1. Purpose

This Standard Operating Procedure (SOP) establishes the guidelines for periodic cleaning and inspection of raw material storage units to ensure a clean, contamination-free, and compliant environment in accordance with Good Manufacturing Practices (GMP).

2. Scope

This SOP applies to all storage units, including shelves, racks, bins, and cabinets used for storing raw materials such as Active Pharmaceutical Ingredients (APIs), excipients, solvents, and chemicals within the warehouse.

3. Responsibilities

  • Warehouse Personnel: Perform routine cleaning and visual inspections of storage units.
  • Housekeeping Team: Conduct scheduled deep cleaning of storage areas using approved cleaning agents.
  • Warehouse Manager: Supervise cleaning activities and ensure that all inspections are documented properly.
  • Quality Assurance (QA): Verify cleaning effectiveness and approve the use of cleaned storage units.

4. Accountability

The Warehouse Manager is accountable for ensuring that all raw material storage units are cleaned and inspected periodically. The QA Manager is responsible for verifying compliance with GMP

standards.

5. Procedure

5.1 Routine Cleaning Procedures

  1. Daily Cleaning:
    • Warehouse personnel must perform daily dusting and removal of visible debris from storage units using clean, lint-free cloths.
    • Ensure no raw materials are directly exposed during cleaning; cover materials as needed.
    • Document daily cleaning activities in the Daily Cleaning Log (Annexure-1).
  2. Weekly Cleaning:
    • Conduct thorough weekly cleaning using approved disinfectants. Focus on frequently touched areas such as handles and doors.
    • Inspect for any spillage or contamination and take corrective action if needed.
    • Record weekly cleaning activities in the Weekly Cleaning Log (Annexure-2).

5.2 Deep Cleaning and Disinfection

  1. Monthly Deep Cleaning:
    • Schedule monthly deep cleaning of all storage units, including removing stored materials temporarily to clean the entire area.
    • Use GMP-compliant cleaning agents and ensure the storage units are completely dry before returning materials.
    • Document deep cleaning in the Deep Cleaning Log (Annexure-3).
  2. Post-Cleaning Inspection:
    • QA personnel must inspect the cleaned storage units to ensure no residues or contaminants remain.
    • Approve the cleaned areas for use and document inspections in the Post-Cleaning Inspection Log (Annexure-4).

5.3 Inspection of Storage Units

  1. Routine Visual Inspection:
    • Inspect storage units for signs of rust, damage, or wear that may compromise raw material integrity.
    • Check for signs of pest activity, moisture, or contamination.
    • Document visual inspections in the Storage Unit Inspection Log (Annexure-5).
  2. Corrective Actions for Damaged Units:
    • In case of identified damage, remove affected units from service and initiate repair or replacement.
    • Document corrective actions in the Corrective Action Log (Annexure-6).

5.4 Documentation and Record Keeping

  1. Record Maintenance:
    • Maintain all cleaning and inspection records for a minimum of five years.
    • Ensure records are readily available for internal audits and external inspections.
    • Document record retention in the Record Retention Log (Annexure-7).
  2. Review and Continuous Improvement:
    • QA should review cleaning and inspection logs quarterly and suggest improvements if necessary.
    • Record reviews and updates in the Cleaning Procedure Review Log (Annexure-8).
