Cleanroom Protocols and Procedures
Cleanroom Zones and Attire
- The cleanroom changing areas are divided into three zones: the black zone for unauthorized items, the gray zone for handwashing and dressing, and the white zone for final preparations.
- Newcomers must remove bulky rings to prevent skin flakes from contaminating the environment and to avoid damaging protective gloves.
- Valuable items should be stored in a closed drawer; however, wearing watches or small items in inner pockets may be permitted depending on cleanroom classification.
Hand Hygiene Practices
- In pharmaceutical or microelectronics manufacturing, thorough washing of hands and arms up to the elbows is crucial. Training should emphasize proper handwashing techniques to minimize germ exposure.
- The importance of rubbing palms and fingertips during washing is highlighted as it can disrupt skin flakes that harbor germs.
Headgear Requirements
- Wearing a cap under a gown or hat is essential for contamination control in high-class cleanrooms; all hair must be completely covered regardless of headwear type.
- Properly fitting headgear is necessary to ensure complete coverage of hair, which helps maintain cleanliness standards within the cleanroom environment.
Gowning Procedures
- When donning gowns, they should fit snugly without being overly tight; adjustable gowns provide comfort while ensuring effective contamination control through mechanical extraction systems like Dryden Maximum filters.
- Gowns must fall loosely over pants or blouses designed as two-piece suits for cleanrooms; specific order of dressing (pants first) is recommended for optimal protection against contamination.
Footwear and Glove Usage
- It’s advised not to wear gowns outside designated areas due to potential contamination risks; shoe covers are typically used at entry points with mats placed in white zones to eliminate particles from footwear soles.
- Gloves are mandatory protective gear; instructors demonstrate correct glove application techniques, especially in healthcare settings where sterilized gloves may be required as part of training protocols.
- In some cases, double-gloving is practiced to mitigate contamination risks if one pair becomes compromised during operations within the cleanroom environment.
