To avoid risk of having a convulsion and drowning due to oxygen toxicity,
always stay well within your dive computer's oxygen exposure limits. Stay
shallower than the maximum depth of the blend you're using. You should not
exceed an oxygen partial pressure of 1.4 ata/bar.
Just as you would any emergency involving an unresponsive diver
underwater. (Go over the procedure)
Hold the regulator in the mouth if it is there
This is your maximum depth. Stay above it to keep CNS toxicity risk low.
Although many computers warn if you exceed it, use this feature as a
secondary alert. Know your depth at all times and stay above the maximum
, Although you can experience log term (pulmonary) oxygen toxicity by
exceeding oxygen exposure limits, the primary hazard is the immediate one of
downing due to a CNS convulsion underwater

Set the maximum oxygen partial pressure for 1.4 (1.6 is the
contingency limit) and set the computer for the blend you're using.
With most models, the deepest depth displayed when you scroll the
no stop limits is the maximum depth. You should watch the depth
as your primary means of staying shallower than this depth - use
the
computer's warning as a secondary alert. Stay well within the
computer's oxygen exposure limits. It's generally recommended
that you allow at least an hour between nitrox dives to help stay
well within oxygen exposure limits. Always follow the
manufacturer's
guidelines regarding settings and displays.

Generally, for all equipment except your cylinder you can use
regular scuba equipment with enriched air with up to 40% oxygen.
However, local laws, standards or practices may require special
fittings or cleanings; follow these if they apply. In any case, during
servicing, oxygen compatible lubricants, as well as other materials,
are generally recommended.
