How to Validate a Containment System
Containment system validation — definition: A structured qualification process (IQ/OQ/PQ per GAMP 5) that proves a containment system — isolator, endless liner, split-butterfly transfer — consistently achieves the required OEB airborne limit: OEB 4 ≤1 µg/m³, OEB 5 ≤0.1 µg/m³ or ≤1 ng/m³. SMEPAC (2009/2023 rev.) is the industry standard test protocol for powder containment equipment, validated by surrogate compound (lactose/naproxen) air sampling.
Key steps to validate a containment system
- Standards: SMEPAC 2023, GAMP 5, ISO 10648-2 (isolators), GMP Annex 1 (2022), 21 CFR Part 211, ISPE Containment Manual
- Test phases: IQ (installation verification) → OQ (operational limits) → PQ (process performance, SMEPAC surrogate)
- OEB benchmarks: OEB 1–2 ≤1 mg/m³, OEB 3 ≤0.1 mg/m³, OEB 4 ≤1 µg/m³, OEB 5 ≤0.1 µg/m³ (HPAPI)
- HECHT products validated: LBK-EC (OEB 4–5), endless liner SBK, glove-box isolator, ProClean Conveyor (PCC), LAS-EC drum discharger
- Documentation: SMEPAC test report, risk assessment (ICH Q9), change control (GMP Annex 15), 21 CFR Part 11 audit trail
Proper containment validation protects operators, ensures regulatory compliance and reduces recall risk. Explore HECHT's containment equipment portfolio and pharma solutions, or conduct a SMEPAC validation run at our Test & Trial Centre Delft.

Veelgestelde vragen (FAQ)
Why is design analysis important in validation?
Design analysis ensures that the containment system meets the required standards and specifications for effective operation.
What role does certification play in validation?
Certification confirms that the containment system has successfully passed all validation tests and is safe for use.
How do performance tests contribute to validation?
Performance tests assess the functionality and efficiency of the containment system to guarantee optimal performance.
What are the essential documents for validation?
Essential documents include test reports, validation summaries, and compliance certificates outlining the validation process and results.
How to address deviations during validation?
Deviations during validation should be documented, investigated, and resolved following standard operating procedures to maintain validation integrity.

FAQ — Containment system validation
What is the SMEPAC protocol and why is it the standard for containment validation?
SMEPAC (Standardised Measurement of Equipment Particulate Airborne Concentration) uses a surrogate compound (typically lactose or naproxen) at defined process conditions to measure airborne exposure in µg/m³ or ng/m³. Published by ISPE/STTI and revised in 2023, it is accepted by FDA, EMA and MHRA as evidence of OEB 4–5 containment performance. HECHT provides SMEPAC test reports for all containment equipment (LBK-EC, SBK liner, isolators).
How many validation runs are required for a containment system under GMP?
GMP Annex 15 and 21 CFR Part 211.68 require a minimum of three consecutive successful PQ runs at worst-case operating conditions (maximum batch size, highest OEB compound). Each run must meet the OEB airborne limit with a safety factor of ≥3×. HECHT's Test & Trial Centre in Delft can host full SMEPAC PQ campaigns with customer compounds (real or surrogate) under GMP-like conditions.
What documentation is needed after containment system validation?
A complete validation package includes: URS, DQ, IQ, OQ, PQ protocols and reports; SMEPAC air sampling data; risk assessment (ICH Q9 FMEA); cleaning validation (MACO, ATP, TOC); and a Validation Summary Report (VSR) signed by QA. Change control (GMP Annex 15) governs any post-validation modifications. HECHT supplies a pre-populated validation master plan template with all equipment documentation.
