Re: Halon

Unfortunately, Dale, it ain't so harmless. How about some cancerous Aussies
to begin with? I wish it wern't true, because, as you see from my other
posts, I love halon as a fire extinguisher.

Easy: for the same reason water vapor (molecular weight 18) doesn't all
stay at the surface of the earth, but is part of the mixture of Oxygen (mw
32) and nitrogen (mw28) and carbon dioxide (mw 44). Small- and large scale
turbulence mixes the stuff to the molecule level and at that level, the
rate of descent due to weight is so small that it is irrelevant compared to
the vertival movement of the air masses.

Nope, hardly any halocarbons, just halogens. But they have a hard time to
make it up there for chemical reasons. (See what Don Royer sais).

You can blame the government (any government!) for a lot of things, but
hardly for facts <g>.
