<p>An emergency evacuation system displays a visual evacuation route command to an observer during a fire or other emergency and consists of an elongate member such as an adhesive tape, a fluorescent tube or rod or a skirting board, which is fixed to the wall or floor adjacent their junction, and exposed luminous or illuminable direction indicating means displayed by the member. The indication means may consist of arrows which are themselves luminous or are disposed as non- luminous indicia on a luminous background. The system may employ an elongate element in the form of a skirting board length 1 of extruded plastics materials, a channel 3 in the extrusion containing a bundle of optic fibres retained by panels 4 of laminated construction and formed with an outer transparent skin overlying an inner opaque skin formed with a series of cut-outs 6 each of arrow shape and exposing the fibre bundle to view at points along its length. A remote light source illuminates the fibre bundle so that the cut-outs 6 are illuminated to provide a direction indication visible in an emergency situation when reduced visibility may prevail. Alternatively optical fibres may be sandwiched between the two laminae of a laminated tape. <IMAGE></p> |
