Tech in Surgery Prep / Unit 2 TSC 044 short lesson, about 20 seconds
Cleaning, Disinfecting, Sterilizing
Captions available
The idea
Three levels of decontamination rise in order: cleaning, disinfection and sterilization.
In practice
Cleaning removes visible soil; disinfection kills most microbes on objects but not all spores; sterilization destroys all microorganisms, including spores.
Where people slip
Every item must be cleaned first; soil left on an instrument can shield microbes from disinfection or sterilization.
