What does the term “evidence preservation” mean in a SAR context?

The term "evidence preservation" in a Search and Rescue (SAR) context refers specifically to maintaining the integrity of evidence found during the search. This is critical because any physical evidence collected can be vital for understanding the circumstances surrounding an incident, such as a missing person or an accident. Ensuring that this evidence is not contaminated or compromised allows investigators to draw accurate conclusions and potentially provides crucial information for legal proceedings or future safety measures.

In SAR operations, preserving evidence includes careful handling and documentation of any findings. This might involve techniques like taking photographs, ensuring that items are not moved or altered from their original state, and possibly tagging and bagging items in a manner that preserves their condition for further examination. Proper preservation can lead to a clearer understanding of what occurred, which is essential for the resolution of the incident and for the families involved.
