An employee was de-energizing a stand-alone three-phase 3,000-kVA transformer. The employee had opened a bay on the switchgear and removed the barrier board covering a 200-amp switch. The employee then used a 6-foot insulated work stick to open the fuse door. As soon as the top of the fuse door separated from the gear's switch bracket, an arc flash occurred, burning the employee's left ear, neck, and cheek area and causing swelling on the employee's lips.
