Disinfection

general
information
What
is
disinfection?
r
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
mins.
or
85°C
over
15
mins.
With
a
load-to-liquor
ratio
of
1
-
4
to
1
-
5
with
the
activity
ränge
AB
(cf.
Section
on
‘
Disinfection
processes
according
to
activity
ränge').
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
in
terms
of
a
lower
liquor
temperature
during
the
disinfection
phase.
Compensation
for
the
low
temperature
is
ensured
through
the
use
of
listed
washing
and
disinfecting
components.
It
is
important
that
these
products
are
used
exactly
according
to
the
listings.
The
suds
temperature,
the
load-to-liquor
ratio
and
the
time
of
dispensing
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.
Requirements
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
list
describes
both
thermal
and
chemo-thermal
disinfection
processes.
Disinfection
process
according
to
areas
of
impact
Disinfection
procedure
differ
by
the
relevant
areas
of impact
A,
B
and
C.
-
Area
of
impact
A:
Suitable
for
the
destruction
of
vegetative
bacteria,
including
mycobacteriaj
fungus
and
fungal
spores.
-Area
of impact
B:
Suitable
for
deactivating
viruses.
-
Area
of
impact
C:
To
deactivate
anthrax
spores.
In
the
event
of
officially
directed
disinfection,
the
first
wash
liquor
may
not
be
discharged
until
after
disinfection
has
been
carried
out.
