(1) Combustion must meet three conditions: combustible, combustion-supporting and fire source.

(2) Common fire sources are: open flame, high-temperature object, Mars, electric spark, strong light, etc.

(3) The fires caused by life factors mainly include: careless use of fire, careless use of electricity, careless use of oil and gas, careless smoking, playing with fire, setting off fireworks and firecrackers, etc.

(4) Household flammable items include: wooden furniture, bedding curtains, clothes, sofas, books, gas tanks, etc.

2. Fire prevention knowledge in schools and public places

(1) It is forbidden for students to bring fireworks, cannons, matches and other inflammable and explosive articles into the school.

(2) The inflammable and explosive articles used in the experiment shall be stored in a special warehouse, which shall be collected as needed, and shall not be stored at the site.

(3) Pay attention to regularly check the installation and use of electrical equipment, and cut off the power supply after use.

(4) Do not carry kindling and inflammable and explosive articles (such as gasoline and essence) to public places or take public transportation.

3. Common sense of forest fire prevention

(1) When teachers and parents take their children out for an outing, hunting, grazing and collecting herbs, don't bring kindling into the mountains. Smoking is not allowed in mountainous areas.

(2) When the school organizes students to travel to mountainous areas, it is forbidden to organize picnics, bonfire parties and other activities.

4. Common sense of family fire prevention

(1) Use fire safely.

(1) Chimneys should be far away from wires, ceilings, wooden walls, wooden doors and windows, etc. At least 0.2 meters apart.

(2) Around the furnace body should be protected or away from combustible materials for more than 0.5m..

(3) Don't dump ashes and slag, and don't touch flammable materials. It is best to have a fixed safe place, especially in windy days.

(4) Never use gasoline, diesel oil or essence to ignite.

(2) Safe use of liquefied petroleum gas

① LPG cookers should not be placed in bedrooms, offices, balconies, warehouses, auditoriums and other public places to prevent air leakage and fire.

(2) Correctly master the use of the switch, be gentle and not angry, remember to turn off the valve and switch after use, and replace the valve in time if it is broken. Don't let children use cookers or play with switches at will.

(3) When using liquefied gas, someone should take care of it and stay away from it. Pay attention to adjust the size of the rotor at any time to prevent the soup from overflowing and extinguishing the flame or being blown out by the wind, resulting in air leakage.

(4) Liquefied gas tanks should be upright, not upside down, let alone boiled water or fire.

⑤ If there is air leakage, measures should be taken immediately: open doors and windows, ventilate with a fan (but not an electric fan), and then find the leaking part.

5. Basic knowledge of fire control

(1) isolation method: This is a method to eliminate combustible materials.

(2) Asphyxiation method: prevent air from flowing into the combustion zone, reduce the oxygen content in the air, and make the fire source go out under the condition of insufficient oxygen.

(3) cooling method: spray water or other fire extinguishing agents on the combustible materials to lower the temperature of the combustible materials below the ignition point and force the combustion of the materials to stop; Or spray water and fire extinguishing agent to combustible materials near the fire source to reduce the temperature of combustible materials and avoid the expansion of the fire.

(4) Emergency measures for minor fire:

If there is a fire, you should call the police in time. Students should also master simple and easy methods to deal with sudden small fires.

(1) Water is the most commonly used fire extinguishing agent. For example, when wood, paper and cotton cloth catch fire, it can be put out directly with water.

(2) quickly covering the fire with mud, sand, soaked quilts or blankets can effectively extinguish the fire.

(3) Small fires can also be put out with brooms and mops.

(4) Don't put out fires such as oil and alcohol with water, but quickly cover them with sand or soaked quilts.

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

⑥ When the electrical appliance is on fire, don't put it out with water or cover it with damp articles. 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 If conditions permit, you can also learn how to use some simple fire extinguishers.

6, alarm common sense

In case of fire, call "1 19" to give an alarm to the fire brigade, and immediately organize personnel to put out the fire. When fighting, save people first, then save people, focus first, then put out the fire, and pay attention to disaster relief with the wind, especially in the field fire. When putting out a fire, generally use local materials, such as water, sand, soil and other fire extinguishing equipment, especially try to control the spread of the fire. It is strictly forbidden to mobilize and organize primary and secondary school students to participate in forest fire fighting. At the same time, it is necessary to strengthen the education and management of primary and secondary school students who are not allowed to participate in forest fire fighting. In case of spontaneous forest fire fighting, schools and relevant departments should dissuade them in time to prevent unnecessary casualties.

Attention should be paid to the following points when alarming:

(1) Indicate the district (county), street, town or village where the fire unit or household is located. When there are duplicate names, distinguish them so as not to find the wrong one. There are similar or confusing words in place names or unit names, which should be emphasized and clarified.

(2) You must quote the names of all units and streets, and do not use abbreviations.

(3) Explain what substance is on fire and the size of the fire. This is convenient for the fire brigade to decide the vehicles and police force it dispatched according to the burning object and the size of the fire.

(4) explain the name and telephone number of the alarm person. Because the telephone used by the alarm person is often close to the fire site, the fire brigade can use this telephone to ask the alarm person about the development of the fire site before the dispatched force arrives, which is convenient for command and mobilization.

(5) After the alarm, people familiar with the situation should go to the nearest intersection to meet the fire truck or guide the passage, and provide the location of water source so as to quickly put out the fire.
