A. General Information
(Before you begin)
7ZPNA2401

1. Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic
equipment such radio and radar devices. You do not face any danger during normal operation, but
sufficient cares are required for maintenance, inspection and adjustment of their internal components.
(Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by
maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from
electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock.
When you touch any parts inside these devices, before doing so, you should make it a rule to turn off
the power switch to prevent such an accident caused by electric shock, and discharge capacitors with a
wire surely earthed on an end and make sure that internal parts are no longer charged. Furthermore,
when doing so, wearing dry cotton gloves protect you from such danger. It is also necessary to put one
of your hands in the pocket and not to use both your hands at the same time.
It is also important to select a stable foothold always to prevent secondary accidents once you were
electrically shocked. If you are injured from electric shock, you disinfect the burn sufficiently and give
medical treatment to it promptly.

2. What to do for Electric Shock
When finding a victim of electric shock, you should call a person(s) near there, and turn off the
power source and earth the circuit immediately. If it is impossible for you to turn off the circuit
immediately, you should move the victim away promptly using insulators such as dry wood plate and
cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the respiration center in
the brain. If the shock is not so strong, artificial respiration may recover breathing. When shocked by
electricity, the victim will come to look very bad with weak pulse or without beating, resulting in
unconsciousness and rigidity.
First-aid treatments
As far as the victim of electric shock is not in dangerous condition, you should not move the victim
and practice artificial respiration on the victim immediately. Once respiration is started, it should be
continued rhythmically.
(1) Tell the accident to persons near there loudly and ask them to gather
(2) Do not touch the victim confusedly as result of the accident, or rescuer may also get an electric
shock.
(3) Turn off the power source calmly and move the victim away quietly from the electric line.
(make sure whether places near there is safe.)
(4) Try to contact persons or offices concerted (Clinic, hospital, doctor, emergency call, etc.)
(5) Lay the victim on his back and loosen his necktie, clothes, belt, etc.
(6) - a Feel the victim’s pulse.
- b Fell the victim’s heartbeat bringing your ear close to his heart.
- c Examine his breathing bringing the back of your hand or your face close to his face.
- d Check the size of the pupils of his eyes.
(7) Open the victim’s mouth and take out artificial teeth, cigarette or chewing gum if any. Keep his
mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent the tongue
from suffocating. (If it is hard to open his mouth due to set teeth, open it with a screwdriver and
insert a towel in this mouth.)
(8) Then, clean the victim’s mouth so that foaming mucus does not accumulate inside the mouth.

3. When pulse is beating but breathing has stopped
Give a ( Mouth-to-mouth respiration ) Fig. 1
(1) Tilt the victim’s head back as far as this face looks back. (A pillow may be inserted his neck.)
(2) Push the victim’s jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victim’s nostrils and take a deep breath, cover the victim’s mouth completely with yours
and blow into the victim’s mouth strongly. Take a deep breath again and blow into the victim’s
mouth. Continue this 10 to 15 times a minute (blocking his nostrils).
(4) Practicing artificial respiration, carefully watch whether the victim has recovered his natural
breathing, soon after the victim recovered, stop respiration.
(5) If it is difficult to open the victim’s mouth, insert a rubber or vinyl tube into one of the victim’s
nostrils and take a deep breath and blow into it, blocking the victim’s other nostril and mouth
completely.
(6) When the victim recovers consciousness, the victim may try to stand up suddenly, but let the victim
lie calmly and serve the victim with a cup of hot coffee or tea and keep the victim warm and quiet.
(Never give him alcoholic drinks.)
Method of mouth-to-mouth respiration by raising head
(1) Raise the victim’s head. Support his
forehead with one of your hand and his neck
with the other hand. →①
When you tilt his head backward, the victim,
in most cases, opens his mouth to the air.
This makes mouth-to-mouth respiration
easy.
(2) Cover his mouth as widely as possible
with yours and press your cheek
against his nose →②
Or, pinch his nostrils with your fingers to
prevent air from leaking. →③
(3) Blow into lung.
Blowing into mouth until his breast swells.
Blow into his mouth as quickly as possible 10
times at first.

4. When both pulse and breathing have stopped
Give a (Cardiac massage). Fig. 2
When pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest is
supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone and
compress his breast with your elbows applying your weight on his breast so that it is dented about
2 cm (Repeat compressing his beast 50 times / minute or so).
(Cardiac massage)
(2) In case of one rescuer,
Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat his
combination.
(3) In case of two rescuers,
One person repeats cardiac massages 15 times while the other person blow into his mouth once,
and they shall repeat this combination. (Perform the cardiac massage and mouth-to-mouth
respiration)
(4) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop he
artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and calm while
watching him carefully. (Never give him alcoholic drinks.)

6. Procedure for cardiopulmonary resuscitation (CPR) using
the AED (Automated External Defibrillator)
1. Check the scene for safety to prevent secondary disasters
a) Do not touch the injured or ill person in panic when an accident has
occurred. (Doing so may cause electric shock to the first-aiders.)
b) Do not panic and be sure to turn off the power. Then, gently move the
injured or ill person to a safe place away from the electrical circuit.
2. Check for responsiveness
a) Tap the shoulder of the injured or ill and shout in the ear saying, "Are
you OK?"
b) It the person opens his/her eyes or there is some response or gesture,
determine it as "responding." But, if there is no response or gesture,
determine it as "not responding."
3. If responding
a) Give first-aid treatment.
4. If not responding
a) Ask for help loudly. Ask somebody to make an emergency 119 call
and bring an AED.
1) Somebody has collapsed. Please help.
2) Please call 119.
3) Please bring an AED.
4) If there is nobody to help, call 119 yourself.
5. Open the airway
a) Touch the forehead with one hand. Lift the chin with the two fingers of
the middle finger and forefinger of the other hand and push down on
the forehead as you lift the jaw to bring the chin forward to open the
airway. If neck injury is suspected, open the airway by lifting the lower
jaw.

6. Check for breathing
a) After opening the airway, check quickly for breathing for no more than
10 seconds. Put your cheek down by the mouth and nose area of the
injured or ill person, look at his/her chest and abdomen, and check the
following three points.
1) Look to see if the chest and abdomen are rising and falling.
2) Listen for breathing.
3) Feel for breath against your cheek.
b) If the injured or ill person is breathing, place him/her in the recovery
position and wait for the arrival of the emergency services.
1) Position the injured or ill person on his/her side, maintain a clear
and open airway by pushing the head backward while positioning their
mouth downward. To maintain proper blood circulation, roll him/her
gently to position them in the recovery position in the opposite
direction every 30 minutes.
7. Give 2 rescue breaths (omittable)
a) If opening the airway does not cause the injured or ill person to begin
to breathe normally, give rescue breaths.
b) If there is a fear of infection because the injured or ill person has an
intraoral injury, you are hesitant about giving mouth-to-mouth
resuscitation, or getting and preparing the mouthpiece for rescue
breathing takes too long, omit rescue breathing and perform chest
compressions.
c) When performing rescue breathing, it is recommended to use a
mouthpiece for rescue breathing and other protective devices to
prevent infections.
d) While maintaining an open airway, pinch the person's nose shut with
your thumb and forefinger of the hand used to push down the
forehead.
e) Open your mouth widely to completely cover the mouth of the injured
or ill person so that no air will escape. Give rescue breathing twice in
about 1 second and check if the chest rises.

8. Cardiopulmonary resuscitation (CPR) (combination of chest
compressions and rescue breaths)
a) Chest compressions
1) Position of chest compressions
- Position the heel of one hand in the center of the chest,
approximately between the nipples, and place your other hand on top
of the one that is in position.
2) Perform chest compressions
- Perform uninterrupted chest compressions of 30 at the rate of about
100 times per minute. While locking your elbows positioning yourself
vertically above your hands.
- With each compression, depress the chest wall to a depth of
approximately 4 to 5 cm.
b) Combination of 30 chest compressions and 2 rescue breaths
1) After performing 30 chest compressions, give 2 rescue breaths. If
rescue breathing is omitted, perform only chest compressions.
2) Continuously perform the combination of 30 chest compressions
and 2 rescue breaths without interruption.
3) If there are two or more first-aiders, alternate with each other
approximately every two minutes (five cycles of compressions and
ventilations at a ratio of 30:2) without interruption.

9. When to stop cardiopulmonary resuscitation (CPR)
a) When the injured or ill person has been handed over to the
emergency services
b) When the injured or ill person has started moaning or breathing
normally, lay him/her on his/her side in a recovery position and wait for
the arrival of emergency services.
10. Arrival and preparation of an AED
a) Place the AED at an easy-to-use position. If there are multiple
first-aiders, continue CPR until the AED becomes ready.
b) Turn on the power to the AED unit. Depending on the model of the
AED, you may have to push the power on button, or the AED
automatically turns on when you open the cover.
c) Follow the voice prompts of the AED.
11. Attach the electrode pads to the injured or ill person's bare
chest
a) Remove all clothing from the chest, abdomen, and arms (male or
emale).
b) Open the package of electrode pads, peel the pads off and securely
place them on the chest of the injured or ill person, with the adhesive
side facing the chest. If the pads are not securely attached to the
chest, the AED may not function. Paste the pads exactly at the
positions indicated on the pads, if the chest is wet with water, wipe dry
with a dry towel and the like, and then paste the pads. If there is a
pacemaker or implantable cardioverter defibrillator (ICD), paste the
pads at least 3cm away from them. If a medical patch or plaster is
present, peel it off and then paste the pads. If the injured or ill person's
chest hair is thick, paste the pads on the chest hair once, peel them off
to remove the chest hair, and then paste new pads.
c) Some AED models require to connect a connector by following voice
prompts.
d) The electrode pads for small children should not be used for children
over the age of 8 and for adults.

12. Electrocardiogram analysis
a) The AED automatically analyzes electrocardiograms. Follow the voice
prompts of the AED and ensure that nobody is touching the injured or
ill person while you are operating the AED.
b) On some AED models, you may need to push a button to analyze the
heart rhythm.
13. Electric shock (defibrillation)
a) If the AED determines that electric shock is needed, the voice prompt
saying, "Shock is needed" is issued and charging starts automatically.
b) When charging is completed, the voice prompt saying, "Push the
shock button" is issued and the shock button flashes.
c) The first-aider must get away from the injured or ill person, make sure
that no one is touching him/her, and then press the shock button.
d) When electric shock is delivered, the body of the injured or ill person
may jerk.
14. Resume cardiopulmonary resuscitation (CPR).
Resume CPR consisting of 30 chest compressions and 2 rescue breaths
by following the voice
Prompts of the AED.
15. Automatic electrocardiogram analysis
a) When 2 minutes have elapsed since you resumed cardiopulmonary
resuscitation (CPR), the AED automatically analyzes the
electrocardiogram.
b) If you suspended CPR by following voice prompts and AED voice
prompt informs you that shock is needed, give electric shock again by
following the voice prompts. If AED voice prompt informs you that no
shock is needed, immediately resume CPR.
16. When to stop CPR (Keep the electrode pads on.)
a) When the injured or ill person has been handed over to the
emergency services
b) When the injured or ill person has started moaning or breathing
normally, lay him/her on his/her side in a recovery position and wait for
the arrival of emergency services.

8. Things taken into account at work
There are many things to know at work at radio stations. The followings below are especially
important.
8-1 Observance of Radio regulations and rules concerned
You should not only observe the regulations and rules above, but you should also observe rules of
each port or each ship. Especially onboard ships which carry dangerous cargos, when fire work is
carried out and radio waves are transmitted or work is done on open deck such as compass deck,
permission should be obtained before work is started.
8-2 No permission to transmit radio waves by unqualified persons
When transmissions of radio waves are needed during repairing or maintenance, work should be
carried out under observation of ship’s qualified persons.
8-3 Dummy antenna may be used during adjustment of transmitters if possible.
8-4 Whatever equipment may be operated, distress signals should not be
transmitted even through dummy antenna. ( Note 1 )
If distress signals were transmitted by accident, nearby Competent Authority’s Radio station or
Coast Radio Stations should be immediately informed of what happed.
Contents to be informed
1) Ship’s name
2) Call sign
3) the time of transmission and the time of ceasing transmitting
4) the reason why erroneously transmitted
Note1 : When maintenance or test of EPIRBs is carried out onboard ships, and radio wave
shielded confined room such as engine control room etc. should be used not to transmit radio
wave outside the ship (If an antenna is there, it should be removed temporally.) and stop
transmission soon after test is over.
