The minimum overlap required for extension ladders taller than 48 feet is 3 ft.

People also wonder what the minimum overlap of extension ladder sections is.

Depending on overall length, each section of an extension ladder should overlap the adjacent section by a minimum of a few feet. Overlap shall be at least 3 feet for ex-tension ladders up to 36 feet long, and at least 4 feet for ladders between 36 and 48 feet long.

Similarly, how is the maximum work height determined? The highest standing level must be shown on the side rail’s specifications label. As a result, while planning your project, add the user’s height and reach to the highest standing level to determine the maximum work height.

Furthermore, what is the OSHA ladder standard?

Unless anchored to avoid accidental movement, ladders should only be used on stable and level surfaces. Ladders must be fastened or equipped with slip-resistant feet when used on slick surfaces to avoid inadvertent displacement.

Is it true that the top of a single or extension ladder must expand while approaching a roof?
