A protected stairway should be enclosed with fire-resisting construction and fire resisting doors in order to protect people escaping down the stairs from a fire in the accommodation.

It may not always be necessary to provide fire doors on cupboards if they are small and the fire risk is low. An alternative to providing a fire door on a bathroom is to include the bathroom within the stair enclosure, thus removing the need for a fire door.
