Not combat related - But anybody have game mechanics for fire fighting?

[Skarg]

One could start with the missing rules for how hard it is to put out the fire on someone soaked in burning molotail oil.

I'd love to see a fun set of fire rules that makes fire spread and extinguishing and smoke and so on interesting and reasonable.

It comes up pretty often in play - people wanting to use fire arrows and other pyromaniac antics to burn things down, etc.

Accidental fires can also spring up from dropping & knocking over light sources, missing with fireballs and molotails, flaming weapons, etc.
