Verifying Particle Count and Airflow in Cleanrooms
Verifying particle count and airflow in cleanrooms is essential to confirm the environment meets design expectations and safety criteria. You’ll track particulate load at critical locations using calibrated counters, ensuring measurements align with the facility’s cleanroom classification. Maintain a documented sampling plan, including times, ports, and potentially varying loads, so results are defensible under audits. You should also monitor airflow patterns with smoke tests or anemometers to verify uniform delivery and exhaust removal. Prioritize direct, actionable readings over estimates; report any deviations promptly and identify corrective actions. Keep equipment calibrated and protected from contamination during testing to preserve data integrity. Finally, compare results to design specs, implementing containment https://passbox-airlock.huicopper.com/3-tips-for-finding-budget-friendly-air-filtration-providers controls if you observe persistent nonconformance, then re-validate after adjustments.
