How do high rise fires occur? How can we avoid high rise fires?

There are many reasons for fires in high-rise buildings, and in order to avoid fires, it is necessary to increase relevant fire protection knowledge. <>

The difficulty of fire fighting in high-rise buildings is mainly caused by a variety of factors, and it is very difficult to extinguish a fire in a house with a height of more than 15 floors. First of all, because most of the fire trucks can only reach the 15 20 floors. In the event of a further fire, then the fire engine is basically useless.

That's where the ladder comes in. Although ladders can reach a height of more than 20 floors, they have higher requirements for the foundation environment of the ground. Wider roads are generally required as a prerequisite for rescue activities, but some of the older settlements do not have such foundations.

For example, in August 2021, a fire broke out in a landmark building in Liaoning Province. Because the fire was at the top, and the weather conditions that day contributed to the spread of the fire, the local fire department had to send a large number of firefighters. According to reports, 24 fire stations were dispatched in Dalian City, Liaoning Province, and a total of 68 fire trucks arrived at the scene, which lasted more than 6 hours before being extinguished.

Before 2009, polyurethane foam was widely used as a thermal insulation material for China's top management. The material is extremely flammable, and in the event of an open flame, the fire can easily burn along the wall and get out of control. According to statistics, 30% of high-rise fires are caused by electrical causes.

Nowadays, there are more and more electrical equipment, and many electrical equipment can easily lead to short circuits and fires due to unqualified quality or improper use. And in recent years, the phenomenon of short circuits caused by electric vehicle charging has become more and more frequent. Therefore, it is recommended that you never put electric vehicles into your home to charge, because the safety hazards are too great.

Now some kitchens will use all kinds of open flames, some combustible gases will burst into flames, children playing with fire, smoking carelessly will cause ** disaster. Open flames may occur when some workers are repairing buildings, such as electrocuting, gas cutting, and welding. Improper operation or violation of operating procedures may result in a fire.

High-rise fires may occur when cooking gas or electricity is used for cooking. High-rise homes should be equipped with fire-fighting equipment. Always ensure that the fire escape is clear. Fire hydrants have water.

High-rise fires generally spread upwards from the lower floors, or a large area of ** occurred on the upper floors, as well as short circuits in the lines. Residents living in high-rise buildings should take measures to prevent fire and electricity, improve their awareness of fire prevention, and do not store some flammable and easy-to-use items at home.

If there is a fire in a high-rise building, it is usually caused by our irregular electricity consumption, and in other cases, it is caused by the gas not being turned off, so the fire will occur.

When a fire breaks out on a high-rise building, the last thing we should do is take the elevator and jump off the building. When a fire breaks out, everyone needs to stay calm, do not panic, can hide in a relatively safe place and wait for rescue, and find a way to call for help, or quickly choose the right route to escape. When escaping, you need to wear an escape mask correctly, or cover your mouth and nose with a wet towel, and try to keep your posture as low as possible to prevent inhalation of toxic gases in your body.

Summer is a hot time for fires, and fire safety cannot be ignored, especially in high-rise buildings in cities.

More and more, population density.

It also increases, so it is even more necessary to improve people's awareness of fire safety.

The meaning of taboo is: no!

Don't panic.

In the event of a fire, you must remain calm and do not panic, get up and run blindly or jump off the building. It is necessary to understand the location of the environment you are in, grasp the size and spread direction of the fire in time, and then choose an escape method and escape route according to the situation.

Two taboos shouting blindly.

Due to the indoor use of a large number of wood, plastic, chemical fiber and other flammable and combustible materials in modern buildings, and the surface of decoration materials is often painted with paint, a large amount of smoke and toxic gases will be emitted when burning, which is easy to cause suffocation and death of toxic gas. Therefore, when escaping, you can fold it with a wet towel, cover your nose and mouth, hold your breath, and play a role in filtering smoke. And it is necessary to adopt a crawling way to escape.

3. Don't be greedy for money.

Don't waste time trying to get dressed or find valuables when escaping, don't be under pressure to take your belongings and don't get caught up in the fire.

Fourth, avoid opening doors and windows indiscriminately.

When evacuating, never open doors or windows. If the evacuation room is full of smoke and it is impossible to evacuate, open the door or window on the side of the fire and reclose it immediately after the smoke has been discharged. Otherwise, a lot of smoke will pour into the room, visibility will be reduced, and the heat will be flooded, and it will be impossible to hide.

Five taboos to take the elevator.

Don't just go to the elevator. Because once it catches fire, the elevator will lose power, and there is a high chance that people will be trapped in the elevator and unable to escape.

Six taboos run at will. Do not run at will on the fire ground, otherwise it will not only be easy to burn yourself, but also cause new burning points and cause the fire to spread. If the body is on fire, you should take off your clothes or roll on the spot in time to extinguish the fire, you can also pour water on your body, and wrap the fire on your body with wet quilts, wet clothes, etc.

Seven taboos are in the wrong direction.

Evacuate from high to low places, and escape from high floors to low floors, because the fire burns upwards and the flames will burn from the bottom to the top. The fire on the renovated floor usually spreads faster than the speed of a person's escape, and when you can't run to the roof, the fire has already developed in front of you, so the flames will always surround you. If you have to do so, you can flee to the top of the building, and stand upwind of the roof.

Arise and quench the fire.

Eight taboos easily jump off the building.

If the fire breaks through the evacuation room, do not make the decision to jump off the building if there is no way to evacuate, at this time, you can grab the balcony or windowsill and climb out of the window to survive.

Remember: be calm!

Why didn't I pass the review, did I make a mistake? You shouldn't run down in smoke or jump off a high-rise building.

Well, I don't know, right==

But my first instinct was not to jump down.

When a high-rise building is on fire, you should run down to avoid the fire scene. If a fire occurs, you must cover your mouth and nose with a wet cloth, and then run away, if you can't escape, you must not rush to jump off the building, you must be calm.

If you live on the top floor, it's best to run up. When a fire occurs, be sure to cover your mouth and nose with a wet towel, stay away from flammable materials, be sure to take the safe passage, do not take the elevator, and pay attention to sending out a distress signal.

You should run down, and if there is a safe exit, it is best to escape through the safe exit, so that you can better ensure safety.

A kind of fire escape device for the metal rod segmented buffer of the building is to install a metal rod outside the wall of the building, the bottom and top of the rod are fixed on the ground and the wall of the building, and the outer circle of the metal rod has a plurality of semicircular grooves from top to bottom.

When a fire breaks out in the building, the trapped people can put their own landing disc on the metal pole from the platform or window of the building, and stand on the landing disk, hold the metal pole in their hands, and press the brake pedal with their feet, and the landing disc will descend to the ground at a safe speed.

This device is to rely on the self-weight of the human body to descend the segmented buffer, there is no harm to the human body, because there is no electrical device, and the mechanical structure is simple, therefore, this device can not only be used on the building of any height, and the cost is low, no maintenance is required, the use time is long, safe and reliable, and can make the trapped personnel of the building continuously safe escape at the speed of about 10 seconds. 15902741861 Patent Application No.:

The correct way to escape in the event of a fire on a high-rise floor.

When a fire breaks out in a high-rise building, the correct escape methods are: try to use the facilities in the building to escape, and use the fire elevator to evacuate, but when the fire is fired, the ordinary elevator must not be taken; Use indoor smoke-proof stairs and ordinary stairs to close stairs for escape; Escape by using the balcony, corridor, evacuation floor, etc. of the building.

When a fire occurs, the trapped people should have a good psychological quality, do not panic, stay calm, choose the right escape method, the temperature at the fire scene is very amazing, and the smoke will block the view, so in this case, you need to stay calm and not panic.

Due to its special structure, once a fire breaks out in a high-rise building, it is more dangerous than an ordinary building, and if it is not properly disposed of, life is often in danger. So, when you are in this situation, it is important to stay calm and not panic.

First of all, you must quickly identify which direction is up and down, left and right in your room**, and then decide on an escape route to avoid straying into the "fire mouth".

If you find that the doors, windows, passages, and stairs have been blocked by fireworks, but there is still a possibility of rushing out, you can pour some water on your head and body, or cover your head with a wet towel or sheet, and wrap your body with a wet blanket or quilt to rush out of the danger zone.

If the smoke is too thick for people to walk upright, they can crawl against the ground or wall roots and pass through the danger zone. When the staircase has been burned down and the adjacent passage is blocked, the other room can be accessed through the balcony or window, from where it can be quickly evacuated to the indoor fire elevator or outdoor fire staircase.

If the door has been sealed by fire, do not open it easily to avoid fire, pour more water on the door to prolong the spread time, and wait for a piece of clothing to stick out of the window or shout loudly to attract the attention of rescuers.

If there are rainwater pipes, running water pipes or lightning rods outside the windows of the building, you can use these to climb down; You can also use a strong rope, (if you can't find it for a while) you can tear the cover, bed sheets, curtains into strips, twist them into ropes) and tie one end to the window frame or bed frame, and then slowly go down. If you are too high from the ground, you can go down to a non-hazardous floor, kick the glass of the window you pass by with your foot, and then go down from there.

If you live close to the roof, you can go straight to the roof platform or balcony and wait patiently for the arrival of rescuers, but in either case, don't jump down, because then there will be only death and no life.

1. Calm first. First of all, you must calm down, and if the fire is not big, you can take measures to extinguish it as soon as possible. If the fire is fierce, call the police at the first time and evacuate quickly.

2. Pay attention to the wind direction. The evacuation direction should be determined according to the wind direction at the time of the fire, and before the fire spreads, quickly leave the disaster area in the direction of the headwind. Generally speaking, when the floor where the fire broke out is above your own floor, you should quickly run downstairs.

When escaping, pay attention to closing the doors and windows on the passage to prevent and delay the flow of smoke to the escape passage.

3. Cover your nose with a towel. Fire smoke has the characteristics of high temperature and high toxicity, and it is easy to cause respiratory scalding or poisoning after inhalation. Therefore, cover your mouth and nose with a wet towel when fleeing, and try to avoid shouting loudly to prevent smoke from entering your mouth.

You can also find water to wet your clothes, cloth, etc. to cover your mouth and nose. When passing through the smoke zone, move as quickly as possible in the lowest position or in a prostrate position. Be careful to breathe small and shallow.

4. Knotted rope escape. When the passage of the building is blocked by fire, and there is no way to escape, you can tear the sheets, quilt covers or curtains into ropes, tie the window sill firmly, and slide down the rope. If you have a rope at home, you can directly tie one end of it to a door, window cabinet or heavy object and climb down along the other end.

In this process, it is necessary to pay attention to the use of both hands and feet (the feet are twisted into a clamping rope, and the hands are climbed up and down alternately), and the handle should be protected to prevent the hands from being taken off or worn out when sliding down.

5. Temporary evacuation. When there is no way out, you should actively seek temporary shelter. In large-scale multi-purpose buildings, evacuation rooms located at the ends of elevators, corridors, and toilets can be used to avoid the hazards of fireworks.

If you are temporarily trapped in the room, close all doors and windows leading to the fire area, block the cracks of the doors and windows with soaked bedding and clothing, and splash water to cool down to prevent external flames and smoke from entering. When trapped, take the initiative to contact the outside world so that you can be rescued as soon as possible.

6. Hide against the wall. When firefighters enter a burning house, they grope along the walls, so when they are suffocated by smoke and lose their ability to save themselves, they should try to roll towards the wall or doorway. At the same time, doing so will also prevent the house from collapsing and injuring yourself.

Everyone is praying for peace. But there are unforeseen circumstances in the sky, and people have good and bad luck. Once the fire came, surrounded by thick smoke and flames, many people died in the flames, and some survived.

There are only desperate people, there is no desperate situation, "in the face of billowing smoke and raging flames, as long as you are calm and witty and use the knowledge of self-rescue and escape from the fire, you have a great possibility to save yourself."

** Point on this or upper floor, and quickly escape down through the safety exit. ** Point on the lower level, fire and smoke have blocked the downward passage, choose another route or go home and wait for rescue, depending on the situation.

When escaping from the fire, wear an escape mask or cover your mouth and nose with a wet towel to prevent inhaling toxic smoke. If you are waiting for help at home, try to choose a room with an exterior window. When entering the room, seal the gap between the door with a wet towel, clothing or bed sheet, and cool the door with water.

If you are waiting for help at home, you can call for help by making noises or lights at the window and waving your clothes.

Do not use the elevator to escape after a fire. Do not blindly jump off the building to escape, and choose a reasonable escape method according to the size of the fire and the height of the floor.
