Firefighter here. Sometimes a better and less harmful option is to let things burn and protect the area. I went to a semi wreck that was hauling diesel and on fire on its side in the grassy median about 100' away from a storm drain. Trying to put that out with just water would have become an environmental nightmare if all that fuel would have gotten washed into the storm system.

"But electric bad" is what this kind of news will make rednecks think, and they will over sentionalize the conflagration of an ev battery
My primary is a prius and I've done auto work and tech repairs for like 25 years now.
I'm not buying an all electric EV, yet. They're still wasteful and heavy and the battery tech isn't quite good enough. EV's pretty much have a life of 15 years on them (after going through tires faster) and then off to the junkyard once the battery goes out. I have high hopes for the solid state batts from Samsung hitting some production EV's in 2027, though. Lighter, faster to charge, and longer lifespans. Until that, I'm sticking to hybrids, where the battery is less than 100 pounds, cost a few grand instead of $15,000 and you can swap one out at home in an afternoon with no special/expensive equipment.
See, that's why I'm so glad they cleared a whole forest in a water protection area to build their german gigafactory.
Water and trees are totally overrated.

Our town had to use an excavator and dozer to bury a Tesla car because it wouldn't stop burning.

Is water the best choice for a chemical fire?
Depends on the chemical, but it is an appropriate way to fight a liion battery fire though.
You're fighting thermal runaway. Water is very effective at cooling and helps control the fire and keep the heat down. US DOT recommends water spray.

How much is this in Capri Suns?
950,000 Capri Suns
(200ml per Capri sun, 5 Capri sun per litre, 190,000 litres water)
But it would take a long time to open each packet and spray it on the fire.
But it would take a long time to open each packet and spray it on the fire.
- Lay the Capri Suns in the ground next to the fire
- Get another semi truck
- Drive over the packets to squish out the liquid onto the fire
- If the additional semi truck catches fire as well, repeat from step 1
Fuck. Get this dude into Congress right now.

I went through "Bedrijfshulpverlening" (Dutch, if you want to run it through translate just in case I mess up the correct translation). I guess it's business first responder or something.
When we were attending the fire training part and we were teached about fires, someone asked "what if there is a car fire". They said: "starting petrol car fires can be extinguished with a portable extinguisher if you are lucky. But electric car fires, leave them alone. They seal the cars in special water-filled containers and leave them alone for two weeks. There are reports that even after the two weeks, when the car was retrieved from the water, the fire started again on it's own. Firefighters really hate electric vehicles".

How much water does it normally take to put out a semi fire? Say a tire fire, engine fire, or the entire contents of a semi in flames? I couldn’t find the answer googling, but I did find that combustion engine semis burn at the rate of 7000 per year.
