Dynamic pass boxes, integral to cleanroom operations, serve as auxiliary units facilitating the transfer of items between cleanrooms and non-cleanrooms. Managing dynamic pass boxes requires adherence to specific cleanliness standards, especially in correlation with the higher-level cleanroom it connects to.
To ensure efficient and contamination-controlled operations, follow these comprehensive guidelines for dynamic pass box usage:
1. Strict Separation of Items and Personnel Movement
Enforce rigorous separation of transferred items from personnel movement, maintaining a pristine working environment.

2. Stock Receiving and Transfer
- Unpack and clean exterior upon stock reception, sending it to the raw workshop.
- Utilize the dynamic pass box for transferring stock to designated areas.
3. "One Open, One Close" Rule
- Adhere strictly to the "one open, one close" rule for pass box doors during material transfer.
- Open the outside door to insert materials, close it, then open the inside door to retrieve them.

4. Transfer from Cleanroom
For materials exiting the cleanroom, pass through the airlock before proceeding to the external packaging room.
5. Semi-Product Transportation
Transport semi-products from the cleanroom through the pass box to the temporary storage room, facilitating organized workflow.
6. Handling Polluted Materials
Use the pass box for transporting highly polluted materials and wastes into the cleanroom, ensuring minimal contamination risk.
7. Post-Transfer Cleaning and Sterilization
After stock input and output, conduct thorough cleaning and sterilization of the pass box, airlock, temporary storage room, and cleanroom areas.
While these guidelines provide a foundational framework, it's essential to note that specific environments may necessitate tailored instructions. Always adhere to manufacturers' guidelines and pass box specifications to guarantee optimal functionality and adherence to industry standards.
