It took 50,000 gallons of water to put out Tesla Semi fire in California, US agency says
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.
I wonder, would some quickly deployable heat barrier to surround it that can be filled with water once work? Kind of like dunking it a pool, except kind of backwards in that the "pool" is deployed around it and then filled?
I'm not sure how you just build a pool that doesn't leak and can hold the weight of the water...
You couldn't build it and get it filled fast enough. Also with a 1k degree battery a lot of that water is boiling off instantly.
Hmm, yeah, good point. What if you throw a bunch of dirt or sand on it from a truck filled with it from a distance until it's covered? Like one of those things that poke up from wood chippers and launches the chipped wood into a higher truck, but redesigned to throw dirt or sand at a burning EV from a dump truck at a safe distance?
