Standard Operating Procedure for Thermal Mapping of Equipment
1) Purpose
The purpose of this SOP is to establish procedures for conducting thermal mapping studies on equipment used in the manufacturing of dental dosage forms, including pastes, gels, and mouthwashes. Thermal mapping ensures uniform temperature distribution within equipment to maintain product quality and comply with regulatory requirements.
2) Scope
This SOP applies to all equipment and machinery used in pharmaceutical manufacturing processes for dental dosage forms. It includes procedures for performing thermal mapping studies, analyzing temperature data, and implementing corrective actions to optimize equipment performance.
3) Responsibilities
The Quality Assurance (QA) Department is responsible for implementing and overseeing thermal mapping studies. The Production Department is responsible for conducting thermal mapping activities, and the Engineering Department provides technical support. All personnel involved in thermal mapping are responsible for following these procedures and reporting any deviations promptly.
4) Procedure
4.1 Study Preparation
4.1.1 Define the objectives, scope, and acceptance criteria for the thermal mapping study based on regulatory guidelines and internal standards.
4.1.2 Identify critical equipment and areas requiring temperature mapping, including heating chambers, ovens, incubators, and refrigerators.
4.1.3 Obtain necessary approvals for the thermal mapping study plan from QA and relevant stakeholders.
4.2 Data Acquisition
4.2.1 Install temperature sensors (thermocouples
4.2.2 Ensure sensors are calibrated and positioned to capture representative temperature readings during equipment operation.
4.2.3 Perform temperature mapping studies under normal operating conditions, including worst-case scenarios and peak load conditions.
4.3 Data Analysis
4.3.1 Collect temperature data from sensors at specified intervals throughout the mapping study.
4.3.2 Analyze temperature data to assess uniformity and distribution within the equipment, comparing results against predefined acceptance criteria.
4.3.3 Generate graphical representations (temperature maps) and statistical analyses (mean, maximum, minimum temperatures) to document temperature profiles.
4.4 Corrective Actions
4.4.1 Identify any temperature deviations or non-uniformities that exceed acceptance criteria during data analysis.
4.4.2 Implement corrective actions, such as equipment adjustments, recalibration of sensors, or procedural changes, to optimize temperature uniformity.
4.4.3 Document all corrective actions taken and verify effectiveness through repeat thermal mapping studies as necessary.
4.5 Reporting and Documentation
4.5.1 Prepare a comprehensive thermal mapping report summarizing study objectives, methods, results, conclusions, and recommendations.
4.5.2 Obtain approval of the thermal mapping report from QA and relevant stakeholders before equipment use.
4.5.3 Maintain complete documentation, including thermal mapping protocols, raw data, analysis reports, corrective action records, and approval records.
