1) Purpose
The purpose of this SOP is to define the procedure for cleaning and maintaining nebulizer dispensing systems to ensure operational efficiency, accuracy, and prevention of contamination.
2) Scope
This SOP applies to all dispensing systems used in the nebulizer manufacturing process within the facility.
3) Responsibilities
Operators: Perform routine cleaning as per this SOP and report any abnormalities.
Maintenance Team: Conduct periodic maintenance, troubleshooting, and repairs.
Quality Assurance (QA): Validate the cleaning and maintenance activities and approve records.
Supervisors: Oversee adherence to cleaning and maintenance schedules.
4) Procedure
4.1 Cleaning Procedure
4.1.1 Pre-Cleaning Activities
- Ensure the dispensing system is turned off and disconnected from the power supply.
- Wear appropriate personal protective equipment (PPE), including gloves and safety goggles.
- Inspect the system for any visible residues or damage.
4.1.2 Cleaning Steps
- Disassemble the dispensing components, such as nozzles, hoses, and reservoirs, following the manufacturer’s guidelines.
- Rinse all removable components with warm, deionized water to remove loose residues.
- Prepare a cleaning solution using an approved detergent and immerse components for the recommended duration.
- Use soft brushes or cleaning swabs to scrub internal surfaces gently.
- Rinse thoroughly with deionized water to remove detergent traces.
- Dry all components using filtered compressed air or lint-free cloths.
- Reassemble the components and conduct a visual inspection to ensure cleanliness.
4.1.3 Cleaning Frequency
- Daily: Clean all parts in direct contact with the product after each production shift.
- Weekly: Perform a comprehensive cleaning of the entire system, including internal pipelines.
4.2 Maintenance Procedure
4.2.1 Routine Maintenance
- Inspect dispensing components for wear, cracks, or clogging.
- Lubricate mechanical parts, such as valves and joints, with food-grade lubricants.
- Test the dispensing accuracy using standard volumetric measurements and adjust settings if needed.
4.2.2 Preventive Maintenance
- Replace worn-out components, such as nozzles and seals, according to the maintenance schedule.
- Inspect and clean the system’s electrical connections and sensors.
- Perform calibration checks on the dispensing system to ensure volume accuracy.
- Document all maintenance activities in the Maintenance Log.
4.2.3 Emergency Maintenance
- Stop the system immediately in case of malfunction or abnormal operation.
- Diagnose the issue and repair or replace faulty components.
- Test the system thoroughly after repairs before resuming production.
4.3 Post-Cleaning and Maintenance Activities
- Ensure the system is dry and free from cleaning agents before restarting.
- Perform a trial run to confirm proper functioning and accuracy of the dispensing system.
- Record cleaning and maintenance details in the Dispensing System Log and submit them to QA for approval.
4.4 Safety Precautions
- Always use PPE while cleaning and maintaining the dispensing system.
- Follow the manufacturer’s instructions for disassembly and reassembly.
- Avoid using abrasive tools that may damage delicate components.
- Ensure all cleaning agents are compatible with the materials of the dispensing system.
