2. Campus safety tips

1. In case of theft, students must handle it calmly, and do: (1) Call the police to the school security department or the local police station immediately, and at the same time block off the protection site, and no one can enter.

Don't rummage through the items at the scene, and don't see if your items are lost. This is of great significance for public security personnel to accurately analyze and judge the scope of reconnaissance and collect evidence.

(2) If suspects are found, students should be organized to intercept them immediately and try to capture them. (3) Cooperate with the investigation, answer the questions put forward by the public security departments and security personnel realistically, actively provide clues, and do not conceal the situation.

School security departments and public security organs have the obligation and responsibility to keep students confidential. (4) If the passbook is found stolen, you should report the loss to the bank as soon as possible.

Second, avoid fighting (1) Students should get along with each other in unity, courtesy, civilization and morality, so as to prevent social unhealthy atmosphere such as loyalty in Jianghu from eroding the campus. (2) When there are conflicts between students due to trivial matters of life (such as cooking in the canteen, occupying a seat in the library, playing sports on the court, etc.). ), students should be calm and restrained, learn to be tolerant, "take a step back and broaden the horizon", and never be emotional or impulsive.

(3) When a classmate is found fighting, the classmates at the scene should not stand by and do not add fuel to the fire. When people who hold the same view or fellow villagers are bullied, don't add fuel to the fire to avoid group fights.

(4) Students should strictly control the number of people and the amount of alcohol when drinking at the party. Especially for those students who are easily emotional after drinking, it is necessary to control the amount of alcohol and persuade them to drink less, so as to prevent troubles after drinking and cause adverse consequences.

Expanding school information security is a very important part of the whole social security work. It is directly related to whether young students can grow up safely and healthily, and to the happiness and social stability of thousands of families in Qian Qian, Qian Qian.

From 65438 to 0990, the World Health Organization issued a report. In most countries in the world, accidental injury is the most important cause of injury, disability and death of children and adolescents. In China, the highest accidental injury mortality rate of school-age children mostly occurs at school and on the way to school; Among teenagers of different ages, the highest accidental injury mortality rate is 15 to 19.

Accidental injury not only caused a large number of children's lifelong disability and premature death, but also consumed huge medical expenses and weakened the country's productivity. It not only brings pain and misfortune to children and families, but also causes great burden and loss to society, * * and schools.

According to the survey, from 1999 to 2002, there were more than 360 students in Beijing, and more than half of them had difficulties in handling accidents. Therefore, campus safety has become a hot issue of concern to all sectors of society.

Protecting every child and minimizing accidents that happen to them has become an important content of safety education and management in primary and secondary schools. Baidu encyclopedia-campus safety.

3. Children learn safety knowledge

Identify dangerous goods signs and stay away from places where dangerous goods are stored. Learn about dangerous goods signs with children, and know all kinds of common dangerous goods signs in real life, such as vehicles transporting special goods on the road and high-voltage boxes on the roadside. Know the identification of dangerous goods, know the relevant knowledge of dangerous goods, stay away from the place where dangerous goods are stored, and improve your knowledge and ability to protect yourself.

Understand the basic knowledge of fire protection. Many children have worked as firemen in the professional experience hall. Children are so earnest and dedicated when they put on helmets, fire suits and carry out tasks with hoses and guns on fire engines. After the firefighter bravely completed the fire fighting task, it is also necessary to popularize some real basic knowledge of fire fighting for children: for example, can all fire sources be extinguished with water? What substance burns when it meets water? Will the food we eat spontaneously ignite? What are flammable gases and liquids?

Enhance self-safety awareness. Give children some reading materials to supplement their safety knowledge. Through parent-child reading, increase safety knowledge, learn more common sense of safety self-help and enhance self-safety protection knowledge. For example, in case of fire, explosion and other dangerous events, call the police for help, clearly tell the rescuers where they are, leave the scene as soon as possible, judge the wind direction when fleeing, move upwind of the explosion point, and do not use the elevator when fleeing.

After the crisis, professional psychological support and intervention are essential. Let children know that when their lives suddenly change due to serious disasters, major life events or mental stress, they can get help by seeking professional psychological support and intervention.

In the face of this sudden major crisis, we need to learn and accumulate all kinds of safety knowledge and common sense with our children, and treat and handle the crisis correctly. Only by constantly learning all kinds of safety knowledge accumulated in life and practice can children use it when they need it in the future and better protect themselves.

4. It is urgent to hand-write the information about safety knowledge.

A, walking instructions 1, pedestrians must walk on the sidewalk, no sidewalk must walk on the side of the road; 2. Pedestrians are not allowed to chase and run in the roadway, and they are not allowed to suddenly turn and cross when the vehicle approaches; 3, are not allowed to pick up the car on the road, chasing the car, are not allowed to forcibly pulled up or parabolic hit the car; 4, are not allowed to play on the road, frolicking; 5. Preschool children must be led by adults when walking on streets or highways; Second, the boarding instructions 1 are not allowed to greet vehicles in the middle of the road; 2, motor vehicles are not allowed to be any part of the body out of the window; 3, when riding, are not allowed to stand, not allowed to eat in the car; 4. Don't get on or off by force, get off first and then get on, wait in line and get on in order; After getting off the bus, wait for the vehicle to leave. If you want to cross the road, you must walk safely. 5. Do not take overloaded vehicles or vehicles without passenger and sports licenses; Third, riding instructions 1, children under the age of 12 are not allowed to ride bicycles or tricycles on the road; 2. Before turning, slow down, turn around, reach out and don't turn suddenly; 3. Hands are not allowed to leave the handle and climb other vehicles or objects; 4. Vehicles are not allowed to drive in parallel, chase each other or meander; 5. Always check the performance of the car. You can't ride a bike when there is something wrong with its bell, brakes or other parts. You should repair it in time. 6, no umbrellas, no cycling with people; 7, are not allowed to learn to ride a bike on the road; There are two main ways to avoid fire casualties: first, being suffocated by smoke and toxic gases, and second, being burned by flames and strong thermal radiation.

As long as we can avoid or reduce these two hazards, we can protect our own safety and reduce the hazards. Therefore, it is possible to get a second life in a difficult situation by mastering some small skills of self-rescue in fire.

1. Fire rescue, always pay attention to the escape route. Everyone should know something about the structure and escape route of the building where he works, studies or lives, and be familiar with the fire-fighting facilities in the building and the methods of self-help and escape. In this way, in case of fire, there is no way out.

In an unfamiliar environment, we must pay attention to evacuation routes, safety exits and stairs, so as to escape from the scene as soon as possible at a critical time. 2. Put out small fires to benefit others. When a fire breaks out, if the fire is not big enough to pose a great threat to people, we should make full use of the surrounding fire-fighting equipment, such as fire extinguishers and fire hydrants, to control and put out the small fire.

Don't run around screaming in panic, don't ignore others and just "escape" yourself, and don't ignore a small fire and cause great disaster. 3. In case of sudden fire, keep calm and evacuate quickly. In the face of sudden smoke and fire, we must keep calm, quickly judge the dangerous place and safe place, decide the escape mode, and evacuate the dangerous place as soon as possible.

Don't blindly follow people, crowd each other and rush about. Only when you calm down can you come up with a good solution.

4. Get out of danger as soon as possible and cherish life. Love money like fire, life is more expensive than money. When you are in danger, it is very important to run away. You must race against time and remember not to be greedy for money.

5. Evacuate quickly and crawl forward. Don't stand when you leave the fire. Don't stand when the smoke is rolling, the sight is unclear and you can't breathe. You should climb on the ground or squat down to find a way to escape. 6. Make good use of this article. Don't get into the elevator and go to a dead end. In case of fire, you can use the safety exits such as stairs, or use the balconies, window sills and skylights of buildings to climb to the surrounding safe places, or slide down the stairs along the protrusions in building structures such as downpipes and lightning wires.

7. When the escape route is cut off and there is no rescue in a short time, you can find or create a shelter and insist on waiting for rescue. First of all, you should close the doors and windows that are on fire, open the doors and windows that are on fire, block the doors with a wet towel or cover the doors and windows with a quilt soaked with water, and then constantly spray the room with water to prevent fireworks from infiltrating and sticking to auxiliary materials.

8. Jumping off a building is skillful and won't harm your health. In case of fire, many people choose to jump off a building to escape. You should also talk about skills when jumping off a building. When jumping off a building, try to jump into the middle of the life-saving air cushion or choose the direction of pool, hood and grass. If possible, try to hold some soft objects such as quilts and sofa cushions tightly or open a big umbrella to jump down to slow down the impact.

9. Fire and your body roll on the spot. Don't run in the fire When your clothes catch fire, you should try to take off your clothes or roll on the spot to crush the flame. It is more effective to jump into the water in time or have someone water it and spray fire extinguishing agent on your body. 10. If you are in danger, don't forget to save others. Anyone who finds a fire should call "1 19" for help as soon as possible and report to the fire brigade (1) for emergency treatment.

(1) If scalded by hot water, immediately cool the affected area with cold water and take off the clothes. (2) When falling from a height, immediately make the falling person lie down calmly; If there is trauma, clean the wound with clean water or medicated soap and wrap it with gauze.

③ Dislocation: Keep the injured person in a comfortable posture, and apply cold water to the affected area, not hot compress. ④ Heatstroke: Quickly move the heatstroke victim to a ventilated and cool place, unbutton his coat, wipe his head with cold water or wipe his body with alcohol, and let the heatstroke victim drink more cold water, together with ten drops of summer medicine.

⑤ Food poisoning: While looking for an ambulance, send warm water, salt water or milk to the patient; Put fingers and other objects in the patient's mouth and throat to make him vomit. 6 flying objects hit the eyes; Rinse your eyes with clean water, and don't probe with your hands. If the eyes bleed, you can apply gauze lightly, add a layer of cold wet cloth and wrap it with a bandage.

(2) Home fire extinguishing method: 1, quickly dial the fire alarm number 1 19, explain the location, and wait for the fire truck at the intersection. 2. It is best to find a fire hydrant and put out the fire with washbasin, bucket and other appliances.

3, individual items on fire, to quickly move the fire to the outdoor fire fighting. 4. When the oil pan is on fire, cover the pan directly and turn off the power.

5. When the household appliances catch fire, cut off the power first, and then smother the fire with blankets and quilts. If it doesn't go out, water it again. 6. When the TV is on fire and smothered with blankets and quilts, people should stand behind the TV to prevent the CRT from bursting and hurting people.

7, gas, liquefied gas stove is on fire, you must first close the valve, covered with apron, clothes, bedding, etc. After soaking, pour water. 8. When putting out the fire, slowly open the doors and windows to avoid air convection to accelerate the spread of the fire, and the flame suddenly rushes out to hurt people.

9. Flammable near the burning point.

5. Seat belt knowledge

Seat belts Seat belts Edit this paragraph 1. The safety belt personal fall protection system of bungee jumping equipment is a set of products necessary to connect workers with fixed points, which can completely prevent falling from a height or completely eliminate this situation.

Using these products alone cannot provide fall protection. However, if these components can be well combined, they will form a personal fall protection system which is extremely important for workplace safety and overall fall protection plan.

Personal fall protection system products mainly include hanging points, hanging point connectors, intermediate connectors and full-body seat belts. Second, the ideal seat belt function process of the car seat belt is: first, tighten it in time and "press" people on the seat without hesitation at the first moment of the accident. Then, relax moderately. When the peak impact force has passed or people can be protected by airbags, relax the seat belt appropriately.

Avoid rib damage caused by excessive tension. The most advanced seat belts are equipped with pre-tightening devices and tension limiters. Let's take a look at their functional principles.

1, seat belt pretensioner accident, people forward, seat backward. At this time, if the seat belt is too loose, the consequences are likely to be: passengers slip out from under the seat belt; In other words, people have touched the airbag, and at this time, the seat belt can't be tightened in time because the tension margin is too large, that is, it can't eat part of the impulse in advance as expected, but hand over all the burden to the airbag. In both cases, passengers may be seriously injured.

But the problem is that the seat belt is installed correctly. Where does its loose space come from? First, the occupant's clothes have a certain thickness, and there is a certain loose space hidden in the seat belt device, which cannot be eliminated, but it should be eliminated as much as possible in the event of an accident.

What do we do? For this reason, this seat belt pre-tightening device appears, which is responsible for providing instant tightening of the seat belt. Its function process is: firstly, a probe is responsible for collecting collision information, and then an electric pulse is released and transmitted to the gas generator to detonate the gas.

The gas generated by the explosion expands rapidly in the pipeline and presses against the so-called ball chain, which makes the ball move forward in the pipeline and drives the pawl disk to rotate. The pawl plate is connected with uranium, and the safety belt is wound around the shaft.

To put it simply, the gas pressure makes the ball move, the ball drives the pawl plate to rotate, and the pawl plate drives the shaft to rotate-the pretensioning function of the seat belt is realized instantly. The whole process from accident perception to seat belt pre-tightening is only a few thousandths of a second.

There is a cavity at the end of the tube for holding the ball. 2. After the accident of seat belt tension limiter, the seat belt has been tightened under the action of pre-tightening device.

However, we hope to reduce the tension of the seat belt immediately after the peak pressure has passed, so as to reduce the pressure of the occupants. This special task is accomplished by the seat belt tension limiter: on the seat belt device, there is a pre-tightening device as mentioned above, and the seat belt is wound under it. Inside the shaft core is a steel torsion bar.

When the load reaches the predetermined condition, the torsion bar begins to twist, which loosens the seat belt to a certain extent and realizes the tension limiting function of the seat belt. Under the joint action of seat belt pretensioner and seat belt tension limiter, the protection ability of seat belt has almost reached the ideal state.

As the saying goes, advanced seat belts can really provide reliable safety protection for passengers. ● Topic: Have you fastened your seat belt? Since the advent of seat belts, I don't know how many lives have been saved.

With the appearance of airbags, the safety factor of drivers and passengers has also been greatly improved. However, many people do not pay attention to the importance of seat belts and airbags, and "knowingly commit crimes" and always take chances.

In order to better protect passengers, airbags have become the standard safety configuration of most modern cars. However, when driving and riding, especially in cars with airbags, you must fasten your seat belts! Because the development and design of airbags are based on the limited protection function of seat belts, seat belts and airbags constitute an auxiliary restraint system (SRS), and only by cooperating with each other can the auxiliary protection function for drivers and passengers be fully exerted. When there is a strong collision in front of the car, the driver's body moves forward quickly due to inertia. At this time, the seat belt will try its best to "pull" the driver's body and absorb part of the impact energy. At the same time, the airbag will expand and fully open with lightning speed. Then the driver's upper body sinks to the airbag, and the gas begins to escape from the exhaust port of the airbag at a uniform speed, absorbing most of the impact energy; Then, the rider leans back and returns to his seat.

The whole process is almost instantaneous, and the driver and passengers are completely passive. In this case, passive reliance on the auxiliary occupant protection system is the only choice. If the seat belt is not fastened before the collision, the airbag will hurt the driver and passenger.

Without the restraint of the seat belt, not only part of the impact energy cannot be "detached" from the driver, but also the rapidly expanding airbag will collide with the rapidly moving driver, and the huge impact force generated by the rapid expansion of the airbag will hit the driver's head and chest heavily. It is conceivable that in this "collision", the driver's head and chest will be seriously injured, and the airbag has become the "culprit" that hurts the driver.

That's why you should always fasten your seat belt! Finally, did you fasten your seat belt? The characteristic of this pretensioned seat belt is that at the moment of collision, when the occupant has not moved forward, it will tighten the webbing first, immediately tie the occupant tightly to the seat, and then lock the webbing to prevent the occupant from leaning forward, thus effectively protecting the safety of the occupant. The retractor, which plays a major role in pretensioned seat belts, is different from ordinary seat belts. It not only has the function of ordinary retractor to take up the webbing, but also can strengthen the binding force on the passengers at about 0. 1s when the vehicle speed changes sharply, so it also has a control device and a pre-tightening device.

There are two kinds of control devices: one is electronic control device, and the other is mechanical control device. There are many forms of pre-tensioning devices. The common pre-tensioning device is deflagration type, which is guided by gas.

6. Asking for information about safety

Harmful factors in soil and their prevention and control

The quality of land in the living environment is also closely related to human health. Everyone knows the harm caused by pathogen pollution, so I won't explain it here. People may not pay much attention to the harm caused by chemical pollution. The chemical pollution of the land may be due to the fact that the residential area was used before it was built. This kind of land may be polluted by industrial waste residue and wastewater, or by pesticides. These pollutants may gradually seep out of the ground. Even entering the house seriously affects the health of residents. There is a canal at the junction of the northern United States and Canada. It's called Ralph Canal. The canal was originally planned to be built into a tourist area, but it was stopped halfway due to lack of funds, leaving only a dry river. A few years later, many chemical plants and pharmaceutical factories were built around the canal, and wastewater and waste residue were discharged into the canal. A few years later, residential areas were built in the local area, and many residents lived in them. In winter, children often play and skate in the canal. Gradually, the child developed a rash and chronic poisoning, and even the fetal malformation rate and abortion rate of pregnant women increased. According to expert appraisal, it is caused by industrial wastewater and waste residue in this area. In a bungalow area in the north of China, the incidence of cancer among residents is particularly high. After investigation, this bungalow used to be the original site of a chemical plant built by indigenous methods. The equipment was simple and often leaked during production, which seriously polluted the ground and foundation there, but after the factory moved out. Therefore, the choice of land is very important before the establishment of residential areas. It is necessary to consult the relevant land use management files, clean up the land before construction, and carry out targeted cleaning according to the past use to ensure the cleanliness of the land in residential areas.

After the completion of the community, it should also be managed frequently. Rainwater, sewage and garbage will pollute the land, and clogged sewers will form smelly puddles. The more garbage is piled up, the more toxic gases will be produced after many organic substances are corrupted. Among them, hydrogen sulfide gas is the most toxic. Hydrogen sulfide smells like rotten eggs, but at very high concentration, it will paralyze people's respiratory center, and people will soon suffocate before they can smell the eggs. It can be seen that the acute poisoning caused by hydrogen sulfide is very fast, and its attack speed can be described as "lightning" death. It can be seen that the clean management of land is very important and cannot be ignored.

Due to geological reasons, some areas have high background of radioactive materials. In buildings in such areas, more radioactive radon and its daughters will be infiltrated, which is also a carcinogen.

So before building a house, it is also very important to know the geological characteristics of the foundation there.
