About This Checklist
The ISO 14644 Cleanroom Pressure Cascade System Audit Checklist is a vital tool for ensuring the integrity of pressure differentials in pharmaceutical cleanroom environments. This comprehensive checklist aligns with ISO 14644 standards, focusing on the evaluation, maintenance, and monitoring of pressure cascade systems that prevent contamination between cleanroom areas of different classifications. By systematically auditing pressure cascade systems, pharmaceutical companies can enhance contamination control, maintain proper air cleanliness levels, and ensure compliance with regulatory requirements. Regular implementation of this checklist supports the overall cleanroom performance, aids in identifying potential breaches in containment, and contributes to product quality assurance in pharmaceutical manufacturing.

The checklist covers pressure differential measurements, airlock functionality, door interlock systems, alarm and monitoring systems, HVAC control parameters, and documentation of pressure readings and system maintenance.
A properly maintained pressure cascade system ensures that air flows from areas of higher cleanliness to areas of lower cleanliness, preventing the ingress of contaminants and maintaining the required cleanliness levels in critical areas.
The audit should involve cleanroom engineers, HVAC specialists, quality assurance personnel, facilities managers, and contamination control experts to ensure a comprehensive evaluation of the pressure cascade system.
Comprehensive audits should be conducted quarterly, with continuous monitoring of pressure differentials. More frequent checks may be necessary for critical manufacturing areas or following any changes to the HVAC system.
Identified deficiencies should trigger immediate corrective actions, such as recalibration of pressure sensors, adjustment of HVAC settings, or repair of door seals. A follow-up audit should be scheduled to verify the effectiveness of these actions and ensure system stability.
