RESCUE
1. Free victim from contact with live conductor quickly.
Avoid contact with neither live conductor nor victim’s body.
2. Shut off high voltage at once and ground the circuit. If high voltage cannot be turned off
quickly, ground the circuit to discharge, or cut high voltage line by an ax with dry wooden
handle. Be careful of electric flash.
3. If circuit cannot be broken or grounded, use a dry board, dry clothing, or other
nonconductor to free victim.
4. Call an ambulance immediately.
SYMPTOMS
NEVER TAKE ELECTRICALLY SHOCKED CONDITION AS DEATH.
Symptoms of electric shock may include unconsciousness, failure to breathe, absence of
pulse, pallor, and stiffness, as well as severe burns.
Whenever victim is not breathing properly, give artificial respiration(see next page).
TREATMENT
1. Start artificial respiration at scene of accident. Only in case victim’s or
operator’s life is endangered, remove victim to safe location nearby.
2. After starting artificial respiration, continue without loss of rhythm until victim start
breathing without help, or being passed to medical aid.
3. When operator change while giving artificial respiration, do so without losing the
rhythm of respiration.
4. After giving first aid, try to get a diagnosis by a doctor as soon as possible because
shock can cause internal burn, which can be lethal if left untreated.
AFTER VICTIM REVIVES
Be prepared to resume artificial respiration, as he may stop breathing again.
Keep victim warm and lying down until he or she has been conscious for at least thirty minutes.
First-aid procedures to be implemented in case of electrical shock

v
1. PLACE VICTIM
Place victim in face-upward position horizontally.
2. CLEAR THROAT
Turn head to one side quickly wipe out any fluid, mucus, or
foreign body from mouth and throat with fingers.
3. OPEN AIR PASSAGE
Tilt head back and extend neck to open air passage.
4. LIFT JAW FORWARD
Put thumb in victim’s mouth and grasp jaw firmly. Lift jaw
forward to pull tongue out of air passage. Do not hold or depress
tongue.
5. PINCH NOSTRILS CLOSED
With other hand pinch nostrils closed to prevent air leak.
6. BLOW AIR IN
Take a deep breath, seal victim’s open mouth and exhale firmly
into victim’s mouth until chest is seen to lift.
Make sure to open mouth widely to avoid air leakage.
7.REMOVE MOUTH AND CHECK
Check the sound of breathing out air and see normal breathing when
releasing mouth. If no sound, repeat from OPEN AIR PASSAGE. Continue at
a rate of 12 to 20 times per minute.
Quantity of air have to be increased gradually. Especially when victim is
infant, be carefully not to be too strong, not to blow in too much air.
Keep giving artificial respiration until victim start breathing without help,
or being passed to medical aid.
