Apr 24, 2018

Recently, a fire broke out at the Trump Tower in the United States, killing one occupant and injuring six firefighters. This fire was another high-rise building fire accident that took place after the fire on the apartment building in London, England, on June 14 last year. It also once again sounded the alarm for fire safety.


In recent years, high-rise buildings have been built higher and higher and more densely built, and the fire safety problems that accompany them have also become increasingly prominent. On February 9, 2009, the building under construction of the affiliated cultural center of the new site of CCTV caused a fire due to the illegal discharge of fireworks, causing serious damage to the facade of the cultural center. On November 15th, 2010, a 28-story house in the Jing'an District, Shanghai, which was undergoing the construction of the external façade wall, ignited the surrounding flammable materials and caused a huge fire, resulting in 58 people were killed and more than 70 were injured. The property lost nearly 500 million yuan.

The main reason for high fires in high-rise buildings

From the perspective of the building itself, some high-rise buildings of earlier construction ages were not fire-fighting facilities due to the low level of fire protection established by relevant state-of-the-art technical standards at that time. There were also difficulties in the later stage of renovation, and there were also some construction materials. There is no requirement for fire performance. For example, no specific regulations are provided for the external thermal insulation materials of buildings. Once a flammable building insulation layer is exposed to fire, the fire spreads rapidly and three-dimensional combustion can easily occur. CCTV West Building Fire, London apartment fire are all reasons for this.

From the point of view of the management and maintenance of firefighting facilities, the damage and lack of fire protection facilities in some high-rise buildings are prominent. There are several reasons for this. First of all, some high-rise buildings do not have the management of property service companies at all, and some property service companies do not incorporate the management and maintenance of fire-fighting facilities into the scope of service management, resulting in the long-term disrepair of key facilities such as the water system and alarm system in the building. Play a role. Secondly, some high-level communities do not pay a high rate of property fees, which also results in insufficient funds for the property units and insufficient management personnel. In addition, some high-level owners are reluctant to use large-scale maintenance funds, resulting in difficulties in the maintenance and repair of fire facilities at a later stage.

The phenomenon of internal disorderly dumping is prominent. The fire load of a building is certain at the beginning of the building design. In particular, evacuation routes are to strictly manage and regulate combustibles. However, in reality, residents in some high-rise buildings will have bicycles, Old furniture and other debris were piled up at random, some occupied stairwells and some occupied evacuation walkways. On the one hand, it has seriously hindered the evacuation of escape routes. On the other hand, these debris are mostly combustible and flammable substances, which are more likely to cause the spread of fire. Some high-level tenants have for a long time evacuated the fire doors of stairwells in an open state for the convenience of them, so that fire doors will not be fireproof and smoke-proof in fire situations. If a fire occurs on any floor, the smoke and fire will quickly spread and spread, posing a serious threat to the evacuation of people.

Fire trucks occupy a serious phenomenon. Due to the relatively high concentration of people, logistics, and traffic in high-rise buildings, the construction of parking facilities and other supporting facilities is far from meeting the actual needs of parking. Once poor management results in chaotic parking of vehicles, especially at night and holidays, the problem of occupying and blocking fire truck lanes Especially outstanding.

How to escape a fire in a high-rise building

Because the evacuation staircases in high-rise buildings have closed stairwells or smoke-proof stairwells, if there is a fire in the walkway or in other households, after knowing, first observe the smoke in the corridor. If there is no smoke, escape can be quickly evacuated along the stairwell. If there is already smoke, you can use a damp cloth to block the door, stand on the balcony to open the window, alarm, wait for the rescue.

In addition, the city’s firefighting department reminded high-rise tenants and high-rise residential buildings to keep the fire doors of evacuation staircases intact and in a state of normal closure. Homes should be equipped with simple fire fighting facilities such as escape masks. In the fire escape, wear an escape mask and maintain a stooped posture. If you do not have a mask for escape, you can use your wet towel to cover your mouth and nose to escape. It should also be noted that the size of the towel should be moderate, and it can protect the mouth and nose area. At the same time, it must stack three times to reach eight layers, so that it can filter toxic fumes.
