Great web site !  I am learning allot.  I was diagnosed last year after being sick.
I tried a search but did not find anything about running high speed floor burnishers on wax covered tile floors. I did this for a number of years and always wondered how good running a propane floor buffer was for the lungs. 
I’m not blaming. I also smoked for 38 years and am  taking meds to help me quit. I have yet to set a date. Was about to and had a few bumps with the other meds I’m on and some stress for a few days.  But I am determined to fight the butts !!!!!!!!!!!!
