What is the recommended angle to set a ladder for safe use?

The recommended angle to set a ladder for safe use is approximately 75 degrees. When a ladder is positioned at this angle, it ensures stability and balance while minimizing the risk of the ladder tipping over. To achieve this angle, a common rule of thumb is to place the base of the ladder one foot away from the wall for every four feet of ladder height. This approach not only enhances safety but also encourages proper use of the ladder, supports workers in maintaining three points of contact, and decreases the likelihood of accidents related to ladder use.

While the other angles, such as 30 degrees or 45 degrees, may seem like alternatives, they do not provide the same level of stability or safety as the 75-degree angle. Setting the ladder too steep (like 60 degrees) or too shallow can lead to it being more prone to sliding or collapsing under weight. Therefore, adhering to the established guideline of a 75-degree angle is crucial for effective and safe ladder use in the construction industry.
