damage control circuit and is common to the
damage control station and all repair parties. It
connects DCC with repair parties II, III, and V.
The 3, 4, 5, 6, and even 7JZ circuits are individual
repair party circuits connecting each repair party
station with its auxiliary station and patrol area.
The following are some of the other typical

The 4MC circuit is the damage control intercom
system. It provides two-way communications
between DCC and the repair stations. It also
provides communications from repair lockers to
their respective unit patrol areas by means of
remote units powered through the call switches
on the repair lockers intercom unit.
Ships service telephones are available for use
where they are installed near repair stations. Do
not place too much reliance on them, as they may
go out of commission early in the action.
The ships general announcing system is a
means of communications, but so many stations
are affected that it should only be used when all
other methods fail.
When all other means of communications
have failed, you can use messengers. Train
messengers to relay oral orders information
without error, even though written messages are
more reliable. See Military Requirements for Petty
Officer Third Class, NAVEDTRA 12044, for a
discussion on messengers.

PERSONNEL CASUALTY CONTROL
First aid is the emergency treatment of the sick
or injured before regular medical or surgical
attention can be obtained. In this section we will
only give you basic rules. For more detailed
information on treatment, refer to Basic Military
Requirements, NAVEDTRA 12043. First aid does
not take the place of proper medical attention.
It only provides assistance to the injured until
proper medical care can be obtained. The purpose
of first aid is to
1. save life,
2. prevent further injury, and
3. preserve resistance and vitality.
When providing first aid to injured person-
nel, be sure to follow these rules:
1. Keep the patient lying down, head level,
until the injuries have been determined.
2. Examine the patient for cessation of
breathing, hemorrhage, and evidence of shock.
These conditions take precedence in this order
over everything else and demand immediate
3. Remove clothing to determine the extent
of the injury. Rip or cut the clothing along the
seams, Removing clothing in the normal manner
may compound the injury, especially in fractures.
Do not remove too much clothing; exposure to
cold may bring on the condition of shock.
4. Remain calm. Act quickly but efficiently.
Determine which of the patients injuries needs
attention first, and then determine the proposed
course of action.
5. Keep the patient comfortable. This can be
done while the patients injuries are being treated.
A blanket may do the patient as much good as
the dressing applied to his wounds. Keep the
injured person warm enough to maintain normal
6. Do not allow the patient to see the injury.
Assure the patient that the injuries are understood
and that good care will be given. Such things are
important in keeping a patient calm and preventing
