Matters needing attention when the cold wave comes

Preventive measures for the coming of cold wave. When a cold wave appears, it will be accompanied by windy weather. The wind is very cold, and the maximum can reach about 8. The duration of cold wave and gale is relatively long, and the longest time is about 100 day. Preventive measures for the coming of cold wave.

Precautions for cold wave attack 1 Once receiving the cold wave warning issued by the meteorological department, the public should pay attention to taking corresponding defensive measures to realize "two plus three defenses".

Add clothes: when the temperature drops suddenly, pay attention to add clothes to keep warm, especially on your hands and face.

Reinforcement: Close doors and windows, fasten outdoor structures and prevent falling objects.

Disease prevention: the elderly, children, cardiovascular patients, asthma patients and other people who are sensitive to temperature changes should try not to go out.

Non-slip: The road surface is slippery in rainy and snowy weather. Be careful when going out.

Prevention of gas poisoning: families who use coal stoves for heating should be careful of gas poisoning.

Remind everyone that there is no small matter when the cold wave strikes, and there is no children's game to keep warm and prevent diseases; ; Don't be careless when traveling. Health and safety first.

Matters needing attention

1, pay attention to ventilation. When heating equipment such as coal stove and charcoal fire is used indoors, doors and windows should not be completely sealed with plastic film, and a certain gap should be left to make indoor air circulate and avoid carbon monoxide accumulation. Ventilate the doors and windows frequently to keep the indoor air fresh.

2. Choose a regular heating tool. The heating coal stove should be equipped with chimneys, and the stove should be purchased from formal channels. The joint of the chimney should be firmly connected (the thick end of the chimney faces the coal stove), and the chimney structure should be kept tight and well ventilated to prevent the leakage and backflow of flue gas and keep it smooth. Direct-row water heaters and flue-type water heaters prohibited from production and sale by the state shall not be used.

3. Check regularly. Install and use heating equipment such as coal stove and charcoal fire correctly. Install the water heater in an outdoor ventilated place as far as possible. Don't close the bathroom doors and windows when taking a shower, and don't take a long shower.

4. Stay away from dangerous goods. Coal, fire and other heating equipment should be far away from flammable, explosive and volatile toxic substances.

Preventive measures for the coming of cold wave Two benefits of cold wave

1. With the increase of latitude, the solar radiation energy received by the earth gradually weakens, so the earth forms tropical, temperate and cold zones. The cold wave injects a lot of cold air into tropical areas, which makes large-scale heat exchange on the ground, which is very helpful to maintain the ecological balance of nature and maintain the lush species.

2. Whenever the cold wave hits the south, it will often bring a wide range of rain and snow weather, alleviate the winter drought and benefit crops.

3. The low temperature brought by the cold wave is the most effective natural "insecticide" at present, which can kill a large number of pests and germs lurking in the soil for the winter, or inhibit their reproduction and reduce pests and diseases in the coming year.

4. Cold wave can also bring wind resources, and the power generation efficiency in cold wave period is generally 1.5 times that in normal times.

Hazards of cold wave:

First of all, when a cold wave appears, it will be accompanied by windy weather. The wind is very cold, and the maximum can reach about 8. The affected areas are northwest, northeast and north China. Cold wave and strong wind last for a long time, the longest is about 100 days. The Qinghai-Tibet Plateau is the region that has been affected for the longest time. The appearance of cold wave and strong wind will cause dusty weather and affect air quality. In addition, the cold windy weather will endanger the growth and yield of crops. Livestock mortality will increase in the cold wind.

Secondly, the cold wave will cause large-scale freezing damage, which not only has an impact on crops and animal husbandry, but also has a serious impact on road traffic and maritime transportation. In the cold wave, crops are seriously damaged, livestock and poultry will freeze to death, roads will freeze and snow, rivers will freeze, and so on, which will cause huge economic losses to people. Among them, wheat is the most seriously damaged in freezing injury, winter wheat seedlings will die in freezing injury, and the yield will be greatly reduced.

Finally, the cold wave will lead to a severe snowstorm. Although it says "good years and good snow", it must rain to a certain extent. If it doesn't snow so hard, animals and plants can't stand the cold at all and will freeze to death. How can we have a good harvest? In addition, if the snow is too thick, the department staff can't clear it in time, which will seriously affect traffic, roads and railways. Avalanches will also occur in some areas, causing major accidents.

Precautions for Cold Wave Attack 3 Professional Anti-freezing Raiders:

1. "Wear clothes and hats": For water-using facilities such as water pipes and faucets exposed outdoors, cotton and linen fabrics can be used for insulation, and the water meters in the water meter well box can be covered with waste clothes for insulation.

2. "Close the windows to prevent cold": In cold weather, especially at night, all rooms facing north, such as balconies, kitchens, bathrooms and corridors, should be closed tightly to ensure that the indoor and corridor temperatures are above zero.

3. "Dripping water into a line": In cold weather, if the temperature is below minus 3℃, you can slightly unscrew the faucet at night to make the dripping water into a line to ensure the running water in the pipe and prevent freezing at night.

4. "Evacuation facilities": houses that have been uninhabited for a long time, close doors and windows and water meter valves, turn on the faucet at home, and empty water pipes. If the solar water heater is installed outdoors, the water pipes should be equipped with anti-freezing and drainage devices. When the temperature continues to be lower than minus 3℃, drain water to prevent freezing.

The cold wave is coming, pay attention to these problems!

1, the temperature drops suddenly, which diseases are high?

The sudden drop of temperature in winter has the greatest and most obvious impact on the elderly, pregnant women, infants, patients with chronic diseases such as cardiovascular and cerebrovascular diseases and respiratory diseases, and people who work outdoors for a long time.

In winter, the daily temperature difference is large, and the weather is cold in the morning and evening. Morning is also often called "devil's time" for cardiovascular and cerebrovascular diseases. At this time, the temperature is low, but after falling asleep at night, there is no water and the blood becomes sticky. Low temperature is easy to cause the attack of cardiovascular and cerebrovascular diseases.

2. How to prevent the outdoor faucet pipeline from freezing at home?

Note that this cold wave is real. These two days, before the cold wave comes, please do one thing well and "put on clothes" for the outdoor faucet, water meter and water pipe at home! Whether it's an old sweater, an old T-shirt or an old cloth, it's best to wrap it in a plastic bag just in case. If possible, it is also excellent to stick a warm baby on the water pipe!
