The one-piece clean suit is a key barrier to maintaining a high cleanliness environment, and its use must strictly follow regulations, with the core being to prevent contamination and ensure sealing. The following are key precautions:
1. Preparation before wearing: Before entering the changing area, hands must be thoroughly cleaned and disinfected to ensure that hair is completely wrapped in the hat and to avoid any cosmetics or accessories. Clean clothes should be stored in designated areas and checked for damage or contamination before wearing.
2. Wearing process: It is necessary to wear in the correct order: first wear the jumpsuit, then wear the hood and mask, and finally wear the shoe cover and gloves, ensuring that the gloves completely cover the cuffs. When wearing a jumpsuit, the movement should be slow to avoid air turbulence. After inserting the arm, ensure that the cuff is tightly connected to the glove to prevent the forearm skin from being exposed and becoming a source of pollution. When operating the zipper, avoid touching the zipper teeth and outer surface with your fingers to ensure that the placket is completely closed.
3. After wearing, it is prohibited to run, make noise, or carry personal belongings in the clean area. Avoid leaning against equipment or walls, reduce unnecessary movements, and prevent particles from being generated by friction of clean clothing. If the clean clothes are found to be damaged or contaminated, they should be replaced immediately.
4. Maintenance and storage: Clean clothes need to be cleaned regularly, with the frequency depending on the cleanliness requirements of the workshop, usually 1-2 times a week. Cleaning should be carried out in an environment not lower than ISO8 level, using filtered water. After work, clean clothes should be stored in a clean, independently numbered wardrobe to avoid cross contamination.
