There are three kinds of dust particles carried by the human body; One is the external environmental pollutants randomly attached to hair, clothes and shoes; And the pollutants left on clothes and shoes. The other is personal smear, such as hair oil, perfume, eye cream, powder cake and so on. The third is the wear and tear of clothing.
Human body is one of the main sources of bacteria in clean room.
In view of the above situation, the personnel entering the clean room should take some necessary cleaning measures. People network measures include:
1) washing
Wash hands, face and even the whole body epidermis with water to remove temporary attachments and accumulated body surface secretions.
2) Change clothes and shoes
In order to reduce the pollutants brought into the clean room by the outside world, people who enter the clean room generally change their shoes and clothes. Generally speaking, the requirements for work clothes are not only high surface cleanliness, but also easy to remove pollutants, which can cover most of the human body like a filter, so that the dust bacteria emitted by the human body can be filtered on one side of the human body, and it is not easy to generate static electricity. The shoes that go out carry the most dirt, so they must be washed, vacuumed and pasted at the entrance to avoid excessive pollution in the lobby.
3) Air shower
The air shower room is a temporary attachment device that uses high-speed clean air to clean the whole body clothes and exposed surfaces. Measures such as washing, changing clothes and blowing air can reduce the external pollutants carried by human body and clothes, reduce the pollution caused by direct contact, and isolate most of the body and underwear from indoor air to some extent.
The blowing time of human body in the blowing room is related to the blowing speed. The shorter the blowing time, the higher the blowing speed. On the contrary, it can be smaller. Generally, the blowing time is between 20 and 60s.

At the entrance of a clean room with low requirements for personnel purification, sometimes an air lock is used in conjunction with an air curtain, a unit with a medium and high efficiency filter is arranged on the top plate of the entrance of the clean room, and the air flow is sprayed downward through a slit to form an air curtain for shielding pollution.
