Why is it important to maintain a minimum distance from power lines?

Maintaining a minimum distance from power lines is crucial primarily to prevent electrical hazards and ensure operator safety. Power lines can carry high voltage electricity, which poses a significant risk of electrocution or electric shock if machinery or individuals come into close proximity.

By keeping a safe distance, operators can avoid accidental contact with the lines, reducing the risk of severe injury or fatality. Additionally, this distance helps ensure the proper functioning of equipment without interference from electrical hazards, promoting a secure working environment for all personnel involved.

The other options, while they touch on aspects of safety and operational efficiency, do not emphasize the critical nature of electrical safety in the context of power lines. Proper distance is fundamentally about protecting operators and equipment from the dangers associated with high-voltage electricity.
