What should be done if two or more critical criteria are not present during a rescue operation?

In the context of a rescue operation, if two or more critical criteria are not present, it is essential to prioritize safety and reliability. Utilizing a Safety Management and Systems-Based (SMSB) approach is favored because this method emphasizes improved consistency and risk management. By adopting SMSB, rescuers can systematically evaluate the situation and make informed decisions that enhance safety for both the victims and the rescuers.

The approach encourages teams to re-assess their methods and introduce alternative techniques or systems that can better accommodate the current conditions. This proactive strategy helps manage the risks involved in rescues where critical criteria are not met, ensuring that the operation aligns more closely with established safety protocols.

The other choices present less advantageous options when critical criteria are lacking. For example, aborting the rescue may not always be feasible if lives are at stake, and continuing with the planned technique despite significant safety concerns heightens risks. Likewise, the suggestion to utilize DC-TTRS for all loads may not specifically address the absence of critical criteria, as it doesn't necessarily improve safety or reliability if the foundational conditions aren’t met.
