生物安全柜运行现状调研

Investigation on operation status of biosafety cabinets

汇总整理了2013-2015年度共计962台生物安全柜的现场实测数据,结合国内外用于评价生物安全柜综合性能的相关标准进行分析,发现安全柜的竖直气流平均风速、工作窗口进风平均风速、噪声及送排风高效过滤器检漏等各检测参数按照不同的评价标准其合格率存在明显区别。出于对产品质量及生物安全风险的控制,国内外部分标准分别对安全柜操作台面洁净度、竖直风速均匀性、报警和连锁功能验证均提出了特殊的要求。统计数据显示了目前我国安全柜使用现状,为后期我国生物安全柜标准修编过程中所需检测项目以及评价指标的确立提供必要的数据支持。

Collects and summaries the measured data of 962 biosafety cabinets（BSCs） from 2013 to 2015. Evaluates the comprehensive performance of BSCs according to the international and Chinese standards, which shows that the pass rate of BSCs＇ average vertical air velocity, average supply air velocity, noise level and HEPA filter leak are obviously different from each other according to different standards. For controlling the product quality and biological safety risk, some standards put forward special requirements on platform cleanliness, uniformity of vertical air velocity, alarm and fan interlock function. The statistical data analysis shows the current situation of the biosafety cabinets applied in China, which provides the necessary data support for the establishment of test item and evaluation index in the further revision process of the biosafety cabinet standard in China.
