carbon monoxide

I have heard that you can loose oxygen while you are diving if you do
not open the valve all the way or there is not the right mixture of
carbon monoxide. How much carbon monoxide can be in your tank for you
to still be all right, at any depth?

You gotta be kidding, right?

Sort of. Can you not survive with any?

obviously, for you, 10% CO

outrage to discriminate against any such man because of creed, or

in every facet an American, and nothing but an American.
“There can be no divided allegiance here. Any man who says he is an
American, but something else also, isn’t an American at all.

Partially opening the valve is, um, not the right procedure. As for CO,
according to http://www.scuba-doc.com/carbonmon.html :

"The maximal allowable level is 20 ppm (0.002%)."

In late August, 1946, J. Cousteau and his merry band went cave diving in
the Fountain of Vaucluse in Avignon. (Ottonelli first dove the cave in
1878, so the route was known.) Jean Pinard made the first descent solo,
putting a weighted line down to 90 feet. Cousteau and Dumas, connected
with a buddy line, went down next.

The details of what happened next vary somewhat between reports.
Somewhere around 150 feet the depth gauge, carried by Dumas, imploded.
At about the same time, both divers became light headed and disoriented.
Dumas lost his mouthpiece but managed to recover it. Cousteau, confused
and frightened witless, frantically tried to scramble up the down line,
impeded by the buddy line attached to the negatively buoyant,
semi-conscious Dumas. Meanwhile, the surface tender, thinking the
jerking line was a signal for more rope, payed out line instead of
pulling up. Finally, the tender sensed that not all was well and began
to retrieve the line. Disaster was averted and two more divers, Tailliez
and Morandiere, did the same dive with similar results.

It was later determined that exhaust fumes had been drawn into the
compressor and the high partial pressure of the carbon monoxide was
poisoning the divers.

Are you for real or just a troll - Carbon Monoxide????? You better head
back to class and get your money back

don't dive to deep - it will be your last - if you get off the boat

If you're serious, that's like asking how much poison can I drink and still
be okay. Carbon monoxide would be injected into a tank by faulty filling
equipment. They do make testers for this, not cheap, but I've heard that 2
divers die each year from carbon monoxide.

It should. You did a lot of research and came up with a load of stuff
that enthusiastic divers will find informative and entertaining if not
downright fascinating. Ya done good. Get it out there.
