Heavy rain and floods are wreaking havoc in the middle and lower reaches of the Yangtze River, and Sichuan and Yunnan, where there are many mines, will also usher in a new wave of heavy rain. According to The Paper, Sichuan will usher in two more rounds of heavy rain within five days. As of July 3, floods and waterlogging disasters have affected 19.38 million people in 26 provinces (regions and cities) including Guizhou and Sichuan, with 121 people dead or missing and direct economic losses of 41.64 billion yuan.

The flood season came earlier this year. As early as March 28, heavy rainfall of more than 50 mm occurred in six provinces including Zhejiang, Fujian, Jiangxi and Hunan. In terms of the current comprehensive destructive power, this year's floods have exceeded those of the past few years.

For miners in the flood season, flood prevention is a common topic, but some miners come from the northwest to the southwest and are not familiar with the mining environment in the south. The following content is summarized and provided by industry professionals, authorized by Wu Blockchain, and recommended for collection.

1. Flood prevention and safety knowledge - dealing with rainstorms and flash floods

Before a rainstorm or flood: (1) Avoid activities in low-lying areas or areas threatened by landslides. In early summer every year, check the area in front of and behind your house and pay attention to geological changes nearby to see if there are any signs of danger. (2) Be familiar with the surrounding environment and bring along necessary waterproofing and drainage facilities, such as canvas, woven bags, sand and gravel, wooden boards, and water pumps. Pay attention to the forecasts of the local meteorological and flood control departments. In particular, areas with dense crowds should be promptly evacuated and relocated.

After a rainstorm or flood: (1) When you discover a major sign or a disaster has already occurred, spread the news as soon as possible to attract attention and strive to control the development of the disaster and rescue. (2) In an emergency, keep a cool head, act quickly, and give up decisively. Rainstorms and floods are sudden, rise and fall sharply, and last for a short time. When you find that the river is flooded, you must evacuate quickly and do not hesitate. When the river is flooded during the flood season, do not force your way across the river. Be patient and wait for the river to recede before crossing the river, or take a long detour to cross the river. (3) When a rainstorm or flood occurs, pedestrians should stay away from dangerous areas such as high-voltage lines and electrical equipment when taking shelter from the rain. Turn off your mobile phone during thunderstorms. (4) Provide timely emergency rescue such as artificial respiration to drowning people.

2. Flood prevention and control safety knowledge - take preventive measures when heavy rain comes

(1) When a rainstorm comes, close doors and windows to prevent rain from rushing into the room. If water enters the room, immediately shut down all electrical equipment.

(2) Cut off dangerous outdoor power supplies in low-lying areas.

(3) Do not use underpasses or passages beneath viaducts.

(4) Do not walk in running water. Running water only 15 cm deep can cause a person to fall.

(5) If you find that the water is fast-flowing, turbid, or mixed with mud in mountainous areas, it may be a precursor to a flash flood and you should leave the stream or river.

(6) When driving in heavy rain, you should turn on the rain and fog lights, slow down, pay attention to prevent mountain torrents, and avoid flooded and landslide sections.

(7) Pay attention to the factory's electrical facilities. If any wires fall or water enters electrical equipment, move away immediately and report to the professional power operation and maintenance personnel immediately.

(8) If your residence is likely to be severely flooded, you should evacuate your residence and seek shelter in a safe place.

(9) If you encounter danger, please dial 110 for help.

3. Tips on flood prevention and safety

1. The climate during the flood season is changeable and sudden, and disastrous weather such as thunder and lightning, heavy rain, hail, tornadoes, etc. often occur.

2. Natural disasters such as landslides, collapses, mud-rock flows and flash floods are prone to occur during the flood season.

3. Listen to weather forecasts regularly, pay close attention to weather changes, understand and grasp disaster forecasts, and do a good job of flood prevention and self-protection. Carefully learn about disaster prevention and relief during the flood season and improve your self-protection capabilities.

4. Do not travel or stay in areas prone to flash floods (river and stream banks, beaches, and low-lying areas).

5. Do not go to dangerous areas or dangerous buildings where landslides, collapses, mud-rock flows, etc. are likely to occur.

6. Do not play in the water or swim in streams, rivers, ponds, reservoirs or other water bodies.

7. If you need to cross a stream or river, find a bridge to cross. Do not wade across a pond, stream, or river, and do not risk rushing across a stream or river.

8. Do not go fishing or playing in streams, rivers or other water bodies.

9. When encountering disastrous weather, try not to go out. If you are already out, find a safe area to avoid disaster and protect yourself.

10. Be familiar with the local government’s emergency signals, emergency evacuation routes and locations. When emergency evacuation is required, follow the unified command of the local organizers and evacuate safely in a timely, orderly and timely manner.

11. When you encounter danger on the way, don't panic. You should quickly take measures to avoid danger and save yourself or find ways to ask for help. Don't take risks.

4. Self-rescue methods during floods

1. How to wait for rescue in flood disasters

The occurrence of floods is the result of disaster energy accumulated to a certain level. Therefore, before the flood arrives, people in the flood-stricken areas should use this limited time to make preparations as fully as possible.

If conditions permit, build or raise the dike; if conditions are not available, choose a high place for refuge, such as a roof with a solid foundation, a shed on a tree, or a temporary shelter. Steam and cook food that can be eaten for a few days, slaughter livestock to make cooked food; store clothes and other cold-resistant items in a high place; make a raft, and collect floating materials such as wooden basins and wood blocks to process them into life-saving equipment in case of emergency; waterproof and bundle valuable items that are inconvenient to carry and bury them underground or place them in a high place; tickets, jewelry and other items can be sewn into clothes; prepare medicine, fire and other items; and preserve all usable communication facilities.

2. How to escape when a flood is coming

Residents in flooded areas with a water depth of 0.7m to 2m or where the flood flow rate is too high to survive should take evacuation measures in a timely manner. Since evacuation is mainly a large-scale, organized evacuation, please pay attention to:

(1) Evacuation routes should be planned in advance so that every evacuee knows where the flood will hit first and where it will hit later, so that they can choose the best route and avoid being in a passive situation where the flood will hit them wherever they are.

(2) Check in advance all points in the factory where water is likely to enter, and prepare an appropriate number of sandbags in reasonable locations in advance to block them in time when floods come.

(3) Be familiar with various signs. In areas prone to flooding, the government has built evacuation roads. Generally speaking, such roads should be one-way to reduce traffic congestion and blockage. On those evacuation roads, there are road signs indicating the direction of travel. If the evacuees do not recognize the road signs well and blindly go the wrong way and then turn back, they will collide with other people, causing congestion and unnecessary chaos.

(4) Stay calm. During a flood, refugees are already in a state of panic due to their own suffering and the huge losses caused by the flood. If they are also disturbed by external factors such as rumors, sudden shouting from the refugee team, and the sirens of police cars and ambulances, unnecessary panic and confusion will easily occur.

3. Which are the safer shelters?

Shelters should generally be located in places that are closest to the factory building, have higher terrain, and are more convenient for transportation. They should have water supply and drainage facilities, good sanitary conditions, and good communication and transportation links with the outside world. There are generally two types of shelters in mountainous areas: one is on the levee, but the sanitary conditions there are poor, and there are no water supply and drainage facilities. People just let the flood settle, sprinkle bleach, and drink it directly; in addition, people and animals eat, drink, and excrete here, and domestic garbage accumulates. Over time, it is very easy to get sick. The second is in villages and farmers' homes.
