Random thoughts about battling lithium-ion battery fires---

* The recent Tesla accident near Houston, firefighters used at least 32,000 gallons of water to extinguish the flames. Firefighters at the scene contacted Tesla for advice on how to extinguish the blaze and were told just to let it burn out.

* 32,000 gallons of water weighs over 132 tons.

* Average fire truck holds only 500 gallons of water.

* Tesla's Emergency Response Guides excerpts--

FIREFIGHTING

USE WATER TO FIGHT A HIGH VOLTAGE BATTERY FIRE. If the battery catches fire, is exposed to high heat, or is generating heat or gases, use large amounts of water to cool the battery. It can take approximately 3,000 gallons (11,356 liters) of water, applied directly to the battery, to fully extinguish and cool down a battery fire always establish or request an additional water supply. If water is not immediately available, use dry chemicals, CO2, foam, or another typical fire-extinguishing agent to fight the fire until water is available.

Battery fires can take up to 24 hours to extinguish. Consider allowing the battery to burn while protecting exposures.


Houston, think we may have a problem.....

OTOH, I have seen liquid fuel running down the street burning. And seen the fire start a block from the wreck. If the battery stays in 1 place that could be a plus.

Of course that could depend on where that 1 place is located, like a parking garage. Car fire would be bad, gas or electric.

Yes, a battery fire in 1 place in a parking garage would be bad. But what about burning gas flowing across the floor of that garage?
Back in early '70s a wreck started a car fire a little east of you.(92&169) I pulled up next to the truck in front of me, and we both grabbed our extinguishers, ran up and made sure everybody was out of the cars. As we walked back to the trucks we watched fire come from behind our trucks. Gasoline from the car that was not burning had ran down the hill, and somehow got ignited.
Back when everybody drove hayburners, the main firefighting technology was a stack of buckets. When batteries are more common likely be advance in that tech

My question is how toxic and what sort of gases are released from a battery fire?

I think we are talking about a vehicle collision occurring on the highway/freeway at high speeds (like Tesla accident smacking into a tree near Houston). When an IC smacks a tree at high speeds, the fiery explosion will usually cause the gas tank to explode...unlike the explosive scene from Die Hard where Bruce Willis blows up the airplane by simply igniting the leaking fuel during takeoff.

I wonder what happened the 32,000 of contaminated water (enough to fill an 32' x 40' swimming pool) the fire department used? Bet it went down the drain and into a waterway--right where us fishermen fish and our children play. Can we say "ecological disaster" caused by those who are "ecological minded souls?. What a conundrum we have here.

Fwiw

All new Tesla have improved fire resistant battery packs filled with flame retardant so fires shouldnt be a problem.
Buy new Tesla not old used one.

I can remember several deadly and/or destructive truck fires. Every battery powered vehicle on the road helps displace another tanker.

The fear of the new is almost always worse than the few of what we have lived with all of our lives, whether deserved or not. When reading the instructions for dealing with a Tesla fire keep in mind that virtually consumer or pharmaceutical has warnings about the product causing injury or death. In California anything cooked on grill has to carry a cancer warning.
