Sgygus: Does it kill cancer?
RY28: In before AC newbies start talking about making phosgene gas.
Lukeonia1: I already knew (from experience, no less) that any fluorinated refrigerant produces hydrofluoric acid and carbon monoxide when it burns. SAE says this new stuff is only slightly more flammable than the old R123a.Is it possible the design of the car's air conditioner system might be part of the reason for the nice dramatic fire in the article?/daily fail, indeed
Riche: Totally worth it.Have you ever driven a black car anything in the southwest during the summer with no A/C?
Cybernetic: Wiki says that when it burns, it releases hydrofluoric acid--which is truly scary stuff.
Dr Dreidel: Also, a refrigerant that burns is doing it wrong. You had one job, REFRIGERant...
skozlaw: But when McCarthy gave SNAP approval to HFO-1234yf, her office never mentioned the tests conducted by Daimler, the parent company of Mercedes-Benz.Yea. Probably because Benz is the only company that's ever managed to actually produce that problem in all the tests that have been performed.It's almost as if they created a test with a desired outcome to avoid having to begin using a product that's significantly costlier than the one they've been using...
hitlersbrain: I feel that cars should explode more. I can't remember the last time I saw a car explode like they do in the movies. I will be better able to defend my home and family if I can make the bad guys cars explode when I riddle them with gunfire like they do in the video games.
Ivo Shandor: Fun bit of trivia: many of those "canned air" dusters are the same R-134a chemical that's used as a refrigerant. If it's inside an air conditioner you're supposed to carefully recover and recycle it. If it's in a duster can, spray away!
palan: Cybernetic: Wiki says that when it burns, it releases hydrofluoric acid--which is truly scary stuff.I don't think I've ever heard about a fluoride compound that isn't incredibly scary.
Kraln: Man, fluorine compounds are super nasty. To give you an idea, Fluorine will bind with noble gasses--yeah, you can have NeF8. Why the hell would you put fluorine anywhere near a car?
palan: I don't think I've ever heard about a fluoride compound that isn't incredibly scary.
YoungLochinvar: Teflon scares you?
skozlaw: R-134a is not dangerous unless it's compressed in which case it can freeze your skin. Aside from it displacing oxygen, there is no reason it wouldn't be safe coming out of a duster.
Although the product is classified slightly flammable by ASHRAE, several years of testing by SAE proved that the product could not be ignited under conditions normally experienced by a vehicle.
