◦An electric shock
occurs when
someone comes in
contact with an
electric energy
source.
or
◦It is the physiological
reaction or injury
caused by electric
current
(AC/DC) passing
through the human
body

An electric shock can have no
injury at all
Burns (which are the most
common)
Cardiac arrest due to the
electrical effect on the heart
Muscle, nerve, and tissue
destruction from a current
passing through the body
Death (electrocution)

What to do at THE time of electricWhat to do at THE time of electric
shockshock
 Disconnect the power supply. Don’t even touch the victim until you
are sure that the power supply is turned off. Be especially careful
in wet areas, such as bathrooms, as water conducts electricity. It
may be safer to turn off the electricity supply to the building if
possible to be absolutely sure.
 Or if the current can't be turned off, use a non-conducting object,
such as a broom, chair, rug, or rubber doormat to push the
person away from the source of the current. Do not use a wet or
metal object. If possible, stand on something dry and that doesn't
conduct electricity, such as a rubber mat or folded newspapers

What to NOT do at the time ofWhat to NOT do at the time of
electric shockelectric shock
Do NOT touch the person with your bare
hands if the body is still touching the source
of electricity
Do NOT apply ice, butter, ointments,
medications, fluffy cotton dressings, or
adhesive bandages to a burn
Do NOT remove dead skin or break
blisters if the person has been burned
After the power is shut off, do NOT move
the person unless there is a risk of fire or
explosion 113386
First AidFirst Aid
 Check for a person’s response and breathing.
It may be necessary to commence
cardiopulmonary resuscitation (CPR).
 If the breathing is steady and they are
responsive, attend to their injuries. Cool the
burns with cool running water for 20 minutes.
Never put ointments or oils onto burns. If the
person has fallen from a height, try not to
move them unnecessarily in case they have
spinal injuries. Only move them if there is a
chance of further danger from the
environment (such as falling objects).
 Talk calmly and reassuringly to the person..
 Be calm and Don’t panic
 AND don’t forget to call for ambulance in the
mean time
123386
TreatmentTreatment
Examine patients completely, including for
traumatic injuries
Resuscitation
Analgesia
Wound care
cardiac monitoring for 6 to 12 h for the patient
with following
Arrhythmias
Chest pain
Any suggestion of cardiac damage
Pregnancy
Known heart disorders
133386
In addition to burn injuries,AC can freeze
the patient's hand to the current source,
while DC can throw the patient, causing
injury.
Although skin burn severity does not predict
the degree of internal damage, internal
damage is more severe if the skin has low
resistance.
Refer patients with significant electrical
burns to a specialized burn unit and, if
significant internal damage is suspected,
begin fluid resuscitation.
