Fiberglass ladders are preferred around exposed energized conductors because they are nonconductive.

Fiberglass ladders are preferred around exposed energized conductors because they are nonconductive.

• A. True
• B. False
• C. Not always true; depends on voltage
• D. Only if insulated

Answer: (A)

Fiberglass ladders are nonconductive, so they don’t provide a path for electrical current under normal conditions. When you’re working near exposed energized conductors, using a nonconductive ladder helps reduce the risk of shock if you or the ladder comes into contact with live parts. This insulation works because the fiberglass composite resists conductivity, unlike metal ladders that can become energized and carry current. The safety benefit holds best when the ladder is dry, clean, undamaged, and within its dielectric voltage rating; moisture, dirt, or damage can degrade insulation, and exceeding the ladder’s rating can compromise protection.
