Which materials are used for non-conductive ladders?

• A. Aluminum and Steel
• B. Plastic and Glass
• C. Wood and Fiberglass
• D. Carbon Fiber and Ceramic

Answer: (C)

Non-conductive ladders are made from materials that don’t readily carry electricity, which helps prevent electric shock when you’re working near live wires. Metals such as aluminum or steel conduct electricity, so ladders made from those materials are not suitable for electrical tasks. Fiberglass is a common non-conductive choice because it resists electricity and is strong enough for climbing. Wood is also non-conductive in typical conditions, making it another safe option for environments where electrical exposure is a concern. The other options rely on materials that either conduct electricity or are impractical for ladders (glass is brittle and not a reliable ladder material; carbon fiber and ceramic aren’t standard ladder materials). Thus, wood and fiberglass best fit the non-conductive requirement.
