Check three things, four skills and five firsts.

Four understandings:

1. Know the danger of post fire;

2. Know how to prevent fire;

3. Know how to put out the fire;

4. Know how to escape and evacuate.

Sihui:

1. Can use fire fighting equipment;

2. Will report the fire alarm;

3. Will put out the initial fire;

4. Will organize evacuation and escape.

2. What are the fire safety knowledge?

Learning content of fire safety knowledge in schools 1. The "four abilities" construction of school fire safety (1) checks the ability to eliminate fire hazards; (two) the ability to organize the fire fighting at the beginning; (3) the ability to organize personnel evacuation and escape; (four) the ability of fire education and training.

Second, the school fire safety knowledge 1, why should we educate students about safety? First of all, safety education for students is the need of the current fire situation and safety work, and it is a mass basic work to improve the fire prevention ability of the whole school. Secondly, carrying out student safety education is the need to protect the personal and property safety and legitimate rights and interests of students at school.

In the event of a fire, students at school are more vulnerable due to objective factors such as physiology and psychology. Third, students in school have an important position and unique role in school safety work.

60% to 70% of fires in schools occur in places where people are concentrated. Students are the masters of the school, and they play a very important role in preventing school fires.

If students' awareness of fire safety is weak and they lack common knowledge of fire fighting, their ability to put out initial fires and escape, self-help and mutual rescue is low. Once a fire breaks out, it will inevitably lead to a fire with serious consequences. Therefore, it is necessary to educate students on fire safety and improve their awareness of fire safety.

2. Why can't students and teachers use high-power appliances in their dormitories? First of all, student apartments belong to public accommodation and involve public safety interests. The use of high-power electrical appliances can easily lead to overload of wires, increase of current and heating of wires. The more you exceed, the faster the temperature rises. The allowable temperature of wire insulation is generally 60℃. If the line is overloaded for a long time, the calorific value of the line will increase and the insulation layer will accelerate aging.

When the temperature is higher than 250℃, the insulation layer will spontaneously ignite and separate from the wire, resulting in short circuit and fire accident. 3. which electrical appliances are not allowed to be used in the student dormitory? High-power electrical appliances such as electric stoves, rice cookers, electric heaters, electric blankets, electric cups, quick heating and air conditioners are strictly prohibited in student apartments.

4. Why can't you pull the wires around? First, people who don't know the electrician's professional knowledge are prone to fire accidents because of wrong wiring or weak connection, which leads to excessive contact resistance. Second, the design capacity of the conductor is limited, and the random connection of the conductor causes excessive load, which is easy to cause fire due to overload.

5. How to use "1 19" telephone or school alarm telephone correctly? First, be calm and don't panic when calling the police. Second, you should find out the fire unit, address, burning object and fire situation, and tell the fire brigade the name and telephone number of the alarm person for contact. After the alarm, I may send someone to meet the fire truck at the traffic intersection leading to the fire; Third, we should call the police as early as possible to gain time for fire fighting and reduce losses.

6. What are the causes of fire accidents? The main causes of fire accidents are: arson, electricity consumption, illegal operation, careless use of fire, playing with fire, smoking, spontaneous combustion, lightning strike, earthquake and wind disaster. 7. Why are there many fire accidents in winter? In winter, the weather is cold, the rain is scarce, and there are many kinds of raw materials stored, which consume a lot of fire, electricity and gas.

Winter is the beginning and end of every year. With busy production, short days and long nights, people tend to slack off and often ignore fire safety, so the first fire can't be found in time. Therefore, there are many fire accidents in winter, with great losses and casualties.

8. What is fire? A burning phenomenon that is out of control in time and space and causes certain harm is called a fire. 9. What are the basic principles of fire prevention? The basic principle of fire prevention is to prevent the generation of combustion conditions, prevent the combination and interaction of three combustion conditions, and take measures to limit and weaken the development of combustion conditions and prevent the spread of fire.

10, what are the basic measures for fire prevention? The basic measures of fire prevention are as follows: ① Control combustible substances. (2) Isolation of combustion-supporting materials.

③ Eliminate the ignition source. (4) Prevent the fire from spreading.

1 1. What are the basic methods of fire fighting? Cooling fire extinguishing method, isolation fire extinguishing method, suffocation fire extinguishing method and suppression fire extinguishing method. 12, what are the common fire extinguishers? Commonly used fire extinguishers are: dry powder fire extinguishers, carbon dioxide fire extinguishers and foam extinguisher.

13, how to use the carbon dioxide fire extinguisher How to use the carbon dioxide fire extinguisher: First pull out the safety bolt, then press the knob (or turn the valve) and aim the nozzle at the root of the flame to extinguish the fire. 14, the use of dry powder fire extinguishers? The dry powder fire extinguisher is used in the same way as the carbon dioxide fire extinguisher, but it should be noted that before using the dry powder fire extinguisher, the fire extinguisher should be turned upside down several times to loosen the dry powder in the steel cylinder.

When ABC dry powder fire extinguisher is used to put out solid fire, the fire extinguishing nozzle should be aimed at the most violent place, and the dry powder fire extinguisher should be sprayed on the surface of the burning object as evenly as possible until it is completely extinguished. Because the cooling effect of dry powder is very small, it is necessary to prevent re-ignition after fire extinguishing.

15. What are the causes of electrical fires? Electrical fires mainly include short circuit, overload, excessive contact resistance, electric leakage, improper use of electric heaters, static electricity, lightning and so on. 16, why should we pay attention to fire prevention when lighting mosquito-repellent incense? Mosquito-repellent incense has a strong smoldering ability, and there is no flame after ignition, but it can continue to burn for a long time.

When mosquito-repellent incense burns, the central temperature is as high as 700℃, which exceeds the ignition point of most combustible materials. Once exposed to flammable substances, it will cause combustion and even expand the disaster. 17, why should we pay attention to fire prevention when lighting with candles? Candle, as a movable fire source, may melt, flow or fall off carelessly, and it is also easy to cause fire when it meets combustible materials.

18, why do cigarette butts cause fires? The surface temperature of cigarette butts is 200? 300℃, the center temperature can reach 700? At 800℃, it exceeds the ignition point of combustible materials such as cotton, hemp, wool, paper and furniture. If cigarette butts come into contact with these combustibles, it is easy to cause burning or even fire. 19. Under what circumstances can smoking easily cause fire? (1) Smoking in bed and sofa.

② Smoking in places where smoking is prohibited. ③ When repairing cars and cleaning parts.

(4) throw unlit smoke spots and match stalks. 20. What should I do if the computer catches fire? The solution is: when the computer starts to smoke or catch fire, immediately unplug the power plug or turn off the main switch, and then cover the computer with a wet carpet or quilt, which can not only prevent the spread of fireworks, but also block the glass fragments on the screen.

Don't spill water on the burning computer, even if it is already on fire.

5. Middle school students' fire safety knowledge

Campus is a public place, with highly concentrated personnel, many teaching instruments, expensive scientific research equipment, large electricity consumption, various experiments and practice projects, and many flammable items. Once a fire accident happens, the impact and loss will be great, which will directly affect the normal teaching and scientific research work.

Therefore, our school has attached great importance to campus fire prevention for many years, and always put fire prevention work in the first place in all preventive work. Preventing campus fires is a long-term unremitting work, and learning fire fighting knowledge is an essential lesson for middle school students during their school study.

In order to enhance students' awareness of fire safety, clarify their responsibilities for fire safety and facilitate students to learn fire safety knowledge, we edited the book "Common Sense of Fire Safety for Middle School Students". The contents of this book mainly include: the basic knowledge of fire fighting, the basic knowledge of fire extinguishers, the first fire extinguishing method, the knowledge of personnel evacuation and fire escape, and the question and answer of fire fighting knowledge. , and collected campus fire cases, fire safety knowledge contest questions and so on.

Its purpose is to let middle school students know the common sense of fire safety, be familiar with the performance characteristics of fire fighting equipment, master the skills of fire fighting, evacuation and escape, improve their self-defense and self-help ability, and prevent campus fires. At the same time, it also provides learning and publicity materials for students and middle school students' volunteer fire brigades.

We hope that through the study of fire safety knowledge, the majority of students can achieve "three understandings and three skills", that is, they will understand the dangers of fires, fire extinguishing methods and fire prevention measures: they will report fires, use fire extinguishers and escape to save themselves. "Hidden dangers are more dangerous than open flames, prevention is better than disaster relief, and responsibility is more important than Mount Tai".

I hope that students will consciously assume the responsibilities and obligations of campus fire prevention, learn more about fire prevention, abide by various fire prevention systems, and actively participate in campus fire prevention, so that our school will form a situation of "everyone cares about fire prevention and pays attention to fire prevention everywhere" and fundamentally reduce or avoid the occurrence of campus fire accidents. (1) The definition of combustion, commonly known as fire, refers to the exothermic reaction between combustible substances and oxidants, usually accompanied by flame, luminescence and/or smoke.

Combustion has three characteristics, namely, chemical reaction, exotherm and luminescence. (II) Conditions of combustion Necessary conditions of combustion-The occurrence and development of the combustion process of substances must meet the following three necessary conditions, namely, combustible, oxidant and temperature (ignition source).

Only when these three conditions are met at the same time can combustion occur, and no matter which condition is lacking, combustion cannot occur. However, the above three conditions do not necessarily exist at the same time, and the combustion phenomenon will certainly occur. These three factors also need to interact.

1. Combustible: Any substance that can react with oxygen or other oxidants in the air is called combustible. Combustible substances can be divided into gas combustible substances, liquid combustible substances and solid combustible substances according to their physical states.

Combustible substances are mostly compounds containing carbon and hydrogen. Some metals such as magnesium, aluminum and calcium can also burn under certain conditions, and many substances such as hydrazine and ozone can release light and heat through their own explanation at high temperature. 2. Oxidant: A substance that helps and supports the combustion of combustible substances, that is, a substance that can undergo an oxidation reaction with combustible substances is called an oxidant.

The oxidant in the combustion process is mainly free oxygen in the air, and other oxidants such as fluorine and chlorine can also be used as oxidants in the combustion reaction. 3. Temperature (ignition source): refers to the energy source of combustion reaction between combustible substances and oxygen or combustion improver.

Common is heat energy, as well as other heat energy converted from chemical energy, electric energy and mechanical energy. 4. Chain reaction: There is a chain reaction in flame combustion.

When the fuel is heated, it will not only vaporize, but also the molecules of the fuel will decompose to produce free radicals. Free radical is a very active chemical form, which can react with other free radicals and molecules to keep the combustion going. This is a chain reaction of burning.

Sufficient conditions for combustion-(1) a certain combustible concentration; (2) certain oxygen content: (3) certain ignition energy; (4) Unrestricted chain reaction. For example, the minimum ignition energy of gasoline is 0.2raj, that of ether is 0. 19mJ, and that of methanol is 0.2 15mJ.

For flameless combustion, the first three conditions exist and interact at the same time, and combustion will occur. For flame combustion, in addition to the above three conditions, there are unrestrained free radicals (free radicals) in the combustion process, forming a chain reaction, which is also one of the sufficient conditions for combustion.

(III) Types of combustion Combustion is generally divided into four types according to its formation conditions and instantaneous characteristics: flash, fire, spontaneous combustion and explosion. Flash burning is a burning phenomenon in which a substance can flash when it meets fire.

Fire is a phenomenon that combustible substances contact with the fire source in the air, and when they reach a certain temperature, they start to burn with flames, and they can continue to burn after the fire source is removed. Spontaneous combustion is the combustion of combustible materials caused by heating or self-heating and heat accumulation without external sparks, flames and other fire sources.

Explosion is a phenomenon that the temperature and pressure rise or both rise due to the rapid oxidation or decomposition reaction of substances. Explosion can be divided into physical explosion, chemical explosion and nuclear explosion.

Physical explosion is an explosion caused by the rapid expansion of liquid or gas, and the pressure increases rapidly, which greatly exceeds the limit pressure of the container. Such as steam boilers; Liquefied gas cylinder explosion, etc.

Chemical explosion is an explosion caused by the chemical reaction of the substance itself, which produces a lot of gas and high temperature. Such as explosive explosion, explosion of combustible gas, liquid vapor, dust and air mixture, etc.

Chemical explosion is the key to prevent explosion in fire fighting. In addition to the direct contact of flame, heat usually spreads outward in three ways: heat conduction, heat radiation and heat convection.

(IV) Definition of fire A fire refers to a disaster caused by burning out of control in time or space. Fire is mostly a social phenomenon, and the main causes of fire can be summarized into three aspects.

One is man-made unsafe behavior (including arson); The second is the unsafe state of matter; The third is the defect of technology. And people's unsafe behavior is the most important factor.

(V) Classification of fires According to the combustion characteristics of substances, fires can be divided into five categories: A, B, C, D and E. Class A fires refer to solid material fires.

This kind of substance often has the nature of organic matter, and generally produces glowing embers when burning. Such as wood.

9. Fire protection knowledge

(1) Asphyxiation fire extinguishing method: it is a method of extinguishing fire by reducing the oxygen content in the air, which is suitable for extinguishing fires in relatively closed rooms and production facilities.

When the fire is extinguished by suffocation: ① Cover the combustible materials or close the holes with incombustible or nonflammable materials such as asbestos cloth, soaked quilt and canvas. (2) filling the combustion area with steam and inert gas.

(3) Use the original doors, windows on the building and spare parts on production, storage and transportation equipment to close the combustion zone to prevent fresh air from flowing in, so as to reduce the oxygen content in the combustion zone. It should be noted that the lid can only be opened when it is confirmed that the fire has been extinguished.

(2) Isolation fire extinguishing method: it is a fire extinguishing method that separates burning objects from nearby combustibles or evacuates combustibles to stop them from burning, and is suitable for all kinds of solid, liquid and gas fires. The specific measures are as follows: ① Transfer combustible, flammable and combustion-supporting substances near the fire source from the combustion area to a safe place.

② Close the valve to prevent gas and liquid from flowing into the combustion zone. ③ Eliminate combustible gas or liquid in production devices and equipment containers.

(4) Prevent the diffusion of flammable and combustible liquids and diffusion gases. ⑤ Dismantle the flammable building structure connected with the fire source to form a space zone to prevent the fire from spreading.

⑥ Block or explode with water flow to extinguish oil and gas blowout or forest fire. (3) Cooling fire extinguishing method: it is a fire extinguishing method that directly sprays fire extinguishing agent on burning objects to stop them from burning.

Usually dry fire extinguishing agent or wet fire extinguishing agent is used. When necessary, coolant can be used to cool building components to prevent building components from collapsing and injuring people.

(4) Suppression fire extinguishing method: it is a fire extinguishing method that makes the extinguishing agent participate in the combustion reaction, produces stable molecules or low-activity free radicals, and stops the combustion reaction. It should be noted that the fire extinguishing agent must be sprayed accurately in the combustion area.
