The correct choice reflects the regulations set forth by OSHA regarding the safe operation of cranes near power lines rated at 50 kV or below. Specifically, OSHA 1926.1408 establishes that the minimum clearance requirement is at least 10 feet, provided that encroachment precautions are implemented. This means that when cranes operate within this 10-foot range of power lines, additional safety measures—such as proper training, monitoring, and use of spotters—must be in place to mitigate the risk of electrocution or electrical hazards.

This requirement emphasizes the importance of maintaining a safe distance from overhead power lines while operating cranes, as electrical shock can occur if equipment or personnel come too close to energized lines. The additional precautionary measures mandated by OSHA aim to protect workers and ensure safe operational practices near these hazards.

Understanding the need for maintaining this distance and the accompanying safety protocols is critical for both signal persons and crane operators to ensure workplace safety in environments involving overhead power lines.
