When working near energized power lines where the crane or load could cross the absolute limit of approach, what additional requirement must the crane team follow?

• A. Designation of a spotter to watch clearances
• B. Increase the lifting speed
• C. Ignore if wind is calm
• D. Use larger hooks

Answer: (A)

Working near energized power lines, the risk of the crane or load crossing the absolute limit of approach is high, so an additional safety step is needed: designate a spotter to watch clearances and guide the operator. The spotter provides continuous visibility of the boom, load, and any line sag, communicates in real time with the operator, and can stop or adjust movements to keep everything outside the dangerous zone. This setup helps ensure the operation stays within safe distances even as angles change or wind shifts the load. Increasing lifting speed, ignoring conditions when wind is calm, or using a larger hook does not address the essential need to monitor and maintain proper clearance from the lines.
