Which NFPA publication addresses stored electrical energy hazards in electrical safety?

• A. NFPA 101
• B. NFPA 99
• C. NFPA 1
• D. NFPA 70E

Answer: (D)

The main idea is electrical safety in the workplace, specifically how to protect workers from hazards that persist even after a circuit is turned off. Stored electrical energy hazards occur when energy remains in capacitors, springs, or other components after de-energizing, and can release suddenly during maintenance, causing shock or arc flash. NFPA 70E covers electrical safety in the workplace and gives the requirements for energy isolation, lockout/tagout, verification of de-energization, and safe work practices to prevent injury from stored energy.

The other NFPA publications aren’t focused on this particular aspect: NFPA 101 deals with life safety from fire in buildings, NFPA 99 covers electrical systems in health care facilities with a broader healthcare context, and NFPA 1 is the Fire Code addressing fire prevention and general safety rather than electrical safety procedures for workers.
