Power Operations Arc Flash Protection

Due to the risk of personnel injury from arc flash hazards, we performed an evaluation to determine if (1) TVA’s arc flash procedures were being performed as required, (2) required personal protective equipment (PPE) was available and properly maintained, and (3) required training was completed. We determined some requirements of TVA’s arc flash procedure were not being performed. Specifically, we determined (1) some arc flash hazard analyses were not complete, reviewed timely, updated, or verified and submitted for record; (2) some identified arc flash hazards were not communicated accurately to workers; and (3) arc flash hazards were not consistently documented. In addition, we determined arc flash training needs improvement. Specifically, we determined (1) not all personnel assigned arc flash training had completed the training curriculum, (2) TVA’s identified population of individuals required to have arc flash training was incomplete and not a reliable indicator as to who is required by the Occupational Safety and Health Administration to receive the training, and (3) TVA does not require retraining at the frequency suggested by industry guidance. Also, while PPE was generally available and in good condition, PPE management practices could be improved.
