What is the minimum test load that general use DCDs must withstand?

The correct answer is based on the standards and regulations that govern the performance of dynamic climbing devices (DCDs) in rescue operations. The minimum test load that general use DCDs must withstand is established to ensure that these devices can reliably handle the forces encountered during actual rescue situations.

A minimum test load of 22 kN ensures that the DCDs are robust enough to withstand the significant forces that can occur when they are employed in rescue scenarios. This load tests the structural integrity and functionality of the devices, confirming they will perform effectively under load during critical situations. This safety margin is essential for the protection of both rescuers and those being rescued.

The other figures do not meet the established safety standards for DCD performance. Therefore, the specified minimum of 22 kN is pivotal in maintaining the safety and reliability of rescue operations.
