In rope rescue scenarios, the maximum preferred angle for rigging systems is crucial for effective load distribution and minimizing the risk of equipment failure. An angle of 90 degrees is considered ideal because it allows for optimal force distribution across the system, maintaining balance and stability in the configuration. Angles greater than this can introduce additional forces that can compromise the safety and effectiveness of the rescue operation.

When the angle approaches 90 degrees, it considerably reduces the overall load placed on the anchor points and the rigging gear. Angles that exceed 90 degrees can lead to increased tension on the rope, which may result in a decrease in the system's mechanical advantage and increase the potential for tangles and fair leads within the rope.

In contrast, angles such as 100 degrees, 110 degrees, or 120 degrees can significantly increase the stress on both the anchor points and the ropes themselves, leading to potential safety hazards. Therefore, maintaining the angle at or below 90 degrees is not only preferred but essential for ensuring the safety and effectiveness of rescue personnel and equipment during a rope rescue operation.
