The Constructions of Safety Risk Assessment and Defense System in Chemical Experiment
A scheme for the construction of a safety risk assessment and defense system in chemical experiments is proposed.In the program,the safety risk assessment of experimental projects is carried out through risk factor analysis,and a redundant safety defense system is constructed.The safety risk classification and hierarchical control of the laboratory,together with the"three-level safety education"and standardized and institutionalized practical training,ensure the implementation of the safety defense system,so that the operators raise their awareness of safety protection and are able to comply with the safety operation procedures,which effectively safeguard the safety.
