2. What is Sterilization? Sterilization is the process of destroying or removing all microorganisms, including bacterial spores, to achieve a sterile state. It is essential for preventing infections in medical, pharmaceutical, and laboratory environments.

3. Why Sterilization is Important Sterilization ensures safety in medical procedures by eliminating harmful microorganisms and preventing the transmission of infectious diseases. It reduces healthcare-associated infections and maintains sterile environments.

4. Types of Sterilization Methods Sterilization methods include physical methods like heat (dry and moist), filtration, and radiation, chemical methods such as ethylene oxide, and mechanical methods like filtration for air and liquids.

5. Dry Heat Sterilization Dry heat sterilization uses high temperatures (150°C–170°C) to kill microorganisms through oxidation. It is commonly used for heat-resistant items like glassware and metal instruments.

6. Moist Heat Sterilization (Autoclaving) Moist heat sterilization uses steam under pressure to denature proteins and kill microorganisms. Autoclaving, the most common method, is effective for sterilizing surgical instruments, textiles, and liquids.

7. Radiation Sterilization Radiation sterilization uses ionizing or non-ionizing radiation to kill microorganisms. Gamma radiation is used for medical devices, while UV light is used for surface and air sterilization in hospitals.

8. Chemical Sterilization Chemical sterilization involves using agents like ethylene oxide and hydrogen peroxide. Ethylene oxide is effective for heat-sensitive devices, while hydrogen peroxide is a faster, safer alternative.

9. Filtration Sterilization Filtration sterilization is used to remove microorganisms from liquids and gases that are heat-sensitive. It is commonly used in pharmaceutical industries and in sterile environments like operating rooms.

10. Gas Sterilization Gas sterilization, including methods like ethylene oxide and hydrogen peroxide gas plasma, is used for delicate equipment. These methods allow low-temperature sterilization for moisture-sensitive materials.

11. Monitoring Sterilization Processes Sterilization monitoring is crucial for ensuring process effectiveness. Biological indicators use spores to verify sterilization, while chemical and mechanical methods track sterilization parameters.
