drying
what are the principals of loading the washer disinfector
do not overload instrument carriers or overlap instruments
open instrument hinges and joints fully
use appropriate instrument carriers and trays for use in the WD
what features should an ultrasonic bath have
control of process variables like time/temp
lid with lock

how do you de-gas the ultrasonic
run the ultrasonic while filled with cleaning solution but no instruments for manufacturer specified time on start up and on refillings
how do you avoid instrument damage during manual cleaning
avoid wire brushes
remove instruments that have rust spots
do not use wire pot scourers
avoid contact with damaging chemicals
how do you dry instruments after ultrasonic cleaning or manual cleaning
use disposable low-linting towels to dry instruments
what do you do when you inspect instruments
inspect instruments for visible soiling
check to make sure they are in working order
dispose of damaged instruments
at what point do you lubricate handpieces/other hinge instruments
before sterilisation but after cleaning
what standards document should validation and testing follow for equipment
SHTMs
what type of steriliser is a vacuum steriliser
type B
what type of steriliser can wrapped instruments go into
type B
when are instruments sterilised
have been cleaned, inspected and undergone sterilisation unwrapped
when are instruments sterile
