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, careless use of gas, careless smoking, playing with fire, setting off fireworks and firecrackers, etc.

4. Flammable items at home include: wooden furniture, bedding curtains, clothes, sofas, books, gas tanks, etc.

Second, 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 should be stored in a special warehouse and should be carried with you when used. Don't store them on site.

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

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

Third, common sense of forest fire prevention

1. When teachers and parents take their children out for an outing, 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.

Fourth, common sense of family fire prevention

1, use fire safely

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

(2) There should be protection around the furnace body or more than 0.5m away from combustible materials.

(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 and sprinklers for ignition.

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, wait for the fire, not the gas, and remember to turn off the valve and switch after use. If the valve is broken, it should be replaced in time. Don't let children use cookers or play with switches at will.

(3) When using liquefied gas, someone should be guarded, away from it, and adjust the rotor size at any time to prevent the soup from overflowing to douse the flame or being blown out by the wind, resulting in gas leakage.

(4) Liquefied gas tanks should be upright, not upside down, and cannot be cooked or baked with 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.

Five, the basic knowledge of fire fighting

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 fires:

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. Fires such as wood, paper and cotton cloth 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 a broom or mop.

(4) Oil, alcohol and other fires should not be put out with water, but can be quickly covered with sand or soaked quilts.

(5) In case of gas 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 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) If conditions permit, you can also learn how to use some simple fire extinguishers.

Six, alarm should pay attention to the following points.

1, indicating the district (county), street, township 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, to be clear, to the whole unit and street, lane name, don't use abbreviations.

3. Explain what substance is on fire and how big the fire is. 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 forces arrive, which is convenient for command and mobilization.

5, after the alarm, should be familiar with the situation to the nearest intersection to meet the fire truck or guide channel, provide water location, etc. , in order to quickly put out the fire.

Seven, middle school students take care of themselves, save themselves and escape common sense.

1, common sense of building fire escape

(1) Analyze calmly and don't act blindly. Be clear about your floor, remember the location and direction of stairs and doors; Analyze the surrounding fire, don't blindly open the window to open the door, otherwise it will add fuel to the fire, and don't blindly run and jump off the building, causing undue casualties.

(2) Choose an escape method and don't panic. If you must rush out of the building from fireworks, wrap your head and face, especially your mouth and nose, with wet towels, clothes and other clothes, and walk in a low posture to avoid suffocation. Although the building below is on fire, what is on fire? The potential is not great, just rush out of the stairs.

If the stairs are broken and can't be rushed out, they can be tied to solid doors and heavy objects with tiger windows, balconies, leaky pipes or ropes (which can be torn into ropes by clothes or bedding). The window slides down.

If you are forced to jump from the second or third floor without the above methods, you should also throw some quilts and other things at this position to increase the buffer, and then press the windowsill to reduce the falling height and ensure that your feet land. What about various escape routes? All were cut off by the fire, so we should retreat indoors and close the doors and windows. If possible, they can water the doors and windows to delay the spread of the fire, or throw small things out of the window and flashlights for help.

Don't use the elevator in the burning building.

In case of fire, don't take the elevator, because the elevator shaft goes straight to all floors of the building, and the smoke is very hot or easy to pour in. Because of stack effect, passengers can't bear the smoke and fire, and the elevator will be out of control or even deformed at high temperature. When putting out a fire, water easily flows into the elevator under the action of water stains, causing the danger of electric shock, and passengers are easily trapped inside, which is life-threatening.

If household appliances or gas stoves catch fire, turn off the power supply or the switch of the cooker quickly, and do not splash water on the appliances, wires or gas stoves.

3, personal fire self-help common sense

If you are on fire, don't run, or it will burn more and more brightly. You can try to take off your coat and hat, but you can tear it off and throw it away before it's too late. If it is too late, you can lie on the ground and roll, or jump into ponds, pools and rivers. If there are other people present, you can use wet sacks, blankets, etc. Put fire on people. Never spray a fire extinguisher directly on a burning person, because drugs can cause wound infection.
