Standard Operating Procedure for Out of Specification (OOS) Handling in Gels Production
1) Purpose
The purpose of this SOP is to establish procedures for the identification, investigation, and handling of Out of Specification (OOS) results encountered during gels production, ensuring accurate data interpretation, product quality assessment, and compliance with regulatory requirements.
2) Scope
This SOP applies to all personnel involved in the pharmaceutical manufacturing facility’s gels production department, including Quality Assurance (QA), Quality Control (QC), and Production personnel responsible for OOS investigations.
3) Responsibilities
Quality Assurance (QA) Team: Oversee OOS investigation process and ensure compliance with SOPs.
Quality Control (QC) Analysts: Perform initial OOS investigation and data review.
Production Supervisors: Provide support and necessary information for OOS investigations.
4) Procedure
4.1 OOS Result Identification
4.1.1 Identify and document any test result that falls outside established acceptance criteria or specifications.
4.1.2 Classify the OOS result based on significance and potential impact on product quality.
4.2 Initial Assessment and Documentation
