What is anchor redundancy and why is it critical in rescue?

• A. Using a single anchor to maximize force.
• B. Using multiple anchors that are not independent.
• C. Using multiple independent anchors so that the failure of one anchor does not compromise the system.
• D. Anchors placed only at ground level.

Answer: (C)

Anchor redundancy means setting up more than one anchor that can hold the load independently. In rescue work, this matters because any single component can fail—rock can crumble, gear can slip, or rope can suffer a hidden weakness. If you rely on a single anchor, a failure there could undo the whole system and endanger both the rescuer and the patient. Using multiple independent anchors distributes the load and keeps the system secure even if one anchor or its gear gives way.

Independent anchors are placed so their failures aren’t connected; they can be in different rock features or use different anchor types, all oriented to maintain a reliable load path. This independence prevents a single point of failure from collapsing the entire rigging. Anchors placed only at ground level or anchors that are not independent do not provide this safety margin, leaving the system vulnerable to a catastrophic failure.
