Investigation Summary

Investigation Nr: 170081368

Event: 07/17/1995

Employee killed when struck by hammer union fitting

Employee #1, a floorhand, was on the drill floor of an oil well drilling rig replacing a pressure sensor. A pressure sensor measures the hydraulic pressure of drilling fluid in a standpipe. The pressure sensor was attached to the standpipe by a 4 in. diameter hammer union. Employee #1 removed the broken pressure sensor, and replaced it with another one that had a similar (female) hammer union fitting attached. Apparently the threads were not compatible and, when the standpipe was pressured to approximately 2,000 psi, the hammer union blew apart, causing Employee #1 to strike his head against the derrick leg. He sustained multiple fractures and was killed.
