What is the level of decontamination that reduces the amount of germs but doesn’t kill microbes?

Eliminates most pathogens but not necessarily all types of microbes. Disinfection reduces the level of microbial contamination. Chemical disinfection does not kill spores, unlike chemical sterilization. Some common laboratory disinfectants include freshly prepared10% bleach and 70% ethanol.

What are the four methods of decontamination?

There are 4 main categories of physical and chemical means of decontamination: (1) heat; (2) liquid disinfection; (3) vapors and gases; and (4) radiation.

What is the last step in basic six step decontamination line?

What follows is an example of a basic six-step decontamination line. As stated earlier, each step should be separated physically to prevent cross contamination and should be arranged in order of decreasing contamination. Station 3 – Air tank change (NOTE: this is the last step if worker returns to Hot Zone.)

Which type of microbe is the most difficult to kill?

Endospores are considered the most resistant structure of microbes. They are resistant to most agents that would normally kill the vegetative cells they formed from. Mycobacterial infections are notoriously difficult to treat. Protozoa cysts are quite hard to eliminate too.

Does sterilization kill virus?

Sterilization refers to any process that removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.)
