　　Three or five friends sat around the fire to make tea, and the tea was fragrant; Paired with freshly baked sweet potatoes, oranges and chestnuts, the atmosphere is full. However, with the popularity of cooking tea around the stove, many people "try early" at home, causing safety problems such as carbon monoxide poisoning.

　　Fire experts suggest that it is not recommended to use charcoal fire to cook tea indoors. Insufficient combustion of charcoal will generate carbon monoxide, and excessive concentration will cause life-threatening. Even if it is fully burned, the oxygen content is declining, which is also harmful to health. In addition, it is necessary to guard against fire risks caused by open flames and high temperatures.

　　Closed indoor measurement: it only takes 15 seconds for the carbon monoxide detector to give an alarm.

　　A few days ago, a man in Shanghai reported to the police that two of his friends suddenly fell into a coma while eating. After the police arrived at the scene, they found that a charcoal stove for cooking tea was burning in the room, so they immediately took the charcoal stove to the rooftop and opened the window for ventilation. Fortunately, the three people were treated in time and were out of danger.

　　Recently, cooking tea around the stove has become a popular item for tea room leisure and family gathering. It is recommended to punch in, share equipment and ingredients, take photos and videos … … There are more than 750,000 notes about cooking tea around the stove in Xiaohongshu, and the popular videos about experiencing cooking tea around the stove in Tik Tok have attracted more than one million praises. According to the data of Tianyancha, nearly 30 enterprises in the name of cooking tea around the stove have been established in China recently, and related trademarks have been registered by many parties.

　　Cooking tea around the stove is a beautiful thing, but if it is done in a closed room, it will easily cause carbon monoxide poisoning. "Carbon monoxide is colorless and tasteless, and it is not easy to be detected. If the concentration exceeds 0.05%, it will cause harm to the human body." Chen Yuan, an engineer at the Fire Control Technology Division of the Fire Rescue Detachment in Huangpu District, said, "Mild carbon monoxide poisoning is characterized by severe headache, dizziness, weakness of limbs, nausea, vomiting, mild disturbance of consciousness and lethargy, and patients with coronary heart disease may have angina pectoris. If it is not treated in time, it will be life-threatening. "

　　The experiment of cooking tea around the fire in Huangpu District, Shanghai shows that in a closed room of about 60 square meters, only 15 seconds after the firemen lit the charcoal fire, the carbon monoxide detector gave an alarm. At 1 minute and 50 seconds, the concentration of carbon monoxide has exceeded 0.01%.

　　Improper operation of cooking tea around the stove has caused many accidents and casualties. During the Spring Festival this year, a mother and son in Yangzhong, Jiangsu Province, used a cast iron charcoal stove to cook tea at home. Because of the cold weather, they closed the doors and windows and died of poisoning. In January this year, a woman in Weifang, Shandong Province was cooking tea around the stove at home. After 3 hours, she felt a little unconscious and accompanied by vomiting. She went to the hospital for examination and found that it was moderate carbon monoxide poisoning.

　　Chen Yuan analyzed that compared with oxygen, carbon monoxide binds to hemoglobin in blood faster and dissociates more slowly. Carbon monoxide takes up a lot of hemoglobin, which will make the human body lose the ability to carry and transport oxygen, thus leading to poisoning. In addition, carbon combustion will consume oxygen and accumulate carbon dioxide; When the indoor oxygen content is as low as 10%, it may be life-threatening.

　　Fire risk should not be underestimated.

　　Due to the problems of open fire, continuous high temperature, uneven quality of ovens and unskilled operation, fire experts also highlighted the fire risk behind cooking tea around the stove.

　　— — Produce open flames and high temperatures. "When it is lit, Mars splashes out, especially if you can’t fan the wind. The more fans there are, the more Mars there are. Fortunately, there is nothing easy to burn on the table, otherwise I am really worried about the fire. " Ms. Zhang, a citizen of Beijing, said.

　　Gao Yan, supervisor of the comprehensive guidance section of the fire rescue detachment in Putuo District, Shanghai, explained: "On the one hand, the charcoal burning time is too long and the temperature is too high. If you accidentally knock over the stove, it may cause combustible materials to burn. On the other hand, it takes a long time for the charcoal fire to burn out. If you forget to put it out after cooking tea around the stove, it may also cause a fire. "

　　— — The quality of the oven is uneven and the operation is unskilled. The reporter noticed that the tools for cooking tea around the stove are very simple: a charcoal fire oven made of cast iron or pottery, a mesh baking tray, a teapot and some charcoal. E-commerce, group buying and other platforms are sold, and the package price ranges from tens of yuan to one or two hundred yuan.

　　"It only burned twice, and the chassis burned a hole." In a photo taken by a buyer, the hole in the bottom of the cast iron charcoal oven is clearly visible. A number of interviewees said that the oven they bought was not insulated: "The temperature on the outer surface of the oven was very high, and the first operation was unskilled, which burned the table."

　　— — There is an overload of electricity. Some businesses began to use electricity instead of charcoal fire. In the Yijing Xiaoshe Tea Room in Putuo District, Shanghai, the electric oven used by merchants is similar in shape to a pottery oven. After being electrified, the resistance wire is red and hot, and the high temperature on the surface of the oven can be felt by touching it with your hands. "At first, we used charcoal to cook tea around the stove. Later, for safety reasons, we changed to electricity, and the customer’s acceptance was not bad." The person in charge of the store said.

　　Gao Yan suggested that changing carbon to electricity can really avoid carbon monoxide poisoning and other problems, but the fire risk of using this electric furnace still exists. Most of these electric furnaces are high-power electric equipment, which is easy to cause pressure on the circuit. Especially, it is possible for multiple boxes in the teahouse to use multiple electric furnaces at the same time, so it is necessary to prevent fires caused by overload electricity.

　　Tea should be cooked well and safely.

　　In order to cook tea around the stove safely and comfortably, Chen Yuan suggested that we should start from all aspects and standardize the safe operation at every step.

　　First of all, before cooking tea around the stove, you should buy utensils in regular shops and platforms, and you can’t find charcoal burning tools at will.

　　Second, try to choose outdoor places with open ventilation such as terraces and rooftops. If it must be carried out indoors, it is necessary to keep the windows open and ventilated, and it is best to use smoke extraction facilities.

　　Third, during the cooking process, reasonably adjust the spacing of items, stay away from combustible materials, and put heat insulation pads under the stove. At the same time, prevent children from approaching or touching charcoal burning equipment to prevent accidents such as burns. "Try to avoid baking things with high oil content, otherwise a large number of oil droplets will fall into the charcoal and the flame will soar." Chen Yuan added.

　　Finally, the charcoal fire must be extinguished after the tea is cooked around the stove. It is best to take the stove outdoors and add water to cool it, or wait until the charcoal burns out and completely ashes.

　　Ms. Ma, a citizen of Shanghai, suggested that the merchants who cook tea around the stove explain the precautions to customers in detail in advance. "Some merchants default that customers understand the procedures for cooking tea around the stove, and do not give necessary safety reminders. Customers can operate whatever they want, which has certain security risks."

　　Gao Yan suggested that customers should first understand the safety exits and evacuation passages when entering the tea room, and check the location of fire extinguishers such as fire hydrants. It is suggested that businesses should add fire extinguishing appliances. If electric furnaces are used, businesses should regularly check whether the circuits are aging and whether the electric furnaces are normal, and avoid connecting multiple high-power electrical equipment to the same socket at the same time.
