Rapid ascent is dangerous. It can lead
to air embolism or decompression sick-
ness. Air/gas embolism can cause im-
mediate loss of consciousness and/or
death. Even on a no decompression dive,
a rapid ascent may cause decompres-
sion sickness. A diver must only make a
rapid ascent when they are in immediate
danger of death by drowning or asphyxi-
ation.
DANGER
Ditching the helmet underwater must be
avoided. If the diver ditches the helmet
underwater they 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
umbilical is clear and return to the diving station us-
ing the emergency breathing supply. Avoid making
a rapid ascent if at all possible.
Once at the surface, or inside the bell, the diver may
remove the helmet if needed. Never ditch the helmet
underwater unless conditions absolutely require that.
3.10.4 Demand Regulator Free Flow
If the demand regulator free flows, adjust the 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.
3.11 Post Dive Procedures
3.11.1 Removing the Equipment
After the diver is well clear of the water they may
remove the helmet. If the diver is working out of a
stage they must not remove the helmet until the stage
is on deck.
3.11.2 Removing the Helmet
On the SuperLite
®
-17 A/B, the tender must first
remove the safety pin before you can remove the
helmet. Slide the pin out and away from the latch
catch. Release the yoke safety strap.
The tender should assist the diver by pulling out on
the pull pin knob on the latch catch assembly. This
will allow the let the yoke to fall away. Next grab the
handle on the neck clamp assembly and pull outwards
away from the helmet, until the handle is in front of
the diver’s face. This action will break the seal of
the neck dam around the base of the helmet and the
neck dam and clamp will fall away from the bottom
front of the helmet.
While having the diver tilt their head back, reach
behind the back of the helmet and lift the rear hinge
tab off the alignment sleeve in the back of the helmet.
When you’re wearing the helmet, once the neck
clamp is open, you must reach underneath the front
of the helmet and loosen the chin strap that holds the
helmet in position. Then, lift the helmet over your
head using both hands, one on either side of the hel-
met to support its weight.
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.
