Sprinkler Week 2021

We’ve been working with the National Fire Chief’s Council to support Sprinkler Week this week and have been working to make sure people know the facts about sprinklers.

Sprinklers: the myths

Myth: When there is a fire all the sprinkler heads go off at once

Each sprinkler head is independent of the others and only the head closest to the fire go off.

Myth: Water damage is as bad as the fire damage

Where a typical sprinkler discharges around 55 litres per minute. A firefighting hose discharges over 600 litres per minute. You can expect a sprinkler to discharge less than 5% of the water used by the fire service.

Myth: Sprinklers can go off accidentally
Records show that the chance of an accidental discharge from a sprinkler is in the region of 16 million to one.

Myth: Sprinkler Systems are expensive.
It is estimated that the costs of a sprinkler system can be recovered over a period of about 10 years. This is achieved through reduced insurance premiums and in larger organisations through less disruption to business continuity when a fire occurs. Installed in a new building a sprinkler system should not cost more than 1-2% of the total build cost.

Sprinkler: the facts

Environmentally friendly
Sprinklers help to protect the environment by controlling a fire in its early stages, preventing air and water run-off pollution.

Sprinklers save water
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. This is equivalent to three months supply of water for the entire population of a city the size of Leeds.

Building design flexibility
Sprinklers can save on building costs because under Building Regulations larger compartment sizes may be constructed.

Legal protection
Owner/occupiers/employers can be held legally responsible for the consequences of a fire if adequate fire precautions have not been taken. Sprinklers protect the lives of firefighters and are fully supported by fire services.

Easy to install
Sprinkler systems can be fitted into existing buildings. We have installed sprinklers to our Mount Wise Towers while people have continued to live in their homes.

Reliability
Sprinkler systems have been proven in use for well over 100 years, during which time they have a 99% success rate worldwide. Systems over 100 years old are still in full working order today.

Popularity
There are 40 million sprinklers fitted worldwide each year.

Life safety record
In the UK there has never been a fire death in a building with a fully maintained sprinkler system.

Sprinklers save money
Losses from fires in buildings with sprinklers are estimated to be only one tenth of those in unprotected buildings.

Limited Water Damage
Firefighters often use 20 times more water from hoses to do the same job as a sprinkler. In tackling the Windsor Castle fire 7 million litres of water was used.

Cost effective to install
The cost of installing a sprinkler system is roughly equivalent to carpeting the same building. All the UK Royal Palaces could have sprinklers installed for the cost of the Windsor Castle fire.

Insurance discounts
Insurance companies can offer large discounts for buildings that are protected by sprinklers.
