Dog peeing tray is a common thing for dogs, especially when encountering pillars, dogs like to pee here, and more importantly, once a dog pees here, more dogs will come here to urinate.
Unfortunately, a dog in Shanghai was killed by an electric current while urinating next to a street lamp. After the inspection, it was found that the lamp pole of the street lamp had been seriously rusted, and some of the wires had been exposed, and there was a serious leakage of electricity. When the dog pees, it just happens to urinate to the leakage part, because the urine is a conductor, causing the current to flow from the bare wire through the dog's body, resulting in electrocution.
After this matter was fermented on the Internet, different people had different voices, and some people blamed pet owners for walking their dogs without a leash, resulting in the dog's urine corroding the light pole for a long time. There are also people who think that the property is more faulty, and if it is not a dog this time, it may be a person next time.
And for this matter, we are not concerned about who is right and who is wrong, but that peeing can actually lead to electric shock, so the question is, if humans accidentally urinate to the place where the electricity leaks when urinating, will it also lead to human electrocution?
In fact, contact with the electrified wire does not necessarily cause human electric shock, the most common phenomenon is that the high-voltage line can cause human electrocution through the fishing line, but the bird standing on the high-voltage line will not do anything.
This is because the birds are very small, their foot spacing is also very narrow, the voltage between the two feet is almost the same, there is no potential difference, so that a closed circuit cannot be formed, so the current will not pass through the bird. However, if the feet of the birds are larger, it will cause the voltage between the two feet to be different, so that the current will pass through the birds, resulting in electric shock.
In fact, monkeys climbing on power lines are electrocuted and killed because of the large distance between their hands, forming a closed circuit.
The reason why the dog urinates will be electrocuted is actually that the distance between the urine and the foot is too large, forming a potential difference, so that the current passes through the body.
When humans urinate, if they accidentally urinate on the power line, then the urine may form a potential difference with the feet, causing the current to pass through, which may lead to electric shock.
Guangzhou once had a case of death due to urine and urine electric shock, at that time a man stood on the water pipe behind the overpass sanitation tool room, peeing on the high-voltage line on the side of the road under the bridge, because the railway high-voltage line was not wrapped in insulating glue, causing the man's entire body to be attracted by the high-voltage line, and then issued a "bang" sound, the man's clothes suddenly caught fire, burned for nearly 1 minute or so, the man fell down, died on the spot.
Of course, contact with bare wires does not necessarily lead to human electrocution. If a human stands on an insulator bench and only one hand touches the powered wire, it will not be possible to form a closed circuit, so there will be no current flowing from the human body, and humans are safer.
Second, if the shoes you are wearing are insulators and have sufficient thickness, it can also cause the line to fail to form a closed circuit.
Also, not all the current flowing through the human body will lead to human electrocution, the current that humans can withstand is about 10 milliamps, when the current flowing through the human body exceeds 25 milliamps, it will be difficult for humans to get rid of themselves, and they need the help of others. Among them, the greater the current flowing through the human body, the more dangerous it is to humans, and even lead to direct death of human beings.
Theoretically, boys and girls urinate on the electrified line, and the consequences are different, which is mainly related to the posture when urinating.
Men generally stand to pee, the height is high, the current must follow the urine to enter the human body, and the urine has a resistance, which means that if the voltage is not high, it may not cause male electrocution.
But unlike women, women's urination posture makes it seem as if women are in direct contact with the power-on circuit, so that they are more likely to be dangerous.
Since women's urination posture determines that women are more likely to be electrocuted, why are mostly male students?
The reason is actually very simple, women generally do not urinate on the side of the road, while many men will find a hidden corner to urinate, and even deliberately urinate on the pole.
In addition to contacting the power line when accidentally urinating, we must also pay attention to the safe use of electricity in life, and we should stay as far away from the high voltage line as possible, because the strong voltage can even break through the air. In the absence of insulation protection, just 10,000 volts of high-voltage electricity can break through the air.
The accident of electrocution death caused by pet dog peeing also gives us a wake-up call: stay away from charged objects, especially men when urinating, do not go near electric objects such as telephone poles and high voltage lines to avoid accidents.
If an accident does occur, the rescuer should not rush to pull away, but use an insulator to take it away from the leakage site.
