SOP for Use of Nebulizer Leak Testing Equipment

Standard Operating Procedure for Using Nebulizer Leak Testing Equipment

1) Purpose

The purpose of this SOP is to establish a standardized procedure for the use of leak testing equipment to ensure that nebulizer units are free of leaks and meet quality standards.

2) Scope

This SOP applies to all leak testing equipment used in the quality assurance of nebulizers during the manufacturing process.

3) Responsibilities

Operators: Operate the leak testing equipment and record results accurately.
Quality Assurance (QA): Validate the results of leak tests and approve testing records.
Maintenance Team: Ensure the leak testing equipment is calibrated and functioning properly.

4) Procedure

4.1 Pre-Test Checks

Inspect the leak testing equipment for cleanliness and proper functioning.
Verify that the equipment is calibrated as per the schedule and within its calibration validity.
Ensure the appropriate test fixtures and adapters are available for the nebulizer units to be tested.
Document the equipment details and test setup in the Leak Testing Log.

4.2 Preparing the Nebulizer for Testing

Visually inspect the nebulizer unit for any visible damage or defects.
Assemble the nebulizer unit as per the test specifications.
Connect the unit to the leak testing equipment using the appropriate adapters or fixtures.

4.3 Conducting the Leak Test

Activate the

equipment and set the testing parameters, such as pressure, vacuum, and test duration, according to the product specifications.

Run the test and monitor the equipment display for any deviations or leak indications.

Record the results, including pass or fail status, in the Leak Testing Report.

If a unit fails the test, mark it as “Rejected” and segregate it for further investigation.

4.4 Post-Test Activities

Disconnect the nebulizer unit and inspect the testing equipment for residual materials or wear.
Clean the equipment as per the cleaning SOP to prepare it for the next use.
Submit the test results to the QA team for validation and approval.
Document the completion of the test in the Leak Testing Log.

4.5 Safety Precautions

Wear personal protective equipment (PPE), such as gloves and safety glasses, while handling nebulizer units and testing equipment.
Ensure that all connections are secure to avoid accidents during pressurized tests.
Follow the manufacturer’s safety guidelines for operating the leak testing equipment.

5) Abbreviations

QA: Quality Assurance
PPE: Personal Protective Equipment
