Gasoline doesn’t burn. Gas+air mixture burns and the concentration of gas has to be surprisingly low for the reaction to work - 1 part gas for 14.7 parts air.

Gasoline doesn’t burn. Gas+air mixture burns and the concentration of gas has to be surprisingly low for the reaction to work - 1 part gas for 14.7 parts air. Batteries provide their own air and will burn submerged underwater, if they want to. The firefighting protocol is “Contain fire and wait, sometimes for days”. That’s why the containment cell is designed to be nigh impervious and fire is unlikely. But once a fire starts, good luck.
