CLEANING AND DISINFECTION
Cleaning agents and disinfectants shall be used in such a manner that no health hazard
can occur during operation (care should be taken to read the instructions for use of the
agents and to wear protective clothing and gloves)!
•
To stop the growth and kill microorganisms, use only chemical disinfectant using
the surface disinfectants listed below.
•
For effective disinfection (microbicidal effect) the following procedure should be
followed:
1)
Mechanical removal of coarse dirt - wiping, sweeping using suitable
agents such as:
-
brushes with natural or artificial bristles
-
soft rags for cleaning machine surfaces, etc.
-
rowels, brooms - must not be placed on the floor, they must hang
(organic impurities generally reduce the effect of disinfectants)
2)
Rinse with warm drinking water
3)
Cleaning (sanitation) - application of the cleaning solution according
to the manufacturer's instructions given on the product label
(observance: exposure times, concentrations, temperatures, pH of
water)
-
without sufficient sanitation, microorganisms are protected by
impurities (biofilms are formed, etc.) and disinfectants cannot act
sufficiently
-
removes inorganic and organic substances, reduces the initial
number of microbes
4)
Rinsing with warm soft, biologically harmless water - removal of
residual dirt and detergents
5)
Visual inspection of cleanliness
6)
Disinfection - application of the disinfectant solution according to
the manufacturer's instructions on the label. These factors have a
particular effect on the effectiveness of disinfection:
-
tightness of the contact of the disinfectant with the surface - the
tighter the contact, the shorter the disinfection time and the
stronger the effect
-
sufficient temperature of the solution - in general, a higher
temperature guarantees a better disinfecting effect, but pay
attention to work safety and the possibility of disintegration of
some disinfectants
-
concentration - in general a higher concentration guarantees a
better disinfecting effect, but a low concentration is disinfectant
ineffective, on the contrary too high leads to damage to the
disinfected material
