How to Get Clean Room Procedures Performed CorrectlyCleanrooms provide a controlled environment for sensitive scientific research and manufacturing processes to take place. They are designed in a way to minimize the introduction, generation, and retention of particles inside the room. It requires an incredible amount of technology to create and maintain such levels of cleanliness. Cleanrooms have air filtration systems that completely change the air several times per minute and reduce the chances of harmful airborne particles getting into products. Proper cleanroom gowning and cleaning procedures are needed to ensure consistent cleanliness and contamination control. While procedures vary depending on the cleanroom classification and application, there are general basics that can help in keeping the environment clean. This guide will look at the cleanroom procedures for reaching and maintaining cleanliness. Cleanroom Gowning ProcedureHuman beings are the largest sources of contaminants in cleanrooms. The body naturally hosts unwanted bacteria besides shedding the skin cells and hair and exhaling bio-organisms. This is why it’s important for cleanroom personnel to wear the required cleanroom apparel depending on the cleanroom’s classification. Gowning procedures start right at home by observing personal cleanliness such as bathing, brushing the teeth, trimming the hair, and applying non-silicone moisturizers to reduce flakes on the skin. Cleanroom personnel should keep off hair gels and sprays, aromatic aftershaves, perfumes, and certain types of body lotions as they aren’t cleanroom compatible. Employees with access to cleanrooms should also wash their hands before going in and apply cleanroom-compatible hand creams before gowning. Here’s the donning sequence for cleanroom access:
Doffing sequence: Reverse the procedure above and place all the disposable items in the trash. For aseptic pharmaceutical cleanrooms, all garments should be discarded on exit and a new set used on reentry. Reusable hoods, boots, and coveralls should be placed in the proper receptacle while goggles or eye shields placed in another. Personnel can leave the cleanroom without doffing the garments during emergency evacuations. It’s important to remember never to touch any exposed part of the body with a gloved hand. You should also never use powder gloves in a cleanroom or allow the garments to touch the floor. Cleanroom Cleaning ProcedureThe cleanliness of a cleanroom doesn’t end with the disposal of used gowns and garments upon exit. The cleanroom itself has to be cleaned. Here are the guidelines for cleanroom cleaning:
Not all cleanrooms use the procedures listed for their gowning and cleaning guidelines. As mentioned, that depends on the classification of the cleanroom and its application. This guide is only intended to give you an idea of how to keep your cleanroom from getting contaminated and help you get started. These are simple tasks but their benefits to the maintenance of cleanroom standards are significant and compounding.
