What angle is considered appropriate for directional anchors in rope rescue?

For directional anchors in rope rescue, an angle of 120 degrees or greater is generally considered appropriate. This is because larger angles can help distribute the load more evenly across the anchor points, reducing the risk of failure under tension. When the angle is 120 degrees or greater, it ensures that the force is effectively shared between the anchors, maximizing safety and stability during the rescue operation.

In contrast, smaller angles can concentrate forces on the anchor points, increasing the risk of failure or slippage. Keeping the angle at this range allows the rescuers to maintain better control over the system while minimizing the chance of failure during dynamic situations. Therefore, maintaining an angle of 120 degrees or more provides optimal performance and safety for directional anchors in a rope rescue scenario.
