I’m seeing references to, I guess I would call them fire types, that seem to refer to lay of the land, maybe access, structures, fuel type - that sort of thing, that I don’t recognize. I’ve seen references to “Alpha friendly,” Type 2, Type 3, etc. Every search I do comes up with fire extinguishers. Don’t need that. And don’t need the size classifications. Or engine types, aircraft . . .
Help?
