Abstract: At approximately 10:55 a.m. on June 6, 2005, Employee #1 was pulling wire for a live 480 volt electrical panel at a manufacturing plant. While he was approximately 5 to 8 ft from the panel, an arc flash occurred. Employee #1 was hospitalized for face and upper body burns. The investigation was unable to establish if the incident was caused by pulling wire from the conduits of a live panel or from falling metal shavings causing a short circuit in the panel wiring and/or breakers. The metal conduit housing the wires had been cut by a subcontractor working in the same building during the same time period.
