Narrative
On 08/23/2016 a contractor crew was installing pig trap equipment and associated piping at white lakes station. At approximately 19:45 a popping sound was heard and smoke was seen escaping a tor. The flash fire was completely contained within the pipe and was never visible. Prior to the flash fire occurring, zero lels were detected inside the pipe at the work site. 2/14/2017 upon completion of the investigation, it was determined that vapors were present at a low point downstream, residual product, of where the hot work was being performed. Sparks from the hot work traveled to the downstream low point and ignited the residual vapors. 7/3/2018 incident investigation indicated that contractor failed to adequately follow safety policy. Construction tasks were not DOT covered tasks therefore no DOT drug testing was required.
