Abstract: Employees #2 and #3, utility company workers, were venting natural gas from a section of a gas main through a 2 in. water suction hose designed for a maximum pressure of 125 lb psi. The gas main contained natural gas at a pressure of 300 lb psi. The hose broke loose from its connection when charged, whipped around, and struck Employees #2 and #3, as well as Employee #1, an inspector. A wire reinforcing the rubber hose amputated one of Employee #1's fingers, and nearly amputated a hand. Employee #1 also sustained lacerations on his arm and face. He was hospitalized. Employees #2 and #3 sustained bruises and lacerations and were treated and released.
