What type of items must a person working around energized power lines avoid wearing?

Individuals working around energized power lines must avoid wearing conductive items because these materials can significantly increase the risk of electrical shock or electrocution. Conductive items, such as jewelry, metal tools, or clothing made from conductive fabrics, can create a direct path for electricity, potentially leading to severe accidents. In environments with high voltage, it is critical to maintain a safe distance from any source of electrical current, and conductive materials can compromise that safety.

Rubber gloves are protective gear specifically designed to insulate against electrical current, so they do not pose the same risk. Padded jackets and hard hats are generally not conductive and are used for protection against physical impacts or weather conditions, making them appropriate choices in such work environments. Thus, the correct choice highlights the importance of safety measures in preventing electric shock when working near energized power lines.
