Abstract: At approximately 1:30 a.m. on November 9, 2007, Employees #1 and #2 were replacing a bird switch to a transformer in an underground electrical service vault. The switch flashed, giving Employee #1 second degree burns to the face and blisters to the eyes and Employee #2 superficial burns and facial abrasions. Both employees were taken to a local hospital. Employee #2 was released later the same day. Employee #1 was transferred to the Grossman Burn Center in Sherman Oaks, California, where he was hospitalized. NOTE: The narrative does not say that Employee #2 was hospitalized, but the injury lines in the IMIS summary does.
