What is the purpose of a tensioned diagonal in rescue operations?

The purpose of a tensioned diagonal in rescue operations is to move people and equipment across at a 45° angle. This technique is essential in various rescue scenarios where direct access is not possible due to obstacles or the nature of the terrain. By utilizing a tensioned diagonal, rescuers can effectively navigate across areas that may be challenging, such as swiftwater or steep terrains.

When moving victims or equipment at a 45° angle, it allows for a more stable and controlled transfer while maintaining tension in the line, which helps to counteract the forces acting on the load. This method is particularly useful in swiftwater scenarios where water movement might otherwise carry the load away or create instability if approached from a direct horizontal or vertical angle. By employing a diagonal approach, rescuers can ensure better safety and efficiency in their operations.
