Study Notes
Production Areas
- Aim to minimize risks of serious medical hazards through cross-contamination prevention by using isolated and self-contained facilities for sensitive pharmaceutical products.
- Facilities must be logically connected and designed according to the operational sequence and required cleanliness levels.
- Interior surfaces like walls, floors, and ceilings should be smooth, crack-free, and easy to clean to avoid particle shedding.
- Utilities such as pipework and ventilation points must be designed to avoid recesses for easy maintenance and cleaning access.
Weighing Areas
- Weighing of starting materials must occur in designated areas with dust control, which can be part of either storage or production zones.
- Laminar flow workplaces should be utilized for weighing large quantities under cleanroom conditions.
Quality Control Areas
- Quality Control (QC) should be separate from production areas to prevent mix-ups and cross-contamination.
- Sufficient space is essential for suitable storage of samples, reference standards, solvents, and records.
- QC areas require non-absorbent, skid-proof flooring materials resistant to chemicals, and construction materials should minimize joints for effective cleaning.
- Instruments may need a separate room to protect from interference and environmental factors.
Ancillary Areas
- Rest, refreshment, and meeting rooms must be isolated from manufacturing and control areas.
- Facilities for changing clothes and personal hygiene should be easily accessible without direct connection to production areas.
- Maintenance workshops should ideally be separated from production, and tools should be stored in designated areas.
- Animal housing should be well isolated, with separate entrances and air-handling systems.
Heating, Ventilation, and Air Conditioning (HVAC)
- HVAC system design directly impacts architectural layout regarding airlocks, clean areas, and cross-contamination controls.
- Contamination prevention is a critical design consideration for HVAC systems.
- Temperature, humidity, and ventilation must be suitable to avoid affecting product quality during manufacture and storage.
- HVAC efficiency guidelines are based on the type of product being manufactured (sterile vs. non-sterile).
Cleanroom Characteristics
- Cleanrooms are designed to prevent external contamination, with people and processes identified as primary sources of contamination.
- Establish cleanroom specifications by addressing contamination sources, required particle size filtration, and necessary air circulation for contaminant removal.
- Areas are classified into levels of protection based on cleanliness and contamination control.
HVAC System Parameters
- Key parameters for HVAC qualification include temperature, humidity, air quantities, airflow patterns, and filter performance.
- HEPA filters play a crucial role in preventing contamination through high-efficiency filtration.
Conclusion
- Proper understanding and implementation of design principles for production, quality control areas, and HVAC systems are essential for maintaining quality assurance and compliance in pharmaceutical manufacturing settings.
