I remember about 12 years ago or so a firefighter said they had some trucks with foam instead of water to fight potential hybrid fires. And recently a dispatcher told me they will often ask what type of car you have in the event of an accident. And now we get a dedicated truck because EVs tend to become barbecues. Often in parking lots
Toyota Hilux 6×6 fire truck was built to fight EV fires
With more electric vehicles on the road, EV fires have received a lot of attention in the news. High profile blazes like damaged battery packs spontaneously catching fire in the wake of Hurricane Ian and an entire cargo ship of EVs going up in flames have prompted one U.K. company to create a fire truck specifically designed to fight EV fires.
York-based Prospeed Motorsport fashioned a fire truck out of the globally popular Toyota Hilux pickup because of its compact size. EV fires often break out in places that are hard to reach with conventional fire-fighting vehicles, like underground garages or multi-story parking structures. They’ve named it the Hiload, and made sure it has a 1,850mm (72.8 inches) height so it can clear height restrictions in urban carparks.
Additionally, EV fires usually begin with battery packs that are damaged internally. The catch is that they’re usually housed in difficult-to-reach areas of the car. The Hiload carries a ColdCut Cobra fire suppression system that uses an “ultra high pressure lance” to shoot abrasive material suspended in water at 4,350 psi. The liquid spear breaks through the battery casing so water can be sprayed directly into the modules.
In theory this will limit “thermal runaway,” the phenomenon where damaged lithium-ion batteries heat up very rapidly in a chemical chain reaction to high temperatures that can be very difficult to put out. Firefighters in some cases have had to keep EVs submerged in water for days. The ColdCut Cobra system is said to be able to squelch a fire with just 60 gallons of water.
Again, I’m not against EVs. I am against forced mandates. And this tells me that all these mandates in the 1st World are a Bad Idea when you need a special truck to deal with not only fires from accidents, but, because they spontaneously catch on fire, and regular trucks cannot put them out. Nor could fire suppression systems in parking decks (you can see a system in the above photo), which tend to use water, foam, or dry suppressant. But, cannot really handle the extreme temperatures nor be able to get to the battery systems.
Oh, and the irony of using an ICE (internal combustion engine. I’ve seen this acronym cropping up a lot more of the past week) to put out an EV fire is delicious.
