A 47-year-old male waste material truck driver (victim) died after he was pinned between a hydraulic ram and a hydraulic reservoir tank. The truck was designed to carry a steel open top box that could be dropped off at a desired location. The victim arrived at a site to drop-off an empty container and pick-up a full container. He backed the truck into the home's driveway and dropped the empty roll-off box near the full container. After placing the empty container in the driveway the homeowner gave the victim a payment check, talked to the victim for a few minutes and then went back inside his house. The victim entered the truck and drove it forward with the rails on which the containers slid still elevated. After driving into the street and moving to the left he backed the truck into the driveway until the rails contacted the full container. He exited the cab and apparently noticed a leak in a hose to one of the hydraulic cylinders that raise and lower the rails. He stepped to a hydraulic reservoir tank located behind the cab and reached behind it with his right hand to close a hydraulic shut-off valve. While he reached to close the valve the rails lowered and he was pinned between a hydraulic ram and the edge of the reservoir tank. About 5-10 minutes after the homeowner had talked to the victim he noticed the truck was still in the driveway. He went outside and discovered the driver pinned against the hydraulic tank. He returned to the house and told his wife to call emergency personnel. Rescue personnel arrived a short time later, removed the victim and pronounced him dead at the scene. MN FACE investigators concluded that in order to reduce the likelihood of similar occurrences, the following guidelines should be followed: 1. employers should emphasize during safety training that employees should never approach a machine that has experienced any type of failure until an assessment has been done by a qualified person to insure that workers can safely approach it; and 2. machine and equipment manufacturers should ensure that all operating controls and devices are located in areas that workers can access without having to place themselves in a hazardous position.
