What is a tag line used for in confined space rescue?

A tag line is an essential tool in confined space rescue, primarily used to assist in locating entrants or rescuers. When individuals enter confined spaces, visibility and orientation can often be limited. The tag line, which is a lightweight rope attached to the harness of the person inside, allows rescue teams to maintain communication and track the location of the individual. This is crucial for ensuring the safety of both the rescuer and the person in the confined space as it provides a means to locate them quickly during an emergency.

While other options may have some relevance in rescue scenarios, they do not capture the primary function of a tag line as effectively. For instance, an anchor point is typically established with more robust equipment, and securing the stretcher during a lift is more about ensuring load stability than tracking individuals’ locations. Marking hazardous areas, although important in the context of safety, does not directly relate to the specific purpose of a tag line in the rescue process. Therefore, option B accurately describes the function of a tag line during confined space rescues.
