Yangtze River ** Wuhan Client, January 10 (Reporter Xie Binglin, correspondent Han Xiao) The winter weather is cold and gloomy, and the unique ritual and atmosphere of "cooking tea around the hearth" is favored by residents. Make a charcoal fire, boil tea and roast some fruits and dried fruits at the same time, which is very pleasant. While we enjoy this comfort, we don't know that this behavior also has hidden dangers.

Cooking tea around the hearth is inseparable from the "stove", and the charcoal stove is the first choice to create the so-called "fireworks" atmosphere. At present, many of the stoves sold on the online platform are cast iron and ceramic ovens, as well as ovens with integrated table and stove. When the furnace is in a high temperature state for a long time, if flammable and explosive materials are placed around, the charcoal fire is slightly not carefully controlled, and it is very easy to cause a fire.
On February 5, 2022, when an elderly man in Bazhong, Sichuan Province was alone at home with charcoal, the charcoal fire accidentally ignited the tablecloth, and then the old man's clothes were also burned, and the old man was unable to save himself, so he had to go to the street for help. Several enthusiastic neighbors carried water to extinguish the fire on the old man, and the old man was taken to the hospital by his family for treatment.
On January 6, 2024, a suspected poisoning incident caused by the use of a coal stove for heating occurred in Yulin City, Shaanxi Province, resulting in the death of four people.

On January 9, Wuhan Fire Department discovered the risk of "cooking tea around the hearth" through a set of simulation experiments. Firefighters set up a fire in a closed room, and through the thermal imaging camera, it can be seen that as the fire burns, the temperature of the furnace has reached more than 400 degrees, which exceeds the ignition point of many combustibles in our lives. At the same time, firefighters put some oranges, walnuts, and red dates on the stove for baking, simulating the scene of "boiling tea around the stove". After a period of time, the bottom of oranges and walnuts has been charred and blackened, and if the baked items are not removed in time or the personnel are temporarily away from the stove, it is very easy to cause a fire.
In addition, some members of the public use stoves for indoor heating, or use open flames indoors to make smoked bacon, croquettes and other Chinese New Year goods. These behaviors will bring certain potential safety hazards, so we should pay special attention to ensure that there are no flammable and explosive materials around the open flame in the process of using the open flame, so that "the fire does not leave the person, and the fire does not leave the person", and the open flame should be completely extinguished after use, and then leave after confirming that there is no possibility of re-ignition.

In addition to the risk of fire, "cooking tea around the hearth" in a confined space can easily cause carbon monoxide poisoning. Incomplete combustion of charcoal will produce colorless, odorless and toxic carbon monoxide, and when the concentration exceeds the standard value, it will cause discomfort, serious and even life-threatening.
The fire was lit in a closed room, and after 10 minutes, a toxic gas detector could see that the concentration of carbon monoxide (parts per million or more) reached 50 (above) and an alarm sounded. After 30 minutes, the concentration of carbon monoxide (parts per million) has reached 98, and the body has a slight discomfort. After 1 hour, the concentration of carbon monoxide (parts per million) has exceeded 130, and the indoor personnel have symptoms such as dizziness and nausea. Therefore, when we "make tea around the hearth", we should also pay attention to keeping the doors and windows ventilated at all times to avoid high carbon monoxide concentration leading to poisoning.
In this regard, Wuhan Fire reminds that when using open flames at home, pay attention to stay away from combustibles to avoid sparks splashing and causing fires. Try not to burn charcoal to cook hot pot or tea in a closed room, and be sure to keep the room ventilated and ventilated. The furnace body should be kept away from flammable and explosive materials, and the charcoal fire should be completely extinguished in time after use, and then leave after confirming that there is no danger of re-ignition. Citizens who use gas and gas stoves at home are advised to install carbon monoxide detectors and check and maintain them regularly. Install a fire extinguisher next to an open flame, be familiar with the use of the fire extinguisher, and regularly check the validity period and quality of the fire extinguisher.
