Where to start the inspection?
• Facility layout
•Flow of personnel and
material, activities
• Product list
•Type of products, dosage
forms, activities
• Utilities (HVAC, water, etc)
• Validation status

Batch Manufacturing Document
• Formula and manufacturing steps
• API and excipients
• Properties and requirements for
temperature or RH control
• Material quantities, batch size
• Sub lots
• Equipment and utilities
• Production areas
Equipment and utilities (1)
Sieving/sifting – sifter (e.g. vibrosifter)
Mixing – mixer
Granulation - granulator
Drying – fluid bed drier
Blending – octagonal blender
Compression – compression machine
Packaging - blister machine
Others include Metal detector, sieves,
punches and dies
In process quality control instruments and
equipment may include hardness tester,
disintegration tester, balance, caliper
Equipment and utilities (2)
• HVAC – air supply and extraction
• Compressed air – machine
operation, drying of equipment and
parts
• Water – washing, rinsing,
manufacture
• Steam – cleaning
Utilities
The environment may be influenced by:
• Light
• Temperature
• Humidity
• Air movement
• Microbial contamination
• Particulate contamination
• Uncontrolled environments can lead to:
• Product degradation
• Product contamination
• Loss of Product & Profit
Utilities
HVAC: GMP and GEP
• Effective ventilation
• Cross-contamination and
contamination
• Qualification/validation
• Design
• Installation
• Operation
• Performance

Problems with components
Filters Incorrect retention rate/leaking/badly
installed
Fan Low air flow ® loss of pressure cascade
Flow rate controller Blocked ® poor pressure cascade ® cross-
contamination
Control damper Poorly adjusted, bad pressure differential
system
Humidifier Bad water/steam quality/poor drainage/
Cooling coil No elimination of condensed water/poor
drainage/stagnating water
Ducts Inappropriate material/internal insulation
Leaking ducts
Utilities: Water systems
• Type of water
• Intended use
• Quality (specification)

• Qualification and validation
• Ongoing monitoring and quality
control
• Sampling, testing, trends
