Subjected to a catastrophic mishap recently, a Tesla Semi prototype caught fire while it was stationed in California. The incident is a stark eye-opener today, not just about the vulnerability of electric vehicles, but also the additional challenges it brings to the table during emergency response operations. Remarkably, it was reported to take an overwhelming 50,000 gallons of water to extinguish the fire that engrossed the electric semi-truck.
In the early hours of November 23, 2021, the California Highway Patrol reported a Tesla Semi prototype was completely devoured by a fierce fire at the Frito-Lay facility. Tesla had allied with PepsiCo-owned Frito Lay to test its semi prototypes. Unfortunately, the catastrophic event had taken place while the Semi was parked at the Frito-Lay facility in Modesto, California.
While the initial cause of the fire remains undetermined, it was severe enough to attract the attention of several fire departments to the location. The stout response team included the Ceres Fire Department, Turlock Fire Department and the Modesto Fire Department. It is pertinent to observe that it required their coordinated efforts to handle the crisis effectively given the unique context of an electric vehicle.
Among the several challenges that these unfortunate instances pose, the one of primary concern is the amount of water required to put out the fire. A press release from the Modesto Fire Department reported that it took a staggering 50,000 gallons of water to control and extinguish the fiery flames. For comparison, an average American home uses about 100,000 gallons of water in an entire year.
This shocking volume of water was mainly necessitated due to the truck’s Li-ion batteries. Once these batteries catch fire, they can reignite multiple times even after the initial flames have been put out. This phenomenon, described as ‘Thermal Runaway,’ can potentially lead to a series of explosions. Hence, it was crucial in this scenario to ensure the battery pack was entirely cooled down to avert potential re-ignition, which in turn drove the need for such a massive quantity of water.
Another challenge that stands out in such incidents is the likelihood of hazardous chemicals spilling from the vehicle’s battery. With electric vehicles gaining increased traction in our world today, it’s imperative to construct comprehensive contingency plans that also encompass measures to prevent environmental contamination.
The incident in California draws attention to the broader need for updated regulations and more technologically advanced firefighting measures that can handle these novel fire hazards posed by electric vehicles. During the incident, the fire departments used drone technology for thermal imaging to track the hot spots of the fire. This innovative approach of incorporating new technology offers potential solutions for similar events in the future.
Investigations into the cause and aftermath of the fire still continue at the moment. Tesla, along with the local authorities, is taking the lead to evaluate the full spectrum of the incident. As a critical player in the EV market, lessons from this fire can have far-reaching implications for Tesla, other auto manufacturers, and emergency agencies that need to prepare for this new era of electric mobility.
The unfolding of this incident ultimately underlines the urgent attention that needs to be put into further research and strategic planning to tackle similar threats in our increasingly electrified world. While the march towards green energy and EVs is an undeniable requirement for a sustainable future, incidents like these should serve as essential wake-up calls to the complexities and challenges they bring forth.
