A non fatal accident occurred recently where a contract employee was performing maintenance on an operating chemical fluid pump, mounted under a Mack delivery truck, when he became entangled in the P. T. O. shaft. The injury resulted in a compound fracture of the humerus bone with avulsions of the muscle tissue of the left arm. A dozer operator walking by the truck to his job noticed the injured entangled in the shaft, ran and shut the truck off, which freed the injured from the shaft.
