Thanks for the post. I just ran out of carb cleaner and was going to use brake cleaner to remove the cutting oil before welding my x brace in. |

WoW! I use brake cleaner and Laquer thinner to clean joints before welding. I let them dry before I weld however only because they are flamable. I did not consider the toxic aspect. I know that Galvanozed steel is pretty toxic to weld so limited exposure for sure. |

In my trade (HVAC) R-22 freon also causes phosgene gas when it comes in contact with fire. I had a similar experience soldering a unit in, but not as bad.... |

Old school mechanic told me they used to check for freon leaks with a propane torch and some sort of tube. Get the tube around a freon leak and it would siphon the freon into the flame A leak turns the flame green. |

Yep ,thats the old school way to check for leaks. Although its not in production anymore, R-22 has hydrogen and chlorine in it and will turn into a nerve gas (phosgene) when comes in contact with flame....you know people used to sniff freon to get high. |

Used to? They still do. About 2-3 puffs of R22 will knock your socks off if not kill ya. |

Very lucky indeed. I did find some information about some brake cleaners that have Tetrachloroethylene in them. It seems that Tetrachloroethylene are in all the NON-flammeable brake cleaners. With that said, NIOSH recommends that tetrachloroethylene be regulated as a potential human carcinogen. Below is the first responder information on tetrachloroethylene: http://webwiser.nlm.nih.gov/getSubstanceData.do?substanceID=207&displaySubstanceName=Perchloroethylene&UNNAID=&STCCID=&selectedDataMenuItemID=1 |
