What is the correct ratio for leaning extension ladders against a wall?

The correct ratio for leaning extension ladders against a wall is 4:1. This means for every four feet of height that the ladder reaches, the base of the ladder should be one foot away from the wall. This ratio is crucial for ensuring stability and safety while using the ladder.

When setting up a ladder, maintaining this ratio helps to distribute the ladder's weight effectively and prevents it from tipping over. If the ladder is placed too close to the wall, the risk of toppling increases significantly, which can lead to falls and serious injuries. Conversely, if it's placed too far away, it may become unstable and difficult to use safely.

Understanding this ratio is vital for anyone working with ladders as part of their agricultural or mechanical tasks, as it promotes safe practices and enhances the overall safety of the working environment.
