Sorry but yes JackHerer. We use it all the time but in this application we flood the room. C02 is heavier than air and can fill a room and sufficate you just as bad as carbon monoxide. We have had many warnings about using it in a people living area. We must watch heavy gasses closely. I had at one time N20, nitrous oxide which is a heavy gas too. 3 friend opened the tank in a bath room and I barely got back in time to save thier lives. Just a heads up, NO SLAM. I don't want anyone hurt or killed. Be carefull people.
Anyone else want to back me up on this or tell me I'm wrong and there's no hard feelings here.
