To further improve the safety risk awareness of all laboratory staff, to better identify the safety risk factors around them, and to eliminate potential safety hazards, the Party Branch of Extreme Environmental Polymer Materials organized a series of activities from April to June. From April to June, the party branch of Extreme Environment Polymer Materials organized a series of activities, such as "All Staff Participate, Zero Hidden Safety Hazards" quiz, laboratory self-inspection and mutual safety inspection in the laboratory. 

　　Laboratory staff and students actively responded to and participated in the "All Staff Participate, Zero Safety Hazards" quiz, returning 186 valid answers, which showed that everyone had a good grasp of basic safety issues, with a correct rate of over 90%. At the same time, we also put forward 81 questions and suggestions for safety management in the institute, laboratory and subject groups, covering various aspects such as public environment, laboratory facilities, laboratory items placement, safety inspection, operation requirements, garbage classification, personal protection, etc. Among them, there are high concerns about various emergency and safety training, strengthening inspection, regular inspection, strengthening infrastructure, and strengthening standard operation and maintenance of equipment. The party branch has organized and fed back the relevant issues to the subject groups, laboratories and relevant departments of the Institute of Chemistry. 

　　In addition, the party branch has organized safety officers and student representatives to conduct self-inspection and mutual inspection, and emphasized the problems that are easily neglected in practical operation, such as waste liquid cleaning, garbage classification, electrical safety, and the arrangement of items without dead ends. The party branch will further form a system of irregular inspections and safety training to ensure that research activities are carried out safely and efficiently.
