Introduction A high-performance cleanroom is not a “set it and forget it” asset. To maintain the integrity of your pharmaceutical or semiconductor production, a rigorous cleanroom maintenance checklist is essential. Neglecting routine care can lead to particulate spikes, failed audits, and catastrophic downtime. At Dersion, we believe that the construction of a facility is just the beginning; sustaining its performance is where true quality lies.
Routine monitoring is the first line of defense. Automated sensors should track parameters 24/7, but manual verification is still a cornerstone of GMP Compliance.
- Pressure Differentials: Ensure the 10-15 Pa cascade is maintained between zones.
- Temperature & Humidity: Calibrate sensors quarterly to prevent drift that could impact sensitive chemical processes.
The heart of your Cleanroom HVAC design is the filtration system.
- Leak Testing: HEPA/ULPA filters should undergo aerosol challenge testing annually (or semi-annually for ISO 5 zones) to ensure no bypass leakage.
- Airflow Velocity: Measure unidirectional flow speeds to ensure contaminants are being effectively “swept” away from critical work surfaces.
Cleaning a controlled environment requires specialized chemicals and techniques.
- The Top-Down Approach: Always clean from the ceiling down to the floor, and from the cleanest area toward the exit.
- Non-Shedding Materials: Use only polyester mops and ultra-pure water (DI water) or IPA (70% Isopropyl Alcohol) to prevent adding more particulates than you remove.
Humans are the primary source of contamination. Maintenance includes auditing the behavior of the people inside.
- Gown Integrity: Inspect cleanroom suits for fiber shedding and ensure that the laundering process meets the required ISO class standards.
Conclusion Consistency is the soul of contamination control. By implementing a proactive Cleanroom maintenance program, you not only extend the life of your equipment but also guarantee the safety and reliability of your products.
