Choosing the Right Ladder
Only choose ladders with the UL (Underwriter’s Laboratory) seal. Ladders are made of one of three materials: wood, aluminum, or fiberglass. Aluminum ladders are dangerous around electricity because they conduct electricity, although it is the least likely to break down over years of use. Wooden ladders are not cunductive to electricity, but they can rot when exposed to moist conditions over time. Fiberglass ladders offer the best choice for both for long life and safety from electrical conductivity. The drawback is that fiberglass ladders are also the most expensive.
