Problems identified in the identification of major hazard sources under GB18218

I asked those who work on environmental impact assessment projects about this issue, and the explanation is as follows: If a substance is not listed in GB18218, it is possible to use the classification methods and criteria outlined in GB18218 to identify major hazard sources; however, this is not mandatory, though identification is generally required. No detailed rules for GB18218 have been issued yet. So, proceed with the operation for now. In my personal view, all substances that are classified as hazardous chemicals should undergo identification as major hazard sources. It is impossible to list all the substances that need to be identified in GB18218. Or hope that an attachment will be provided in the future. This is my personal understanding; I’m not sure if it’s correct. There was a discussion on this topic in the security forum before, you can take a look...

The 33rd substance listed in Table 2 of GB 18218-2000, namely “petroleum gas,” actually refers to C2-C4. Therefore, LPG stations absolutely require the identification of major hazard sources. I strongly agree with what was said on the second floor: it is necessary to follow the classification in GB18218 for identifying major hazard sources. Taking flammable substances as an example, factors to consider include a flash point of less than 28 degrees, a flash point between 28 degrees and 60 degrees, and an explosion limit of less than 10%. Therefore, propane (2.1–9.5%) and the like should also be taken into consideration. In fact, GB 18218-2000 is not thorough enough; logically, it should list all substances that need to be controlled. Since this is a mandatory national standard, it must be specific.

I agree with the friend above: the 33rd substance listed in Table 2 of GB 18218-2000, namely \"propane\", actually refers to C2-C4. Therefore, LPG stations absolutely need to conduct identification of major hazard sources. However, since 18218 is being used, it is necessary to stay within the limits set by 18218; substances not listed there do not require identification. If one feels that this standard is not comprehensive enough, Document No. 56 can be used, as it serves as a supplement to 18218

GB18218 provides a standard for identifying major hazard sources; those that meet this standard certainly qualify. If they do not meet it, there is no mandatory requirement, but in practice, operations can still be carried out in accordance with these guidelines. Although the list of substances may not be complete, it will be updated accordingly as requirements change over time.

Regarding Document No. 56, I also asked the same person, and it is said that it is related to pipeline identification, which is different from the production and storage requirements specified in GB18218. Since I haven’t read Document No. 56, it’s difficult for me to express my personal opinion. Could someone upload Document No. 56? ?

　 Document No. 56 on Safety Supervision Coordination -------------------------------------------------------------------------------- Guidelines for the Supervision and Management of Major Hazard Sources To the safety production supervision and management departments of various provinces, autonomous regions, municipalities directly under the Central Government, as well as the Xinjiang Production and Construction Corps; to the coal mine safety inspection bureaus and the coal mine safety inspection offices in Beijing and the Xinjiang Production and Construction Corps; and to relevant enterprises under central government administration: In accordance with the relevant provisions of the Work Safety Law, in order to fully understand the number, status, and distribution of major hazard sources, strengthen their supervision and management, and effectively prevent serious and catastrophic accidents, since November 2003, the **Production Supervision and Administration Bureau (**Coal Mine Safety Inspection Bureau) (hereinafter referred to as the **Bureau) has carried out pilot programs for the registration of major hazard sources in Hebei, Liaoning, Jiangsu, Zhejiang, Fujian, Chongqing, Guangxi, and Gansu. Following the issuance of the State Council’s Decision on Further Strengthening Work Related to Work Safety, various regions earnestly implemented it and successively carried out surveys, registrations, and monitoring of major hazard sources. To strengthen management, standardize practices, and ensure orderly operations, the following guidelines are hereby provided for the supervision and management of major hazard sources. 　　I. Significance and Basis Guided by the important thought of “**”, it is necessary to fully implement the Work Safety Law, adhere to the principle of “safety first, prevention first”, put people first, and adopt a scientific development concept that is comprehensive, coordinated, and sustainable in order to promote the all-round development of the economy, society, and individuals. It is also essential to shift focus to earlier stages in the process and to lower the threshold for taking action, as well as to rely on science and technology to enhance work safety. These efforts are aimed at transforming work safety practices from passive prevention to proactive management at the source, thereby preventing and reducing the occurrence of serious and major accidents. 　　Article 33 of the Work Safety Law stipulates: “Production and business operation entities shall keep records of major hazard sources, conduct regular inspections, evaluations, and monitoring of them, and formulate emergency response plans to inform employees and relevant personnel of the emergency measures to be taken in such situations.” Production and operation units shall, in accordance with **relevant regulations**, file records of their major hazard sources sowie the relevant safety and emergency measures with the departments responsible for work safety supervision and management at the local level and other relevant authorities. The “Decision of the State Council on Further Strengthening Work Related to Work Safety” (State Council Document No. 2) requires “conducting a comprehensive survey and registration of major hazard sources, as well as strengthening the monitoring of such sources at the national, provincial (regional/municipal), municipal (prefectural), and county (city) levels”. 　　II. Objectives and Tasks The supervision and management of major hazard sources is a systematic task that requires rational design and comprehensive planning. First, it is necessary to conduct a comprehensive survey and registration of major hazard sources ； Next is to carry out detection and assessment of major hazard sources ； Third is to implement monitoring and prevention for major hazard sources ； Fourth, address the defective and accident-prone hazard sources ； Fifthly, through the monitoring and management of major hazard sources, it is necessary to encourage enterprises to strengthen their internal management, implement relevant measures, and ensure their own safety. At the same time, actions should be taken in line with the actual conditions in different regions, so as to facilitate unified leadership, scientific decision-making, and the enforcement of monitoring and work safety regulations in accordance with the law, thereby achieving a more scientific, systematic, and standardized approach to the supervision and management of major hazard sources. 　　Main tasks: 1. Conduct a comprehensive survey and registration of major hazard sources to determine their overall number, understand their conditions and distribution, and establish a database for such sources along with a regular reporting system ； 　　2. Conduct safety assessments of major hazard sources, carry out regular inspections of important equipment and facilities as well as process parameters and hazardous substances in the production process, and establish a daily management system for the assessment and monitoring of major hazard sources ； 　　3. Establish a four-level monitoring and information management network system for major hazard sources at the national, provincial (regional/municipal), municipal (prefectural), and county (city) levels, to enable dynamic and effective monitoring of such hazards ； 　　4. Rectify major hazard sources with defects and potential accident risks, urge production and operation units to increase investment, take effective measures to eliminate such risks, and ensure safe production. 　　5. Establish and improve regulations and policies regarding the monitoring of major hazard sources and the management of those with potential accident risks, and explore the creation of long-term mechanisms. 　　III. Scope of declaration and registration for major hazard sources A major hazard source refers to a unit (including sites and facilities) that permanently or temporarily produces, transports, uses, or stores hazardous substances in quantities equal to or exceeding the critical level. In accordance with the **Standards for Identifying Major Hazard Sources (GB18218-2000)** and the **Work Safety Law**, as well as the requirements of actual operations, the scope of registration for major hazard sources is as follows: 1. Tank storage areas (tanks) ； 　　2. Reservoir area (reservoir) ； 　　3. Production site ； 　　4. Pressure pipelines ； 　　5. Boiler ； 　　6. Pressure vessels ； 　　7. Coal mines (underground mining) ； 　　8. Underground mines for metals and non-metals ； 　　9. Tailings pond. 　　For the specific scope of application and registration, please refer to Attachment 1. 　　IV. Registration and Assessment of Major Hazard Sources 1. Production and business operations entities shall, in accordance with the Work Safety Law, the Guidelines for Identifying Major Hazard Sources (GB18218–2000), and the requirements regarding the scope of registration, register and document their major hazard sources, and fill out the Major Hazard Source Registration Form (see Attachment 2) to submit it to the local work safety supervision department (or coal mine safety inspection agency). 　　2. Production and business operation entities shall conduct a safety assessment of their major hazard sources at least once every two years, and issue a safety assessment report. Safety assessment work should be carried out under the supervision of registered safety assessors or registered safety engineers, or it can be entrusted to an assessment agency qualified for safety assessment. A safety assessment report should include basic information on major hazard sources, identification and analysis of hazardous and harmful factors, possible types and severity of accidents, the level of risk associated with major hazard sources, safety countermeasures, emergency rescue measures, and assessment conclusions. The safety assessment report shall be submitted to the local safety regulatory authority (or coal mine safety inspection agency) for record-keeping. 　　3. When there are significant changes in the production process of a major hazard source, as well as in factors such as materials, processes, equipment, protective measures, and the environment, or when **relevant regulations and standards change, the enterprise responsible for production and operation must conduct a new safety assessment of the major hazard source and report the relevant details to the local safety supervision department (or coal mine safety inspection agency). 　　V. Requirements for the supervision and management of major hazard sources 1. Safety supervision departments at all levels and coal mine safety inspection agencies must further enhance their awareness of the importance of supervising and managing major hazard sources. From the perspective of implementing the ** principle and serving the people, they should strengthen organizational leadership and supervision over the identification, assessment, monitoring, and control of such hazard sources, in order to effectively prevent serious and catastrophic accidents and safeguard the lives and property of the people as well as ensure the comprehensive, coordinated, and sustainable development of society and the economy ； Strengthening the supervision and management of major hazard sources should be regarded as an important aspect of safety production inspections, supervision, and evaluations, and it is necessary to organize these efforts properly and ensure their implementation. 　　2. Safety supervision departments at all levels and coal mine safety inspection agencies shall establish leadership teams and technical guidance teams for the supervision and management of major hazard sources, in order to provide unified leadership, coordination, and guidance for such supervision and management work within their respective jurisdictions. 　　3. Safety supervision departments at all levels and coal mine safety inspection agencies should step up supervision, inspections, and administrative law enforcement efforts, and urge production and business entities within their jurisdictions that possess major hazard sources to earnestly implement the relevant regulations and requirements regarding the supervision and management of such hazards, and to carry out comprehensive surveys, registrations, and monitoring activities for them. If inspections reveal that a production or business entity has failed to register and document major hazard sources, or has not carried out assessments or monitoring, nor established emergency response plans, strict action shall be taken in accordance with Article 85 of the Work Safety Law. Those responsible for serious or major accidents resulting from inadequate management and monitoring of major hazard sources, as well as delayed corrective actions, shall be held strictly accountable in accordance with the law by the persons in charge of the production and operation units and relevant personnel. 　　4. If safety supervision departments at all levels or coal mine safety inspection agencies discover potential accident hazards associated with major hazard sources during their inspections and supervision, they shall order the production and operation units to make immediate corrections ； If safety cannot be ensured before or during the rectification, the production and operation entity shall be ordered to evacuate workers from the hazardous area and to suspend production, operations, or use temporarily ； For those that cannot be rectified immediately, completion must be achieved within a set time limit, and effective preventive and monitoring measures must be taken. 　　5. Safety supervision departments at all levels and coal mine safety inspection agencies should strengthen publicity and training efforts regarding the declaration and registration of major hazard sources. They should carry out training in accordance with the textbook \"Declaration, Registration, and Management of Major Hazard Sources (Trial)\\" compiled by the **Bureau, so as to guide production and operation units in carrying out the declaration, registration, and management of such hazard sources. 　　6. To standardize the supervision and management of major hazard sources, all regions should uniformly use the information management system software for major hazard sources developed by the **Bureau to establish local databases of such hazards. Based on the distribution and risk level of these hazards, they should carry out targeted routine supervision, take appropriate measures to effectively prevent serious and catastrophic accidents, and ensure a steady improvement in the situation regarding work safety. 　　Attachments: 1.

Reply: 6# fallautumn is right; I’ve learned it

Oh my God! Such an old post has been brought up again. The 2009 version is currently used for the identification of major hazard sources. As for Document No. 56, we are gradually no longer using it; it has no meaning anymore.
