Disinfection - general information

What is disinfection?

Deactivation and reduction in number of pathogens transmitting diseases to such an
extent that the transmission of diseases and infection is no longer to be anticipated.

Thermal disinfection

Thermal disinfection is carried out by the action of a defined temperature over a holding
time. In the list, according to § 18 IFSG, this is 90 °C over 10 min. or 85 °C over 15 min.
With a suds ratio of 1 - 4 to 1 - 5 with the activity range AB.
The thermal disinfection is independent of the detergent used, which does not have to be
classified.

Chemo-thermal disinfection

Chemo-thermal disinfection differs from thermal disinfection by a lower suds temperature
during the disinfection phase. A compensation for the low temperature is ensured by the
correspondingly listed washing and disinfecting components.
Important is that these products are used exactly according to listing. The suds
temperature, the suds ratio and the time of dosing must be strictly adhered to.
For disinfection wash programmes there are two lists in which the necessary process
parameters with regard to washing and disinfecting agents are listed.

RKI list (Robert Koch Institute)

Describes procedures for disinfection according to § 18 Infection Protection Act. These
processes are only required when a health authority prescribes the use of disinfection in
the event of the outbreak of an epidemic relating to a notifiable, transferable disease where
there is a risk of items being contaminated. The RKI lists thermal disinfection processes as
well as chemo-thermal methods.

Disinfection process according to areas of impact

Disinfection procedure is divided into areas of impact A, B and C.
– Area of impact A:
Suitable for the destruction of vegetative bacteria, including mycobacteria, fungus and
fungal spores.
– Area of impact B:
Suitable for deactivating viruses.
– Area of impact C:
Suitable for killing anthrax spores.
In the event of officially directed disinfection, the first drainage of wash liquid may not be
discharged until after disinfection has been carried out.
