How to control the flow of personnel and goods in clean rooms?

A cleanroom is a room that controls the concentration of organisms and particulate matter in the environment, and is typically used in industries that require highly clean environments, such as pharmaceuticals, biotechnology, microelectronics and food processing. In a clean room, the movement of people and goods is a key environmental control factor and stringent measures need to be taken to ensure the cleanliness of the clean room. This paper will discuss how to control the movement of people and goods in cleanrooms.
First, the clean room personnel flow control
1, personnel training: into the clean slaughter of all personnel to carry out rigorous training, including the clean rate regulations child system, personal protective equipment, the wear comparison, the correct entry and exit procedures.Ensure that all personnel understand the importance of the clean room and their role in the base.
2. Cleanroom personnel access control: Establish air gates between cleanrooms and non-clean areas to control the number of personnel entering the cleanroom and to reduce the acquisition of external particulate matter.
3. Personal Protective Equipment (PPE): All personnel entering the cleanroom must wear appropriate personal protective equipment (PPE) such as clean suits, hats, face masks, etc. to prevent them from bringing external contaminants into the cleanroom.
4、Periodic physical examination: Establish a system of periodic physical examination of personnel before entering the cleanroom to ensure the health status of personnel and reduce the impact of disease on the cleanroom environment.
5, flow control: according to the cleanliness requirements of the clean room, the movement of personnel in the clean room and stay time restrictions, to reduce the factors that may cause environmental pollution.
Second, the clean room goods flow control 1, goods cleaning treatment; all goods into the clean rate must undergo strict cleaning treatment, including surface cleaning, disinfection, vacuum drying and other steps to ensure that it does not bring external micro-organisms and particles. 2, goods packaging: goods into the clean room must be in the clean packaging containers for transport to reduce the impact of pollutants on the clean room

3.the goods circulation pipeline: set up a special clean room and stay time restrictions on personnel to reduce the factors that may cause environmental pollution.

Goods circulation pipeline: set up a special goods in and out of the channel, to avoid the goods and personnel circulation cross, to reduce the possibility of cross-contamination.
4、Goods tracking management: Establish a tracking management system for goods entering and leaving the cleanroom, including records of the source of goods, handling processes and use of goods to ensure that the inventory and circulation of goods will not pollute the cleanroom environment.
The above control measures can effectively manage the movement of people and goods in the cleanroom, maintain the cleanliness and stability of the cleanroom environment, and provide a high-quality production environment for the cleanroom application industry.
