What weather conditions are prone to gas poisoning?

1. First of all, under the meteorological conditions of slow air flow, gas poisoning accidents are prone to occur when the temperature is generally low, the daily temperature difference is small, there is no wind or breeze, and the air humidity is high. Under such meteorological conditions, the carbon monoxide produced indoors is not easy to spread out, and sometimes there is a phenomenon of pouring smoke indoors, which is easy to cause gas poisoning.

2. Secondly, the influence of wind direction can not be ignored. When the south wind blows, the air pressure in the south is higher than that in the mainland, and the air pressure in the north is lower than that in the mainland, which is just the opposite when the north wind blows. If the chimney of the coal stove extends to the south, when the south wind blows, because of the air pressure difference between indoor and outdoor, it will form inverted smoke; If the chimney sticks out to the north, the north wind will blow and form inverted smoke. Therefore, when the south wind blows, the south window should be opened, and when the north wind blows, the north window should be opened, which can reduce the pressure difference, make the flue gas unimpeded and avoid gas poisoning.

3. In addition, when encountering strong winds, cold waves and smog weather, carbon monoxide poisoning incidents will also increase, which has no obvious relationship with air humidity, precipitation and wind speed. When the weather changes dramatically, the temperature drops, or it snows and blows, people naturally think of closing the window, which can keep the room warm and the temperature will not drop quickly. However, if the living room doors and windows are closed, there is no ventilation at all, the coal stove gas flue is blocked, and the exhaust is not smooth, carbon monoxide poisoning is prone to occur.
