Non-conductive ladders are typically made from which materials?

• A. Aluminum and Steel
• B. Wood and Fiberglass
• C. Plastic and Glass
• D. Brass and Copper

Answer: (B)

Non-conductive ladders are designed to minimize electrical shock risk when working around energized parts. Wood and fiberglass provide true insulation, so they don’t easily carry electricity. Wood remains insulating when dry, and fiberglass ladders use a fiberglass composite that resists current while maintaining strength. Metals like aluminum and steel conduct electricity, making them unsafe for electrical work. Plastic and glass aren’t standard ladder materials for HVAC use due to issues with strength, durability, and practicality, and they don’t offer reliable insulating performance in typical conditions. Therefore, wood and fiberglass are the typical non-conductive choices.
