Which practice helps prevent single-point failure in ice rope rescue anchors?

• A. Using multiple anchors and cross-checking stability.
• B. Using a single anchor.
• C. Tying to a moving object.
• D. Relying on a dry surface.

Answer: (A)

Redundancy in anchor systems is crucial in ice rope rescue. By placing more than one anchor and confirming that each is solid and capable of taking a share of the load, you avoid depending on any single point. If one anchor fails or ice cracks, the others still hold, keeping the victim and rescuers safe. Cross-checking stability means testing and rechecking each anchor under load, verifying that the load paths are correct and that the anchors are securely configured to share or distribute forces as planned. This solidifies the system against unpredictable ice conditions and partial failures, which is essential in the inherently uncertain environment of ice. Using a single anchor creates a single point of failure; tying to a moving object introduces unpredictable movement and potential shock loading; and relying on a dry surface can be misleading since ice can be wet or cracked and may not provide reliable support. The best practice is multiple anchors with cross-checking to ensure redundancy and dependable load sharing.
