Ben,
Thanks for the Halon web site. I wondered why its sale and use has become
restricted.. the following from that web site seems to be the explanation:

How Damaging Is Halon?
A compound�s ability to destroy ozone depends on many factors, including the
amount of chlorine and/or bromine that it contains. To aid them in comparing
compounds, scientists have developed a relative scale called the ozone
depletion potential (ODP). Common refrigerants, like those found in your
refrigerator and in your car air conditioner, have been assigned the value 1
as a reference. Halon 1301 has the value between 10 and 16, meaning it has
10-16 times the more potential for destroying the ozone layer.
