Cleanrooms have extremely high environmental requirements. Maintaining cleanliness within these spaces is paramount, and identifying sources of contamination is a crucial task. In fact, some sources of contamination in cleanrooms come from workers. What’s going on? Why do workers become a source of contamination? Today, the editors of Shenzhen Fujitsu Ventilation and Purification Equipment will share their insights.
In our daily lives, the human body constantly emits various dust particles. These include shed skin cells and pathogens in sneezes. These pollutants can easily affect the hygiene of cleanrooms. So, what precautions should workers take when working in cleanrooms? Specific precautions are as follows:
1. Before entering the cleanroom, you should first use an air shower. While working, all hair, including beards, should be fully covered with hair guards to prevent falling hair from affecting product production.
2. During work, workers should minimize or minimize contact with equipment and products. If possible, fully automated production processes are preferred. If contact is unavoidable, wash your hands first and wear gloves to prevent contamination of equipment and products.
3. Numerous viruses, bacteria, and particulate matter can reside in the mouth and nose. Therefore, shouting or talking loudly should be avoided in the cleanroom. Coughing and sneezing should also be avoided. If unavoidable, do so away from the work area to avoid disrupting production.
4. In addition to taking regular baths or showers, workers should also wash their hair regularly. Maintain body cleanliness and minimize the amount of dead skin. Before entering the cleanroom, thoroughly clean your hands. Hands that appear clean can actually be a major source of contamination, transferring contaminants from one area to another. When cleaning, pay special attention to the fingernails, the base of the nails, and any injuries on the hands.
5. Personnel working in highly clean areas should maintain good health. Avoid introducing viruses into the cleanroom and damaging the environment.
