Actually Halon is heavier than air. One of the reasons it is a good extinguishant as it falls to the source of the fire. The recovery action for reviving a person who has passed out due to hallon inhalation is to invert them. The hallon literally falls out of the lungs - conventional CPR can then be carried out.
However it does get up there eventually and is a known ozone depletor
