Sprinklers operate once the temperature hits approximately 68ºC.
The likelihood of a sprinkler operating accidentally is estimated at 16 million to one – you’ve more chance of winning the lottery!
Firefighters often use 10 times more water from hoses to do the same job as a sprinkler. This increases considerably with larger buildings or commercial premises - in tackling the Windsor Castle fire, 7 million litres of water were used!
Statistics show that widespread use of sprinklers could save up to 96% of the 5.6 billion litres of water used annually in the UK to fight large fires - three months supply of water for the entire population of a city the size of Leeds!
Losses from fires in buildings protected with sprinklers are estimated to be only one tenth of those in unprotected buildings.
More than 40 million sprinklers are fitted worldwide every year.
In the UK there has never been a fire death in a fully sprinklered building. US Government employees on business only stay in sprinklered hotels because the Government will not otherwise pay their expenses.
