Can figure 8 descenders be used as belay devices when a rope is placed in the large opening?

Figure 8 descenders are primarily designed to be used for controlled descent and should not be utilized as belay devices when the rope is placed in the large opening. This stems from the design and function of the figure 8; when used in this manner, it does not provide the necessary friction or control that is crucial in a belaying scenario.

Belaying requires a device that allows for controlled feeding and catching of the rope during climbing, ensuring the safety of the climber in case of a fall. The large opening of a figure 8 descender does not facilitate this type of operation effectively. Instead, figure 8s are intended to create controlled descent or lower individuals safely from heights, in their correct orientation and application, avoiding misuse that could lead to serious accidents.

Understanding the proper applications and limitations of climbing equipment is essential for ensuring safety in rescue operations.
