What are the hazards of sandstorms?

1, environmental pollution:

When sandstorms occur, dust and floating dust carried by strong winds are everywhere, and the number of people passing through areas with air turbidity, choking nose and eyes, respiratory tract and other diseases increases. For example,1A serious sandstorm occurred in Jinchang on May 5, 993. The dust content in outdoor air is 10 16 mm/cm3, and the dust content in indoor air is 80 mm/cm3, which is 40 times higher than the national standard for dust content in living quarters.

2. Production and life are affected.

A lot of dust carried by sandstorm weather blocked the sun, and the weather was gloomy, which led to the decrease of solar radiation. A few hours to ten hours of poor visibility can easily make people feel depressed and reduce the efficiency of work and study. In light cases, a large number of livestock can be infected with respiratory and gastrointestinal diseases, and in severe cases, a large number of "spring-deficient" livestock will die, and fertile soil, seeds and seedlings in farmland will be scraped away.

3. Loss of life and property

1On May 5, 1993, a serious sandstorm occurred in Jinchang, Wuwei, Minqin and Baiyin, Gansu Province, which affected 2,535,500 mu of farmland, lost 42,800 trees, caused a direct economic loss of 236 million yuan, killed 85 people and seriously injured 153 people.

On April 12, 2000, serious sandstorms occurred in Yongchang, Jinchang, Wuwei and Minqin. According to incomplete statistics, the direct economic losses in Jinchang and Wuwei alone amounted to15.34 million yuan.

Sandstorm weather should first prevent dust from entering the body and do the following protective work:

1, minimize travel, close doors and windows indoors to avoid dust exposure.

2. When traveling, pay attention to wearing a mask with dustproof and dust filtering functions, and use it correctly to reduce the dust inhaled into the body. In addition, you can choose windproof glasses to protect your eyes. When choosing them, we should pay attention to the good transparency of glasses, which will not hinder the normal observation of road conditions.

3. Pedestrians should not walk or stay under billboards or trees. Don't drive in a hurry, turn on the width lights, fog lights and taillights, slow down the speed, and honk more to warn the front, rear, left and right vehicles. Some small cars, try to reduce parallel driving to prevent being blown off the road by strong winds. Pay attention to avoid big trucks, away from balconies and billboards, and use internal circulation mode for air conditioning.
