During rappelling, what technique is used to control the descent?

The technique employed to control the descent during rappelling involves the use of a rappel seat along with the brake hand on the rope. This method is essential for maintaining safety and ensuring a controlled descent. The rappel seat, which is a specific type of harness that securely attaches the individual to the rappel line, provides support and stability during the descent. The brake hand plays a crucial role in regulating the speed of descent; by applying pressure to the rope, the individual can slow down or stop their descent altogether.

This combination of equipment and technique allows for precise control over the rappelling process, making it effective for safely navigating various heights and obstacles. Proper training in these techniques is vital, as it equips individuals with the necessary skills to manage descent under various conditions, reducing the risk of accidents or injuries during operations.
