SOP for Cleaning and Sterilizing Nebulizer Transfer Lines

Standard Operating Procedure for Cleaning and Sterilizing Nebulizer Transfer Lines

1) Purpose

The purpose of this SOP is to establish a standardized procedure for cleaning and sterilizing nebulizer transfer lines to ensure contamination-free transfer of materials and maintain product quality.

2) Scope

This SOP applies to all transfer lines used in the production and transfer of nebulizer solutions and components within the manufacturing facility.

3) Responsibilities

Operators: Perform cleaning and sterilization activities as per the defined procedure.
Maintenance Team: Ensure the proper functioning of cleaning and sterilization equipment.
Quality Assurance (QA): Verify cleaning effectiveness and maintain related records.

4) Procedure

4.1 Pre-Cleaning Preparation

Inspect the transfer lines for any visible debris, residue, or damage.
Ensure all necessary cleaning agents, sterilizing solutions, and tools are available and validated for use.
Disconnect the transfer lines from equipment or containers while ensuring minimal spillage or contamination.
Wear appropriate personal protective equipment (PPE), including gloves, goggles, and lab coats.

4.2 Cleaning Process

Flush the transfer lines with purified water to remove loose particles and residues.
Prepare the cleaning solution as per the approved protocol and fill the cleaning tank or pump system.
Recirculate the cleaning solution through the transfer lines for the specified duration to dissolve any

remaining residues.

Rinse the lines thoroughly with potable water, followed by a rinse with purified water to remove cleaning agent residues.

Perform a final rinse with water for injection (WFI) to ensure sterility.

4.3 Sterilization Process

Attach the transfer lines to the sterilization system (e.g., autoclave or steam sterilizer).
Set the sterilization parameters, such as temperature, pressure, and duration, as per the equipment’s operational manual.
Start the sterilization cycle and monitor the system to ensure the parameters are maintained throughout the process.
After sterilization, allow the lines to cool before handling to prevent damage or injury.

4.4 Post-Sterilization Activities

Inspect the sterilized lines visually to ensure there is no damage or residue.
Reconnect the transfer lines to the respective equipment or storage containers under aseptic conditions.
Label the lines with the cleaning and sterilization date, next due date, and operator initials.
Document all activities in the Cleaning and Sterilization Log.

4.5 Frequency of Cleaning and Sterilization

Routine: After every batch or production cycle.
Deep Cleaning: Weekly or after handling highly viscous or reactive materials.
Emergency Cleaning: Immediately after any contamination or spillage.

4.6 Safety Precautions

Ensure proper handling and disposal of cleaning agents as per their Material Safety Data Sheets (MSDS).
Follow lockout/tagout (LOTO) procedures during maintenance or troubleshooting.
Avoid direct contact with hot surfaces during sterilization processes.
