What is the step voltage and how it is so dangerous

Walking through the forests in search of mushrooms or heading for hunting or fishing, we often pass under the existing power lines. And sometimes you can see that one of the power line wires lying on the ground. So, do not approach him. Perhaps he is still alive, and nearer to it, you can get a step voltage.

In this article, I'll tell you what it is and how to behave correctly if you see broken wire.

What is the step voltage

To begin, let's find out what the step voltage. Stepper called stress which is caused by electric current flowing through a conductive ground or floor. This voltage is the potential difference between two points of the surface, spaced at a distance of one step.

Do not think that if the wire lying on the ground, the line is definitely off. There are regimes where "land" (wire break and touch his land) is not a prerequisite for triggering protective automation. Therefore, the wire saw, it is better not to approach close to it.

Considered a safe distance of 8 meters from the place the wires touch the surface.

How to leave the danger zone

If you have found out too late the wire and approached him closer than 8 meters, the first thing to stop and, without taking your feet off the ground, pinch them together.

After this so-called goose-step, keeping the heels off the ground, leave the eight-meter zone.

Important. Do not try to jump on one leg, because you can stumble and then the current can go the way of hand-foot, which is much more dangerous than the path of the foot-leg.

After this, note the location of the damage the wires and let the local city networks.

The liberation of man from the impact of the step voltage

If while walking you find that the person is unconscious, and next to it there is a broken wire, it is not necessary for him to run recklessly, you can also get energized.

The first step is get the best possible long dry stick. Walk up to the wire goose step and shuffling with a stick as far as possible drop wire. After that, drag away the victim away from the line, check for a pulse and breathing.

Call an ambulance if you need to produce and chest compressions and ventilation until the ambulance arrives.

Note. Of course, in reality, not everyone knows how to do chest compressions and artificial respiration, but correct to reject the wire to pull the person to call an ambulance and you just have to.

conclusion

Step voltage - a very dangerous phenomenon, and to know the basic safety measures need to know young and old alike. Therefore, seeing the broken wire, do not go near it, do not let go, and the other as soon as possible inform the urban network.

Remember your safety and health in your hands. Take care of yourself!
