Kirby Morgan 77
Rapid ascent is dangerous. It can lead to
air embolism or decompression sickness.
Air/gas embolism can cause immediate
loss of consciousness and/or death.
Even on a no decompression dive, a
rapid ascent may cause decompression
sickness. A diver must only make a rapid
ascent when he is in immediate danger of
death by drowning or asphyxiation.
DANGER
Ditching the helmet underwater must be
avoided. If the diver ditches the helmet
underwater he will not be able to see.
In many instances, even if the air sup-
ply is interrupted, topside will be able to
get it back on line quickly. Do not ditch
the helmet underwater unless you are
completely out of breathing gas and it is
impossible to return to the surface due
to entanglement of your equipment or
similar circumstances.
DANGER
Never remove the diving helmet while
you are in the stage. If you fall out of the
stage with the helmet off but still attached
to your harness it may be very difficult to
swim. Drowning may result.
WARNING
3.11.4 Demand Regulator Free Flow
If the demand regulator free flows, turn the adjust-
ment knob in (clockwise) until it stops. If the free
flow cannot be stopped, the dive should be aborted.
Even if there is no serious problem to the diver, the
dive should be aborted and the problem with the
regulator corrected.
Sometimes it may be necessary to tilt your head so
the regulator is face up to help stop the regulator in a
free-flow situation.
