What is the maximum force that a belay device should generate when arresting a load?

The maximum force that a belay device should generate when arresting a load is crucial for ensuring safety during a rope rescue operation. The correct value is 12 kN, as this is generally accepted as an appropriate limit for dynamic forces in many belay devices designed for rescue operations.

This figure is established to give sufficient strength to handle the dynamic forces that occur during a fall or sudden stop while maintaining adequate safety margins to protect both the rescue technician and the equipment. By adhering to this standard, rescuers can effectively manage the risks associated with falls and sudden impacts.

Other values such as 10 kN, 8 kN, and 6 kN may not provide the necessary safety factor or could be too low for certain rescue scenarios, particularly in cases involving heavier loads or more dynamic movements. The 12 kN threshold delivers both the capability to safely arrest a falling load and the reliability needed for intensive rope rescue tasks.
