Which of the following is NOT a primary consideration during an emergency rescue?

In an emergency rescue situation, the primary considerations typically emphasize the immediate safety of both the rescuers and the individuals being rescued. The safety of the rescuers is paramount; without ensuring their safety first, the entire operation could be jeopardized, potentially leading to further injuries. Rescue speed is also critical, as prompt action can significantly increase the chances of survival for those in danger. Effective communication among rescuers is essential to coordinate efforts efficiently and to relay important information about the situation.

Preservation of evidence, while important in the context of investigations after the fact, does not take precedence during the actual rescue effort. The primary goal in emergencies is to save lives and ensure safety, as the urgency of the situation means that immediate action must be prioritized over collecting evidence. Thus, the correct answer highlights that preserving evidence is not a primary concern during the rescue phase itself.
