The precautions for using clean and sterile clothing involve multiple key steps that must be strictly followed to maintain a clean environment:
1. Personal preparation: Thoroughly wash and disinfect hands (at least 20 seconds) before entering the clean area, remove facial makeup, jewelry (such as watches and rings), trim nails, and avoid carrying personal belongings; When necessary, take a bath to remove oil and dirt, reducing the risk of microbial contamination.
2. Dress code:
Before wearing, check that the clean clothing packaging is intact, ensuring that the hat completely covers the hair, the mask fits tightly to the mouth and nose (pinch the nose clip), the gloves are not damaged and cover the cuffs, and the zipper or button needs to be tightly closed.
Avoid bare hands contact with the sterile surface of clean clothing. When wearing, unfold from the inside out and move gently to prevent contamination; The jumpsuit should ensure that the foot covers and hood are seamlessly wrapped, and the skin is not exposed.
3. Management during operation:
Do not wear makeup or accessories, and try to avoid direct contact with non sterile surfaces such as door handles with your hands (use body parts instead); Gloves need to be disinfected or replaced regularly.
Replace the clean clothes immediately if they are found to be damaged, contaminated, or damp; Avoid loud noises and coughing in the clean area to reduce the spread of dust particles.
4. Requirements for replacement and cleaning:
Determine the replacement frequency based on the cleanliness level (such as A/B level) (such as replacement per shift or upon entry), and regularly verify feasibility; After use, a specialized cleaning procedure (neutral detergent, avoid bleach) is required, and it should be dried in a cool place to maintain anti-static function.
5. Storage and environmental control: Clean clothes should be folded and stored to prevent contact with the ground, and a separate laundry room should be set up; Keep the operating area spacious and dry, and stop cleaning half an hour in advance.
