How do you save yourself when your car falls into water

Every year, a large number of cars go into the water. As a result, 30 percent of people drown. Many people drown when they cannot open their car doors. To make it easier for you to understand, let's do an experiment.

First, we got a car with two people in it, real people, of course. Get someone to push the car into the water. Look, the car falls into the water. The engine is heavy, so it goes down nose and tail. Soon, drilling, water from all gaps of the car to the feet, to the waist, to the eye, good, now have to escape, so the driver try very hard to push the door, use the power of the body, the door is steady wire, the driver tried various methods, all run out of strength, the doors still can't open it, soon, the water over the top of the head, the pilot was dead. Of course, just as he was about to hang up, an oxygen mouth came over, this is a test, of course not to hang up people. Take over the oxygen mouth, the driver sit quietly in the car, after a while, the car filled with water, the driver a push door ---- opened, the door was actually very easily opened.

What is the reason? Why in the water did not fill the car, the door will not open ------ this is because there is air in the car, inside and outside the pressure difference caused by the water exerted on the door of the force to reach 150 kilograms, you certainly can not open. By the time the water filled the car, the pressure difference between inside and outside was balanced, and we could open the door as easily as if we were in the air. How could the man drown when he was finally filled with water? Simply put, it's because you exhaust yourself trying to open the door before it fills up. You can't hold yourself up for more than a few seconds once the water is over your head, so you die quickly, which is what it takes to fill up the car.

OK, so what should we do when disaster strikes?

Now, let's try it again: a car, two people, and then the car is pushed into the water. According to the deployment in advance, the driver do not do anything, save physical strength and deep breathing, quietly wait for the water to fill the compartment, a second, two seconds, the water quickly flooded up. One minute and 37 seconds later, water filled the car, the car was balanced from head to foot, at this time, the driver pushed the door - the door opened, so the driver easily surfaced. This is the right way to escape, don't waste your physical strength and oxygen before the pressure on the door disappeared, but in real life, we don't know how deep the water is, don't know if you can hold on to that time, don't know if you will stay calm, so this is not a surefire way.

Okay, do we have any other options? Yes, that is when the water comes over the door of the car, and you open the door, although there is pressure, the pressure is not at its maximum, if you have enough force., of course, this is a critical point, that is when the water over half of the door is your chances of a second from bottom, or otherwise your strength is not in the water "over the door after filling in front of the car" opens the door again, of course, you need to be able to hold out until the water filling of carriages and keep good physical strength and oxygen will be the last chance.

It seems that opportunity always favors those who are prepared. Well, that's not very safe yet. Is there any other way?

Yes, there is another saying ------ just roll down the window and get out of it. Okay, so let's try that out, and the car gets pushed in again, unfortunately, it gets pushed off again. Soon, the water filled the car, at this time, whether we are hand or electric, the Windows are not moving, the same way, the pressure on the window is 150 kilograms, you still can not open. But what this experiment also showed is that you can still use electrical equipment when you're underwater, and it doesn't fail immediately. If we fall into not very deep water, we can try to shake the glass down before the water overflows the front of the car.

Seem, above this method also not good, how to do, dead end? No, someone said, if we find something to break the window, the water will fill the car quickly, and we can get out through the window or open the door and get out. Okay, let's try it again. Oh, the unfortunate car, was pushed in again, and soon the car was filled with water, and the driver took what was available at the time, a set of keys, what you would find in the car at the moment, and he hit the glass, and the glass didn't respond ---- No. Instead, he pushed against the glass with the heel of his shoe. The glass did not respond. At this time, the next person to take out a small car escape device, toward the window glass a pressure ---- glass immediately and broken, water quickly poured in, ten seconds later, the car filled with water, the door opened. Oh, hooray, this is the real way to save your life. Put a small car escape device on your glove compartment or key ring. It can save your life in an emergency.

As a result of rainstorm water a woman driver trapped dead, in fact trapped in the car to escape, you only need to pull down the seat headrest, with the two sharp plug on the side of the glass, glass frame is the most-easy to break, this is originally designed to take into account.
