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)

The main idea here is safety through redundancy: making sure the system stays secured even if part of it fails. In rescue work, anchors can fail due to rock issues, wear, or equipment problems, and a single point of failure can lead to a catastrophic collapse of the whole setup. By using redundant anchors and protecting against that single-point failure, the load has alternatives to transfer to, so the system remains intact and the team can stay safe or complete the operation.

Redundancy means you set up multiple independent anchors and keep backup lines or equalized anchors so that if one point slips or breaks, the others still hold. It’s not about loading more onto one anchor; it’s about creating a fail-safe path. The other options misunderstand the goal: increasing load on anchors, reducing the number of anchors, or avoiding redundancy would all undermine safety and the ability to withstand unexpected failures.
