Composition of electrical safety knowledge 1
With the development of science and technology, the use of electricity has become very common. However, do people know how to use electricity correctly?
In winter, the cold wind is biting, and people will use heaters at this time, but there are many safety hazards. Electric blanket, someone will use it in winter night. In order to keep warm, they will turn the temperature to the maximum. When the baby wets the bed at night, the electric blanket will touch the water, and the current will be transmitted to the baby with the water, which will lead to tragedy. Rechargeable hand warmers are often used, but it should be noted that charging for too long is easy to cause explosion; Don't leave when charging, and don't squeeze hard when using; Do not use it when charging.
As the hot summer is coming, people will use refrigeration appliances to drive away the heat. At this time, the electricity consumption will be much larger than in other seasons. In summer, the electricity consumption of almost every household is greatly increased, so replacing fuses with other metals will not avoid fires.
I once heard one thing, because of electricity: one afternoon, several friends were together, bored, and wanted to find a game to play. I saw a small house, no one lived in it, and all the sockets were exposed. At this time, a courageous boy said, "let's try to touch the socket with an iron bar and feel the tiny current." Hemp and fun! " Several others agreed, so they soon found an iron bar. The boy who proposed to marry him had an easy time alone. When the others saw that he was playing well and nothing happened, they all let go and were eager to try. But just as they were playing, they heard a burst of thunder and saw a bunch of lightning. Some timid people say, "Stop playing! A close call. It's lightning outside, you will get an electric shock! " "Afraid of what! Coward, if you dare not play, go home! We play ours! " The leader said arrogantly.
Slowly, the sky outside is getting darker and darker, and the wind and rain are mixed with dazzling lightning and thunder, but several children are still playing with electricity there. A flash of lightning went straight into the room. At that time, only one boy fainted as soon as he touched the socket. The other two men were dumbfounded at once and pulled him directly with their bare hands. Who knows? In this way, all three people fainted. Later, when someone found them, it was too late ... the current took several young lives mercilessly.
Also, under a telephone pole in a small town, such a tragedy happened in thunderstorm weather: there was a very busy person who kept calling and answering the phone on rainy days. That day, he just walked under the telephone pole and was making a phone call. It happened that a beam of lightning split down and passed directly into the human body along the mobile phone signal, leading to "the machine crashed and people died."
There are more such incidents, and bloody facts attack people's hearts. These events are also warning us: use electricity safely and cherish life. Everyone's life is only once, and if it is lost, it will be lost forever.

With the development of the times, there are more and more places to use electricity in life. Incorrect use of electricity also brings us many dangers. Electricity is a kind of energy. If we don't pay attention to safety, it may bring us harm.
Therefore, safe use of electricity is a compulsory course for each of us. Students, maybe it's some good habits that you inadvertently solved a disaster.
Safe use of electricity starts with me. The simplest thing is that we should get into the habit of turning off the lights. Not only electric lights, but also all electrical appliances. When we don't use them, we need to disconnect the power supply. Do not leave them in standby and power-on state. Once the electrical appliances are aged, a short circuit accident may occur, leading to a fire. And summer is coming, the weather is hot, and we use more electricity at home. So pay attention at this time. Load problem of power supply. For example, a wiring board will be marked with power, and the appliances we connect to it will also be marked with rated power. If the total power is greater than the patch panel, it is dangerous. If used for a long time, the circuit board will be overloaded and will heat up. Once the heat becomes more, the wires will burn and cause danger.
Therefore, we must pay attention to the danger of electricity safety. Enhance your awareness of electricity safety. Ensure our healthy life.

In recent years, the trend of short video in various short video apps on the network has emerged one after another. Many young people have conducted dangerous experiments in order to gain eyeballs, regardless of their own safety. Over time, many people will imitate the actions of these online celebrities.
A sad thing happened recently, which caused an uproar on the Internet. On the afternoon of August 22nd, 20 19, there was a girl Xiaozhe in Zaozhuang, Shandong province. Because she imitated a short video online, made popcorn with cans, and alcohol exploded, she was burned, and the burned area reached 96%. Later, due to serious infection, he died at about 1 1 on September 5, 2065438.
Reading this news report gave me a profound warning. In fact, as early as my sixth grade summer vacation, I followed the physics teacher's experiment class and completed this physics experiment with safe and effective guidance and the company of my parents. Under one operation, I enjoyed eating the fragrant and sweet popcorn fried by myself. However, without basic physical knowledge and professional guidance, there are still great security risks in this experiment. If every step is supported by good conditions, the safety of the experiment can still be guaranteed. However, in order to gain eyeballs on the Internet, online celebrities did not remind us of any risks. Various fancy actions in the video led to the tragedy that the resolution of the little girl was not enough.
I remember that in recent years, dangerous videos popular on the Internet, such as "Ice Bucket Challenge", "High-altitude selfie" and "Falling stars fall to show off their wealth", have been imitated in various ways. There are even two people running on the highway to shoot Tik Tok. These people don't take their life seriously at all, but only pay attention to it, which leads many children to imitate it for fun and novelty, causing great security risks.
Lack of safety awareness and poor resolution are actually one of the main reasons for the error. We should put safety first. Although the behavior of online celebrities is fashionable, it is very dangerous. Refuse to imitate blindly, safety first!
