Investigation Summary

On November 13, 2006, Employee #1 received a call on his cell phone from a coworker asking him to find the serial/order number of a 480-volt/three-phase attachment plug so that more attachment plugs could be ordered. Employee #1 found such a plug, possibly choosing it because it was in an idle machine and the only one not in production. Employee #1 accidentally placed the ground prong into the energized plug receptacle and grounded out, causing the third-phase fuse to blow. He was electrocuted. The wiring and the Chicago Pyle/National attachment plug were found to be very dilapidated and had not been inspected or maintained. Because of the configuration of the plug, any of the eight-prong male plugs could have been inadvertently placed in any of the female receptacles, energizing the metal casing. Because of Employee #1's medical condition and the fact that there were no electrical burns inside or outside his body, the coroner considered ruling the cause of death as natural causes/coronary disease. After continuity testing and destructive testing of the evidence, the cause of death was ruled to be electrocution.
