Hi all,

I was hoping somebody could help us out on an SO2 exposure issue. A few weeks back we had a faculty member defrosting a freezer in the lab. This was an old freezer (circa 30‰??s/40‰??s), and he was defrosting it to donate it to the theater department.

Long story short (too late), he ended up rupturing the coolant line, and all of the coolant released from the compressor. Turns out the coolant was SO2. He left the room soon, but he did get in some big breaths. He didn‰??t seem to form water in his lungs at the time (he did go to the doctor immediately). He still has a taste of sulfur, and he‰??s developed a rash that he feels is due to the exposure. Three weeks later he is still showing some symptoms, and so we are just trying to evaluate what he should do and how to handle this.

Any thoughts would be helpful. Thanks

Dave
