Abstract: At approximately 10:51 a.m. on May 19, 2007, Employee #1, a welder, was repairing a diesel fuel tank that had an 88-gallon capacity, L-shaped, welded steel fuel tank labeled "Diesel Fuel Only." It was located in the bed of a 2007 Ford F-350 pick-up truck, bearing license plate Number 8G21478. The truck was backed into the southern most mechanics bay at the entrance to the welding shop. Employee #1 had cleaned the surface of the tank with a grinder to prepare for the weld and had completed three tacks with a Lincoln Power Mig-255 welder; Serial Number K16931 10563 U1000 926694, when the tank exploded. Employee #1 was thrown off of the back of the truck and sustained severe blunt force trauma to his face. He was transported to a nearby hospital, but pronounced dead on arrival.
