What is the significance of using a "tag line" during a rescue?

The significance of using a "tag line" during a rescue operation primarily revolves around its function to control the position of the victim or equipment and minimize swing. In high-angle or technical rescue scenarios, maintaining control is crucial. The tag line acts as a guiding line, helping to stabilize and direct the movement of a rescued individual or equipment as they are being lowered or raised. This control is essential to ensure the safety of both the rescuer and the victim and to prevent any unintended swinging that could lead to injuries or complicate the rescue efforts. By effectively managing the movement, a tag line enhances precision in the operation, which is vital in high-stress and potentially hazardous rescue situations.
