i
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 thousands of 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.
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.

ii
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, then 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.

iii
Treatment to Give When the Patient Has a Pulse
Beating but Has Ceased to Breathe
* Performing mouth-to-mouth artificial respiration (see Figure 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]
(3) Blowing air into the patient's lungs.
Blow air into the patient's lungs until
chest is seen to rise. The first 10
breaths must be blown as fast as
possible.

Flow of Cardiopulmonary Resuscitation (CPR)
Using the AED (Automated External Defibrillator)
A person is collapsing.
- Secure the safety of the surrounding area.
- Prevent secondary disasters.
Check for response.
- Call while tapping the shoulder.
Ask for help.
- Make an emergency call.
- Ask to bring an AED.
Open the airway.
- Check for breathing.
Give 2 rescue breaths; omittable. Note(1)
Give CPR.
- 30 chest compressions.
- Give 2 rescue breaths; omittable. Note(1)
Arrival of an AED.
- Turn on the power.
- Use the AED by following its voice prompts.
Fitting of the electrode pads, etc.
Automatic electrocardiogram analysis.
- Do not touch the injured or ill person.
Delivery of electric shock.
Resume CPR from chest
compressions by following the
voice prompts of the AED.
The AED automatically
analyzes the heart
rhythm every 2 minutes.
When the injured or ill person
has been handed over to the
emergency services or 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.
Listen to the appeal of the
injured or ill person and give
the necessary first-aid
treatment.
Recovery position.
- Lay the injured or ill person
on his/her side and wait for
the arrival of the emergency
services.
Note(1) Omission of rescue breathing:
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
preparing the mouthpiece for rescue
breathing takes too long, omit rescue
breathing and proceed to the next step.

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 call and
bring an AED.
- Somebody has collapsed. Please help.
- Please call an ambulance.
- Please bring an ambulance AED.
- If there is nobody to help, call an ambulance yourself.
5. Open the airway
a) Touch the forehead with one hand.
b) Lift the chin with the two fingers of the middle finger and forefinger of
the other hand.
c) 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.

vi
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.

vii
8. Cardiopulmonary resuscitation (CPR) (combination of chest
compressions and rescue breaths)
a) 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.
b) 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.
c) Combination of 30 chest compressions and 2 rescue breaths
- After performing 30 chest compressions, give 2 rescue breaths.
If rescue breathing is omitted, perform only chest compressions.
- Continuously perform the combination of 30 chest compressions
and 2 rescue breaths without interruption.
- 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.
