How To Select The Right Apparel For Your Cleanroom Classification

    Cleanroom garments include boots, shoes, aprons, beard covers, bouffant caps, coveralls, face masks, frocks/lab coats, gowns, glove and finger cots, hairnets, hoods, sleeves and shoe covers. The type of cleanroom garments used should reflect the cleanroom and product specifications. Low-level cleanrooms may only require special shoes having completely smooth soles that do not track in dust or dirt.

    Today, the cleanroom plays a vital role in manufacturing processes in the pharmaceutical and microprocessor industries, as well as other sectors where it is imperative to control airborne contaminants. It’s likely that cleanrooms will undergo further developments as the trend toward miniaturization in manufacturing makes sensitive materials increasingly vulnerable to the negative effects of contamination. A cleanroom classified as ISO Class 5 or ISO Class 6 requires cleanroom coveralls, along with hoods, gloves, and booties . For sterile processing, additional precaution is needed to assure that no sterile surfaces contact non-sterile surfaces during gowning, processing, or cleaning.

    The impact of particles on a production process is not always predicated by volume, but instead by specific sizes of problematic particles based on the application. The increased specificity of ISO class cleanroom standards provides a more accurate and translatable picture of cleanliness, because it defines allowable particle counts in stages of 0.1 micron – 5 microns. The 0.5 micron standard of the FS 209E systems is continually growing outdated; as the rush for smaller components and more sensitive devices grows and cleanrooms become cleaner, particle thresholds require increased sensitivity. Continuous improvement can come from better control or elimination of variability in attributes that impact barrier performance.

    One must consider any other ways that sterile clothing may interact with a specific process or application. The class of the cleanroom is one of the important factors that must be considered when choosing the garment for the cleanroom. Those cleanrooms that are of higher cleanliness always require a garment that covers the entire body to minimize the chances of contamination in the cleanroom. For example, employees working in the ISO class 5 cleanrooms need to wear not only the coveralls but also hoods and boots as well as masks and gloves. Cleanroom design and construction requires tight controls over contamination, air flow rate, pressure, temperature, and humidity.

    With regards to the ease of the gowning process, it’s worth considering design features, such as those that prevent clothing from touching the floor or from being touched on the outside during gowning. The choice of material can play a part in ease of use; for instance, gloves made of more elastic materials are easier to put on and double don. Integrated clothing, such as clothing that features an integrated hood and mask, can also make the gowning process simpler and easier. Don’t let anyone enter the cleanroom if they aren’t appropriately covered, with clean and gloved hands, face masks, covered shoes, safety glasses, etc. Please explore our website to view the high-quality ESD cleanroom garments available from Prudential Cleanroom Services, an industry leader in uniform laundry services since our founding in 1960. This quality is especially important in the more strict ISO classes, where technicians generally must wear full-body uniforms.

    The requirements for disposal and use ofgowns and garmentsdiffers upon cleanroom classification and application. The cleanest cleanrooms dispose of garments after each exit and entry, while cleanrooms with the highest particle thresholds may only change garments twice a week.

This informational guide shouldnever take precedenceover consulting with acleanroom engineering consultantwho is familiar with your specific equipment and classification needs.

    There are other factors to keep in mind that may depend on the industry or type of cleanroom. For example, clothing that has lower potential to generate static electricity is important in cleanrooms producing semiconductors. There is also the question of how often clothing must be changed, and if reusable or disposable garments are more suitable from both a cost and cleanliness perspective. Sterile clothing made at manufacturing sites which are compliant with FDA CFR 21 part 820, ISO13485 certified and/or ISO9001 certified may be easier to integrate in terms of quality systems requirements. Quality control documentation form the sterile manufacturer can also help, for example certificates of conformance to specification, certificates of irradiation, periodic sterile validation audits and lot testing of performance characteristics. Because sterile clothing is an integral part of sterile manufacturing process equipment, any modifications to sterile clothing that could impact the output quality of this process.

    There are many stakeholders in the sterile garment selection process, for example Finished Product Quality control, Environmental Quality control, Production Management, Health and Safety, Procurement and Waste Disposal. The manufacturer of the sterile clothing can support all decision makers involved in the selection process. Static electricity is a serious contamination threat in cleanrooms, especially ones that specialize in the manufacture or handling of sensitive equipment or substances. What this means for you, as someone involved in the management of controlled environments, is that you need to remain up to date on evolving standards in cleanroom processes. That includes understanding the huge importance of cleanroom attire for keeping these environments safe and operating effectively.

    This guide provides a framework for cleanroom management, protocol standards, specifications, and processes for general manufacturing and biomedical applications. Because each cleanroom class can require slightly different supplies and protocol, this overview connects best practices with application specific techniques for gowning, wipedown, and particle control. This guide should serve as a resource for understanding broad-line cleanroom consumable needs, but not as a replacement for expertise tailored to your application. Typically used in manufacturing or scientific research, a cleanroom is a controlled environment that has a low level of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. To be exact, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. The ambient air outside in a typical city environment contains 35,000,000 particles per cubic meter, 0.5 micron and larger in diameter, corresponding to an ISO 9 cleanroom which is at the lowest level of cleanroom standards.
