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
disinfection, 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
invoked.
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 washing and disinfecting agents 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 dispensing drawers, detergent compartments and siphons before use.

Cleaning dispensing drawers and siphons

The detergent dispensing drawer is subject to constant moisture. It needs to be cleaned
regularly to prevent the build-up of water-borne bacteria.
Clean the detergent dispensing drawer, detergent compartments and siphon thoroughly

with hot water as required to remove detergent residues and encrustation.
It is the operator's responsibility to ensure that the standard of disinfection in thermal as
well as chemo-thermal procedures is maintained (in accordance with local and national
health and safety regulations) by carrying out suitable validation tests. The procedures
should be checked periodically, thermoelectrically by means of loggers or
bacteriologically using bio-indicators. The operator must pay particular attention to
observing the process parameters temperature and, in the case of chemo-thermal
programmes, the concentration. Disinfection programmes must not be interrupted, as this
can have a limiting effect on the disinfection result.
