Some building entrances have several doors in a row, such as theatres and auditoriums. When these doors swing out into the path of travel, they can pose a hazard to people impacted by blindness. A colour-contrasted, cane-detectable safety guard should be provided.

Sets of automatic sliding doors are a better alternative to a row of swing-type doors. Another option is to provide one set of sliding automatic doors in the middle of a row of standard doors at a building entrance.

Where doors are provided in a series, such as in a vestibule, the length of the vestibule should be at least 1,500 mm plus the width of any doors swinging into the vestibule.
