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.

    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?

      For as much as people want their Musky circlejerks. This is really just a problem with the switch the EVs that people aren’t willing to accept.

      There is no way to really stop an EV battery fire.

      The batteries in these cars are made up of several cells, packed into a watertight, fire resistant box. When just one of those cells goes it’s over. It can create a chemical reaction that can ignite the cells without the need for oxygen, pure heat will set them off.

      The only real way of dealing with them is to let them burn themselves out, and even after that they aren’t safe and could reignite.

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

        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.

        Anyone dealing with batteries would have. It is more common than you think and not just people being keyboard warriors.
