(1) Dust Generation
Due to the materials used in cleanroom-approved equipment, the amount of dust that they generate is negligible (only around 10% of total dust generation.)
Humans, on the other hand, are a major source of dust particles. Although the evolution of materials and styles of clothing are resulting in less and less dust being
produced on average, a static human being will produce as much dust as 8 m2 of flooring. The following are factors relevant to dust production:
(A) Clothing Materials: Cotton produces the most dust of any common clothing material, followed by dacron, polyester, and then nylon.
(B) Clothing Style: Looser clothing generally produces more dust.
(C) Movement: When in motion, humans produce 3-7 times more dust than when at rest.
(D) Detergent: Using detergent as opposed to regular water reduces dust generation by up to 500%
(2) Bacteria Generation
(A) Skin: Humans produce a new layer of skin about every four days. Every minute humans shed around 1,000 pieces of dead skin.
(B) Hair: Human hair is constantly falling out.
(C) Saliva: Saliva contains salt, enzymes, potassium, oxides, and food particles.
(D) A human at rest will produce at least 10,000 particles larger than 0.3µm per minute.
(E) A human whose head and torso are in motion will produce at least one million particles larger than 0.3µm per minute.
(F) A human walking at 0.9 m/s will produce at least five million particles larger than 0.3µm per minute.
