Underwriters Laboratories (UL) and other rating agencies warn consumers not to bring their ladders within 10 feet of overhead power lines. And they recommend using fiberglass or wood ladders when working anywhere near electric wires or equipment. But any material can allow electricity to pass through it if wet.
* Buy ladders with a seal from the UL or another accredited rating agency.
* Choose a ladder that is long enough for your job. Using a ladder that's too short is the culprit in many accidents.
* Distribute your weight evenly, and don't overextend your reach.
