be imported Halon <g>

I suspect that there is plenty around. When you consider that there is no
consumption except in the event of a fire, most Halon extinguisher systems
will outlive the air craft and the Halon will be recovered when the craft
is scrapped. Also, I'll bet the extinguisher folks are hording a bunch and
what's a few thousand dollars worth of Halon when compared to a
multi-million dollar plane.
I once worked for a company that packaged aerosol insecticide. Since most
aerosols use porpane as a propellent, the station where the propellent is
introduced into the can is a very hazardous location. It is housed in a
separate building, no steel tools allowed in the room, and it is equiped
with a Halon suppression system. They had two discharges in the past 20
years (both were false triggers) and they had ehough Halon on hand for
quite 10 or more recharges. A lifetime supply for them, I'd say.
