gowning room

Gowning rooms are transitional spaces where workers change into cleanroom garments before entering the fab, preventing contamination. **Design**: Progressive cleanliness - street clothes area, partial gowning, final gowning in increasing cleanliness. Air locks between zones. **Gowning sequence**: Shoe covers, hair cover, first smock, then full cleanroom suit (bunny suit), gloves, face mask, boot covers, goggles. Order matters. **Pressure cascade**: Gowning room at intermediate pressure between outside and cleanroom. Airflow always toward dirtier areas. **Benches and seats**: For sitting while changing shoe covers. Designed for easy cleaning. **Mirrors**: To check gown integrity before entering. **Training**: Workers trained on proper gowning procedure. Improper gowning is contamination source. **Degowning area**: Separate area for removing garments when exiting. Separates dirty and clean sides. **Air showers**: Some fabs include air showers to remove particles before entering. **Traffic management**: Limit number of people gowning simultaneously. Scheduling for shifts.
