3.9 Removing the Helmet
To remove the Kirby Morgan helmet, start by pulling
out (forward) on each sealed pull pin and turning so
each remains in the open position. Tilt your head,
and the helmet, forward and swing the locking collar
assembly back behind your shoulders.
Tilt your head upright again and push the swinging
tongue catch forward with one hand and hold it in this
position. Grasp the pull strap and pull down on it, to-
wards your back. This will break the seal between the
neck dam/neck ring and the helmet neck ring on the
base of the helmet. Once the seal is broken the neck
ring assembly will come loose from the helmet.
Pull the nose block device knob away from your face,
loosen the chin strap, and lift the helmet off of your
head. A good tender will be prepared to help the diver
with the removal of the helmet as required.
Grab the neck ring at the front and use your fingers
to gather the neck dam away from your neck in the
front. Lift the neck dam over your head.
With the locking collar open, you can use the pull
strap to break the seal between the neck dam ring
and the helmet ring.
