Common disaster weather and preventive measures

The higher the frequency of meteorological disasters, the greater and more serious the losses, which are regarded as natural disasters. Disaster weather, if preventive measures can be taken in time, will be able to minimize losses and mitigate meteorological disasters.

A rainstorm is a heavy rainstorm in a certain period of time. If the hourly rainfall 16 mm or 30 mm, or the 24-hour rainfall 12 mm, it is also called rainstorm.

Then click on the rainstorm, what should we do? How to resist the danger of the storm? Do the following seven preventive work:

1, in cities, especially people living in low-lying courtyards, bungalows or basements, cut off the power supply first to prevent electric shock. Power sockets, switches, etc. It should be moved to a safe place more than one meter above the ground. Outdoor water pours into the house, cut off the power supply to prevent electric shock from hurting people. In case of violent attack, residents can take "encirclement" measures, such as jigsaw puzzle walls, door flaps and protection with small pumps.

2. In case of heavy rain, pedestrians on the street should immediately take shelter indoors, do not stay under tall buildings, and do not block or stay on large billboards to avoid being smashed. When walking in stagnant water, pay attention to observation to prevent falling into manholes or pits.

3. Urban rainstorm is easy to surface water, which seriously causes river water to invade and flood roads, so that vehicles turn off and pedestrians get off in time to go to higher places. In this case, the driver should avoid water accumulation.

4. Don't throw garbage and other sundries into the sewer at ordinary times to prevent water damage caused by blockage and rainstorm. This river is an urban drainage channel. Dumping garbage and waste is prohibited to prevent congestion.

If it is in the wild, there will be heavy rain in a short time and the river will rise sharply, so it will not stay in the river. If this happens, it should be moved to hillsides, highlands and other places. Proceed in an organized way according to the predetermined route. If you are surrounded by floods, use boats, rafts, door panels, wooden beds and water transfer as much as possible. If the flood comes too fast, you should climb the roof immediately and build a tall one. Don't spread it by swimming.

6. In mountainous areas, even if it rains heavily, it is prone to flash floods and avoid crossing the river. During the rainstorm, do not leave long mountains with basic osteoporosis to prevent flash floods from washing away, but also pay attention to prevent landslides, rolling stones and mudslides.

7. When it is found that the toppled electric tower and wires are drooping or broken, stay away from danger and do not touch or get close to them to prevent electric shock.

The reason for the breach is the flood disaster. The flood is a watershed. The endogenous concentration of rainstorm or long-term rainfall, the inflow and river runoff exceed its flood discharge capacity and overflow both sides of the dam.

In Zhejiang Province, floods mainly occur from June to September, with the rainy season from mid-June to mid-July and the typhoon season from mid-July to September. Floods are prone to occur, causing farmland to be flooded, villages to be washed away, houses to collapse, property losses and even casualties. Before the flood came,

Try to be prepared accordingly.

1, according to the flood information provided by local TV stations, radio stations and other media, combined with their own location and conditions, choose the best route to evacuate calmly and avoid a passive situation. "People don't go into the water."

2, recognize the road signs, clear evacuation route and destination, so as not to panic and go the wrong way.

3, self-protection measures:

Fast food or cooked food is enough, food for a few days, prepare enough drinking water and daily necessities.

—— Rolling rafts and bamboo rafts, collecting wooden pots and wood, suitable for large foam floating objects, and processing them into life-saving equipment for emergency use.

OE is inconvenient to carry valuables. Buried height, tickets, jewelry and other small valuables can be sewn into clothes for waterproof binding.

-Save the communication equipment.

Flood rescue:

1, when the flood comes, transfer people to the nearest hillsides, highlands, buildings, Taiwan Province Province and other places to escape, or immediately climb the roof to build tall buildings, trees, fences and accommodation.

2. If the flood continues to rise, it is difficult for temporary shelters to protect themselves, so we must make full use of them and make preparations for life-saving escape, or quickly find some doors, tables and chairs, wooden beds and large foam floats to tie them into rafts to escape.

3. If you are trapped by the flood, try to get in touch with the flood control department of the local government as soon as possible, report the location and danger, and actively seek rescue.

Attention: Don't swim to escape, don't climb electrified telephone poles and iron towers, and don't climb to the mud house on the roof.

4. People who are already in the flood must try their best to catch fixed or floating things and look for opportunities to escape.

5. When the electric tower is tilted or the wires are broken and drooping, you must escape as soon as possible to prevent direct electric shock or electric shock due to "step voltage" on the ground.

6. After the flood, health and epidemic prevention should be done well to prevent the spread of the epidemic.

The most common rainstorm causes flash floods, which usually refers to the sharp decline of floods and the surge of floods, forming mountain gullies, accompanied by landslides, collapses and mudslides. The explosion of structural facilities caused flash floods. Flash floods and disasters caused by floods include casualties, property losses, infrastructure damage, resource damage and environmental damage. Floods, mudslides, landslides and floods.

How to get out of danger quickly when encountering mountain torrents?

Residents living in areas prone to mountain torrents or gullies, canyons and streams must be on high alert whenever it rains heavily in autumn, especially at night. If there is any abnormality, immediately organize personnel to evacuate the site quickly, choose a safe place nearby, try to contact with the outside world, and do the next rescue work well. Don't delay the escape time by leaving things or saving property, causing unnecessary casualties.

What if there is a sudden flash flood?

1, be sure to stay calm, quickly judge the surrounding environment, and move to the mountains or higher places as soon as possible to avoid such a moment. You should choose a relatively safe place to avoid the flood.

2. When flash floods break out, don't run along the direction of the flood diversion channel, but flee to both sides quickly.

3, flash floods, don't wade across the river easily.

If mountain torrents are trapped in the mountains, you should contact the flood control department of the local government in time for help.
