Meteorological Disasters
Lightning defense
Lightning is a phenomenon of cloud discharge accompanied by lightning and thunder.
Defenses:
●Should be kept indoors, and doors and windows should be closed; People who work outdoors should take refuge in the building.
● Do not touch antennas, water pipes, barbed wire, metal doors and windows, building exterior walls, and stay away from live equipment such as wires or other similar metal devices.
● Avoid using telephones and cordless phones.
● Do not swim or engage in other water sports, do not play outdoor ball games, climbing, riding and other sports, leave the water and other open fields, and find a place with lightning protection facilities to take shelter.
● Do not stand on the top of a mountain, the roof of a building or other protruding objects, and do not approach objects with high electrical conductivity.
●When it is impossible to hide in a building with lightning protection facilities in the wilderness, stay away from trees, telephone poles, masts, and other sharp objects.
●It is not advisable to drive or ride a vehicle.
Gale defense
▲Try to go out as much as possible, ride less bicycles when you must go out, and do not stay under billboards and temporary buildings to avoid the wind.
▲If you are driving, you should drive into an underground parking lot or a hidden place.
▲ In the room, you should carefully close the window, paste a rice-shaped tape on the window glass to prevent the glass from breaking, stay away from the window, and avoid strong winds sweeping the sand and stones to break the glass and hurt people.
▲In public places, evacuate to designated places.
▲Agricultural production facilities should be strengthened in time, and mature crops should be harvested as soon as possible.
Rainstorm defense
Heavy rain refers to the precipitation of 50-99.9 mm in 24 hours, the heavy rain in 24 hours in 100-249.9 mm, and the rainfall of more than 250 mm in 24 hours is called extremely heavy rain.
Defenses:
● In case of stagnant water, the car will detour. When the driver is driving, in the event of a sudden rainstorm, beware of the water on the road or under the overpass is too deep, try to detour, and do not force through.
● Walk in the water and avoid well pits. When traveling in a heavy rainstorm caused by a large area of waterlogging, especially children, women, and the elderly should pay attention to the relevant warning signs around them, pay attention to the road surface, and prevent them from falling into manholes, pits, ditches, etc.
●Observe more to prevent electric shock. The rainstorm hit and I was caught off guard. Remember to pay attention to the observation and stay away from electrical wiring, electrical appliances and other facilities to prevent casualties caused by electricity leakage.
●Build a ridge to prevent waterlogging. In order to prevent rainwater from entering the room during heavy rainfall, residents can take appropriate measures to keep them out by placing water baffles, piling up soil or other effective measures according to local conditions.
When the rainstorm comes, close the doors and windows to prevent the rain from entering the house, and turn off the power, gas and other equipment immediately once the water enters.
Cut off the outdoor power supply in low-lying areas with hazards.
Do not walk in running water, as 15 centimeters of water can cause you to fall.
If you find rapid, turbid and muddy water in mountainous areas, it may be a precursor to flash floods, and you should leave the stream or river.
When driving in a rainstorm, turn on the rain and fog lights, slow down, pay attention to prevent flash floods, and avoid stagnant water and landslides.
Pay attention to the electrical facilities on the street, if there is a slipping power line, stay away immediately and report it to the power department immediately.
If there is a risk of severe flooding, evacuate the residence and take shelter in a safe place.
Flood defense
How to prepare for and save yourself in the event of a flood:
1. Be sure to stay calm, quickly judge your surroundings, move to a mountain or higher place as soon as possible, if you can't avoid it for a while, you should choose a relatively safe place to avoid flooding.
2. Recognize the road signs, clarify the evacuation route and destination, and avoid taking the wrong road due to panic.
3. Prepare enough instant food or steamed food for a few days, and prepare enough drinking water and daily necessities. When the flood comes, people who do not have time to move should quickly move to the nearest hillside, the upper floor of a well-structured building, and high ground.
4. When the flood comes, the people in the mud house have no time to move, they should quickly find some floating materials such as door panels, tables and chairs, wooden beds, and large pieces of styrofoam to make a raft to escape. Do not swim or climb onto rooftops.
5. Before the flood comes, bury the valuables that are inconvenient to carry in the ground after waterproofing and bundling.
6. If you are surrounded by floodwater, try to get in touch with the local government or department as soon as possible. Report your location and danger and actively seek rescue.
7. Do not swim to escape, do not climb live poles and towers, and stay away from inclined poles and broken wires.
8. If you have been caught in a flood, be sure to hold on to something fixed or floatable as much as possible and look for an opportunity to escape.
Geological Hazards
1. What is a landslide or collapse?
Landslide refers to the natural geological phenomenon that the rock mass or soil mass on the slope slides down the slope in whole or in part along a certain weak surface or weak zone under the influence of natural environmental conditions and human engineering activities, also known as ground slide or hill walking.
Avalanche refers to the geological phenomenon in which the rock and soil mass on a steep slope suddenly detached from the parent body under the action of gravity, collapses, rolls, and accumulates at the foot of the slope (or valley).
2. What are the precursors of landslides and collapses?
Transverse and longitudinal radial cracks appeared at the front edge of the landslide, and the soil at the front edge was uplifted. The cracks at the trailing edge of the landslide body are sharply lengthened and widened, new cracks are constantly generated, the rear part of the landslide body is rapidly lowered, and the surrounding rock and soil masses are relaxed and small-scale collapses. The rock and soil mass in the sliding zone makes a sound due to friction dislocation, and hot or cold air emerges from the cracks; At the foot of the slope at the front edge of the landslide, there is the phenomenon of reviving the spring water that has been blocked for many years, or there are abnormal phenomena such as the sudden drying up of water (wells) and the sudden change of water level in wells (boreholes): there are cracks on the landslide body, houses are tilted, and there are phenomena such as drunken manlin and saber tree. Animals are frightened, such as pigs, dogs, cows, sheep are frightened, do not sleep, rats are scurrying, etc.
The leading edge of the collapse constantly occurs the phenomenon of falling blocks, falling, small collapses, and small collapses; New lines of rupture appear in the collapsed foot; From time to time, the sound of the cracking and rubbing of the rocks is heard occasionally; Heat, gas, groundwater abnormalities, etc.
3. What emergency measures should be taken if there are potential hazards of collapse and landslide?
Timely removal of personnel and important materials from the danger zone; Excavate drainage ditches above landslides and collapse bodies to prevent rainwater erosion; Have an evacuation route and plan in place.
4. What should I do when some suspicious abnormal phenomena of landslides and collapses are discovered?
Some suspicious landslides and collapses have been discovered, and some abnormal phenomena of landslides and collapses must be paid close attention to, and emergency measures should be taken immediately according to the occurrence of these phenomena; Immediately report to the local village committee and township government. At the same time, inform the surrounding people to be careful not to approach the landslide or collapse area.
5. How to escape in the face of geological disasters such as landslides, collapses, and debris flows?
In the face of the sudden occurrence of landslides, landslides and debris flows, it is necessary to stay calm, first judge the scope of the threat of collapses, landslides and debris flows, and then escape from the danger area in time. Specifically, when a collapse, landslide, or debris flow occurs, rolling rocks, slopes, or debris flows move from high to low, so you should choose to escape from the danger zone in both directions, rather than following the direction of rolling rocks, slopes, or debris flows. If you are on a moving landslide and you really don't have time to escape from the landslide, you can hold on to the thick trees nearby to protect yourself.
