Sulphur Dioxide (S02) is nasty stuff. The pulp mill I worked in years ago made sulphuric acid out of raw sulphur and S02 was a byproduct. We needed respirators nearby at all times in case of a leak and any shiny pennies in your pocket would turn black by the end of the day if you were exposed to it. I can only imagine what it would do to your lungs.
Yes, they manufactured refrigerators and I think an oil fired water heater.
