Emergency Action for Accidents Involving Electricity
•
Never touch an overhead line - even if it has been brought down by machinery, or
has fallen. Never assume lines are dead.
•
When a machine is in contact with an overhead line, electrocution is possible if
anyone touches both the machine and the ground. Stay in the machine and lower
any raised parts in contact or drive the machine out of the lines if you can.
•
If you need to get out to summon help or because of fire, jump out as far as you
can without touching any wires or the machine - keep upright and away.
•
Get the electricity company to disconnect the supply. Even if the line appears
dead, do not touch it - automatic switching may reconnect the power.
