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.

How much is this in Capri Suns?

[–] [email protected] 4 points 2 months ago (1 children)

There's 5 200ml Capri Suns to a liter. At about 190,000 liters, we're looking at about 950,000 Capri Suns.

Maybe don't use water to put out a fire that can't be put out with water. Aren't these supposed to be professionals?

How many lithium ion battery fires have you put out?

[–] [email protected] 9 points 2 months ago* (last edited 2 months ago) (1 children)

Two.

The best policy is to not puncture batteries, and train others to not do so.

The next best is to know to smother them.

[–] [email protected] 12 points 2 months ago (8 children)

how do you smother a semi fire on the highway, a) with a water tanker or b) with a sand tanker, how many municipalities have a sand tanker on hand, how do those sand tanker hoses work again, lots of sand tanker slingers round your parts cowpoke?

Flooding the batteries with water is the best way to put out a lithium-ion battery fire.

Isn't oxygen deprivation (usually through burying) a much faster method?

[–] [email protected] 24 points 2 months ago

Maybe for smaller things, a regular car maybe.

But by the time a suitable digging machine arrives on scene and digs a big enough hole for a semi it'd probably be faster to flood it with water. Not to mention what might be underneath the ground, so they'd also have to spend time determining if there's any gas lines or whatever before they dig so they don't make a much bigger problem

Do you volunteer your backyard for such burials?

Probably only shows up that way on lemmy.ml, which has a blocker for various things they consider slurs, which can become silly when you're dealing with words/phrase like "fire retardants." Looks normal to me over on blahaj, and the same over on lemmy.world

Is this 190 tons of water?

[–] [email protected] 23 points 2 months ago* (last edited 2 months ago) (7 children)

189.27 metric tons of water, so yes, rounded up, 190 tons.

Or roughly 2.5 average swimming pools and for those ex-redditors out there: 1.6 million bananas

Something tells me that we have to move away from cobalt/manganese chemistries for BEVs.

Solid state batteries are supposedly much more fire resistant.

[–] [email protected] 5 points 2 months ago (1 children)

Even the currently available LFP is much less violent.

[–] [email protected] 3 points 2 months ago

Yes, true. Albeit they have worse energy density and some advantages as well.

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

[–] [email protected] 23 points 2 months ago (1 children)

Our town...

Do you mean Babylon, Marduk?
