How far must climbing ladders extend beyond the top support?

Climbing ladders must extend at least 3 feet beyond the top support to provide a safe and secure handhold for climbers when ascending or descending. This extension allows workers to maintain three points of contact while transitioning onto a platform or roof edge, significantly enhancing safety by reducing the risk of slipping or falling.

A ladder that does not extend sufficiently beyond the support point can create a hazardous situation where the climber may have to reach uncomfortably, compromising stability. By adhering to the guideline of a 3-foot extension, workers ensure there is enough space to grasp the surface above comfortably, preventing accidents and promoting safe climbing practices.
