Federal regulators warn of risks to firefighters from electrical vehicle fires
Lithium-ion batteries pose a unique threat, and most first responders are not prepared.
“What the heck? How do we make this stop?’” Buck asked his team. They quickly consulted Tesla’s first responder guide and realized that it would take far more personnel and water than they could have imagined. Eight firefighters ultimately spent seven hours putting out the fire. They also used up 28,000 gallons of water — an amount the department normally uses in a month. That same volume of water serves an average American home for nearly two years.
By comparison, a typical fire involving an internal combustion car can often be quickly put out with approximately 300 gallons of water, well within the capacity of a single fire engine.
As the popularity of electric vehicles grows, firefighters nationwide are realizing that they are not fully equipped to deal with them. So they have been banding together, largely informally, to share information to help one another out. In fact, Buck recently spoke on Zoom about the incident before a group of Colorado firefighters.
That’s because the way that electric vehicles are powered triggers longer-burning fires when they crash and get into serious accidents. Electric cars rely on a bank of lithium-ion batteries, similar to batteries found in a cellphone or computer. But unlike a small phone battery, the large batteries found in the Tesla Model X, for instance, contain enough energy to power an average American home for more than two days.
