Fatality Assessment and Control Evaluation (FACE) Report for Wyoming: Pressure Tester Struck by Bull Plug in Wyoming, FACE-92-WY-007.

摘要

A 30 year old male oilfield pressure tester died at the scene of an oil rig where he was conducting a pressure test when a bull-plug dislodged from a flow-back manifold, striking the victim in the head. The victim was testing well pressure, and was in the process of releasing pressure from the pressure manifold into the burn pit when the cap came loose under 10,000 psi pressure. The victim was knocked to the ground, his hard hat was thrown 30 yards away from the victim, and the pressure plug shot 200 yards beyond where the victim lay. The nearest witness to the incident was approximately 10' to 15' away, and facing in the opposite direction when he heard a pop, followed by the sound of pressure blowing off. He turned and saw the victim on the ground with severe damage to his head. The witness used a cellular phone to call for help. The victim apparently died within seconds of the incident.
