An employee had just finished unloading a shipment of cardboard boxes. The cardboard boxes were on pallets; the individual pallets and stacks of cardboard boxes were secured with banding straps. The employee grabbed and pulled on a banding strap on one of the pallets to try and straighten the pallet by a few inches to align with the other pallets. When the employee pulled on the banding strap, the strap broke and the employee fell to the floor. The employee broke his left hip. The employee was hospitalized for hip surgery.
