Abstract: At approximately 2:25 p.m. on May 14, 2008, Employee #1 was bringing the steam system back on line. He opened two gate valves downstream of the pressure reducer valves on the one-third and the two-thirds systems. When Employee #1 opened the gate valves, the 8-in. strainer on the two-thirds system ruptured which caused steam and condensation to quickly flow into the room. As the room filled with steam and condensation, Employee #1 apparently attempted to exit the mechanical room through the double doors located on the northwest side of the room. Employee #1's body was discovered by the Durham Fire Department behind a large heat exchanger in the mechanical room, between heat exchanger PHWT&P-2 and a cinder block wall.
