Exit passageway definition
According to approved document B of the building regulations, 'Fire Safety', an exit passageway is:
| A protected passageway connecting a protected stairway to a final exit. |
Where, a protected stairway is a stair discharging through a final exit to a place of safety (including any exit passageway between the foot of the stair and the final exit) that is adequately enclosed with fire-resisting construction.
And a final exit is the termination of an escape route from a building giving direct access to a street, passageway, walkway or open space, and sited to ensure the rapid dispersal of persons from the vicinity of a building so that they are no longer in danger from fire and/or smoke.
The approved document requires that exit passageways are protected to the same standard as the stairway that they serve.
