STAY SAFE AROUND FALLEN POWERLINES
Fourteen persons were
killed and four seriously injured when they came in contact with a high-voltage
supply wire in eastern Indian state of Bihar early this week.
Eyewitnesses said a truck carrying five cattle heads skidded and rolled
into a ditch past midnight on the outskirts of a village in Patna district
of the state.
The truck, as it rolled down the ditch hit an electric pole and 11,000 kilovolts
high-tension wire fell by the road side.
Two persons and the five animals died in the accident. This was not the
end of the tragic story. Next morning when villagers from a nearby village
reached the site to rescue the victims, they were caught unawares and electrocuted
by the high-tension wire.
Such tragic incidents
are not uncommon and at times claim several lives. Most of the times it
is our sheer ignorance.
Electricity always seeks the easiest path to the ground. It tries to find
a conductor, such as metal, wood, water -- or the human body, which is 70%
water.
Electricity does strange things to the human body. It contracts muscles, and frequently the person who comes into contact with a live conductor cannot release their grip.
It burns, destroys
tissue and muscle mass, and frequently causes ventricular fibrillation,
a condition where the electrical impulses of the heart are interrupted and
overpowered, so the heart will not beat properly. The muscles controlling
the respiratory system may fail. In many cases, death follows shortly after
electrical shock.
Power lines are not insulated. So if one comes in contact with equipment
that is in contact with a power line or the power line itself, electricity
will instantly pass through you, causing a harmful -- or fatal -- shock.
Before you approach any person affected by a power line anticipate potential safety problems.
Consider all overhead lines to be energised, no matter what they look like. There is always a hazard zone around power lines and stay outside it. Have lines barricaded or temporarily de-energized, if possible. Continually warn others about power lines and other electrical hazards.
Remember electricity, like
fire is a good servant but a bad master so treat it with respect.
