What is the minimum length of overlap between two sections of a 30-foot extension ladder?

The minimum length of overlap between two sections of a 30-foot extension ladder is 3 feet. This requirement is in place to ensure the structural integrity and safety of the ladder when it is extended and in use.

When using an extension ladder, the overlapping sections provide stability by distributing the weight more evenly and reducing the risk of the ladder collapsing under load. The three-foot overlap allows for a safe and secure connection between the two sections, preventing potential movement that could lead to accidents.

Following industry safety standards and manufacturer guidelines is critical, especially regarding the use of ladders. Ensuring the appropriate overlap contributes to a safer working environment, minimizing the risk of falls or injuries.
