Standard Operating Procedure (SOP) for Maintenance of GMP Facility Cleanrooms

Download the free Template

Introduction:
Preserve critical manufacturing conditions and ensure regulatory compliance with our Standard Operating Procedure (SOP) for Maintenance of GMP Facility Cleanrooms. Specifically designed for pharmaceutical, biotechnology, and medical device companies operating under cGMP standards (21 CFR Parts 210/211, EU GMP Annex 1, and ISO 14644), this SOP provides detailed procedures for cleaning, maintenance, inspection, and control of classified cleanroom environments.

Overview:
The SOP for Maintenance of GMP Facility Cleanrooms establishes a standardized protocol to manage environmental conditions and prevent contamination risks within controlled environments. It defines specific responsibilities, procedures, frequencies, and documentation requirements to ensure cleanrooms remain compliant, validated, and fully functional for aseptic and non-aseptic operations.

Key Sections Included in the SOP:

1. Purpose:
   Defines the objective of ensuring that GMP cleanrooms are maintained in a state of control to support product safety, sterility assurance, and regulatory compliance.
2. Scope:
   Applies to all classified areas, including ISO Class 5 to 8 cleanrooms, airlocks, gowning areas, and material/equipment transfer zones used in production, QC labs, or sterile processing environments.
3. Responsibilities:
   • Facilities and Engineering: Perform scheduled maintenance and system checks.
   • Quality Assurance (QA): Review and approve maintenance activities, investigate deviations.
   • Operations/Production: Maintain adherence to procedures during routine activities.
   • Cleaning Staff: Execute cleaning protocols and record entries.
4. Cleanroom Classification and Requirements:
   • Defines classification per ISO 14644-1 and applicable regulatory requirements.
   • Identifies area-specific maintenance and environmental control expectations.
5. Cleaning and Sanitization Procedures:
   • Step-by-step instructions for daily, weekly, and monthly cleaning tasks.
   • Includes use of validated disinfectants, sterile wipes, and cleaning equipment.
   • Rotational disinfection strategy to minimize microbial resistance.
   • Guidelines for cleaning spills and handling breakages.
6. Scheduled Maintenance and Inspections:
   • Details HVAC inspections, HEPA filter integrity testing, pressure differential checks, light and surface integrity, and floor/wall/ceiling inspections.
   • Includes frequency (daily, weekly, monthly, quarterly, annually) based on risk and area classification.
7. Preventive Maintenance Program:
   • Covers air handling units, pressure gauges, temperature/humidity sensors, and monitoring systems.
   • Describes coordination between maintenance and QA to avoid contamination and downtime.
8. Environmental Monitoring Integration:
   • Coordinates with environmental monitoring (EM) plans to detect microbial or particulate excursions related to poor maintenance.
   • Defines responses to EM alerts or failures caused by inadequate maintenance.
9. Use of Materials and Equipment:
   • Lists approved cleaning materials, tools, and maintenance supplies.
   • Requires cleanroom-compatible, non-shedding, and sterile components for use in critical areas.
10. Change Control and Deviation Handling:

• All changes in cleaning materials, methods, or maintenance equipment require change control approval.
• Deviations from procedures must be investigated and documented with appropriate CAPAs.

1. Documentation and Recordkeeping:

• Cleaning logs, maintenance reports, equipment calibration records, and EM trend reports must be completed contemporaneously and stored per GDP.
• Logs must include time, date, responsible personnel, and QA review.

1. Training and Qualification:

• Personnel entering or maintaining cleanrooms must be trained and qualified in gowning, behavior, and cleaning techniques.
• Includes periodic retraining and requalification in aseptic environments.

1. Audit and Inspection Readiness:

• Cleanroom maintenance documentation must be available during internal audits and regulatory inspections.
• Ensures traceability and compliance with FDA, EMA, and ISO expectations.

Why Download This SOP?

• Maintain GMP Compliance: Aligns with EU Annex 1, ISO 14644, and FDA expectations for cleanroom control.
• Protect Product Integrity: Reduces risk of microbial and particulate contamination.
• Ensure Repeatability and Consistency: Standardizes cleanroom maintenance across shifts and teams.
• Be Audit-Ready: Maintain comprehensive records and validations for inspections.
• Support Aseptic Manufacturing: Critical for sterility assurance in classified environments.
