VAH list
VAH = Association for Applied Hygiene
(previously DGHM = German Society for Hygiene and Microbiology)
The VAH/DGHM list describes the procedures required for routine prophylactic disinfec-
tion, and in particular for the prevention of infection in hospitals, doctors' offices, public
areas and other areas where there may be the risk of infection spreading.
With respect to an officially directed disinfection, § 18 of the Infection Protection Act is in-
voked.
Special validated procedures and machines are to be used for surgical textiles as medical
devices. The procedures and machines listed here are not medical devices.
Avoidance of contamination or recontamination
Disinfect your hands before using the machine.
Use clean/disinfected transport containers.
Dispense cleaning agents and disinfectants in accordance with instructions.
Observe regulations regarding the wearing of protective clothing.
Ensure that water is bacteria-free when using water from water treatment units.
Clean detergent drawers, detergent compartments and siphons before use.
Cleaning dispensing drawers and siphons
The detergent drawer is subject to constant moisture. It needs to be cleaned regularly to
prevent the build-up of water-borne bacteria.
Clean the detergent drawer, detergent compartments and siphon thoroughly with hot wa-
ter as required to remove detergent residues and encrustation.
It is the supervisor's responsibility to ensure that the standard of disinfection in thermal as
well as chemo thermal procedures is maintained (from the list, in accordance with § 18
German infection control legislation) by carrying out suitable validation tests. The proced-
ures should be checked at regular intervals, thermoelectrically by means of loggers or bac-
teriologically using bio-indicators. The supervisor must pay particular attention to ob-
serving the process parameters temperature and, in the case of chemo-thermal pro-
grammes, the concentration. Disinfection programmes must not be interrupted, as this
can have a limiting effect on the disinfection result.
Water connection for variants with reduced heater rating (RH)
The appliance should be connected to cold and hot water supplies. A minimum hot water
temperature of 80 °C is recommended in order to use all programmes. Lower temperatures
may result in longer programme running times or cause programmes to be interrupted. Wa-
ter inlet temperatures below 60 °C are not permitted, as they can lead to significantly
longer programme running times.
Water connection for variants with external heating (EH)
The appliance should be connected to cold and hot water supplies. A minimum hot water
temperature of 80 °C is recommended. The use of disinfection programmes is not possible
due to the absence of additional heating. The permissible wash temperatures are determ-
ined by the inlet temperature.
