On November 07, 1994, a 26 year old maintenance man working for a family-owned street sweeping company died when he was crushed between the frame and container box of a dump truck. When the truck box failed to lift completely, the victim's employer, who was also his father, requested that he check and fill the hydraulic fluid level in the problematic truck. The employer then left the worksite. The victim proceeded with the task, apparently removing the plug from the hydraulic drainage/exhaust housing causing the remaining hydraulic fluid to escape and the unblocked container box to fall. The employer returned approximately one hour later and found his son pinned between the truck's container box and frame. He summoned emergency medical services immediately, and then used a company owned backhoe to raise the container box from his son. As he placed the victim on the ground, municipal fire department personnel arrived and began emergency medical treatment. The victim was transported to an area hospital where he was officially pronounced dead approximately forty minutes following his discovery. The MA FACE Field Investigator concluded, that to prevent similar future occurrences, employers should: 1. Ensure that elevated parts of heavy equipment are suitably blocked from movement while being serviced. 2. Develop, implement, and enforce a comprehensive safety program that includes, but is not limited to, worker training in controlling the health and safety hazards of heavy equipment maintenance. 3. In addition, hydraulic system manufacturers should consider engineering safeguard systems that will prevent worker exposure to hazardous conditions while maintaining the equipment.
