Description:On Nov. 23, 2003, a 45-year-old construction worker was killed while operating a rock crusher. The operator used a pry bar in an effort to loosen a rock jam in the intake chute, while the equipment was operating. The pry bar made contact with the impactor and was thrown out with great force, striking the operator in the neck. A coworker dumping a load of rock onto the conveyor of the crusher noticed the victim missing from his normal position and spotted him slumped in the corner of the lower platform. The victim was bleeding profusely from the neck, with the pry bar in his lap. Efforts to stop the bleeding were unsuccessful. The victim died at the scene. Recommendations: 1. Never attempt to remove jammed material while machinery is in operation. Shut down, isolate, and block all hazardous energy before performing machine maintenance. 2. Do not allow employees to position themselves directly over the intake of a horizontal impactor while it is actively crushing rock. 3. Manufacturers should consider designing and installing viewing decks where workers can safely access the equipment to observe operation.
