Just a note, in many jurisdictions the proper contact for a cave rescue is 911. That's easier to remember.
Specifically, in most locations, cave rescue teams have no legal authority on their own. 911 can activate the local ICS and legal authorities who will in turn contact the cave rescue team(s) as needed.
Now, the reality is, we've all heard of bungled rescues where non-caver EMS types have tried to perform the rescue. That's an issue best addressed long before a call-out.
For example here in upstate NY, we work closely with the local Sheriff's departments and other agencies. They know in the event of a cave rescue, they're going to call us. And we know they'll take care of everything top side, including those details such as traffic control, addressing possible trespassing issues, providing food if needed, etc.
We pretty much annually run a 2-day OCR course and typically 1/3-1/2 or so of the students are agency folks. Many may never enter a cave again, but they'll at least have a clue of what's we're doing underground during an actual call-out.
Oh, one more thing to add, if you want to set up a local OCR in your area, contact your
Regional NCRC Coordinator and they'll help set one up.
Many are willing to teach for food.
