.

Special note: the external wall insulation project has lasted for about 30 years, especially from 2000 to 2014, a considerable number of external wall insulation materials of buildings are combustible and non combustible materials

.

If this notification is true, that is to say, the residents and properties have defects in the initial fire fighting and alarm, which has delayed some time; Secondly, the building was opened in 2008 and put into use in 2009

.

Resident fire 5

.

Some netizens sighed: this kind of insulation layer is covered with gusset plate, there is a gap between gusset plate and insulation layer, and the fire spread rapidly along the gap, even if there is spraying, it can’t hit the fire point; The fire spread in the lower part of the corridor

.

At about 16 p.m

.

After the property arrived, the room was full of smoke

.

It was very hard and dangerous

.

Now we have a preliminary understanding of the cause of the fire

.

Why is it so difficult to put out the fire? After the 19th floor household fire, 127 fire engines and 558 firefighters from five fire brigades were dispatched, and helicopters and 101 meter high fire engines, the highest in China, were dispatched

.

When the temperature reaches, a wall will be involved in the combustion instantly; Second, there are no fire-fighting facilities on the outer wall

.

Earlier official news: at 16:02 on August 27, 2021, Dalian fire rescue detachment received an alarm that the exterior wall materials of block B of Triumph International in the development zone were on fire

.

The fire fighting lasted more than 7 hours, which was very difficult to put out the fire

.

Even if it is not a super high-rise building, the 31 floors are at least more than 90 meters high, which should be classified as a class of high-rise public building

.

There is a risk of spread of the whole building in case of fire, which needs more attention

.

Why did the fire burn so big

.

Whether the automatic sprinkler system is started or not has not been officially announced, so further investigation is needed

.

The detachment command center immediately dispatched 24 fire stations, 68 fire engines and 366 commanders and fighters to the scene for rescue

.

For a fire, the speed of plane combustion is relatively slow, but the vertical combustion is not fast

.

When fireworks spread to this part, it is easy to store heat and expand the fireļ¼ˆ 2

.

Pay tribute to them

.

According to official news, the fire was basically extinguished at 23:00 p.m

.

First of all, according to the official news, that afternoon, a household on the 19th floor caught fire

.

Triumph International Building is an apartment building with 419 households and 818 people living in

.

With a total construction area of 63000 square meters, Triumph International is composed of two air connected super high-rise buildings and podium buildings, facing the 360 degree open view of the sea, mountain, port and city of Dalian Bay

.

that day, a fire broke out in a market in Dalian, and the subway was temporarily closed

.

The power supply and gas of the building have been cut off, and the cause of the fire is under investigation

.

What is the reason for this? First, it burns very fast

.

The owner went to the property for help

on the 27th, with no casualties

after the fire, the property owner confirmed the fire and gave an alarm after asking for help and arriving

After it is set up, there is nothing to put out the fire; Third, the fire brigade is facing the adverse situation of large-scale fire fighting and control

Unit (individual) fire emergency (self rescue and fire extinguishing) 8

.

After the fire, no trapped persons were found and no casualties were found through community telephone contact and fire fighting layer by layer

.

Sometimes it takes a few minutes

.

Liaoning Provincial Fire Rescue Corps mobilized 4 high-rise rescue and fire-fighting formations, 59 fire engines and 192 commanders and fighters from Anshan, Yingkou, Liaoyang and Panjin fire rescue detachment to rush to the scene for reinforcement

.

The planning and design of the project is completed by a world-famous design company, and the shape is inspired by the “Arc de Triomphe” of lade fangs, CBD District, France

.

Are fire fighting facilities functioning? According to the code for fire protection design of buildings, this building has 31 floors

.

Does this mean that the automatic fire alarm system did not act or that although it acted, the attendant in the fire control room did not effectively deal with it? According to the later fire video, the flame enters the building B and burns

.

Many fire fighting forces in Dalian have invested in fire fighting and rescue

.

When the high-pressure jet fire truck is spraying water, the parking and operation area is small, the location is unfavorable, and the water supply intensity is difficult to control the fire in a short time

.

For the external control high-pressure jet truck, there are many jet blind areas, which is impossible to really stop the fire; The corridor between the two towers is directly baked by the fire at the lower part, which is not only easy to burst into the room, but also the building components of the outer wall will deform rapidly, forming a large number of falling objects, which directly threaten the surrounding personnel and vehicles

.

Since the building fire-fighting facilities are installed inside, there are no fire-fighting facilities on the outer wall

.

Triumph International’s building type is high-rise tower, and the property type is ordinary residence, apartment and commercial residence

.

Fire facility operator 9 The backer of the unit’s fire protection work (Management) is shantun gossip, which is not in love with the past, not miscellaneous at present, not welcome in the future, and indulge in moving forward

.

On the one hand, it is necessary to organize fire control in the direction of the outer wall, on the other hand, it is necessary to control from the inside to avoid the inward spread of the fire, and on the other hand, it is necessary to search, rescue and evacuate the personnel inside the building, which puts forward high requirements for the dispatch of fire forces, on-site organization, coordination and command

.

Fire investigation report and case 6

.

According to the specifications, automatic fire alarm system, automatic sprinkler system, fire hydrant system, etc

.

In this fire, the firefighters went deep into the fire floor and braved the fire and smoke on the top floor to control the spread of the fire

.

It is a scarce resource in Dalian

.

that day, a household on the 19th floor caught fire

.

After the property arrived, the room was full of smoke, and then called the police

.

The building covers an area of 63000 square meters

.

At that time, the external wall insulation materials of the building may not be incombustible materials, which also led to the spread of fire along the external wall (for details, please refer to this article: Why did the fire of Zhongxin building burn so much); Third, the building has a corridor at the top

.

The falling of combustibles on the outer wall is easy to cause personal injury and damage to combat vehicles and equipment

.

Another reason to mention is that at about 13:00 p.m

. Fixing Socket Cross Hole Nail Plate

Backer’s words: 1

.

Statistics show that Triumph International is located at the intersection of Jinma road and Heshan West Road, Guobin Road, Jinpu New District, Dalian, close to Jinma road light rail station and only a short distance from the welcome square

.

The fire formed three-dimensional combustion

.

Therefore, it’s too difficult and too pit (using a 101 meter high car to put out the fire)

.

When the fire has not been completely extinguished, the landmark building is on fire again, and the fire fighting is facing the situation of two-line operation

.

If it is a super high-rise apartment building, it is a class of high-rise public building

.

Street store fire 3

.

In addition, there is a risk of setting up a position under the building
