In order to implement the “Opinions on Comprehensively Strengthening the Safety Production of Hazardous Chemicals” issued by the General Office of the CPC Central Committee and the General Office of the State, strengthen the management and control of safety production risks in fine chemical enterprises, and effectively prevent major accidents, the National Standard “Fine Chemical Industry” organized by the Ministry of Emergency Management was formulated Response Security Risk Assessment Specification (GB/T 42300-2022) has been recently released and implemented.

At present, fine chemical production is mostly intermittent or semi-intermittent reactions. The raw materials, intermediate products and product varieties and processes are complex and diverse. The reaction process is accompanied by a large amount of heat release, which has the risk of losing control easily, leading to fires, explosions, and poisoning accidents. main reason. By carrying out safety risk assessment of fine chemical reactions, the risk level of the reaction process is determined, effective risk control measures are adopted, and safety design is carried out in accordance with the recommendations of the reaction safety risk assessment, the level of automation control is improved, the level of intrinsic safety is improved, and safe operating conditions are clarified. It is of great significance to ensure the safe production of fine chemicals.

The “Specifications for Safety Risk Assessment of Fine Chemical Reactions” is based on further absorbing the advanced practical experience in the development of the fine chemical industry at home and abroad, and elevates the “Guiding Opinions on Strengthening the Safety Risk Assessment of Fine Chemical Reactions” to a national standard. The standard clarifies the scope of application, key assessment objects, and stipulates the requirements for safety risk assessment of fine chemical reactions, basic conditions for assessment, data testing and acquisition methods, and assessment report requirements. The standard aims to perceive, evaluate, and prevent and control risks, and establishes a quantitative assessment standard system for reaction process hazard levels. Based on different reaction process hazards, it also proposes relevant aspects such as process optimization design, regional isolation, and personnel safety operations. Suggestions on security risk prevention and control measures. The implementation of this standard will effectively promote fine chemical companies to strengthen their safety risk assessment and support the prevention and control of major safety risks in fine chemicals.
