Abstract: On January 7, 2012, Employee # 1 a 22-year- old male was working as a general laborer at a multi-employer worksite. Employee # 1 picked up a 4-ft by 8-ft sheet of plywood that had been placed over the floor opening. As he stepped forward with the plywood in front of him, he fell through a 42-inch by 72-inch floor opening 12-ft down to the floor below. The plywood was not secured or marked to identify the fall hazard that it was covering. Employee # 1 sustained fractures to four transverse vertebrae. Employee #1 was transported to the hospital and was hospitalized for three days. The accident was reported to the Division by the Fire department.
