Doors and doorways must let everyone, wheelchair users above all, enter and leave any room unaided. A door (one leaf of a pair counts) opens to at least 800 mm clear between the open leaf and the opposite jamb; an unobstructed area is kept beside the handle on the leading face, and a door within 330 mm of a room corner swings from the side nearer that corner; a double-action self-closing door has a check against over-swing and a transparent vision panel spanning from no higher than 1000 mm to at least 1500 mm above the floor; handles sit 950 mm to 1050 mm above the floor at the top of the grip; thresholds are bevelled and no higher than 20 mm; closers let exterior doors open with no more than 30 N and interior doors with no more than 22 N (30 N for fire-rated doors on accessible routes), interior closers taking at least 3 seconds from 70 degrees open to 75 mm from closed; frameless glass doors carry prominent markings across the glass; and the listed public and commercial building types (stadia, town halls and civic centres, theatres, museums and public libraries, shopping, sports and public swimming pool complexes, office buildings, hotels and hospitals) must have an automatic door at one of the main entrances the public commonly uses. The Best Practice Section favours automatic sliding doors and hold-open devices.
