How dangerous electrical current

We often do not realize the seriousness and danger of using an electric current. And all because it surrounds us from the very first minutes of life, and is next to us almost always.

an electric current does not in itself no odor or taste or color, it can not touch and see. But we can see his work in a burning light bulb running mixer and basking iron. And this force is very useful to easily become destroyed.

So what is the danger of current

First deleterious effects on human nerve fibers.

Next, - a thermal skin burns and even muscles (with significant values ​​of short circuit current).

Ours with you body also produces extremely low electrical impulses by which we can move. And when the body begins to pass current from the network, it is several times stronger than the walls of their native impulses and that's why at the moment a person is not able to control their muscles, and they randomly reduced.

Important. If necessary to verify the absence of voltage (and therefore current) on the conductor by touching. This is done only the back of his hand, like this.

This ensures that if the wire still has power, the hand, down, involuntarily bounces from live parts under voltage.

Threshold, after which the voltage and current and consequently, starts to be dangerous, it is recognized in the value of 50 V. A value of 100 V, is already recognized as a fatal. In these figures the amount of current is 100 milliamps.

Current is 30-50 mA is quite capable of provoking an unstable operation of the heart muscle, until it stops.

Important. Now you understand that the voltage of 220 volts is already extremely dangerous for human life and health.

thermal burns

Another negative impact on the current person it burns. Even at home, you can get burned. As a result of the short circuit at this point it is formed and a sharp increase of the current starts burning arc (welding effect). And if such an arc gets on your skin, burn provided.

chemical effect

The electric current other than the thermal burn, flowing through the blood and lymph systems of the body, also has an extremely deleterious effect on them. And it is not rare are cases that after the electric shock, people are starting to see the negative effects throughout the body.

As you can see from the facts above, electricity is extremely dangerous, though, and at the service in every home. Therefore, all the work and electrical wiring must be carried out in strict compliance with safety measures, as may depend on a person's life.
