Preparing for evacuation involves several steps.

1. Prepare the casualty to be evacuated (securing loose bandages, equipment, blankets, etc.) and place them on a litter appropriate for the type of evacuation.
2. Prepare the site by directing the supporting personnel to establish security and a casualty movement process (often with litter-bearer teams), and by staging the casualties in the correct priority for evacuation.
3. Prepare the incoming evacuation assets by communicating with them about the casualty status and anticipated requirements during the evacuation.
