There is a legislative requirement (requirement B1 of Approved Document B (ADB)) that specifically addresses the fire safety precautions which must be adhered to, to ensure the safety of occupants, firefighters and those close to the building in the event of a fire.

The extent to which any of these measures are necessary is dependent on the use of the building, its size and its height. Building work and material changes of use subject to requirement B1 include both new and existing buildings.

Further reading and information can be found in our pocket guide to Stairwell AOV’s.
