目的了解某单位实验室生物安全柜运行现状及其防护性能。方法共调查14台Ⅱ级生物安全柜的使用情况,依据YY 0569-2011标准进行物理性能指标检测。结果对外观完整性、高效过滤器完整性、噪声、照度、振动、下降气流流速、流入气流流速、气流模式8个项目进行检测,合格率分别为100%、93%、100%、79%、93%、93%、79%和86%。结论该单位部分正在使用的生物安全柜性能检测不合格,应加强日常维护和定期性能检测,及时排除存在生物安全隐患,防止实验室感染事故发生。
Objective To understand the operation status and protective performance of a unit laboratory biological safety cabinet. Methods A total of 14 Class II biological safety cabinets were investigated for their use, and their physical properties were tested according to YY 0569-2011 standard. Results Eight items including appearance integrity, high efficiency filter integrity, noise, illumination, vibration, descending airflow rate, inflow airflow rate and airflow pattern were tested. The pass rates were 100%, 93%, 100%, 79% 93%, 93%, 79% and 86%. Conclusion The biosafety cabinets that are being used in some units of this unit failed to perform their performance tests. Routine maintenance and regular performance testing should be strengthened to eliminate potential biosafety risks in a timely manner and prevent laboratory infection accidents.
