bandage. Any loose skin or blisters should not be touched nor any lotions or
ointments applied to the burn wound;
8) If the person regains consciousness, treat for normal shock;

9) Remain with the person until they are taken to a hospital or local surgery.

It is important to note that electrocution by high voltage electricity is normally
instantly fatal. On discovering a person who has been electrocuted by high voltage
electricity, the police and electricity supply company should be informed. If the
person remains in contact with or within 18 m of the supply, they should not be
approached to within 18 m by others until the supply has been switched off and
clearance has been given by the emergency services.
High voltage electricity can ‘arc’ over distances less than 18 m, thus
electrocuting the would-be rescuer (Figure 14.3).

 Electrical fires and explosions

Over 25% of all fires have a cause linked to a malfunction of either a piece of
electrical equipment or wiring or both.
Electrical fires are often caused by a lack of reasonable care in the maintenance
and use of electrical installations and equipment. The electricity that provides heat
and light and drives electric motors is capable of igniting insulating or other
