A device is described which provides egress for persons trapped in burning buildings. The invention comprises a portable supportive base structure having attached thereto a plurality of interconnected channel members which are manually extended to reach the upper levels of multi-storied buildings wherein trapped victims of fire may be located. Winches attached to the device enable an operator to position the extendable members in front of an upper level window whereupon the person being removed enters a personnel receptacle attached to the terminal end of the final extendable member and is thereupon lowered safely to the ground.
