A 35-year-old white male facilities journeyman electrician (victim) was electrocuted while doing electrical maintenance work on a power mound (transformer) in a shipyard. The power mound provided power to numerous essential power activities including shipboard activities, confined spaces, lighting, and power handtools. The incident site (south power mound) was located outside in the southern portion of the shipyard. This area was wet due to rain on the night of the incident. The maintenance work the victim was doing that evening exposed him to high electrical voltage (12-thousand kilovolts and 600 amps). There was no ground provided for the power mound at this location. The victim was not using any personal protective equipment (PPE). The California FACE investigator concluded that, in order to prevent similar future occurrences, employers should: 1. have an Injury and Illness Prevention Plan (IIPP) which addresses electrical safety training for supervisors and employees working with electrical equipment. 2. have an standard operating procedure (SOP) that states that all high voltage work be done by a licensed electrician. 3. have a proper ground in place for all electrical power mounds and equipment. 4. have a standard operating procedure (SOP) which addresses the procedures for a lockout/tagout system. 5. have all power panels and mounds (transformers) labeled so that it is evident where electricity is provided and from which panels. 6. train employees in the proper use of personal protective equipment (PPE). 7. have a standard operating procedure (SOP) which addresses the necessary environmental conditions for certain types of work activities, such as high voltage electrical work. 8. have a standard operating procedure (SOP) stating that there be an employee (either a qualified electrician or an employee in training) located within a short distance of any employee working with high voltage equipment in case of an emergency.
