Abstract
An apparatus and system utilized in a storm shelter to notify rescue personnel that a person is in the storm shelter and needs assistance to get out. The apparatus comprises a tubular member, a cap at the upper end of the tubular member, a mechanism at the upper end of the tubing to signal rescue personnel and a mechanism to move the tubular member upward. The signaling mechanism is a light source with apertures in the tubing to allow light to emanate outward, reflective material, florescent paint and/or an audible source. The moving mechanism comprises a threaded rod vertically supported by a base with a threaded nut that rotates on the rod to raise the tubular member or it comprises a lifting mechanism that raises the tubular member. The system has an opening in the upper wall of the shelter and a removable plug apparatus that plugs the opening.
