Old nitro racer, here. Front engine T/F cars.
We had an experience with a nitro fire, in our Dodge D500 tow wagon. Didn't know it was burning until our eyes started watering!
Instead of putting the nitro jugs where they should have been, one was in the back of the wagon.
As luck would have it, the tool box slid into the lic plate light wire, and cut it open. The corner of the box poked a hole in the plastic nitro jug.
You can imagine the rest.
Fire extinguishers? Nope! Dirt from the roadside was the best we could do.....
Alky? Nope. Throw in the can and the label, and race it.
We did ok, until we got really "smart", and added some hydrazine and propylene oxide, to the mix...The ol' 392 didn't react well, to that swill.
Lots of old tymie stories...
I've gone to non corn regular in the farm stuff, and have switched to 56V electric leaf blower and weed eater. Only oil mix left, is the chain saw.
The white
you see in the vid is what I find on the top of some of the injs I clean. I call it "corn starch".
