Inspection / Evaluation
Description
The Office of the Inspector General determined some requirements of the Tennessee Valley Authority’s procedures related to arc flash protection and engineering calculations were not performed. Specifically, (1) some arc flash hazard analyses were not performed, (2) arc flash hazard analyses were not periodically reviewed, (3) some arc flash hazard analyses were incomplete or inaccurate, and (4) some hazards were not accurately communicated on warning labels as required. In addition, we found arc flash hazard calculations were not formatted, approved, or maintained as required. We also determined personal protective equipment was maintained and most training was completed as required by the arc flash procedure; however, we identified a few individuals who had not completed the assigned curriculum. Lastly, we identified an opportunity for improvement related to developing a Transmission and Power Supply specific arc flash procedure. Based on issues identified during the course of our evaluation, Transmission and Power Supply performed an assessment of its arc flash program and developed an action plan to address identified gaps.
