Employees were working to re-install a 500-pound shear cylinder (20 x 40 ). They took the cylinder off a pallet and laid it vertically on the ground. Using nylon straps, they rigged the cylinder through eyelets to lift it with a forklift and place it back in the machine. The injured employee grabbed the cylinder and went to rotate it. The cylinder tipped over and landed on the injured employee's leg, fracturing bones in their lower leg and foot. The employee was hospitalized and required surgery.
