Why should anchors be redundant and protected against single-point failure?

• A. To prevent catastrophic failure if one anchor fails and to maintain safety
• B. To increase load on anchors
• C. To reduce the number of anchors used
• D. To avoid redundancy in the system

Answer: (A)

Redundancy in anchors is about making the system resilient to failure. In rescue and rope systems, a single failed anchor can lead to a dangerous loss of support. By using multiple independent anchors and spreading the load across them, the system still holds if one path fails. This creates a safety margin against wear, gear defects, rock movement, or sudden dynamic forces from a fall. The goal is safety and continuity of support, not to increase the load on any one anchor or to avoid using backup options. Redundancy prevents a single point of failure from turning a controllable situation into a catastrophe.
