Performance monitoring and analysis of Class Ⅱ biological safety cabinets in medical and health institutions in Beijing
Objective To understand the performance of Class Ⅱ biological safety cabinets and its influencing factors in medical and health institutions in Beijing,and to provide reference for implementing refined management.Methods The instrument testing method was used to detect and analyze the performance indicators of Class Ⅱ biological safety cabinets in 39 medical and health institutions in Beijing.Results A total of 309 domestic and imported biological safety cabinets were tested,with a comprehensive qualified rate of 61.2%.The performance indicators of domestic and imported products were basically the same.The comprehensive qualified rate of A2 type biological safety cabinets with a service life of less than 10 years was relatively high.The main factors affecting the qualified rate of biological safety cabinets were the lack of performance testing equipment,insufficient professional personnel inspections,and the absence of professional testing institutions for annual inspections.Conclusions The comprehensive qualified rate of domestic and imported biological safety cabinets in medical and health institutions in Beijing is comparable,and the configuration of domestic biological safety cabinets should be increased.Therefore,it is necessary to strengthen the supervision and monitoring of biological safety cabinets and improve their safety protection performance.
