Fire protection design standards for fine chemical enterprises: Two major chemical-producing provinces provide their responses!
Thread Content
1. For the fire protection design of new, expanded, or renovated projects in fine chemical enterprises, the \"Fire Protection Design Standards for Engineering Designs of Fine Chemical Enterprises\" (GB51283-2020) shall apply. The design unit shall select the strictest safety provisions based on the characteristics of the hazard sources in the construction project. II. In accordance with the \"Reply from the General Office of the **State Administration for Work Safety on the Criteria for Identifying Chemical ProjectsWith Explosive Hazards\" (An Jian Zong Ting Guan San Han [2014] No. 5), for construction projects with explosive hazards, the evaluation and design agencies shall conduct an analysis of such explosive hazards. For units that constitute major hazard sources or involve nitration-based chemical processes, the fire separation distance from surrounding buildings and structures must meet the requirements set out in the \"Code for Fire Protection Design of Petrochemical Enterprises\" (GB50160). For the units mentioned above that are outdoor installations or located within open or semi-open structures, the starting and ending points of the fire separation distance are determined based on the outer edges of Class A and Class B equipment ； The starting and ending points of the fire separation distance for enclosed factories are the outermost axis of the building (in the case of Class A or B equipment located outside the building, the outer edge of such equipment serves as the reference) ； For storage tanks or tank groups, the outer wall of the tank serves as the starting and ending point for the fire separation distance. III. For the explosion-hazardous units that have already been constructed and constitute major hazard sources or involve nitration chemical processes, if the fire separation distances from other buildings within the enterprise meet the requirements of the original design standards and specifications, but do not comply with the \"Design Fire Protection Standards for Petrochemical Enterprises\", then a qualified evaluation or design agency is required to re-assess these distances, and quantitative risk analysis must be conducted to determine the safe distances between various installations and facilities ； If the safety distance does not meet the requirements, safety measures such as reducing the amount of hazardous chemicals on site and implementing effective explosion prevention (or relief) measures, which must be approved by the evaluation or design agency, should be adopted. In cases involving the construction or renovation of buildings, proper design is necessary to ensure that the safety risks remain within acceptable levels. IV. If the existing factory buildings, warehouses, or storage tanks of an enterprise are designed in accordance with the standards and specifications applicable at that time, and do not constitute major hazard sources nor involve nitration-based hazardous chemical processes, the enterprise may use these existing facilities for technical upgrades that do not involve major hazard sources or nitration processes; any new installations and equipment must meet the requirements of current standards and specifications.

We have received your suggestion titled \"Suggestions on Further Clarifying the Construction Standards Applicable to Fine Chemical Enterprises\", and our response is as follows: First of all, thank you for your concern and support for work related to safe production! In response to your question regarding the applicable standards for the construction regulations of fine chemical enterprises, the Provincial Emergency Management Department has attached great importance to this issue, organizing special meetings to develop work plans, clarify and detail specific measures, and ensure their implementation. The issue of applicable standards for the construction specifications of fine chemical enterprises is a common challenge faced by chemical companies in our province. In accordance with the \"Notice from the State Administration of Work Safety and the Ministry of Housing and Urban-Rural Development on Further Strengthening the Safety Design Management of Hazardous Chemicals Construction Projects\" (An Jian Zong Guan San [2013] No. 76), hazardous chemicals construction projects that fall under the category of \"two key areas and one major project\" or those with explosion risks must meet the requirements of current standards and regulations such as the \"Code for Fire Protection Design of Buildings\" and the \"Code for Fire Protection Design of Petrochemical Enterprises\", with the strictest safety provisions taking precedence. Given that this issue involves various aspects such as licensing and regulation, and requires a high level of expertise, the Provincial Emergency Management Department has established a task force composed of relevant departments and experts to focus on studying and resolving the problems related to the application of standards for hazardous chemicals construction projects. From April 8th to 9th, personnel selected from the task force were assigned to form a research team that went to fine chemical enterprises such as Weizhi Pharmaceutical Co., Ltd. and Tengzhou Ruiyuan Flavoring Co., Ltd. to conduct investigations. Symposia were held to hear about and understand the current situation, existing problems, and suggestions of these enterprises regarding the application of standards, and discussions were also held with the Zaozhuang Emergency Management Bureau, the Tengzhou Emergency Management Bureau, as well as relevant planning and design firms and safety assessment organizations. Article 17 of the Work Safety Law of the People’s Republic of China stipulates: “Production and business operation entities shall meet the work safety conditions prescribed by this Law, as well as relevant laws, administrative regulations, and **standards or industry standards” ； Those that do not meet the conditions for safe production shall not engage in production and business activities. ”In 2018, the Ministry of Housing and Urban-Rural Development revised the \"Code for Fire Protection Design of Buildings\" (GB50016) and the \"Fire Protection Design Standards for Petrochemical Enterprises\" (GB50160). These standards specify their scope of application and include mandatory provisions. In January 2020, the Ministry of Housing and Urban-Rural Development formulated and issued the \"Fire Protection Standards for Engineering Design of Fine Chemical Enterprises\" (GB51283), which came into effect on October 1, 2020. Based on the current laws, regulations, rules, and standards, and taking into account the results of relevant investigations, enterprises shall be guided and urged to strictly comply with the applicable provisions. Regarding the application of engineering design standards in fine chemical enterprises, **where the standards set clear requirements, those requirements must be strictly followed** ； In the absence of specific requirements, refer to Document No. **76** for implementation. The Provincial Emergency Management Department will use your proposal as an opportunity to step up efforts in promoting and implementing the newly issued standards, urge enterprises to strictly abide by laws, regulations, standards, and procedures related to work safety, and facilitate the safe and high-quality development of these enterprises. We earnestly request that you continue to show your concern and support for work related to safe production, and offer your valuable suggestions to help us identify problems, improve our work, and advance the overall level of safe production across the province!

The news that the \"Fire Protection Design Standards for Fine Chemical Enterprise Engineering\" (GB 51283-2020) has been officially released and will come into effect on October 1st has drawn widespread attention within the industry. What are the differences between this standard and the Code for Fire Protection Design of Buildings GB 50016, as well as the Fire Protection Design Standard for Petrochemical Enterprises GB 50160? What key aspects should fine chemical enterprises pay attention to? Background: This measure is driven by the relatively low inherent safety levels of fine chemical enterprises, the frequent occurrence of accidents, and the lack of specific regulatory standards for safety management in the field of fine chemicals in China. In the engineering design process, design is generally carried out with reference to the \"Code for Fire Protection Design of Buildings\" GB 50016 (hereinafter referred to as GB 50016) and the \"Fire Protection Design Standards for Petrochemical Enterprises\" GB 50160 (hereinafter referred to as GB 50160). For a long time, there has been ambiguity in society regarding whether GB 50016 or GB 50160 should be applied to fine chemical projects; the standards used in design have been rather chaotic, which has resulted in insufficient fire separation distances in many construction projects and posed risks to production safety. The issuance of the \"Fire Protection Design Standards for Engineering Projects in Fine Chemical Enterprises\" (GB 51283-2020) (hereinafter referred to as GB 51283) provides a standard upon which compliance can be based in the fire protection design process for such engineering projects. It will further standardize the engineering design of fine chemical enterprises, ensure personal and property safety, and promote the healthy and sustainable development of the industry. The first focus of the standard is to establish the principles for setting fire separation distances. The production facilities of fine chemical enterprises are mostly operated in enclosed or semi-enclosed buildings or frame-type units, while raw materials are generally stored outdoors in tanks; the finished products are also usually stored in warehouses in barrels or bags. Therefore, in setting fire separation distances, GB 51283 aims to comply with the requirements of GB 50016 while also taking into account the provisions of GB 50160, thereby establishing unified standard requirements. Second, the safety requirements for the manufacturing process have been refined. Fine chemical production processes vary in terms of their processes, risk characteristics, and control methods; simply applying the general requirements of GB 50160 is insufficient to meet the specific safety demands of these processes. Therefore, GB 51283 sets out specific design requirements regarding the intrinsic safety of process facilities, including measures such as pressure relief, explosion protection, flame arrestment, and emergency cooling. Third, it emphasizes the risks posed by non-electrical equipment. The production workshops of fine chemical enterprises are usually quite small in size; once materials leak, they do not spread easily. Flammable vapors can easily cause explosions when exposed to sparks. In addition to sparks from electrical installations, the sparks that cause explosions can also arise from mechanical friction or contact-induced vibrations in pumps, fans, and pipelines. The risk of sparks generated by non-electrical equipment is often overlooked. Fourth, management requirements for different risk levels have been introduced. Determining the hazard level of fine chemical processes is in line with the requirement stated in the \"Guiding Opinions on Strengthening the Risk Assessment of Safety in Fine Chemical Reactions\" (Document No. An Jian Zong Guan San [2017] No. 1), which specifies that fine chemical enterprises must conduct reaction risk assessments. Through such assessments, the hazard level of the production processes can be determined, and the design requirements for safety instrument systems can be established based on that hazard level. Fifth, it incorporates the content related to the safety integrity level of safety instruments. The configuration of safety instrument systems and their safety assessment in chemical enterprises are primarily specified in the \"Code for Design of Safety Instrument Systems in Petrochemical Industries\" (GB/T 50770) and \"Functional Safety of Safety Instrument Systems in the Process Industry\" (GB/T 21109). Relevant provisions are incorporated into GB 51283, which stipulates that during the design phase it is necessary to verify the safety integrity level of the installed safety instrument systems, and to determine the requirements regarding their safety and reliability based on the results of such verification. Scope of application: GB 51283 specifies the conditions under which this standard applies, and it is only applicable to fine chemical enterprises whose storage facilities do not exceed the specified scale. This standard does not apply to those exceeding the specified storage scale. This allows normal production in fine chemical enterprises while effectively controlling risks and preventing the spread of accidents.
Thank you for sharing. As a fine chemical company, we need to adapt to the new regulations
The rollout of the new standards is about to begin! The editor-in-chief is giving a lecture! Those who need it can message me privately and leave their contact information!
