Sandstorms are very harmful, in addition to wearing masks, what else should you do when you go home?

When a sandstorm comes, in addition to wearing a mask, you should close the doors and windows when you go home, and only keep the ventilation area. If the sandstorm is too heavy, try to go out as much as possible, close all doors and windows, and be prepared to stock up on water and some supplies to keep life running.

When you go home, you should wash your face well, so as to avoid some dust splashing into your stomach, and then you should also pay attention to not opening the door when all the windows and doors are closed, in this case, to avoid the harm of the sandstorm's mouth.

Because the wind is relatively strong and the weather is relatively dry, it is necessary to replenish enough water to the body when you go home, and at the same time, you must also wash your face and clothes to avoid affecting the hygiene and comfort of your body at home.

Personally, I think that sandstorms are so harmful that when I get home, I must immediately take off my mask, and I must take a shower, wash my hair, and wash all the dust off my body.

When you go home, you should clean up the sand and dust on your body in time, rinse your mouth with water, and clean your ears and nasal passages. At the same time, the clothes should be cleaned to reduce the residue of harmful substances such as bacteria.

After returning home. You should wash your face in time, clean your nasal passages with water, the dust weather is relatively dry, you should drink more water and eat more fruits. Patients with respiratory illnesses minimize outdoor activities.

After returning home, you should wash your nose with a nasal aspirator, wash your hair and take a shower to remove sand and dust on your body, and drink more water to rinse foreign bodies in your mouth to avoid damage to your body caused by sand and dust.

You should also wash your hands and disinfect them promptly when you get home. A change of clothes. And there are bad weather conditions, so it's best not to go out.

When you get home, you should take off your coat and wash it in time. Because the sand and dust will float on the surface of the coat, it is still quite dirty.

Of course, it can prevent dust and sand. But I don't think it's necessary to bring it, why? The person itself breathes through the nose and then filters through the lungs. In places that are not obvious in Shacheng, there is no need to wear a mask.

Masks are a kind of hygiene products, generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances, made of gauze or paper and other materials.

Masks have a certain filtering effect on the air entering the lungs, and wearing a mask has a very good effect when respiratory infections are prevalent and when working in polluted environments such as dust. Masks can be divided into air-filtering masks and air-supplied masks.

On January 14, 2021, the press office held a press conference to introduce that China exported 224.2 billion masks in 2020. In February and November, the State Administration for Market Regulation and other four departments jointly deployed and redeployed and strengthened the in-depth promotion of mask quality supervision.

News on February 11, 2021. In order to ensure that the people spend a happy, peaceful, healthy and safe Spring Festival.

On the eve of the Spring Festival, the State Administration for Market Regulation, the Ministry of Industry and Information Technology, the State-owned Assets Supervision and Administration Commission and the State Food and Drug Administration jointly issued a document to further promote the quality supervision of masks and redeploy and strengthen them, requiring all localities to adhere to both supervision and service, strengthen the control of production sources, pay attention to supervision and inspection in the field of circulation, and crack down on illegal acts such as the production and sale of counterfeit and shoddy masks, and effectively safeguard the rights and interests of consumers; Strengthen the quality of masks, give play to the leading role of brands, and promote the improvement of mask quality.

The four departments require all localities to attach great importance to it, earnestly enhance their sense of responsibility and mission, take effective measures to provide the people with epidemic prevention supplies and safety guarantees, and serve to promote the overall situation of epidemic prevention and control and economic and social development.

The mask can only prevent sand from entering the mouth, not from sandstorms.

It prevents some sand and dust particles from entering our trachea.

Dust storms are filled with very small particles in the air, which can cause a variety of respiratory diseases when inhaled into the lungs.

Endangering human health.

When people are exposed to sand and dust, dust containing various toxic chemicals and germs can enter the mouth, nose, eyes and ears through layers of protection.

If the dust containing a large amount of harmful substances is not cleaned up in time, it will cause damage to these organs or germs will use these organs as an entry point to cause various diseases. High concentrations of sand and dust in the atmosphere can easily cause respiratory diseases, such as aeolian sand pneumoconiosis, which is an endemic disease caused by severe atmospheric sand dust in arid and semi-arid environments.

Sandstorm hazards.

1. Environmental pollution.

When there is a sandstorm, the sand and gravel and floating dust wrapped in the wind are everywhere, and the air in all the areas passed through is turbid, the nose is foggy, and the number of respiratory diseases and other diseases increases. For example, during the severe sandstorm that occurred in Jinchang City on May 5, 1993, the observed outdoor air dust content was 1,016 millimeters cubic centimeters, and the indoor air was 80 millimeters cubic centimeters, which exceeded the national standard for air dust content in living areas by 40 times.

2. Production and life are affected.

The large amount of sand and dust carried by sandstorm weather covers the sun and shades the sun, and the weather is gloomy, resulting in a decrease in solar radiation, and poor visibility for a few hours to more than ten hours, which is easy to make people feel dull and reduce the efficiency of work and study. In severe cases, it can cause a large number of livestock to suffer from respiratory and gastrointestinal diseases, and in severe cases, it will lead to the death of a large number of "spring shortage" livestock, and scrape away the fertile soil, seeds and seedlings of farmland.

Dust storms can also aggravate the wind erosion and desertification of the surface soil, covering the leaf surface of plants with thick sand and dust, affecting normal photosynthesis and reducing crop yields. The sandstorm also caused the temperature to drop sharply, the sky was like a parasol, and the ground became dark and cold in the shadows.

3. Loss of life and property.

On May 5, 1993, a strong sandstorm occurred in Jinchang City, Wuwei City, Wuwei Minqin County, ** City and other cities in Gansu Province, affecting 10,000 acres of farmland and losing 10,000 trees, causing direct economic losses of 100 million yuan, killing 85 people and seriously injuring 153 people. On April 12, 2000, Yongchang, Jinchang, Wuwei, Minqin and other cities suffered severe sandstorms, and according to incomplete statistics, the direct economic losses of Jinchang and Wuwei alone amounted to 15.34 million yuan.

In the face of sandstorms, you should try to minimize going out, and try to wear masks and goggles when going out to avoid damage to the respiratory tract and eyes caused by sandstorms. When cycling, slow down and stay away from trees and billboards to avoid getting smashed. At home, try to avoid opening the window frequently, and you can also use adhesive strips to paste a rice shape on the glass to avoid glass breaking and hurting people.

Drink plenty of water and eat more light food in your diet.

Sandstorm DefinitionSandstorm refers to a weather phenomenon in which strong winds blow dust and sand on the ground, making the air very turbid, and the horizontal visibility is less than 1 km. Sand and dust storm is a weather phenomenon in wind erosion desertification, and its formation is affected by both natural factors and human activities. Natural factors include high winds, reduced precipitation, and their sources of sand.

Human activity factors refer to the increase in the frequency of sandstorm outbreaks caused by the destruction of vegetation by humans in the process of economic development.

Sandstorm weather mainly occurs in winter and spring, which is due to the semi-arid and arid areas in winter and spring with little precipitation, the surface is extremely dry and loose, and the wind erosion resistance is very weak.

Sandstorms are coming, air pollution is serious, try to go out as many times as possible, and be sure to wear a mask if you go out. Drink plenty of water and don't open the windows at home. Take care of your eyes when you go out. Do a good job of cleaning when you go out and get home.

The 5-4-1 highlights the area covered by the defense, and the 5 defenders ensure the hardness and combat effectiveness of the defense in the middle. At the same time, the two wingers in the midfield are more involved in the task of assisting the defenders and giving full play to the defensive strength. In general, teams in this formation have almost given up attacking.

Fence down and small losses are the tactical guiding ideology of its head coach. Prevention is better than **. In windy, dry and dusty weather, bacteria, viruses, mycoplasma and other microorganisms are active and easy to spread, which can easily induce pharyngitis, nosebleeds, dry eyes, keratitis, tracheitis, asthma, etc.

Throat lozenges are usually used to keep the throat cool and comfortable delicious; Apply eye drops several times to avoid dry eyes; For nosebleeds, you can often put a few drops of dry oil around your nostrils to keep your nasal passages moist and prevent capillary rupture and bleeding.

This period of small friends who live in the north is a headache, because they care about and there is a large-scale sandstorm in the north。The dust weather also brings a lot of inconvenience to people's travel, because they have to go to work because of work, and people will wear masks when they are on the road. What kind of mask to wear is also very entangled, and they don't know if ordinary masks can play a protective role.

In fact, ordinary masks have no effect, and when you go out in dusty weather, you must wear a mask to reduce the damage caused by wind and sand to the respiratory system. <>

Sandstorm weather in the northDue to the large amount of floating dust and inhalable particles in the weather, it is recommended that everyone wear a protective mask of N95 and above when going out。If you wear a mask with an ordinary mouth, these pollutants will enter the person's body through the mouth and cause diseases of the respiratory system. If you don't have an N95 at home, you can use a medical protective mask.

In dusty weather, members of the public should reduce travel and stay at home as much as possible. Tighten the doors and windows and wait for the dusty weather to pass before opening the windows for ventilation. <>

Elderly people and children with respiratory allergies should stay home and reduce outdoor activities. People should not ride bicycles when they go out, cycling is dangerous, try to wear brightly colored clothes, this will reduce traffic accidents. <>

How do I wear a mask? In dusty weather, it is also important to pay attention to the matching mask, and distinguish the front and back of the mask and the upper and lower sections when wearing. It filters most of the bacteria and particles on the front, and is skin-friendly on the back.

If the mask is reversed, it will not only damage**, but also reduce the protective ability. The mask bought on the market is equipped with a nose clip to make the mask fit more closely to the face without leaving gaps, so don't turn it upside down when wearing it. If it creates a lot of gaps, then it will have no effect when you wear it.

Wear a protective mask of N95 or above in dusty weather.

During the daily protection period of the epidemic, ordinary medical masks (i.e., medical nursing masks) or medical surgical masks are generally worn to go out, but in dust weather, the protection of these masks is often insufficient, and after the occurrence of dust weather, the National Health Commission issued health protection tips in a timely manner, pointing out that it is advisable to wear N95 and above protective masks in dust weather.

Among them, N95 masks, also known as N95 respirators, are made in accordance with the standards set by the American Institute of Safety and Health, and the efficiency of filtering particulate matter reaches more than 95%. Among them, n stands not resistant to oil, which can be used to protect non-oily suspended particles; 95 means that the filtration efficiency is greater than 95%.

Precautions for sand and dust weather:

1. Pay attention to closing doors and windows. Close doors and windows in time, and if there are gaps, you can stuff some filler to reduce the entry of sand and dust.

2. Try to go out as much as possible. If you really need to go out, you need to be protected from wind and sand. Wear protective equipment such as masks and goggles.

Take back items that are susceptible to wind and sand, such as clothes, bonsai, and flower pots from balconies or outdoors to dry, in advance. and move indoors or sheltered from the wind when touching the Kai. Guaranteed cleanliness and safety.

5. The weather is dry and dusty, and the indoor humidity is relatively low. It can be moderately sprinkled to increase air humidity; You can also use mopping and other methods to increase the air humidity of laughing oaks.
