Control of airborne particulate materials with HEPA filters allows the construction of clean rooms and isolation rooms for quarantine, as well as specialized diagnostic/research laboratories. If performed at this location, confirm that the sterilization process, associated environmental and contamination controls, and monitoring and acceptance procedures maintained by the shop floor are the most current approved revision contained within the Device Master Record (DMR). Methods of Sterilization . . The effects of heat sterilization occur more rapidly in a fully hydrated state, as it requires a lower heat input, with low temperature and less time, under high humidity conditions where the denaturation and hydrolysis reactions are predominant, rather than in the dry state where oxidative changes take place. At 400-600 MPa, proteins are easily denatured, and cell morphology is altered, and ribosomes are destroyed. When conducting a complete sterilization process validation study assessment, the items included in the narrative note under Objective 4 of the Production and Process Controls chapter of this Handbook apply. 15-d) 160 degrees Celcius for 45 mins.

The establishment of process parameters and tolerances; 3. With ionizing radiation, microbial resistance decreases with the presence of moisture or dissolved oxygen (as a result of increased free radical production) and also with elevated temperatures. In this method, the microorganisms are killed by coagulating their proteins, and this method is much more effective than dry heat sterilization where microbes are killed through oxidation. On average, the microorganisms may range from 10-2,000/m 3 while the suspended particles may be 20-100,00/ m 3. For example, lipid emulsions undergo degradation at 121 C but can withstand sterilization at 115 C. An important linkage to consider at this point is Management Responsibility (820.25 Personnel). Filtration under pressure is generally considered most suitable, as filling at high flow rates directly into the final containers is possible without problems of foaming, solvent evaporation, or air leaks.
