WARNING
Never use any aero-
sol propelled sprays
near the face port
of the any Kirby
Morgan helmet or
band mask. The
propellant used in
these aerosols can
invisibly damage the
polycarbonate face
port and cause it to
shatter upon impact
from any strong
blow. If the face port
fails underwater the
helmet will flood
and drowning may
result.
3.8.5 Donning The Kirby Morgan Helmet
All donning procedures must be done by the diver
until he is thoroughly familiar with the helmet. How
-
ever, 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. See 3.4.2 for
trim and fit procedures if needed.
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.
Neck Dam Ring Assembly Note: All screw heads
seen on this assembly should face down (away) from
the helmet when donning this assembly. This will
always ensure the pull strap is properly directed.
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 pointing
towards the divers chin. Lift the neck ring assembly
over your head, grasping the front and rear of the
neck ring assembly. Begin to pull the neck dam down
over your head. The neck dam should slide over the
divers head without excessive strain. 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 uncomfortable
and waste breathing gas.
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.
With the diver holding the helmet, the tender should
now connect the quick disconnect fittings for the bail
-
out supply. Make sure the locking device is properly
aligned. 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.
With the helmet face down, pull the sealed pull pins
and open the locking collar/neck pad assembly fully.
Be sure the head cushion is attached to the bottom
of the helmet. Pull the nose block device knob out
all the way.
Loosen the chin strap all the way. The helmet is worn
most comfortably when the chin cushion against the
diver’s chin with the chin strap outside of the chin
cushion.
With the locking collar/neck pad assembly fully open,
lift the helmet and place it over your head. Lower
the helmet onto the back of your head first, then pivot
it forward until your face is in position against the
oral nasal mask.

WARNING
The tender must always be present
to assist the diver while dressing and
whenever 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.
