What is the primary hazard associated with overhead power lines?

The primary hazard associated with overhead power lines is the risk of electrocution from contact with energized lines. Overhead power lines carry high voltage electricity, and any direct contact with these lines can result in serious injury or death due to electric shock. This danger is especially prevalent for individuals working near or around these lines, such as utility workers, tree trimmers, or construction crews. It is critical to maintain a safe distance from power lines and to always assume that they are energized, as this awareness can significantly reduce the risk of accidents.

While other hazards like falling objects or weather conditions can pose risks, they are secondary when it comes to the immediate threat posed by contact with the high-voltage lines themselves.
