    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.
