Abstract: On April 21, 2007, Employee #1 was disconnecting wiring for two temporary lighting circuits for a building expansion project at an existing business. He was later found, unconscious, laying on the floor in front of the open box. He was transported to the hospital, where he was pronounced dead. An autopsy revealed that Employee #1 had first-degree burns on the back of his left hand near the thumb and on his right lateral chest, consistent with electric shock. It also showed petechial hemorrhaging consistent with electrocution. In addition, he fell to his right and sustained a severe bump on the forehead. Employee #1 did not de-energize the panel before removing the cover and the dead front, although the disconnecting means was about 10 ft. to Employee #1's right. The accident occurred on a Saturday when the rest of the plant was not working. There were no eyewitnesses to the accident.
