Abstract: At approximately 1:00 p.m. on November 17, 2008, Employee #1 was directed by management to remove the rear utility box from one vehicle and install it to another. The supervisor and Employee #1 did not discuss how the rear utility box would be removed, but agreed the fuel tank needed to be removed first. Employee #1 determined that two straps and the gauge hose located between the filler neck and vent tube hose would have to be removed. The bolts to the straps were severally rusted to the box. Employee #1 used an electrical reciprocating saw to cut the strap on either end. He then requested a coworker assist him and hold up the tank while he cut it. The first strap was removed, and then he cut the gauge hose located between the filler neck and vent tube hose. The only thing holding the fuel tank in position was one strap. Employee #1 continued to cut one end of the strap. The electrical reciprocating saw was directly under the vent tube hose opening that was previously cut. When completing the cut, the coworker was unable hold the tank because of the weight. The tank rapidly fell at an angle that allowed fuel to escape through the vent tube hose and come in contact with the saw. The fuel was immediately ignited from a spark inside the saws housing. Within seconds, the entire truck and building was on fire. Employee #1 sustained severe burns to his leg and was hospitalized.
