How to avoid danger in heavy rain?

In case of rainstorm, residents should immediately close the doors and windows, avoid places with metal pipes, cut off the power supply of household appliances, and do not stay on the balcony of high-rise buildings.

Low-lying courtyards, bungalows or basements are flooded. At this time, the power supply should be cut off to prevent electric shock, and then the general personnel should be transferred to a safe area. Finally, all effective measures should be taken to keep the water out of the door and eliminate indoor stagnant water.

If you encounter thunderstorms and strong winds in the street, pedestrians should immediately enter the room to shelter from the rain, and never stay under tall buildings or large billboards to avoid falling objects and hurting people; If you are walking by the lake or river at this time, you should squat down in a low-lying place, put your arms around your knees, put your legs together, keep your chest close to your knees and keep your head as low as possible. Don't touch the ground with your hands, avoid the thunderstorm under the big tree, get close to the water, use mobile phones, etc.

1. What disasters should we pay attention to after the rainstorm?

1, get an electric shock in waterproof

In a storm, if you find that the high-voltage tower collapses, the wires sag or break, stay away from it and don't touch or approach it. If a broken wire gets stuck in the stagnant water on the ground, you can cross the stagnant water with one foot. If someone gets an electric shock in the water, the power department should be required to cut off the power supply in advance when the rescue is launched. If the rain stops during the rescue, the electric shock victim can be separated from the stagnant water with insulators.

2. Stay away from the factory.

At present, many factories are steel frame structures, which are easy to collapse in a storm. In addition, the interior, roof, wall roots and surrounding areas of some adobe houses cannot withstand flooding. Before the danger comes, citizens should evacuate dangerous buildings in time, find a safe area with a higher position as soon as possible and wait for rescue.

Step 3 avoid lightning strikes

Generally, heavy rain is accompanied by lightning. At this time, don't stay on the platform of high-rise buildings, nor should you enter the isolation shacks and sentry boxes in outdoor open places. It is not advisable to prevent thunder showers under big trees. As a last resort, you must keep a distance of 3 meters from your torso, squat down and put your legs together. Take shelter from the rain in the city and stay away from bare metal objects such as water pipes and gas pipes and electrical equipment.

4, flood siege waiting for rescue

In case of flood siege, you should quickly move to the commanding heights such as roofs and tall buildings and wait for rescue. If the communication tools can't be used normally at that time, let rescuers know where you are by means of fireworks, lighting, burning clothes, etc., and don't blindly wade to escape.

Second, what should I do if I encounter heavy rain and flash floods in special scenes?

1. What should I do when driving in a rainstorm?

Many people like go on road trip now, but go on road trip is most afraid of some bad weather problems. What should we do if there is a rainstorm? Experts tell us that when driving in a rainstorm, the visibility is reduced, the ground is slippery, and sometimes there are bad weather such as thunder and lightning, so you should:

1), turn on the lights, hold the steering wheel tightly, drive carefully, pay attention to pedestrians, drive at a low speed and use the brakes carefully. Because the tire adhesion coefficient is low, the braking distance will be longer, which is very prone to accidents.

2) In case of rainstorm, don't risk driving. You should choose a higher safety zone for parking.

3), not familiar with the road conditions, do not know the water depth, do not easily let the car wade.

4), don't accelerate, so splashing rain is easy to be inhaled by the intake pipe, causing damage. You should slow down as much as possible, turn down the throttle and proceed cautiously.

5) When it thunders, close the doors and windows and stay in the car.

6) Never start the car again after accidentally turning off the engine with water, otherwise the engine will be "reimbursed". On the contrary, you should contact the insurance company as soon as possible and notify the 4S shop for rescue. You can also ask passers-by to help you push the car out of the water and fix it as soon as possible.

7) If you need to drive in an emergency and have to drive in a rainstorm, you should take necessary protective measures: first remove the air filter or raise the air inlet hose, or connect the exhaust pipe with a rubber hose. Keep the air inlet and exhaust port of the car as far away from the water surface as possible to reduce the possibility of water entering the engine.

8) When driving, try to avoid the water waves held by the other car when driving, and stop to let the other car pass first if necessary.

9) When the submerged height reaches the wheel radius, try to avoid wading vehicles. Use low gear, use less oil and drive slowly and at a constant speed.

2. What should I do if I encounter a thunderstorm while traveling?

In case it rains, put on rain gear immediately. Don't wear it because it's light. It's too late to wear it when it's soaked! Be sure to put the rain gear in a convenient place, such as the side pocket, the top pocket or the top of the main pocket of the backpack.

No matter how boastful the backpack manufacturer is about the waterproof property of the product, it is necessary to put a waterproof cover on the outside of the backpack. Clothes and sleeping bags in backpacks should be wrapped in waterproof bags or plastic bags, and fragile and moisture-proof food, medicinal materials, negatives or matches can be boxed with hard shells for preservation. The map must be protected from getting wet by rain, and put in a convenient place, such as a raincoat pocket or a backpack top pocket.

Thunderstorm weather is unlikely to be struck by lightning, but it is better to be careful when encountering emergencies and lightning. In a thunderstorm, the following points are crucial:

1), don't avoid thunderstorms under boulders, cliffs and caves. When the current passes through these places, it will produce an arc, which will hurt people who take shelter from the rain. If the cave is deep, you can try to hide in it.

2) Don't ride a bike or a horse in a thunderstorm, let alone fly a kite. Flying a kite in the rain will lead to lightning strikes.

3) Don't hide in isolated huts in the wilderness. Buildings are good places for lightning protection.

4), leave the highlands, don't shelter under the tree.

5) The car is an ideal place to avoid lightning. Even if lightning hits the car, it rarely hurts people.

6) If you are swimming or in a boat, you should go ashore immediately. Even on a big ship, hide under the deck and don't touch any metal objects.

3. How to prevent mountain torrents?

In a short period of time, when there is continuous rainstorm in an area, the river will rise violently, overflow dams, flood farmland and villages, and destroy roads.

Bridges and houses, this is a flood disaster. How should we save ourselves when the flood comes?

1), threatened by flood, if there is enough time, it should be moved to hillside, highland and other places in an organized way according to the predetermined route; In the case of being caught off guard and surrounded by floods, we should use boats, rafts, door panels, wooden beds, etc. Let the water transfer as much as possible.

2) When the flood comes too fast to be transferred, you should immediately climb the roof, tall buildings, big trees and high walls, take refuge temporarily and wait for rescue. Don't swim alone.

3) In mountainous areas, flash floods are prone to occur if there is continuous heavy rain. In this case, we should pay attention to avoid crossing the river and being washed away by mountain torrents, and also pay attention to preventing landslides, rolling stones and mudslides.

4) It is found that the high-voltage wire tower is toppled, the wires are drooping or broken; Stay away from danger, don't touch or get close to it to prevent electric shock.

5) After the flood, take medicine for epidemic prevention, do a good job in health and epidemic prevention, and avoid infectious diseases.
