Cut off the dangerous outdoor power supply in the low -lying land.

Do not walk in the flowing water, and the 15 cm depth flow can make people fall.

When the water flows in the mountains, the water flows are turbulent, turbid, and mixed with mud, it may be a precursor to the outbreak of the mountain floods, and the stream or river channel should be left.

During the heavy rain, driving should turn on the rain and fog lights, slow down, pay attention to preventing mountain floods, and avoid stagnant water and landslides.

Pay attention to the power facilities on the street. If there is a wire slip, stay away and report the power department immediately.

Meteorological disaster chapter

Lightning defense

Lightning is a cloud discharge with lightning and thunder.

Defense measures:

● Should stay indoors and close the doors and windows; personnel who work outdoors should hide into the building.

● Do not contact the antenna, water pipes, wire mesh, metal doors and windows, buildings of the building, and stay away from electric wires or other similar metal devices.

● Avoid using telephone and wireless telephone.

● Do not swim or engage in other water sports. It is not advisable to perform outdoor balls, climbing, riding and other campaigns, leave the water surface and other open spaces, and find a place with lightning protection facilities to avoid. ● Do not stand on the top of the mountain, the roof or other protruding objects, and do not close the objects with high conductivity.

● When you cannot hide in a building with lightning protection facilities in the wilderness, you should stay away from pointed objects such as trees, electric poles, masts.

● It is not advisable to drive or ride a vehicle.

Strong wind defense

▲ Try to reduce going out. When you go out, you must ride a bicycle less. Do not stay and avoid the wind under the billboard and temporarily.

▲ If you are driving, you should enter the underground parking lot or hidden place.

▲ Carefully close the window in the room, and put a rice -shaped tape on the window glass to prevent the glass from crushing and stay away from the window to prevent strong wind from sweeping sand and stones to break the glass to hurt people.

▲ In public places, evacuation should be evacuated to designated locations.

▲ Agricultural production facilities should be reinforced in time, and mature crops should be harvested as soon as possible.

Geological disaster chapter

1. What is landslide and collapse?

Lirtening refers to the natural geological phenomenon that the rock body or soil on the slope is under the influence of natural environment conditions and human engineering activities along a certain weak surface or weakly with the overall or part of the slopes. Mountain.

Collapse refers to the geological phenomenon that suddenly breaks away from the mother's collapse, rolling, and accumulating on the slope (or grooved valley) under the action of gravity.

2. What are the signs of landslide and collapse?

The front edge of the landslide has a horizontal and longitudinal radiation cracks, and the phenomenon of bulging in the front edge of the front edge; the fissure of the back edge of the landslide is lengthened and widening, the new cracks are constantly generated, the back of the sliding body is quickly under the seat, the surrounding rock and soil body is relaxed, and the small collapse of the small collapse is collapsed. Phenomenon; sliding rock and soil elapse due to friction, and hot air or air -conditioning from the cracks; at the foot of the front edge of the front of the landslide, there is a phenomenon of resurrection of spring water that has been blocked for many years, or the water (water well) suddenly drys. (Drilling) Water level mutation and other abnormal phenomena: There are cracks, house tilt on the landslide, and drunk Hanlin, horse knife tree and other phenomena. Animals are frightened, such as pigs, dogs, cows, sheep are frightened, not sleeping, mice are scratching.

The phenomenon of falling, falling, small collapse, and small collapse of the forefront of collapse; new rupture traces of the collapse feet appear; from time to time, the sound of tear friction of rocks occasionally; heat, gas, and groundwater abnormalities appear.

3. What emergency measures should be taken to collapse and landslides?

Move personnel and important supplies away from the dangerous area in time; excavate drainage ditches above the landslide and cliff collapse to prevent rainwater from being washed; formulate the evacuation route and plan in advance.

Fourth, when some suspicious abnormal phenomena of landslides and collapse have been found, what should I do?

Some suspicious declines of landslides and collapse, the abnormal phenomenon of collapse must be paid attention to, and immediately take emergency measures based on the occurrence of these phenomena; immediately report to the village committee and township government. At the same time, inform the people around you not be careful not to approach the landslide and collapse the area.

5. How to escape when facing geological disasters such as landslides, collapse, mudslides, etc.?

In the face of dirt, the sudden occurrence of landslides and mudslides should be kept calm. First, judge the scope of the threat of collapse, landslides, and mudslides, and then escape the dangerous area in time. Specifically, when collapse, landslides, and mudslides occur, rolling stones, slopes, or mudslides are moving from high places to low places. Escape from the direction of the slope or mudslides. If you are on the landslide that is being moved, there is no time to escape the sliding body, and you can hold the large trees nearby to protect themselves.
