1. Purpose

To outline a comprehensive and risk-controlled procedure for cleaning of equipment, areas, and accessories following a batch failure during elixir manufacturing, ensuring complete removal of residues and preventing cross-contamination.

2. Scope

This SOP applies to all equipment, utensils, pipelines, and related surfaces used during failed or rejected batches of elixirs in the Elixir Manufacturing Department.

3. Responsibilities

  • Production Operator:
    • Perform initial segregation and cleaning activities post-failure.
  • Production Supervisor:
    • Initiate cleaning protocol and inform QA and Engineering.
  • QA Officer:
    • Verify cleaning effectiveness and approve equipment for reuse.
  • Engineering Department:
    • Support equipment disassembly and cleaning in case of residue adherence or operational issues.

4. Accountability

The Production Head is accountable for executing the cleaning process after batch failure. QA Head is responsible for verification, compliance, and documentation of the entire process.

5. Procedure

5.1 Initiation

  1. Immediately inform
QA, Engineering, and Production Head upon confirmation of batch failure.
  • Segregate the failed batch material and transfer to a designated area with “REJECTED – HOLD FOR DISPOSAL” label.
  • Quarantine the equipment used until cleaning is completed and verified.

    • 5.2 Risk Assessment

    1. QA to perform a risk assessment based on:
      • Nature of failure (e.g., microbial contamination, physical non-conformity, chemical incompatibility)
      • Solubility and stickiness of the product
      • Contamination potential
    2. Determine whether routine or intensified cleaning is required.

    5.3 Cleaning Execution

    1. Drain all process lines and rinse with purified water to remove bulk residue.
    2. Apply 1–2% validated detergent solution and manually scrub product-contact surfaces.
    3. Perform multiple rinses with purified water until rinse water meets conductivity/pH acceptance criteria.
    4. If product was alcohol-based, use appropriate solvent flush or hot water as per cleaning validation.
    5. Inspect and clean auxiliary parts like valves, nozzles, gaskets, and transfer pipes.

    5.4 Verification and Documentation

    1. QA to visually inspect for residual material, stains, or odor.
    2. If required, collect swab or rinse samples for analytical testing as per validation protocol.
    3. Document cleaning activity in the Batch Failure Cleaning Logbook (Annexure-1).
    4. Equipment to be marked as “CLEANED – READY FOR USE” only after QA approval.

    5.5 Reassembly and Clearance

    1. Engineering to support reassembly of any disassembled parts.
    2. Conduct air drying or hot air cabinet drying as per SOP/ELX/185/2025.
    3. Final clearance given by QA to Production before use in subsequent batch.
