China has been hit by the strongest dust storm(沙尘暴) in nearly 10 years. Beijing, the capital city, was affected(影响) by the dust storm recently. We even can’t see each other from less than 1000 meters in most areas. Dust storms appear when strong wind blows sand and dirt from a dry ground. Strong dust storms may cause deaths, so you should know how to protect yourself from dust storms when you meet them.
Be careful of dust storm warnings
Dust storms very probably happen on hot summer days, and it’s not safe for people to travel during this period. So you should listen to the local TV or radio before traveling, and consider changing or giving up your trip if dust storms are predicted(预测).
Be prepared
If you are in a place where storms happen often, carry a mask(面具) to keep dust and dirt away from your face, and a pair of glasses and a scarf to protect your eyes.
Stay inside
Do not move around when a dust storm comes, as you will not be able to see hidden(隐藏的) dangers. So if you’re in a house, don’t go out and just stay inside.
Protect yourself from flying objects
Cover your body as much as possible in a dust storm. A strong wind of dust storms can carry heavy objects, so you should try to stay low, and close to the ground, and protect your head with your arms or a backpack.
