At home I have a halon bottle next to the pellet stove, another near the 
kitchen and a third in the bedroom.  My truck has one in the tool box and I 
need to put one in my wife's Highlander.  She has been thru training... boy, 
how did we do that without any drama?  The most curious one is the small 
halon bottle from the lavatory trash recepticle of an MD-81.  It was made by 
Walter Kiddeof Wilson, NC.  Total weight is 388 gr. and the "CBr F3" weight 
is 105 gr.  It is very ingenious in that it has two 1/8" dia tubes which 
point down into the trash bin should anyone get caught smoking and throw a 
still lit butt in there and start a fire.  The agent is released 
automatically as the two 1/8" tubes are closed with a solder of some kind 
which likely has the perfect melting point to release the gas just in time 
to prevent a big lav fire.  I removed it from the aircraft at the bone yard 
in Mojave just before the hulk was to be cut up for scrap.  I have been 
looking for a place to put it where its small volume would do some good. 
Under my truck hood is the best I have come up with so far.  Maybe behind 
the panel of N990Y would be better.
I think halon will displace just as much oxygen as Co2.  I would like a 
medical/chemical explanation why halon might be more survivable, all else 
being equal.
Great subject.
