What is the recommended distance a non-self-supporting ladder should be placed from a vertical structure?

The recommended distance for placing a non-self-supporting ladder from a vertical structure is 6 feet. This distance is based on the angle of the ladder against the wall, which is typically set at about 75 degrees from the ground for optimal stability and safety.

When the base of the ladder is positioned one-fourth of the ladder's working length away from the wall or structure, it helps ensure that the ladder maintains a secure and balanced position. This setup minimizes the risk of the ladder slipping or tipping, which is crucial for preventing accidents while climbing.

Positioning the ladder too close can make it unstable, while placing it too far increases the chance of it falling backward. Thus, maintaining this 6-foot distance aligns with safety guidelines that promote effective use and minimize hazards when working at height.
