Which method is NOT used to highlight the position of powerlines in work zones?

Highlighting the position of powerlines in work zones is critical for safety and awareness. Using methods such as tiger tails, marker balls, and signage effectively indicates the presence and location of powerlines to help prevent accidents.

Tiger tails are flexible, brightly colored materials that are suspended from powerlines to make them more visible, especially for those who might be operating equipment in the area. Marker balls, typically large, visible spheres, can also be attached to lines, serving a similar purpose of increasing visibility. Signage is crucial in notifying workers and the public of the presence of powerlines and any associated risks, thus enhancing safety.

While cones are widely used for various purposes in work zones, they do not serve the specialized function of highlighting overhead powerlines. Their primary purpose is to redirect traffic or establish boundaries within a workspace but they do not provide specific information about electrical hazards. Therefore, among the methods listed, cones are not utilized for marking powerline locations.
