Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses (2019 edition), defines an escape routes as a:
|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.'
Escape routes may be protected or unprotected, where an unprotected part of an escape route, is that part which a person has to traverse before reaching either the safety of a final exit or the comparative safety of a protected escape route, i.e. a protected corridor or protected stairway.
Alternative escape routes are: ' Escape routes that are sufficiently separated by direction and space or by fire resisting construction to ensure that one is still available if the other is affected by fire. Note: A second stair, balcony or flat roof which enables a person to reach a place free from danger from fire is considered an alternative escape route for the purposes of a dwellinghouse.'
