注意看FDA 指南Sterile Drug Products Produced by Aseptic Processing —Current Good Manufacturing Practice 2004原文
要求12.5Pa的房间指的是普通区(无洁净级别)和无菌工艺房间(理解为至少B级区)之间(按行业设计理念,核心无菌区肯定是最高压,相比普通区的压差绝大部分是大于12.5Pa的),比如灌装间轧盖后直接通过传输通道到普通区。并不是任意的不同洁净级别房间之间的压差,更不是同洁净级别房间。
原文:
In some cases, the aseptic processing room and adjacent cleanrooms have the same classification.
Maintaining a pressure differential (with doors closed) between the aseptic processing room and
these adjacent rooms can provide beneficial separation. In any facility designed with an unclassified
room adjacent to the aseptic processing room, a substantial overpressure (e.g., at least 12.5 Pa) from
the aseptic processing room should be maintained at all times to prevent contamination. If this
pressure differential drops below the minimum limit, it is important that the environmental quality
of the aseptic processing room be restored and confirmed. |
