Abstract: A crew of electricians for an electric utility was performing routine maintenance in a substation. A journeyman electrician and an apprentice were assigned to service 12-kilovolt bus disconnects. The disconnects were not originally scheduled in this job; however, since they were available for servicing, the foreman decided to do them as well. One end of the line (#102) to the disconnects had already been deenergized, locked out, and tagged. the electrician was instructed to deenergize the other end of the line (#101). The electrician was then supposed to service the deenergized contacts at both ends before reenergizing disconnect #101. However, the electrician reenergized disconnect #101 before he serviced disconnect #102. He received an electric shock when his oil squirt can contacted the energized conductor at disconnect #102. He was hospitalized for his injuries.
