Understand the classification of pollution sources in clean rooms

A clean room is a well sealed space where air cleanliness, temperature, humidity, pressure, noise, and other parameters are controlled as needed.
Deeply understand the classification of pollution sources in cleanrooms:
Source 1 of Pollution in Cleanrooms: Equipment Pollution
Equipment such as paint, coatings, building materials, and air conditioning system debris in clean rooms can cause pollution to the clean space.
Source 2 of Pollution in Cleanrooms: Personnel Pollution
In the clean room, the dander and oil produced by the staff's skin, cosmetics and perfume, saliva, clothing debris (cotton wool, fiber, etc.) and hair may cause pollution in the clean space.
Pollution source three of cleanroom: tool contamination
Dust particles generated during friction or packaging between tools, as well as cleaning supplies such as brooms, mops, and dust collectors, can also cause contamination of clean spaces.
Source 4 of Pollution in Cleanrooms: Fluid Pollution
Floating objects in the air, organic matter, and water vapor; Floor polishing agents and coatings; Chemical cleaning drugs, plasticizers, deionized water and other fluid substances can cause pollution in clean spaces.
The above four points are a rough classification of clean room pollution sources, which need to be considered from multiple aspects in the daily maintenance and use of clean rooms. Only through the application of technological means, personnel management, and equipment condition detection can a clean room be maintained and the effectiveness of clean room use be improved.
