Fire accidents of high-rise buildings in modern cities occur frequently. In the sudden high-rise fire accident, the rescue height of the fire ladder truck is limited. If you want to escape, you often have to save yourself.

If you work on the 20th floor of a 27-story building and there is a fire in this building, then you ...

Run up or down?

The fire process of a high-rise building is like a stick burning vertically, and the upward speed of the flame is much faster than the downward speed. When a tall building is on fire, no matter where the fire is, you should run downstairs quickly along the fire escape.

Statistics show that most of the casualties caused by fires are caused by inhaling smoke, so we must race against time to escape. Wet towel is the simplest and most effective tool to avoid smoke damage in fire. The wet cotton towel folded to the eighth floor can filter out about 80% of the deadly smoke.

Adopt "duck step" to keep a certain speed.

If the smoke has spread, you should lower your position and move quickly. You can use the "duck step" method, squat down, move forward with two feet alternately, and walk like a duck-this is the most commonly used way for firefighters to advance in fire fighting and rescue, so as to avoid the high temperature smoke layer overhead and maintain a certain speed.

The elevator is unavailable at this time!

In the event of a fire, the hot smoke will rush up the well at a speed of 3-5 meters per second, and the elevator will be swallowed up by the smoke instantly. In case of fire in a tall building, never take the elevator to escape!

If you escape from the balcony, connect sheets, curtains, etc. Make a rope and fall under the burning floor to escape. At the same time, it is necessary to distinguish the wind direction, and the headwind direction is safer.

When you go down to the 10 floor, you find that the 9th floor is on fire. ...

First of all, don't fantasize that you can break through the fire point, because the temperature in the fire center is above 1000 degrees, and you can't go back. Don't stay on adjacent floors, the temperature is also around several hundred degrees.

If there is no wet towel, stick to it for 3 minutes at most. If you have this towel, you can stick to it for 15 minutes at most. You should turn around and go to the floor above 12 or 13 to find a suitable room.

Don't choose a room with a security net to escape.

You'd better find a room closest to the main road when you escape, so that you will be the first person rescued by firefighters. This room must have windows and no safety net.

In all fires, because firefighters are extremely busy, in order to effectively rescue the most people in a short time, the people at the security window are always the last to be rescued.

After you and your colleagues enter this room, the first action is to close the door, the second action is to seal all the air conditioning outlets you can see with your most commonly used tape, and the third action is to smash the windows of your room. Of course, if there are many people, these actions can be performed at the same time.

What if I stay in my room?

First of all, don't shout for help, because it will consume more oxygen and inhale too much poison gas.

Second, if it is in the daytime, look for brightly colored clothes or cloth strips and shake them out of the window to attract attention; If it is at night, you should use a flashlight to attract attention, but in a fire, if there is no flashlight, a lighter is definitely not a good choice, because in a fire, the lighter will not obviously lead to the explosion of combustible gas;

Third, any towel soaked in fire is a welcome thing. Covering your eyes and nose will keep you going for a long time, thus giving firefighters more time to save you.

Whether the evacuation stairs are unobstructed becomes a "life-saving straw"

However, it should be noted that there is no formula for fire escape. Whether waiting for rescue in the house or evacuating from the evacuation stairs, various means are used to deal with different situations.

Now looking at the burning building in London, it is difficult to escape and rescue. Whether the evacuation stairs are unobstructed has become the last "life-saving straw" to escape.

According to experts, from the information currently available, the fire floor is about 80 meters, and the arm distance of the conventional lift car is about 50 meters. If there is a suitable rescue platform, it will increase the possibility of survival.

Understand 4 kinds of life-saving equipment

If you want to escape from a high-rise fire, you can't do it without excellent adaptability. At the same time, you should also know some fire escape tools.

Escape descent device

、

The escape descent control device consists of a speed limiter, a safety belt, a safety hook, a steel wire rope and other parts, and can carry a single person weighing about 100 kg to freely descend at a descent speed of about 1.5m/ s. This kind of equipment can be bought online and kept at home in case of emergency.

rescue air cushion

This is a kind of high-altitude lifesaving equipment which uses inflation to produce cushioning effect. The height of the building is only 3 ~ 4 floors, and its application scope is limited.

Roof lowering device

This device is installed on the roof of a building, and its components include a ball, a bracket and a sliding platform. A steel cable with a hook is hung on the ball, and the roof descending device is often a "life-saving straw" for the survivors.

Flexible lifesaving slideway

This is a life-saving device commonly used by firefighters. When a fire broke out in a high-rise building, firefighters rushed to the scene to combine the lifting device with the guide rail. At this time, the guide rail, the lifting device and the evacuation passage window of each floor can form a temporary emergency passage to communicate with the ground.

High-rise fire, focusing on prevention. High-rise buildings should have complete fire-fighting facilities, so don't panic at the beginning of the fire. Put out the fire at the first time, and ask the people around you to put out the fire together. You can't ignore a small fire and start a big fire.
