A cleanroom or cleanroom is a facility ordinarily utilized as a part of specialized industrial production or scientific research, including the manufacture of pharmaceutical items and microprocessors. Cleanrooms depend on precisely controlled environmental conditions. To minimize contamination risks and protect people and assets, their technological infrastructure must adhere to the most stringent quality standards. Cleanrooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporized particles. Cleanrooms typically have a cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure. The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger in measurement, equivalent to an ISO 9 cleanroom, while by comparison an ISO 1 cleanroom permits no particles in that size range and just 12 particles for each cubic meter of 0.3 μm and smaller. The air entering a cleanroom from outside is filtered to exclude dust, and the air inside is constantly recirculated through high-efficiency particulate air (HEPA) and/or ultra-low particulate air (ULPA) filters to remove internally generated contaminants.Staff enter and leave through airlocks (sometimes including an air shower stage), and wear protective clothing such as hoods, face masks, gloves, boots, and coveralls. This is to minimize the carrying of particulate by the person moving into the cleanroom. Equipment inside the cleanroom is designed to generate minimal air contamination. Only special mops and buckets are used. Cleanroom furniture is designed to produce a minimum of particles and is easy to clean. The selection of material for the construction of the cleanroom should not generate any particle hence monolithic epoxy or polyurethane floor coating is preferred. Buffed Stainless steel or Powder-coated MS sandwich partition panels & ceiling panel are used. Corners like the wall to wall, wall to floor, wall to ceiling are avoided by providing covered surface and all joints need to sealed with epoxy sealant to avoid any deposition or generation of particles at the joints.
