1, the TV should keep a certain distance from the wall to facilitate ventilation and heat dissipation. Don't drive when there is no one indoors. Turn off the machine in time after use, and unplug the bolt.

2. Iron clothes with an electric iron. Put the iron on the firebrick, slate and iron bracket. Don't turn on the power supply when unattended, and unplug the bolt in time after use.

3. The refrigerator should keep a certain distance from the wall and objects on both sides to facilitate ventilation and heat dissipation. Because the dust and lint accumulated on the motor, compressor, fan and coil are the main causes of fire, we should pay attention to keeping the refrigerator clean.

4. The surface temperature of incandescent bulbs is different under general heat dissipation conditions after being electrified. For example, the surface temperature of 40 watts is 50-63℃, that of 60 watts is 137- 180℃ and that of 100 watts is 170-2 16℃. Generally, the ignition point of combustible materials is within this temperature range. Therefore, the use of incandescent bulbs must keep a certain distance from flammable materials. Don't bake clothes, towels and other things with light bulbs. And don't use paper as a lampshade. If the paper burns and ignites, it will cause a fire.

5. Don't extend the wires of electrical equipment at will. Pay special attention not to pull wires under furniture and carpets to prevent moving furniture or people from stepping on it and causing short circuits.

6. In summer nights, mosquitoes often make it difficult for people to fall asleep, and people often use mosquito-repellent incense to repel mosquitoes. Although mosquito-repellent incense is small, it is easy to cause fire if used improperly, so be sure to check it before going to bed.

(1) mosquito-repellent incense should be placed on the bracket. Do not put the bracket on the carton desktop or wooden floor. It is much safer if it is placed on metal plates, porcelain plates, cement floors and brick floors.

(2) Don't put mosquito-repellent incense in places that are easily blown by the wind, such as window sills.

(3) When using electric mosquito-repellent incense, it should be placed on the ground far away from flammable items such as paper and wooden tables. Unplug the bolt when not in use.

7. No matter in town or country, many families can't cook and keep warm without stoves. So what should we pay attention to when using the cooker?

(1) The cooker shall be installed at a certain distance from combustible materials such as beds, paper ceilings and wooden window frames. Brick stoves used in rural areas should be far away from firewood.

(2) Don't put waste paper, shavings and other combustible materials by the furnace.

(3) Baking clothes should be attended by special personnel.

(4) After the slag is completely extinguished, take out the slag and pour it in a safe place. Pay special attention not to pour slag when the fire is full.

(5) When making a fire, don't burn it with gasoline, kerosene or diesel oil to prevent it from burning violently and causing a fire.

Slide 8: What should I do in case of fire?

In case of fire, you must keep calm and do your best. At the beginning of a fire, it is usually a small fire point, with a small burning area and less heat generated. At this time, just cover it with sand, dry soil, soaked towels, quilts, sacks, etc. , can put out the initial fire. If it is hot, burning or likely to spread, don't try to put out the fire. You should escape from the fire immediately and call 1 19 to inform the fire brigade to put out the fire.

▲ How to report a fire alarm?

1, remember the fire number 1 19. In rural areas, remote areas and other places where there is no telephone or fire brigade, gong, bell, whistle and shouting can be used to call the surrounding police and mobilize the neighbors to put out the fire together.

2. Make clear the fire unit, district (county), street, alley, house number or rural area when giving an alarm.

3. Explain what caught fire and how it was burned.

4. State the name, telephone number and address of the alarm person.

5, after the alarm, arrange people to wait for the fire truck at the intersection and guide the fire truck to the fire road.

6. In case of fire, don't watch it. Some students like to watch fire engines out of curiosity, which is not only harmful to the work of firefighters, but also harmful to the safety of students.

7, can't call the fire alarm. Misreporting a fire alarm is an illegal act that disturbs public order and hinders public safety. Someone is found lying about the fire alarm, so stop it.

▲ How to escape in case of fire?

The fire is ruthless. In case of fire, students should keep a clear head, race against time and leave quickly. If you are trapped in a fire, you should improvise and try to escape.

(1) How to escape from a fire in a bungalow

1, when you are awakened by smoke, get out of bed quickly and rush out of the room. Don't wait to get dressed before you go out. Time is life at this moment.

If the whole house is on fire, you'd better climb to the door and find a wet towel to cover your nose and mouth. Don't go out when the fireworks are closed! You should change other exits and close the doors and windows you pass through to delay the fire from spreading to other rooms.

3. If you are trapped in the house by fireworks, cover your body with blankets or bedding soaked with water, especially wrap your head, cover your nose with a wet towel, and take protective measures before rushing out, the possibility of injury is much less.

Never lie under the bed, under the table or hide in the closet. Don't risk going back to the burning room to save valuables at home.

(2) How to escape from a fire in a teaching building

The floors of modern teaching buildings are getting higher and higher, the structure is complex, the density of students is high, and there are many combustibles such as tables and chairs, so it is difficult to escape in case of fire. Once the building is on fire, you should use the following methods to escape:

1. Don't panic or run around when there is a fire in the building. Quietly explore the direction of the fire, determine the wind direction, and leave the fire quickly against the wind before the fire spreads.

2. In case of fire, if the corridor is blocked by fireworks, the door and indoor ventilation holes should be closed immediately to prevent smoke from entering. Then block your nose and mouth with a wet towel to prevent the inhalation of hot smoke and toxic gases, and wet the upward clothes to avoid fire. If there is only smoke and no fire in the corridor, you can put a large transparent plastic bag on your head to prevent smoke from irritating your eyes and inhaling the respiratory tract, and take a low posture to escape from the fireworks area.

Never jump from the window. If the floor is not high, you can use a rope to descend from the window to a safe area under the protection and organization of the teacher.

4. When there is a fire, you can't take the elevator, because the elevator may break down or be burned out at any time; You should run to the ground floor along the fire safety evacuation stairs; If the fire stairs are blocked, you should immediately return to the roof platform and call for help. You can also break the window glass of the stairwell and shout for help, so that rescuers can know your exact location for rescue.

(3) What should I do after the stairs are blocked by fire?

Once the stairs are burned out, it seems that there is no way out, but it is not.

1, you can climb down from the downspout installed next to the window, but pay attention to check whether the pipeline is firm to prevent the human body from breaking and falling off after climbing up, causing casualties.

2. Tear off the sheets, connect them into a rope, tie one end firmly to the window frame, and then slide down the rope.

The flat roof of the building is a relatively safe place, and you can also take refuge there.

Slide 9: Random talk on common sense of emergency rescue

(1) After rescuing the injured from the fire, three things should be done first.

The injuries that people trapped in the fire may suffer include: poisoning caused by inhaling smoke, burning of respiratory tract and lungs by hot smoke, and some trapped people may be directly burned by fire. If the injured person who has been carried out of the fire has entered a coma or semi-coma, we should do three things morally:

1, unbutton the coat of the injured person, expose the chest, and loosen the belt to dissipate heat;

2. The rescuer puts his hand into the injured person's neck and lifts it, and holds the injured person's forehead with one hand, so that his head leans back to make the injured person's respiratory tract unobstructed as much as possible (when doing artificial respiration, the respiratory tract must be kept unobstructed);

3. Put your ear close to the injured person's nose and mouth to listen to the breathing, observe whether the chest is undulating, whether the pupils are dilated, check whether there is heartbeat and pulse, and confirm whether there is heartbeat and respiratory arrest.

(2) When the heartbeat and breathing stop, give artificial respiration immediately, and don't wait for a second.

At room temperature, the patient felt dizzy after the heartbeat stopped for 3 seconds; 10-20 seconds, the patient had a seizure and fainted; Pupil dilation for 30-40 seconds; Seizures occur in about 40 seconds; Breathing stopped after 60 seconds. Brain tissue is very sensitive to blood hypoxia, and irreversible damage can occur to brain tissue after 4 -6 minutes of respiratory and circulatory arrest.
