And how do they deal with the tank of explosive fluids inside fire trucks today?

Precautions around keeping a fuel tank from catching fire work the same for batteries. Better, because lithium batteries have an ignition temperature at 2000F and gasoline's is 500F and diesel at 410F.

Explosion proof, fire arresting, multi layered tanks, which are in use since forever (planes and other critical vehicles also use that technology).

Also, you can’t ignite fuel without a spark. A cigarette can’t light a tank of fuel, but an overheated battery can catch fire by itself.

Lastly, you can extinguish fuel fires, but you can’t extinguish metal fires.

This is a shockingly high amount of FUD but little facts.

Lets start at the top shall we?

Diesel doesn't "burn" like gasoline does.

"If you toss a lit match into a puddle of diesel fuel, it'll go out."

You need to atomize it first, or heat it up a lot so it starts to "flash" or it wont "burn".

So, a firetruck with a large diesel tank is fairly safe because it takes a LOT to get it to start burning. At first all the heat is simply absorbed by the diesel slowing warming it up until it reaches its flash point.

Next, your temperatures are beyond MESSED UP.

Ignition temperature for a lithium battery is just 121 C

The Auto-ignition temperature of pure lithium is just 179°C

I have no idea where you get 2,000F (1,093C) from but this is so wrong it is embarrassing. This temperature is almost to the point Iron catches fire:

Batteries are also prone to shorts and spontaneous fires which may explain stories like this : https://www.republicworld.com/world-news/us-news/tesla-model...

There is also the "fun" reaction between Lithium and water, which firefighters often use on fires...
