Answers
Explanation:
Ionizing Radiation
Sterilization by ionizing radiation, primarily by cobalt 60 gamma rays or electron accelerators, is a low-temperature sterilization method that has been used for a number of medical products (e.g., tissue for transplantation, pharmaceuticals, medical devices).
Dry-Heat Sterilizers
This method should be used only for materials that might be damaged by moist heat or that are impenetrable to moist heat (e.g., powders, petroleum products, sharp instruments).
Liquid Chemicals
Several FDA-cleared liquid chemical sterilants include indications for sterilization of medical devices (Tables 4 and 5)69. The indicated contact times range from 3 hours to 12 hours.
Performic Acid
Performic acid is a fast-acting sporicide that was incorporated into an automated endoscope reprocessing system400. Systems using performic acid are not currently FDA cleared.
Filtration
Although filtration is not a lethality-based process and is not an FDA-cleared sterilization method, this technology is used to remove bacteria from thermolabile pharmaceutical fluids that cannot be purified by any other means.
