Several aspects that need attention:
1. Whether the equipment in contact belongs to high radiation.
2. Whether toxic and harmful substances, such as volatile cleaning agents, are used in the production process. If so, an exhaust device must be installed to discharge harmful gases outdoors.
3. Whether the clean room is used as required. The clean room environment is closed, and the comfort of personnel is ensured by quantitatively supplementing fresh air. Because fresh air is quantitative, the number of people in the clean room is also strictly limited. If this limit is exceeded, the internal personnel will be deprived of oxygen, which will cause certain harm for a long time.
