PRO CED URES

FOR AN ELECTRIC SHOCK

CASUALTY

Safety

The first priority for the rescuer is to avoid becoming a

casualty and making the situation worse for other

rescuers. It is essential to make sure it is safe to

approach and to check if the casualty is still connected

to the electrical current in any way directly (to a faulty

machine, apparatus or to a bare wire), or indirectly

(lying on an electrically conductive surface)

Procedure

DO NOT touch the casualty with your unprotected

hands Break the contact by switching off the current,

removing the plug or wrenching the cable free

If you are unable to isolate the casualty as already

described, you must stand on dry insulating material

such as a wooden box, a clean rubber or plastic mat, or

a thick pile of dry newspapers Then either:

c use a wooden or plastic

implement to free the casualty

from contact with the electrical

source, or

— wear rubber or plastic insulating gloves, if

available, to pull the casualty free, or

— if rope is available, without touching the casualty,

loop it around the feet or under the arms and pull

the casualty free.

Ensure there is no more danger If the casualty seems

unharmed, rest and reassure them and refer to a doctor

or a nurse. However, if the casualty is unconscious,

check breathing and pulse Send for help immediately.

Resuscitation may be needed

First aid action

Step A

Open the airway by

— turning the casualty on his/her back;

lifting the jaw and tilting the head back to open

the airway,

Step A

— carefully removing any obvious debris from

inside the mouth.

Step B

Check breathing by.

looking to see if the chest rises and falls,

— listening for breaths,

feeling breaths on your cheek

Step C

Check circulation (pulse).

— find the pulse by placing your fingers to the side

of the voice box and pressing down gently

Step C

Step B

The unconscious casualty, who is breathing and has a

pulse, should be placed in the recovery position and

monitored until medical assistance arrives

Mouth-to-mouth ventilation

If there is a pulse but the casualty is not breathing,

begin mouth-to-mouth ventilation as follows:

— Kneel beside the casualty. While keeping the

head tilted backwards, open their mouth and

pinch their nose (Step A)

Open your mouth and take a deep breath Seal

their mouth with yours and breathe firmly into it.

The casualty's chest should rise

ii Remove your mouth and let the casualty's chest

fall (Step B) If the casualty's chest does not rise

and fall, check that

• their head is tilted back sufficiently;

• you have a firm seal around their

mouth,

• their nostrils are closed completely,

• their airway is not obstructed

— Continue breathing into the casualty's mouth at a

rate of 12-16 times a minute until they are

breathing by themselves Then place the casualty

in the recovery position. If the casualty is not

breathing AND there is no pulse, Cardio-

Pulmonary Resuscitation (CPR) must be

carried out. CPA is mouth-to-mouth ventilation

combined with chest compression.

Cardio-Pulmonary Resuscitation (CPR)

— Give two breaths

— Find the bottom of the breast bone

— Two fingers' breadth above this, place the heel of

one hand along the breast bone Cover this hand

with the other hand, interlocking your fingers.

i Keep your arms straight and press down 4-5 cms,

15 times at a quicker rate than once a second

— Repeat mouth-to-mouth and continue the cycle at

the rate of two breaths to 15 compressions, with 4

cycles per minute.

There should be no pause between the cycles. Two

inflations should take approximately 5 seconds and 15

compressions should take approximately 10 seconds.

Continue until the casualty has been successfully

resuscitated, place in the recovery position if necessary,

or until more expert help arrives. Treat other injuries as

required.

To be competent at resuscitating effectively,

it is advisable to receive emergency first aid

training.
