Well, there may not be a fire, but you might get drenched with electrolyte.
I’ve never heard of someone getting into an accident and ending up drenched in gasoline, motor oil, coolant, transmission fluid, or even wiper fluid.
Even in gasoline car fires that end up causing injuries, I don’t think the victims get gasoline splashed on them. Generally the fire starts outside the cabin and the victims are trapped or unconscious and can’t escape in time, since gasoline burns quickly.
With the two Volt fires, it took over a week for the battery to catch on fire, so I don’t think the risk is meaningful.
