Abstract
Abstract A light, compact safety tracer carried by fire fighters comprising a novel attaching means for attaching an elongated cord to an object outside or at the entrance of a burning house or at the entrance to a room before a fire fighter conducts searching. As the fire fighter enters the house the fire retardant cord is extended out from the safety tracer clipped on the waist belt of the fire fighter. From the color code on the cord the fire fighter can tell how far he has gone inside. The attaching means is shaped as a wedge so if attached to the hinge of a door it will keep the door open. A light source on the attaching means informs other fire fighters that the room is being searched and a fire fighter is inside. The safety tracer is equipped with a pager so he can alert other fire fighters if he needs help or is in trouble. The extended cord will serve as a guide so even when the smoke is so thick that a fire fighter can not see through he can still easily and quickly find his way out. A slide razor is further mounted on the safety tracer in case the cord is caught to something and the fire fighter has to cut it off.
