What is important when determining the correct angle for a ladder?

Determining the correct angle for a ladder is crucial for safety and stability. A ladder set at the proper angle reduces the risk of slipping and increases the worker's balance while they are climbing or standing on it. The recommended angle for a ladder is typically around 75 degrees, which can be achieved by using the 4-to-1 rule: for every four feet of height, the base of the ladder should be one foot away from the wall or vertical surface it's leaning against.

Stability is an essential factor because a ladder that is too steep may cause it to tip over backward, whereas one that is too shallow can slide out from underneath the user. Therefore, checking that the ladder is stable and positioned at the right angle contributes significantly to preventing accidents while using the ladder. Proper use ensures that individuals can safely perform tasks at height without the added risk of falling or the ladder collapsing.
