> Hydrogen seems to me as a great gas to use as Nitrogen substitute, cheap, no
narcotic effect and similar to Helium in decompression. All for one thing, you
can only have max 4% Oxygen in the mix or it will be too explosive and might
self combust. With only 4% O2 it will make it a very deep mix and probably out
of most divers' alternatives for mixes. Now I was wondering if you could use
some other gas to raise the oxygen percentage in the mix without making it
totaly unsafe to handle and use. I'm not the best when it comes to chemistry
but can't you somehow bind the H2 molecules with another gas? If anyone have a
clue please tell me! Alexander

  That will turn the hydrogen <into> another gas (e.g methane (CH4)). All or
most such gases are explosive and/or poisonous or anaesthetic. Forget them.

  Likely the diver and his blowtorch could run off the same cylinders!
