It Took 36,000 Gallons Of Water To Extinguish A Burning Tesla
A Tesla fire on I-65 in Alabama tested the capabilities of local emergency responders.
A new crash recently in Alabama, but a reminder to something that we all know. Burning Teslas are far more difficult to extinguish than any other car.
You're viewing part of a thread.
So you've chosen a lab manual from some small classroom in some university out there.
Sure, lets get into a citation war. My choice of citation is the US Fire Administration. See here: https://www.usfa.fema.gov/blog/ig-062322.html
Listed is many EV manufacturer's official recommendations for how to fight an EV fire. I'm choosing a large, well respected EV manufacturer. Lets choose Rivian for sake of this argument.

Page 23 of their manual states:
Oh look at that? They say to use thousands of gallons of water (2000 to 3000 gallons for the initial fire), and then work to keep the Li-ion cells below 100C for at least the next 24-hours (which is obviously easiest in what I've discussed elsewhere in this thread: a full submerged container). I've seen other fire-department manuals recommending 7-days (a full week) of submerged cells just to be sure.
In practice, fire-departments do not have the equipment for that long-term sustained cooling. So they end up baby-sitting the car for like 8+ hours and keep spraying it with a hose every few minutes, wasting tens-of-thousands of gallons of water. Its not the best solution and its a high cost both in water and fire-department's time, but it does work when a container (or other device) is unavailable.
Step 1 only extinguish if you have specific need to.
They recommend letting in burn unless you must extinguish it actually.
Sure, you win. That was the first result that came up for me on google. If I have a class B fire extinguisher around then I'll use that before using water.
The problem is that a fire extinguisher only works on the initial flames. If the battery pack remains overheated (as is the case in a large vehicle fire), it will spontaneously combust a few minutes later. This problem is well documented in all the fire-department manuals / discussion on EVs.
So you're literally spreading misinformation on how to properly fight an EV Fire. I mean, not on purpose or whatever, what you're saying is a common misconception. But IMO, its in our best interest to spread the proper firefighting tactics across our society so that everyone's on the same page on the dangers here.
Well, I don't have an EV and I'm not a firefighter, so EV battery fires aren't on my radar. If I had an EV and it caught fire I'm not going to try and put it out. The biggest batteries in my life these days are less than 2kWh, so I'm going to use the class B fire extinguishers I bought after I've already called the fire department.
Maybe don't comment on the subject then?
