Check-out occurs:

The process of check-out is essential for ensuring that all personnel involved in a Search and Rescue operation are accounted for and have completed their tasks satisfactorily. When check-out occurs upon departing the incident, it serves as a formal closure of the mission for each team member. This step typically involves confirming that all team members are present, that equipment has been accounted for, and that any relevant data or observations have been recorded and communicated to the appropriate authorities.

This procedure helps to maintain the integrity and accountability of the SAR team, ensuring that everyone is safe and that any lessons learned during the mission can be documented for future operations. While the other stages mentioned are important parts of the SAR mission process, check-out is specifically focused on concluding the mission effectively, and thus it is distinct from briefings and debriefings which serve different purposes in the operation.
