Before going to the added operational requirements necessary for using an
FFM for deco, consider the pros and cons of using EAN80 in place of O2. The
PPO2 at 20' is 1.28 and it makes very little difference in total deco time.
A lot of people will jump on me for recommending EAN80, but since we're
trying to be as safe as possible, I believe EAN80 is a viable alternative
for the open ocean, especially for those concerned with high PPO2's.  The
down side, well its not as easy as transfilling from a bank of O2 bottles
and there is probably an increased explosion hazard because you have to put
high pressure air on top of O2, although I've not heard of this happening
anywhere yet (I'm sure George will tear me a new one for speaking this
nickelrocketry-technoweenie-tomfoolery, but I've been a little constipated
lately, so this may help!). -  Tony
