13. Are electricians and "Qualified Electrical Workers" trained in NFPA 70E safe work practices and authorized to work on specific equipment?

14. Does each employee who is exposed to the hazards of flames or electric arcs wear Arc Rated (AR/FR) apparel and PPE when working on or around exposed electrical conductors?

15. Are all electrical equipment and systems treated as energized until tested or otherwise proven to be de-energized?

16. Does the organization have a written Control of Hazardous Energy (LOTO) Program?
