An employee was on a barge positioning the barge cover that was being placed by the ship's gear crane. The cover was not straight so the employee tried to straighten it and was struck from the mid-chest upward by the barge cover. The employee sustained a right anterior fracture of the first and second ribs, a left mandibular fracture, left hyoid fracture, bruising to the left side of the neck and a small pneumothorax.
