Recalling Avogodro's law, Isn't Halon also heavier than air?
In fact, isn't it heavier than CO2?

Well, I don't remember. I know it's typically discharged from the high point
in an enclosed space through specially designed diffuser nozzles, so what
you say may be correct. I seem to remember that, like air, it is a
homogenous mixture of gasses and tends to diffuse throughout the atmosphere.
Maybe that's why some are concerned about the "Ozone hole" and Halon
affecting that in the upper atmosphere.

It's been a long time since I've studied any basic chemistry and I didn't
know that much about it then. If different gaseous elements tended to
separate out, wouldn't Nitrogen separate from Oxygen in the atmosphere? But
we know it doesn't. I don't know enough to hold up my side of a technical
discussion based on Avocados. I remember that we used to put sniffers at
different heights inside buildings where we were discharging Halon systems
and would measure the concentration at all levels.
