Internal circulation
Internal corridor headroom
- The clear height for headroom in pedestrian areas should be a minimum of 2100 mm above the floor.
- Where the headroom of an area that adjoins an accessible route is reduced to less than 2100 mm, a detectable guard, guardrail or other barrier is needed
- The guard should be firmly fixed, colour contrasted & have solid or horizontal railings
Internal corridor obstructions
- outward doors to be recessed to at least width of the door.
- fixtures such as radiators, pipes and ducts to be recessed whenever possible.
- minimum width a corridor should not reduce to when outswing doors enter space.
- Where overhanging or protruding elements on freestanding objects are between 650-2100 mm above the ground, they should not encroach more than 300 mm into pedestrian areas.
Floor Obstructions
- Corridors should be unobstructed along entire length. Items that protrude into circulation space should be recessed outside of corridor path.
- Corridors should be wide enough to allow people to pass each other and turn 180 degrees.
Wall Obstructions
- The leading edge of any protruding object found between 650-2100 mm above the ground should not extend more than 100 mm into pedestrian areas.
- An object with a leading edge at or below 650 mm from the ground may protrude any distance.
