Presentation transcript:

Objectives: Ch. 9 Distinguish between the concepts of decontamination, sanitization, and sterilization as well as “cidel” vs “static” effects. Understand situations requiring decontamination and the practical concerns Identify the common heat method practices and usefulness in controlling microbes Explain the nature and usefulness of ionizing and non-ionizing radiation Explain the usefulness and applications of filtration in controlling microbes Explain the differences between disinfectants, antiseptics, and sanitizers Describe the ways in which chemical control agents work to kill microbes and the traits which make a chemical a good disinfectant/antiseptic
