High voltage safety warning
Precautionary measures
The voltages used to power this equipment are
potentially lethal. Even 110 volts can kill.
Whenever possible, the following precautionary
measures must be taken before any work is
carried out inside the equipment:
•
Switch off all high-voltage power supplies.
•
Check the operation of any door interlocks
and any other safety devices.
•
Completely discharge all high-voltage
capacitors.
It should be noted that interlocks and safety
devices are normally located only at regular
access points, and high voltages may be exposed
during dismantling.
Never work alone on high-voltage equipment!
First aid in the event of electric
shock
Normally, even a high voltage electric shock will
not kill instantly. The victim can still be revived
even when his breathing and heart-beat have
ceased.
Could YOU save someone’s life?
In the event of electric shock, the correct actions,
performed quickly may well save the victim’s
life. Make sure you know what to do!
Immediate action:
While shouting for help, remove the source of
power from the victim. Switch off the supply if
possible, or using a dry, non-conductive material
(rubber gloves, broom handle etc.) to insulate
yourself, separate the victim from the source. If
the voltage exceeds 1000 volts, switch off the
supply and be ready to catch the victim. Take
care- do not become a victim yourself.
Commence first aid on the spot. Continue to shout
for assistance till someone arrives.
1 Lay the victim flat on his back and loosen
any tight clothing (collar, tie, belt etc.).
2 Open his mouth and check for and remove
any false teeth, chewing gum etc.
3 Check if the victim is breathing. If not,
check if his heart is beating. The pulse is
normally easily found in the main arteries
of the neck, either side of the throat, up
under the chin.
If his heart is beating but he is not breathing,
commence artificial respiration. If the victim’s
heart is not beating, commence external cardiac
massage (ECM). Continue to shout for assistance
till someone arrives.
External cardiac massage
1 Kneel beside the victim. Place the heel of
one hand in the centre of his chest, at a
position half way between the notch
between the collar-bones at the top of his
chest, and the dip in the breast-bone at the
base of his rib cage. Place the other hand
on top of the first.
2 Keeping the arms straight and using your
entire weight, press down rapidly so that
the breast bone is depressed four- five cm,
then release the pressure. Repeat
rhythmically at a rate of one cycle per
second. This will be hard work, but keep
going. His life depends on YOU. Do not
worry about breaking his ribs - these will
heal if he survives.
