The probability of a high-rise building fire is as high as 41.55%! The National Firefighting Electric Power Conference will be held!

A high-rise fire in London warned China. July 7 afternoon, hold a national high-rise building fire safety comprehensive management of mobilization will be a teleconference. Shanghai TV reporter learned from the Shanghai branch that in order to learn the lessons from the high-rise fires in London, Shanghai, as a city with 1/10 of the number of high-rise buildings in the country , will strictly control the key fire safety aspects of high-rise buildings, including external wall insulation. Materials, fire evacuation routes and other links are included. Shanghai Municipal Party Committee Standing Committee, Secretary of the Municipal Law Commission Chen Hao, Deputy Mayor Shi Guanghui, and Gong Tao, Director of the Municipal Public Security Bureau attended the meeting.

First, data analysis

According to statistics, Shanghai has 27 meters above the high-rise building 31 000 (of which more than 100 meters of high-rise buildings near 600), the number, scale ranks first in the world. From the perspective of fire accidents in high-rise buildings , between 2007 and 2016 , a total of 4,293 fires occurred in the high-rise buildings in Shanghai , causing 474 deaths, 106 injuries and direct property losses of 289 million yuan. In particular, accidents such as "Shanghai World Financial Center Construction Site Fire", "Oriental Pearl Fire", and "Jingan Jiaozhou Road Teachers' Apartment Apartment" are very serious. The impact is huge and the lessons are profound.

Can understand the above data, high-rise building with 10-year life of the calculation, the probability of occurrence of fire was 13.85%, 30-year life calculation, the probability of occurrence of fire as high as 41.55%. If calculated according to the design life of a high-rise building for 70 years, the probability of fire is almost 100% . This is far from the understanding of everyone's mind. Many construction units and use units claim that their own building management is in place and there will be no fire. In front of the data, such subjective rhetoric appears pale and powerless. In the event of a fire, a huge loss of life and property will not be said. The relevant responsible persons will face legal penalties, and it is a lifelong responsibility system. In other words, even if you leave the building that was once in charge, as long as the investigation of the fire accident determines that you are clearly responsible for negligence during your employment, you are still liable.

Second, there are difficulties

1. There are "hard injuries" in the fire safety of some buildings. Some high-rise buildings that were built earlier were difficult to implement fire reconstruction according to the current regulations. Before the implementation of the “High-rise Civil Building Design Fire Prevention Code”, Shanghai had built more than 1,200 high-rise buildings. In addition, according to statistics, Shanghai's high-rise buildings aged over 15 years account for 46% of the total .

2. There are "soft ribs" in daily fire safety management. At present, nearly 74% of high-rise buildings in Shanghai have not set up industry committees, and some high-rise buildings have unclear property use, and are divided into small property rights for sale or sub-tenancy, and “residential reform”, office renovation, and office renovation are more common. .

3 , fire fighting difficulties. High-rise buildings have high floors, complex functions, and many vertical pipelines. After a fire, they can easily produce a “chimney effect”, spread rapidly, and are evacuated slowly. It is difficult to extinguish fires and has always been an international fire problem.

Third, the solution

Shi Guanghui, deputy mayor of Shanghai, gave important instructions. In order to learn the lessons from the high-rise fires in London, the city of Shenzhou must strictly control the key fire safety aspects of high-rise buildings:

1 , strict control of external wall insulation materials. For existing high-rise buildings that use flammable combustible external insulation materials, they should be replaced in conjunction with reconstruction and expansion projects. Before the demolition, strict management measures should be followed to set up warning signs.

2 , strict management of building fire protection facilities. The lack of facilities shall be combined with reconstruction and expansion projects to be added; if facilities are damaged, rectification and restoration shall be carried out within a time limit; for those with insufficient number of evacuation stairs, measures shall be taken to increase outdoor evacuation stairs; and tube wells and cable bridges for cable wells, pipeline wells, etc. If the blockage is missing or not tight, seal it tightly.

3 , strict management of fire evacuation channels. Completely clean up the evacuation stairs, stack debris and illegally parked and recharged electric vehicles, etc.; ensure that the fire doors of the evacuation stairways function as fire and smoke, and ensure that the emergency lighting and evacuation signs in the evacuation walkways and staircases are complete and easy to use. .

4 , strictly investigate fire violations. To make full use of legal methods, the construction units, construction units, supervision units, and product production and sales companies that falsify and reduce standards in the supply, testing, construction, and other links shall be top-ranked according to law. High-rise buildings that are difficult to rectify, difficult to fire, and have major hidden dangers must be listed and supervised.

5. Strictly implement anti-personnel and physical protection measures. It is necessary to vigorously promote the use of Internet of Things technology (mobile Internet technology), use fire-fighting remote monitoring systems, and real-time monitor the status data of water pressure, water level, and alarm information of the fire protection system, and incorporate it into the management of “smart cities”. It is necessary to encourage the deployment of technical prevention facilities such as simple showers, stand-alone (wireless) fire detection alarms, and efforts to enhance the protection level.

Fourth, policy support

1. Legislation

Shanghai plans to launch a revised version of the “Shanghai Fire Protection Regulations” in 2017 , which will increase the requirements for social organizations to deploy smart fire protection systems.

2 , project

The Shanghai Municipal Science and Technology Commission and the Shanghai Municipal Commission of Economics and Information Technology have established innovative projects and financial support for relevant technology companies.

3 , pilot

Encourage social organizations to actively deploy firefighting Internet of Things and fire information products.

With the nationwide high-rise building fire protection and comprehensive management mobilization deployment video and telephone conference held, we can easily find that regardless of the 6.14 London fire or the 6.22 fire in Hangzhou, the painful lessons have been turned into the government's determination to manage strictly! All firefighters and property practitioners should take an active action and use a rigorous, responsible, innovative and responsible spirit to seriously respond to the government's call to implement the spirit of the meeting and provide the people with a safer living environment.
