26、gowning steps must be separate,气锁设计 Air Lock Design,更衣前后段要分开设置，不在同一个区域内，并且穿洁净衣房间按气锁设计，连锁门和压差控制。Air lock design for gowning room with door interlock and pressure control由于按气锁设计，且静态级别与生产区一致，因此更衣最后的缓冲间可以取消（某些情况下由于男女更衣室布置需要，可以保留，但不是必须)。Buffer room after 2nd gowning not required,更衣分级 Clean Class for Gown

27、ing,更衣后段的洁净级别，与其服务的洁净生产区的静态级别相一致（无动态要求）Clean class of 2nd gowning room is equal to production area at rest更衣前段不定级，但需送入经过 HEPA 过滤的洁净空气，有一定的换气次数（可视所服务的生产区级别的不同，分别参照C级或D级标准设计），但不定级。前段和后段之间要保持合理的气流流向和压差。Clean air is preferred for 1st gowning area,with reliable air pattern and pressure different controls

28、,退出通道 Leaving Way,GMP第30条要求：必要时，可将进入和离开洁净区的更衣间分开设置。Entering/Leaving changing rooms can be separately if necessary 什么是必要时？What is necessary?退出时衣服上所带微粒和微生物污染洁净更衣区 Change room may be contaminated by the particles and microbe with the clothes生产操作产生的有害物质通过更衣区外溢；To avoid polluted air blow out from process
