Decontamination Flashcards
In a Washer Disinfector the standard disinfection temperature banding is 90-95 degrees for the disinfection stage. What is the minimum hold time for this stage.
1 minute
What is the standard sterilisation temperature band for non temperature sensitive equipment
134-137 degrees
Simon hasn’t been doing decontamination very long. Today there are some forceps that require manually washing before further processing. He can’t really remember the correct volume of chemical to dose, his best bet would be to check the side of the chemical container
True
Dilution is essential for the efficacy of the chemical
We should follow the manufacturers recommendations when dosing chemicals to make sure we add the right volume for the correct level of dilation
On the life cycle of instruments diagram (circular diagram), what stage follows cleaning
Disinfection
What is the standard sterilisation stage hold time when sterilising non temperature sensitive equipment and instrumentation

What is the optimal temperature of the water in the sink if you are having to manually wash
30-35 degrees

Channeled or lumened instruments
Instruments are sterile at the point of use from which steriliser and why
From a type B steriliser and this is because they are wrapped
