Immediate actions taken to isolate suspect products and prevent further shipment or use of nonconforming items.
Containment action is the first response when a defect could impact customer delivery or safety.
It is temporary by design and must transition into formal CAPA when the risk and cause investigation require formal corrective action.
Typical containment methods
Teams quarantine suspect lots, tighten sorting criteria, add gate inspections, or pause shipment release.
Strong containment protects customers while root cause investigations continue.
Common failure modes
Containment fails when scope is unclear, affected serials are not traced, or communication is delayed across teams.
Use lot and serial-number traceability to locate affected units. A requirements traceability matrix serves a different purpose and cannot replace material traceability.
Key takeaways
- Containment protects customers before permanent fixes are validated.
- Speed and scope clarity determine containment effectiveness.
