“Haha EVs are so dangerous! Look at the fire hazard” like you aren’t literally parking a tank of explosive gas in your house every night

Just to be pedantic, the real issue there is that EVs are potentially more explosive, and once they've caught fire, pouring water on the makes them explode a second time.

Do gasoline fires go out with a douse of water?

Nah I think it makes them worse

Sure, and that's one I hear, but it's blown out of proportion by them. Really whenever you store that level of potential energy in any form it's going to be dangerous.

Pouring water on lithium-ion battery fires is not only safe it's the primary means of fighting them. It does not make them explode a second time, what it does do is cool down the battery.

Lithium battery fires though, there you'll want a class D extinguisher. Those batteries aren't in EVs though.

So don't use water? I mean, don't use water in basically any situation regarding a fire anyway, it's a last resort, but if you don't have a fire extinguisher in your home you're asking for trouble eventually.

Tbf if an EV is burning you probably need an electric fire extinguisher, instead of the normal type thats for more common fire fuels.

If an EV is burning, you often let it burn and make sure it doesn't spread to anything else.
