What is the primary purpose of NFPA 70E in electrical work?

• A. Provide safety guidelines to protect workers from electrical hazards, including shock and arc flash.
• B. Establish energy efficiency standards for electrical equipment.
• C. Define wiring color codes for industrial installations.
• D. Set permissible voltage levels for transmission.

Answer: (A)

NFPA 70E is a safety standard for electrical work, focusing on protecting workers from electrical hazards like shock and arc flash. It provides guidelines for safe work practices, hazard analysis, PPE selection, training, and procedures to de-energize equipment or authorize energized work when necessary. By outlining how to plan tasks, assess risks, and choose appropriate protective measures, it helps reduce injuries and fatalities on the job. It isn’t about energy efficiency standards, wiring color codes, or setting transmission voltages.
