SMOKE-STUDIES-1280x1280.jpg

Cleanroom smoke studies are critical assessments used to evaluate cleanrooms’ airflow patterns and containment capabilities, particularly in pharmaceutical and biotechnology manufacturing environments. These studies involve introducing harmless smoke or vapour into the cleanroom to visualize airflow, identify turbulence, and assess the effectiveness of ventilation systems.

Regulatory authorities like the FDA, EU-GMP, and others emphasize the need for smoke studies during the cleanroom qualification and requalification processes. They help ensure cleanrooms are properly designed to protect product quality by maintaining a controlled environment.

Purpose of Smoke Studies

  1. Airflow Visualization: To understand how air moves within the cleanroom.
  2. Containment Assessment: To ensure that airborne contaminants do not escape from controlled areas.
  3. Regulatory Compliance: To demonstrate adherence to industry standards and regulations.
  4. Operational Improvements: To identify potential areas for design improvement or operational adjustments.

Step-by-Step Process for Performing Smoke Studies

  1. Preparation:
    • Define Objectives: Clearly outline the goals of the study.
    • Select Smoke Source: Choose an appropriate smoke source (e.g., smoke tubes, aerosol generators).
    • Environmental Conditions: Ensure the cleanroom is operating under normal conditions.
  2. Test Plan Development:
    • Design Test Scenarios: Identify specific areas or conditions to be tested (e.g., near equipment, personnel flow).
    • Determine Acceptance Criteria: Set parameters for acceptable airflow and containment.
  3. Execution:
    • Introduce Smoke: Generate and release smoke in the cleanroom while maintaining normal operations.
    • Observation: Use visual or recorded methods (e.g., video) to track smoke movement and behaviour.
    • Data Collection: Document observations systematically, noting areas of turbulence, stagnation, or leakage.
  4. Analysis:
    • Review Data: Analyze the collected data against the acceptance criteria.
    • Identify Issues: Highlight any airflow irregularities or containment failures.
  5. Reporting:
    • Prepare Report: Document findings, methodology, and recommendations.
    • Review and Revise: Ensure the report meets regulatory and internal standards.
  6. Follow-Up Actions:
    • Implement Changes: If issues are identified, initiate corrective actions.
    • Re-test if Necessary: Conduct additional studies post-modifications to confirm improvements.
