Passing places in long corridors and passageways
Corridors or passageways longer than 50 m with unobstructed width less than 1800 mm must have passing places spaced at no more than 50 m intervals, each at least 1800 mm wide and 1800 mm long.
Where a corridor or passageway is more than 50 m in length and has an unobstructed width of less than 1800 mm, it should have passing places spaced at not more than 50 m. Every passing place should be not less than 1800 mm wide and not less than 1800 mm long. The width of the passing place may include the width of the corridor or passageway and may be incorporated into corridor junctions.
