I'd suggest reading .  Halon 
is described as "remarkably safe for human exposure".  Manufacturing was 
stopped in 1994 due to CFCs, so all halon is recycled.  Seems to me there is a 
disconnect somewhere.  Additionally Halotron is the latest "enviromentally 
safe" non-CFC version.

Not sure what the laws are in the US but in Canada, Halon was pulled many years 
ago. It is one of the most efficient fire suppression systems around except for 
the fact the chemical reaction with fire creates a fatal poisonous gas. I don't 
think i would use it in my aircraft.

Just my $0.02 worth.

DJ was kind enough to point out that the Halon extinguisher I advised to order 
was dry powder, not Halon, so I could cancel the order.  Halon extinguishers 
are an order of magnitude more expensive than unit I was looking at on Amazon.  
I should have known.

 Double check that info. Halon in buildings was safe to breathe
 while evacuating the building. DO NOT BE SMOKING THOUGH,

I'm using the RT A400 unit that Aircraft Spruce sells.
Small but unfortunately not cheap.
Currently $ 230 USD each but then worth every penny if I ever have a fire 
emergency in a wood aircraft full of fuel!
Cheers

Look in the engine bilge of most larger boats and you will find a self 
energizing halon extinguisher aboard...maybe two of them.
I am curious if these cylinders are good/recognized for aircraft use. Some 
are large due to the volume of the installed engine(s)
Most are small, weighing a couple of pounds and easy to install, using the 
automatic/heat sensitive valve or a manual switch.
Since a KR area is small compared to an inboard marine installation, a large 
halon cylinder need not be necessary.
They are fairly cheap (somewhat) for boats Experimental eh?

Are you sure on those facts about Halon?
Check out : H3rcleanagents.com.  Site for Halon myths.
No mention of poisonous gas ? Only that it was discontinued in 1994 because it 
is a CFC and depletes the ozone layer.
I'm still using a Halon fire extinguisher in my a Canadian amateur built KR2.

KR> Halon

[Dave Acklam]

Halon 1301 does turn toxic IF exposed to extreme temps and is thus not
reced for class D (flammable metal) fires

But if not being used on something like thermite or magnesium Its one
of the safest room-flood fire suppressants out there.

The bans are due to it being a CFC, not due to toxicity

The 'halon' found in portable extinguishers is a different formulation...

And of course CO2 exposure will kill you faster than either (oxygen
displacement)
