California firefighters had to douse a flaming battery in a Tesla Semi with about 50,000 gallons (190,000 liters) of water to extinguish flames after a crash, the National Transportation Safety Board said Thursday.
In addition to the huge amount of water, firefighters used an aircraft to drop fire retardant on the “immediate area” of the electric truck as a precautionary measure, the agency said in a preliminary report.
Firefighters said previously that the battery reached temperatures of 1,000 degrees Fahrenheit (540 Celsius) while it was in flames.
The NTSB sent investigators to the Aug. 19 crash along Interstate 80 near Emigrant Gap, about 70 miles (113 kilometers) northeast of Sacramento. The agency said it would look into fire risks posed by the truck’s large lithium-ion battery.
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.
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.
And morons keep buying Teslas.
It really seems like Elon Musk has been given free reign to kill people.
This is not a Tesla problem. This is electric vehicle problem.
My local fire department once had to put out the same VW Buzz 3 times because it kept re-igniting. Nowdays they have containers filled with water that they completely submerge electric vehicles into that had caught fire.
It’s a Tesla problem in that it is a bumrushing tech that hasn’t matured for what it’s being used for because profit motive.
And no, if the tech isn’t mature to be both useful AND safe in the event of failure operating in the world, it belongs in the lab, not up for sale.
We shouldn’t be mass producing any vehicles that become bombs/environmental disasters that standard fire and rescue can’t appropriately address with reasonable tools upon crashing, because they inevitably will.
Its a market capitalism problem. Fire, ready, aim because rush the pos to sale. Musk is certainly a standard bearer as a prominent “get government and society’s wellbeing out of the way of my quarterly profit expectations” asshole sociopath capitalist.
I think your feelings toward Elon may be clouding your judgement here a bit. Putting out electric vehicle fire is hard, independent of the brand of the vehicle.
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”.

"alright, is everyone here? this is an all-hands meeting. Where is Joey? Is he in the bathroom again? He’s missed the last 3 meetings… Anyway. Top of the agenda, there’s apparently a fire, right over there. Fires are kinda hot and so we have been sure to stay a good distance away, as to not raise the temperature of everyone’s complimentary bottled water, handed out at this meeting.
Now it says here that we should tackle this situation as quickly as possible. Has anyone run the numbers by the finance team? We don’t want to spend too much on this. The big-wigs upstairs never think about the big picture, and really I don’t see why one fire is worth pivoting all our available resources. Samantha, yes?"
“Sir, the fire is growing at an alarming rate, shouldn’t we just postpone the meeting and focus on the fire?”
“See, that’s exactly the kind of thinking the execs have. But if we spend all our resources, cuts will be made, and jobs will be lost. Not mine, of course, but others. Did anyone do a PR analysis on us ‘putting out this fire’ versus just running a week-long ‘we are sorry’ ad campaign?”
(lol I just got the thought and ran with it)
