Matters needing attention in sand lifting

Adverse effects of dusty weather on human beings.

Sand-blowing weather will pollute the environment, and there are dust wrapped in strong winds everywhere. The passing air is turbid, choking nose and squinting, which can make the number of respiratory diseases and lung cancer index soar.

Buried hidden dangers A lot of dust carried by dusty weather blocks the sun, and the weather is gloomy, which leads to the reduction of solar radiation, and the low visibility can last for several hours to more than ten hours. A dark sky can easily make people feel depressed and reduce the efficiency of work and study. In addition, the dusty weather has a great impact on traffic safety, and low visibility leads to frequent traffic accidents, and even leads to the closure of expressway, making it impossible for planes to take off and land normally. In severe cases, it can lead to damage to the glass of cars and trains, and even stop and derail.

take measures

(1) Avoid staying under billboards and old trees. Under the action of strong wind, billboards with unstable installation or ancient trees with unstable foundations are easy to collapse or break, endangering the life safety of pedestrians.

(2) Close the doors and windows in time to reduce going out, especially for the elderly and children. People who have to go outdoors had better wear masks, or protect their eyes, mouth and nose with wet towels and gauze towels, which can effectively reduce dust inhalation, which is very harmful to the body and lungs. Wash your hands and face before eating.

(3) Because of the dry weather, people should drink more water, replenish the lost water in time, and accelerate the discharge of various metabolic wastes in the body, which is very beneficial to skin and health care.

(4) Once you find obvious discomfort, you should go to the hospital in time.

(5) Ride a bike less in windy weather, because riding a bike in a crosswind is likely to be blown down by the gale, causing physical injury.

Medical experts say that dust is the most harmful to the human respiratory system and people should not underestimate it. In particular, the elderly, infants and patients with respiratory allergic diseases with poor resistance should stay indoors, close doors and windows and try to stay away from dust sources.

Medical experts say that allergic diseases, epidemics and infectious diseases may be induced in dusty weather, especially in the case of sandstorms. Under normal circumstances, people's nasal cavity, lungs and other organs have a certain filtering effect on dust, but the dust storm, a disastrous weather phenomenon, brings too much and too dense fine dust, which is very likely to make people with respiratory allergic diseases relapse. Even healthy people, if they inhale dust for a long time, will have uncomfortable symptoms such as cough and asthma, which will lead to the outbreak. In addition, strong winds span thousands of kilometers, blowing germs along the way to downwind areas, which may include some infectious germs and carcinogens.

Medical experts suggest that some people in cities should use wet towels and gauze to protect their eyes and mouths when they have to go outdoors because of their professional needs. In dusty weather, people should drink more water, eat more light food and wash their hands and faces before eating.
