What is NFPA 70E and what does it require for workers in electrical environments?

• A. NFPA 70E is the standard for electrical safety in the workplace; requires hazard analysis, PPE, proper procedures, and arc-flash safety practices.
• B. NFPA 70E governs only building construction codes.
• C. NFPA 70E is a guideline for chemical handling safety.
• D. NFPA 70E applies only to laboratory environments.

Answer: (A)

NFPA 70E is the standard that defines how to protect workers from electrical hazards in the workplace, including shock and arc flash. It requires performing a hazard analysis to determine the potential arc‑flash energy and then selecting appropriate protective measures, along with implementing safe work practices. Workers must be trained, and an electrical safety program should be in place; when work on energized equipment is unavoidable, procedures like energized work permits are used. PPE must match the identified hazard (for example, flame‑resistant clothing, arc‑rated face/shield protection, insulated gloves), and equipment should be properly labeled with incident energy to guide PPE selection. This standard isn't about building codes, chemical handling, or only laboratory environments.
