As lawmakers around the world weigh bans of 'forever chemicals,” many manufacturers are pushing back, saying there often is no substitute.

One of their uses is in firefighting chemical fires.
When an electric car is on fire, you need PFAS to stop the lithium fire. Water just can’t stop it.
Of course, before batteries we used gasoline.
I imagine their might be more of these cases where modern technology relies on unsustainable practices.
Just because PFAS is one way doesn’t mean there aren’t other things that would work.
I really hope there are others. I haven’t heard of alternatives yet.
So for electrical fires, they use carbon dioxide to smother the fire and sodium bicarbonate to aid in putting it out, along with class c fire extinguishers. Class c are just carbon dioxide.
For chemical fires, carbon dioxide extinguishers are also used. They can use extinguishers with bromochlorodifluoromethane, aka Halon 1211, (which I guess could be a pfas chemical, but I don’t find anything either way).
Electrical fires don’t generate their own oxygen.
Good thing a lithium fire isn’t an electrical fire then, isn’t it?
I don’t know that it is a good thing. It just means you can’t use baking soda to out it out.
Well, normal electric fires don’t but, as @Vodik_VDK@lemmy.world already quoted, lithium-ion battery fires do generate their own oxygen
That was my point to. I guess I wasn’t clear enough.
Regulate it and the ev car manufacturers will spend the money to find one.
Wouldn’t it just be better to cure cancer? Why don’t the scientists just do that?
The big one is airplane fires, AFFF is the best foam for putting out a jet fuel fire.
Sand. You use sand.
