NFPA-70E focuses on safeguarding electrical workers. Which item is NOT a focus of NFPA-70E?

• A. Arc/flash and shock protection.
• B. LOTO procedures.
• C. PPE requirements.
• D. Wiring color codes.

Answer: (D)

NFPA 70E is about protecting workers from electrical hazards by defining safe work practices, how to control exposure to arc flash and shock, how to isolate energy sources, and what PPE is required for different tasks. The items that are clearly within its scope are practical protections: arc flash and shock protection describes the protective measures and limits for exposure; lockout/tagout procedures are the primary controls to ensure circuits are de-energized before work; PPE requirements specify the gear workers must wear to survive expected incident energy. Wiring color codes, however, belong to installation and identification standards that guide how electrical systems are built and wired, a domain governed by the NEC and related codes rather than the safety practices NFPA 70E prescribes for working on energized equipment. So the item about wiring color codes is not a focus of NFPA 70E.
