I don't know if it applies in this scenario, but when the Dept of Homeland Security was created, they started a program called CERT: Community Emergency Response Teams. Each community's law-enforcement agency would train civilians to help first responders. When I taught at a college, I was part of the campus CERT. Our campus police dept trained us in search-and-rescue, triage, and other stuff. (Not rescuing people in a snowstorm, however.) We all received certification in basic first aid, CPR, fire extinguishing, and using a Stryker Chair. We were given a backpack of equipment and told to keep it in our offices and be ready to respond if we were called.
Seems like the same concept could be used here, with the conditions you suggested.
