Research on the Storage Management of Explosive-Precursor Chemicals in Engineering University Laboratories

This study systematically analyzes the physicochemical properties and safety risks of 32 categories of explosive-precursor chemicals commonly used in engineering university laboratories. By examining 127 laboratory accident cases reported by the Ministry of Education from 2019 to 2023, it reveals the correlation between management loopholes and accidents. Based on the Regulations on the Safety Management of Hazardous Chemicals and the GB 15603-2022 General Rules for the Storage of Common Hazardous Chemicals, a graded classification storage model and a dynamic supervision system are proposed. The results demonstrate that implementing intelligent storage cabinets and RFID traceability systems can reduce the risk of non-compliant operations by 85%, while establishing a "five-in-one" management system improves the laboratory safety hazard rectification rate to 98.6%. This research provides a standardized solution for the management of hazardous chemicals in university laboratories.
