What should I do if I receive the warning information of sandstorm?

When the sandstorm emergency science popularization receives the sandstorm warning information, if it receives the yellow sandstorm warning signal (sandstorm weather may occur within 24 hours (visibility is less than 1000m) or sandstorm weather has appeared and may continue. ), be prepared for wind and sand prevention, close the doors and windows at home in time, and pay attention to carrying dust-proof articles such as masks and scarves when going out to avoid dust damage to eyes and respiratory tract. Then do a good job of sealing precision instruments, and take good care of temporary structures such as coamings that are easily blown by the wind. Then properly place outdoor items that are easily affected by sandstorms.

If you receive the orange warning signal of strong sandstorm (strong sandstorm weather may occur within 6 hours (visibility is less than 50 meters), or strong sandstorm weather may occur and may continue), cover your head with gauze towels to protect pedestrians from sandstorms and ensure a good vision. Then pay attention to traffic safety and avoid riding bicycles as much as possible. When it is windy, don't stay on billboards, temporary structures and ancient trees. Drivers who go out should pay attention to the changes of sandstorms and drive carefully. In the airport high-speed ferry terminal, we should pay attention to traffic safety and take effective measures to ensure safety. Then there is the yellow warning signal of sandstorm.

If you receive a particularly strong sandstorm in red warning signal (it may appear within 6 hours (visibility is less than 50 meters), or it has already appeared and may continue. ), our staff should. Stay in a windproof and safe place, try not to do outdoor activities, postpone going to school or leaving school until the end of the special sandstorm. Relevant emergency departments and rescue units should be ready to start the emergency plan at any time. Airports in areas affected by particularly strong sandstorms should suspend the take-off and landing of aircraft, highways and ferries should be temporarily closed or other orange warning signals for sandstorms should be suspended.

We will anticipate the sandstorm before it comes, so we will take protective measures in places where sandstorms often occur:

1. Strengthen environmental protection and raise it to the height of legal system.

2. Restore vegetation, strengthen biological protection system and prevent sandstorms. Protect and restore forest and grass vegetation according to law, prevent further expansion of land desertification, and minimize dust sources.

3. According to the local conditions in different regions, formulate disaster prevention, disaster prevention and relief plans, actively promote various disaster reduction technologies, and build model projects, gradually promote them from point to area, and further improve the regional comprehensive defense system.

4. Strengthen the popular science propaganda on the relationship between the occurrence and harm of sandstorms and human activities, and let people realize that once the living environment is destroyed, it will be difficult to recover, which will not only aggravate natural disasters such as sandstorms, but also form a vicious circle, and people should consciously protect their living environment.

5. Plant plants suitable for growing in desert arid areas, such as Hippophae rhamnoides, to form a ground cover plant layer, thus improving the ground cover environment, fixing the soil, reducing the wind speed, increasing the air humidity and improving the microclimate environment.

6. Planting native low shrubs and small trees on the edge of desert to improve vegetation distribution.
