The first result for my query says "copious amounts of water are recommended as the best means to extinguish a high voltage vehicle fire." What did you find?
I'm guessing those strategies work well for phones but maybe not cars which are absolutely enormous amounts of battery and possibly wrapped around a tree at the time of the fire.
Secure a large, continuous and sustainable water supply — one or more fire hydrants or multiple water tenders. Use a large volume of water such as master stream, 2 1/2-inch or multiple 1 3/4-inch fire lines to suppress and cool the fire and the battery.
Right. A fire extinguisher is a "first aid" response to a fire. The kind of advice that's relevant to fire extinguisher usage is predicated on a small fire; general advice is that any fire larger than a small trash can is too big to fight with an extinguisher.
The fire department plays from a different rule book.
A lithium battery fire is considered a class B fire, so pouring water on it is not standard procedure. They should have known that in the first place, but if they had googled it, they would have found out very quickly anyway.
Yes, my point is that a possible explanation for using 32,000 gallons and calling Tesla is that spraying 3,000 gallons on the battery did not successfully extinguish it.
What you are overlooking is that the correct procedure as documented by Tesla, which is what the firefighters had been doing for four hours, didnotstopthefire.
Sounds like they did already know this and that's why they did it. If they googled it, they might have got the wrong answer like you did. So your criticisms aren't valid.
