What types of chemical enterprises need to conduct safety pre-assessments?

According to **Order No. 8 of the State Administration of Work Safety, ‘Implementation Measures for Safety Permits for Hazardous Chemicals Construction Projects’, Article 7: Before applying for a safety review for the establishment of a construction project, the project owner shall select a qualified safety assessment agency to conduct a safety assessment of that project. 　　The following construction projects shall undergo safety assessments by Class A safety assessment agencies: (1) those approved (authorized, registered) by the State Council and its investment authorities ； 　　(II) Those approved (authorized, registered) by the people’s ** of provinces, autonomous regions, and municipalities directly under the Central Government and their investment authorities ； 　　(III) Those producing highly toxic chemicals ； 　　(IV) Across provinces, autonomous regions, and municipalities directly under the Central Government ； 　　(5) Where there are special requirements from the State Administration of Work Safety and the work safety supervision and management departments of the people’s governments of provinces, autonomous regions, and municipalities directly under the Central Government. 　　Article 8 Safety assessment agencies shall conduct safety assessments of construction projects in accordance with relevant laws, regulations, rules, and standards regarding work safety, and shall be responsible for the safety assessment reports prepared for such projects. 　　The safety assessment report for a construction project includes the following main contents: (1) Overview of the construction project ； 　　(II) Physicochemical property parameters of raw materials, intermediate products, final products, or stored hazardous chemicals ； 　　(III) Technical requirements for the packaging, storage, and transportation of hazardous chemicals ； 　　(IV) Hazardous and harmful factors of construction projects and their degree of hazard and harm ； 　　(5) Safety conditions for construction projects ； 　　(VI) Major technologies, processes, methods, as well as devices, equipment, and facilities and their safety and reliability ； 　　( VII) Safety countermeasures and recommendations.

Hazardous chemicals, as referred to by the Safety Supervision Bureau, are those chemicals that are products, intermediates, or raw materials in the production process and are listed in the hazardous chemicals catalog. They are divided into eight categories. Any enterprise that uses, stores, or produces hazardous chemicals during its operations is considered a hazardous chemicals enterprise, and it must obtain safety permits in accordance with the requirements outlined in Document No. 8; one of these requirements is a safety pre-assessment. Therefore, whether a pre-assessment is conducted or not is not directly related to the classification of fire hazard. Of course, few chemicals of Category C are included in the list, but it is not ruled out that these chemicals may have other hazardous properties as well.

Category C is a description in building codes of the fire hazards associated with certain materials. To determine whether such materials are hazardous chemicals, it is necessary to check the list of hazardous chemicals; if they are indeed hazardous chemicals, then a safety pre-assessment must be conducted

Generally, chemical enterprises are required to conduct safety assessments, mainly because if any of the raw materials, products, or semi-finished goods are hazardous substances, then the enterprise is considered a hazardous chemicals enterprise; this also applies to exhaust gases and wastewater. Due to their flammability, explosiveness, and toxicity, it is difficult for chemical companies to avoid conducting safety assessments.

The basis for conducting a safety assessment is not the fire hazard; please clarify this concept, OP. Enterprises that produce hazardous chemicals (by hazardous chemicals, I mean those listed in the 2002 version of the Hazardous Chemicals Catalogue) must conduct preliminary assessments and inspections to obtain a safety production license, and must carry out assessments of their current operating conditions every two years. For those who use hazardous chemicals but do not engage in production, pre-assessment and acceptance are sufficient, and there is no need to obtain a work safety license. Assess the current situation every two years. If highly toxic substances are involved, whether in use or production, a preliminary assessment is required, as well as approval to obtain a safety production license; in addition, a safety evaluation must be conducted once a year. I’m new to this forum, and I’m not sure if such an answer will meet the original poster’s requirements.

Generally, all new, modified, or expanded projects require a safety pre-assessment. If the project involves the production of hazardous chemicals, a safety facility assessment is necessary. It depends on whether your product is listed in the 2002 version of the \"List of Hazardous Chemicals\"

Fire protection design and safety assessment are two distinct areas; please consider them separately. Fire protection design should primarily refer to the Regulatory Guidelines, as the fire department’s design review also relies on these as its main basis. To determine whether a safety pre-assessment is required, reference should be made to the \"Implementation Measures for Safety Licensing of Hazardous Chemicals Construction Projects.\" In general, whenever the project process involves substances listed in the \"Catalogue of Hazardous Chemicals,\" it is necessary to engage a safety assessment agency to conduct a safety pre-assessment. It should be noted that when commissioning a safety pre-assessment, the assessment fee can be adjusted based on the level of hazardous materials involved in the project and the difficulty of the assessment. Safety assessment is inherently a task with poor cost-effectiveness that still has to be carried out; efforts should be made to spend as little money as possible.

a) Petroleum processing industry； b) Chemical raw materials and chemicals manufacturing industry ； c) Pharmaceutical manufacturing industry ； d) Gas production and supply industry ； e) Coking industry.

Follow local regulations; in some places, the rules are quite lenient! Talk to the local safety supervision and economic trade authorities

Both new projects and expansion projects require a preliminary evaluation during the project design review phase. HAZOP analysis is used abroad, and although it is less utilized in China, it is expected to be widely adopted in the future

Thank you for the detailed explanation. I study environmental engineering; I have worked in a company for three years and now I want to switch to working in the field of evaluation. I have sought advice, and I hope everyone will be willing to help me in the future. Thank you in advance
