Experience of safety education in the first lesson of summer vacation safety 1
Last Wednesday afternoon, in the third class, Teacher Zhang told us a class meeting on the theme of preventing drowning. Summer is coming, and many people who can swim will stick to swimming. Maybe this is the end of life. We know that there are more than 20 drowning people every day, and 90% of them can swim.
Swimming is one of children's summer sports, and it is also a boy's specialty. It can be said that some people's nightmares have begun to act. The teacher said that you can't go to lakes that don't know the water conditions, and you can't go to informal swimming pools, which will lead to safety accidents! However, some boys did not listen to the instructions and insisted on moving forward, which led to a tragic end.
Don't walk blindly in the street when there is a storm. When there is no flood, look at the manhole cover on the roadside. If there is no manhole cover in some places, immediately call the maintenance workers to repair it in time, and pay attention to your feet when there is a flood. There was a pregnant woman who was flooded in a rainstorm when she was shopping, but she went ahead and fell into the sewer. It was several days before she was discovered. Poor thing, one corpse and two lives! Some children stayed in the swimming pool for a long time to escape from summer. Some children swim too long and are exhausted, and suddenly get acute diseases in the water, especially heart diseases. No one will know when they will die.
The main cause of drowning death is that the trachea inhales a lot of water to hinder breathing, or because of dizziness and so on. The symptoms of drowning are: dyspnea, blue lips and nails, foam on the lips and nose, coma or cardiac arrest in severe cases. Hungry, too full and too tired to swim in the water.
Students, we must cherish our health, and don't be confused for a moment, which not only hurts ourselves, but also immerse our parents in grief.

Without health, there is no miracle, and without security, there is no hope for the motherland. I have benefited a lot since I watched the program "Caring for Life and Preventing Drowning". Every child may become a world champion, a famous writer or a pillar of the country in the future Olympic Games. But if there is no security, the hope of the motherland and society will be greatly lost, and the development of science and technology will be slow. Therefore, everyone should feel safe.
After the program "Caring for Life and Preventing Drowning" was broadcast, it told me a lot of safety knowledge about preventing drowning, and also warned all naughty children who love swimming not to swim under unsafe or unfamiliar conditions. Children who can't swim must learn as soon as possible to prevent accidents.
In the hot summer, the sun is like fire, and every child wants to go swimming, but it is also the time when drowning happens the most. So if you want to go swimming, you must be accompanied by adults and pay attention to safety, especially some naughty children. They always try to be brave, saying that they don't need lifebuoys or warm-ups, and some even swim with one hand. As a result, they got cramps while swimming. Swimming in places where you don't know the water conditions, so as not to cause unpredictable dangers, so everyone needs to remember these knowledge of preventing drowning, which is really deserved and effective for people!
I hope everyone will be healthy, study hard and never let the tragedy happen.

In hot summer, the cool river will tempt many students to take a bath. But students, do you know? The seemingly calm and gentle water surface hides mystery. The gurgling river tempts you, but when you jump up, you open your mouth and prepare to swallow you up. If you leave quietly like this, have you ever thought about your parents?
First, swimming safety points
1. Don't be too hungry or too full when entering the water. Don't go into the water for an hour after a meal to avoid cramps.
2. Try the water temperature before entering the water. If the water is too cold, don't go into the water.
3. When swimming in rivers, lakes and seas, you must be accompanied, and you can't swim alone.
4. Observe the swimming environment before launching. You can't swim here if there is a danger warning.
Don't swim in the canyon with unclear geographical environment. The water in these places is different in depth and cold, and there may be obstacles in the water that hurt people, which is very unsafe.
6. Before diving, make sure that the water depth here is at least 3 meters, and there are no weeds, rocks or other obstacles underwater. It is safer to enter the water with your feet first.
7. When swimming in the sea, swim parallel to the coastline. Those with poor swimming skills or insufficient physical strength should not get involved in the depths. Make a mark on the coast, pay attention to whether you are washed too far, and adjust the direction in time to ensure safety.
Second, how to prevent lower limb cramps when swimming?
You must warm up before swimming.
You should consider your physical condition before swimming. If you are too full, hungry or tired, don't swim.
Pull some water on your limbs before swimming, and then jump into the water. Don't jump into the water at once.
If you have chest pain while swimming, you can press your chest hard and wait until it is better. When you have abdominal pain, you should go ashore. It is best to drink some hot drinks or soup to keep warm.
Third, the self-rescue strategy of swimming and drowning in summer
How to ensure the health and safety of swimming and avoid drowning? Unfamiliar with the water situation, rushing into the water can easily lead to life-threatening.
(1) In case of unfortunate drowning, experts say that the drowning person should not panic, and should keep calm and actively save himself:
1. For people with cramps in their hands and feet, if they have cramps in their fingers, they can make a fist with their hands, then open it hard and do it several times quickly until the cramps are eliminated;
2. If the calf or toe cramps, first take a breath and float on the water, hold the toe of the cramped limb with the hand on the opposite side of the cramped limb, and pull it in the direction of the body. At the same time, press the knee of the cramped limb with the palm on the same side to help the cramped leg straighten.
3. If the thigh cramps, it can also be solved by lengthening the cramped muscles.
(two) for drowning people, in addition to actively self-help, but also actively carry out land rescue:
1. If there is mud, weeds and vomit in the mouth and nose of the drowning person, it should be removed first to keep the upper respiratory tract unobstructed.
2. If the drowning person has drunk a lot of water, the rescuer can kneel on one leg, bend his knees on the other leg, put the abdomen of the drowning person on his knees, hold the head of the drowning person with one hand, and press his mouth down on his back with the other hand to discharge the water.
3. If the drowning person is unconscious, breathless or stops breathing, artificial respiration should be carried out after the above treatment. The drowning person can lie on his back, and the rescuer can hold the nose of the drowning person with one hand, hold his chin with the other hand, take a deep breath, and then blow air into the drowning person's mouth with his mouth.
After blowing one breath, leave the mouth of the drowning person, release the hand holding the nose at the same time, and press the chest of the drowning person with your hand to help him exhale. This is repeated regularly, about 14-20 times per minute, which can be slightly slower at the beginning and accelerated appropriately at the later stage.
Fourth, drowning first aid.
Drowning is a common accident. Drowning can lead to suffocation and hypoxia. For example, if the heartbeat stops, it is called "drowning", and if the heartbeat does not stop, it is called "dying". This classification is of great significance to estimate the condition and prognosis, but the treatment principle is basically the same, so it is collectively called drowning.
1. After the wounded are carried out of the water, the water, mud and dirt in their oral cavity and nasal cavity should be removed immediately. Wrap your fingers with gauze (handkerchief) and pull the tongue out of the mouth, unbutton the button and neckline, keep the respiratory tract unobstructed, then pick up the waist and abdomen of the wounded and let him pour water with his head back. Or pick up the injured person's legs, put his abdomen on the shoulders of emergency personnel, and quickly run over to pour out the accumulated water. Or the rescuer takes a semi-kneeling posture, puts the abdomen of the injured person on the leg of the rescuer, makes his head droop, and presses his back with his hand to pour water.
2. People who stop breathing should immediately carry out artificial respiration, and mouth-to-mouth blowing is generally the best. The first aider is located on the injured side, hold the injured person's jaw, hold the injured person's nostrils, take a deep breath, and slowly blow into the injured person's mouth. When the chest is slightly lifted, relax the nostrils and press the chest with one hand to help exhale. Repeatedly and rhythmically (blowing 16 ~ 20 times per minute) until breathing resumes.
People with cardiac arrest should do chest massage first. Let the wounded lie on his back, with a hard board on his back, his head down and his back tilted. The emergency personnel are located on the side of the wounded. Facing the wounded, put the palm of your right hand flat on the lower part of the sternum and your left hand on the back of your right hand. With the help of the body weight of the first-aid person, he should push slowly, but not too hard to prevent fracture. Then he should press the sternum down about 4 cm, then loosen his wrist (keep his hand from the sternum) to restore the sternum, and repeat it regularly (60-80.
5. What should I do if my ears get water while swimming?
Because water has a certain tension, it forms a barrier after entering the narrow external auditory canal, which divides the external auditory canal into two sections, and because of the gravity of water, secondary pressure is generated between the water barrier and the eardrum, maintaining the pressure balance on both sides of the water barrier, making it difficult for water to flow out automatically. Sometimes there is a large cerumen obstruction in the external auditory canal, so it is easier for water to wrap around cerumen after entering the ear canal, and it is not easy to flow out.
After water enters the ear, it will cause deafness, dizziness and discomfort, so people often want to drain the water very urgently. Some people even use unclean clips, match sticks, small keys, etc. It can break the water barrier and make water flow out, but it is also easy to damage the external auditory canal and even the eardrum, leading to ear diseases.
After the water enters the ear, it should be discharged in time. The most common methods are:
1, one-legged jumping method: the affected ear is downward, and the water flows downward from the external auditory canal by the gravity of water.
2, external auditory canal method: you can press the tragus continuously with your palm or pull the auricle with your fingers; Or repeatedly open your mouth and move the temporomandibular joint, which can make the skin of the external auditory canal move up and down, left and right, or change the stability of the water barrier and pressure, so that water can flow out of the external auditory canal.
3, external auditory canal cleaning method: gently probe into the external auditory canal with a clean fine cotton swab, once you touch the water barrier, you can suck out the water.
Because the swimming pool or river water is unclean, the skin and eardrum of the external auditory canal are infected after the sewage enters the ear, or the water is improperly treated after entering the ear, which can often cause the following ear diseases, such as unclean ear digging. : otitis externa, swelling of external auditory canal, cerumenitis, suppurative otitis media.
If the above symptoms appear after entering the water, you should temporarily stop swimming and go to the hospital for examination and symptomatic treatment.
Students, we have learned so much today. I hope students can apply what they have learned.

Life is everywhere. In the endless stream of people, the beating heart and smiling face are fresh life; In the forest that exudes wisdom, the small trees that thrive in the sun and the towering trees of peace are full of vitality; In that vast sea, carefree fish and graceful corals are countless smart and beautiful lives. When you see the mother pregnant in October and the baby born, you will know that this will announce the birth of a new baby! Will you sigh, sigh the hard-won life? Therefore, life is precious, so we should "cherish life and prevent drowning"!
The stream is clear and cool, which makes people feel very comfortable. The water looks so gentle and calm. It will make you feel that it will be beautiful to jump into her arms, and you can't help jumping into her arms, but sometimes she will hold you. For example, on the morning of June 26th, 2000, Xu, a student from a school in our county 1 class, thought that the Oujiang River would be cold for a while because of the hot weather, so he jumped into its arms. As a result, he will never come back.
This river is cool, comfortable and fun. You want to stay with her for a while. Maybe you just want to shake her hand, or kick your feet and get close to her, but she will be furious. I remember one day in April, 20 _ _ _, at about noon 12, Zhu, a fourth-grade student in a primary school in our county, was playing with several classmates by the Oujiang River. Zhu was accidentally swept away by the angry river and left his relatives and friends.
The river is ruthless, scary and unpredictable. Maybe you think the river is so terrible that you won't touch her and be safe, but she won't let you go. For example, at 2 o'clock in the afternoon of February 29th, 2000, Luo Mou, a second-grade student of a central primary school in Hushan Township, Suichang County, accidentally slipped and fell into the stream while walking in front of her house, taking her life again.
So I will tell you a children's song; I have a wonderful plan to prevent drowning. The first plan is to be accompanied by an adult. Swimming without permission is dangerous, and it is important not to go to deep water. I have a wonderful plan to prevent drowning. The second plan is to warm up before swimming. Reaching out, kicking, bending over, bending over, preparation is essential. I have a wonderful plan to prevent drowning, and a third plan to relieve cramps. It's important to go ashore quickly. Drink some nourishing water to relieve fatigue. You should know the measures to prevent drowning and should not be conceited. Remember the word safety and stay away from danger.
Students, it is really important for primary school students to prevent drowning. For a better tomorrow, let's "cherish life and prevent drowning".

The hot summer has arrived, and the cool seashore, flowing rivers and streams bring people joy and comfort, but there are also potential security crises. From May to September last year, 89 primary and middle school students and children died of swimming drowning in all parts of the province, of which rural drowning accounted for 78%, local people accounted for 52%, children of floating population accounted for 4 1%, and primary and middle school students accounted for 85%. On May 20th this year, Zhou (male, from Linhai City, 13 years old, a student from Class 6, Grade 7, Dongcheng Middle School, Linhai City) drowned in the pool next to the rock warehouse in Dongcheng Town Village, Linhai City, and died after being rescued by the hospital. In the case of mastering swimming skills, remember the following safety points when swimming in summer:
1. Observe the swimming environment before launching. You can't swim here if there is a danger warning.
