1. Purpose

This Standard Operating Procedure (SOP) outlines the process for the proper storage of liquid raw materials in compliance with Good Manufacturing Practices (GMP). The goal is to prevent contamination, degradation, and ensure the safety of personnel handling these materials.

2. Scope

This SOP applies to all liquid raw materials stored in the warehouse, including solvents, acids, bases, oils, and temperature-sensitive liquids. It covers storage conditions, container requirements, labeling, and handling procedures to maintain material integrity.

3. Responsibilities

  • Warehouse Personnel: Ensure proper storage conditions for liquid raw materials and report any deviations.
  • Maintenance Team: Maintain storage equipment and ensure that temperature and humidity controls are functioning correctly.
  • Quality Assurance (QA): Conduct audits and verify that storage conditions meet GMP requirements.

4. Accountability

The Warehouse Manager is accountable for the correct storage of liquid raw materials, while the QA Manager is responsible for ensuring that storage practices comply

with GMP guidelines.

5. Procedure

5.1 Storage Conditions for Liquid Raw Materials

  1. Temperature and Humidity Control:
    • Store temperature-sensitive liquids in controlled environments as per the manufacturer’s recommendations.
    • Ensure humidity levels are within acceptable ranges to prevent condensation and contamination.
    • Document temperature and humidity readings in the Liquid Material Environmental Monitoring Log (Annexure-1).
  2. Ventilation:
    • Ensure proper ventilation in storage areas to prevent the accumulation of vapors, especially for volatile liquids.
    • Document ventilation checks in the Ventilation Inspection Log (Annexure-2).

5.2 Container and Packaging Requirements

  1. Container Integrity:
    • Ensure that all containers are leak-proof, sealed correctly, and made of compatible materials with the stored liquid.
    • Inspect containers regularly for signs of leaks, corrosion, or damage.
    • Document inspections in the Container Integrity Inspection Log (Annexure-3).
  2. Secondary Containment:
    • Store liquid raw materials in secondary containment trays to capture leaks or spills.
    • Ensure containment trays are cleaned regularly and inspected for integrity.
    • Record inspections in the Secondary Containment Inspection Log (Annexure-4).

5.3 Labeling and Identification

  1. Labeling Requirements:
    • Ensure all containers are labeled with the material name, batch number, expiration date, and storage conditions.
    • For hazardous liquids, include hazard symbols and safety instructions.
    • Document labeling audits in the Labeling Compliance Log (Annexure-5).
  2. Color Coding:
    • Use color-coded labels or tags to differentiate between different classes of liquids (e.g., flammable, corrosive, non-hazardous).
    • Update the Color Coding Reference Chart (Annexure-6) as needed.

5.4 Handling and Movement of Liquid Raw Materials

  1. Transfer Procedures:
    • Use appropriate pumps and transfer equipment to avoid spills and contamination during material transfer.
    • Ensure personnel are trained in the safe handling of liquid raw materials.
    • Document transfer activities in the Liquid Material Transfer Log (Annexure-7).
  2. Spill Response:
    • In case of spills, follow the spill response procedure outlined in the site’s safety manual.
    • Record spill incidents in the Spill Incident Log (Annexure-8).

5.5 Monitoring and Documentation

  1. Environmental Monitoring:
    • Monitor and record temperature, humidity, and ventilation readings daily.
    • Review data weekly to ensure compliance with storage conditions.
    • Document monitoring in the Environmental Compliance Review Log (Annexure-9).
  2. Deviation Management:
    • Report and investigate any deviations from storage conditions immediately.
    • Document deviations and corrective actions in the Storage Deviation Log (Annexure-10).
