What will happen to us when heavy rain comes?

Recently, all parts of the country have entered the flood season. The disasters in Jiangsu, Anhui, Hubei, Hunan and other places are still continuing. Our neighbors Xinxiang Urban District, Huixian City, Hebi City Qibin District, Qixian County, etc. Extremely heavy rains fell across the ground. Starting at 3 a.m. on July 9, a super heavy rain of more than 250 millimeters occurred in Xinxiang for 3 hours. According to convention, 250 millimeters in 24 hours is already the highest level of heavy rain. The rainfall in Xinxiang in 6 hours was 345.3 mm, the highest among prefecture-level cities in the country this year, far surpassing Wuhan!

So what should we do in the face of heavy rain?

Heavy rain warning signals are divided into four levels, represented by blue, yellow, orange and red respectively.

Heavy rain blue warning signal: The rainfall will reach more than 50 mm within 12 hours, or has reached more than 50 mm, which may or has already caused impact and the rainfall may continue.

Heavy rain yellow warning signal: The rainfall will reach more than 50 mm within 6 hours, or has reached more than 50 mm, which may or has already caused impact and the rainfall may continue.

Heavy rain orange warning signal: The rainfall will reach more than 50 mm within 3 hours, or has reached more than 50 mm, which may or has already caused a major impact and the rainfall may continue.

Heavy rain red warning signal: The rainfall will reach more than 100 mm within 3 hours, or has reached more than 100 mm, which may or has caused serious impact and the rainfall may continue.

When traveling on rainy days, you need to pay attention to:

Pedestrian safety

1. Avoid dangerous areas such as floor-to-ceiling billboards, transformers, and telephone poles

There are more thunderstorms in summer. Pedestrians should pay more attention when traveling in this weather and try to avoid areas such as street light poles, signal light poles, air conditioner outdoor units, and floor-to-ceiling billboards. Do not get close to or take shelter under overhead wires and transformers, because strong winds may break overhead wires, and lightning strikes and heavy rain can easily cause short circuits and discharges of bare wires or transformers, posing a threat to personal safety.

If you find a broken wire falling into the water, do not handle it yourself. You should immediately mark the surrounding area and call the police immediately. Once a wire happens to break on the ground very close to you, don't panic, let alone run away. At this time, you should jump on one leg and leave the scene, otherwise you may get an electric shock when crossing the wire. If someone is electrocuted and falls to the ground, do not panic. Stay calm and separate the person from the source of electricity with a dry stick. Remember not to use your hands to pull the person who is being shocked without safety measures, otherwise you may get an electric shock.

2. Choose a sturdy, high-lying building to take shelter from the rain

If you happen to be outdoors before a rainstorm, try to find a safe place to stay until the rainstorm ends. This safe place must be a solid building or a building on higher ground. If a rainstorm is about to begin, while taking shelter from the rain, try to contact your family and tell them your specific location to reassure them. When choosing a shelter from the rain, stay away from temporary fences at construction sites and fences built on hillsides.

3. Do not wading rashly, be wary of puddles and manhole covers

Due to continuous heavy rainfall, water is prone to accumulate on the road, and sediment, garbage and other objects are washed into the water. , passers-by walking there must be careful at this time. We can see the large suspended objects above the stagnant water, but we don't know what's underneath the stagnant water. So don’t wade into the water hastily. Otherwise, once you fall into a manhole, pit or hole, it may cause greater unsafe factors.

4. Pay attention to lightning protection and do not take shelter under trees or make phone calls

When heavy rains are accompanied by thunder and lightning, pedestrians should also pay attention to lightning protection. Try to stay in a safe building and stay dry. If there is no building to hide from and you are caught in the rain on the road, never stand under a tree or telephone pole, and throw away the umbrella in your hand, because the metal on the umbrella frame may also conduct electricity. In addition, mobile phones must not be used if you are outdoors during thunder and lightning weather.

5. The elderly, children, and pregnant women should try not to go out alone on rainy days.

In case of windy and rainy weather, try to avoid going out alone. In particular, the elderly, children, and pregnant women should try not to go out alone. If you must go out, you should wear raincoats, ponchos and other rainproof tools. Pay attention to safety on the road and keep a wide distance from vehicles and pedestrians in front of you.

If you are outdoors, wear rubber shoes to avoid electric shock. When it rains heavily, don’t ride hard just to avoid getting caught in the rain. Instead, focus on seeing the road conditions ahead clearly. The roads will be muddy and slippery after rain, so you should slow down your riding speed.

Driving Safety

Rainy days are the weather with a high incidence of traffic accidents, because the clarity of the driver's vision decreases in the rain, the friction between the tires and the ground decreases, and the road conditions are waterlogged and complex, which can easily lead to accidents. It is easy to cause traffic accidents, so driving safety in rainy days requires more vigilance.

1. Slow down and keep a safe distance between vehicles.

When a heavy rain comes, don’t drive fast because you are anxious to get home. Choose a place where you can safely take shelter from the rain.

If it starts to rain heavily, when driving on the road, you should reduce the speed and turn on the front and rear fog lights of the car to prevent the car behind you from rear-ending due to poor visibility.

Slow down when meeting or overtaking cars on the highway, because the rain splashed when meeting cars will temporarily form a line of rain and fog to block all your sight, and you will lose your sense of direction in a few seconds. and difficulty seeing anything outside the vehicle.

2. When encountering waterlogged roads, do not drive blindly.

Like pedestrians walking on the road, you can’t see what’s going on under standing water. When you have to pass as a last resort, observe the traffic conditions of the vehicle in front. If the water is more than half a wheel, do not force it. At the same time, it is best to drive strictly according to the ruts of the vehicle in front to avoid hitting the opened manhole cover. It is also necessary to maintain an emergency handling distance of at least 10 seconds from the vehicle in front. In extreme cases, space is time, and time is life.

When encountering large blisters, you should first observe carefully. Places with waves and whirlpools are likely to have open manholes or some obstacles at the bottom of the water. Places with calm water surfaces are generally The water may be deep.

When passing through standing water, get out of the car and test the depth of the water, or see where the water reaches the vehicle when the vehicle in front passes. If the water depth exceeds half the height of the wheels or submerges the exhaust pipe, do not drive into the water again.

When driving in water, use a low gear and try not to stop or change gears. When driving in stagnant water, drive at a low speed and gently apply the brakes a few times to drain the water that has seeped into the braking system.

3. Turn off the flame in the water and do not start it immediately.

Setting out in water is the most feared situation for drivers on rainy days. Once you encounter this situation, do not restart the engine immediately. To prevent water from entering the engine and causing the vehicle to be scrapped. At the same time, pay close attention to the water level. When the water floods into the car and continues to rise, you must leave the vehicle and walk to higher ground.

Once the car stalls in the water, do not try to ignite it again, but immediately turn off all circuits in the car, push the car to the side of the road, and wait until the water level recedes to the exhaust pipe before starting it again. When driving, you should first apply the accelerator to "dry" for a while.

In addition, there are two places that you cannot go to when driving in heavy rain: one is the underground parking lot. The second is on the bottom floor of an overpass or in a sunken tunnel. Because water flows downward.

4. Keep the wiper performance in good condition and maintain good vision.

Keep your wipers performing well. Clean the rainwater on the windshield in time, and adjust the wiper gear appropriately according to the amount of rain to maintain good visibility. When driving, it suddenly starts raining outside, the temperature drops, and the temperature of the windshield also drops. The water vapor in the car condenses into mist when it encounters the windshield, blocking the view. In this case, you need to Turn on the air conditioner and blow it in the direction of the windshield.

When the visibility is extremely low during heavy rain, the headlights, side lights and rear position lights should be turned on. When the vehicle behind and the vehicle in front of you are traveling in the same direction at a close distance, you must not use high beams, and Pull the vehicle off the road or park it in a safe place.

5. Keep a sufficient distance from bicycles and pedestrians on rainy days.

The vision, hearing and reactions of cyclists and pedestrians wearing raincoats on rainy days are not very sensitive. On the one hand, they must slow down to prevent water from splashing on pedestrians, and on the other hand, they must avoid danger. Due to poor visibility caused by pedestrians and cyclists wearing rain gear on rainy days, and the panic caused by pedestrians and cyclists rushing on their way after rain, it is very easy to cause traffic accidents due to poor observation.

When driving on a rainy day, when you encounter pedestrians holding umbrellas or wearing raincoats walking on the road, you should honk the horn in advance to warn them, reduce the speed appropriately, pay attention to their movements, keep a certain distance from each other, and pass at any time. Be prepared for unexpected situations. When driving a car through a road with stagnant water, special attention should be paid to slowing down, not to rush around pedestrians, and to keep a certain safe distance from them to prevent muddy water from splashing on pedestrians on both sides of the road.

Pedestrians or cyclists wear rain hats, which restricts their sight and hearing; cyclists hold the handlebars in one hand and hold an umbrella in the other and sway from side to side, making it difficult to see clearly the traffic situation and vehicles. When approaching, prevent them from suddenly turning or slipping.

How do we respond to heavy rain disasters?

How to deal with heavy rain disasters?

Quickly move to the nearest hillside, high ground, building, flood shelter, etc., or immediately climb to a rooftop, high-rise building, tall tree or other high place to take temporary refuge.

"Small-scale" measures can be taken for protection, such as building fences, installing water barriers at gates, and configuring small water pumps.

Once outdoor water floods into the house, the power supply should be cut off immediately to prevent electric shock and injury.

Do not transfer alone.

If the flood continues to rise, make full use of the prepared life-saving equipment to escape or quickly find some floating materials such as door panels to build a raft to escape.

Do not climb live telephone poles or iron towers, nor climb to the roof of a mud house.

When you find that the high-voltage power line tower is tilted or the wires are broken and sagging, you must stay away to prevent electric shock.
