In China, safety education is becoming more and more important now. The last Monday in March is for students to learn it at school. It helps students learn more about what they should do to keep themselves safe. What are the accidents at school? Take a look.
Stampedes (踩踏), earthquakes and fires are the main accidents at school.
A stampede always happens in crowded places. When students around you begin to push, just stand there and try to hold on to something. If you fall down in the crowd, move to one side and protect your head with your hands around.
When earthquakes happen, you can get under a desk quickly and hold on. It will protect you from falling things. lf you are outdoors, find a place away from buildings, trees, and power lines.
When there's a fire, leave the classroom quickly. It's better to put something wet over your mouth and nose. In this way, you won't breathe in smoke. Many people die in a fire, not because of the fire but smoke. It makes them cough and they can't breathe. That's very dangerous! So when you want to get out, you should make yourself close to the floor. Then you can breathe some fresh air.
