Standard Operating Procedure for Cleaning of Labeling Machine

1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to outline the cleaning procedure for a labeling machine used in pharmaceutical manufacturing to ensure product quality, safety, and compliance with Good Manufacturing Practices (GMP).

2. Scope

This SOP applies to all personnel involved in the cleaning of labeling machines within the pharmaceutical manufacturing facility.

3. Responsibilities

• Production Operator: Responsible for initiating the cleaning process.
• Quality Assurance (QA) Inspector: Responsible for verifying the cleanliness of the labeling machine and approving it for further use.
• Supervisor: Oversees the cleaning process and ensures compliance with this SOP.

4. Procedure

4.1. Pre-Cleaning Preparations

1. Notify the Production Supervisor of the need for labeling machine cleaning and obtain necessary approvals.
2. Ensure that the labeling machine is not in operation and is safely isolated from the production process.
3. Wear appropriate personal protective equipment (PPE), including gloves and safety goggles.

4.2. Inspection

1. Visually inspect the labeling machine for any visible residues, contaminants, or blockages.
2. If any residues, contaminants, or blockages are found, note their location and severity for documentation.

4.3. Disassembly (if applicable)

If the labeling machine has removable parts (e.g., labeling heads, belts), follow the manufacturer’s instructions for disassembly before cleaning.

4.4. Pre-Rinse

1. Rinse the exterior of the labeling machine with purified water to remove visible residues or contaminants.
2. Use a soft brush or sponge to gently clean any stubborn residues or deposits.

4.5. Cleaning Solution Preparation

1. Prepare a cleaning solution as per the approved formula and concentration. Refer to the Cleaning Solution Formulation document (if available) for details.
2. Ensure that the cleaning solution is suitable for the materials of construction of the labeling machine and any removable parts.

4.6. Cleaning Process

1. Apply the prepared cleaning solution to the labeling machine’s surfaces, including any disassembled components, using suitable cleaning tools.
2. Scrub the surfaces to remove residues, contaminants, or deposits thoroughly.
3. Rinse the labeling machine and its components with purified water to remove residual cleaning solution.
4. Reassemble the labeling machine if it was disassembled.
5. Repeat the cleaning process as necessary until all residues, contaminants, or blockages are removed.

4.7. Post-Cleaning Inspection

1. Visually inspect the labeling machine after cleaning to ensure that all residues, contaminants, or blockages have been effectively removed.
2. If any issues persist, repeat the cleaning process.

4.8. Final Inspection and Approval

1. Notify the QA Inspector that the labeling machine is ready for inspection.
2. The QA Inspector will visually inspect the machine and document the inspection results.
3. If the machine meets cleanliness criteria, it is approved for further use. If not, the cleaning process is repeated.

4.9. Documentation

Properly document the cleaning process, including cleaning dates, personnel involved, cleaning solutions used, inspection results, and any deviations from the procedure.
