What is the primary use of extension ladders?

The primary use of extension ladders is to provide access to elevated areas, such as service connections to buildings. These ladders are designed to extend and allow linemen and other workers to reach higher locations safely. Their adjustable length makes them versatile for accessing rooftops, power poles, or service lines that are installed at various heights.

Extension ladders are specifically built for stability and support when being used to reach higher points while ensuring that the users can maintain balance and safety. This function is essential in the lineman profession, where work often involves connecting, repairing, or servicing overhead electrical infrastructure. The ability to extend the ladder to the necessary height while ensuring it remains secure is crucial in preventing accidents and injuries while performing electrical work.

Other options do not accurately represent the primary use of extension ladders. For example, using extension ladders as support structures during construction does not leverage their intended purpose, and they are not typically used for storing equipment at height or actively connecting power lines.
