What is the minimum overlap required between sections of an extension ladder up to 36 feet high?

The minimum overlap required between sections of an extension ladder up to 36 feet high is 3 feet. This requirement ensures the stability and safety of the ladder when extended. Adequate overlap allows the upper section to be securely supported by the lower section, reducing the risk of the ladder becoming unstable or collapsing while in use.

In the context of using extension ladders, following specified overlaps is critical for maintaining safety standards, especially in high work environments. A minimum overlap of 3 feet helps distribute the load effectively and keeps the sections tightly connected to handle the stress experienced during operation. It's essential for users to know these standards to ensure not only their safety but also the safety of those around them while working at height.
