during the time the unrest was taking place and so details of the incident are sketchy at present.'  This is an important demonstration that properly designed sprinkler systems will cope with even extreme circumstances and that sprinklers are an effective counter to deliberately started fires.

Hydraulic calculations for Wet & Dry risers systems

A useful research report has been published by ODPM to provide information on the limitations of fire rising mains such as wet and dry risers complying with BS 5306 part 1: 2006.  The report looks at a number of different pumps and nozzle and hydraulic calculates the pressure loss through the pipe.

The Canute - FHC hydraulic calculation software is able to make the same types of pressure loss calculations as presented in this report which may help installers and designs verify designs.

Sprinklers Save Firebombed DIY Superstore, Belfast

The BBC Northern Ireland carried this story on 15 October:

"Police appealed for keyholders to check premises. Police have warned traders in Newtownabbey to be extra vigilant after a firebomb attack on a B&Q store in the area.    The store on Mill Road sustained smoke and water damage after a fire broke out near wood in the DIY section. The sprinkler system kept the fire under control until firefighters arrived at about 2340 BST on Saturday.    

Assistant Divisional Commander Gary Allen of the NI Fire and Rescue Service said the system prevented major damage.    "We went in and found the fire and put it out. When we were looking through the material that had been burning we found one of the devices placed within a quantity of wood," he said.    "Because of the sprinklers in the B&Q premises, the fire was very, very small and we were able to deal with it quickly and stop it spreading."   

 BAFSA Member John McCann of API Vipond says that this is the third such fire and sprinkler stop involving B&Q stores in the province. A similar fire at the DIY chain's premises at Coleraine on Sunday 8th October was also controlled by the sprinkler system.
