Advanced Containment Systems: The Critical Barrier in Cleanroom Engineering

Containment systems form the operational backbone of pharmaceutical and biomedical cleanrooms, creating physical barriers that prevent cross-contamination during high-risk processes. These engineered solutions protect both products from environmental contaminants and personnel from hazardous substances, complying with ISO 14644 and EU GMP Annex 1 requirements. Modern systems integrate mechanical, Electronic, and procedural controls to achieve <0.1% containment breach rates in critical applications like cytotoxic drug handling and pathogen research.

How Do Containment Systems Maintain Critical Barriers?

• Pressure Cascade Engineering

  differential pressure gradients (10-15 Pa steps) create directional airflow using Magnehelic gauges with 0.1 Pa resolution. In vaccine facilities, pressure cascades ensure Grade B to D zoning compliance, with automated dampers adjusting airflow to maintain containment during door openings. Pressure mapping studies validate uniformity per ISO 14644-3:2019 with ≤5% deviation across critical zones.

• Material Transfer Technology

  Closed-system transfer devices (CSTDs) utilize double-membrane RTPs validated for 10^-6 integrity failure probability. For high-potency APIs, containment solutions employ split valve technology allowing liquid transfer with <0.01μg/m³ exposure levels. VHP (Vaporized Hydrogen Peroxide) decontamination cycles between transfers ensure 6-log reduction of bioindicators.

• 1. Containment Hierarchy Implementation: Primary (gloveboxes), Secondary (BSCs), and Tertiary (room pressure) barriers
• 2. Continuous Performance monitoring: Real-time particle counters and pressure sensors with 21 CFR Part 11 compliance
• 3. Personnel Protection Integration: Air showers and emergency purge systems activated at OEL breaches
