Study Notes
Cross Contamination Minimization
- Personnel procedures enhance technical awareness and skills.
- Proper premises layout and area classification are essential for contamination control.
- Closed production systems limit movement of personnel and materials.
- Validated cleaning procedures ensure effective sanitation.
- Protect product with adequate preventive measures.
- Correct HVAC design ensures appropriate air pressure and distribution.
Contaminant Removal Methods
- Efficient filtration of supply air is critical for cleanliness.
- Diluting contaminants through adequate air supply helps maintain air quality.
Clean Room Definition
- A clean room controls particulate and bacterial contamination to prescribed levels.
Controlled Facility Parameters
- Key factors include controlling temperature, humidity, air cleanliness, room pressure, air movement, and lighting.
Influencing Factors for Protection Levels
- Particle count and microorganisms in the air affect contamination risk.
- The number of air changes, air velocity, flow patterns, and filter effectiveness all influence air quality.
- Maintaining air pressure differentials is essential for preventing contamination.
Proper Hygiene Practices
- Dress code includes clean uniforms, closed footwear, hair restraints, and no jewelry.
- Prohibited habits: eating, drinking, smoking, and other personal activities in clean areas.
- Regular handwashing is required before and after specific activities like handling raw ingredients or after using the restroom.
Microbial Contamination Sources
- Airborne dust and personnel are primary sources of microbial contamination, with significant bacteria release per person actions.
- Sneezing can release up to 1 million bacteria, emphasizing the need for contamination controls.
Cleaning Procedures
- Regular cleaning and housekeeping of all facility areas are mandatory.
- Risk factors must be assessed based on severity and likelihood of patient impact.
Risk Reduction Measures
- Risk control strategies include prevention (eliminating hazards) and protection (reducing severity/impact).
- Techniques involve increasing detection methods, slowing machine rates, or implementing maintenance protocols.
Importance of Risk Management (QRM)
- Poor decisions cannot be corrected solely through QRM; a multi-disciplinary approach is preferred.
- Documentation of decision-making processes is crucial.
Definitions of Terms
- Contamination: Introduction of unwanted impurities during various production stages.
- Cross Contamination: Unintentional mixing of products or materials during manufacturing.
- Contaminant: Any entity adverse to product integrity.
Prevention of Cross Contamination
- Ensure proper design and maintenance of air systems and dust extraction.
- Regularly empty and clean bins, and promptly address spills.
Cleaning Validation
- Documented evidence is crucial to assure the effectiveness of cleaning procedures in the pharmaceutical industry.
Facility and Equipment Cleaning Needs
- Facilities should be appropriately sized, have easy-clean surfaces, and maintain adequate environmental conditions.
- Equipment must feature smooth, inert surfaces, and be manageable for cleaning.
Manufacturing Process Considerations
- Facilities should be dedicated to single formulations, with proper cleaning checks between batches.
Contamination Mitigation Strategies
- Ensure personnel wear cleanroom garments.
- Utilize HEPA filters to enhance ventilation quality.
- Maintain good housekeeping and the facility's structural integrity to prevent contamination.
