A genny has a 12V car/lorry battery to start it. My work one is basically a lorry diesel motor on a floor bolted chassis. It is the other side of an external wall (double skin of brick). Ironically enough the genny is inside the same room as the hot water boiler which is gas powered. The original heating was a coal fired boiler which was converted to a weird oil squirting "hair dryer". That's all gone now.
The fire risks that I worry about do not really include the genny. The fridge in the kitchen is potentially far worse. I have, of course, put in a fire detection and suppression system inside the computer room.
At home I actually have a more involved fire risk assessment than at work. My wife does dog boarding at home and one day I will stop her leaving a cloth to dry on the cooker ... sigh. Anyway, making sure that humans and dogs get warned and get out safely is quite involved.
As we all know there are three ingredients required for fire: a source of ignition, a combustible material and finally: oxygen. Remove one and fire does not happen. Unfortunately some reactions will generate copious amounts of heat and oxygen, ie all three requirements for combustion and become self sustaining. Lithium batteries for example can do this. It's a bit of a nightmare but techniques are being developed to deal with "self igniting metals" and the like.
Diesel fuel is particularly hard to ignite which makes it not too much of a worry in a fire. By the time the fuel tank is on fire the fire department has given up on your building and are just trying to stop the spread to other buildings.

I drive an EV.
