Cleanroom Repair, Servicing, and Maintenance

   

• Equipment Malfunctions: Any equipment within the cleanroom, from HEPA filters to laminar flow units, must be promptly repaired when malfunctions occur. This includes fixing or replacing parts like pre-filters, fans, or control systems that maintain air quality and flow.
• Structural Integrity: Repairing any breaches or damage to cleanroom walls, ceilings, or floors to prevent contamination. This might involve sealing cracks, repairing air-tight seals, or replacing damaged panels.
• Emergency Repairs: Facilities should have a plan for emergency repairs to address sudden failures, like HVAC system breakdowns, where downtime could compromise patient safety or product integrity.

 

• HVAC Systems: Regular servicing of the heating, ventilation, and air conditioning systems is crucial to maintain the requisite temperature, humidity, and air quality. This includes checking air changes per hour, differential pressure, and ensuring HEPA or ULPA filters are functioning correctly.
• Monitoring Systems: Calibration and maintenance of environmental monitoring systems to ensure they accurately measure particles, temperature, humidity, and pressure within the cleanroom.
• Scheduled Inspections: Conducting periodic checks based on the cleanroom's ISO classification to assess equipment performance, like testing airflow patterns or filter integrity.

 

• Daily Cleaning: Routine cleaning is essential to maintain cleanliness standards. This involves using specialized products and techniques to clean surfaces without introducing contaminants. Cleaning tasks include wiping down walls, ceilings, floors, and furniture with cleanroom-approved materials.
• Disinfection: Regular disinfection to control microbial growth. This includes using appropriate disinfectants for the specific cleanroom grade, ensuring compatibility with cleanroom materials.
• Filter Replacement: Filters, especially HEPA and ULPA types, must be replaced according to manufacturer recommendations or when performance monitoring indicates degradation.
• Personnel Training: Ongoing training for staff on cleanroom protocols to minimize human sources of contamination. This includes gowning procedures, movement within the cleanroom, and handling of materials.
• Preventative Maintenance: Implementing a schedule for preventative measures, like checking for wear and tear on cleanroom garments, replacing worn seals on doors, or ensuring that all fixtures and fittings are securely in place to prevent particle generation.
• Certification and Compliance: Regular certification to ensure the cleanroom meets regulatory standards. This might involve third-party validation of cleanliness levels, airflow, and other environmental controls.
• Contingency Planning: Preparing for potential issues with a stock of essential parts for quick replacement and ensuring there are protocols for unexpected maintenance needs.
