Means of escape
Requirement B1 of the building regulations requires that when there is a fire, there is both:
- Satisfactory means of sounding an alarm.
- Satisfactory means of escape for people.
Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses, defines ‘means of escape’ as:
‘Structural means that provide one or more safe routes for people to go, during a fire, from any point in the building to a place of safety.’
The approved document defines an escape route as ‘The route along which people can escape from any point in a building to a final exit.’ where a final exit is ‘The end of an escape route from a building that gives direct access to a street, passageway, walkway or open space, and is sited to ensure that people rapidly disperse away from the building so that they are no longer in danger from fire and/or smoke.'
NOTE: Windows are not acceptable as final exits.
The approved document sets out ways that means of escape can be provided in commonly-occuring situations.
