On March 3, 2009, at approximately 1:29 p.m., Employees #1 and #2 were conducting a gas line pressure test on a 20-inch gas line.
The test involved pressurizing the line to 100 psi and holding this pressure for one (1) hour.
This test was conducted to determine whether the gas line being tested could be reused or needed to be replaced.
During the test, the pipe failed under the pressure.
The two employees conducting the test in the excavation were injured. Employee #1 was killed. Employee #2 was critically injured.
