While trolling around looking for info on welding cast iron, I ran across this little spooker!

I read this a few months back. And to think we used to hunt freon leaks with one of those propane sniffers that the flame turned funky colors when it found a leak. Guess what gas burning freon makes....deadly phosgene!!!!! Be careful if you play good samaritan on a car fire!

The brake clean I use is made by Penray and is still acetone based! smile Cleans better than the newer stuff out there as well. If ya have a local Cummins dealer thats where I buy it. Usually cheaper than the auto parts store too!

actually many man made materials produce phosgene gas when thier are burnt. all the lovely carpet, foam filled chairs, and plastics out there used in your homes and cars are likely to produce phosgene.

One of the guys I worked with was burning a bunch of stuff from an old mobile home he was cleaning out, the wind changed quick and he got a lung full of smoke. Two months later he got out of hospital, six months back to work. He was Very lucky

The risk of phosgene gas is only present in "chlorinated" brake cleaner.

its just a good idea to stay out of the smoke plume from ANYTHING that you weld or cut.Back in the day welders didnt pay much attention to poisoning; but nowdays there are much more plastics and chemicals in paints+coatings on metals to deal with,especially the used metal we all like to use...clean it off the best you can before you operate.Just a couple of minutes with a grinder and sanding disc.get one dose of zinc fume fever and youll know what I mean

I learned about Phosgene gas when I took a welding coarse twelve years ago.

You can also get it by welding a painted surface. The burning paint will release it. Also if the paint has lead in it. You will have additional problems.

Always wear a respirator mask with charcoal when welding. No matter how small the job is. Weld in a well ventilated area.

The other side effect is nerve damage.
