Please write down three common fire prevention knowledge you know.

Daily fire prevention is the most important. It is the best preventive measure to develop good living habits and master common sense of fire prevention and fire safety:

1. Develop good habits, don't touch the unlit cigarette butts and kindling at will, and don't smoke on the bed or sofa after drinking, fatigue and going to bed.

2. In summer, mosquito-repellent incense should be put on a special shelf, and don't be close to curtains, mosquito nets and other flammable items.

3. Don't store inflammable and explosive articles such as gasoline and alcohol at will, and strengthen safety protection when using them.

4. Be especially careful when using open flame, and don't place flammable and combustible materials near the fire source.

5. Welding and cutting operations have great fire risks. Before operation, you must know the flammable and combustible materials nearby. Before operation, the flammable and combustible materials nearby must be removed. During operation, there should be a special person to prevent the fire caused by spattering of high-temperature welding chips. After homework, check whether there is a fire.

6. In case of gas leakage, close the valve quickly, open the doors and windows, don't touch the electrical switch box and use naked flame, and notify the professional maintenance department in time.

7. Check the circuit frequently to prevent aging, short circuit and leakage. Worn circuits should be repaired and replaced in time.

8. Circuit fuses (chips) are blown. Do not use copper wires or iron wires instead. It is recommended to install automatic air switches.

9. Don't overload electricity, and don't pull and connect wires.

10. Before leaving the residence or going to bed, check whether the electrical appliances are cut off, whether the main power supply is cut off, whether the gas valve is closed and whether the open flame is extinguished.

1 1. Don't pile sundries in corridors, stairs, fire exits, etc. , and ensure the smooth passage and safe exit.

What do you know about fire prevention in summer? 1. In hot weather, household appliances are prone to fire. With the arrival of hot weather, the number of electrical equipment such as air conditioners, refrigerators and electric fans has increased greatly, and the lines of electrical equipment are overloaded, and the insulation of power supply is damaged, which leads to short circuit fire, or the motor of electrical appliances is wet with water, which means that the insulation strength is reduced, and the short circuit burns out the motor and catches fire.

Note: Don't use water and foam extinguisher to put out the electrical fire without cutting off the power supply! Otherwise, rescuers are in danger of getting an electric shock at any time. In case of fire, call 1 19 in time.

2. The high temperature caused the car to catch fire. In summer, the power cord of some cars is short-circuited or overloaded, which leads to the increase of engine temperature and poor engine ventilation equipment, thus leading to auto-ignition; Leaking gasoline is the most terrible combustible. Once the fuel leaks and the mixture reaches a certain concentration, an open flame will appear, leading to spontaneous combustion accidents. External perfume, lighters, air fresheners, lighters, charging treasures and other items are prone to explosion when placed at high temperature for a long time.

Note: The vehicle is mainly inspected and maintained on a regular basis, and a fire extinguisher should be kept on the vehicle at all times (regularly check whether the fire extinguisher can be used normally), so as to be prepared. In case of fire, call 1 19 in time.

3. Flammable and explosive gases are prone to fire and explosion accidents. When residents use the stove, they should be guarded at all times and cannot leave people, in case the flame in the middle goes out, in case of fire, gas leakage and explosion. When igniting, you must follow the procedure of igniting first and then opening the valve to deflate. It is forbidden to knock and knock the liquefied gas tank, and it is forbidden to bake and heat the liquefied gas tank with fire. Always check whether there is any leakage in stoves and pipes, and whether the hoses are aging. If there is any leakage, stop using it immediately, open the doors and windows, do not use naked flames and electrical switches, and report to the gas supply department. It is forbidden to install, expand, dismantle and change pipelines, valves and pipelines without permission. Flammable and explosive articles are strictly prohibited to be stored around the gas stove.

Precautions: In case of gas leakage, call the fire alarm number "1 19" immediately, and the personnel will leave the site quickly.

4. The high temperature in the construction site is easy to cause fire. In the process of welding and cutting, the container will explode, which will easily lead to the death of workers on the spot, and even cause the explosion of the whole factory or production system, resulting in disastrous consequences. The management of open flames and key fire prevention parts is lax, and cigarette butts, matchsticks and electric appliances are randomly thrown to ignite combustible materials or bake combustible materials, resulting in fire accidents. In the construction site, there are many scattered lines, construction machinery and lighting equipment, and most of them are set outdoors, which is easy to get wet and age. Once there are electrical faults such as leakage short circuit or overload, it may cause fire.

Precautions: It is forbidden to use naked flames in places with fire and explosion hazards on the construction site, and a fixed smoking room should be set up on the construction site to prevent smoking.

Please write down what you know about disaster prevention and mitigation of middle school students.

First, earthquake safety.

1. In case of an earthquake in a theater, gymnasium, etc. You should be calm, especially when there is a power failure at the scene. Don't shout and don't crowd. You should squat down or hide under a row of chairs, pay attention to avoid hanging objects such as chandeliers and electric fans, and protect your head with a leather bag. After the earthquake, listen to the command of the staff and evacuate in an organized manner.

2. During the earthquake, when you are in shopping malls, bookstores, exhibition halls, etc. You should choose solid counters and commodities such as low furniture. ) or columns, and squat down in the inner corner, protect your head with your hands or other things, avoid glass doors and windows, or squat down in the passage, waiting for the earthquake to subside and evacuate in an orderly manner.

Students in class should hold their heads and close their eyes quickly under the teacher's command, and never run around or jump off a building. After the earthquake, they should leave the classroom in an organized way and go to the nearest open area for shock absorption.

4. The stadium where the competition is going on should immediately stop the competition, stabilize the mood of the audience, prevent confusion and crowding, and evacuate to the outside of the stadium in an organized and step-by-step manner.

Four Common Sense of Self-help in Earthquake

1, don't worry when there is a big earthquake.

Destructive earthquake takes only 12 seconds on average from when people feel the vibration to when buildings are destroyed. In this short time, don't panic, and make a quick choice according to your own environment to ensure safety. If you live in a bungalow, you can run to the door quickly. If you live in a building, don't jump off a building. You should immediately cut off the switch and gas, take refuge in places with small spans such as toilets, or under tables and beds, and evacuate quickly after the earthquake to prevent strong aftershocks.

2. Many people find a hiding place first.

In schools, shops, theaters and other places where people gather, if you encounter an earthquake, you should avoid panic. After the earthquake, they should immediately hide under tables, chairs or solid objects and evacuate in an orderly manner. Teachers and other field workers must calmly instruct people to take electric shocks on the spot and never take the lead in running around.

Step 3 stay away from dangerous areas

If you encounter an earthquake in the street, cover your head with your hands and quickly get away from the building and go to the center of the street. If you encounter an earthquake in the suburbs, you should pay attention to stay away from cliffs, steep slopes, river banks and high-voltage lines. Moving cars and trains should stop at once.

4, buried to save physical strength

If you are unfortunately buried under the rubble after the earthquake, try to stay calm and try to save yourself. When you can't get out of danger, you should save your strength, try your best to find water and food, create living conditions, and wait patiently for rescuers.

Second, fire safety

Without fire, people can't live. However, if fire is improperly used or managed, fire will happen, which will seriously threaten people's lives and property and cause great losses to national construction and development. Fire safety is very important, and fire control work includes two aspects: first, fire prevention; The second is fire fighting. In this regard, we teenagers should know something and master some basic knowledge.

What should be paid attention to in fire prevention?

There are many measures to prevent fire. Teenagers should first start with the little things in daily life:

1, don't play with fire. Some teenagers are curious about fire and often play games with fire behind their parents and teachers, which is very dangerous. When playing with fire, once the fire spreads or leaves unfinished fire, it is easy to cause fire.

2. Don't smoke. Smoking is harmful to health and easy to cause fire. We must abide by the student code and school rules and regulations and resolutely put an end to smoking.

3. Take care of fire control facilities. In order to prevent fire and fire accidents, fire hydrants, fire extinguishers, fire sandboxes and other fire-fighting facilities have been set up in residential buildings and public places, and safe passages for evacuation have been left in case of fire. We should consciously care for fire control facilities and ensure the smooth passage of safety.

How to pay attention to fire prevention at home?

Family fires are often caused by careless use of fire and improper use of electrical appliances. Teenagers should pay attention to:

1. Cook with a stove. The stove should be placed at a safe distance from flammable wooden furniture. In rural areas, you should stay away from firewood.

2, drying clothes should be watched, people can not leave for a long time.

3. Don't store flammable items near the fire.

4, when making a fire, don't use kerosene, gasoline combustion, in case of violent burning fire.

5. Take out unburned ashes and cinders and dump them in a safe place to prevent other objects from burning and catching fire.

6, the use of household appliances to meet the safety requirements, not disorderly open, so as not to cause safety performance decline, cause a fire.

7. Be careful when using hot appliances (such as electric irons), so as not to make them ignite flammable items.

8. When electrical appliances are used or personnel leave, turn off the power supply in time to prevent electrical appliances from overheating.

9. Use gas appliances to prevent gas leakage, and turn off the gas source after use.

10, the gas tank should be used away from the fire source; Check regularly to ensure that gas facilities and appliances are in good condition.

How to pay attention to fire prevention in school?

There are also fire safety problems in schools, and the following points should be noted:

1, do not bring matches, lighters and other kindling into the campus, and do not bring inflammable and explosive articles such as gasoline and firecrackers into the campus.

2. When the experimental class needs to use alcohol lamps and some flammable chemicals, it should be carried out under the guidance of the teacher and in strict accordance with the operating requirements. Be careful to prevent the danger of using fire.

Don't burn waste paper at will. When cleaning, litter and other garbage should be buried deep or sent to the garbage station, and the method of ignition and burning should not be used.

How to call the police in case of fire?

1. The telephone number of the fire alarm is 1 19. This figure should be kept in mind. In any part of the country, the telephone number for reporting fire to the public security fire department is the same.

If you find a fire, you can call the police directly. If you don't have a telephone at home, you should use the telephone of your neighbor, telephone booth or nearby unit as soon as possible. When reporting a fire alarm, it is necessary to explain to the fire department the unit or place where the fire broke out, the district (county), street, lane, house number or rural address, and also explain what the fire broke out and what the situation was.

3. After the alarm, it is best to arrange personnel to wait for the fire truck at the nearby intersection to guide the road to the fire.

4. Don't call the fire alarm at will. It is illegal to make a false report about the fire alarm, which disturbs public order.

5, in the absence of a telephone, should shout or take other methods to attract the attention of neighbors and pedestrians, to assist in fire fighting or alarm.

How to deal with a small fire in an emergency?

Teenagers should also master simple and easy methods to deal with sudden small fires.

1, water is the most commonly used fire extinguishing agent, and fires such as wood, paper and cotton cloth can be put out directly with water.

2. Quickly cover the fire with mud, sand, soaked quilts or blankets, which can effectively put out the fire.

3. Use a broom, mop, etc. , you can also put out small fires.

4, oil, alcohol and other fires, do not use water to fight, can be quickly covered with sand or soaked quilt.

5. When the gas is on fire, cover the fire source with a wet towel and quickly cut off the gas source.

6, electrical fire, don't put out the fire with water, also don't cover with wet items. Water is a conductor, so you will get an electric shock. The correct way is to cut off the power supply first and then put out the fire.

7, conditional, you can also learn how to use some simple fire extinguishers.

How to get out of the fire correctly?

In case of fire, correct and effective methods should be taken to save oneself and escape, so as to reduce the loss of personal injury and death:

1. Once threatened by fire, don't panic, calmly determine your position, and judge the fire according to the surrounding smoke, light and temperature, and don't act blindly.

2, in the bungalow, if the fire around the door is not big, should quickly leave the fire. On the other hand, you must choose another exit to escape (such as jumping out of the window) or take protective measures (such as soaking clothes with water, wrapping your head and upper body with warm quilts, etc.). ) before leaving the fire.

3. If you find a fire in a building, don't blindly open the doors and windows, otherwise it may lead to a fire. If you are in a building, don't run around blindly, let alone jump to escape, which will cause undue casualties. You can hide in the room or on the balcony.

4. Close the doors and windows, cut off the fire road and wait for rescue. Conditional, can continue to water the doors and windows to cool down, in order to delay the spread of the fire.

In the burning building, you should not use the elevator to escape, but take the stairs through the fire escape. Because the elevator shaft often becomes a channel for setting off fireworks after a fire. And the elevator may break down at any time.

6. Because the fire is too fierce, you must escape from the building. You can jump from the second floor, but you should choose a soft ground. At the same time, you should throw bedding upstairs to increase the buffer of the ground, and then slide down the window to minimize the falling height and let your feet land first.

7. If you are sure, you can tie one end of the rope (or tear the sheets together) to the window frame and then slide down the ground along the rope.

8. When you run away. Try to take protective measures, such as covering your nose and mouth with a wet towel and wrapping your body with wet clothes.

9. If clothes catch fire, you can take off your clothes quickly or roll around on the spot to put out the fire with your body. You can also jump into a nearby pool or river to put out the fire. In short, try to reduce the burn area of your body and reduce the degree of burn.

10, when a fire breaks out, it often produces gases that are toxic and harmful to human body, so to prevent smoke poisoning, you should try to stay in the windward or protect your mouth, nose and eyes with wet towels or masks to avoid the invasion of toxic and harmful smoke.

Three. Other disasters

Lightning protection measures: 1. In thunderstorm weather, people should try to stay indoors, don't go out, close doors and windows to prevent lightning from entering the room. 2.
