Purpose: To detect the presence of microorganisms (bacteria, fungi) in the environment and on surfaces, indicating biocontamination.

Method:

• Air Quality Monitoring: Passive Methods: Settling plates (for general microbial fallout).
  Active Methods: Active air samplers (impaction onto agar plates for precise microbial counts).
• Surfaces: Contact plates (RODAC) or moistened swabs on critical areas (equipment surfaces, floors, walls)
• Personnel: Glove and Garment Sampling

Purpose: Ensure that cleaner areas maintain positive pressure relative to adjacent less-clean areas to prevent contamination ingress.

Method: Differential pressure gauges are used to continuously measure and record the pressure difference between the different zones.

Purpose: To verify that air flows uniformly and at the correct velocity, especially in unidirectional (laminar) flow areas such as cabins or isolators.

Method: We use anemometers to measure air velocity and employ smoke generation techniques (or “smoke tests”) to visualize airflow patterns and ensure there are no eddies or dead zones.

Purpose: To verify that High-Efficiency Particulate Air (HEPA) and Ultra-Low Penetration Air (ULPA) filters are leak-free and functioning correctly.

Method: Aerosol Leak Testing (e.g., DOP/PAO Test). This involves introducing an aerosol at the filter’s inlet and scanning the filter surface with an aerosol photometer to detect leaks.

Purpose: To maintain environmental conditions within specified ranges, ensuring both product stability and personnel comfort.

Method: Continuous monitoring with calibrated sensors, with alarms in case of deviations.

Purpose: To assess a cleanroom’s ability to return to its specified clean state after a particle-generating event (e.g., entry of personnel or materials).

Method: Controlled introduction of a particle aerosol and measurement of the time it takes for the room to return to its cleanliness classification.

Purpose: For the pharmaceutical and veterinary sectors, the quality of water used in production or cleaning is critical.

Method: Physicochemical analysis (conductivity, TOC – Total Organic Carbon) and microbiological analysis (total microbial count, detection of specific pathogens, endotoxins).

Purpose: To ensure that all measuring instruments and equipment in the facility operate with precision and reliability, guaranteeing compliance with current regulations.

Method: Key sensors and devices such as pressure and temperature probes, humidity sensors, flowmeters, pH meters, level sensors, and other critical equipment are calibrated using certified reference standards and standardized procedures. The results are meticulously documented to maintain traceability and facilitate audits.

Purpose: To verify and document that the design of the facility, equipment, or system complies with the regulatory, safety, and operational requirements defined by the user and current legislation.

Method: Review of technical documentation, analysis of specifications, risk assessment, and verification that the proposed design is suitable for its intended purpose and compatible with applicable regulations. A DQ (Design Qualification) protocol is generated, containing all evidence and justifications.

Purpose: To ensure that the installation of the equipment or system has been carried out in accordance with the approved design, and that all critical components are correctly installed and documented.

Method: Physical inspection, documentation review (manuals, material certificates, blueprints), and verification of connections, utilities, and auxiliary systems. The conformity of each key element concerning the design and regulatory requirements is documented in the IQ protocol.

Purpose: To demonstrate that the equipment or system functions correctly within defined operating limits and under all anticipated conditions of use.

Method: Execution of functional tests, operational simulations, and verification of alarms, controls, and critical parameters. The results of each test are documented, and operational parameters are adjusted if necessary. The OQ protocol compiles all evidence of operation in accordance with the requirements.

Purpose: To confirm that the equipment, system, or process produces consistent and reproducible results under real operating conditions, including both normal situations and extreme limits.

Method: Performance tests are conducted under routine conditions and in scenarios of maximum demand. Performance data is collected, system robustness is evaluated, and conformity with the acceptance criteria defined in the PQ protocol is documented.

Purpose: To identify, evaluate, and control risks associated with facilities, equipment, and processes, prioritizing preventive actions to ensure safety, quality, and regulatory compliance.

Method: We apply methodologies such as FMEA (Failure Modes and Effects Analysis), HACCP, or criticality analysis. Critical points are identified, probabilities and impacts are evaluated, and controls and mitigation measures are established. The entire process is documented and periodically reviewed.

Purpose: To establish the overall strategy and planning for all validation and qualification activities of a facility, equipment, or system, ensuring comprehensive compliance with regulatory requirements.

Method: Validation Master Plan (VMP). This involves developing a master document that defines the scope, acceptance criteria, responsibilities, timelines, and required documentation for each stage of validation and qualification. The VMP serves as a central reference for audits and regulatory reviews.

Purpose: To ensure that the equipment has been correctly installed in accordance with manufacturer specifications, drawings, and regulations.

Tests/Controls:

• Verification of Correct Installation of Components, Piping, and Connections
• Verification of Correct Installation of Components, Piping, and Connections
• Verification that auxiliary services (water, air, steam) have been installed with the required quality.
• Verification of Technical Documentation and Manuals
• Verification of Equipment Construction Materials in Contact with the Product

Purpose: To demonstrate that the equipment consistently operates within the defined operating ranges (including upper and lower limits).

Tests/Controls

• Functional Testing of All Equipment Components and Subsystems
• Verification of Alarms, Interlocks, and Safety Functions
• Critical Equipment Control Point Testing (e.g., temperature, pressure, speed, dosage control) within their operational ranges.
• Verification of Operational Repeatability

Purpose: To demonstrate that the equipment functions consistently and reproducibly for the specific process or product it was designed for under actual use conditions.

Tests/Controls:

• Production of product batches under normal operating conditions, demonstrating that a product meeting quality specifications is obtained.
• Stability, uniformity, purity, etc. tests of the product processed by the equipment.

This is often linked with process validation.

Purpose: To ensure that the equipment’s measuring instruments (thermometers, pressure gauges, scales, flow meters, etc.) provide accurate readings within acceptable tolerances.

Method: Comparing instrument readings with a traceable reference standard, at defined intervals.

Purpose: To ensure the reliability and continuous proper functioning of equipment.

Method: Establishing maintenance programs based on manufacturer recommendations, experience, and risk analysis.

Purpose: To demonstrate that equipment cleaning procedures are effective in removing product residues, detergents, and microorganisms, thereby preventing cross-contamination.

Method: Surface sampling (swabs, rinses) after cleaning and analysis of chemical or microbiological residues.
