First of all, let's understand the first problem, the reaction occurs completely different when electrocution, the first reason is the stress response of the human body when electrocution, the human body in direct contact with the current because of the stimulation of muscle spasm and paralysis, your joints will unconsciously bend and curl up, so if your palm touches the leakage part, you will hold the power supply by yourself and do not let go, if the electric shock part is the outside of the hand, the outside of the body, etc., after the electric shock, because the body curls up will be bounced off the power supply, so these are not passive, but the body active.
In addition, the magnetic field will also cause electric shock in two situations, in the case of a fairly high voltage, the body will also be electrocuted without direct contact with the power supply, when you step into the leakage area, the magnetic field in your body and the current magnetic field will repel each other, so you will be electrocuted.
And if an area is leaking because of the wire leakage and touching the ground, then the earth is also full of voltage, if you stand in this area with two feet one after the other, resulting in an electric potential difference, the current will form a path in your body, in this case, you will be stiff and unable to move after being electrified.
So the next question, how long does it take for a person to die after being electrocuted?
On July 3, 2023, a 10-year-old boy in Zhoukou City, Henan Province, died suddenly from electric shock because he hid and hid in a leaky air conditioner, and the process from electrocution to death took only a few minutes.
In May this year, a 9-year-old girl in Chongqing inserted her finger into an socket while playing, causing an electric shock, but the little girl did not die on the spot, and was sent to the hospital for emergency treatment, but 9 fingers were amputated.
From these gruesome cases, we can see that although most people who are electrocuted will stop breathing on the spot, electrocution will definitely lead to death.
When the voltage exceeds 36 volts or more, that is, 36,000 mAh, people will be in danger, but as long as the current flowing to the human body is 50 mAh, it may be fatal, many people know that our household current is 220 volts, if it is at home in contact with leakage electrical appliances and electrocution, then 3 to 4 minutes will be electrocuted, if it is out of the power supply after a few minutes and sent to rescue in time there is a possibility of survival, so if it is exposed to more than 220 volts of voltage, Then the person may be gone in seconds.
The fatal cause of electric shock is usually that the contact with strong voltage or direct current when the electric shock occurs, this current flows to the heart, resulting in cardiac arrest and sudden death, in addition, when the current flows to various parts of the body, it will also damage other tissues and organs, and when the current is high, it will also lead to organ failure and organ damage, which will also lead to death if the rescue is not timely, and like the previous 9-year-old girl's amputation, it is because the strong current causes the human body to produce huge heat,** and tissues thus being burned, in which case amputation is basically an option.
So now let's understand how to save yourself and others when you are electrocuted?
This is a real case that happened in July 2020, a little girl accidentally fell into the landscape river while playing in the park, and as a result, the little girl was screaming and spasms by the electricity leakage in the landscape river, and 3 adults rushed into the water to save people after hearing it, and as a result, all 4 people were electrocuted and finally 2 died and 2 were injured.
This case is a living wrong practice, when found that someone is electrocuted, many people's first reaction is to save people quickly, so they do not hesitate to reach out to pull, and the fatal is this action of reaching out and pulling, others must not use their hands to contact the electrocuted person when they are electrocuted, because the human body can conduct electricity, and your contact with the electrocuted person is equivalent to making yourself another circuit, and the current will flow from the electrocuted person to you causing you to also be electrocuted.
If there is no electric switch, quickly look for non-conductive objects around, such as wooden sticks, bamboo poles, rubber-wrapped objects, etc., and use these insulating objects to separate the electric shock from the power supply, but remember, you can not immediately approach the electric shock after the electric shock and the power supply are separated, you must make sure that the power is completely off before you can touch, and then call the emergency ** and wait for rescue.
And if the electrocution is yourself, you may be more panicked, this is unavoidable, after being electrocuted paralyzed at all, I don't know what to do, but in fact, the first few seconds of the electrocution people are still conscious, in these seconds you have to try your best to call for help, let the people around you notice you and then come to save you, if no one saves you, you will grab the insulating object with the other side of the body that has not touched the power supply, or roll the ground or kick the wall with your foot, which can help you get out of the power supply.
