Verify that blending operations are carried out in accordance with the defined procedures.
Monitor compliance with safety regulations and GMP during blending operations.
3.2. Blending Operator:
Perform blending operations as per the documented procedures.
Follow safety guidelines and wear appropriate personal protective equipment (PPE) during blending operations.
Report any abnormalities, equipment malfunctions, or quality issues to the Production Supervisor.
Procedure:
4.1. Pre-Blending Preparations:
a. Gather the necessary raw materials, excipients, and blending equipment required for the blending process.
b. Verify that all raw materials and excipients are properly labeled and correspond to the batch record.
c. Ensure that the blending equipment is clean, properly assembled, and in good working condition.
4.2. Blending Process:
a. Review the batch record
b. Set the blending equipment controls as per the specified parameters in the batch record.
c. Load the required raw materials and excipients into the blending equipment as per the batch record instructions.
