- Define sampling locations for Environmental Monitoring in cleanrooms: Identify critical locations within the clean room where samples need to be taken. These locations should be determined based on the risk assessment of the clean room and should include areas where there is a higher chance of microbial contamination.
- Develop a sampling plan for Environmental Monitoring of clean rooms: A sampling plan should be developed that outlines the frequency of sampling, the number of samples to be taken, and the methods to be used for each location. The sampling plan should be based on the risk assessment and should be reviewed periodically.
- Use validated equipment: Ensure that the equipment used for environmental monitoring is validated and calibrated.
- Follow aseptic techniques during Environmental Monitoring: When taking samples, ensure that aseptic techniques are followed to prevent contamination of the sample.
- Document and trend results: Environmental monitoring results should be documented and trended over time. This helps to identify any changes in the microbial population within the clean room and to determine if corrective actions are necessary.
- Respond to excursions: If any environmental monitoring results are out of specification, take appropriate corrective actions, investigate the root cause, and document the findings. This helps to prevent future excursions and ensure that the clean room environment remains in a state of control.
