2020gmp指南换气次数
English Answer:
Ventilation Rates as per 2020 GMP Guidelines.
The 2020 GMP guidelines set forth by regulatory authorities establish specific ventilation rates for various areas within pharmaceutical manufacturing
facilities to ensure appropriate air quality and minimize the risk of contamination. These guidelines aim to maintain acceptable levels of airborne contaminants, prevent cross-contamination, and provide a suitable environment for product handling and manufacturing processes.
General Ventilation Requirements.
All areas within the manufacturing facility should be adequately ventilated to maintain acceptable levels of airborne contaminants.
The minimum ventilation rate for general areas is typically expressed in air changes per hour (ACH).
The ACH value represents the number of times the air volume in a room is replaced with fresh air per hour.
The required ACH varies depending on the specific area and its intended use. For example, higher ACH rates are required for areas where potent or cytotoxic substances are handled.
Specific Ventilation Requirements.
In addition to general ventilation requirements, the guidelines also specify ventilation rates for specific areas within the manufacturing facility, including:
Aseptic Processing Areas: These areas require high levels of cleanliness and controlled environmental conditions to prevent product contamination. The minimum ventilation rate for aseptic processing areas is typically 20 ACH.
Filling Areas: Filling areas where open product containers are exposed to the environment require a minimum ventilation rate of 15 ACH.
Warehousing Areas: Warehousing areas where finished products are stored require a minimum ventilation rate of 6 ACH.
Animal Housing Areas: Animal housing areas require specific ventilation rates to ensure adequate air quality for the animals and to minimize the risk of airborne contamination from animal dander or excreta.
Factors Influencing Ventilation Rates.
The required ventilation rate for a specific area depends on several factors, including:
The size of the room.
The occupancy level.
The type of activities performed.
The potential for contamination.
The presence of potent or cytotoxic substances.
Monitoring and Maintenance.
Regular monitoring of ventilation rates is essential to ensure compliance with GMP guidelines and to maintain acceptable air quality. Ventilation systems should be inspected, calibrated, and maintained regularly to ensure proper operation.

2020年版GMP指南换气次数。

2020年版GMP指南规定了制药生产设施内不同区域的具体换气次数，以确保适当的空气质量并最大程度地降低污染风险。

这些指南旨在维持可接受水平的空气污染物，防止交叉污染，并为产品处
理和制造工艺提供合适的环境。

一般换气要求。

制造设施内的所有区域应通风良好，以维持可接受水平的空气
污染物。

一般区域的最小换气次数通常以每小时换气次数（ACH）表示。

ACH值表示每小时房间中的空气体积被新鲜空气替换的次数。

所需的ACH值根据特定区域及其预期用途而异。

例如，处理强
效或细胞毒性物质的区域需要更高的ACH值。

具体换气要求。

除了一般换气要求外，指南还规定了制造设施内特定区域的换
气次数，包括：
无菌处理区，这些区域需要高度的清洁度和受控的环境条件，
以防止产品污染。

无菌处理区的最低换气次数通常为20ACH。

充填区，开放的产品容器暴露于环境中的充填区域需要最低15ACH的换气次数。

仓库区域，存放成品的仓库区域需要最低6ACH的换气次数。

动物饲养区，动物饲养区需要特定的换气次数，以确保动物有足够的空气质量，并最大程度地降低来自动物皮屑或粪便的空气污染风险。

影响换气次数的因素。

特定区域的所需换气次数取决于几个因素，包括：
房间的面积。

占用水平。

执行的活动类型。

污染可能性。

强效或细胞毒性物质的存在。

监测和维护。

定期监测换气次数对于确保符合GMP指南和维持可接受的空气质量至关重要。

应定期检查、校准和维护通风系统，以确保其正常运行。
