Lithium reacts with water. You’re supposed to use foam not water to extinguish a lithium battery fire.

Makes sense. Foam was used to put out magnesium aircraft wheel fires.

Lithium-ion battery fires are not the same as lithium metal fires.

You need to get in touch with NFPA and have them modify their recommendations.

No. Foam actually insulates and increases the temperature.

"...You’re supposed to use foam not water to extinguish a lithium battery fire."

Not according to Tesla. Their instructions say specifically to use water, not foam. And foam DEFINITELY won't put it out because the source of the fire is the heat from dead shorts between adjacent battery cells. Depriving it of oxygen is pointless.

The objective of the water isn't to deprive the fire of oxygen, it's to cool the batteries to below the auto-ignition temperature of lithium. Which is problematic because the batteries burn so hot, and are buried so deep in the chassis, that most of the water is converted to steam before it reaches where it could do some good.

The Euro-Weenies have found that the best way is to send a dumpster full of water (a swimming pool on wheels) and a crane rather than fire trucks. They pick the car up and drop it in the tank of water. The standing water gets down deep into the chassis and is of large enough volume that it doesn't all boil off before the batteries are cooled.

Here they are preparing to drip a BMW i8 into the water tank:

And here's the same car once it was in the water:

No more burning Bimmer.

The Drive has a story on the incident depicted here:
