Abstract: Employee #1 and two coworkers were removing flooring from a 20 ft by 24 ft overhead storage area during demolition of the area to make room for offices. The flooring was 1 1/4 in. thick plywood sheets, 4 ft by 8 ft, bolted to steel I-beam joists. The bolts had been removed, and the pieces were being stacked on an outside edge of the structure to allow them to be moved by a forklift. A piece of unsecured plywood had been laid across the joists in the stacking area for employees to walk on during the stacking process. The loose sheet became dislodged from the support joist on one end. Employee #1 stepped on that end and fell 10 ft to the concrete floor. The sheet of plywood then fell on top of him. Employee #1 was hospitalized and underwent surgery but he died on March 6, 1993 as a result of his head injuries.
