Sulfur dioxide is a very active and unstable gas, borrowing an oxygen atom from where ever it can get it to become sulfur trioxide and your lungs are a great source of the moisture to supply the oxygen atom to do this chemical magic. Another more common name for sulfur trioxide is sulfuric acid. Not a pleasant way to go out, and a lot of people did back in the days of the monitor top home refrigerator which used it, likewise the propane fired mobile home/camper fridges yet today. One molecule of water in such a system kept being recycled into acid and eventually ate a hole in the plumbing, in 20 years or so. Its a very efficient refrigeration gas, beating ammonia and all the freon's.
