Which standard governs electrical safety in the workplace, including PPE requirements for arc-flash hazards?

• A. OSHA general industry standards
• B. NFPA 70E
• C. NEC
• D. IEC 60364

Answer: (B)

NFPA 70E defines electrical safety in the workplace and sets the requirements for arc-flash PPE and safe work practices. It provides how to perform hazard analysis, determine incident energy, establish arc-flash boundaries, and choose the appropriate PPE—such as flame-resistant clothing, arc-rated face protection, gloves, and footwear—based on the level of risk. It also requires training, procedures, and ongoing safety programs to minimize exposure to electrical hazards. While OSHA enforces workplace safety and commonly relies on NFPA 70E as the practical standard of practice, the detailed arc-flash PPE rules come from NFPA 70E itself. The NEC focuses on design, installation, and operation of electrical systems rather than worker PPE for arc-flash hazards, and IEC 60364 addresses electrical installations in international contexts without specifying U.S.-style arc-flash PPE requirements.
