At 4:39 on the 23rd, the command center of the Nanjing Fire Rescue Detachment in Jiangsu Province received an alarm: a fire broke out in Building 6, Mingshang Xiyuan, Yuhuatai District.

As of 24:00 on the 23rd, the fire had killed 15 people and 44 people were being treated in the hospital.

Among them, 1 person is in critical condition, 1 person is in severe condition, and 42 people have minor injuries. Most of the 42 patients with minor injuries suffered inhalation injuries caused by inhaling thick smoke at the fire scene.

After preliminary analysis, the fire was caused by a fire where electric bicycles were parked on the elevated floors of six buildings. The specific cause is under further investigation.

　　The fire that occurred in Building 6, Mingshang Xiyuan, Yuhuatai District, Nanjing is undoubtedly a tragedy and heartbreaking.

After the fire broke out, some witnesses said that they were "awakened by neighbors in their sleep, which was suspected to be caused by the charging of the battery car on the ground floor." Others said that they were awakened by the explosion and smelled a burning smell.

At present, the specific cause of the fire is still under further investigation. Whether it was caused by an electric bicycle has not yet been finalized. It still needs to wait for the relevant departments to thoroughly investigate.

　　Why do residential fires in Nanjing cause so many casualties?

　　Why did this fire cause such serious casualties? A CCTV reporter exclusively interviewed a senior engineer of the Jiangsu Provincial Fire and Rescue Corps.

　　According to reports, preliminary analysis showed that the fire was caused by a fire where electric bicycles were parked on the elevated floors of six buildings. After the fire broke out on the first floor, the elevated floors directly connected to the patios inside the buildings, forming a chimney effect that quickly spread upwards.

　　According to the press conference, most of the 42 patients with minor injuries suffered inhalation injuries caused by inhaling thick smoke at the fire scene.

According to experts, the failure of normally closed fire doors in high-rise buildings to effectively block the spread of smoke is also an important reason for the increase in casualties.

　　Electric bicycle fire spreads quickly and produces a large amount of toxic smoke

　　In the residential building where the fire broke out, a large number of electric vehicles were parked on the ground floor. Experts said that once an electric vehicle catches fire, it will quickly enter a violent combustion stage and produce a large amount of toxic smoke.

　　There are many electric bicycles parked on the elevated floor of the residential building.

　　It is understood that the building where the incident occurred has 34 floors and is divided into 2 units. The first floor of the building is an elevated floor where some electric vehicles are parked. Let’s take a look at two pictures:

　　The first picture is of the fire scene in Mingshang Xiyuan, Yuhuatai District, Nanjing, Jiangsu Province. After the fire, you can still see many electric bicycles parked on the elevated floor of the building where the incident occurred and in the green belt next to the building.

　　The second picture was taken by a reporter in Mingshang Xiyuan, Yuhuatai District, where a fire broke out. There was no fire in this building, but we also saw many electric bicycles parked in this elevated space.

　　Netizens have something to say: Can electric bicycles be parked on the elevated floor?

　　In the face of this fire, many netizens left messages online to express their condolences for the deceased, and also expressed concerns about electric bicycles being parked on elevated floors.

　　Some netizens said:

　　"The casualties are too great. Electric vehicles really have to stay away from buildings."

　　Some netizens also reported the situation downstairs in their home:

　　“The electric cars on the elevated floor downstairs in our community are overcrowded.”

　　"The parking lot in my community is also on an elevated floor."

　　"There are so many electric cars parked downstairs that there is only a small gap where you can walk."

　　News link: What is an overhead layer?

　　Elevated layer is a term used in construction. It generally refers to the building space formed by the deep foundation of a building or the elevated portion of a building on a slope that is not backfilled with earth and stone.

According to the national standard "Uniform Standards for Design of Civil Buildings", the elevated layer of a civil building refers to an open space layer that uses structural support and has no external protective walls.

Commonly used elevated floors are those set up on the ground floor of school buildings, residential buildings and other projects. Some buildings have elevated floors on one or more floors on the second floor or above to serve as spaces for public activities, parking, greening, etc.
