What should be the minimum distance maintained from overhead power lines?

Maintaining a safe distance from overhead power lines is critical for the safety of aerial operators and those working around such equipment. The choice stating that a minimum distance of at least 10 feet should be maintained, depending on the voltage level, is correct. This answer reflects the guidelines established by safety organizations and regulations which emphasize that the required distance can vary based on the voltage of the power lines present.

Higher voltage lines require larger safety distances due to the increased risk of electrical arcs and the potential for severe injury or fatality if contact occurs. Thus, assessing the voltage level of nearby power lines is essential to determine the exact distance needed to ensure safety. This practice promotes a comprehensive understanding of the risks involved and the necessary precautions to mitigate them effectively.

The other answers do not capture this critical aspect of safety regulations, either by suggesting distances that may be inadequate for higher voltages or not recognizing the variation necessary based on specific circumstances.
