You’re welcome, Bingley.

Another potential resource for your friend might be a local Community Emergency Response Team. CERT training is free and there’s no obligation to join the team. While it’s been a while for me and I don’t know how the curriculum has changed, we learned light search and rescue, light fire suppression, shutting off utilities, scene safety, first aid, how to handle mass casualty events, basics of the Incident Command System, and more.

If your friend is interested in emergency communications, the ham radio community does a very nice job of teaching this. The Technician license requires passing a straightforward multiple choice test; there is no longer a Morse code requirement to get licensed in the USA. I’m happy to share resources for anyone who’s interested.

CPR and Stop The Bleed training are easy and inexpensive to get. A more thorough grounding in treating traumatic injuries can be found by looking for medical courses aimed at firearms instructors.

I’m not sure what else to suggest — I wouldn’t be surprised at all to learn you suggested all of these.
