In the event of a fire, you can cover your mouth and nose with something or nothing

In the event of a fire, you can cover your mouth and nose with a damp towel. Because fires produce a large amount of carbon dioxide gas, people can suffocate when they breathe in too much carbon dioxide, and the carbon dioxide gas will generally be suspended on the top of the space. People cover their mouth and nose with a wet towel to prevent excessive carbon dioxide inhalation, and bend down to lower the mouth and nose of the body as much as possible, which is conducive to escape.

Carbon dioxide can generally be prepared by calcining limestone at high temperature or by the reaction of limestone and dilute hydrochloric acid, and is mainly used in refrigerating perishable food (solid), as a refrigerant (liquid), in the manufacture of carbonized soft drinks (gaseous) and as a solvent for homogeneous reaction (supercritical state). Regarding toxicity, studies have shown that low concentrations of carbon dioxide are not toxic, while high concentrations of carbon dioxide can poison animals.

In order to prevent choking on smoke from the fire ground, you can use towels and masks to cover your nose and evacuate prostrately. The smoke is lighter than the air and floats on the upper part, and evacuation close to the ground is the best way to avoid smoke inhalation and filter out toxic gases.

If you do not have these protective gear, you can pour cold water on your head or body or wrap your head and body with wet towels, wet quilts, wet blankets, etc., and then rush out. It's better to have multiple protective tools in hand than to use your bare hands.

Stay calm. 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. If the passage has been blocked by fireworks, you should leave with your back to the direction of the fireworks, and escape outdoors through balconies, air windows, rooftops, etc. Only when people are calm and calm can they come up with a good solution.

If you are in danger, you should evacuate as soon as possible, and do not waste your escape time on finding and removing valuables because you are shy or concerned about your valuables. Those who have escaped from danger must not return to danger and throw themselves into the net. Where there is life, there is hope.

Because fires produce a large amount of carbon dioxide gas, people can suffocate when they breathe in too much carbon dioxide. Normally, carbon dioxide gas is suspended at the top of the space.

Therefore, when a fire breaks out, people should cover their mouth and nose with a wet towel to prevent excessive carbon dioxide inhalation, and bend down to lower the mouth and nose of the body as much as possible, which is conducive to escape.

In the event of a fire, cover your mouth and nose with a wet towel to insulate yourself from the toxic gases that burn, and gases such as carbon dioxide float upwards as the temperature rises, so you have to bend over or lie on your stomach.

Make sure to bend over and lower the mouth and nose as much as possible. Because the fire produces a large amount of carbon dioxide gas, people can suffocate when they breathe in too much carbon dioxide. In the face of thick smoke and fire, first of all, you must force yourself to stay calm, quickly judge the dangerous place 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.

Causes of the fire:

There are many reasons for the occurrence of disasters, mainly including human insecurity, material insecurity, and natural disasters.

management deficiencies and so on. According to the analysis of fire data.

The vast majority of fires are caused by human factors such as smoking, careless use of fire and electricity, and operation in violation of safety regulations.

Common causes of fire include: playing with fire, setting off fireworks, spontaneous combustion, lightning strikes, static electricity, residual fire, suspected arson, electrical fires (leakage, short circuit, open circuit, overload, contact resistance.

Excessive voltage, overvoltage or undervoltage, phase loss operation, etc.), production operations (cutting, refining, chemical production, mechanical equipment failure), careless use of fire, etc.

Now, no matter what time it is, we are very stressed about how to save ourselves in a fire, especially in primary and secondary schools. The method of self-rescue for fire is engraved in the emphasis, always add that we should hold a wet towel to cover our mouth and nose in the fire. Then bend over and leave the scene, why is this, let's discuss why this is done in the fireIn my opinion, in the fire, cover our mouth and nose with a wet towel because we want to ensure that we do not inhale harmful gases, and we have to bend down to leave the field may have something to do with the density of the gas, so when the teacher teaches us, we must bend down and leave the scene, now we will go to explore the secret, why do we do this.

In the event of a fire, cover your mouth and nose with a towel and bend over to leave the scene, mainly because covering your mouth and nose with a wet towel allows us to inhale less carbon dioxide. Whether it's the firefighters teaching us how to escape from the fire, or in school, the teacher's education to us is to teach us that when there is a fire, we must cover our mouth and nose with a wet towel, and then bend down to leave the scene, because we cover our mouth and nose with a wet towel, and then we leave the disaster scene, so that we can make sure that we inhale less carbon dioxide, and then the carbon dioxide in or in the towel will merge with the water in the towel. In this way, we will inhale less carbon dioxide, which is conducive to protecting our body, preventing us from being more injured in the fire, and allowing us to leave the scene smoothly without any physical injury.

In the fire, you should cover your mouth and nose with a wet towel, bend over, and leave the scene because there is a large amount of carbon dioxide in the fire, and the density of carbon dioxide is less than the density of air. In the fire scene, when we want to escape, we have to cover our mouth and nose with four towels, bend over because the density of toxic gases burned in the fire is relatively small, and carbon dioxide when burning, their density is relatively small, so it will float above the air, if we don't bend over and walk at the fire scene, we will be unconscious because of lack of oxygen, and then we can't escape from the scene, and the density of oxygen is relatively large, the density of oxygen is greater than the density of air, so oxygen will sink at the bottom of the airTherefore, when a fire breaks out, there will be more oxygen in the place below, so bending down is to give yourself more oxygen and not cause suffocation.

When we want to flee the scene of a fire, we usually cover our mouths and noses, and we also bend over to walk, because we cover our mouths and noses to prevent inhaling toxic gases, and bend down to get more oxygen.

Covering the mouth and nose with a wet towel can effectively block the toxic gases and soot generated by the fire from entering the human body through the mouth and nose, and reduce the suffocation and poisoning caused by the trapped personnel. Bending over and leaving the field can reduce the risk of people falling and falling down from burned buildings, furniture, etc., and increase the escape rate.

Because the most lethal thing about the fire is the smoke and dust, then the wet towel can isolate part of the smoke and dust, and the fire is going up, and the smoke and dust are also rolling upward, so it is natural to bend over and leave the scene in an orderly manner.

Because in this way, the smoke will not choke on the mouth and nose, causing suffocation and bending over to leave the field, because the fire below is the weakest.

Because when you cover your mouth and nose with a wet towel, you can prevent smoke from entering your mouth and nose, and you can ensure that we breathe normally.

Because this can block part of the smoke from inhaling into one's own respiratory tract, avoiding burns, bending down can also reduce the amount of smoke inhaled, after all, the smoke goes high.

If you use a wet towel, you can prevent some smoke from entering your nose or mouth and damaging your throat, and you will not be choked by the smoke, and then suffocated, as for bending over because the smoke is running up after the fire, you can still breathe a certain amount of air below, and if you bend over, you can see more things, which is very helpful for escape.

Because the wet towel has moisture and can't absorb the smell of smoke, bending over can protect your head from being smashed, and if you straighten your waist, what falls will hit your head as soon as possible
