Recontamination

Verification
testing
Carry out a visual check before starting every program:
– Is everything correctly loaded/connected for cleaning?
– Was the recommended loading template followed?
– Can the lumen/narrow sections of hollow items be accessed by the
wash fluid?
– Are the spray arms clean and do they rotate freely?
– Are the filters clean?
Remove any coarse soiling and clean them if necessary.
– Are the removable modules, injector nozzles, irrigation sleeves and
other rinsing fittings securely connected?
– Are the baskets and modules or mobile units correctly connected to
the water supply and are the water connectors undamaged?
– Are all process chemical containers sufficiently filled?
The following must be checked at the end of every program:
– Carry out a visual check of the load for cleanliness.
– Check that all hollow items are still securely located on their injector
nozzles.
 Any hollow items that have become disconnected from their
fittings during reprocessing must be re-processed.
– Check that the lumen of hollow items are free of obstruction.
– Check that injector nozzles and connectors are securely held in
position in the baskets or inserts.
Take appropriate measures to prevent recontamination of processed
items, e.g.:
Wear clean gloves when removing the wash load.

Remove the entire wash load from the carriers before reloading

them.
For verification of the cleaning process, periodic testing as outlined in
current best practices documents such as AAMI ST79 is highly
recommended. While Miele washers automatically monitor critical
parameters such as time, temperature and dispensing, periodic
verification to ensure proper soil removal should be part of your
quality and safety program.
Miele also offers process documentation to support your periodic
verification.
