Handling deviations and Out Of Specification (OOS) results in glove manufacturing is paramount for maintaining GMP compliance and product safety. A deviation is any unplanned variation from approved procedures, while an OOS result indicates a test result falling outside pre-defined acceptance criteria. Both require immediate investigation and corrective actions.
Our process begins with immediate containment – preventing further production using the affected batch. We then conduct a thorough investigation, including reviewing manufacturing records, equipment logs, and operator training records. Root cause analysis, using tools like Fishbone diagrams or 5 Whys, helps pinpoint the underlying problem. A deviation report is meticulously documented, outlining the deviation, investigation, root cause, corrective actions (CAPA), preventative actions (PA), and verification of effectiveness. For OOS results, we repeat testing, possibly using different methods and equipment. If the OOS persists, we thoroughly investigate the testing process itself, looking for errors in sampling, equipment calibration, or operator technique. Retesting may be conducted on retained samples. Depending on the severity, the batch may be rejected, reprocessed (if feasible), or quarantined pending further investigation. Complete documentation is critical for traceability and regulatory compliance.
For example, imagine an OOS result for tensile strength. We’d first re-test. If the OOS is confirmed, we’d investigate the batch’s processing parameters, checking for inconsistencies in the latex formulation, curing process, or equipment settings. We’d trace back to the raw materials and look for variations in supplier quality. The investigation, corrective, and preventative actions would all be documented and reviewed by quality control and management.
