On August 13, 2008, four electricians were working at a 6,900-volt to 13,200-volt electrical distribution substation restoring service after a squirrel caused an event that blew fuses and damaged insulators. Employee #1 who was located on the substation structure came in contact with a 7,160-volt to ground energized conductor, causing the protective relay for the system to trip. Employee #1 then fell across all three conductors of the circuit. Shortly after contacting the three conductors of the circuit the protective relay reset, energizing the conductor at 13,200-volts, phase to phase. Employee #1 then fell approximately 12 feet to the ground. CPR was performed, but proved to be unsuccessful. Employee #2 received flash burn injuries, but did not lose consciousness. Employee #2 was transported to a local hospital, admitted and treated. Employees #3 and #4 were taken to the hospital where they were examined and released.
