Model essay on the theme class meeting of typhoon prevention safety education in schools in 2020

The so-called storm surge means that when the typhoon moves to the land, due to the typhoon's strong wind force and low air pressure, the sea water accumulates strongly in the direction of the coast, the tide level rises sharply, and water waves come to the coast. The following is the theme class meeting of typhoon prevention safety education in school, which I compiled, hoping to provide reference for everyone.

Fourth, the class teacher's summary

1, 1994, 94 17 typhoons landed in Rui' an, Zhejiang Province, and the "wind and rain tides" converged, affecting 7.5 million mu of crops in the province and killing 1 126 people; 1996, Typhoon No.9608 landed in Keelung, Taiwan Province Province and Fuqing, Fujian Province, causing more than 54 million mu of crops to be affected, and more than 700 people died in 10 provinces and cities. 1997, Typhoon 97 1 1 landed in Wenling, Zhejiang Province and Jinzhou, Liaoning Province successively. 10 affected more than 6,543.8 billion mu of crops in many provinces and cities, with 240 deaths. 200 1 Guangxi was hit by two typhoons "durian" and "ute" continuously, and there was a large-scale rainstorm or heavy rain. Tens of millions of people in 48 counties and cities in the region were affected, and more than 400,000 people were once trapped by floods.

2.1In July, 1995, more than ten students in Wutang Town, Suixi County, Guangdong Province were struck by lightning while sheltering from the rain under a big tree, causing two deaths and six injuries on the spot.

3.1August 3, 995, in a management area of Lecong Town, Shunde City, Guangdong Province, three children were struck by lightning just after they came out of the water and landed. One child of 1 1 died unfortunately, and the other two children fell to the ground.

4.65438+June1214 pm in 1996, a female intern surnamed Xie was struck by lightning on her way home by motorcycle in Bingcun, Meizhou City, Guangdong Province.

5.1June, 996 14 At 7: 00 p.m., a group of college students from the Department of Mechanical and Electrical Engineering of Guangdong University of Technology played football in the school football field in the rain. Five people were knocked down by the thunder, and two of them were taken to hospital for emergency treatment.

6. In June, 2008, Longmen County suffered a once-in-50-year flood disaster, with 40,250 people affected, 2,683 flooded houses and 2 1 collapsed houses. According to preliminary statistics, the total loss is nearly 50 million yuan. About 20 houses collapsed in five towns in the east of Boluo County, affecting more than 5,000 people and causing direct economic losses of about 5.5 million yuan.

Thirdly, analyze the causes of typhoon, lightning and flood.

After learning about the dangers of typhoons, lightning strikes and floods, students continue to understand the causes of these disasters. Students discuss in groups 10 minutes, and one representative of each group expresses his opinions. The teacher summarizes:

1, there are two main causes of typhoon formation: first, the ocean temperature is relatively high; The second is rich water vapor. Typhoons only occur in tropical oceans. The sea surface temperature there is very high, so that the lower air can fully accept the water from the sea surface. It is also the place with the richest water vapor on the earth, which is the main driving force for the formation and development of typhoons. Without this motivation, the typhoon will dissipate even if it is formed. Secondly, there is a certain distance from the equator, and the deflection force generated by the earth's rotation plays a certain role, which is conducive to the development of cyclone circulation and the strengthening of airflow convergence. Third, the tropical sea surface is simpler than the mid-latitude sea surface. Therefore, the air over the same sea area can often remain stable for a long time, so that typhoons have enough time to accumulate energy and brew wind. So generally speaking, there are more typhoons in coastal areas.

2. Lightning is a natural phenomenon, which is essentially a spark discharge in thunderstorm clouds in the sky. The light produced during discharge is lightning, and the loud noise produced by lightning when the air is heated and expanded rapidly is thunder. Opening the secret room in a thunderstorm is easy to be struck by lightning, causing injury and even death.

3. The precipitation in southern summer is influenced by manual summer monsoon. Due to the weak influence of the incoming summer monsoon and the strong influence of the continental air mass, the summer monsoon always stops in the south and cannot go deep into the north. Therefore, the situation of flooding in the south and drought in the north appeared.

Fourth, how to take preventive measures.

Thinking: (1) The typhoon is coming. How do you avoid it? (2) When you are walking on the road, the sky is raining heavily, and there are thunder and lightning. How do you avoid lightning strikes? (3) How to save yourself in case of flood?

(Students express their opinions, and the teacher summarizes)

1, How to prevent typhoons and floods:

(1) Before the typhoon comes, people should be moved to safety in time.

(2) Never stay in dangerous houses, sheds, temporary buildings (such as fences), projects under construction, amusement facilities, cranes, construction elevators, scaffolding, telephone poles, trees, billboards, iron towers and other places.

(3) High-altitude objects will be blown down by strong winds, which is prone to fatal accidents. Balcony, roof flowerpots, roof sundries, scattered items, tools, building materials, etc. are easily blown down by the wind, causing casualties. These materials should be transferred in time.

(4) Heavy rain may cause accidents in water conservancy projects. In case of danger, our personal safety may be affected, so in case of danger, we should transfer the relevant personnel to a safe place in time.

2, how to prevent lightning:

(1) can't stay in the building.

(2) Pay attention to close the doors and windows.

(3) It is not advisable to use a shower.

(4) should not be close to the building exterior wall and electrical equipment.

(5) It is not advisable to enter low-rise buildings (structures) without lightning protection equipment, such as shacks and sentry boxes.

(6) It is not advisable to hide under a big tree.

(7) It is not advisable to hold up objects in the wild.

(8) It is not advisable to work or play on the water surface or at the junction of land and water.

(9) It is not advisable to drive a motorcycle and ride a bike quickly.

(10) Outdoor ball games are not suitable.

(1 1) Stop using mobile phones in thunderstorm weather.

Verb (abbreviation of verb) abstract

Students, today we discussed the hazards of typhoons, lightning strikes, floods and other disasters, as well as the causes of these disasters, and especially explained how to prevent students from encountering these unexpected situations. So here we sum up the following experiences: First, when encountering these unexpected situations, we should first keep calm and don't panic. Second, we should report these unexpected situations to teachers and schools in time. Third, school personnel on duty and security personnel should often patrol the school. If you find any unexpected situation, you should immediately report to the supervisor on duty and the unit leader to start the emergency procedure. Fourth, if anyone is found injured, you should immediately organize rescue or call 120 to send him to the hospital. More importantly, natural disasters are not terrible. If students learn more safety knowledge, pay more attention to safety education, start from me and keep safety awareness in mind, then our campus will be more civilized, more harmonious and safer.

Fan, the school typhoon safety education theme class meeting

Teaching purpose: let students know the common sense of typhoon prevention and the knowledge of prevention after typhoon.

Teaching process:

First, understand the typhoon.

1. Understand the concept of "typhoon".

What we usually call a typhoon is a tropical cyclone. The so-called tropical cyclone refers to a low-pressure vortex that rotates rapidly on the surface of tropical or subtropical oceans, often accompanied by strong winds, heavy rains and storm surges.

2. The folklore of typhoon.

3. Understand the characteristics of typhoons.

4. Understand the classification of typhoons.

5. Understand the hazards of typhoons.

Typhoon has brought abundant rain to vast areas and become a rainfall system closely related to human life and production. However, typhoons always bring all kinds of injuries. Because of its sudden and destructive power, it is one of the most serious natural disasters in the world.

The destructive power of typhoons is mainly caused by strong winds, heavy rains and storm surges.

(1) Strong wind

Typhoon is a huge energy pool, and its wind speed is above 17m/s, even above 60m/s. According to the measurement, when the wind reaches 12, the wind pressure per square meter on the plane perpendicular to the wind direction can reach 230kg.

(2) Heavy rain

Typhoon is a very strong rainfall system. When the typhoon lands, the rainstorm center can drop by 100 ~ 300mm a day, even up to 500 ~ 800mm. Typhoon rainstorm is strong, flood occurs frequently, spreads widely, and is fierce and destructive.

(3) Storm surge

The so-called storm surge means that when the typhoon moves to the land, due to the typhoon's strong wind force and low air pressure, the sea water accumulates strongly in the direction of the coast, the tide level rises sharply, and water waves come to the coast. The storm surge of a strong typhoon can raise the coastal sea level by 5~6 meters. Storm surge meets astronomical high tide level, resulting in high-frequency tide level, which leads to tidal overflow, seawall burst, washed away houses and various building facilities, flooded towns and farmland, and caused a large number of casualties and property losses. Storm surge will also cause coastal erosion and land salinization caused by seawater intrusion.

6. What should we do after the typhoon warning is issued?

Typhoon warning signal is divided into four levels according to approaching time and intensity, which are represented by blue, yellow, orange and red respectively.

(1) Typhoon blue warning signal

Icon:

Meaning: It may be affected by tropical depression within 24 hours, with an average wind force of above 6 or a gust of above 7; Or it has been affected by the tropical depression, with an average wind force of 6-7, or a gust of 7-8 and may continue.

(2) Typhoon yellow warning signal

Icon:

Meaning: It may be affected by tropical storms within 24 hours, with an average wind force of more than 8 or a gust of more than 9; Or it has been affected by tropical storms, with an average wind force of 8 ~ 9, or a gust of 9 ~ 10 and may continue.

(3) Typhoon orange warning signal

Icon:

Meaning: It may be affected by a strong tropical storm within 12 hours, and the average wind force may be above 10, or the gust 1 1 above; Or have been affected by a strong tropical storm, the average wind force 10 ~ 1 1, or the gust112 may continue.

(4) Typhoon red warning signal

Icon:

Meaning: It may be or has been affected by the typhoon within 6 hours, and the average wind power can reach more than 12, or it has reached more than 12 and may continue.

7. Enjoy the damage caused by the typhoon.

Second, how to prevent typhoons

1. What should I prepare before the typhoon comes?

(1) Pay close attention to the typhoon trend, pay attention to the reports of relevant media, or learn about the latest typhoon situation through the "96 12 1" meteorological consultation telephone, Putuo radio and television and meteorological website.

(2) According to the possible impact of typhoon, the Meteorological Observatory issues forecasts to the public in three forms: news, alarm and emergency alarm. At the same time, according to the possible impact of the typhoon, blue, yellow, orange and red warning signal will be released to the public from light to heavy, and the public should take timely preventive measures according to the forecast.

(3) Before the typhoon comes, the public should make full preparations, such as food, clean water, medicines, emergency lights and related necessities.

2. What should I do if the typhoon comes?

(1) When the typhoon comes, you should check whether your preparation measures are perfect and whether the residential area is safe. You should obey the arrangement of the local government and relevant departments, and don't move in dangerous areas. If told to evacuate, it should be done immediately to ensure personal safety.

(2) Close the doors and windows, check whether the doors and windows are firm, remove the hanging objects, check whether the facilities such as circuits and gas are safe and whether the telephone lines are normal.

(3) High-rise residential residents should transfer flowerpots and sundries placed on the balcony exterior wall and roof to a safe area to avoid injuries caused by strong winds.

(4) Unless there is an emergency, residents should never go out at will.

(5) When going out in an emergency, try to take a taxi or bus, and don't walk on rivers, seawalls and small bridges, and don't drive in areas affected by strong winds.

(6) Stop all dangerous operations at high altitude and outdoors; Stop all kinds of open-air collective activities and large indoor gatherings.

(7) Passengers in tourist attractions should obey the arrangement of scenic area managers, stop all outdoor activities, evacuate to safe areas or rest in hotels in time, and don't go out at will.

(8) Ships going to sea should return to Hong Kong in time to take shelter from the wind, and irrelevant personnel on the ship returning to Hong Kong should rest in a safe place in time.

(9) Primary and secondary schools, kindergartens and nurseries may decide to suspend classes temporarily according to the intensity of typhoon.

(10) People living on the hillside should be alert to the landslide and debris flow disasters caused by typhoon and rainstorm, and transfer the danger signals as soon as possible.

(1 1) Residents living in the lower reaches of reservoirs and mountain ponds should follow the arrangement of the local government and move immediately when they move.

(12) If a ship encounters a typhoon on the way, it should contact the township government and the maritime department as soon as possible, report the location and ask for help. Maritime distress alarm telephone: 12395.

(13) Aquaculture personnel should immediately move to a safe place to avoid the wind.

(14) When there is water in front of the house, you should not walk by old experience at this time, and try to avoid the water. There is really no way around it. You'd better test it with a wooden stick first. First, it is waterproof. Second, it is necessary to eliminate dangerous situations such as underwater manholes.

(15) When you see a wire blown off the road, don't touch it with your hands. Especially in rainy days, the accumulated water is very conductive and cannot be approached. Call the power hotline 95598 immediately to inform the power repair personnel. If there is a sudden power failure at home, it is best to unplug the computer, TV and other power supplies and turn off the lights. Use emergency lights or candles for lighting at home. At the same time, ask 95598 about the cause of the power outage.

(16) users of solar water heaters should pay attention to two points: first, fill the water heater with water; The second is to unplug the plug and cut off the power supply of the water heater.

(17) Don't travel to areas where typhoons pass, and don't go swimming or sailing on the beach during typhoons.

(18) Vulnerable groups, such as the elderly, the disabled, and patients who have no children to take care of at home, should seek help from the local government, neighborhood offices, communities, villages, medical aid agencies and civil affairs departments in time when they are in urgent need of help due to the typhoon.

(19) When driving out, you should carefully consider whether you should wade in the water when you encounter water on the road. If the accumulated water is more than half of the tire, you can't wade. If the water is not deep, stop first to judge whether there are deep pits or obstacles on the ground. Before you decide to wade, you should turn off the air conditioner and audio equipment and close the doors and windows. When driving on the road with stagnant water, be sure to keep a low speed to prevent water from splashing on the electrical appliances at the upper part of the engine and causing flameout. If it goes out, don't light it again. You can push the car away from the stagnant water section. You can't drive too fast immediately after leaving the road with water, because the brake pads are not sensitive after splashing water. You should drive at a low speed for a while, and then drive normally after the water on the brake pads is evaporated.

What should I pay attention to after the typhoon?

1. Don't forget the post-disaster epidemic prevention.

Pay special attention to personal hygiene after the disaster, wash your hands frequently and drink boiled water. If drinking water is polluted, bleach and bleach should be used for disinfection. Wash the fruits and vegetables, and cook the food. It is best not to eat raw seafood to avoid intestinal infectious diseases. Do a good job in cleaning the surrounding environment

2. Don't buy suspicious food

After the typhoon, it is necessary to strictly control the "disease from the mouth". Vegetables and fruits should be carefully selected before buying, soaked in water for more than half an hour when cleaning, and peeled before eating; Drowned livestock and dead fish are inedible. Be careful when you go shopping. Never buy food of unknown origin. Because individual vendors will deliberately shoddy the food that was flooded or expired in the typhoon. If you encounter such a situation, you can report it to the health supervision department.

Don't forget to remove the rubbish.

After the typhoon, leaves, silt and domestic garbage are everywhere on both sides of the street, which is easy to breed various diseases. If there are flooded food or typhoon-damaged items at home, clean them up in time.

4. Don't walk under rickety trees or billboards, and try to choose public transportation such as buses.

After the typhoon, some trees and billboards have been destroyed for a day and a night, which is far away. You must be careful when passing through such a section, and you'd better make a detour. Never pass directly to save time.

5. Don't connect and disconnect wires at will.

Whether the wires at home fall or you see the wires broken by the wind on the road, if you are a professional electrician, you should stay away for safety reasons. Every year, people regret the casualties caused by private wiring, and a momentary carelessness will cause lifelong regret. Discovered disconnection, whether charged or not, should be regarded as charged, keep a safe distance from the disconnection point, and report to the electric power department in time.

6. Don't travel blindly.

After the typhoon, the probability of disasters such as mountain rock collapse and subgrade damage increases, and even people and cars may fall into the mountain stream if they are not careful, so it is best not to travel at this time.

Fourth, the class teacher's summary

Fan Wensan, the theme class meeting of typhoon prevention safety education in school

First, the teaching focus:

1, flood, rainstorm, lightning, typhoon and other disastrous weather prevention education

2, drowning prevention education

3, food poisoning prevention education

4. Traffic safety education

5, electricity safety education

Second, the class meeting link

1, Discussion: What are the potential safety hazards in summer?

2. What should we do in the face of potential safety hazards in summer?

Three, flood, rainstorm, lightning, typhoon and other disastrous weather prevention education

1. There is abundant rainfall in summer, and it is also a frequent season for floods, rainstorms, thunder and lightning, typhoons and other disasters. These disasters will bring many hidden dangers to students.

2, according to the characteristics of the geographical environment in the region, targeted safety education to deal with disaster weather. In case of heavy rain, thunder and lightning, snowstorm and other bad weather. Don't choose to travel by bike.

3. Pay attention to the cultivation of students' observation ability and the excavation and development of local knowledge of disaster weather in the school area.

Fourth, prevention of drowning education.

1. It is very hot in summer. Swimming and playing in the water are students' favorite sports and entertainment. At the same time, there is much rain in summer, the water level of ponds, rivers, lakes, reservoirs and bunkers rises, the accumulated water is deep, and the safety hazards of swimming and paddling increase, so many waters are not suitable for students to swim and

Play.

2. Educate students not to play in unsafe waters. Prevent students from drowning accidents.

3. Teach students to swim and improve their swimming skills. Necessary measures should be taken to scientifically prevent drowning accidents. In addition to mastering the basic skills of swimming, we should also train students how to save themselves when there are signs of drowning (such as being entangled in aquatic plants or cramping their legs) and carry out corresponding training. In the process of offering swimming lessons, we should also take corresponding preventive measures to prevent accidents.

Five, food poisoning prevention education

1, the summer climate is hot, microorganisms multiply quickly, food is easy to go moldy and deteriorate, and food poisoning accidents are easy to occur. Food poisoning prevention education and food hygiene education should be carried out in time.

3. The school strengthens the sanitary management of the school canteen. To publicize and educate students about food hygiene and safety knowledge, improve students' awareness of food hygiene and safety and self-protection ability, and prevent food poisoning incidents caused by eating unclean food or toxic and harmful substances by mistake.

Sixth, traffic safety education.

1. In summer, the days are long, students spend more time outdoors after school, and the chances of encountering traffic safety hazards will also increase.

2. Conduct timely and effective traffic safety education for students in combination with students' regular modes of transportation and actual cases. Remind students to pay attention to traffic safety on the way to and from school, don't chase and fight on the road, don't cross the road obliquely, don't take the expressway, and deliberately avoid vehicles.

Seven, electricity safety education

1, there are many kinds of electrical appliances in summer, and the power load is large, which is prone to electric shock and electrical fire.

Disasters and other accidents.

2. Conduct power safety education for students.

3. The electricity safety education in student dormitories is particularly important and should be organically combined with the management of student dormitories.

8. Conclusion: Students, don't forget to pay attention to safety in daily life and learn to protect yourself. Always keep safety knowledge in mind and pay attention to safety everywhere.
