A laborer for a boring and tunneling company in Texas, died when he was struck by a hydraulic hose.
NIOSH 1999 Mar; :1-3
On October 3, 1998, a 32-year-old laborer for a boring and tunneling company died when he was struck by a hydraulic hose. The victim was part of a work crew digging a tunnel and inserting a 54-inch casing. They were using two hydraulic jacks, laid horizontally and connected by hydraulic lines. The jacks were used to push the pipe into the tunnel one section at a time. The victim was standing next to a hydraulic jack when pressure was put to the hydraulic line. The male end of the coupling, attached to the jack, split in half. The female end flew up and 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 and the point where the hose is connected. 2. Instruct workers not to stand adjacent to hydraulic hose connections when hydraulic pressure is initially applied. 3. Ensure relief valves are set so they do not exceed the maximum pressure recommended by the manufacturer for couplings, hoses or other equipment connected to the pump.
