A few days ago, the State Council Security Committee issued a notice on the special rectification of major fire risk rectification of high -rise buildings. The city is also conducting relevant rectifications to "physical examinations" for fire safety for high -rise and high -rise buildings.

Why do high -rise buildings "physical examination" and what are the projects? The reporter contacted Xiamen Fire and asked professionals to answer.

Who is the physical examination object?

More than 6,200 buildings

"Tall" architecture

According to the current data of the fire department, there are more than 6,200 high -rise buildings in our city, of which more than 290 super high -rise buildings (over 100 meters). The special rectification of major fire risks in high -rise buildings is to conduct fire safety investigations on these "high men".

This time, many residential buildings and office buildings in our city have been included in the special rectification inspection list. Among them, there are many citizens familiar to the Shimao Strait Building, Xinglin Bay Business Operation Center, Xiamen Wealth Center, Dijingyuan, etc.

Why check?

High -rise fires are easy to produce

"Chimney effect"

"A large amount of insulation and decorative materials are laid on the outer wall of the high -rise building. Internal elevator shafts, cable wells, air ducts and other types of vertical pipelines and wells are dense, with the characteristics of chimneys." Firefighters said that if high -rise buildings are not carried out in accordance with fire technology standards, high -rise buildings are not carried out in accordance with fire technology standards. The fire is separated, and the "chimney effect" is easy to produce after the fire. That is, the air rises or decreased along the space with vertical slope, which leads to the rapid spread of the fire and form a three -dimensional combustion.

In addition, there are generally more electrical equipment and combustible materials in high -rise buildings, which are concentrated and difficult to evacuate. Once the fire occurs, it will not only damage the building itself and its surrounding buildings, but also threatened personal safety.

Interestingly, in the special rectification operation, firefighters rarely take the elevator, and more are shuttled in the corridor. They use the decoration of flammable and combustible materials for the construction of the building, whether the fire separation is in place, whether the evacuation channel is unblocked, and whether the fire protection facilities are damaged and stopped.

What problems are found?

Fire door is not closed

Channel blocking pile debris

Firefighters sorted out the preliminary inspection. At present, the city's high -rise and high -rise buildings in our city mainly exist in the following problems: one is that the normal -closed fire door is not maintained, and the other is to evacuate the passage and the safe export to accumulate debris, and the third is the damage to the fire facilities.

"Fire door is a necessary fire prevention component for high -rise and high -rise buildings. When the fire occurs, the fire door can effectively prevent the spread of fire and strive for more rescue time for firefighters." In order to enter and exit, the fire door will open.

During the "physical examination" of the building, firefighters also found a lot of mixed stairs. "They will not only become the fire aid of the fire, but also affect the escape of residents."
