According to network statistics, in the past three days, the search volume for many survival supplies has risen ten times or even twenty times than usual. Among them, lifesaving flashlights, safety hammers and the like are particularly noticeable. So how can we be self-seeking under heavy rain? Is lifesaving hammer the most practical?

Cars flood escape online crazy spread, a variety of escape techniques are endless

The door is the best escape route

The Guangqumen car was flooded and the man inside the car died. The netizen said that the car was a good car and the electric window shaker caused by the flooded circuit failed to win the window. If it is manual, then there will be no drowning?

Auto industry insiders: This is not correct. The Guangqumen flooded car is a modern Tucson, 200,000 less than a more general car. The door involves an electric window shaker and a central control lock. Low-end vehicles ranging from 3 to 50,000 yuan now have this type of configuration. The car is not easy to escape because it is misread.

In addition, the manual window is not affected by flooding, and it can be shaken to escape the window. Electric windows are affected by the depth of flooding and may malfunction. In addition to the control locks on the doors of most vehicles, each car door has an independent insurance deduction. This is a mechanical device that is not affected by flooding. The occupants in various positions on the car can independently open this lock, so the choice of door escape is The best channel. The car in Guangqumen had a fatal problem. The central control lock did not open, so it was necessary to open the central control door lock for the first time.

Escape hammer is not everything

After the floods in Beijing, there was a hot surge of “escape hammers” on the Internet. Since Beijing's torrential rains on the 21st, there are 1080 people in Beijing who have purchased security hammers online. The number of transactions has reached 1,225, ranking the first in the country. The data shows that in the last two days, 14 people in Yangzhou purchased a safety hammer online and ranked 48th among the 100 cities with statistics. So, how can the escape hammer be used after the car is flooded?

Insiders in the automotive industry: The online hot escape hammer is not a panacea, unless it is best not to use it as a last resort. Because it is very difficult to break the toughened glass in the narrow compartment, it will also delay valuable escape time.

If an escape hammer is used, the water level in the vehicle is already higher than the windows of the vehicle. The difference in water pressure inside and outside the vehicle becomes smaller. At this time, the escape hammer hits the corner of the side window of the vehicle and it is easy to break the glass. After smashing the glass, remember to use a escape hammer to scrape around the broken glass so as not to be injured by the sharp corner of the glass when you escape.

Remember, hitting the car's front glass is not the best option, because the front stop is a double-jacketed glass that is very difficult to crush.

After launching the vehicle, it can be reactivated or can be reimbursed

Yesterday a microblogging reminder is very high in the amount of forwarding, which mentioned that after the vehicle wading in the armpit, do not start it twice. Otherwise, the insurance company will not pay claims.

Experts explained that at present, various insurance companies have different types of insurance coverage for wading claims. According to different insurance policies, there are differences in claims.

Guan Meng, deputy general manager of the insurance division of the People's Insurance Company of Beijing Branch, said that there is no additional insurance coverage for the philanthropic insurance, but there is an additional insurance called "engine special damage insurance," which is required to be insured with the vehicle damage insurance at a price of approx. It is 5% for vehicle damage insurance. As long as the insurance involves the wading damage of the engine, even if it is ignited and extinguished twice or more after the ignition, PICC will be paid.

Yang Yongxin, manager of insurance department of Dongfeng Nissan Huashengchang 4S shop: For insurance companies that provide wading insurance as an additional insurance, no compensation is provided for vehicles with re-ignition. Because the insurance company believes that the damage caused by the vehicle's secondary ignition is not caused by wading, it will not be settled.

However, there is a kind of additional risky “vehicle parking insurance”, which can compensate the damage caused by the vehicle’s wading, and the benefit of this insurance is that the insurance company will reimburse the transportation expenses within ten days of repairing the vehicle.

Experimental operation:

Car flood escape skills: the most practical use of the most effective

On July 21 and 22, Beijing received the largest rainfall in 61 years, a large number of cars were flooded, and some people were trapped in drowned cars. Faced with the "gateway", how can a car race help itself? The reporter collected some practical underwater escape methods. It has been experimentally confirmed that the most practical door exit, hammer hammer window most useful.

With respect to underwater escape, there are various opinions on the Internet. Some people say that when the water level is balanced, the doors are pushed open, including from the front passenger cabin. Others say that using various tools to open the windows or escape from the front windshield, Which method is the most practical, the shortest escape time, and the strongest operability? Some media have done a special underwater escape experiment for cars.

Before the experiment, the staff did some preparatory work, a tested car, purchased escape hammers, knives, flashers, hammers, ladies' high heels, and scissors.

After everything was ready, the person who got on the train to carry out the escape operation said that for the first time, the car was pumped into the water in three experiments. When the water pressure was balanced, the driver’s door was pushed open to test whether he could use the left side door to escape; When the car enters the water, try using a tool to break the window to escape and check which tool is the most effective. After the third car enters the water, use tools to break the front windshield. Which method is the most effective test?

For the first time: the car just got into the water and pushed slowly to open the door

Usually, after the car is launched on the Internet, the door cannot be opened because of the low water pressure inside and the large water pressure outside. However, in the experiment, the car door could be opened after the car entered the water, because the water pressure is very small when the water just begins to submerge into the wheel. Water needs to be injected into the car for half an hour. When water enters the car, the water pressure starts to increase. Water gradually submerges into the lower edge of the car window. The water pressure in the car reaches its maximum value. At this time, you need to exhaust all your body. Force can open the door.

In addition, when the car sinks into the water, the speed is relatively slow, which creates enough time for the escape, which is totally different from the idea that the car fell into the water when it was imagined. At this time, people in the car have a long time to escape. They should calm down, unfasten their seat belts, and forcefully open the doors. The entire escape took 1 minute 29 seconds in the experiment.

The second time: The escape hammer can break the window with a hammer

The second time the car got into the water, it used scissors, high heels, escape hammers and other tools to try to open the window. However, in fact, these tools are not broken in the water. In fact, only a handful of more than 20 money hammers are needed. Break through the glass.

In addition, some people may ask: "There is no hammer in the car, how to break through the glass to save themselves?" In fact, the car has been prepared for hard objects in the window. When it is trapped in the car, it is only necessary to unplug the headrest from the seat and use the back of the headrest. Two sharp steel plugs slam into the corners of the side windows. At this time, the glass will be smashed and can escape smoothly from the window.

Third time: The front windshield can hardly break in water

When the vehicle is not in the water, you will find that no matter how much force you put on your feet or use your ankles, the front windshield will never be broken, because the front windshield is made of laminated glass and is almost impossible to use in water. break in

Therefore, rumours that it is possible to crash the front windshield are completely misunderstood, that is, the use of watches, belt buckles, escape hammers, high-heeled shoes and other hard objects will not work.
