I was at a sale last weekend that had blacksmithing things and the seller had a gas forge to sell. As I looked around his shop, I noticed buckets and racks with all kinds of galvanized and chrome bars, rod, pipe, etc amongst the other material. I round about asked him what he made and if he used this stuff. Yes, of course he did and I tried to impart what I knew about the dangers involved in using it, even pointed him here, but he wasn't interested as he said he wheeled his forge out into the driveway and "knew all about that stuff". Long story short, he asked me to leave.
I have been wondering if that forge would be safe to use if someone bought it not knowing what it has been used for. Would it continue to emit particulates and bad fumes, etc.... Or would it just all be vaporized or just "go away" after use?
