Earthquake self-help common sense

1. Indoor emergency

A destructive earthquake takes only 12 seconds on average from the feeling of vibration to the destruction of a building. In this short period of time, you must not panic. If you live in a bungalow, then you can quickly run outside. If you live in a building where you ca n’t get out, you should immediately turn off the gas and the electric gate, extinguish the fire, hide under a sturdy bed, table, or into a room with a small span, such as a bathroom or kitchen, pay attention to protecting your head, To prevent foreign bodies from being injured; cover your mouth and nose with a mask, and lower your body; be careful not to jump off the building, as the saying goes: "Small earthquakes don't need to run, big earthquakes can't run", because people stand during the earthquake Unstable walking makes it extremely dangerous to jump; do not go down stairs, run around, or be crowded with people. These places are prone to collapse and squeeze. According to the investigation results of the Tangshan earthquake damage, the number of casualties caused by jumping or escaping in the six main types of casualties (direct injury and death, suffocation and death, jumping or escaping, improper shelter, return to a dangerous building, rescue or improper care, etc.) In the third place.

2. School shock

1. When you are on the playground or outdoors, you can squat down in place, protect your head with both hands, and pay attention to avoid tall buildings or dangerous objects.

2. Don't go back to the classroom.

3. There should be an organized evacuation after the earthquake.

4. Never jump off the building! Don't stand outside the window! Don't go to the balcony!

In schools, shops, theaters and other places where people gather, they can squat under the desk, counter, row of chairs or the side of the column, the corner of the inner wall, pay attention to the head protection with hands or other things, and avoid the glass doors, windows, chandeliers, fans Do not run around while hanging, etc., otherwise it will cause chaos, squeezing each other and causing casualties. During the rescue of the 1970 Tonghai Earthquake in China, it was found that most of the dead were near the door of the house, indicating that people were fleeing during the earthquake and were buried in collapsed houses before reaching a safe place. They could not struggle with their own strength. Other earthquake examples This is basically the same.

3. Outdoor emergency

When driving a car, grab the handrail and lower your head to avoid falling or bruising; you can lower the center of gravity, hide near the seat, and wait patiently for parking to escape.

People who are outdoors, cover their heads with suitable objects (with both hands), and run to an open place. Pay attention to avoid tall buildings, especially those with glass, as well as chimneys, water towers, billboards, street lights, big cranes, overpasses, and overpasses. Can't hide in the building group and can enter the roadside building, the ground floor is not easy to collapse, but there is a danger of being buried.

People who were in the suburbs during the earthquake should quickly leave the mountain side, the river bank, high-voltage lines, and telephone poles to prevent emergencies such as anti-skid slopes and flooding.

4. Common sense of self-help

If you are buried in the rubble, try to keep calm and try to move the moving objects around you to expand the space. Use bricks, wood, etc. to reinforce and support heavy objects that may fall to prevent aftershocks. If you are indoors, cover your mouth and nose with your hands, clothes, or sleeves to prevent suffocation due to natural gas or gas leaks. It is necessary to preserve physical strength, create living conditions and wait for rescue. Believe in yourself and the party! Stay optimistic and confident!

When retreating, take off your jacket and unfasten the belt with a belt buckle to avoid being caught by obstacles in the middle.

5. Common sense of mutual rescue

When saving people after an earthquake, time is life. Rescuing people should be rescued from the nearest place. This method can save time and reduce casualties. To save the young and middle-aged first, to rescue a young man is equivalent to adding a rescue force; in addition, we must pay attention to save the voice first, and save the easy-to-save first.

When rescuing others, first determine the position of the injured person ’s head to expose the head, quickly remove the dust in the mouth and nose, and then expose the chest and abdomen. If suffocation, artificial respiration should be given in time. People who stay in the dark for a long time should avoid the stimulation of strong light after coming out. People who are hungry for a long time cannot feed too much food at once.

In the early rescue work after the earthquake, most of them were carried by hand digging shoulders. During the process of digging with sharp tools, special care should be taken not to cause dust and debris to fly, causing accidental injuries and suffocation of the rescued. .

Sixth, home earthquake preparation

After the government releases the earthquake forecast, residents must prepare for earthquake prevention at home, formulate a plan for earthquake prevention at home, and check and eliminate hidden dangers of adverse earthquake prevention at home in time.

1. Reasonable placement of furniture and items

Fix tall furniture to prevent falling over and hitting people; the hangings on the wall should be removed to prevent falling and hurting people; clean up the debris, let the doorway and corridor clear; the balcony retaining wall should be cleaned up, remove the flower pots and debris; Keep flammable, explosive and toxic materials in a safe place;

2. Prepare necessary shock-proof items

Prepare a household shockproof bag including food, water, emergency lights, simple medicines, ropes, radios, etc., and put it in a convenient place.

During the earthquake, there were three opportunities to shut down the fire:

First chance at the time of small shaking before the big shaking comes

At the moment when you feel small shaking, immediately turn off the heating stove, gas stove, etc. in use.

The second chance is when the big shaking stops

It is dangerous to turn off the fire when there is a big shake, and the kettle placed on the gas stove or heating stove falls down. It is more reasonable to turn off the fire after the big shake stops.

Third chance after a fire

Even if a fire occurs, it can be extinguished within 1-2 minutes. In order to be able to extinguish the fire quickly, please put the fire extinguisher and fire bucket often near the fire place.
