Abstract: On April 9, 2004, Employees #1, #2, and #3 were plugging a well. They were working as part of a six-man crew. While they were plugging the well, natural gas from the well head reached an ignition source. A flash fire occurred and several explosions, where the fire reached pockets of gas. Employees #1, #2, and #3 were hospitalized and treated for severe burns. The accident investigation attributed the flash fire and the follow-on explosions to the weather conditions, as well as static electricity produced from the transfer of raw petroleum from the well head to a tank truck through a rubber hose without ensuring grounding.
