style=";font-family:宋体;font-size:14px">　　二级生物洁净安全柜（也称为二级生物安全柜）的预防性维护周期与更换标准对于确保实验室生物安全至关重要。以下是对其维护周期与更换标准的详细阐述：</span></p><p><span style=";font-family:宋体;font-size:14px">　　一、预防性维护周期</span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">1.</span><span style="font-family:宋体">日常清洁：</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　实验结束后，应立即清除可见残留物（如溢出液滴、培养物残渣、粉尘）及表面污染。使用无菌蒸馏水湿润的无绒软布轻柔擦拭工作台面、内壁（侧壁、后壁、顶部）、玻璃窗内表面及任何溅洒区域。</span></p><p><span style=";font-family:宋体;font-size:14px">　　若处理过传染性物质或存在潜在污染，必须升级为消毒程序。</span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">2.</span><span style="font-family:宋体">定期消毒：</span></span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　每周对工作区所有表面进行消毒，杀灭可能存在的微生物。使用经批准的、对目标微生物有效且兼容二级生物洁净安全柜材质的消毒剂（如</span><span style="font-family:Calibri">70%</span><span style="font-family:宋体">乙醇或异丙醇，或稀释漂白剂如</span><span style="font-family:Calibri">10%</span><span style="font-family:宋体">溶液），作用规定时间后，用无菌水去除残留。</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　发生重大溢出事件（尤其涉及高风险病原体）时，需进行更严格的消毒，并涵盖所有步骤。</span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">3.</span><span style="font-family:宋体">预防性维护检查：</span></span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　通常每</span><span style="font-family:Calibri">6-12</span><span style="font-family:宋体">个月进行一次预防性维护检查，或依据厂商建议及风险评估结果确定。</span></span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　检查内容包括但不限于：高效过滤器完整性、气流速度、负压</span><span style="font-family:Calibri">/</span><span style="font-family:宋体">换气次数、气流的烟雾模式以及警报和互锁系统等。</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　二、更换标准</span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">1.</span><span style="font-family:宋体">初效过滤器：</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　主要拦截大颗粒粉尘，易堵塞，需定期维护。</span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　一般建议每</span><span style="font-family:Calibri">3-6</span><span style="font-family:宋体">个月清洗（可重复使用材质）或直接更换（不可清洗型），具体根据使用环境和脏污程度调整。</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">2.</span><span style="font-family:宋体">中效过滤器：</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　过滤中等颗粒，?；じ咝Ч似?。</span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　寿命通常为</span><span style="font-family:Calibri">6-12</span><span style="font-family:宋体">个月，接近寿命末期时会观察到压差上升或效率下降，此时需更换。</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">3.</span><span style="font-family:宋体">高效过滤器（</span><span style="font-family:Calibri">HEPA</span><span style="font-family:宋体">）：</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　过滤效率较高，寿命较长。</span></p><p><span style=";font-family:宋体;font-size:14px"><span style="font-family:宋体">　　常规建议每</span><span style="font-family:Calibri">1-3</span><span style="font-family:宋体">年更换，但需结合性能检测（如年度粒子扫描检漏、气流速度或压差变化）决定。出现泄漏或效率不达标时，必须强制更换。</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　<span style="font-family:Calibri">4.</span><span style="font-family:宋体">紫外灯：</span></span></p><p><span style=";font-family:宋体;font-size:14px">　　用于对工作台面、侧壁表面以及后壁内侧进行杀菌处理。</span></p><p><span style=";font-family:宋体;font-size:14px">　　建议每年更换一次，以确保其杀菌效果。</span></p><p><span style=";font-family:宋体;font-size:14px">　　二级生物洁净安全柜的预防性维护周期与更换标准应严格遵循操作风险等级与实际使用强度两大核心原则，形成层级化的维护体系。通过定期的清洁、消毒、预防性维护检查以及必要的过滤器更换，可以确保生物安全柜的持续有效运行，为实验室人员和环境提供安全保障。</span></p><p> </p> </div> </div>
