3.12 Post Dive Procedures

3.12.1 Removing the Equipment

After t he diver is well clear of the water he may

remove the helmet. If the diver is working out of a

stage he must not remove the helmet until the stage

is on deck.

3.12.2 Removing the Helmet

Remove the helmet by pull ing the sealed pull pins

out (forward) and turning them until they are locked

open in the extended position. Tilt your head and the

helmet forward and swing the locking collar back

behind your shoulders. You will need to pull down

on the pull strap to break the seal between the neck

dam ring and the helmet ring a nd to disengage the

neck ring from the swing tongue catch.

Once the neck ring is disengaged from helmet ring,

you can loosen the chin strap and then 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.

The emergency gas supply hose may be disconnected

while the diver leaves the helmet on or while he holds

the hat after removal. The quick disconnect makes

this procedure very easy.

The tender should then unfasten the umbilical from

the harness and ta ke the helmet from the diver and

set it aside. (Closing the locking collar/neck pad as-

sembly onto the helmet before setting the hat down

on a rough deck will help protect the helmet neck

ring from damage). The harness a nd bailout bottle

is then removed.

3.12.3 Storage of the Helmet

The helmet should be maintained per the daily main-

tenance section in Chapter 6.

If the helmet is not going to be used for a period of

time, the head cushion, should be removed. The head

cush ion s hou ld b e dr ied and rep lace d i n th e ha t bef ore

storage. The regulator adjustment knob should be

unscrewed all the way out (counterclockwise) until

the next dive. Be sure to check the communications

components and allow them to fully dry.

When the helmet is completely dry, or t he diver is

ready to leave the job, the helmet should be stored in

the carrying bag to protect it.

If the head cushion becomes wet it may be dried out

WARNING

head cushion foam in a drier. Use of a

higher setting could cause the foam to

melt or start a ﬁre.

by removing it from the helmet, squeezing excess

water out, and letting the head cushion hang dry or

putting it in a clothes drier on air dry only.

The helmet should be rinsed with clean f resh water

following each use, then thoroughly cleaned.
