1. Zoned Layout
Gowning rooms are typically divided into distinct zones to control contamination
-
Pre-Gowning Area: Personnel remove personal items and perform initial hand hygiene.
-
Gowning Area: Individuals don cleanroom attire, such as coveralls, gloves, and masks.
-
Transition Area: Final checks are made before entering the cleanroom.
Color-coded zones (e.g., grey, blue, white) may be used to indicate different levels of cleanliness and required attire .
2. Air Quality and Pressure Control
Gowning rooms maintain air quality standards, often classified as ISO 7 or ISO 8, depending on the adjacent cleanroom's classification. They utilize HEPA filtration systems to remove particulates and maintain positive air pressure to prevent ingress of contaminants .
3. Materials and Furnishings
Surfaces and furnishings in gowning rooms are designed for easy cleaning and minimal particle generation. Common materials include stainless steel for benches and storage units. Features like hands-free sinks, gowning benches, and storage for garments and supplies are standard .
4. Standard Operating Procedures (SOPs)
Clear SOPs guide personnel through the gowning process, emphasizing steps like:
-
Starting gowning from the top (e.g., hair cover) and moving downward.
-
Avoiding unnecessary movements to reduce particle dispersion.
-
Proper donning and doffing techniques to prevent contamination .
