SOP for Nitrogen Purging System

Standard Operating Procedure for Using Nitrogen Purging System

1) Purpose

The purpose of this SOP is to describe the procedure for the proper operation and maintenance of the nitrogen purging system in the pharmaceutical manufacturing of otic dosage forms to ensure the removal of oxygen and prevent oxidation of sensitive materials.

2) Scope

This SOP applies to all personnel involved in the operation and maintenance of nitrogen purging systems in the pharmaceutical manufacturing facility.

3) Responsibilities

Operators: Responsible for correctly operating the nitrogen purging system as per this SOP.
Quality Control (QC) Personnel: Responsible for monitoring and verifying the efficiency of the purging process.
Maintenance Personnel: Responsible for maintaining the nitrogen purging system in proper working condition.

4) Procedure

4.1 Pre-operation Checks
4.1.1 Inspection
4.1.1.1 Inspect the nitrogen purging system for cleanliness and integrity before use.
4.1.1.2 Ensure that all connections are secure and there are no leaks in the system.
4.1.1.3 Verify that the nitrogen supply is sufficient for the intended operation.

4.1.2 Preparation
4.1.2.1 Ensure that the materials to be purged are suitable for nitrogen purging.
4.1.2.2 Set up

the system according to the specific requirements of the product batch.
4.1.2.3 Enter the required parameters into the control panel of the nitrogen purging system.

4.2 Operation
4.2.1 Purging Process
4.2.1.1 Power on the nitrogen purging system and set the desired flow rate.
4.2.1.2 Begin the purging process by introducing nitrogen gas into the system.
4.2.1.3 Monitor the system to ensure that the oxygen levels are reduced to the desired level.
