目的：指导负压二级生物安全实验室防护措施设计.方法：就全国各地实验室建造中的突出问题,结合工程实例,通过实验工艺、功能分区、平面布局、人流与物流组织、通风空调方式、气流组织、环境参数等关键因素分析,提出实施意见.结果：应设缓冲间;核心间/动物间形态宜规整;宜设更衣和准备间.宜采用直流系统;整体气流由清洁区流向核心/动物间,核心/动物间气流由相对清洁处流向污染源.气压梯度不小于10Pa;负压名义值:核心间,包括合并动物间的宜-20Pa;独立动物间宜-30Pa.结论：设计不仅应符合生物安全理念和实验工艺要求,而且应符合暖通、建筑等原理与要求.本文所提意见对科学建设实验室具有积极意义,并已在许多工程中得以验证.
