If you haven't given up for good here's some more advice
- don't finish a turn standing next to fire. It can flare up and KO your firefighter
- put out smoke where you can. It takes less AP than fire, and if fire appears next to it, all adjacent smoke will turn to fire!
- close doors to stop the spread of fire
- move victims to safe spots to be collected by paramedics/rescue specialists, rather than tying up a firefighter for the whole rescue
