What type of ladder is typically used by linemen for utility work?

Extension ladders or specialized fiberglass ladders are the most appropriate choice for linemen engaged in utility work due to several critical safety and functionality features.

Fiberglass ladders are non-conductive, making them ideal for work around electrical lines where the risk of electric shock must be minimized. These ladders provide the necessary height for utility tasks while ensuring that linemen can maintain a safe distance from conductive materials. Additionally, extension ladders can be adjusted to various heights, making them versatile for different work situations that linemen may encounter.

In contrast, other types of ladders, such as wooden and aluminum ladders, are not specifically suited for utility work. Wooden ladders can be heavy and less durable when exposed to harsh weather conditions, while aluminum ladders, although lightweight and portable, are conductive and thus not safe for use around electrical installations. Step ladders, while useful for a range of tasks, lack the height and stability that linemen require for reaching utility poles or other elevated work sites. Therefore, extension and specialized fiberglass ladders stand out as the best choice for linemen.
