Methods of Decontamination :
Choice depends on the type of material, level of decontamination essential and microorganisms involved.
Cleaning
Disinfection
Antiseptics
Sterilization
CLEANING:
Essential prerequisite.
Allows physical removal of native upshot and hence microorganisms.
Allows complete surface contact during decontamination procedure.
Requires trained staff.
DISINFECTION :
 go out destroy microorganisms but not bacterial spores.
Not of necessity kills all microbes present but reduces them to harmless levels.
Should only be employ if heat treatment is impractical or malign to the material.
STERILANT: chemical disinfectant that kills bact. spores ( usually takes long exposure time) called high Level Disinfection.




Outcome is affected by the
Presence of organic matter (Bioburden)
Type & Level of microbial contamination
Disinfection concentration
 characterisation time
 somatogenic structure of the object
Temperature & pH of the process
ANTISEPTICS :
Chemicals used to kill microbes on flake off or living tissue.
Must have effective germicide activity.
Must not be toxic to living tissues.
 sterilization :
Process of comlete destruction of all microbes, including bacterial spores.
Dry wake up :
Requires higher temp. for much longer periods to kill all microbes.
Exposure in an oven for 2 hr. at 170*C.
Generally used for glasswares.
-
Moist Heat :
Far more penetrating than change heat hence more effective for killing microbes.
 steam under pressure is used in an autoclave in this procedure.
Should be monitored using chemical and biological...If you want to get a full essay, order it on our website: Ordercustompaper.com
