I have personally worked with scientists from the University of Wyoming and

measure the ozone hole and the chemicals that are harmful to ozone (CFCs,
Bromine compounds, etc.) I have helped launch balloons and collect telemetry

are nifty compounds at ground level for lots of tasks (cooling, cleaning,
etc.),
at 30,000m, they are not a) natural and b) harmless.
At McMurdo, in spaces with electrical equipment, rather than Halon, there are
built-in C02 fire-supression systems. They are much larger physically, and
harmful to humans, but CO2 poisoning vs. Halon suffocation leave you just as
dead.

I've heard that Freon...isn't nearly as
dangerous as it's made out to
be, and that the recent legislation to have it banned came about just after
the patents expired
It isn't patents, it is the CFC treaty (Osaks?) that bans the production
(first) and then use (second) of CFCs based on their alleged, but unproven,
impact on the ozone layer surrounding the earth. Note that I do not dispute
that there is a gap in the ozone layer around the earth, only that no one
has yet given anything more than conjecture on why it exists, and since we
don't have historical data on its existence (or lack thereof) we don't yet
have anyway of proving or disproving said conjectures, but something that
_was_ a provable way of saving _actual human lives_ was banned because of
it. </soapbox>
