What is true about the belay line?

The belay line is a crucial safety component in rope rescue operations, and it must always be the first line attached. This ensures that there is a secure backup in place before any primary rescue actions begin. By attaching the belay line first, rescuers provide a necessary layer of safety, allowing them to perform their tasks with the assurance that in the event of a primary line failure, the belay line will catch or support the rescuer.

This practice aligns with standard safety protocols, which prioritize the establishment of a belay system before placing any load on other lines to minimize risk during rescue operations. The design and function of the belay line are intended to provide security and control, making it a foundational element in effective rope rescue procedures.
