Human as a particle source in cleanroom

Managing production cleanliness based on life cycle approach has a growing importance in cleanrooms. Production cleanliness includes requirements for facilities, humans, material flows and production. In cleanrooms it is essential to pay attention to reliable documentations and appropriate materials and garments. Present standards don't give a simple way to analyze e.g. the garment's cleanroom properties and suitability to cleanroom. A human is a significant particle source in cleanrooms. A cleanroom garment is one of the best available techniques to manage emitted particles from a human. Cleanroom garments can e.g. protect the worker from particles released from production or product from particles released from the worker. It is essential to find a proper way to manage released particles. There are many ways to evaluate risks and suitability of materials and garments for cleanrooms. It should be paid attention to what kind of materials are used in the garment, how functional barrier is the whole garment-human system and what kind of effect has cleanroom materials and garments on the production cleanliness.
