The process safety management of chemical enterprises involves the whole process of production, storage, use, disposal or handling of hazardous chemicals, or equipment maintenance, maintenance, overhaul and process changes related to these activities. It is the basis of safe production in chemical enterprises, the core of process safety management in chemical enterprises, and an important premise to eliminate and reduce the harm of process and reduce the consequences of accidents. Safety supervision departments at all levels should attach great importance to the safety management of chemical production processes, urge hazardous chemical production enterprises to strengthen the safety management of chemical processes, establish a chemical process safety system, conduct process safety analysis on a regular basis, identify and demonstrate the safety and reliability of chemical production processes of enterprises to be adopted for the first time in China, ensure the safety of chemical production processes, and effectively prevent and reduce accidents.
Second, strengthen the process safety management of chemical enterprises.
Safety supervision departments at all levels should urge chemical enterprises to strengthen chemical process safety management in accordance with the requirements of the Implementation Guidelines for Process Safety Management of Chemical Enterprises (AQ/T3034-20 10): First, establish and improve process safety information files. Including process safety, process technology, process equipment, process hazards, as well as process system transformation, factory design, production operation, equipment and facilities maintenance experience and lessons and other related information files; The second is to carry out process hazard analysis regularly. Enterprises should carry out process hazard analysis during the construction of processing plants to identify, evaluate and control the hazards related to process systems, and then reconfirm and update them every three years. The third is to establish and implement the training management system. According to the post characteristics and skills of employees, formulate and implement on-the-job training plans to ensure that employees master process safety knowledge and have corresponding safety skills. The fourth is to strengthen the maintenance and management of equipment and facilities. Enterprises should establish and implement preventive maintenance procedures and conduct planned tests and inspections on key process equipment; Implement work permit management for risky work, keep work tickets, and understand the implementation situation in order to continuously improve. Fifth, strengthen enterprise change management. Strengthen the planned control of permanent or temporary changes in chemicals, processes, equipment, procedures and operating processes to ensure personal and property safety. Sixth, strengthen emergency management. Establish an emergency response system and conduct emergency drills regularly.
Three, standardize the management of newly developed chemical production process
The newly developed production process of hazardous chemicals must be gradually extended to industrial production on the basis of small-scale, pilot-scale and industrial tests. The pilot and expanded test devices involving hazardous chemicals (including raw materials and intermediate products) and chemical production processes used for the first time in China must be demonstrated for safety. The identification and safety demonstration of chemical production technology used for the first time in China shall be applied by the enterprise to the Provincial Safety Supervision Bureau, which shall entrust the Provincial Chemical Society to organize the demonstration. The enterprise applying for demonstration (certification) shall submit the test report or technical feasibility report of process, technology and products, process technical description, safety risk analysis, patents, standards or novelty retrieval reports and other relevant documents and materials. The Provincial Society of Chemistry and Chemical Engineering should organize experts in technology, safety and environmental protection to form an expert group to demonstrate according to the application documents and materials submitted by the enterprise. Need to go to the site for verification, it shall conduct on-site verification, objectively and fairly issue written argumentation opinions of the expert group to the provincial safety supervision bureau, and keep the enterprise secrets.
