At what angle should a leaning ladder be used?

1. 60 degrees

2. 75 degrees

3. 90 degrees

4. 45 degrees

The correct answer is: 75 degrees

Using a leaning ladder at an angle of 75 degrees is recommended for a balance between stability and safety. This angle allows the ladder to maintain a secure base while providing a safe working position for the user. At 75 degrees, the ladder is steep enough to prevent it from being too shallow, which could increase the risk of slipping out from under the user during ascent or descent. Additionally, this angle minimizes the strain on the user, as it ensures that they can maintain a comfortable stance without overreaching or leaning too far to one side. Proper ladder safety guidelines suggest this angle to enhance the overall effectiveness of the ladder setup and prevent accidents related to incorrect positioning. While other angles may be used, such as 60 degrees, which might seem appropriate, it is less optimal for ensuring the ladder’s stability and safety. Using a ladder at 90 degrees would essentially place it vertically without any support at the base, leading to a high risk of toppling. A 45-degree angle would likely create a less stable position, increasing the chances of the ladder sliding or being less secure. Thus, the 75-degree angle is the most suitable choice for safe ladder use.
