Cautions for High Voltage
High voltages, ranging from several hundreds to tens of thousands of volts, are used in
electronic apparatus, such as radio and radar instruments. These voltages are totally
harmless in most operations. However, touching a component inside the unit is very
dangerous. (Any person other than authorized service engineers should not maintain,
inspect, or adjust the unit.)
High voltages on the order of tens of thousand volts are most likely to cause instant
deaths from electrical shocks. At times, even voltages on the order of several hundred
volts could lead to electrocution. To defend against electrical shock hazards, don't put
your hand into the inside of apparatus. When you put in a hand unavoidably in case of
urgent, it is strongly suggested to turn off the power switch and allow the capacitors, etc.
to discharge with a wire having its one end positively grounded to remove residual
charges. Before you put your hand into the inside of apparatus, make sure that internal
parts are no longer charged. Extra protection is ensured by wearing dry cotton gloves at
this time. Another important precaution to observe is to keep one hand in your pocket at
a time, instead of using both hands at the same time.
It is also important to select a secure footing to work on, as the secondary effects of
electrical shock hazards can be more serious. In the event of electrical shocks, disinfect
the burnt site completely and obtain medical care immediately.

ii 7ZPNA4619A
Precautions for Rescue of Victim
of Electric Shock
When a victim of electric shock is found, turn off the power source and ground the circuit
immediately. If this is impossible, move the victim away from the unit as quick as possible
without touching him or her with bare hands. He or she can safely be moved if an
insulating material such as dry wood plate or cloth is used.
Breathing may stop if current flows through the respiration center of brain due to electric
shock. If the electric shock is not large, breathing can be restored by artificial respiration.
A victim of electric shock looks pale and his or her pulse may become very weak or stop,
resulting in unconsciousness and rigidity at worst. It is necessary to perform first aid
immediately.

7ZPNA4619A iii
Method of First-Aid Treatment
Precautions for First-Aid
Treatments
Whenever a person is struck by an electrical shock, give the patient artificial respiration
immediately on the spot, unless it is absolutely necessary to move the patient for safety's
sake. Once started, artificial respiration should be continued rhythmically.
(1) Refrain from touching the patient carelessly as a result of the accident; the first-aider
could suffer from electrical shocks by himself or herself.
(2) Turn off the power calmly and certainly, and move the patient apart from the cable
gently.
(3) Call or send for a physician or ambulance immediately, or ask someone to call
doctor.
(4) Lay the patient on the back, loosening the necktie, clothes, belts and so on.
(5) (a) Feel the patient's pulse.
(b) Check the heartbeat by bringing your ear close to the patient's heart.
(c) Check for respiration by bringing your face or the back of your hand to the
patient's face.
(d) Check the size of patient's pupils.
(6) Opening the patient's mouth, remove artificial teeth, cigarettes, chewing gum, etc. if
any. With the patient's mouth open, stretch the tongue and insert a towel or the like
into the mouth to prevent the tongue from being withdrawn into the throat. (If the
patient clenches the teeth so tight that the mouth won't open, use a screwdriver or
the like to force the mouth open and then insert a towel or the like into the mouth.)
(7) Wipe off the mouth to prevent foaming mucus and saliva from accumulating.

iv 7ZPNA4619A
Treatment to Give When the Patient Has
a Pulse Beating but Has Ceased to
Breathe
∗Performing mouth-to-mouth artificial respiration - Fig. 1
(1) Bend the patient's face backward until it is directed to look back. (A pillow may be
placed under the neck.)
(2) Pull up the lower jaw to open up the airway. (To spread the airway)
(3) Pinching the patient's nose, breathe deeply and blow your breath into the
patient's mouth strongly, with care to close it completely. Then, move your mouth
away and take a deep breath, and blow into his or her mouth. Repeat blowing at
10 to 15 times a minute (always with the patient's nostrils closed).
(4) Continue artificial respiration until natural respiration is restored.
(5) If the patient's mouth won't open easily, insert a pipe, such as one made of
rubber or vinyl, into either nostril. Then, take a deep breath and blow into the
nostril through the pipe, with the other nostril and the mouth completely closed.
(6) The patient may stand up abruptly upon recovering consciousness. Keep the
patient lying calmly, giving him or her coffee, tea or any other hot drink (but not
alcoholic drink) to keep him or her warm.
Mouth-to-mouth artificial respiration with the patient's head lifted
[1]
(1) Lift the back part of the patient's
head. Support the forehead with
one of your hand and the neck
with the other hand.→[1].
Many patients will have their
airways opened by lifting their
head in this way to ease
mouth-to-mouth artificial
respiration.
[2]
(2) Closing the patient's mouth with
your mouth, press your cheek
against the patient's nose→[2].
Alternatively, hold the patient's
nose with your finger to prevent air
leak
→[3].

(3) Blowing air into the patient's
lungs. Blow air into the patient's
lungs until chest is seen to rise.
T
he first 10 breaths must be blown
as fast as possible.
Fig. 1 Mouth-to-mouth artificial respiration
 Treatment to Give When the Patient Has No
Pulse Beating and Has Ceased to Breathe
∗Performing cardiac massage - Fig. 2
If the patient has no pulse beating, with the pupils open and no heartbeat being heard,
the patient has a cardiac arrest and requires immediate artificial respiration. Continue
this until a medical specialist arrives, and follow his or her directions after that.
(1) Putting one hand on about the lower one third of the patient's ribs and the other hand
over the back of the first, with your elbow fully stretched (with bended elbow, you
can’t press to the extent the patient’s ribs are depressed), apply your body weight to
the hands to press the patient's body until it is depressed about 2 cm (Repeat this
about 50 times a minute). (Cardiac massage)
(2) If only one first-aider is available, perform a cardiac massage about 15 times and
then give mouth-to-mouth artificial respiration 2 times. Repeat this sequence.
If two first-aiders are available, while one person performs a cardiac massage 15
times, the other should give mouth-to-mouth artificial respiration 2 times. Repeat this
sequence. (Combined cardiac massage and mouth-to-mouth artificial respiration
method)
(3) Check the patient's pupils and feel the pulse from time to time. When the pupils are
restored to normal and the pulse begins to beat regularly, stop treating and keep the
patient calm while giving him or her coffee, tea or any other hot drink to keep him or
her warm while watching him or her carefully.

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.
• Somebody has collapsed. Please help.
• Please call 119.
• Please bring an AED.
• 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.
Are you OK?
Please call 119.
Please bring an AED.

7ZPNA4619A ix
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.
• Look to see if the chest and abdomen are rising and falling.
• Listen for breathing.
• 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.
• 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.
Roll gently in the opposite
direction every 30 minutes.

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.
30 times
Compress
with these
parts (the
heels of
both
hands).
2 times

7ZPNA4619A xi
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
female).
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) Do not put child pads on adults (older than 8 years).
Turn on the power.

xii 7ZPNA4619A
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.
Press the shock button.
