4 deaths due to biogas poisoning in rural Leshan, how does biogas poison people?

Biogas is a gas mixtureIt contains methane, carbon dioxide, carbon monoxide and other gases, which can cause poisoning if a person breathes this gas for a long time, mild causes dizziness, headache, fatigue, coma, and in severe cases, it directly leads to death.

1. 4 Deaths of 4 Deaths in Rural Biogas Poisoning in Leshan Village, Mata Town, Jingyan County, Leshan, Sichuan, resulting in death. According to the investigation, it was found that the deceased Zhou was poisoned by methane gas when he was pickling pigweed in his cellar, and the other three were relatives of ZhouThese relatives found that Zhou was poisoned, went to the cellar to rescue, and finally all of them were poisoned and died, ** He has been ruled out.

Zhou had no sense of safety precautions, and the other three relatives had no sense of safety rescue, thinking that they could save Zhou, but they didn't expect to take their lives in the end.

I suddenly remembered a drowning person, a relative went into the water to rescue him continuously, resulting in the drowning of 7 members of the family. Blindly saving others not only can't save people, but also leads to putting oneself in danger, and the gains outweigh the losses.

2. How to prevent biogas poisoning? Biogas was originally installed to treat farming manure to obtain energy and improve the environment, but many people suffer from biogas due to improper use and operation. We should always pay attention to the biogas digester in our daily life, if we clean the biogas digester, we should open the various outlets of the biogas digester two days in advance, so that the biogas in the biogas digester can run away through air circulation to prevent human respiratory poisoning.

Also, when working next to the digester, you should leave the digester immediately if you feel uncomfortable, and the working time should not be too long. It is necessary to learn about biogas frequently, such as how to deal with poisoning and management.

When an accident occurs, don't rush to save people by yourself, you should call the police immediately, wait for professionals to rescue scientifically, and don't blindly rescue. If it is urgent, please wear the necessary first aid tools and equipment as well.

Finally: Biogas can not only poison people, if the concentration is high enoughIt can also cause **。If not properly treated, biogas can be a very dangerous gas.

The main component of biogas is methane, methane itself is not toxic, they are poisoned because the biogas in the digester is sufficient and thus lacks oxygen, they are killed because of the lack of oxygen caused by coma, we must pay more attention, similar to the sweet potato cellar, can not blindly enter.

When a person inhales too much biogas, the toxic gas enters the human blood through the alveoli, and quickly combines with the red blood cells in the body to form carboxyhemoglobin, which makes the hemoglobin lose the ability to transport oxygen, causing hypoxemia, and at the same time can also inhibit breathing, resulting in a series of central nervous system symptoms.

The crops and manure in the biogas digester are constantly fermented, and the biogas produces a toxic gas, hydrogen sulfide, a colorless gas with the temperature of rotten eggs, once the concentration of hydrogen sulfide in the air exceeds, it will poison people to death.

Because there is a lot of poisonous gas in the fermentation process, these poisonous gases are not well maintained, so they will be poisoned.

Biogas poisoning refers to the acute systemic poisoning caused by inhaling the mixed gas remaining in the biogas digester during the process of cleaning the digester. If you have a swamp gas poisoning, you should go to a well-ventilated place to rest, unbutton your clothes and pants to promote breathing, and you need to keep warm, because if you get cold, you may have a secondary infection.

The symptoms of biogas poisoning are mainly inhalation, which can lead to typical poisoning symptoms such as dizziness, nausea and vomiting, the most important thing is to accelerate the metabolism and absorption of toxins.

How biogas poisons people:

Biogas is a gas mixture consisting mainly of methane, carbon dioxide, nitrogen, hydrogen, carbon monoxide and hydrogen sulfide. Methane (CH4), also known as "biogas", is a colorless and odorless gas, is the main component of natural gas and coal gas, and is widely present in natural gas, coal gas, biogas, silt ponds and closed cellars, ponds, coal mines (wells) and coal depots.

If the concentration of methane in the ambient air is high, the oxygen content will drop, and people will suffocate, and in severe cases, death. If the methane content in the air reaches 25-30%, it will cause headache, dizziness, nausea, lack of concentration, uncoordinated movements, fatigue, weakness and other symptoms.

There are two main causes of biogas poisoning:

One is that biogas contains a toxic gas - hydrogen sulfide. Hydrogen sulfide is a colorless, rotten egg-smelling gas, soluble in water, and its concentration in biogas exceeds that of headache, fatigue, blindness and other symptoms; When the concentration is exceeded, it can quickly cause death.

Second, when the carbon dioxide content in the air increases to 30%, people's breathing will be inhibited and paralyzed to death. If a person suddenly enters an environment with less than 4% oxygen from fresh air, they will lose consciousness for 40 seconds, and then they will have a spasm and stop breathing. With almost no oxygen in the digester and a carbon dioxide content of more than 25%, a person can immediately suffocate to death if they enter such an environment.

Therefore, safety precautions must be taken when entering the digester.

Distressed! Although the occurrence of such a ** in Leshan is caused by biogas poisoning caused by the fermentation of pigweed, in my opinion, these incidents are ultimately due to carelessness and lack of safety awareness in people's lives. In fact, biogas poisoning is very well understood, the composition of biogas is methane, and the principle of biogas poisoning and gas poisoning is the same.

In my opinion, the incident in Leshan is completely avoidable, but the gourd babies caused in the later stage should not be given away by grandpa one by one. It was already known that the people in the cellar had been poisoned, which showed that the poisonous gas still existed in the air. <>

However, without doing any anti-virus measures, they recklessly went in to save people, and I can only understand that they are eager to save people. But there are a lot of negative teaching materials for such things in society, and I often hear some cases of seeing people drowning, and bravely jumping into the sea to save people but forgetting that they can't swim, resulting in the death of two people, but what I admire the most is that this kind of thing happens around us, and people still don't learn from it at all. <>

It's not that biogas is so deadly, but that biogas itself is deadly when inhaled by the human body. Every year, I hear countless safety accidents, large and small, but every time I find these safety accidents, I find some small flaws from them, that is, accidents can be prevented and prevented in advance. I am also one of them, and I often have a fluke mentality when it comes to safety, which may be because the dangerous things are not done to themselves, and they don't take safety seriously.

Another point is that I found that all of us ordinary people lack knowledge in terms of safety awareness and safety rescue, and they don't know anything about self-rescue technology. I think that on the one hand, we do not pay attention to this reason, and on the other hand, it may be that the current society is still not enough to publicize and train in this area. I want everyone to put safety first, because we represent not only ourselves in this society, but also family and friends.

4 deaths were caused by biogas poisoning in rural Leshan villages, which was caused by the fermentation of pigweed. We usually pickle hogweed outdoors and pack it in a bag. It's safer. Never ferment hogweed in an airtight environment.

Four people died of biogas poisoning in rural Leshan, which was so deadly because some pigweed was pickled in their cellar, which caused the pigweed to be fermented by some substances and eventually produced toxic substances.

Biogas poisoning is mainly due to carbon monoxide poisoning, which leads to a lack of oxygen. The use of biogas requires ventilation to avoid tragedy.

A biogas poisoning accident occurred in a rural village in Leshan, Sichuan, resulting in four deaths. This is a methane poisoning caused by pickled hogweed in a family's cellar. In this kind of underground cellar, the terrain is low and closed, and it is particularly easy to produce biogas, and when the biogas reaches a high concentration, it will cause poisoning to personnel, and may also cause **.

The villagers must pay more attention.

4 deaths from biogas poisoning in rural Leshan, these biogas are some pig manure and pig grass, these biogas contains toxins, as long as the human body inhales it will be fatal.

4 people died of biogas poisoning in Leshan countryside, which was emitted by pickling pigweed in the cellar pond, and at the same time, it was also very harmful, resulting in 4 people dying of poisoning.

The cause of the accident was a villager who was poisoned by methane gas while pickling pigweed in his cellar. Subsequently, the villager's nephew, son and daughter-in-law, found him lying in the cellar to prepare for the rescue, only to have died of methane poisoning.

On the morning of November 15, 2020, a family biogas poisoning incident occurred in Group 4 of Qipanshan Village, Mata Town, Jingyan County, Leshan City, Sichuan, which was caused by a 66-year-old villager Zhou Mouguang who went to his kiln to pickle pigweed, but because the fermentation of pigweed produced biogas and poor air circulation in the cellar, the space was narrow, resulting in biogas poisoning in Zhou, and Zhou Mouguang fell into a coma in the kiln pond. The other three people in the family, Zhou Mouguang's nephew Zhou Mou'an, his son and Zhou Mouhong's daughter-in-law, found that Zhou Mouguang had not responded for a long time, and realized that something might have happened, so they went down to the cellar to meet the rescue, but due to the high concentration of biogas, they were poisoned and collapsed, and they were all rescued and declared dead. <>

This case is very regrettable, because of the blind rescue, which led to the death of three people on the spot. Due to the presence of microorganisms, the presence of microorganisms, the relatively closed environment and the poor air circulation, it is very easy to produce biogas. When the concentration of biogas is high, it is very easy to cause human poisoning, and it is also very likely to produce**.

In the event of a poisoning incident in these places, in the case of poor air circulation, you should not rush to the rescue yourself, but should immediately call the police and ensure your own safety. When emergency personnel rescue, they should wear gas masks, wear protective clothing, and be fully prepared to go down to save people. Don't do the gourd baby to save grandpa, send them one after another, otherwise it will happen to Zhou Mouguang's family.

Correct practice in places where methane poisoning occurs:

The first is to observe whether there is gas outside, and then look at whether there is a flickering fire inside, observe whether there is a possibility of **, and if there is a possibility of immediately evacuate to a hundred meters away.

Second, in the case of air circulation, evacuate the poisoned person from the scene immediately and call 120 to call the police.

Third, unbutton your clothes and trouser belts while waiting for help to keep your airway open. At the same time, keep warm to prevent cold and secondary infection.

Fourth, patients with mild poisoning generally do not need special treatment, and if there are conditions around, they can take painkiller tablets, Chlordiamine and other drugs according to the patient's situation. Patients with moderate and severe poisoning should be sent to the hospital for emergency treatment in time. <>

We need to prevent mass poisoning, not blindly carry out rescue.

Outburst! In the case of biogas poisoning in the rural area of Leshan, patients with biogas poisoning should not blindly rescue, but should arm themselves, wear gas masks, wear protective clothing, and make adequate preparations to help other people.

In this case, the first thing to do is to quickly transport the patient to an open place with fresh air, and then quickly call the first aid**, and if necessary, take emergency measures to send it to the hospital, and hurry**.

Outburst! In the case of biogas poisoning in rural Leshan, patients with biogas poisoning should be transferred in time to a place with better air circulation, and then help the patient unbutton his clothes and call 120 for help.

Outburst! In the case of biogas poisoning in rural Leshan, patients with biogas poisoning should be dragged to a ventilated place in time, and then unbuttoned their clothes, and at the same time, they should be sent to the hospital for rescue in time.

The poisoned person should be quickly removed from the scene (rescuers must wear aerobic protective masks) and sent to the hospital, and if possible, hyperbaric oxygen chambers. Before paramedics arrive at the scene, artificial respiration is administered to the poisoned person.

Outburst! There is a methane poisoning incident in the rural area of Leshan, and patients who encounter biogas poisoning should leave the place with biogas as soon as possible to breathe fresh air, etc.

Four people have already died. When we learned the news, we were very saddened, and 4 very healthy lives left us forever.

Four people died in the accident. On November 15, Zhou Mouguang in Jingyan County, Leshan suffered from methane poisoning in his own cellar and pickled pigweed, and his relatives Zhou Mou'an, Zhou Mouhong, and Zhang Mouqiao found that Zhou Mouguang was poisoned, and he did not do protection to save people, and unfortunately all of them were poisoned by biogas, and died after rescue.

Biogas is an organic gas that, in a confined space, causes a decrease in oxygen content. If a person is in a biogas area, a place with a relatively high content will lead to a lack of oxygen, resulting in biogas poisoning. The methane poisoning in rural Leshan has killed four people.
