How to survive a sand storm?

A sand storm is one of nature’s most violent phenomena（现象）but not a disaster．（自然灾害）High winds lift dirt particles or sand into air．Sand storms can cause property damage，injuries and even death．So it’s important for you to know about how to keep yourselves safe in a sand storm．

● Be prepared．When you are in a stormy area，carry a mask designed to filter out small particles and bring airtight goggles to protect your eyes．It’s wise to carry a supply of water in case you get stuck in a storm．Wear the clothes that can cover your body to protect you from sandblasting．

● Find shelter．If you are in a house，stay inside．Close all windows and doors，and wait until the storm is over．If you are in a vehicle，roll up the windows and turn off vents that bring outside air in．

● Wear a mask．If you don’t have a mask，wrap a piece of cloth around your nose and mouth．Make it wet or a bit wetter if you have enough water．

● Protect your eyes．Airtight goggles（防风镜）are good．If you don’t have goggles，wrap a piece of cloth tightly around your head to protect your eyes and ears．
