What is the NFPA 70E four-step strategy for safe electrical work?

• A. Turn off power, lockout, plan the work, and use PPE.
• B. Turn off power, live work permit, plan the work, document.
• C. Turn off power, permit the work, plan the work, and wear PPE.
• D. Turn off power, live work permit, plan the work, use PPE.

Answer: (D)

NFPA 70E guides a practical, staged way to handle electrical work safely. The first move is to remove the energy source whenever possible by turning off the power. If the work must be performed while the circuit is energized, a live-work permit is required to authorize and document the energized work, including hazards, controls, and procedures. After establishing the authorized approach, you plan the work carefully to coordinate actions, barriers, and safety measures. Finally, you apply the appropriate PPE and protective controls for the identified arc-flash hazard, such as arc-rated clothing, a face shield or helmet, gloves, and any other required gear. This sequence—power off when feasible, use a live-work permit if energized work is necessary, plan the work, and wear the proper PPE—embodies the four-step strategy.
