ARTIFICIAL RESPIRATION (MOUTH-TO-MOUTH)
(a) START MOUTH-TO-MOUTH BREATHING IMMEDIATELY.
SECONDS COUNT. Do not wait to loosen clothing, warm the
casualty, or apply stimulants.
(b) ASSESS RESPONSIVENESS OF CASUALTY. Do not jar
casualty or cause further physical injury (Figure 1)
(c) IF POSSIBLE, SEND A BYSTANDER TO GET MEDICAL
HELP. Do not leave casualty unattended (Figure 2)
(d) CHECK CAROTID PULSE (Figure 3)
(e) LAY CASUALTY ON HIS/HER BACK and place any
available jacket or blanket under his/her shoulders.
(f) TILT THE HEAD BACK AND LIFT THE CHIN to open the
airway (Figure 4)
(g) PINCH CASUALTY’S NOSE AND EXHALE TWO SLOW
BREATHS INTO CASUALTY (Figure 5)
(h) REMOVE YOUR MOUTH and check for breathing (Figure 6)
(i) CONTINUE GIVING ONE BREATH EVERY FIVE SECONDS
without interruption. If any air is retained in the stomach after
exhalation by casualty, press gently on stomach to expel air.
(j) IF CHEST DOES NOT RISE CHECK for obstruction in
casualty’s mouth: clear foreign material using your finger,
tissues, etc. Use chin lift and recommence mouth-to-mouth
breathing.
(k) WHILE MOUTH-TO-MOUTH BREATHING IS CONTINUED
have someone else:
(a) Loosen casualty’s clothing.
(b) Keep the casualty warm.
(l) DON’T GIVE UP. Continue without interruption until the
casualty is revived, or until a doctor pronounces the casualty
dead. Four hours or more may be required.
(m) DO NOT PROVIDE ANYTHING ORALLY while victim is
unconscious.

GENERAL RULES FOR TREATMENT FOR BURNS, BLEEDING, AND SHOCK
1. After casualty has revived, treat for injuries and shock.
2. Reassure casualty.
3. Try to make him comfortable.
4. Keep him reasonably warm but do not apply heat.
5. If thirsty, liquids may be given but no alcohol (no liquids should be given in cases of severe burns).
6. Treat burns or wounds. Infection danger in treating burns or wounds is very great so ensure hands are
clean and do not handle affected areas more than necessary.
7. Do not apply salves, grease, etc. to burns.
8. Do not remove burned clothing which adheres to the skin or break blisters.
9. Cover the burn with a dry sterile dressing, piece of sheeting, etc.
10. Bandage lightly over blisters where care must be taken to cover and not to break.
11. If severe bleeding of wound, elevate affected area, except in the case of a fracture.
12. Expose wound and apply pressure.
13. Apply dressing, pad and bandage.
14. For burns and bleeding, immobilize injured part using splints if necessary and keep patient in restful
position during removal to hospital or expert medical attention.
15. In all cases, send for medical aid immediately.

ELECTRIC SHOCK - RESCUE METHODS
Electricity can damage the body in a number of ways. It may interfere with the proper functioning of the nervous
system and the heart action, it can subject the body to extreme heat and can cause severe muscular contractions. The
path that the current of electricity takes through the body is important. Currents which pass from hand to hand or
from hand to foot may pass directly through the heart and upset its normal functioning. This threat to life is related to
the amount of current or amperage that will flow through a victim's body. Very little current (as little as 10 milliamps)
can result in severe shock or death.
Speed in the application of first aid measures is absolutely essential in cases of electrical injury. As soon as the victim
is freed safely from the source of the electrical current, if breathing has stopped, artificial respiration should be
commenced immediately. If the carotid pulse cannot be felt, external cardiac massage should be commenced
simultaneously. Resuscitation should be continued until the patient is breathing on his own or until medical aid
arrives. Survival rates can be quite high if cardio-pulmonary resuscitation is started within 3 to 4 minutes of the injury
being received.
ACT AT ONCE - DELAY OR INDECISION MAY BE FATAL
1. Turn OFF the electrical source.
2. Commence artificial respiration immediately.
3. Treat for burns, bleeding and shock.
REMOVING A CASUALTY FROM ELECTRICAL CONTACT
LOW VOLTAGE - 0 to 240 volts (household use)
Switch off the current, if possible and time permits. If the switch cannot be located immediately and the supply is
through a flexible cord or cable, the current may be shut off by removing the plug or even breaking the cable or
wrenching free. Never attempt to shut off current by cutting cord with a knife or scissors.
If the current cannot be shut off, the greatest care is necessary in removing the casualty. Household rubber gloves,
rubber or plastic hose (if there is no water in them), a dry unpainted stick or a clean dry rope can be used to free
victim.
HIGH VOLTAGE - 240 volts and up (industrial machines and power lines)
Do not touch any person or equipment in contact with a wire.
Use a dry unpainted pole, clean dry rope, dry rubber or plastic water hose to separate the casualty from the contact.
Keep as far away as possible.
Do not touch the casualty until he is free.
