Abstract: At approximately 10:45 a.m. on January 10, 2006, Employee #1 was changing the phase tape from orange to purple, as requested by a city inspector's list of items to be corrected. He was working on a 480-volt (phase-to-phase) and 277-volt (phase-to-ground) load center sub-panel box. He had pulled the wire out of the de-energized phase "B" of 200 amps and was taping it while holding an Allen wrench key set with his right hand when he somehow contacted phases "A" and "C" on the energized line side of the unguarded meter base. This caused a phase-to-phase dead short that resulted in a flash fire. Employee #1 sustained first- and second-degree burns to his face, neck, ear, and right hand. The Hayward Fire Department was already onsite conducting a fire inspection and immediately responded. Employee #1 was transported to Santa Clara Valley Medical Center, where he was hospitalized for seven days. At the time of the accident, Employee #1 was wearing a cotton red baseball hat, long-sleeved flannel jacket over a short-sleeved cotton t-shirt, blue jeans, safety glasses, and work boots. The key set was not insulated.
