You sure they weren't talking about phosgene, the stuff you create if you MIG/TIG over brake cleaner?
R12 is R12, no matter whether it's in a sealed, pressurized system or floating around in the atmosphere. In fact it's completely inert, nonflammable, and nontoxic. The reason it was phased out of production was because it is extremely damaging to the ozone layer, like all CFCs.Comment

No its once it gets boiled and turns into a vapor that it gets to that. The chemical gas it turns into is comparable to agent orange. Thats just what instructor said. He could be wrong but he's been there for quite a while so would think he knows his stuff

Interesting. I worked as a refrigeration engineer for years, and I have both my RETA-CIRO and EPA Section 609 certs. In all of my years I've never heard or read anything about R12 (or any CFC refrigerant) turning toxic. In fact that's why CFC refrigerants were invented: as a safe and nonhazardous alternative to other refrigerants such as H2, NH3, etc.
It was even used as a propellent in medical inhalers, Silly String, and other aerosol-based products. If the gas or vapor were poisonous, there'd be a lot of dead patients/kids/painters. https://en.wikipedia.org/wiki/DichlorodifluoromethaneComment

You make a valid point. Its entirely possible he is wrong and could of mis interpreted that for something else. He is an old man and admits it.Comment

Agent orange is a combination of herbicides. Has nothing to do with r12.
The only thing toxic r12 does is release chlorine gas when it's struck by UV radiation, but that doesn't happen until it's in the upper atmosphere.

it's time for the bi-annual update!
scored a pretty clean front subframe from wworm, stuck it in the parts washer and sandblasted relevant areas in prep for motor mount and sway bar reinforcements.

these plates went in first:

these followed:


I like to finish these seam welds:


sway bar mount reinforcement brackets also went in but I forgot to take photos of those.
stay tuned for the next update, in March of 2018!Comment
