Good PracticesGood Practices
Design of Premises
Design
Walls, floors, ceilings, ledges, drains, air supply, dust extraction
Prevention of build-up of dirt and dust to avoid unnecessary risks of contamination
Cleaning programme, appropriate cleaning, cleaning records
Effective cleaning and disinfection
choice of materials and chemicals, validation
Drains – prevent backflow
Protection from insects, birds, vermin and weather
from receipt of raw materials to dispatch of released product
12.2, 12.3, 12.7, 12.9, 12.29
Module 13 | Slide 5 of 30 January 2006
Basic Principles of GMPBasic Principles of GMP
Walls, floors, ceilings – smooth and easy to clean
No ledges or areas where dust can accumulate
Prevention of build-up of dirt and dust to avoid unnecessary risks of contamination
Module 13 | Slide 6 of 30 January 2006
16.10 - 11
Good PracticesGood Practices
Avoidance of Cross-Contamination I
Special precautions should be taken to prevent generation and dissemination of dust
Proper air control – supply and extraction, suitable quality
Due to uncontrolled release of: dust, gas, particles, vapours, sprays, organisms, residue, insects

Avoidance of Cross-Contamination II
Dedicated and self-contained areas for: Live vaccines Live bacterial preparations Certain other biological materials Penicillin products

Good PracticesGood Practices
Avoidance of Cross-Contamination III
Campaign production:
Separation in time
Followed by appropriate cleaning
Validated cleaning procedure

16.12 (c and d)
Good PracticesGood Practices
Avoidance of Cross-Contamination IV
Ventilation systems and airlocks Appropriately designed ventilation system with air supply and
extraction systems
Supply or incoming air should be filtered
Recirculation of air versus 100% fresh air supply
Proper airflow patterns
Pressure differentials
Appropriately designed airlocks

16.12(e)
Good PracticesGood Practices
Avoidance of Cross-Contamination V
Clothing
Protection of operator and product
Highly potent products or those of particular risk - need for special protective clothing
Personnel should not move between areas producing different products
Garments need to be cleaned
Module 13 | Slide 11 of 30 January 2006
16.12(f, h and i)
Good PracticesGood Practices
Avoidance of Cross-Contamination VI
Cleaning and decontamination
Procedure for removing soil and dirt
Remove all cleaning chemical residues or disinfectant residues
Remove and/or reduce micro-organisms
Validated (known effectiveness of the procedure)
Use cleanliness status labels
Test for residues
Module 13 | Slide 12 of 30 January 2006
16.12(g)
Good PracticesGood Practices
Avoidance of Cross-Contamination -VII
Closed processing systems
For example: totally enclosed water purification systems
Tanks fitted with appropriate filtration - without removable lids
Present special cleaning difficulties, sometimes use
clean-in-place (CIP)
Module 13 | Slide 13 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – I
Work-flow
designed to avoid potential contamination
Access
to production areas restricted to authorized personnel
direct operators, QC staff, warehouse staff, maintenance personnel, cleaners
the more critical the area - fewer number of persons there
Module 13 | Slide 14 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – II
Simultaneous operations
not permissible to process different products in different areas with a common ventilation system
permissible to carry out secondary packaging activities for different products within a packing hall with adequate physical separation
Module 13 | Slide 15 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – III
Area clearance checks
Process of checking all materials and documentation from the previous batch
removed all plant and equipment thoroughly cleaned and appropriate
status labelling checklist useful
Module 13 | Slide 16 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – IV
Area clearance checks
The area clearance check should be carried out by two people
between batches of same product, acceptable for both checks to be carried out by production personnel
for product changeover, second check carried out by QC staff
all checks carried out in accordance with written SOP and results recorded on the batch documentation.
Module 13 | Slide 17 of 30 January 2006
Basic Principles of GMPBasic Principles of GMP
Line opening:
Includes checks on materials and components
Batch number
Expiry date
Printed packaging material including cartons, leaflets, foil . . .
Module 13 | Slide 18 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – V
Cleaning and cleaning validation
degree of cleaning depends on whether consecutive batches are of same or different product
Check cleaning agent is fully removed
If possible hot water alone used for cleaning
all cleaning and disinfecting solutions carefully prepared and expiry dated
Final rinse with purified water, or water for injection (for sterile products)
Full records kept
Module 13 | Slide 19 of 30 January 2006
Good PracticesGood Practices
Production Operations – Sanitation – VI
Water systems
Water - major constituent of most products
SOP for cleaning and sanitization of the water purification system should include distribution pipework
Validation and removal of disinfectant before reuse

Production Operations – Sanitation – VII
Maintenance and repair
activities inevitable in manufacturing area
Should present no risk to product
Whenever possible, all planned maintenance outside normal operating hours
Emergency work in working area followed by thorough clean down and disinfection before manufacturing recommences
Area clearance by QC

Good Practices in Quality Control (QC)
Complete module on Quality Control Laboratories. This section only reflects some aspects of good practices in QC labs
Each manufacturer should have a QC Department
Independence from production and other departments is fundamental
Under the authority of an appropriately qualified and experienced person with one or several control laboratories at his or her disposal
