The specifications provided in the section Exterior Doors are equally applicable to doors within a building. This section provides additional specifications for interior doors.
Doors accessible from the path of travel should either be recessed or open into rooms to avoid obstructing the path of travel. Entranceways without doors can also provide access, negating the potential hazard of door swings.
Open doors in halls and corridors are a serious hazard for people impacted by blindness. Wherever possible, avoid having double doors where only one side opens. Either both doors should be propped open or both doors should be shut. This will prevent people impacted by blindness from inadvertently encountering a partially open door.
Signs to identify rooms should be located adjacent to the latch side of doors. Further information is provided in the signage section.
Raised thresholds should be avoided wherever possible. If they are required, thresholds should be no higher than 13 mm. Thresholds higher than six millimetres should be bevelled. All thresholds should contrast in colour and brightness to their surroundings.
