Orientation signs should be located in accessible places adjacent to, but not directly in, main access routes so that they can be examined without disturbance.
In public buildings there should be an orientation plan immediately inside the main entrance. This plan should follow all relevant design criteria stated in this Part and in B-24.3.
Directional signs should clearly direct people to the facilities. They should be located where directional decisions are made and constitute a logical orientation sequence from the starting point to different points of destination. They should be repeated, not too often, but every time there is a possibility of alteration in the traffic direction.
Directional signage to washrooms should be provided in all parts of a precinct or building.
Stairwells should have information signs identifying all points of entry and exit.
Floor numbers shall be located on each floor at top and bottom of stairs, on handrails and on each side of the outer frame of each lift-car entrance on each floor and prominently displayed elsewhere so they are visible from the lift car at each level.
