What does the 4 to 1 rule help to ensure?

The 4 to 1 rule is a safety guideline used when setting up ladders to ensure stability and safety while climbing. This rule specifies that for every four feet of ladder height, the base of the ladder should be one foot away from the wall or structure the ladder is leaning against. This proper angle helps maintain the ladder’s balance, preventing it from tipping over or slipping while a person is on it. Thus, by following the 4 to 1 rule, individuals can significantly reduce the risk of falling when climbing the ladder, enhancing overall safety.

While other factors like proper balance, correct height, and weight support are important when using a ladder, the primary focus of the 4 to 1 rule is to ensure a safe climbing angle and stability during use.
