Abstract: Six employees working for three different contractors were cementing and inspecting steel pipe in three pipe racks. One of the racks was under a 4600-volt overhead power line. The employees were using a truck-mounted crane to load and unload the pipe. As he was moving a pipe from the rack under the power line to a trailer, the crane operator swung the raised boom into the power line. Two employees who were holding steel spreaders hooked to the load line received electric shocks. They released the spreader, and it contacted the pipe rack. Two other employees, who were working on the pipe, and a fifth employee, who was inspecting the pipe, also received electric shocks. All five employees were transported to a hospital. One of the employees holding the spreaders was hospitalized for his injuries. (The remaining four injured employees were not listed on injury lines on the original form.)
