Stumbled across this article on the 67-72 forum and thought it was worth sharing. I'll admit I am very naive when it comes to welding fumes but this was eye opening. Worth the read if you do any welding, might save a life.

From my understanding, chlorinated solvents have long since been discontinued (1996?). I could be wrong though and I guess there could still be some old stock floating around, or methylene chloride used in paint strippers may pose a problem
And this has been discussed here too: http://www.duramaxdiesels.com/forum/...light=Phosgene

Welding galvanized steel is a big no no too unless you can stay out of the fumes

Any of you guys that weld a lot or by profession wear SCBA or use HEPA filtered air from a pump?

Every shop welder at my mine wears a battery operated ventilated helmet that draws air from the lower back through a filter system for all welding even just mild steel. They only go under supplied air if welding in confined spaces. |

Also, in case you didn't know. HEPA is a particulate rated filter and not suitable for fumes. So almost useless for welding.
Ok for use when drawing air from a clean (fume free) location though

AZ still sells chlorinated but i learned in Auto, back in high school, just how bad it was for you so ive never bought it. Since i dont TIG, i dont brake cleaner to spray anything off. if its dirty, it gets cleaned up with mineral spirits and dried. Certainly shouldnt be doing it while the weld is still hot.

Look closely at Brake cleaner. A lot of it is still chlorinated and if you read the article, that is what the welder used. I know they make an un-chlorinated brake cleaner, but out of habit, they recommend using acetone to clean the parts to avoid the possibility of using the wrong brake cleaner.

We always use acetone to clean with. Welding shop is Tig only and highly ventilated. Be careful out there guys, you only got one set of lungs.

I learned this the hard way, as Idaho still sells chlorinated brake cleaners. I always get them as they work way better. I thought it had all evaporated, but apparently not, because after a few minutes welding, felt like I couldn't breathe and went outside. Found that exact article while I rested, and realized how lucky I was that most of it had evaporated first
![]() I don't weld enough to justify getting one of the fancy ventilated helmets, but this made me think really hard about it. Now I use acetone or non-chlorinated cleaners, then ensure it is completely dry before welding. If I did it for a living, I would totally invest in a ventilated helmet pack. |

Lol I only buy chlorinated products... they work WAY better!
Wish I could still buy the old carb cleaner that was only for sale in like 6 states but the epa shut them down and now it’s pretty much impossible to get clean a carb unless you got a sonic bath of some sort As far as welding I do that every day all day Galvanized sucks but all you do is make sure your not face right in the smoke and drink some milk Had metal fume fever a couple times but it’s not that bad ![]() Hard facing rods have a lot of chemicals in them that no matter what you do your going to get a headache so I don’t like doing that much
