Cleanroom Environmental Monitoring Inspection Checklist [FREE PDF]

Cleanroom environmental monitoring is a mandatory quality control activity governed by ISO 14644-1/2, GLP regulations under 21 CFR 58, and CAP accreditation standards for laboratories producing or testing regulated products. Routine monitoring of airborne particulate counts, differential pressure, temperature, relative humidity, and microbial contamination is essential to demonstrating that the controlled environment meets its classified ISO grade at all times.

Pre-Monitoring Setup & Equipment Verification

Confirm monitoring instruments are calibrated, operational, and properly configured before data collection.

  • Is the particle counter within its current calibration period with a valid calibration certificate on file?
  • Has the particle counter been zeroed and background-counted in HEPA-filtered air prior to monitoring?
  • Are all environmental monitoring instruments (thermometer, hygrometer, manometer) within calibration?
  • Have the monitoring sample locations been selected per the approved monitoring plan and risk-based site map?
  • Are all personnel entering the cleanroom for monitoring gowned per the facility gowning SOP?

Airborne Particulate Monitoring

Record particle counts at defined locations and verify against ISO classification limits.

  • Were particle counts recorded at all designated sampling locations per the monitoring plan?
  • Did all 0.5 µm particle counts at all sample locations meet or remain below the ISO class limit?
  • Did all 5.0 µm particle counts (where applicable) meet or remain below the ISO class limit?
  • Was each sample volume collected at a minimum of 2 liters per minute for at least 1 minute per location?
  • Were any alert or action limit exceedances observed and documented with immediate notification to QA?
  • Please record the highest 0.5 µm particle count observed across all sampling locations (particles/m³)?

Differential Pressure & Airflow Velocity

Verify room pressure cascades and HEPA filter face velocities are within specification.

  • Is the positive pressure differential between the cleanroom and adjacent lower-grade area within specification (minimum 10-15 Pa)?
  • Please record the current differential pressure reading between the cleanroom and the adjacent corridor (Pa)?
  • Is the HEPA filter face velocity within the specified range (typically 0.45 m/s ± 20% for ISO 5 unidirectional)?
  • Are all pressure monitoring alarms and continuous monitoring displays functioning correctly?
  • Are all HEPA filter integrity test results current (within 12 months) with no documented failures?

Temperature & Relative Humidity Control

Record and evaluate temperature and humidity against facility specifications and product requirements.

  • Is the cleanroom temperature within the facility-specified range for this area?
  • Please record the current cleanroom temperature?
  • Is the relative humidity within the facility-specified range (typically 30-60% RH for most cleanrooms)?
  • Please record the current relative humidity reading (%RH)?
  • Are temperature and humidity data logger readings reconciled with manual readings within acceptable tolerance (±0.5°C / ±2% RH)?

Microbial Contamination Monitoring

Assess airborne and surface microbial contamination levels against cleanroom classification limits.

  • Were active air samples collected using calibrated impaction sampler at all designated microbial monitoring locations?
  • Were settle plates (90mm diameter TSA) exposed for the required duration at critical and non-critical zones?
  • Were contact plates (RODAC) used for surface monitoring of critical surfaces and equipment?
  • Were personnel monitoring glove-prints and gown contact plates collected from operators working in ISO 5 or critical zones?
  • Have all microbial sample plates been labeled, transported, and submitted to microbiology within the required hold time?
  • Are previous microbial monitoring results within alert and action limits with no unresolved exceedances?

Gowning & Personnel Control Assessment

Evaluate personnel entry procedures, gowning compliance, and behavior controls in the cleanroom.

  • Are all personnel in the cleanroom wearing full appropriate gowning for the ISO classification (including gloves, mask, hair cover)?
  • Is the gowning anteroom (if applicable) being used correctly with the proper gowning sequence followed?
  • Is the number of personnel in the cleanroom within the validated occupancy limit for the room?
  • Are personnel following correct behavior protocols (no rapid movements, no cosmetics, no prohibited items)?
  • Are gowning qualification records current for all personnel currently authorized to enter this cleanroom?

Cleanroom Housekeeping & Disinfection

Verify cleaning and disinfection schedules are current and all surfaces are in acceptable condition.

  • Has the cleanroom been cleaned and disinfected according to the current cleaning schedule prior to monitoring?
  • Are cleaning agents and disinfectants used approved, within expiration date, and prepared at the correct use-dilution?
  • Are all surfaces (floors, walls, equipment, work surfaces) visually clean and free of residue, stains, or visible particles?
  • Are all items in the cleanroom approved, necessary, and decontaminated prior to introduction?
  • Please document any observations, non-conformances, corrective actions, or follow-up items identified during this monitoring session?
