Safety is the basic guarantee for university laboratories to carry out teaching and research.The dual prevention mechanism with risk classification control and hidden danger investigation and management as the core can effectively curb the occurrence of laboratory safety accidents.This paper describes the four stages of building a dual prevention mechanism,and uses the operating condition risk assessment method(LEC)to evaluate and grade laboratory risks,moving the threshold of laboratory risk management and control to the risk point classification management and control,and building a solid laboratory safety defense line.
