Cleanroom Compliance
One final item to discuss is the periodic tasks for demonstrating continued compliance of a cleanroom with ISO 14644 standards. These tasks include the following:
Common Contaminants
Once a cleanroom is built and activated, constant monitoring and maintenance are required. Equipment, tools, furniture, raw materials, outside air, people and even the type of garment worn by them will have to be examined for contamination risk before being allowed to enter. Specific conductivity material, antistatic characteristics, out gassing properties or even antimicrobial aspects may be required.
Entrance, Garment & Ante-rooms
A mistake often encountered in present day cleanroom facilities is the assumption that the garmenting area is not part of the cleanroom. This area is the transition point from the “dirty” to “clean”, which means the section leading into the cleanroom should be at least as clean as the cleanrooom itself.
Hand Hygiene
To understand different approaches for hand cleansing understanding of normal bacterial skin flora is essential. Normal human skin is colonized with bacteria. Different parts of the bodies have varied bacterial counts. In 1938 bacteria recovered from hands were divided into two categories, Transient and Resident.
Do’s & Don’ts of Glove Use
Grasp one of the gloves and cuff and pull it partway off. The glove will turn inside out. It is important to keep the first glove partially on your hand before removing the second glove.
Gowning Protocol
Garment should produce little or no particulate emission. This requires the fabric or material to be stable, possessing a high ability to resist breakdown.
