What does the term "pre-tension the system" signify in technical rope rescue?

The term "pre-tension the system" in technical rope rescue refers to ensuring that all system elements and components are secure. This preparation step is critical to establish the operational integrity of the rescue system before any actual lifting or lowering operations begin. By pre-tensioning, rescuers can effectively manage potential slack in the system, reducing the risk of dynamic forces that could endanger both the rescuers and the victim.

Before lifting or lowering a load, ensuring that each component—such as anchors, pulleys, and connection points—is properly tensioned allows for immediate feedback on the system’s stability. This practice helps in mitigating accidents that can occur due to unexpected movements or failures in the rigging setup.

The other options, while relevant to certain aspects of rescue operations, do not accurately describe "pre-tension the system." For instance, having team members ready or preparing to initiate a lift implies action but does not encompass the essential step of securing the system, while putting a rescue operation on hold indicates a pause rather than readiness or preparation.
