On August 19, firefighters in California used about 50,000 gallons of water to put out a fire caused by a Tesla Semi truck’s battery after a crash on Interstate 80 near Emigrant Gap, about 70 miles northeast of Sacramento. The fire was very intense, with the battery reaching temperatures as high as 1,000 degrees Fahrenheit. To help stop the fire from spreading, firefighters also used a plane to drop chemicals. The crash happened around 3:13 a.m. when the Tesla Semi, which was being driven by a Tesla employee from Livermore to Sparks, Nevada, went off the road, hit a tree, and caught fire. The National Transportation Safety Board (NTSB) is investigating the fire risks of the truck’s battery and confirmed that Tesla’s automated driving systems were not on during the crash. Firefighters closed the freeway for 15 hours to cool the battery and then monitored the truck for 24 hours to prevent the fire from restarting. The NTSB will keep investigating and provide safety recommendations for handling high-voltage battery fires in electric vehicles.
