NAICS industry code: 321113

While clearing a jam in the head rig chipper an employee had to remove the chipper's lid. When lifting the lid, it was found that a pin which allows the lid to pivot, was not in place. This caused the bottom of the lid to rotate and roll over the bump stop. The lid then rolled over towards the employee, striking the employee in the left arm and the front of his hard hat. The employee sustained a broken left humerus.
