What should be prepared in advance under natural disasters such as heavy rain?

Rainstorm is a natural disaster that happened recently. Although it is autumn, it doesn't affect its arrival at all. When the rainstorm comes, you should first close the doors and windows to prevent rainwater from rushing into the house and cut off the dangerous outdoor power supply in low-lying places. Secondly, try not to take underground passages and elevated passages when going out. Don't walk in running water, running water 15 minutes can make people fall. Moreover, when driving in heavy rain, please turn on the rain fog lights (double jumping lights are easy to affect the vehicles behind, and turning left and right is easy to mislead others). Slow down and try to avoid waterlogged roads. In addition, pay attention to the power facilities on the road. If you see wires falling off, try to avoid them.

Rainfall increases in flood season every year, and some areas are prone to strong convective weather such as local short-term thunderstorms, strong winds and hail. Local heavy precipitation is easy to cause secondary disasters such as waterlogging, flash floods, landslides and mudslides in urban and rural areas. Then try to evacuate to a safe place before the rainstorm to prevent disasters. It is necessary for residents in rainstorm-prone areas to prepare some self-help articles, so that they can win more "vitality" for us when the rainstorm strikes and they are trapped in Wang Yang and their lives are threatened.

Residents in heavy rainfall areas should listen to the latest weather forecast released every day, and strive to evacuate to safety before the rainstorm comes to prevent disasters. Prepare the first-aid kit for dealing with the rainstorm in advance, and place flashlights, water, small radios, dry food, first-aid medicines, rescue ropes, etc. Just in case. Then, when there is too much water around our house, we should quickly move to roofs, high-rise buildings and other places; If trapped by stagnant water, observe the surrounding environment and look for door panels, washbasins, wardrobes, etc. As an escape appliance, try to seek external rescue and stand on the commanding heights immediately.

What if you unfortunately fall into the water? We should use everything that can float on the water, such as boards and trees, to support ourselves and find a safe place. When there is backflow in the local shopping mall, the trapped people should obey the instructions, evacuate and retreat in an orderly manner, and move to a higher place.

When the rainstorm strikes, if the city is waterlogged from time to time, we can generally prepare some emergency items in the car, such as safety hammers, wire saws and pillows with certain buoyancy. When trapped by stagnant water, use a safety hammer to hit the four corners of the window glass instead of hitting the windshield (the windshield is twice as thick as the window glass and is not easy to smash). In addition, compressed food, mineral water, mobile phone car charger and tactical flashlight (the light can be adjusted and flashed as a survival signal, which can also replace the life-saving hammer) are also essential supplies for driving in heavy rain.
