According to NFPA 70E® 110.5(I), qualified personnel must perform a(n) ___ in order to work on exposed electrical conductors or circuit parts that are energized.

• A. job walk
• B. electrical hazard analysis
• C. risk evaluation
• D. job estimate

Answer: (B)

The main idea here is that before anyone works on exposed energized electrical parts, a formal assessment of electrical hazards must be done by a qualified person. This electrical hazard analysis identifies shock and arc-flash risks, determines the proper protective measures, and helps decide things like the necessary PPE, the approach boundaries, and whether the work can be performed energized under an approved permit. This is the best fit because NFPA 70E specifically calls for an electrical hazard analysis to establish safe controls for energized work. Other options aren’t the standard terminology or focus: a general job walk looks at the task rather than the electrical risks; a generic risk evaluation isn’t the specific electrical hazard analysis mandated by the code; a job estimate isn’t about safety controls at all.
