ABSTRACT:
A tape marking system used to mark the proper direction of escape during an emergency. The tape has extending fibers oriented at about 45 degrees from a supporting backing layer to provide a smooth to the touch feeling surface in one direction and a rough to the touch surface feel in the opposite direction. By associating one of these feel sensitive surfaces with the proper direction to travel in an emergency, usually the smooth surface, the marking tape even if visually not seeable can be used to lead a person by feel to safety. An adhesive backing on the backing layer allows the layer and its fibers to be applied about light switch height along the length of the passageway to be followed to safety. Exposed indicia, like words combined with symbols, in center of the backing surface can be used to visually inform a user of the desired direction to travel beforehand. This tape strip can be used in buildings, airplanes, trains, boats or any other structure having a passageway to an escape exit.
