In what situation should a link line be utilized during a mine rescue?

Utilizing a link line during a mine rescue is particularly crucial in low visibility situations. When visibility is impaired, whether due to smoke, dust, or darkness, it becomes challenging for rescuers to navigate safely. A link line serves as a critical lifeline connecting team members, ensuring that they can maintain communication and orientation while working in these hazardous conditions.

In such environments, team members may easily become disoriented and lose sight of each other, which increases the risk of separation and compromises the effectiveness of the rescue operation. By using a link line, rescuers can guide each other along predetermined routes, helping to ensure that everyone remains together and can respond quickly to any emergencies.

High visibility areas, open spaces with clear paths, and familiar territories generally allow for easier navigation where the risk of losing contact is lower, making the need for a link line less critical in those circumstances.
