In the event of a fire, do not close the doors and windows

It depends. 1. In the event of an outdoor fire, close the doors and windows to prevent it from burning in.

2. If there is toxic smoke, you can open the window appropriately and ventilate it.

Look at whether your window is a fireproof window, it is best to close it for fireproof, and it is best to close it when it is not a fireproof self-rescue (high-rise), and open the window at the lower floor to jump.

A: You can't open doors and windows casually.

Opening doors and windows will replenish the oxygen in the house, which will contribute to the fire, and doors and windows should not be opened casually. If there is a fire in the corridor outside the house, opening the door will cause smoke to enter the house and endanger life. But if you want to escape, of course, you should open the doors and windows to escape under the premise of safety, or open the window to call for help, so b, c, d are not right.

In the event of a fire, be sure to stay calm and do what you can. In the initial stage of fire, it is generally a small fire point, the burning area is not large, and the heat generated is not much.

How to deal with a fire.

When a fire breaks out, if it is found that the fire is not large and has not yet caused a great threat to people, when there are enough fire-fighting equipment around, such as fire extinguishers, fire hydrants, etc., the small fire should be controlled and extinguished; Don't panic and scream and scurry, ignoring small fires and causing a catastrophe.

In the face of smoke and flames, you should first force yourself to stay calm, quickly judge the dangerous location and safe place, decide how to escape, and evacuate the dangerous place as soon as possible. Don't blindly follow ** and crowd each other and rush around.

Anyone who discovers a fire should call "119"** for help as soon as possible and report the fire to the fire brigade in time. Children and the elderly, the weak, the sick and the disabled in the fire scene do not have the ability to save themselves or have lost the ability to save themselves, and other people present at the scene should actively help them escape from danger as soon as possible in addition to saving themselves.

A should be chosen. Whether the doors and windows are opened should depend on the specific situation, if the smoke in the closed room is very large, and there is no fire, in order to reduce the smoke concentration, so that the internal personnel will not have accidents due to suffocation, and at the same time facilitate the escape for help, the correct way is to block the gap in the room with a wet cloth, and at the same time open the doors and windows leading to the outside for smoke exhaust and seek help. If there is already a flame in the room, opening the doors and windows rashly at this time will promote the spread of the fire and increase the fire danger

Do not open doors and windows casually, as opening doors and windows will replenish the oxygen in the house and contribute to the fire.

The source of fire is the source of fire, and it is also the direct cause of burning and **. Dry firewood, wood, wood near the stove or flue, combustible dust and fibers that accumulate on the high-temperature steam pipes; Paper, clothing, etc., next to high-power light bulbs, will cause burning if they are baked for too long.

Everyone must pay attention to the fact that in the event of a fire, you must call 119 fire alarm in time, do not watch, the fire is extremely dangerous, it may be at any time, do not watch!

The right thing to do in the event of a fire in a relatively closed room:

First of all, you should touch the door with the back of your hand, try to see if the door has become hot, if it is hot, the door should not be opened, otherwise smoke and fire will rush into the bedroom; If the door is not hot, the fire may not be large and it is possible to escape the room by normal means. After leaving the room, be sure to close the door behind you to prevent the spread of fire.

If you feel hot when you touch the door with your hand, once you open the door; Flames and smoke are bound to rush in. First of all, you should close the doors and windows facing the fire, open the doors and windows of the back fire, plug the door cracks with a wet towel or soak the quilt with water to cover the doors and windows, and then keep drenching the room with water to prevent the smoke and fire from penetrating in, and stay in the room until the rescuers arrive.

The heat flows upward, so you can't open the doors and windows above, so you won't have the same effect as a smoke window, and when someone is in the fire, you have to go down, you can't go to a high place, and the result of going to a high place is almost the same, if you don't get burned to death, you will be smoked to death, and then you can successfully jump off a building and fall to your death, and the smoke is also upward, so you have to lower your center of gravity, and if you can climb out, you can climb out, so that if you open the low door, you will give oxygen to the fire, but it won't be burned to the point that the probability of people running out is much greater, and it is relatively better to open the window. Opening the window is good for the firefighters to extinguish the fire, and the worry that the fire will burn more when you open the window is unnecessary is unnecessary. Even if the window is closed, the rear window will be broken.

When the firefighters came, they instinctively damaged the pie in front of the window to help extinguish the fire. In order to extinguish the fire quickly, open the window in the event of a fire and determine the situation (wind direction, firefighter rescue progress, fire size, direction, degree of burning and smoke, etc.)!! If you can't delay the time by cleaning your luggage and valuables because of the escape, **, if you find that the passage is blocked, you should close the door and open the window to escape safely.

If you can get out of the house smoothly, open and close the doors and windows according to the situation if possible!! If a household liquefied gas tank catches fire, in addition to covering it with soaked bedding and clothing, you can also sprinkle dry powder or baking soda on the flame root Huihebu vigorously, and close the valve while the fire is extinguished. But the train must not open the window!

The windows should be closed immediately to slow down the burning of the fire and allow more valuable time for the escape. More than 95% of the deaths of blind people trapped in fires are caused by smoke, so the upper buildings must ensure the smooth operation of the smoke prevention and exhaust system. In addition, high-rise buildings of more than 100 meters are required to set up a refuge floor on the middle floor, and in the event of a fire, the building personnel can evacuate along the safe evacuation channel or save themselves through the sliding rope.

In the event of a fire, you can't open the doors and windows casually, because once the doors and windows are opened, a large amount of fresh air will pour in, and the fire will develop rapidly, and at the same time, a large amount of smoke will pour in, which is easy to poison and suffocate people to death. At the same time, due to the convection of the air, the flame will rush outward, so in the event of a fire, the doors and windows cannot be opened casually.

In the event of a fire, do not panic, stay calm, and quickly dial 119 for help, and quickly choose the correct escape route. In the event of a fire, do not walk upright when the smoke is thick, move forward with a low posture, wrap the whole body with wet sheets, wet blankets, etc., and cover your mouth and nose with a wet towel to avoid choking and poisoning. When evacuating, you should choose stairs or exits with safety exit signs, and remember not to take the elevator.

If you find a closed room**, do not open the doors and windows casually to prevent fresh air from entering and expanding the combustion. Check the fire from the outside first. If the fire is small, or if there is no smoke but no fire, you can prepare water for extinguishing the fire with a bucket or basin, and quickly enter the room to extinguish the fire.

It depends. When the room caught fire, the fire in the room was small, but when the doors and windows were suddenly opened, the fire suddenly became larger and difficult to extinguish. This is mainly due to the lack of air circulation in the originally burning room, the lack of oxygen in the room, once the doors and windows are opened, a large amount of fresh air flows in, and the fire spreads rapidly.

If you don't know what stage of the fire is in the room where the fire is on, try not to open the doors and windows. If there is only smoke in the fire room and there is no flame, it is generally just starting to catch fire, so you can go in to check and extinguish the fire source as soon as possible. If there is an open flame, it means that the fire is already in the development stage, and you can't open the door casually at this time, and then open the door to extinguish the fire after preparing sufficient fire extinguishing agent.

After a fire occurs, the doors and windows of the room close to the burning room should also be closed in time to reduce air convection and prevent toxic smoke from entering the room and causing trapped people**.

MUST ... The person in charge will not circulate and suffocate.

Personally, what I think is correct should be A

The reason is: "only" is too absolute, sometimes open the door and open the window are another way to escape, for the ground floor or the floor is not high, open the window to escape the fastest, then for the high-rise if the window is opened, first of all, you can not jump down, jump will die, and after opening the window to cause ventilation, the fire will be more vigorous. If "the doors and windows are not opened", then they can only be suffocated or choked to death.

So, be improvised!

A should be chosen. Whether the doors and windows are opened should depend on the specific situation, if the smoke in the closed room is very large, and there is no fire, in order to reduce the smoke concentration, so that the internal personnel will not have accidents due to suffocation, and at the same time facilitate the escape for help, the correct way is to block the gap in the room with a wet cloth, and at the same time open the doors and windows leading to the outside for smoke exhaust and seek help. If there is already a flame in the room, opening the doors and windows rashly at this time will promote the spread of the fire and increase the fire danger

Of course I chose A in the event of an indoor fire.

In the event of a fire, do not open doors and windows casually. If the door is opened at will, it is likely that a large amount of oxygen will pour in, causing the fire to become larger.

If the lock temperature is very high, or smoke is drilling through the crack in the door, it means that the fire or smoke has blocked the door exit, so do not open the door rashly. If the temperature of the door lock is normal or there is no smoke coming through the crack of the door, it means that the fire is still some distance away from you, and you can open a crack in the door to observe the situation of the outside passage.

When opening the door, you should use one foot to resist the lower frame of the door to prevent the hot air wave from rushing open the Tonghang door and promoting the spread of the fire.
