8.3. Mechanical cleaning and disinfection
When selecting the washer-disinfector (WD), the following points must be observed:
■
The cleaning and disinfection device must have a fundamentally tested effectiveness
(e.g., CE marking in accordance with DIN EN ISO 15883).
■
Basic suitability of the program for instruments as well as sufficient rinsing steps
in the program.
■
Post-rinse exclusively with sterile or low-contaminated water (max. 10 germs/ml,
max. 0.25 endotoxin units/ml, for example purified or highly purified water)
■
Exclusive use of filtered air (oil-free, low contamination with microorganisms
and particles) for drying.
■
Regular maintenance and inspection/calibration of the WD.
Consider the following points when selecting the cleaning agent:
■
Basic suitability for cleaning instruments made of metal or plastic.
■
Additional application: if thermal disinfection is not used - of a suitable
disinfectant with tested efficacy (e.g., approval/registration with/from
VAH/DGHM or FDA/EPA or CE marking), compatible with the used
cleaning agent.
■
Compatibility of the cleaning agents used with the components. The instructions of the
manufacturers of the cleaning agents regarding concentration, temperature, immersion
time and rinsing must be observed.
