[tips] management of dust-free workshop overalls

In addition to the clothes themselves, dust-free workshop uniforms can not only be a source of dust, but also have the effect of preventing dust from being emitted by the human body. At the same time, they should have basic safety, comfort, convenience, and aesthetics as materials for clothing and design. Performance, otherwise due to different styles of clothes, fabrics and underwear, directly affect the clean city of the number of dust and colonies.

First, uniforms for general production areas, control areas, and clean areas should be clearly distinguished in style and color and must not be mixed.

Second, the uniforms of the general production area are washed once or twice a week. The uniforms in the control area and the clean area must be cleaned and disinfected in every shift.

Third, when the work is over, the staff in the control area and the clean area shall promptly change their work clothes and put them into the disinfected window to be washed by special personnel. Do not bring out the control area or the clean area.

Fourth, washing and drying of work clothes should be performed in a clean room to avoid dust and insect contamination. Work clothes of different cleanliness requirements should be washed separately. After the sterile clothes in the clean area and the control area are washed and dried, they are loaded into the sterilization bags one by one, and are sterilized. After the sterilization, make a state mark and indicate the sterilization date. Use the sterile work clothes within 2 days.

Fifth, the working clothes cabinets should be divided into working clothes for changing clothes and changing clothes for clothes, and they should be clearly marked. They must not be mixed to prevent cross-contamination.

Sixth, the underwear fabrics worn by the operators are preferably polyester. Although they wear clean work clothes on the outside, they can still emit dust. Some foreign countries have done tests. Different underwears have different amounts of dust. Polyesters are the least, followed by cottons, and sweaters are the most common.

The dust-free workshop is designed to control planktonic microorganisms and dust in space. The management of operators and their clothing is closely related to dust and microbial contamination in cleanrooms and must be highly valued.
