As it happens, there has been some recent and animated discussion on the aviation forums as to the usefulness and operation of various types of aircraft fire extinguishers.

After some research I came to the following conclusion:
1. I cannot reach the extinguisher we have in its back seat location;
2. Even if I could, operating the extinguisher in the confines of the aircraft in flight would likely incapacitate the pilot and passengers.
3. Dry chemical extinguishers cause a lot of aircraft damage.

In addition, I need some additional form of securing my O2 bottle which as i use it, hangs in a purpose built bag on the back of the co-pilot's seat.

So after more research, our AME and I came up with a working solution for a three person configuration:

1. Wedge a block of semi rigid foam in the right rear passenger foot well.
2. cut a hole in the foam in which to cradle the bottom of the O2 bottle.
3. carry a second 1.2 lbs aviation model Halon 2122/1301 extinguisher (H3R RTA600) in a second hole in the foam right where I can easily reach back and grab and deploy the extinguisher.

There is no permanent installation involved.

I bought all the components and will install them for my trip this summer. I'll apprise you of progress.

1) I hope you never need to use the Halon
2) If you ever need to use the Halon, make sure you're sucking the O2 before you deploy
