The National Transportation Safety Board (NTSB) published a preliminary report on the investigation of the fatal crash involving the electric vehicle Tesla Model S. The accident occurred on May 8 this year in Florida.
It was found that three seconds before the collision the car moved at a speed of 116 miles per hour (over 186 km / h). On a site where the speed is limited to 25 miles per hour (40 km / h), the driver failed to control and crashed into the fence, after which the car caught fire. Two people died on the spot, the passenger sitting in the back seat was injured and taken to a local hospital.
During the investigation was established that fire extinguishers consumed about 900-1400 liters of water with foam when extinguishing the Tesla Model S. Just in case the rescuers poured even a breakaway fragment of the lithium-ion battery, although it did not burn.
But, as it turned out, the above measures were not enough. During the loading of the burned-out electric vehicle to the tow truck, the battery in the car again ignited. The fire was quickly extinguished, but it was repeated again when the car arrived at its destination. Thus, accidents involving electric vehicles require special attention from firefighters, although incendiary fires are also common for conventional cars with internal combustion engines. The investigation of the incident continues.
