My brother Rick has the exact same cannisters 24/7. He had worked for a floor sanding company in the 70's and an asbestos removal company in the 80's. Now at 49 he can't breath at all without the O2. He was macho and didn't use all the safety equipment that was available I guess. So, Mike, I feel for you and understand what your going through and know what Bob means about the equipment.
the problem with the whole thing is you cant see whats happening to your lungs and it takes 40 yrs. (in most cases) to show up and then its to late.
