2023 with complete solution
Define Cleaning
"the removal of contamination from an item to the extent necessary for further
processing or for the intended use"
Define Decontamination
"the use of physical or chemical means to remove, inactivate, or destroy BBP on a
surface or item to the point where they are no longer capable of transmitting infectious
particles and the surface or item is rendered safe for handling, use, or disposal"
