environmental monitoring system complies with GMP standards and that records are complete, accurate, and readily available for inspection.

Maintenance Team: Responsible for ensuring that HVAC systems, filters, and other environmental control systems are properly maintained and functioning according to specifications.

4. Accountability

The Head of Creams Manufacturing is responsible for ensuring the implementation of this SOP in the manufacturing areas. The QA Manager is accountable for ensuring that all environmental monitoring activities are conducted according to this SOP and that any deviations are promptly addressed.

5. Procedure

5.1 Environmental Monitoring Plan

1. Develop and maintain an environmental monitoring plan that includes the following key parameters:
   • Air quality (particulate levels, microbial contamination)
   • Temperature
   • Humidity
   • Surface cleanliness (e.g., microbial testing of surfaces in critical areas)
2. The monitoring plan should define the frequency of checks, the equipment used, and the areas to be monitored in each manufacturing zone.
3. The plan should be reviewed annually and updated as needed to ensure compliance with GMP and regulatory requirements.

5.2 Air Quality Monitoring

1. Conduct air quality monitoring to measure particulate matter and microbial contamination levels in the manufacturing areas.
2. Air quality testing should be conducted using validated particle counters and microbial air samplers.
3. Monitoring should be done at regular intervals during production, with more frequent checks in high-risk areas, such as filling and packaging zones.
4. Ensure that the air quality meets the specified limits for particulate matter (e.g., less than 100 particles per cubic meter) and microbial contamination (e.g., no more than 10 CFUs per cubic meter).
5. If air quality fails to meet the specifications, identify the source of contamination, address the issue (e.g., HVAC system adjustments), and re-test the air quality.

5.3 Temperature and Humidity Monitoring

1. Monitor temperature and humidity levels in the manufacturing areas regularly to ensure they remain within the specified range. For most cream manufacturing processes, temperature should be maintained between 20°C and 25°C, and humidity should be kept between 40% and 60%.
2. Use calibrated temperature and humidity sensors placed in various locations throughout the manufacturing area to continuously record data.
3. If temperature or humidity levels fall outside the specified range, initiate corrective actions, such as adjusting the HVAC system, and document any deviations in the batch record.

5.4 Surface Cleanliness Monitoring

1. Conduct surface cleanliness monitoring by sampling critical surfaces (e.g., mixing vessels, counters, equipment) for microbial contamination at specified intervals.
2. Use contact plates, swabs, or other validated methods to collect samples and send them to the QC lab for microbial testing.
3. Ensure that all surfaces meet the required standards for microbial contamination (e.g., no more than 1 CFU per 10 cm² in clean areas).
4. If any surfaces exceed the acceptable microbial limits, take corrective actions such as additional cleaning, sanitization, or equipment replacement.

5.5 Equipment Calibration and Maintenance

1. Ensure that all environmental monitoring equipment, including particle counters, air samplers, temperature and humidity sensors, are calibrated regularly to maintain accuracy.
2. The Maintenance Team should conduct routine checks and calibration of environmental control systems (e.g., HVAC, air filtration systems) according to the manufacturer’s specifications and internal standards.
3. Maintain records of equipment calibration and maintenance, and ensure that any deviations or malfunctions are documented and resolved promptly.

5.6 Documentation and Reporting

1. Document all environmental monitoring activities in the Environmental Monitoring Log, including test results, corrective actions taken, and any deviations from specified limits.
2. Ensure that batch records include relevant environmental data (e.g., air quality, temperature, humidity) for traceability and compliance purposes.
3. QA must review and approve all environmental monitoring records and ensure that they are available for inspection during internal audits or regulatory inspections.

5.7 Corrective and Preventive Actions (CAPA)

1. If any environmental monitoring results fall outside acceptable limits, initiate a Corrective and Preventive Action (CAPA) process to investigate the root cause of the deviation and implement corrective measures.
2. Document all CAPA actions, including investigations, root cause analysis, corrective actions, and preventive measures, in the CAPA Log.
3. Review the effectiveness of corrective actions during subsequent monitoring sessions to ensure the issue has been resolved.

5.8 Final Approval

1. Once all environmental monitoring parameters are within acceptable limits and corrective actions have been implemented, QA must approve the batch for further processing or packaging.
2. Ensure that all environmental monitoring records are properly archived and accessible for review during future audits or inspections.
