Abstract: At 11:15 a.m. on July 16, 2008, Employee #1, and a coworker were working at a gas well location in preparation for a tubing operation. Before starting this tubing process, the gas well needed to be relieved of internal pressure. This was done by blowing down the well. A flow line was attached and directed to the waste water pit adjacent of the well. As Employee #1 open the valve necessary for relieving the gas well pressure, the well casing failed. This failure resulted in Employee #1 being struck by the valve and flow line. He was thrown backwards for approximately twelve feet. Employee #1's was taken to a nearby medical facility, where he was hospitalized and treated for multiple fractures and severe internal injuries.
