Fire prevention knowledge, short for junior high school, 200 words, thank you

Electrical appliances:

1. The TV should be kept at a certain distance from the wall to facilitate ventilation and heat dissipation. Do not turn it on when no one is in the room. Turn it off immediately after use and unplug it.

2. When using an electric iron to iron clothes, place the iron on a fire-resistant brick, slate, or iron stand. Do not leave the power on unattended, and unplug it promptly after use.

3. The refrigerator should be kept at a certain distance from the wall and objects on both sides to facilitate ventilation and heat dissipation. Because dust and lint accumulated on motors, compressors, fans and coils are the main causes of fires, pay attention to keeping the refrigerator clean.

4. The power of incandescent bulbs is different, and their surface temperatures are also different under general heat dissipation conditions after being powered on. For example, the surface temperature of 40-watt is 50-63℃, 60-watt is 137-180℃, and 100-watt is 170-216℃. The ignition point of general combustibles is within this temperature range. Therefore, when using incandescent bulbs, you must keep a certain distance from combustible materials. Do not use light bulbs to bake clothes, towels, etc. Don't use paper to make your own lampshade. If the paper is burned and ignited, it will cause a fire.

5. Do not extend the wires of electrical equipment casually. Be especially careful not to run wires under furniture and carpets to prevent short circuits and fires caused by moving furniture or people stepping on them.

6. The weather is cold in winter. When using infrared and other equipment, students should be careful not to put flammable or flammable objects close to the heater to avoid causing a fire.

Details of using mosquito coils:

1. Mosquito coils should be placed on the bracket. Do not place the stand on a cardboard table or wooden floor. It is much safer if placed on metal plates, porcelain plates, cement floors, and brick floors.

2. Do not put mosquito coils on windowsills or other places that are easily blown by the wind.

3. When using electric mosquito coils, place them on the ground away from flammable materials such as paper and wooden tables. When not in use, the latch should be unplugged.

Kitchen:

1. Whether using pipeline gas, natural gas, or canned liquefied petroleum gas, the operating procedure of "ignite first, then supply gas" must be followed. Otherwise, the flammable gas will mix with air to form an explosive gas mixture. When you ignite it, it is very likely to explode and cause a fire. After use, close the valve.

2. Young children should not use liquefied petroleum gas. When older children first learn to light a gas stove, they should follow the instructions of adults. After lighting, remember to place the matches away from the fire source and do not leave them on the stove to prevent fires.

When boiling water, the overflowing water will extinguish the fire, causing gas leakage and causing a fire. Therefore, when the fire is extinguished by overflowing water, the air source should be turned off immediately and doors and windows should be opened for ventilation.

3. When using gas to boil water for cooking, don’t just play for fun, but pay special attention. Adjust the air volume at any time to prevent the soup from overflowing and extinguishing the flame or the wind blowing out the flame, causing air leakage and danger.

Others:

1. Do not carry matches, lighters or other tinder on your body; do not carry any flammable and explosive materials.

2. When going out for picnics, be sure to choose a sand stall or an open and safe place under the leadership of a teacher or counselor.

3. Picnics should be stopped in windy weather. After the picnic, be sure to extinguish the fire to prevent "resurgence" of forest fires.

Fire self-rescue:

All means of fire extinguishing basically focus on destroying any of the three conditions that cause combustion (combustibles, combustion-supporting materials, ignition energy). The basic methods are:

(1) Isolation method; (2) Cooling method; (3) Suffocation method; (4) Chemical interruption method.

Commonly used fire extinguishing methods: (1) Use water to extinguish fire; (2) Sand to extinguish fire; (3) Fire extinguisher.

Common sense about fire escape. In a fire, fire is not the most dangerous enemy. Smoke and panic are the main causes of death. For example, the fire in Zhongbai Commercial Building in Jilin City on February 15, 2004. 54 people died, 4 of whom jumped from buildings and fell to death. Most were suffocated by thick smoke. More than 70 people were injured, 14 of whom were seriously injured. Some of them were seriously injured after jumping from buildings and falling. When a fire occurs, you must be calm and make correct judgments:

(1) Residents living in high-rise buildings or guests staying in high-rise hotels should understand and be familiar with the building’s emergency doors and safety measures in advance Be prepared when exporting, just in case.

(2) When heavy smoke occurs, you should leave quickly. When the smoke has entered the room, you should crawl along the ground. Because there is more fresh air on the ground floor, it is not easy to be poisoned and suffocated, which is conducive to escape. When you arrive at the door, never stand to open it to avoid being overwhelmed by the heavy smoke.

(3) When escaping to the outdoor corridor, try to close the door immediately. If there is a fire door, close it immediately. This can prevent the fire from spreading rapidly with the movement of people and increase the effective time of escape.

(4) Never take the elevator when escaping, because after a fire, the elevator may lose power or lose control. At the same time, due to the "chimney effect", the elevator often becomes a flow channel for thick smoke.

(5) If there is thick smoke coming out of the lower stairs, do not forcefully escape down, because the source of the fire may be on the lower floor. It is more reliable to escape upward. You can go to the balcony or rooftop to find a safe place to wait. Opportunity awaiting rescue.

(6) If you are trapped indoors, you should quickly open the faucet, fill all water containers with water, and wet your towels, sheets, and blankets for ready use.

Cover your mouth with a wet hand towel. Three layers of wet hand towels can cover 30% of the smoke from being inhaled. Twelve layers of wet hand towels can cover 90% of the smoke. However, wet hand towels can also easily cause suffocation. , the water content cannot exceed three times its own weight.

That’s about it, LZ can refer to it~
