Due to the dusty weather, 400 flights at two major airports in Beijing were cancelled. What are the precautions for traveling in dusty weather?

In recent days, many cities in the north have been affected by sandstorm weather, and many airports have cancelled flights because of sandstorm weather. Two major airports in Beijing also cancelled 400 flights due to sandstorms. It is said that this sandstorm weather is the strongest in recent ten years. Although good achievements have been made in environmental control in recent years, the dusty weather in many places has obviously decreased, especially in North China. It's windy in spring, what should I pay attention to when going out in dusty weather?

People with respiratory diseases and cardiovascular diseases, the elderly, infants and pregnant women should try to avoid traveling in dusty weather. There will be fine dust particles and pollutants in the air in dusty weather, which can enter the human body through the respiratory tract. People with sensitive constitution can cause various respiratory diseases, such as chronic cough, shortness of breath, chest tightness and chest pain. If the patient feels unwell, he should seek medical advice promptly. People who are outdoors should take personal protective measures.

If you need to go out in dusty weather, you must pay attention to personal protection and wear disposable medical masks to avoid morning injuries caused by wind and sand entering the respiratory tract through the nose and mouth. It's best to wear windproof eyes, which are exposed, and wind and sand can easily enter the eyes. Do not rub directly with your hands, but rinse with clean tap water or eye drops as soon as possible. If you still feel uncomfortable, go to the hospital in time. In addition, wearing a windproof hat or wrapping your face with a scarf can also play a dustproof role.

When the vehicle is driving, turn on the width light, tail light and fog light, control the speed, and sound the horn at the intersection to signal the front and rear vehicles. Pedestrians should walk on the sidewalk outdoors, and don't walk or stay under trees, billboards or tall buildings. Bicycles or electric cars can ride with the wind or against the wind in strong winds, but they must not ride in crosswinds, which may be blown down by gusts and cause injuries. When walking or cycling, try not to take the passage between tall buildings, which is easy to form a narrow tube effect, and the wind will increase when passing through the passage, which will cause danger to nutrition.
