Primary school students'fire safety knowledge Basic Knowledge 2. Common Knowledge of Fire Prevention in Schools and Public Places 3. Common Knowledge of Fire Prevention in Mountain Forest   1.Combustion must have three conditions: combustibles, combustion aids and sources of fire.2. Common sources of fire are: open fire, high temperature objects, Mars, sparks, strong light, etc.3. Fires caused by factors in life 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, etc.4. Flammable household items include: wooden furniture, bedding curtains, clothing, sofas, books, gas cans and so on. 1. Students are prohibited from carrying inflammable and explosive items such as fireworks, firecrackers, matches and so on.2. The inflammable and explosive articles used in the experiment should be stored in a special warehouse. They should be kept on the spot.3. Pay attention to check the installation and use of electrical equipment frequently, and cut off the power supply after use.4. Do not carry flammable and explosive materials (such as gasoline, sprinkler, etc.) to public places, or take public transport.1. Teachers and parents take their children outing, hunting, grazing. Do not bring fire into the mountains when collecting medicine, let alone smoke in the mountains and forests.2. When the school organizes students to travel to mountain and forest areas, it is strictly forbidden to organize picnics, campfires and other activities. 4. Common Knowledge of Family Fire Prevention 5. Basic Knowledge of Fire Extinguishing 6. Common Knowledge of Alarm   1.Safe use of fires (1) Chimneys should be away from wires, roofs, wooden walls, doors and windows, at least 0.2 meters apart.(2) There should be protection around the furnace body or more than 0.5 meters away from combustibles.(3) Clean up the ash. Don't pour the slag in disorder. Don't touch the combustibles. It's better to have a fixed safe place. More attention should be paid to blowing down the ash.(4) Never ignite a fire with gasoline, diesel or sprinkler.2. Safe use of LPG (1) LPG stoves should not be placed in public places such as bedrooms, offices, balconies or warehouses, auditoriums, in order to prevent leakage and fire.(2) Correctly grasp the use of switches, such as fire and gas, do not wait for fire, with the valve closed by all means. Switch, the valve should be replaced in time when it is broken.Do not let children use cookers or play with switches at will.(3) When using liquefied petroleum gas, someone should take care of it and keep it away from it. The size of the fire head should be adjusted at any time to prevent the water from overflowing and extinguishing the flame or being blown out by the wind and causing the exhaust gas.(4) Liquefied gas tanks should be upright, not upside down, not to mention boiling bubbles or roasting.(5) If air leakage is found, measures should be taken immediately: open doors and windows, fan to incite, so as to ventilate (but not blow by electric fan), and then find the leakage site.1. Isolation: This is a method of eliminating combustibles.2. Asphyxiation method: to prevent air from flowing into the combustion zone, reduce the oxygen content in the air, so that the fire source can not get enough oxygen and extinguish.3. Cooling method: water or other fire extinguishers are sprayed on the combustibles to reduce the temperature of the combustibles below the ignition point, forcing the combustion of the materials to stop; or water and fire extinguishers are sprayed on the combustibles near the source of the fire to reduce the temperature of the combustibles and avoid the expansion of the fire.4. Emergency measures for minor fires: If a fire occurs, the alarm should be given in time.Students should also master simple and easy ways to deal with emergencies when a relatively minor fire suddenly occurs.(1) Water is the most commonly used fire extinguishing agent, wood, paper, cotton cloth and other fire, can be directly extinguished with water.(2) Soil, sand, wet quilt or blanket can be quickly covered in the fire site, which can effectively extinguish the fire.(3) Smaller fires can also be extinguished by beating with brooms, mops, etc.(4) Oil, alcohol and other fire, not water to fight, can be quickly covered with sand or wet cotton quilt.(5) Gas fire can be covered with a wet towel to quickly cut off
