Validation & Post Validation Monitoring Reefer Validation Done Right David Ulrich Abbott Laboratories, QA Distribution Manager
What is Validation? • According to the Food and Drug Administration (FDA), the goal of validation is to: “[Establish] documented evidence which provides a high degree of assurance that a specific process will consistently produce a product meeting its pre-determined specifications and quality attributes.” - FDA, Guideline on General Principles of Process Validation
How do we Validate? • FDA’s Center for Drug Evaluation & Research (CDER) General Principles of Process Validation: • Installation Qualification (IQ) • Insures that the system/equipment and its components are installed correctly and to the original manufacturer’s specifications. • Operational Qualification (OQ) • The OQ, tests are performed on the critical parameters of the system/process. These are usually the independent and/or manipulated variables associated with the system/equipment • Performance Qualification (PQ) • This phase tests the ability of the process to perform over long periods of time within tolerance deemed acceptable.
Validation is NOT new for Pharma Mfg’ers (nor the FDA) • We currently execute validations on: • Methods, Assays, cleaning, recovery, E/U/F, computers, water systems (PW, DW, PO, WFI, etc), Lab instruments, etc • Processes (process validation); fill/finish mfg’ing, RO units, steam sterilization, EtOH sterilization, endotoxin removal, viral clearance, model virus studies, etc
Good Distribution Practices (GDP) Good Cold Chain Practices (GCCPs) Three main components of GDPs Good Import Practices (GIPs) Distribution Control Systems (DCS) GDP
Good Distribution Practices (GDP) RF TT, ISS Qualification, “import/Export ” Issues, returns, restock, Reverse Logistics Complaint mgt, Quality Agreements Good Cold Chain Practices (GCCPs) C-TPAT, TSA (CCFS/CCSP) Rules of Origin (COO), 10+2 (ocean transport), Trusted importer program GTIN, TnT, ePedigree (RFID), Lot number vs. 1-6-3-3, Serialization Mfg’ing/MA vs. Dist Control Good Import Practices (GIPs) Distribution Control Systems (DCS) GDP FEI rule changes Beyond Our Boarders, FDA Green lane, Import optimization (AOCC), RF enabled info Flow and “supplier supplier” information, Lacey Amendment, etc Congress (Dingle amendment, Kennedy Amendment, etc) And Other Gov’t initiatives
What do we Validate? • Mixers, granulators, mills, grinders, etc • Fluid Bed Dryers (FBDers), RO units, UF units, etc • Sterilizers, Ovens • Software (SQA, SIQ, SOQ, etc) • Manufacturing process of bulk APIs • Manufacturing process of finished goods • Shipment process of finished goods • HVAC units, clean rooms (class 100 hoods), etc • Controlled temperature warehouses • Refrigerated trucks (as part of the E/U/F validation program)
So how do we (should we) “validate” a reefer truck? • Big “V” and little “v”
What do we Validate? Refrigerated trucks are nomore complex • Insulated Trailer • Insulating capacity • Refrigeration unit • Cooling / Heating efficiently • Air flow efficiency All trailers (Class A, B, C) are all validated the same
Requirements - CFR Trailer Qualification Title 7: Agriculture – Can be used for your DQ, IQ, OQ • Chapter XXXIII—Office of Transportation, Department of Agriculture • PART 3300_ATP means the Agreement on the International Carriage of Perishable Foodstuffs and on the Special Equipment to be Used for Such Carriage (ATP), • Sec. 3300.61 Testing and verification requirements. • Sec. 3300.64 “the effective refrigerating capacity, W, in watts, of the appliance at an outside temperature of +30°C and the inside temperature for the class of equipment for which certification is sought”
Requirements – Industry Standards Industrial Standardization… • is the process of establishing agreement on uniform identifications for definite characteristics of quality, design, performance, quantity, service, etc. • sets acceptance criteria to meet requirements • maintains process controls and establishes testing methods • For reefer trucks the standard is already in place • So no need to repeat the DQ, IQ, OQ • As part of your quality agreement – make sure your TSP know this AND has acceptable maintaiance
Validation – The Steps • FDA’s Center for Drug Evaluation & Research (CDER) General Principles of Process Validation (big “V”): • The little “v” componensts of the big “V” • Design Qualification (DQ) • Installation Qualification (IQ) • Operational Qualification (OQ) • Performance Qualification (PQ) • Process Validation (PV) for the “process”
Validation – Installation Qualification (IQ) Insures that the system/equipment and its components are installed correctly and to the original manufacturer’s specifications • Vendor’s Data Sheet or Specification required: • Insulating specification or data sheet for the trailer • Refrigeration and heating system specification or data sheet for the trailer HVAC on wheels
Validation – Operational Qualification (OQ) Tests are performed on the critical parameters of the system/process. These are usually the independent and/or manipulated variables associated with the system/equipment • ATP testing meets OQ requirements: • A trailer’s insulating capacity • A trailer refrigeration / heating system must have sufficient capacity to remove and add heat generated by: • Residual heat from the air inside the trailer • Exterior heat conducted through the floor, walls and ceiling • Infiltration heat from outside air through small holes, cracks and seals • A trailer air circulation system must have sufficient air flow (VOLUME AND VELOCITY) to carry the heat of the trailer to the refrigeration unit where it can be removed.
Validation – Performance Qualification (PQ) This phase tests the ability of the process to perform over long periods of time within tolerance deemed acceptable. • Testing Actual shipments • Run in triplicate • Next steps Post PQ: Periodic Monitoring
Reefer Validation – History • What’s been done: • It was suggested that a staggered (wall loading) loading pattern was safer AND would adequately cool • That’s was wrong • Why? Blocked airflow
Data Review • Actual PQ data review
Ambient Temps Week of 7-9-07 Chicago Ambient Temperatures Somerset Ambient Temperatures Air temperature
All Monitors 7-9-07 Shipment Truck surface temperature Next to wall Next to ice bricks • Maximum load of 4 ½ product pallets plus Commodities • Loaded with the Off-set Wall loading pattern
Current Monitor Locations – based off previous Reefer truck mapping Long “cool down” time Next to wall, first pallet in Blue Line – Pallet A driver side Green Line – Pallet B facing back doors Red Line – Pallet V, last pallet facing doors
Monitors on outsides of pallets Long “cool down” Wide “profile” Monitor next to ice bricks, Walls, and on the top of commodity pallets not included. Warmest location – Pallet D up against the wall Coldest location – Last pallet facing the back doors
External Monitors – Stationary Truck ExternalSurface temp > Ambient air temp 115 °F 40 °C Air cooling effect Maximum air temperature was 92 °F (33 °C) Blue Line – Back door of trailer Green Line – Driver side Trailer wall Red Line – Passenger side Trailer wall
Monitors on Product Pallets – Wall Loading Pallet D – Passenger side (against the wall) Pallet E – next to the ice bricks Wall loading “blocks” airflow causing long cool down times and variable profile. Not a flat line.
Monitors on Commodity Pallets No heat load/sink, therefore, does not effect temperature, BUT loading pattern is still critical Ambient corrugate doesn’t effect profile
Internal on the product pallets – Wall loading Wide “Product” temperature profile and long cool down Pallet A took 6.5 hours to get within spec. Blue Line – Pallet A Green Line – Pallet B Red Line – Pallet C Yellow Line – Pallet D
Pallet A Monitors – Next to driver side wall Bad airflow, therefore, > 8 °C Per ASHRAE – airflow is more critical than temperature Blue Line – Driver side(against the wall) Red Line – internal to the pallet Green Line – Middle between rows of pallets Yellow Line – Top of pallet
Monitors on the inside of the trailer walls (6 ft high) Pallet height was variable from 5 Ft to 7 Ft Above 8 °C for 3.5 hours. Longer to achieve acceptable temperature – not optimal
Monitors on pallets up against the walls – Wall Loading Wall Loading blocks airflow Highest to Lowest Temperature (Maximum Delta of 8.5 °C) Green Line – Pallet D Blue Line – Pallet A Red Line – Pallet E Yellow Line – Pallet L Light Blue Line – Pallet U
TempTales on pallets away from the walls Still a long time to cool vs centerline loading (and not a flat line) Highest to Lowest Temperature (Maximum Delta of 2.2 °C) Green Line – Pallet C Red Line – Pallet K Blue Line – Pallet B Yellow Line – Pallet V
Middle Monitors between Pallets – stayed above temp as long as wall pallets 6 hours above 8 °C Next to ice bricks Highest to Lowest Temperature (Maximum Delta of 21°C) Red Line – Pallet U Green Line - Pallet E (next to icebricks)
What Should be Done • Centerline Loading • Shows that loading pattern is most critical and that set point can be maintained with proper loading pattern
Ambient Temps Week of 7-16-07 Chicago Ambient Temperatures Somerset Ambient Temperatures
All internal monitors - Centerline Quick cool down and excellent control (low variability) Looks like a cold room
External Monitors – Truck surface Blue Line – Back door of trailer Green Line – Driver side Trailer wall Red Line – Passenger side Trailer wall
Monitors on Product Pallets Good airflow – based off loading pattern, no hot/cold spots, therefore, monitor location not critical
Internal on the product pallet Monitor location not critical Blue Line – Pallet A Green Line – Pallet B
Monitors on the inside of the trailer walls External wall temp ~ 100 °F, R value is adequate to insulate vs. conduction
Middle Monitor between Pallets Flat line
