Three streams of cold air will be "sent" to our country this week
The first of these shares has already begun to have an impact.
Today and tomorrow. Affected by cold air.
Temperatures dropped by 4 to 6 in parts of the central and eastern parts of the country
It is accompanied by northerly winds of force 4 to 5.
Reminder. Everyone is keeping warm from the cold at the same time.
Also be especially vigilant against improper heating.
carbon monoxide poisoning and other incidents.
Identification and prevention methods are attached below).
Affected by the cold air of frequent activities, it is expected that from the 9th to the 12th, there will be continuous snowfall in northwest Xinjiang, and heavy to heavy snowfall and localized heavy snowfall in some areas of Altay and Tacheng. In addition, from the night of the 10th to the 11th, there was light to moderate snow in parts of northeastern Inner Mongolia, Heilongjiang, Jilin and other places.
The public should be aware of the adverse effects of snowfall on roads, icy roads and reduced visibility, and pay attention to travel safety.
It is expected that from the 11th to the 12th of this week (mainly affecting the north to the 14th (affecting the area north of the middle and lower reaches of the Yangtze River), there are still two waves of cold air waiting to be "sent".
This week, three consecutive waves of cold air affected our country, although the overall force is weak, but we still need to pay attention to temperature fluctuations, pay attention to cold and warm. Of course, the premise is: scientific and safe heating methods.
In the past two days, the topic The First Hospital of Zhejiang University received 47 patients with tea poisoning around the stove in half a month and appeared on Weibo hot search. Seeing the cold wind blowing outside the window, many people lit a "red clay stove" indoors with great interest, wanting to warm up while drinking tea through the poetic way of boiling tea around the stove.
However, due to improper ventilation, it has also caused a number of typical carbon monoxide poisoning incidents.
How dangerous is carbon monoxide poisoning?
Carbon monoxide is an invisible "killer" that is colorless and odorless. Carbon monoxide poisoning, commonly known as gas poisoning. In production and life, the incomplete combustion of carbon-containing substances produces carbon monoxide, which enters the body through the respiratory tract and causes poisoning.
Whether it is "around the stove" to cook tea or barbecue, there are potential safety hazards, and everyone must be vigilant. According to experts, carbon monoxide poisoning has a toxic effect on tissue cells throughout the body, and has great damage to the lungs, heart, brain and other organs of the human body, especially the most serious impact on the cerebral cortex. In severe cases, consciousness is impaired, coma, and may even be life-threatening.
Carbon monoxide poisoning and meteorological conditions.
Weather such as lower temperatures, snowfall, and strong winds tend to make everyone close their doors and windows, resulting in poor air circulation. In low-pressure weather, the gas stored in the room cannot be discharged in time. Carbon monoxide meteorological index.
The Carbon Monoxide Poisoning Meteorological Index (COO) is a new meteorological index for the public. The forecast for the meteorological index of carbon monoxide poisoning is issued during the heating period, from November 1 to March 31 of the following year. It is divided into 4 levels, and the meteorological department will provide precautions and protective measures to the public according to different levels.
How can I tell if I am poisoned by carbon monoxide?
Mild poisoning: Poisoned people will feel headache, dizziness, dizziness, and fatigue.
Moderate poisoning: Poisoned patients may have excessive sweating, irritability, unsteady walking, paleness, confusion, and always feel unable to wake up, drowsiness and fatigue.
Severe poisoning: the poisoned person is delirious, trismus, convulsions all over the body, incontinence, cherry red complexion and lips, rapid respiratory pulse, increased blood pressure, irregular heartbeat, and extremely critical patients may continue to be in a deep coma, irregular breathing, blood pressure drops, and may also have a high fever of 40 degrees Celsius.
What to do if you have carbon monoxide poisoning?
If symptoms such as headache, dizziness, nausea, and vomiting occur, ventilate immediately, douse the charcoal fire with water, and evacuate the scene at the same time, and avoid strenuous exercise when evacuating, so as not to increase oxygen consumption. On the premise of ensuring your own safety, you should take the poisoned person around you to a place with fresh air, and if you or others are unconscious, vomiting and unconscious, you should immediately call 120 and seek medical attention as soon as possible.
How to prevent carbon monoxide poisoning in daily life?
In family life, the coal should be burned out, not stuffy, and the coal stove should be equipped with a chimney, especially in the winter when it is cloudy or rainy and snowy. When using a gas water heater, do not close the room, maintain good ventilation, and do not bathe for too long. When using gas or natural gas for cooking, be sure to have someone take care of it to prevent the gas stove from going out due to boiling water or soup overflowing, and a large amount of gas from being discharged into the room. When resting in the motor vehicle, do not use the air conditioner for too long, and open the windows frequently for ventilation. At last.
Elephant hints. Pay attention to personal safety.
Peace and security every day!
