The National Climate Center announced on Oct. 22 that this winter in La Niña is a foregone conclusion and that this year's winter could be colder. Recently, with the continuous attack of cold air, all places have begun to cool down, after November 4, the cold current in the west will gradually expand to the east, gradually spread to the whole country, even Fujian guangdong is also under its shroud, this should be the strongest cold wave since the second half of the year! Temperatures in eastern Altay, central Inner Mongolia, southeastern Jilin, southern Gansu and western Henan can even drop by 16°C, while the minimum temperature in the Beijing Plain can drop to about -4°C.
This time the cooling range is large, the amplitude is high, and it is also accompanied by rain and snow, and there will be sleet or rain-to-snow in the eastern part of the northwest region, Inner Mongolia, the western and northern parts of north China, and the northeast region, and there will be heavy to heavy snow in parts of eastern Inner Mongolia, northeast China and northeast China. This time the cold air attack, will lead to a strong cooling in most parts of the country, and even the lowest temperature in China's Jiangnan, southwest and other places is only single digits, so everyone should be prepared for cold heating, this wave of cold is not a joke, but the real climate change!
The weather has become cold, how to heat has become a lot of people need to face the matter, the previous few waves of cold air has made some areas become very cold, some people have also begun to heat work, but sometimes irregular heating methods often endanger our life safety.
On October 27, when the weather in Pingyao County, Shanxi Province, had begun to cool, a family began to burn coal for heating, but it caused a family of four to suffocate and die, the parents and the ten-year-old child died, leaving the 8-year-old son orphaned, the cause of death was that the smoke was too long in the house to cause suffocation.
As soon as this matter came out, many netizens on social media appealed to help a group of children. Many well-wishers generously donated money to their children, not only the local villagers in Cao Village, but also the representatives of enterprises who drove to donate from dozens of kilometers away, and there were many unknown netizens. There are many donations, some donating 10 yuan, 20 yuan, and hundreds of donations, and there are still well-wishers donating. Although everyone's donations make people feel warm, the best way is to popularize common sense with the people around them and try to avoid such tragedies.
Every year when the weather is cold, there are always cases of death due to coal poisoning. On October 13, due to the sudden drop in temperature, the couple surnamed Liu and his wife in Wuqu Village, Changxin Township, Helan County, Ningxia, were still suffering from chronic diseases and were afraid of cold because of their high age. So the two old men lit a fire after dinner to keep warm. The ondol used by local villagers not only burns straw, but is also connected to a coal stove that can burn coal blocks.
After the old man lit the torch that day, he added coal blocks to the coal stove, then covered the coal stove and closed the door to rest. The next day, the old man's son called many times without answering, and rushed home from Helan County in the afternoon, only to find that the second old man had carbon monoxide poisoning, so he rushed to Ningxia People's Hospital for treatment. Unfortunately, the mother died in the hospital on the 16th, and the father also died at noon on the 18th.
In fact, heating poisoning due to coal burning is more common in rural areas in winter. Household coal contains elements of organic matter such as carbon, hydrogen, oxygen, nitrogen and sulfur, as well as very small amounts of phosphorus, fluorine, chlorine and arsenic. When coal is burned, it releases a lot of heat and carbon dioxide in the air, which raises the temperature of the surrounding area. But coal burning brings not only carbon dioxide, but also carbon monoxide that can be deadly.
In general, when oxygen supply is insufficient, alkane compounds produce carbon monoxide. In winter, in order to make the heating effect better, people always like to close the doors and windows, which will cause the air in the room to not circulate, and finally lead to insufficient oxygen in the house, resulting in a large amount of carbon monoxide.
Carbon monoxide is a colorless and odorless toxic gas, after entering the human body, it will bind to the hemoglobin in the blood, which in turn makes hemoglobin unable to combine with oxygen, thus causing hypoxia in the body tissue, resulting in suffocation and death. It should be known that the affinity of carbon monoxide and hemoglobin is 200 to 300 times higher than that of oxygen and hemoglobin, so it is very easy to combine with hemoglobin to form carboxyhemoglobin, and oxygen cannot grab it at all.
Carbon monoxide poisoning is mainly manifested as headache, weakness, dizziness, difficulty breathing during labor, severe flushing, cherry red lips, may be nausea, vomiting, confusion, collapse or coma, and even suffocate death. Even if you are not poisoned to death, if you are in an environment with a low concentration of carbon monoxide for a long time, you will feel headaches, dizziness, memory loss, difficulty concentrating, and palpitations.
Because it is a colorless and odorless gas, it is difficult for people to detect it, and they will only realize that they are poisoned when they feel unwell. Carbon monoxide poisoning can only be detected and treated early to reduce its harm and damage to the brain. Because in the early process of carbon monoxide poisoning, patients usually have no obvious symptoms, only appear as dizziness, dizziness and other discomfort, and accompanied by symptoms such as increased heart rate, so at this time, it is possible to quickly evacuate the gas concentration area, and then quickly give the patient adequate oxygen therapy, which can help the patient recover the oxygen needed by the body despite the needs of the body.
However, if it is found late and too much carbon monoxide is inhaled, it is dangerous. It needs to be quickly sent to the hospital for rescue, including treatment such as hemodialysis, which has a relatively small chance of survival and usually has significant failure in the late stages.
For the occurrence of carbon monoxide poisoning events, the key is effective prevention, we usually use coal, charcoal, gas in the process, we must pay attention to the surrounding ventilation to ensure adequate oxygen supply, to ensure that alkanes can have sufficient oxygen to react with it, reduce the production of carbon monoxide.
In addition, do not use a charcoal fire for warmth when sleeping, when sleeping, people's ability to react to the external environment is almost zero. At this time, if the stove soot is discharged, it is likely to lead to poisoning. Moreover, when burning coal, good quality coal is used for heating, and some low-quality coals not only have a large taste, but also burn insufficiently and are accompanied by a large smell of coal smoke.
Once you feel dizzy, you must ventilate in time, carry the charcoal fire out of the house, and everything is safe. Of course, combustible toxic gas alarms can also be installed at home, so that combustible gases such as carbon monoxide can be warned and the risk can be reduced.
After the emergence of the La Niña phenomenon, it may lead to frequent cold air in our country, and the intensity is strong, this winter may be colder, we must pay attention to maintaining ventilation and smoke exhaust in time when using charcoal fire for heating, do not hold a fluke mentality, once the accident is tragic.
