Metal ladders and overhead power lines are a bad combination. Every year, painters and tree trimmers learn this the hard way, resulting in injuries and electrocutions. Using power tools while working off a metal ladder also can be hazardous, especially during wet weather.
Electricians use wood or fiberglass stepladders and fiberglass extension ladders when they work. Fiberglass is nonconductive; wood also is an excellent insulator as long as it’s dry. Most extension ladders aimed at the homeowner market are inexpensive metal ladders. If you’re doing any serious overhead electrical work, however, a wood or fiberglass ladder is the better choice.
