Why is there always gas poisoning in the cold season?

In winter, on the one hand, because of the strong outdoor wind, on the other hand, because of the indoor heating, people always like to stay indoors, so winter is often the high incidence season of harmful gas poisoning. Gas poisoning is the most common in family life. There are casualties caused by gas poisoning every winter. Autumn and winter are the high incidence of gas poisoning incidents such as liquefied gas and gas. In daily life, we should tighten the string of safety protection, use liquefied gas, gas and natural gas correctly, and guard against leakage and poisoning incidents. Every winter, when people use water heaters to keep warm or take a bath, gas poisoning will happen if they are not careful. Because of the weather, all the windows are closed, which leads to air circulation and gas poisoning. Due to the user's negligence, the valve of the gas bottle was not properly closed, resulting in gas poisoning.

In addition, once the leakage of liquefied gas, coal gas and other gases is found, the doors and windows should be immediately opened for ventilation, evacuated quickly and alerted in time. At the same time, remember to prohibit the use of equipment that is prone to open flames and sparks, such as electric lights, telephones, mobile phones, televisions, gas stoves, flashlights, candles, etc., before ensuring the air circulation in the poisoned environment. To prevent carbon monoxide explosion when the concentration of open flame is too high. Because residents in northern China mainly rely on coal for heating in winter and spring, large areas of smoke and dust are easy to cause pollution sources. With the development of the city, a large number of cars appear, and automobile exhaust is also the main factor to form pollution sources. Due to geographical and environmental factors. For example, Yanbian area belongs to basin climate, and it is easy to form a small-scale closed climate. Some meteorological conditions are also prone to carbon monoxide poisoning, such as low air pressure, high humidity, thick inversion layer and still wind. The poisoning incidents in Yanbian area since the beginning of February, especially 13, are also caused by these factors.
