The injured employee had been using a powered industrial truck to unload a delivery of foam buns coming into the plant. He went to assist the operator of a carousel saw in getting a foam bun to go through the saw. The injured employee got on top of the foam bun which was on the saw table and his hands and knees depressed into the bun. His left kneecap was lacerated by the saw blade as the bun went through the saw. The employee was hospitalized with tendon damage that required surgery.
