why install a fire sprinkler?

Sprinklers & Buildings Regulations Approved Document B


his document covers all requirements when it comes to fire safety in domestic and residential dwellings.

Installing fire sprinklers designed and installed to BS9251 is one of the easiest and most effective ways of meeting these regulations.

There are a variety of applications that are often accepted by building control officers when sprinkler systems are installed.

Fire brigade access

Building regulations state fire brigade appliances must be sited within 45m of a domestic or residential property and the access roadways must be wide enough and have suitable turning circles available.
Development on land, not meeting these requirements, will be allowed where fire sprinklers have been installed in accordance with BS9251.

Open stairways

Stairways open to ground floor living areas from second floor accommodation, accepted when fire sprinklers have been installed.

Alternative means of escape

Where there is an occupied space over 7.5m, ADB will require a secondary means of escape. This requirement can be waived with the installation of a fire sprinkler system throughout.

Heat detectors

The installation of fire sprinklers will see a relaxation of requirements for heat detectors to be installed in bedrooms or bedsits with cooking facilities and kitchens. Fire sprinklers operate at a similar temperature to heat detectors, meaning the audible alarms are sounded at the same time.

Inner rooms

Inner rooms opening on to an open plan living space are not acceptable under the guidance of ADB but will be allowed with the installation of fire sprinkler or fire suppression system.

Internal protected corridors or hallways

These can be extended where fire sprinklers have been installed.

Travel Distance

Travel distances in bed sits or open plan apartments can be extended where fire sprinklers are installed.
