Sweet "Electric shock" hurts, and reality is injured. You deserve to have these four major first aid Dafa

Each human body has biological currents (generally small) and unique magnetic fields. When the two people have the same current magnetic field and the same frequency, the two sides can induces each other, just like the radio receiving signal of the wireless radio station, which is probably the "electric shock" in the lyrics. However, the electric shock in real life is a very dangerous thing. What harm can the electric shock bring to our human body? How to perform on -site first aid after electric shock? What is the safety voltage of the human body?

The feeling of electric shock is not sweet, it is very painful and dangerous.

Electric shocking price

Electric shock is a common name for electrical injury. It usually refers to the tissue injury or dysfunction caused by the transmission current caused by air or high -voltage electricity through the air or other conductive medium that pass through the air or other conductive medium. stop. High -voltage electricity with more than 1,000 volts can also cause severe burns. Lightning injury (lightning strike) belongs to the category of high -voltage electricity damage.

There are many reasons for electro -injury. The most important thing is caused by the lack of safety and electricity. For example, installation and maintenance of electrical appliances, electric wires do not operate according to procedures, and hang clothes on the wire. More than 60%of human tissues are composed of moisture containing conductive substances. Therefore, the human body is a conductor. High temperature, high humidity and sweating can reduce the surface resistance of the human skin, which causes electrical injuries. In an accident, when the wire is broken into the human body or a person hiding from the rain under the big tree or being hit by lightning with an iron handle umbrella, it may be injured.

Four major first aid Dafa after electric shock

After the electric shock, how should I first aid? Of course, according to the environment and conditions of the electric shock site, the safest and most fast ways are taken -cut off the power supply or leave the electric shock from the power supply.

Common method:

After the electric shock, first find a way to safely cut off the power to turn off the power: If the electric shock occurs near the home or near the switch, it is the easiest and effective way to quickly turn off the power switch and turn on the power gate. Pick off the wire: If you cannot find or disconnect the power in time, use a dry wooden stick and bamboo pole to drive the wires from the electric shock, and fix this wire to avoid electric shock. Cut the circuit: If the place where the power switch is far away from the power switch, especially the rainy days, it is inconvenient to approach the electric shock to pick up the power cord, and you can use insulation pliers or dry wooden handles at the scene at the scene. The wire is cut off. "Pulling" electric shock: If the electric shock is unfortunately lying on the iron shell machine, the rescuer can put a dry wooden board or plastic plate under his feet, and use a dry and insulating cloth strip, rope or clothes to form a rope -like cover. Pull it away from the power shock.

While rescue others, you must do your own insulation

While rescue others, we should also pay attention to preventing our own electric shock. First of all, we must strictly maintain the insulation of the electric shock, do not directly contact the electric shock, and the selected equipment must also have insulation performance. If the insulation performance of the equipment is used is not sure, you need to dry the insulation items such as dry wooden blocks and thick plastic blocks on the foot to make you inside the earth. Secondly, when it comes to rain, when rescue the electric shock in the wild, the original insulating equipment may lose insulation performance due to wetness. When rescue others, pay more attention to protect themselves. In addition, when rescing high -voltage electric electric shock personnel, you need to pay attention to the step voltage. It is best to cut off the power supply outside 20 meters. It is indeed necessary to enter and exit the dangerous areas. It is necessary to use a single -foot jump or big -step jump to avoid both feet at the same time.

To know the safety voltage

Electric shocks will not only damage the body or even life -threatening. Isn't all electric shock dangerous? Obviously there is a special case -it is okay when we hold the battery poles, because the voltage of ordinary batteries is only 1.5 volts. So, what is the safety voltage of the human body? Industry regulations: The safety voltage is not higher than 36 volts, the continuous contact voltage is 24 volts, and the safety current is 10 mAh. The degree of harm of electric shock to the human body mainly depends on the size of the human current and the length of power. The greater the current intensity, the greater the fatal danger; the longer the duration, the greater the possibility of death. According to the Om Law (i = U/R), we can know that the size flowing through the human body is related to the external voltage and human resistance. In addition to the human resistance of the human body, the clothes, shoes, pants and other resistors other than the human body should also be added. Although the resistance of the human internal tissue is generally about 1,000 ohms, there are many factors that affect human resistance, such as humid skin and sweating, with conductive dust, increase the contact area and pressure with the charged body, and clothes, shoes and socks. Wet oil pollution and other conditions can reduce human resistance. Therefore, the size of the human body is usually not calculated in advance. Therefore, in order to determine the safety conditions, we often do not adopt safety current, but use a safe voltage to estimate. The key to the death shock is to see the size of the current. The sparks emitted when taking off sweater are as high as tens of thousands of volts, but no continuous current is formed, so it will not be used to die. Therefore, specific problems should be analyzed. In normal circumstances (dry), the safety voltage is below 24 volts. The smaller the humid resistance, the larger the voltage, the larger the current, the larger the current.

Although electricity has greatly enriched our daily life, the consequences of electric shock are also very serious. Both electricity and science are double -edged swords. Only by correctly can we benefit us all human beings, so we must standardize electricity and electricity in life, so as to safely and conveniently use the convenience of electricity to bring us the convenience brought by us.
