The document discusses the design of aseptic areas for sterile product production. It outlines several key aspects of aseptic area design including: - Dividing the production area into clean-up, compounding, aseptic, quarantine, and packaging areas. - Using smooth, cleanable materials like stainless steel, glass or epoxy paint for floors, walls and ceilings. - Fitting doors and windows flush to walls and maintaining positive air pressure and airflow. - Supplying high-efficiency filtered air through HEPA filters and laminar airflow benches. - Controlling airflow patterns to avoid particle generation and maintaining cleanroom classifications.
