Sorry that happened to you MelRay, hope you have a full recovery. As several have said, we really have to be careful. I knew to be wary of burning freon, but had no idea of ammonia being used in RV fridges, good to know. I demolished an ice cream plant once that had huge ammonia systems in it, fortunately, all were discharged.
Another gas to watch out for is chlorine. When I demolished a 2 million gallon tank at a water treatment plant, they had chlorine sensor sirens with windsocks by them and we had to have a training session for it.
