Kirby Morgan 77
The tender must always be present to
assist the diver while dressing and when-
ever the diver has his helmet on his head
while he is out of the water. It is difficult
for the diver to walk while he is dressed
in and he can stumble and fall, resulting
in serious personal injury.
WARNING
The tender must be available to assist the diver while he is dressing into his helmet.
3.8.5 Donning The Kirby Morgan Helmet
All donning procedures must be done by the diver
until he is thoroughly at home with the helmet. This
will train for familiarity. However, the tender must
be present to assist the diver and check to ensure that
the diver has properly donned his equipment. It is
impossible for the diver to see whether he is properly
dressed in once the helmet is on his head.
To dress in, the neck dam ring assembly must first be
pulled down over the diver’s head.
Be sure to loosen the chin strap inside the helmet prior
to donning the neck dam. To loosen the strap, place
your thumb on top of the rounded end of the plastic
buckle and pull down, away from the helmet.
To don the neck dam, hold the neck dam/ring assem-
bly vertically, in front of your chest, so that the large
end of the assembly where the pull strap is mounted
is on top. The pull strap should both be facing your
chest. Lift the neck ring assembly over your head,
grasping the front and rear of the neck ring assembly.
Pull the neck dam down over your head. The neck
dam should be as low as possible on your neck.
The neck dam is always turned up against the
diver’s neck. This is very important!
With the neck dam turned down, the helmet will vent
air from the neck dam causing the regulator to free
flow. This will make the helmet very uncomfort-
able.
The neck dam ring assembly must be oriented so the
“tongue” on the front of the neck dam ring assembly
is pointed to the front of your body, in front of and
below your chin. You should be able to look down
and see the tongue sticking out from underneath the
neck dam ring assembly when you are wearing the
assembly and it is oriented properly.
With the diver holding the helmet, the tender should
now connect the quick disconnect fittings for the
bailout supply. Open the regulator adjustment knob
and the defogger control knob for a steady flow from
both just prior to the diver dressing into the helmet.
