Sand. Lots of sand. Friends who work in electronics repair have buckets of sand at their station to dump on top of any batteries that are looking like they're going to go thermal run away.

There's several stories of local fire fighters getting Cobalt poisoning in responding to Lithium battery fires. If you see an EV on fire, please stay away from those fumes. They are much more toxic and harmful to human life than any ICE vehicle fire.

Hydrogen is for the most part okay. The cannisters are are well engineered, and we've been moving hydrogen around for dozens of years at this point, so we're pretty good at it. At least with hydrogen, it goes boom, then it is over; as opposed to the lingering contamination caused by other fuel types.

With everything, the more of something we have in existence, the more likely we are to see failures.

A failure rate of 1% on 100 vehicles is 1. That impacts 1 person. If it is 200 vehicles, it is 2. This is obvious and linear.

The cost of dealing with that failure, however is not linear, as there's this lovely thing called cause and effect. Medical responses and emergency preparedness is also not something that works on a linear curve, either.

I really wish I could go back to school and be an actuary. It really is fascinating stuff when you look at how everything interacts with everything else.
