A long time ago(1985) I broke loose some AC fittings on a 76 dart in my gargae during the winter. I had one of those round wick type kerosene heaters sitting on the floor in my 2 car garage which was on, I looked out from under the hood to see a thick black smoke coluum pouring out of the top of the heater the same diameter as the heater. It filled my garage from the ceiling half way down to the floor in a minutes time. Luckly I noticed it before it was too late and got my garage door open and I ran out of there. I felt sick for a while after that.

That was the last time I ever sat anything on the floor of my garage with a open flame, wall heaters for me from then on. It was bad gas fast when the freon got to the open flame. FWIW
