What should be the angle of a ladder when placed for use?

The proper angle for a ladder when it is set up for use is indeed around 75 degrees, as this configuration ensures the ladder's stability. When a ladder is positioned at this angle, it provides a strong balance between securing the base and allowing for adequate reach without compromising safety. A ladder that is too steep can be difficult to climb and increases the risk of slipping or losing balance, while too shallow an angle can cause the ladder to tip over. By adhering to the recommended 75-degree angle, users can maximize safety while working at heights.

This angle allows the weight of a person climbing the ladder to be evenly distributed, which helps in maintaining a solid grip on the rungs. Additionally, it also enables users to comfortably shift their body weight as they ascend or descend. Understanding ladder placement and angles is critical in construction and maintenance environments to minimize accidents and ensure safe practices.
