What is recommended for angles over 120 degrees in an anchor system?

In anchor systems, managing the angle between anchors is crucial for ensuring safety and efficiency during a rescue scenario. When the angle exceeds 120 degrees, it can lead to increased forces being transmitted through the anchors. Specifically, with larger angles, the tension in the rope increases significantly, which could place a dangerous load on the anchors and possibly lead to their failure.

Avoiding angles over 120 degrees is recommended to minimize these risks. By maintaining a tighter angle (ideally below 120 degrees), the forces are more evenly distributed, leading to safer operation and reducing the likelihood of anchor failure. This practice is rooted in the principles of force management and the engineering behind rope rescue systems, where the integrity of the anchor points is paramount.

The other options may seem reasonable but do not effectively address the fundamental issue related to high angle scenarios. Increasing the number of anchor points might provide some redundancy, but it does not control the force dynamics imposed by an obtuse angle. Switching to a static load does not inherently solve the problem of increased angle forces. An additional shock absorber can help to dissipate energy from dynamic loads, yet it does not mitigate the inherent risks associated with large angles. Thus, the best practice remains to avoid using angles over 120 degrees in the
