The 7.0-magnitude earthquake that occurred in Lushan County, Ya'an City, Sichuan Province on April 20th is now in “Golden 72 Hours” after the earthquake. During this time, the survival rate of the victims is high, and how safe and scientific the search and rescue are, and After being rescued, how to deal with it? We provide readers with service manuals from the three aspects of “post-earthquake search and rescue”, “self-protection” and “security precautions”.

Self-protected water: At least 3.8 liters of water should be reserved per person per day, and 72 hours for this purpose. It is recommended to buy some bottled water.

Food: Prepare canned or dehydrated foods, powdered milk, and canned fruit juices for 72 hours. Dry cereals, fruits, and dried fruits without salt are good sources of nutrition.

Use the space under the desk, table, bench, or body to cover the internal load-bearing wall as a cover, then grasp firmly with your hands.

No desk or table, cover your head and face with your arms, and lie sideways on the corner between the sofa and the ground.

If you are in bed (if the ceiling does not have a large lamp) when the earthquake occurs, please stay alive. Grab a pillow to protect your head.

Do not park your car under a building, near a tree, over an overpass, or under a wire and cable.

After the earthquake has stopped, the vehicle should proceed with care, pay attention to the damage of roads and bridges, and do not try to cross the damaged bridge.

In the case of ensuring safety, stop as soon as possible and stay in the car.

Tap on the pipe or wall to let rescue workers discover you. Use whistle if possible.

If you are trapped under the rubble, do not firewood or use a lighter.

If you are trapped under the rubble, cover your mouth with a handkerchief or cloth. Do not move around to avoid dust.

Do not use the elevator to escape.

Stay away from building areas, trees, street lights, and wire and cable.

Emergency lights for emergency prevention: Put an emergency light at your bedside, at work, and in your car. Do not use matches or candles after the earthquake unless you can be sure there is no gas leak.

First aid kit: Prepare a first aid kit at home and in the car. At the same time, let your family learn basic basic first aid and artificial respiration courses.

Fire Extinguisher: Fire extinguishers are available in your home and in your car.

Special items: Prepare necessary special items such as medicines, hearing aid batteries, baby products, hygiene items and other items needed by the family.

Clothing: You may not be able to warm up after an earthquake. Take into account warm clothes and sleeping supplies. Make sure everyone at home has a complete set of changing clothes and shoes.

Post-earthquake search 1 Manual search uses high-powered loudspeakers or other probing equipment to shout and give instructions to trapped survivors. Then keep the affected area quiet, and artificial searchers listen carefully and mark areas with sound. Manual search is more accurate than other search methods.

2 Instrument search technology The search personnel mainly use sound waves and vibration monitoring equipment to search the affected area. If necessary, optical fiber equipment, infrared thermal imaging equipment (if conditions permit), or other equipment can also be used for searching.

3 Search and rescue dog search In the initial stage of search and rescue missions, two search and rescue dog teams are generally deployed to participate in search and rescue.
