Description:On October 3, 1998, a 32-year-old laborer for a boring and tunneling company died when he was struck by a hydraulic hose coupling. The victim was part of a crew digging a tunnel. They were using a hydraulic jacking machine to push 54-inch diameter casing into the tunnel, one section at a time. The victim was standing next to one of the jacks. When pressure was applied to the hydraulic lines, the male end of the hydraulic hose coupling, attached to the jack, split in half, and the connection parted. The sudden release of hydraulic pressure caused the hose to whip and the female end of the connector on the end of the hose struck the victim in the abdomen. The TX FACE investigator concluded that to reduce the likelihood of similar occurrences, employers should: 1. Install straps (whip checks) to the hydraulic hose-ends at the connection points to restrain the lines from whipping if couplings fail. 2. Instruct workers to remain clear of hydraulic hose connections when hydraulic pressure is initially applied. 3. Ensure that relief valves settings do not exceed the maximum manufacturer's recommended working pressure for couplings, hoses and other components of the hydraulic system.
