Lab Risk Classification and Tiered Safety Control System for University Labs
From routine lab tests with ethanol to high-risk operations involving lethal toxic chemicals and radioactive sources, hazard risks vary dramatically across different laboratory settings. To accurately identify, assess, and control diverse lab hazards, educational and research institutions worldwide have gradually established standardized laboratory safety management frameworks. China has also developed a comprehensive tiered risk control system that serves as a practical reference for global lab safety governance. In March 2024, the Ministry of Education of China officially put into effect the Administrative Measures for Classification and Risk Grading of University Laboratory Safety (Trial) , which categorizes university laboratories into four risk grades (Grade Ⅳ, Ⅲ, Ⅱ, Ⅰ) marked with four universal warning colors: Blue, Yellow, Orange, and Red.
