At approximately 9:45 AM, a maintenance technician was assisting in removing a feed roller from a coating tank. The bolts were removed and a supporting chain was in place. The technician was using a prybar to unseat the roller shaft when the prybar slipped, causing him to lunge forward and strike the right side of his face against a valve stem. The technician sustained a fracture and laceration to the cheek, and required surgery for an injury related to his right eye. He was hospitalized.
