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.
