Thank you for the history lesson, a little science, some hygiene, and a dose of common sense. Berney

Interesting article Andy, releasing a balloon load of sulfur dioxide (SO2) anywhere will be quickly dispersed and do nothing ... it's a humongous atmosphere compared to a balloon load of SO2. During college in San Francisco, I found an old refrigerator probably from the 1930's using SO2 as a refrigerant. I knew the stuff was toxic so I released some of the refrigerant ... it will definitely temporarily shut down your breathing if you get a good whiff of the stuff.

My dad in Salem, MA (and where he was born) worked with the Salem Fire Department to go into burning buildings and shut down the air conditioning and refrigeration equipment using toxic refrigerants such as SO2 and ammonia refrigerants. My dad's dad did similar work of removing toxic chemicals nearby a fire. My dad was exempted service in the War because his services were needed by the fire department to go into fires and take care of shutting down or removal of toxic chemicals. One area of work my dad started with was refrigeration work and later got into Radio/Television repair.
