How did people die in the fire?

In the fire, of course, people will have a variety of death methods.

For example, burned to death, roasted to death, drowned, jumped to death, suffocated ... ... but 89% are smoke dead. Well, you must make sure that the smoke is dead.

What's the reason that smoke is dead? This truth is actually quite simple. No one is stupid enough to run into the fire. He always thinks of ways to avoid the bright and hot fire.

However, the smoke is different. Smoke is relatively unpleasant. Most people, who may be about 90% of the population, do not take tobacco as a matter, or even do not know that there is smoke, and the result will be glorious and even heroic.

Like Cheng Jinjin, smoke has three axes and is simple, but it kills countless people.

1 axe: dangmen, high temperature kill you

Flue gas, a few hundred Baidu that is often something, is not rare as high as thousands of degrees. These figures, many people have no concept, what meaning, three Baidu? Five Baidu and I have a few cents relationship?

Of course, there is a big relationship. Let's use an analogy. When water burns, it will boil and it will open. If there is a huge pot of boiling water here, slamming the ground and braving children, the village chief comes and says: Zhang San, the blisters are lovely. You put your head in and you don't, okay? Of course you will not do it, and you will boil 10,000 grass horses in your heart. Head in, don't say for three minutes, insist on three seconds, and all come out with a full bag.

However, some Baidu smoke, someone dared to rush into it. What are the consequences? When you go to the hospital to see it, you know: Those who are really brave, full of blisters, big or small; breathless, and there is a knife in the throat and a pipe. Of course, more often than not, you don't have to go to the hospital at all, because the warriors died in the tens of seconds that they had rushed into the smoke, and they had no chance to go to the hospital. High temperatures will not only burn the skin, but more troublesome, it will make the respiratory edema. If you inadvertently swiftly sift through eight Baidu flue gas, then you'll be sour. You can't breathe in the second breath again. Because it's swollen, it's blocked, and you can only hang it.

Chin: At 2 o'clock on the morning of June 25th , 2015 , the meter box on the bottom floor of a unit building in Xiguan Hutun Community, Zhengzhou City, Henan Province caught fire. Fifteen people living on the seventh floor ran into a smoke-filled staircase and tried to escape to the building. The result was all. death.

2 Cleaver: licking your ears, poisoning you

Smoke is of course toxic. What is poisonous? It depends on what is burned. Burning sweet potatoes and burning sofas are certainly not the same. The average guy even burns carbon monoxide and carbon dioxide, but plastics, sponges, etc., these may burn advanced babe such as hydrogen cyanide and sulfur dioxide. Of course, no matter how senior and low-level, they must not despise these poisonous gases.

For example, carbon monoxide. It is colorless, odorless and fluttering. You don't know it in your nose. It can bind intimately with hemoglobin, the binding force is about 250 times that of oxygen , and dissociation is 3600 times slower than oxygen .

These words really TNND difficult to understand. Let's talk informally: every cell in our body is going to eat oxygen, and we die when we don't eat it. People suck oxygen into the lungs through the nose and the respiratory tract, where they then enter the bloodstream. Hemoglobin in the blood is like a big truck that specializes in oxygen. Oxygen collapsed and jumped into the car. Then he went to a certain cell, such as the foot. He jumped off and got out of the car. He had oxygen on his feet. At this time, carbon monoxide came, I'm sorry, it collapsed, jumped into the car, and it jumped nicely. It jumped to 250 , and oxygen was still on the ground. At the same time, the carbon monoxide that jumps into the car is not willing to get off the train. 3,600 oxygen jumps . The old man is still sitting in the car. In this proportion, it takes less than tens of seconds to fully sit on a truck full of carbon monoxide, and your feet wait. Oxygen does not come and the cells are hungry. Of course, the feet are not tight, the cells in the head are hungry and cry even worse. You also have hearts, livers, legs and hands. The consequence of carbon monoxide on the car is that you know it is bad. TMD has a bad dish. Your eyeballs are moving, but others can't move. You can only blink at this time, and of course it will not take long. Isn’t it all starved to death, or is it a fire that has been burned...

Most of the poisonous gases are those that engage in your breathing, or that are involving your nerves. When you are in large quantities, you will see Marx when you take a sip. There is a lot to say here: Do not put on a towel to prevent poisoning? Because these poisonous gases are all molecular size, they are so small that they can completely penetrate the towel and penetrate into your throat. To say that the eight layers of towels can be poisonous, all of them are gods and geese. These fairy sayings are not used by birds.

Chestnut: 2007 May 20 evening, Zaozhuang City, Shandong Province called Tumen barbecue restaurant, the second floor has nine guest table, because Mao Haizi playing with fire. Nine people were completely unaware of the sealed room and eventually died of carbon monoxide poisoning.

3 Cleaver: Digging your eyes, killing you in dark

In some cases, the temperature of the smoke may not be too high and the poison gas is not much. But it was too dark. He couldn't see it. He couldn't reach out.

Of course, when a large amount of smoke is full of space, oxygen is also squeezed out. When the oxygen content in the air is reduced to 15% , people's muscle activity is decreased; when it is reduced to 10-14% , people are weak in limbs, mental confusion, and unclear direction; when it drops to 6-10% , people will Will faint. The short-time lethal concentration of oxygen is 6% , while the actual oxygen concentration in the room can sometimes reach about 3% .

Soaked in such smoke, your eyes are sour and hot. You don't know where the road is. Well, you can only fumble forward. This kind of progress is very slow, and there will be many accidents, such as which pit fell into the pit, or a few turns back to the original place. At this moment, your mood is collapsing and breathless. If you do not jump downstairs, you will feel sorry for yourself.

Need to say one more thing is that our firefighters often encounter such a situation. Although they have an air respirator to protect their own breathing, it is difficult to overcome the darkness and it is still very difficult to find individuals. Therefore, fire extinguishing is not simple, saving people is even more troublesome.

Outside the three axes, we know that smoke is not just gas, and there is a lot of slag. These slags, with particle diameters ranging from a few microns to several tens of microns, can enter the human lungs to adhere to and accumulate on the alveolar walls due to diffusion, causing respiratory diseases and increased heart disease mortality, causing indirect harm to humans. .

If you're lucky enough to escape the three tricks, that's fine, you're really big.

We all know that living is the absolute truth. When they are alive, they will plant sweet potatoes, drink sweet potatoes, make a tiger, make a complaint, and write several books.
