Understanding Cleanroom Classifications
To master cleanroom protocol, you need to grasp the intricacies of cleanroom classifications. These guidelines ensure that your controlled environment meets the necessary requirements for your specific industry and processes.
ISO 14644-1 standards
The International Organization for Standardization (ISO) 14644-1 standard is the primary authority for cleanroom classification in the US and Canada. This system includes nine classes, ranging from ISO 1 (the cleanest) to ISO 9 (the least clean). The classification is based on the number and size of particles per cubic meter of air.
For example, in an ISO 7 cleanroom, the concentration of particles ≥0.5 µm should be below 352,000, while particles ≥5 µm should be 2,930 or lower. To achieve and maintain these cleanliness levels, cleanrooms use HEPA filters and specific airflow principles.
The number of air changes per hour is a crucial factor in maintaining cleanliness. For instance, an ISO 5 cleanroom requires 240-600 air changes per hour, while an ISO 7 cleanroom needs 60-150 air changes per hour.
Importance of classification for maintenance
Understanding cleanroom classifications is vital for effective maintenance and contamination control. Each class has specific requirements for air quality, documentation, and cleaning procedures. Compliance with these standards is an ongoing process that begins with facility design and continues throughout its operational lifecycle.
Key aspects of regulatory compliance include:
- Developing a comprehensive User Requirement Specification (URS) for cleanroom construction
- Implementing a qualification program that runs parallel to the construction timeframe
- Selecting appropriate construction materials compatible with cleaning and disinfection programs

Daily surface and equipment cleaning
Daily cleaning is vital to prevent the buildup of particles and microbes. Start by removing loose debris using disposable wipes or pre-saturated cloths. This pre-cleaning stage prepares surfaces for more thorough cleaning. Next, use a detergent solution to eliminate remaining substances and dirt. Always work from the cleanest areas towards dirtier ones, moving from top to bottom to minimize further contamination.
After cleaning, rinse surfaces with clean, deionized water or use presaturated IPA wipes to remove any residue. This step is crucial for maintaining the integrity of your cleanroom environment. Finally, allow surfaces to air dry or use single-use drying cloths to prevent bacterial growth and cross-contamination.
Proper mopping techniques
Mopping plays a critical role in cleanroom maintenance. Use specialized cleanroom mops made from materials like microfiber or non-woven polyester, which generate minimal particles and effectively capture contaminants. When mopping, follow a specific pattern to ensure complete coverage. Use an S-shaped pattern and avoid going over the same area twice to prevent recontamination.
For optimal results, implement a multi-bucket system. Use one bucket for the cleaning solution, another for rinsing the mop, and a third for wringing out dirty water. This approach helps maintain the cleanliness of your mopping solution throughout the cleaning process.
Specialized cleaning agents
Choosing the right cleaning agents is crucial for effective cleanroom maintenance. Opt for EPA-approved products specifically designed for cleanroom use. These agents should be low in residue and free from contaminants that could compromise the cleanroom’s integrity.
Consider using green cleaners made from biodegradable, non-toxic, and renewable resources. These environmentally friendly options are just as effective at removing contaminants while promoting sustainability and health safety. When using any cleaning agent, follow proper dilution techniques and adhere to the manufacturer’s instructions for optimal results.
