4.12 Airlocks should be designed and used to provide physical separation and to minimize microbial and particle contamination of the different areas and should be present for material and personnel moving between different grades. Wherever possible, airlocks used for personnel movement should be separated from those used for material movement. Where this is not practical, time-based separation of movement (personnel/material) by procedure should be considered. Airlocks should be flushed effectively with filtered air to ensure that the grade of the cleanroom is maintained. The final stage of the airlock should, in the “at rest” state, be of the same cleanliness grade (viable and total particle) as the cleanroom into which it leads. The use of separate change rooms for entering and leaving the grade B area is desirable. Where this is not practical, time-based separation of activities (ingress/egress) by procedure should be considered. Where the CCS indicates that the risk of contamination is high, separate change rooms for entering and leaving production areas should be used. Airlocks should be designed as follows:
气闸的设计和使用应提供物理隔离并最大限度地减少不同区域的微生物和颗粒污染,并且应为在不同等级之间移动的材料和人员提供气闸。在可能的情况下,用于人员移动的气闸应与用于材料移动的气闸分开。如果这不切实际,则应考虑按程序按时间分隔移动(人员/材料)。应使用过滤空气有效冲洗气闸,以确保保持洁净室的等级。气闸的最后阶段应在“静止”状态下与其通向的洁净室具有相同的清洁度等级(活颗粒和总颗粒)。最好使用单独的更衣室进出 B 级区域。如果这不切实际,则应考虑按程序对活动(入口/出口)进行基于时间的分离。 如果CCS 表明污染风险很高,则应使用单独的更衣室进入和离开生产区域。气闸应设计如下:
i. Personnel airlocks: Areas of increasing cleanliness used for entry of personnel (e.g. from the grade D area to the grade C area to the grade B area). In general hand washing facilities should be provided only in the first stage of the changing room and not be present in changing rooms directly accessing the grade B area.
人员气闸:用于人员进入的提高清洁度的区域(例如,从 D 级区域到 C 级区域到 B 级区域)。一般而言,洗手设施应仅在更衣室的第一阶段提供,而不应设置在直接进入 B 级区域的更衣室中。
ii. Material airlocks: used for materials and equipment transfer.
物料气闸:用于物料和设备的转运。 |
