A guidance system, particularly for guiding persons to a fire exit under conditions of darkness or poor visibility, comprises tactile guidance elements (3a and 3b) mounted along the walls of the building at a convenient height. The elements may comprise strips of fabric pile where the pile is inclined in a direction towards the fire exit (2). The pile therefore feels smooth when a hand is passed over it in a direction towards the fire exit, but feels rough when the hand is moved in a direction away from the fire exit. In conditions of poor visibility a person may thus find the fire exit by following the "smooth" direction of the strip. Other forms of surface shape or texturing may be employed to give the guidance elements a different feel in opposite directions. |
