Earthquake small knowledge:

1. During the earthquake, most of the experts in our country believe that it is near the earthquake to avoid it, and the rapid evacuation after the earthquake is a better way for emergency shock absorption. The shock absorption should be selected under or next to the object that can cover the body or next to the body, which is easy to form a triangle space. The open room is small, supported, and the room is open and safe.

2. The posture should be taken: to be determined, squat or sit down, and try to curl the body as much as possible to reduce the center of gravity. Grab firm objects such as table legs.

3. Protect the head and neck, eyes, cover your nose and nose. Avoid the flow of people, do not squeeze chaotic, do not lit the fire casually, because there may be flammable and explosive gas in the air.

4. School shock absorption. When class is in class, you must quickly hold your head, close your eyes, and hide under your own desks under the command of the teacher.

5. When the playground or outdoors, you can squat at the original place, protect your head with both hands, and avoid avoiding tall buildings or dangerous objects.

6. After the earthquake, there should be an organized evacuation. Don't jump off the building! Don't stand outside the window! Don't go to the balcony!

7. Family earthquake, the earthquake warning time is short, indoor earthquakes are more realistic, and the triangular space formed after the collapse of indoor houses is often a relatively safe place for people to survive, which can be called a shock -absorbing space. This mainly refers to the space made of large collapse and support. The place where the triangle space is easy to form in the room is: below the pimple, near the solid furniture; the roots of the inner wall, the corner of the wall; the kitchen, toilet, storage room and other small places.

8. Public places have shocks to obey the command of the staff at the scene. Do not panic, do not embrace exit, avoid crowded, avoid flow of people, and avoid being squeezed to the wall or fence. (1) In the theater, gymnasium, etc.: squat or lie under the chairs on the spot; pay attention to avoid suspension of chandeliers, electric fans and other suspensions; use schoolbags and other protective heads; after the earthquake passes, listen to the staff command, organize a organized ground, some organizational grounds Exemptation. (2) In shopping malls, bookstores, exhibitions, subways, etc.: Choose strong counters, products (such as low furniture, etc.) or pillars, as well as inner walls, etc. Open glass doors and windows, glass windows or counters; avoid racks with tall instability or placing heavy objects and fragile products; avoid towering or suspended objects such as billboards, chandeliers.

9. Outdoor earthquakes choose to broaden the ground earthquake: squat or lie down to avoid falling; don't run around, avoid places where there are many people; don't return to the room casually. Avoid tall buildings or structures: buildings, especially buildings with glass curtain walls; crossing streets, overpass bridges; high chimneys and water towers. Avoid dangerous objects, towering or suspension: transformers, electric poles, street lights, etc.; billboards, cranes, etc. Avoid other dangerous places: such as narrow streets; dangerous houses, dangerous walls, bricks, wood, etc.
