What are the common sense of children's fire fighting?
1. Children's fire protection knowledge

Children's fire knowledge 1. Primary school students' fire safety knowledge (abbreviated)

1. Students are not allowed to play with fire or carry kindling with them: 1. No kindling such as matches or lighters; 2. Do not ignite at will, and do not use fire in inflammable and explosive articles; 3. It is not allowed to set off firecrackers in public places and throw lit firecrackers around.

Second, at the scene of the fire, minors such as primary school students should escape in an orderly manner: 1. If there is a refuge floor or evacuation stairs, you can enter the refuge floor first or evacuate to a safe place through the evacuation stairs. 2. If the floor is on fire, but the stairs have not been burnt out and the fire is not very fierce, you can put on a clothes soaked with water and rush down from the upstairs quickly.

3, multi-storey building fire, such as the stairs have been burned out, or the fire has been quite fierce, you can use the balcony, downspout or bamboo poles to escape. If all escape routes are cut off, you should retreat indoors and close the doors and windows.

If conditions permit, water can be poured on doors and windows to delay the spread of fire. At the same time, you can throw small things outdoors and send out a distress signal with a flashlight at night.

5, if life is seriously threatened, and there is no other way to save yourself, you can use rope or sheets to tear into strips and connect them, one end of which is tightly tied to a solid door and window lattice or other heavy objects, and then slide down along the rope or cloth. 6. If the above-mentioned self-rescue measures are taken unconditionally, and the time is tight and the threat of fireworks is serious, when you are forced to jump off a building, you can throw some quilts and other things on the ground to increase the buffer, and then slide down with your hands on the windowsill to reduce the jumping height and ensure that your feet land first.

7. To carry forward the spirit of mutual assistance, first help the elderly, children and patients to evacuate. People with mobility difficulties can use quilts, blankets and other packages. , and hung down with a rope.

Third, the fire prevention of student dormitories. The fire safety of student dormitory should be ten (1). Do not pull the wire without permission; (2) Smoking and littering cigarette butts are not allowed in bed; (3) It is forbidden to occupy or block evacuation passages; (4) Don't burn sundries in the building; (5) Don't bring inflammable and explosive articles into the house; (6) Electric heating equipment such as "quick heating" is not allowed; (7) It is forbidden to use open flame appliances such as alcohol stoves; (8) Do not change the power supply equipment without authorization (9) Do not leave the dormitory without turning off the power supply; (10) Don't damage fire extinguishers and fire-fighting facilities. Fourth, what should I do when I first find a fire? If you find a fire, you should shout loudly or knock on something that can make a sound, such as washbasin and aluminum pot, to call more people to participate in the fire fighting, and call "1 19" to call the fire department quickly.

When dialing "1 19", please pay attention to the following details: 1, "1 19" fire alarm telephone (it is best to use a fixed telephone), be calm and calm, and dial the number1/kloc after hearing the dial tone. 2. After the telephone is connected, the address of the fire (including road name, street name, lane name and house number) should be explained clearly.

3, as far as possible, explain what is the fire and fire scope, and the number of people trapped. 4. Quietly answer the questions of the communication staff of the "ll9" main console.

5, after the phone hang up, should send someone to meet the fire truck at the intersection. Five, three elements of fire fighting 1, downwind fire fighting, in case of being burned by fire.

2, the root fire, the effect is the most thorough. 3, 2-3 meters from the root, the best distance.

The effective distance of the fire extinguisher is only 4.5 meters. Six, the use of portable dry powder fire extinguisher 1, put the fire extinguisher on the ground, hold the bottleneck with your left hand, hook the safety pin with your right index finger, and gently pull it.

Don't hold the handle hard with your left hand. 2. Pick up the cylinder, hold the bottom of the cylinder with your left hand and squeeze the handle with your right hand.

3, when the fire cylinder should be tilted down 45 degrees. 4. The pointer of the cylinder pressure gauge points to the red * * * field, indicating that the fire extinguisher is invalid, and those pointing to the yellow and green * * * fields can be used normally.

7. What material fires can't be put out by water? 1, alkali metals cannot be extinguished with water. Because water reacts with alkali metals (such as potassium and sodium), it can decompose water to produce hydrogen and release a lot of heat, which is easy to cause explosion.

2. Residual alkali metal carbides and alkali metal hydrides cannot be extinguished by water, such as potassium carbide, sodium carbide, aluminum carbide and calcium carbide. Potassium hydride and magnesium chloride react with water, releasing a lot of heat, which may cause fire and explosion. 3. Flammable liquids that are lighter than water and insoluble in water shall not be extinguished with water in principle.

4. Hot metal and molten steel cannot be put out with water. Because the temperature of molten steel is about 1600℃, water vapor can decompose hydrogen and oxygen above 1000℃, which may cause explosion.

5, three acids (sulfuric acid, nitric acid, hydrochloric acid) can't use concentrated water, spray water can be used when necessary. 6, high voltage electrical equipment is on fire, in the absence of good equipment grounding or without cutting off the current, generally can't use water to put out the fire.

Eight, the fire should follow the 1, smoke prevention "three rescues" principle. Cover your nose and mouth with a wet towel for 3-8 layers (only 3-5 minutes). If there are no conditions, you can sprinkle urine on your clothes to prevent smoking.

2. Grasp the direction and escape. When a fire breaks out, it is the best choice to use stairs, evacuation passages and open stairs with weak smoke or unburned fire to escape.

But when the environment is opaque or unfamiliar, get up from the ground to find the wall, follow the wall to find the door (clockwise or counterclockwise) and escape from the door. 3. Use tools to escape. For fires below the third floor, use ropes in time (or tear windows and sheets into long strips), and tie them firmly to objects that can bear loads, such as water pipes or heating pipes. The other end hangs from the window to the ground or the lower balcony, and then slide down along the ropes to escape from the fire.

Fire on the 4th-6th floors can be escaped with fire hydrants. Nine, the specific content of the "72-word formula" for fire escape is familiar with the environment and easy to find the exit; If a fire is found, call the police early; Stay calm and flee in an orderly manner; Simple protection, prostrate and bend; Carefully enter the elevator and transfer to the corridor; Slow down and escape, not wait to rely on; The fire has burned you, don't run; It is better to stick to it if you are trapped indoors; Escape from a dangerous place, neither greedy nor noisy.

3. How to teach children fire safety knowledge

Method 1: Play games.

It is children's nature to love to play and play games, and it is often unexpected to incorporate some fire prevention knowledge into the game. Parents can practice escape with their children, teach them how to bend over, how to cover their nose and mouth with wet towels, and simulate a fire with their children (remember not to dial "1 19" directly. )

The second method is to tell children stories and recite children's songs. With the popularization of the Fire Protection Law and other laws and regulations, the society attaches great importance to fire protection work, and there are more and more popular books and comic pictures on fire protection for children in the market. Parents and friends can read more books on this subject, master some materials and teach them by telling stories and singing children's songs. Literate children can take them directly to study, not only to teach children to read and read, but also to teach children fire prevention knowledge, killing two birds with one stone.

Method 3: Active mobilization method. Every child has a strong psychology and likes adults to praise them for being good and smart. For some knowledge that needs to be memorized, such as the home address and telephone number that must be clearly stated when dialing "1 19", you can compete with your children to see who can recite quickly and remember well, and sometimes you can pretend that you have lost, so as to arouse their enthusiasm.

There are many ways for children to learn. Here are just a few of them. In the process of educating children, parents and friends can choose one or more of them according to the situation, or they can try new methods themselves, but the key is to let children really learn fire protection knowledge. There is also a catchy ballad here, which allows you to learn fire fighting knowledge while playing with your children.

Fire songs & songs that hit the fire and run away, don't be greedy for things and bags; Usually master the escape method and be familiar with the route. If you are threatened by getting wet, you should find a safe exit; It is most important to cover your nose with a wet towel through the thick smoke sticking to the ground.

Don't run when there is a fire, roll on the spot to suppress the flame; In case of fire, abandon the ladder and escape to the emergency exit. The outdoor fire door is hot and you can't escape by it; In order to prevent the fire from entering the room, soak the bedding and block the door.

If the escape route is blocked, return to the room to send a signal; Waiting for rescue is the key, and firefighters are highly skilled.

5. What fire safety knowledge do children have?

Life is a long road, and fire and fire have been together for five thousand years. Send warm is the condition that accidentally caused the fire. Three combustible oxygen combustion-supporting ignition sources are closely connected. The fire of three to one goes out automatically. There are four fire extinguishing methods: one point one cooling, two isolation, three suffocation and four suppression. It is not foolhardy to study and practice often. Who is in charge of the fire protection system? Who is responsible for the implementation of the fire prevention system? Familiar with fire fighting methods. When you call 1 1 9, you must make it clear where, what and where the fire is hung, so that you can meet a police car intersection. The fire brigade doesn't charge money. People familiar with the matter said in time that the situation at the scene of the fire was changing. First, control the emergency of rescuers, and then generally want to give children daily safety education. Don't throw cigarette butts, don't make a fire casually, and don't throw materials for decorating houses. No fire, no fire, no occupation, no buried fire hydrant, no dangerous goods, strictly control and restrict public places, keep an eye on fire signs, how to avoid disasters, don't panic, fire lanes should be unblocked, fire hazards should be clearly seen, everyone should take good care of fire in life, dangerous goods should not be near, gas leakage valves should be closed, doors and windows should be banned, heating wires should be repaired, and fuses should be replaced with special copper and iron. Don't use electric fire to quickly evacuate money, goods and wealth. Don't wear wet clothes, cover your nose and mouth with smoke, stick to the ground, catch fire, turn over thick clothes, hold back the fire, close the door to escape, and hide cold water in the gap between bedding. Always remember to keep in mind the benefits of being alive, and don't scratch the fire to keep you safe.

6. Pupils are in urgent need of fire safety knowledge.

Primary school students' fire safety knowledge on how to prevent fire 1, lit candles and mosquito-repellent incense should be placed on special shelves, away from curtains, mosquito nets and other flammable items.

2. When looking for things under the bed and in the attic, don't use open flames such as oil lamps, candles and lighters for lighting. 3. Primary and secondary school students are not allowed to carry matches, lighters and other kindling with them.

4, can't disorderly pull, disorderly pull wires, electrical appliances, unplug the bolt in time after using electrical appliances. 5, found that the gas leakage, to close the valve, open the doors and windows, don't touch the electrical switch and use open flame.

6, balcony, corridor can't burn paper, fireworks. 7. Smoking is harmful to health. Students should not smoke. It's more dangerous to hide and smoke.

8. When using electric lights, don't touch or get close to flammable materials. Classification of fire extinguishers There are many kinds of fire extinguishers, which can be divided into portable and cart-type according to their moving modes. According to the power source driving the fire extinguishing agent, it can be divided into gas cylinder type, pressure storage type and chemical reaction type, and according to the filled fire extinguishing agent, it can be divided into foam, dry powder, haloalkane, carbon dioxide, acid and alkali, clear water and so on.

Adaptability and usage of fire extinguisher (portable) foam extinguisher Adaptability and usage Scope of application: It is suitable for fighting general Class B fires, such as oil and grease fires, and can also be used for fighting Class A fires, but it cannot fight water-soluble flammable and combustible liquids, such as alcohols, esters, ethers, ketones and other substances in Class B fires; It is also impossible to put out live equipment and class C and D fires. Usage: You can carry the lifting ring on the top of the bucket and go to the fire quickly.

At this time, care should be taken not to tilt the fire extinguisher excessively, nor to hold it horizontally or upside down, so as to avoid mixing the two chemicals and spraying it in advance. When the distance from the ignition point is about 10 meter, the cylinder can be turned upside down, with one hand holding the bail tightly and the other hand holding the cylinder bottom ring, aiming the jet at the combustion products.

When putting out flammable liquid fire, if it is already flowing and burning, spray foam from far and near to make the foam completely cover the burning liquid surface; If burning in a container, the foam should be shot at the inner wall of the container, so that the foam can flow along the inner wall and gradually cover the fire surface. It is strictly forbidden to spray directly on the liquid surface, so as to avoid the burning liquid from being scattered or rushing out of the container due to the impact of the jet, and expand the combustion range.

When putting out the fire of solid matter, the jet should be aimed at the place where the fire burns most violently. When putting out a fire, with the shortening of the effective spraying distance, users should gradually approach the burning area and always spray foam on the burning object until it is extinguished.

When in use, the fire extinguisher should always be turned upside down, otherwise the spraying will be interrupted. (Portable) foam extinguisher should be stored in a dry, cool, ventilated and convenient place, not near high temperature or places that may be exposed to sunlight to prevent carbonic acid from decomposing and failing; Anti-freezing measures should be taken in winter to prevent freezing; And should always wipe the dust, dredge the nozzle, keep unobstructed.

Cart-type foam extinguisher is suitable for fire, and the use method is the same as that of portable chemical foam extinguisher. Usage: When using, it is usually operated by two people. First push and pull the fire extinguisher to the fire point quickly, and stop at a place about 10 meters away from the fire point. After one person applies the spray hose, hold the spray gun tightly with both hands and aim at the burning place. The other is to turn the handwheel counterclockwise, so that the screw rises to the highest position, so that the bottle cap is completely opened, and then pour the steel bottle backwards, so that the pull rod touches the ground, rotate the valve handle 90 degrees, and spray foam to extinguish the fire.

If the valve is installed at the spray gun, the person in charge of operating the spray gun will open the valve. The fire extinguishing methods and precautions are basically the same as those of portable chemical foam extinguisher, which can be used for reference.

This kind of fire extinguisher can give full play to its advantages because of its long spraying distance and long continuous spraying time, and can be used to extinguish the initial fire of large-area storage tanks or tankers. Adaptability and scope of application of air foam extinguisher to fire: the scope of application is basically the same as that of chemical foam extinguisher.

However, solvent-resistant foam extinguisher can also extinguish the fire of water-soluble flammable liquids, such as the initial fire of burning solvents such as alcohol, ether and ketone. Usage: When in use, you can quickly rush to the fire site with your hands or shoulders. When it is about 6 meters away from the combustible, pull out the safety pin, hold the opening handle in one hand and the spray gun in the other; Squeeze the opening handle hard, open the seal or puncture the seal of the gas cylinder, and the air foam can be ejected from the nozzle of the spray gun.

The fire extinguishing method is the same as that of portable chemical foam extinguisher. However, when using the air foam extinguisher, the fire extinguisher should always be in an upright position, and it should not be used upside down or horizontally, otherwise the spraying will be interrupted.

At the same time, always hold the open handle tightly, and don't let go, otherwise the injection will be interrupted. Adaptability and scope of application of acid-base fire extinguisher to fire: it is suitable for putting out the initial fire of class A substances, such as wood, fabric, paper and other fires.

It cannot be used to put out fires caused by the burning of Class B substances, nor can it be used to put out fires caused by Class C combustible gases or Class D light metals. At the same time, it cannot be used to put out the fire of charged objects.

Usage: When using, you should lift the ring on the upper part of the steel cylinder and rush to the fire site quickly. Never put the fire extinguisher on your back, and don't tilt it too much to prevent the two liquids from mixing and spraying in advance.

When it is about 6 meters away from combustible materials, the fire extinguisher can be reversed and shaken several times to speed up the mixing of the two liquids; Hold the lifting ring with one hand and the bottom ring under the cylinder with the other hand, and aim the jet at the place where the combustion is the fiercest. At the same time, with the decrease of injection distance, users should push closer to the burning place.

How to put out a fire with a carbon dioxide fire extinguisher? Just lift or carry the fire extinguisher to the fire site. Put down the fire extinguisher and pull out the safety pin when it is about 5 meters away from the combustibles. Hold the handle at the root of the horn with one hand and the pressure handle of the switch valve with the other hand. For carbon dioxide fire extinguishers without water hose, the horn should be at 70-90 degrees with the upper plate.

When using, you can't directly grasp the outer wall of the horn or the metal connecting pipe with your hands to prevent your hands from being frostbitten. When putting out fire, when combustible liquid burns in a flowing state, the user sprays the jet of carbon dioxide extinguishing agent from near and far to the flame.

If combustible liquid burns in the container, the user should raise the horn. Spray into the combustion container from the upper part of one side of the container.

However, the carbon dioxide jet can not directly impact the surface of combustible liquid, which prevents combustible liquid from being washed out of the container, expands the fire and brings difficulties to fire fighting. Cart-type carbon dioxide fire extinguishers are generally operated and used by two people.
