Doctors say the escape time is only 30 seconds after the car is flooded.

After the end of the experiment, according to the real experience of the reporters and divers in the car, combined with the expert's statement -

Car flooded "Escape Book" published according to the reporter's real experience in the production of divers

After the real-life experiments were completed, the newspaper summarized the “Escape Book” for you based on the real experience of the car reporter and fire diver, combined with the opinions of many experts.

After the car goes out, the escape time is only 30 seconds

“The normal time for water-sucking citizens to get around in the water is about 1 minute, and people who don’t know water-based are only able to close for 30 seconds.” Li Jiahong, a doctor at Nanchang Emergency Center, told reporters that this means that if the vehicle is extinguished, After the car is filled with water, most citizens have only about 30 seconds of escape time. "Therefore, the probability of a successful escape is very small when the vehicle is extinguished."

“The 120 gold rescue time is only 4 to 6 minutes. When we arrive, it is very likely that we are powerless.” Li Jiahong suggested that “When the public encounters a similar danger, they must force themselves to calm down. Let’s take a look at the car door. No, if you can, escape immediately; if you can't, call the police and break it yourself to fight for survival.”

Insider Reporter

The rear seat window is converted into a hand-type

In real-life experiments, when the water flooded the experimental vehicle 3/4, even if the oxygen cylinder protection was known, the reporter inside the vehicle was familiar with water, but the sultry environment inside the vehicle and the water level of the chin did not change the psychological situation of the reporter. For ordinary people, when faced with a disaster, it is certainly difficult to maintain psychological calm, but this is the key to survival.

When the reporter inside the experimental vehicle entered the water 3/4, he had shaken the window with his hand and the window was shaken off - the intensity was almost the same as that of the hand-cranked windows on the shore. According to this experimental result, a car reporter suggested that female owners could consider changing the windows in the back seat of the car into a hand-cranked type, which would not only be laborious but also provide opportunities for survival.

If the window is still in the central control mode, the female owner should immediately move to the back seat in the event of flooding. Because the weight of the car's engine tilts the body, an "air chamber" is formed in the rear, where more oxygen is available. At the same time, because the car begins to dive from the front, the rear window glass must enter the water later than the front window glass. This means that the rear window glass will receive less water pressure than the front window glass, and even the water level will not reach the window glass temporarily, and female owners can fight for more time to beat the glass.

Fire Diver

Point hammer is an effective tool

After the end of the experiment, the fire diver Cao Dongjun stated that the hammer is an effective tool from a variety of experimental methods and his own experience - provided the hammer's head is sharp enough. "People do not exert force on the bottom of the water. If the surface area of ​​the hammer is too large, the power will not be concentrated and it will be difficult to open the window. Therefore, the public must choose a metal hammer because it has a small weight. The head is sharp and the power can be concentrated.” He also reminded that the length of the metal mallet can be chosen to be about 50 cm, which is convenient for use in the narrow space inside the vehicle.

The greater the water level difference, the harder the door opens

Professor Fu Fangzheng of the Department of Physics of Nanchang University told the reporter that when a car is flooded into the water, it may be due to a short circuit in the car, causing the car door to lock up. At this time, the window should be broken out and the sooner the better. If the door is not locked, because of the good sealing of the car, in general, there is a gap between the internal and external water levels. The greater the water level difference is, the harder the door is to open.

He gave us a calculation in a vehicle without water. Assuming that the door is 1 meter wide and the water outside the vehicle is 0.3 meters (no water in the car), the pressure outside the door is about 45 kg. We pushed the door on the side of the door, taking into account the long arm, only slightly more than half the force of 45 kg can be used to push the door open. If the water outside the car is flooded through the door 1 meter (no water in the car), the water pressure is 500 kg, and the door can be opened with a force slightly greater than 250 kg.

Therefore, when the flooded door is less than 0.4 meters, it is better to open the door (only less than 40 kilograms of force). When the door cannot be opened, explosive power can also be used, or a stick can be used to make the seal be destroyed, so that the water can come in part, so that the water level difference is small, the pressure is small, and the door is easy to open.

If the car has been water how to count it? Fu Fangzheng said that if the vehicle is 0.5 meters away and 0.2 meters into the vehicle, then using their height difference is 0.3 meters, still nesting in the previous formula, the answer is to open the flooded vehicle door 0.4 meters below.

Side window glass is easier to break than front and rear windshield

Some netizens believe that it is more convenient to open the skylight to climb out than to break the glass. Is this true? Shen Demin, manager of Jiangxi Guangdian Baodi Auto Sales Service Co., Ltd., said that it is not always true. If the sunroof can be opened, it means that there is electricity in the car. Then most of the side window glass can be lowered. Citizens can drive windows or skylights to escape.

Which car glass is easier to break when you escape? Shen Demin said that the front windshield of the car is much stronger than the rear windshield and side window glass. The front windshield of the vehicle is strong in automotive glass and is generally double-jacketed and difficult to open. Therefore, breaking the front windshield in a short time, it is almost impossible to have a large enough area for people to go out through the hole. The side window glass has a smaller thickness than the front and rear windshields and is easier to break.

Shen Demin reminded that in general, after a car falls into the water, it will float in the water for about 2 minutes. Therefore, the citizens have to use their only time to escape from the window and escape.

Insurance company

Car owners can choose to waive damage insurance

The reporter learned from the Jiangxi branch of China Ping An Property Insurance Co., Ltd. that as of now, this year, the company received 486 cases of compensation for vehicle water, and the compensation amounted to nearly 2 million yuan. Most of these compensation vehicles belong to the computer board. damage. The staff member stated that flooding and wading driving caused by heavy rain and other disasters are insured, but engine damage caused by wading is a vehicle damage insurance. General electronic components are damaged, and the insurance company is responsible for cleaning and repairing. Etc. In order to better protect the vehicle and avoid the risk of engine damage caused by wading and flooding, the owner may choose to insure against wreckage.

The staff member stated that if the water level in the driving area reaches 2/3 of the front bumper or tyres, it should be stopped immediately, and the manpower or other vehicles should be organized to assist in dragging out; if the vehicle turns off in stagnant water, do not restart the car. If the engine is damaged due to minor fires, the vehicle should be towed as soon as possible to a safe place with little accumulated water, and call public security, 4S shops, or insurance companies to call for assistance. It is worth noting that if the vehicle enters the water, it must travel at a slower speed, and it should not stop in the water. After the vehicle runs out of the flooded road, it cannot drive at high speed immediately. After confirming that the brake is effective, it can run normally.

The newspaper microblogging live quote netizens hot discussion

On the 26th, this newspaper broadcasted live Weibo on the whole process of the experiment, which attracted the attention of many netizens. The netizen “Zhongwangwangzj” said: “To pay tribute to the courageous and devoted journalists!” The netizen "mio's sky" expressed his concern for the experimental reporters while admiring. "Reporters should do more such meaningful things." But pay attention to safety."

More netizens expressed their expectations for the experimental results. The netizen “Book Wants Glass” released Weibo, anxiously inquiring about the experimental results and the correct escape method: “How to come out after the window break? Can the door open? Or climb the window?” and the netizen “IPRist Wang Yu” Put forward expectations: “Summarize experience and inform the public.” Netizens hope that reporters participating in the experiment can sum up the experience of escape from flooded vehicles and provide references for more people, so that the issue of “how to escape in falling vehicles” can be further improved. For the authoritative answer.

At the same time, this newspaper also thanks all the cooperation units for their great support (in no particular order): Nanchang Water Public Security Fire Brigade, Jiangxi Lilin Horticultural Engineering Co., Ltd.
