The procedures and requirements for dressing in a cleanroom are very strict. Proper attire is essential to maintain the required cleanliness level and prevent contamination. 1. The dressing process should be divided into three stages: general area, clean area, and the cleanroom itself. This ensures that personnel gradually transition from a normal environment to a highly controlled one. 2. A common practice is to change shoes first, then remove outer clothing before entering the clean workshop. In some cases, individuals are not allowed to enter the clean area without proper attire. A second change may involve switching into clean shoes and wearing specialized cleanroom garments. These garments help maintain positive pressure within the cleanroom, ensuring that air flows outward rather than inward, minimizing contamination risk. While it's not necessary to send purified air constantly, it’s also not impossible to do so at a reduced rate. After dressing properly, staff can enter the cleanroom, but only if they follow the correct protocol. Color coding of uniforms helps identify different areas or levels. Anyone who doesn't follow the dressing rules may face serious consequences. 3. Entering a cleanroom (such as a 100 or 10,000 level area) typically requires a half-hour preparation period. Changing into sterile clothes is crucial. Even after changing, the number of particles on the body is significantly reduced. In a 25m² dust-free workshop, the number of airborne particles increases by only 202 per minute, which is minimal. Therefore, during night shifts, when sterile clothing is changed, it's possible to achieve a 100-level environment. According to EU GMP guidelines, equipment used in aseptic production (in the A-zone) can be located in up to C-level areas, provided that AB-level dressing is required. This aligns with the general rule in EU GMP Annex 10: "Aseptic production equipment can be installed in at most C-level areas, provided that AB-level dressing is required." This means that to enter certain 100-level zones within a 10,000-level area, you only need to follow the 100-level dressing requirements—essentially using higher-standard attire to access lower-level cleanrooms. 4. In a 100-level cleanroom, there is usually a sterile gown available at the entrance or inside the room. Staff can put it on before entering. Alternatively, they may change into sterile clothes indirectly before entering the clean area. 5. All clothing removed upon entry and the new clothes to be worn must be carefully managed. This is a critical part of the dressing procedure, including shoe changes, undressing, and putting on easy-to-wear garments.
