Design Considerations and Operation:
Other sources of internal contamination are generated
through the activity of manufacturing equipment.
Although airflow design is critical, it alone does not
guarantee that cleanroom conditions will be met.
Construction finishes, personnel and garments,
materials and equipment, and building entrances and
exits are other sources of particulate contamination that
must also be controlled. Room construction and
material finishes are an important part of cleanroom
design. Room construction is important to provide an
enclosure that will house a process to exclude outside
contaminants and that the material finishes will not
contribute to particle generation in the space.
