An employee was assisting his co-worker to brace the products (35 inches high by 29 inches wide by 120 inches long) on the forklift. The forklift driver set the double pallet of reinforcement material on to the floor and the forklift backed out. Part of the bottom pallet on the left side broke and the materials started to wobble. The injured employee tried to stabilize it, but part of the top pallet fell on his chest causing him to fall down. As he was bracing his fall, he fractured his left wrist.
