Which ladder material should be selected when working near a source of electricity?

When working near a source of electricity, selecting fiberglass as the ladder material is crucial due to its non-conductive properties. Fiberglass does not conduct electricity, making it the safest option for situations where electrical hazards are present. This characteristic significantly reduces the risk of electrical shock, which can be a serious concern when operating with conductive materials like aluminum or steel.

Wood, while also non-conductive, can be less durable and may not provide the same level of structural stability as fiberglass ladders. Therefore, when considering both safety and performance in electrical environments, fiberglass is the preferred choice due to its strength, durability, and safety features.
