Stairways need to be clearly marked and easy to find without posing an unnecessary danger. Place stairways near main circulation routes so that they are accessible. They should also be offset from the direct route of travel to reduce hazards. The top of a stairway should be identified with an attention TWSI.

In a building with more than one level, stairways should be placed consistently in relation to other repeated building elements (e.g., always across from drinking fountains or washrooms). Stairs should not be placed in unexpected locations, which could easily disorient a visitor with blindness.
