PHARPRO environmental monitoring services
PHARPRO now provides the following cleanroom environmental monitoring services, delivered as a standalone assessment or as part of a qualification, CQV or ongoing monitoring programme:
- 1Air Change Rate (ACR) testing
- 2Non-viable particle counting
- 3Temperature & relative humidity (RH) monitoring
- 4Environmental & thermal mapping
- 5Differential pressure testing
What environmental monitoring should demonstrate
A monitoring program should be based on the facility's EU GMP Annex 1 contamination-control strategy and the activities performed in each area. It must define locations, methods, frequencies, alert and action levels, responsibilities, incubation or analysis conditions, data review, trending and investigation requirements.
Results must be interpreted in context. A single number does not describe control without considering location, activity, personnel, airflow, cleaning status, recovery, historical performance and potential effect on product or process.
Viable and non-viable monitoring scope
Depending on the facility and agreed scope, support can cover active air sampling, settle plates, surface contact plates or swabs, personnel monitoring and non-viable particle counting. PHARPRO can also support air change rate testing, temperature and humidity monitoring, environmental mapping and differential-pressure testing where these parameters form part of the area control strategy.
Testing plans distinguish classification or qualification work from routine operational monitoring. Locations and sampling conditions are selected from process risk, airflow patterns, operator interventions, exposed product pathways and previous data.
Program design, execution and trending
PHARPRO can review or develop monitoring SOPs, sampling maps, forms, limits, frequencies and escalation rules. Execution support includes pre-use checks, traceability, controlled recording, result review and coordination of deviations or excursions.
Trend reports evaluate recurring locations, organisms where microbiological identification is applicable, seasonal changes, shifts by room or activity and performance against established levels. The objective is to detect deterioration before it becomes a product-quality event.
Investigations and remediation
When results exceed established levels or show an adverse trend, the investigation should assess data integrity, sampling technique, personnel practices, cleaning and disinfection, HVAC performance, maintenance, interventions and concurrent events.
PHARPRO supports risk assessment, root-cause evaluation, CAPA definition and effectiveness checks. Where the problem indicates a wider loss of control, additional monitoring, airflow studies, cleaning review, requalification or contamination-control updates may be required.
Frequently asked questions
Is environmental monitoring the same as cleanroom classification?
No. Classification demonstrates airborne particle performance under defined conditions. Routine environmental monitoring evaluates ongoing control during actual operations using a risk-based program.
How are sampling locations selected?
Locations should reflect contamination risk, exposed product and material pathways, critical operations, personnel interventions, airflow and historical performance.
Can PHARPRO review an existing EM program?
Yes. The review can cover procedures, maps, limits, frequencies, methods, data integrity, trending, investigations and alignment with the facility’s contamination-control strategy.
Need this service for your facility or project?
PHARPRO can scope the work, prepare the documentation, coordinate execution and deliver an inspection-ready report package.
