I know it's unlikely to happen but everyone that ever uses a torch or welder should be aware of this. I was unaware of the Phosgene aspect but my Oncologist was 95% sure that tetrachloroethylene was the cause for me getting cancer. Just a friendly reminder to be careful when using chemicals and read the MSDS sheets when they are available(all are available on line). OK off my soap box.-Jake
