The flammability of common combustibles, such as cotton, linen, paper, and furniture, is only around 200°C to 300°C. The temperature of lit cigarettes is two or three times higher than the ignition temperature of these combustibles, and the burning of one cigarette continues. The time is about 10 to 20 minutes, causing a long time for fire insurance. Therefore, we must warn the comrades of smoking:

Fire extinguishing with water.

★ Electrical fire:

When a household appliance or a line is on fire, it is necessary to cut off the power supply first, and then use a dry powder or gas fire extinguisher to extinguish the fire. It is not possible to splash water directly to prevent electric shock or electrical explosion.

★ TV set fire:

If the TV is to be fired together, it must not be poured with water. After the power is turned off, it is covered with a quilt. When the fire is extinguished, the television must only be approached from the side to prevent the explosion of the picture tube. If a fire extinguisher is used to extinguish a fire, it should not be shot directly on the TV screen to avoid sudden explosion and explosion when it is heated.

★ Pan fire:

When the oil pan fires, the gas valve of the stove should be quickly closed, and the pan lid should be directly covered or covered with a wet rag.

Family sets fire to use towels:
Towels are necessary for daily life. They not only have a face to wash, but also can be used to decontaminate. When a fire is encountered, they can be used to extinguish fires and save themselves. Especially for the coming of the festive season, dangers are lurking behind the celebration. Pay attention to fire safety and learn more about fire fighting. Common sense and more self-rescuing instincts can effectively protect themselves in the face of dangerous situations.
1, gas leak alarm : When using gas or liquefied petroleum gas, if a wet towel is standing nearby, in the event of a gas leak from the gas or liquefied gas pipeline, use a wet towel to cover it and close the valve immediately to avoid a fire. .
2. If the building is in a fire and the person is trapped in the room and the smoke is filled, the towel can be used as a gas mask for a while. Tests have shown that the more folded layers of towels, the greater the smoke removal effect. In an emergency situation, folding an 8-layer towel can achieve a smoke removal rate of 60%.
3. The wet towel is better than the dry towel in eliminating smoke and eliminating the irritating substances in the smoke, but its ventilation resistance is larger than the dry towel.
4, for the texture of the towel is not dense as much as possible to increase the number of folds. At the same time, it is better for self-rescue if you want to cover your mouth and nose so that the area of ​​protection is greater.
5, in the smoke can not take the towel from the mouth and nose, even if only inhaled, it will make breathing difficult. It should be noted that using a towel does not eliminate carbon monoxide.
6. The high-rise buildings are all reinforced concrete structures. Due to the interior decoration of the home, the interior is covered with chemical fiber carpets or plastic floors, plastic wallpaper on the walls, sponge sofas and mattresses, plastic shade shutters and some chemical raw materials. Furniture and supplies are flammable. When a fire breaks out, it produces a lot of smoke and it is easy to suffocate. Therefore, taking refuge in heavy smoke and covering your mouth and nose with a towel can make you better manage to save yourself.

In addition, when a high-rise building catches fire, people are trapped in the building. Towels may also be hung out of the window as a distress signal to get help from firefighters.
