ABSTRACT:
A fall restraint system protects a worker while inspecting and/or repairing a roof of a building. The restraint system includes a ladder that is positioned against the building. A fall restraint device is removably connected to the ladder and contacts the roof. A cable support structure is connected to the fall restraint device, and a cable is attached to it. The cable extends from the cable support structure toward the peak of the roof, and from the peak toward the ground. The cable is adapted to be connected to a harness that is worn by the worker. The worker then uses the cable to inspect/repair the roof.
