Day 1 : Contamination Risk Assessment in Pharmaceutical Cleanrooms
Cleanrooms are highly controlled environments where the air quality is monitored to ensure the extreme standards of cleanliness required for the manufacture of pharmaceutical, electronic and healthcare goods. Contamination controls is the primary consideration in cleanroom design, especially in the pharmaceutical facilities where contamination risk is concerned. However, contamination risk levels differ in aseptic, and non-sterile and terminally sterilized products. Within the non-sterile products risk levels vary per mode of administration. In terminally sterilized products, contamination for a terminally sterilized medical device may differ from a terminally sterilized drug product. Contamination risk in a non-sterile drug product may be different for a healthy patient as compared to an immunocompromised patient or children.
Contamination risk assessment initially begins with understanding the nature of a product, release specifications and which organisms are objectionable. In some medical device manufacturing, particulate contamination could also be objectionable because of the electronics involved.
The manufacturing facility is designed to mitigate and reduce contamination risks. Facility controls vary depending upon final product requirements. Contamination may also result due to inadequate cleanroom/RABs/Isolator/design and maintenance. Similarly, if a risk based approach is not adopted right from the beginning, contamination risks can occur due to utilities, raw materials, excipients, process and also inadequate testing.
With ICH Q9, Q10, ISO and EU all aligned on a risk based approach; it is time to explore performing a real risk assessment to control contamination in your product.
In this seminar (Day 1), you will understand the evolution of contamination control technology and will experience common misunderstood design/integration mistakes in cleanrooms and barrier/isolation technology. The limitation-of-Risk (LR) method which can be used as an engineering tool in risk assessment for the identification, minimization and evaluation of potential airborne risks, and for the identification of adequate monitoring points will be discussed. Besides theoretical point of view, there will be case studies and investigative methods for finding contamination sources.
Day 2 : Air Flow Visualization techniques and technology: How to avoid common mistakes and misunderstandings related to smoke studies.
Understanding airflow patterns in cleanrooms and controlled environments is an important aspect in contamination control. Personnel, equipment and material flow can influence airflow and affect contamination levels in even the most well designed cleanrooms. Air flow visualization studies, sometimes referred to as smoke studies are useful in providing a visual representation of air flow in cleanrooms. These tests can also be useful in troubleshooting cleanroom contamination issues from undetected air patterns that limit a cleanrooms ability to provide adequate contamination control.
Though considered an optional test as listed in ISO 14644-3, Airflow Direction Test and Visualization is an expected test by pharmaceutical inspection authorities.
 The US FDA “Guidance for Industry Sterile Drug Products Produced by Aseptic Processing Current Good Manufacturing Practice” “Air pattern analysis should be conducted at the critical area to demonstrate unidirectional airflow and sweeping action over and away from the product under dynamic conditions. The studies should be well documented with written conclusions, and include evaluation of the impact of aseptic manipulations (e.g., interventions) and equipment design.”
 GMP Annex 1 States that “air-flow patterns are to be demonstrated that they do not distribute particles from sources including, personnel, operations or machines into zones of higher product risk.”
 USP 1116 suggests the use of Airflow Visualization techniques to evaluate air flow patterns under dynamic conditions and must include the evaluation of personnel movement for all aseptic manipulations.
The type of equipment and material used in creating the airflow visualization vapor or smoke is as important as the techniques used. As these test require the use of Tracer Particles generated and released into the cleanroom, clean air devices and areas adjacent to these areas, care should be taken in choosing the desired size and material of these Tracer Particles. The Tracer Particles should be of suitable size and volume as to visually represent the air moving through the cleanroom or clean space being tested.
Improperly conducted air flow visualization studies or the use of equipment that may not be suitable for conducting these studies may lead to a misleading conclusion related to airflow in critical areas. As the various pharmaceutical inspection authorities expect these studies to be conducted under dynamic conditions, simulations of actual processing operations it is important to understand the complexities related to doing dynamic smoke studies.
This seminar (Day 2) will discuss the various methods and techniques of air flow visualization as well as provide examples of improperly tested facilities including FDA 483 Observations and warning letters related to airflow visualization.
