A heavy equipment operator was killed when he was crushed between the lift arm and the rollover protection cage of a skid-steer loader.

NIOSH 2004 Oct; :1-6
An 18-year-old heavy equipment operator died on August 6, 2004 from internal injuries he received after being crushed between the lift arm and the top edge of the rollover protection cage of a skid-steer loader. On July 24, 2004, the decedent was attempting to reinsert a pin that had slipped out of the arm where the bucket was attached. He had lifted the safety lap bar, stood up in the cab, and then pushed the lap bar back down on the empty seat, which allowed the vehicle to run without the operator in the seat. While attempting to move the lift arm up and down to reposition the pin in the arm assembly, the decedent actuated the foot pedal and the bucket moved up and back, pinning the victim between the lift arm and the top edge of the rollover protection cage. Coworkers quickly responded to the victim and removed him from the skid-steer loader. The decedent was transported to the hospital and died 13 days later from his injuries. Oklahoma Fatality Assessment and Control Evaluation (OKFACE) investigators concluded that to help prevent similar occurrences, employers should: 1. Ensure that skid-steer loader operators do not position themselves outside of the operator's compartment while the machinery is in use. 2. Ensure that skid-steer loader operators do not bypass or override safety guards, switches, or devices and properly use seat belts and restraint bars. 3. Ensure that all equipment is secured before servicing and maintenance are performed and that only authorized employees perform that maintenance. 4. Ensure that employees are aware of the specific hazards and limitations of the equipment they use and work around on job sites.
