Personal protective equipment (PPE) is essential for anyone working with hazardous materials, protecting people from chemicals, airborne particles, heat, toxic materials, and other potential dangers in critical or controlled environments. People working in cleanrooms are a prime example of professionals who require PPE on a daily basis.
The Role of PPE in Cleanrooms
Cleanrooms are highly controlled environments designed to maintain strict regulatory standards for airflow, humidity, and temperature. These stringent controls help maintain extremely low levels of particulate matter, ensuring that the products manufactured inside meet rigorous safety and quality standards.
A crucial aspect of ensuring minimal contaminants in cleanrooms is PPE. Those who work inside cleanrooms need proper protection against contamination, hazards, and injuries. The level of protection varies based on the cGMP, USP, or ISO classification of the cleanroom.
Proper PPE also helps maintain the controlled environment of a cleanroom by preventing outside contaminants from entering the cleanroom. With the number one source of cleanroom contamination being human skin cells, PPE not only protects the operator from external hazards, but it also protects the product being manufactured from the operator. This ultimately leads to the production of safe, high-quality products.
cGMP & ISO Classifications Mandating PPE
The current international standard for cleanrooms, ISO 14664, details specifications for every aspect of all 10 classifications of cleanrooms, including the appropriate cleanroom clothing. Along with Current Good Manufacturing Practice (cGMP), cleanroom clothing requirements are clearly outlined. For example, the most stringent cleanroom, ISO Class 1, mandates the most PPE, including coveralls (with an intersuit underneath), gloves, facemask, goggles, boot covers, bouffant hat, and hood.
As the needs of the cleanrooms change, so does the mandated PPE. Class 5, for example, doesn’t require as much as Class 1, but still requires coveralls, facemasks, gloves, shoe/boot covers, hairnets, and beard covers. Class 6 no longer requires a face mask, with Class 7 dropping coveralls for lab coats. Class 8 cleanrooms require hair and beard covers and lab coats.
Required PPE to Don in Cleanrooms
While certain pieces of PPE are required by cGMP and ISO, there are also some best practices we like to follow based on experience. It’s especially important to choose the right material and items for your specific cleanroom and applications. Explore our guide on which cleanroom garments to select for your operations, which includes a chart detailing what specific types of PPE we recommend in cleanrooms Class 5-8.
One thing we always emphasize: PPE needs to fit. Proper-fitting PPE is crucial to guarantee people the full protection needed. Plus, comfortable fits reduce distractions and allow for better focus and, thus, potentially fewer errors.
Gowning should be done outside the cleanroom or in an anteroom, and PPE should be changed prior to any time a person enters or re-enters the cleanroom. For more detailed information, take a deeper look at proper cleanroom gowning procedures.
PPE’s Impact on Product Quality and Compliance
PPE is primarily designed to protect the people working in cleanrooms (it’s in the name, after all). In addition, proper PPE worn by everyone in the cleanroom helps ensure OSHA and ANSI regulatory compliance.
Beyond that, though, proper PPE apparel and processes improve the quality of the products being made in the cleanrooms. Appropriate PPE, put on in a separate area, means workers will not introduce any contaminants into the cleanroom upon entry. This keeps the environment controlled and allows for optimal product output.
Further, the higher the quality and the more efficient the process, the less downtime, the fewer defects, the healthier the bottom line. In short, there are many connected benefits to PPE.
