Study Notes
Contamination
- What are the main concerns in a cleanroom? Protecting the produced product from microbial and particulate contamination.
- What is microbial contamination? The non-intended introduction of infectious substances like bacteria, viruses, fungi, etc.
Contamination
- Defined as the undesired introduction of impurities such as chemical, microbial, or foreign matter, into the production or storage process.
- Contamination types: Chemical, Microbial and Particulate.
Impact of Contamination
- Patient safety: Contaminated products can harm patients, especially those who are already ill.
- Product rejection and recall: Contamination can lead to product failure and costly recalls, damaging company image.
What are Contaminants?
- Products or substances other than the product manufactured.
- Contaminant examples:
- Foreign products
- Particulate matter
- Micro-organisms
- Endotoxins (degraded micro-organisms)
- Cross-contamination can be classified as contamination.
Preventing Contamination
- The use of properly designed and maintained clean rooms, including:
- Controlled access for personnel and materials.
- Sanitization of clean rooms.
- Sterilization of equipment and product.
- Aseptic technique: Proper gowning, controlled movements, and sterile handling.
Contamination Sources
- People: The major source of contamination, shedding particles, bacteria, and viruses.
- The environment: Particles in air, floors, and surfaces.
- Materials: Dust, chips, flakes, and debris.
- Equipment/Tools: Contaminated surfaces and residues.
- Water/Fluids: Introducing microbes.
- Cleaning: Inadequate cleaning can introduce contaminants.
- Product being manufactured: Cross-contamination.
Personnel
- The biggest source of contamination, shedding skin flakes, hair, and other particles.
- Mindset: Consciousness, attention to detail, self-motivation, and hygiene are crucial.
Conditions that can affect Cleanrooms
- Skin conditions: Skin cells, dermatitis, sunburn, dandruff.
- Respiratory conditions: Coughing, sneezing.
- Allergic conditions: Allergic reactions to materials used in the cleanroom.
People and Contamination
- Non-viable contamination: Dead skin cells (particulates)
- Viable contamination: Live micro-organisms
- Contamination spread: Coughing, sneezing, and itching exacerbate microbial contamination.
Environment
- Invisible dust particles (non-viable particulates), present in air and surfaces, can contaminate products.
Product
- Product dust: Contaminated dust particles.
- Other product materials: Silicon chips, quartz flakes, aluminum particles.
Cross-Contamination
- Definition: Contamination of raw materials, intermediates, or finished products during production, storage, or transport.
- Origin: Poorly designed or maintained air handling systems, inadequate procedures, insufficient cleaning.
Minimizing Cross-Contamination
- Personnel procedures: Proper gowning, hand hygiene.
- Adequate premises: Clean, well-maintained environment.
- Closed production systems: Preventing product exposure to the environment.
- Validated cleaning procedures: Effective and efficient cleaning.
- Levels of product protection: Protective barriers and packaging.
- Air pressure cascade: Maintain air pressure differentials to prevent airflow from contaminated areas to clean areas.
