Personal protective equipment
CAUTION
 Wear protective clothing and safety
goggles to protect against splash back
containing water or dirt.
 During the use of high-pressure clean-
ers aerosols can develop. Inhaling aer-
osols can cause health damage.
Depending on the application, com-
pletely shielded nozzles (e.g. surface
cleaner) that significantly reduce the
emission of aqueous aerosols can be
used for high-pressure cleaning.
The use of such shielding is not possi-
ble with all applications.
If the use of a completely shielded noz-
zle is not possible, a respirator of the
category FFP 2 or the like should be
used, depending on the environment to
be cleaned.
