Employee injured when struck by cap of water line

Investigation abstract

Employee #1 was going to remove a 6 inch cap from a 6 inch pressurized water lin e so that a valve and fire hydrant could be installed. When he removed one of th e wing nuts from one of two all-thread bolts that held the cap in place, the cap blew off, fracturing his chest. He was hospitalized. The employee had worked on another 6 inch line on the main line two days before, and had tested that line before working on it to see if it was under pressure.
