Investigation Summary
At approximately 7:25 a.m. on December 1, 2008, Employee #1, a fire protection system contractor, and a coworker had turned off the main building backflow valve and drained the entire complex fire water system. The employees removed blanks on two sections of pipe and installed fillings. In order to install a filling in the third section of pipe, it required that the employees collect and move all their tools and fitting into the complex parking lot. Unknown to the employees, the fire main system repressurized. In order to access the third pipe blank Employee #1 climbed onto a 6-ft ladder, and while directly facing the pipe blank, started removing the flange bolts. Suddenly, the flange blew off striking Employee #1 on the forehead and knocked him off the ladder. Employee #1 suffered a laceration to his forehead and skull fractures. Employee #1 was hospitalized.
