An employee was supervising as two coworkers removed a plow from an overhead conveyor line. The plow was suspended from the conveyor by two j-hooks and two s-hooks. The coworkers were using a forklift to lower the plow to the ground. As the plow was being raised by the forklift, one of the coworkers guided it so that the mouth of the plow rested on the tines. The tines on the lift were wet due to rainy weather conditions, causing the plow to slide toward the end of the tines and fall off the forklift onto the ground. During its descent, the plow struck the employee on the right side of his body and sent him backwards into a hook rack, fracturing his ribs, shoulder blade, and T-12 vertebra.
