What does an anchor system consist of?

An anchor system consists of multiple anchor points arranged for structural support, providing a stable and reliable foundation for the rescue operation or climbing activity. This arrangement is crucial because the combined strength and redundancy of several anchor points enhance the safety and effectiveness of the system.

Using multiple anchor points allows load distribution, ensuring that if one anchor point were to fail, others can still support the load, significantly reducing the risk of accidents. In rope rescue scenarios, having a robust anchor system is vital for the safety of rescuers and victims alike. The strength in the diversity of anchor points can accommodate dynamic forces that may occur during a rescue, such as sudden movements or shifts in position.

The other choices do not capture the essential elements of an anchor system adequately. A single knot connecting the rope to one point lacks the safety and redundancy necessary for rescue operations. A bight in multiple lines of rope, while useful in certain contexts, does not represent a fixed and stable anchor system. A hitch designed for quick release is useful for specific applications but does not address the overall structure needed for an anchor system in a rescue scenario.
