The standard referenced in the contractor responsibilities is which of the following?

• A. NFPA 70E
• B. NFPA 70
• C. OSHA 1910
• D. IEC 60950

Answer: (A)

Electrical safety in the workplace is about having defined practices to prevent shock and arc-flash injuries when work is performed near energized equipment. NFPA 70E directly addresses these safe work practices, training requirements, and administrative controls that contractors must follow. It lays out how to assess hazards, implement protective measures, use PPE, and apply lockout/tagout and other controls to keep workers safe during electrical tasks. Because it focuses specifically on how workers conduct themselves around electrical hazards, it’s the standard most commonly referenced for contractor responsibilities.

NFPA 70, the NEC, is about installation requirements for wiring and equipment, not the day-to-day safe-work procedures contractors must follow. OSHA 1910 covers general workplace safety rules, not the detailed electrical safety practices unique to electrical work. IEC 60950 pertains to safety of IT equipment, not electrical work practices for contractors.
