*** Last year, the number of production safety accidents and deaths decreased by 70.6% and 76.1% respectively year-on-year. From January to September this year, the two indicators decreased by 37% and 34% respectively year-on-year. At present, no major accidents have occurred in the city for 43 consecutive months.
Highlight scientific and technological empowerment and improve the level of risk dynamic monitoring
Nanjing has strengthened the construction of information platform and made every effort to improve the digital risk monitoring level by relying on big data, Internet of things and other technologies. The basic platform of three-dimensional visual urban information model (CIM) has been preliminarily built, the construction of the "urban eye" comprehensive perception platform has been accelerated, the setting of 4.7 million urban QR code standard addresses has been promoted, and efforts have been made to build a high-level urban digital base. The "bright" project of urban safety has been implemented, and the first "digital project of urban underground pipe network" has been built in China , relying on the wireless broadband government network, build the command and dispatching communication infrastructure in emergency scenarios to ensure that the city is online at any time.
The city has built a comprehensive monitoring and early warning platform for urban safe operation, developed eight business subsystems such as grid risk prevention and control, intelligent prediction and early warning and digitization of emergency plans, and comprehensively improved the monitoring and early warning level in the fields of gas, water supply and drainage, bridges and tunnels, comprehensive transportation hubs, long-distance oil and gas pipelines, flood control and waterlogging prevention. At present, the system has been applied normally in 24000 units in the city, with a total of 1 billion pieces of data.
The city has continuously expanded application scenarios, developed the "multivariable early warning analysis model of urban risk", built more than 20 subsystems and models such as major hazard sources, meteorological disasters and dangerous house investigation and prevention, and actively prevented and controlled variable risks in urban operation. Establish an online and offline management and control system for hazardous waste, and implement key supervision on enterprises with major hazard sources of hazardous chemicals, metal smelting enterprises and dust explosion related enterprises.
Innovate work measures and strengthen risk investigation and early warning
Nanjing has continuously improved the governance model of "big data + grid + iron foot board" and comprehensively and thoroughly investigated risks. Move "one net" forward to build the gateway.
1680 "emergency grids" and 17000 "safety supervision grids" are superimposed on 12000 comprehensive grids in the city, with 48000 grid members, strictly implement normal patrol and fine supervision, and continue to do a good job in safety "physical examination".
The city also accelerated the construction of an urban safety risk database, We comprehensively carried out urban risk (source) survey, identified and filed, prepared and formed a "four-color map" of safety risk distribution, investigated and marked 225000 social risk sources and 42000 enterprise risk sources, and 360000 enterprises and units were included in the platform management. We formed a "chess game" of mass prevention and mass governance 。 Innovate the multi governance mechanism and effectively guide the third-party forces to participate in the investigation and resolution of urban safety risks. Actively carry out activities such as "safety production month", further improve the system of "woodpecker" and "Whistler" of urban safety risks, establish 12345 and 12350 linkage acceptance and reporting mechanism, and encourage the masses to jointly eliminate hidden dangers and ensure safety.
Guard the safety gate and prevent the source of risk
Nanjing implemented work responsibilities, strengthened top-level design, and effectively controlled risks from the source. Strictly define the "source" of responsibility, the city has formulated and implemented the list of key work of safety production of members of the Standing Committee of the municipal Party committee and the leading group of the municipal government, defined the safety risk prevention and control responsibilities of 54 party and government departments and judicial departments, included safety development in the scope of "one vote veto", increased the assessment weight, and promoted the compaction of responsibilities at all levels. Develop and apply the "safety and credit facebook" of enterprises, customize the task list for different types of enterprises, and force enterprises to perform their main responsibilities in accordance with the law.
The city strictly controls the "source" of planning, deeply implements the concept of safe development, ensures the connection and coordination of emergency system planning with national economic and social development planning and land space planning, integrates safety requirements and safeguard measures into special planning in various fields such as industry and urban construction, further strengthens the "rigidity" of planning implementation, and effectively improves the overall safety level of the city. Strictly grasp the "source" of projects, vigorously promote the capacity adjustment, transformation and upgrading of petrochemical, iron and steel and other industries, resolutely eliminate enterprises and projects that fail to meet the safety and environmental protection standards, and shut down 1650 "three high and two low" enterprises. Strictly control the project access, take meeting the safety production standards as the precondition for attracting investment, and effectively ensure the intrinsic safety from the source.
Focus on weak links and strengthen the treatment of potential risks
The city adheres to systematic thinking and accurate policy implementation, timely eliminates all kinds of potential risks in urban operation, and continuously improves urban safety and resilience. We strengthened centralized rectification efforts, promoted the organic connection between "one-year small stoves" and "three-year large stoves", deeply carried out special rectification of work safety in 32 industries, investigated and rectified more than 46000 hidden dangers, closed and banned 297 enterprises and stopped production for rectification in 618. Taking the establishment of a national circular economy standardization demonstration park as the starting point, promote the closed management and integrated recycling of Jiangbei new material science and technology park.
The city also strengthened the construction of a resilient City, renovated 360 km of water supply pipelines, 504 km of dangerous and old gas pipelines and 703 km of oil and gas long-distance pipelines, effectively unblocking the city's "meridians". We completed the standardized treatment of 1371 dangerous buildings, more than 2600 high-rise residential buildings, 2834 rural bridges and other potential risks, opened 11000 community fire passages, and made citizens feel at ease. More than 100 waterlogging prone areas and river banks have been renovated, and efforts have been made to build an integrated urban drainage and waterlogging prevention system. Improve emergency response capacity. We will improve the emergency plan system, improve the city's regional, disaster wide and industry wide emergency rescue linkage mechanism, and build a professional emergency rescue team of 12000 people. The "Jinling emergency treasure" resource information sharing system has been built, and more than 1500 emergency experts have been stationed nationwide to realize the "same frame consultation" and scientific and efficient disposal of experts at the scene of complex accidents.
Next, Nanjing will promote the construction of urban lifeline project with high standards, continuously improve the urban safety risk prevention and natural disaster monitoring and early warning capacity, and promote the re improvement of the establishment of safe development demonstration city with the new improvement of intrinsic safety level.
