Personal safety gear
Wear ear plugs to protect
your ears against hearing
loss while cleaning parts
that produce high sound
levels.
Depending on the concentration and health
risk of the used cleaning liquid, wear the fol-
lowing protective gear:
– Liquid resistant protective clothing
– Protective glasses or face shield
– Protective gloves
– Protective shoes
Approved operators
Approved operators are persons who are at
least 18 years old and are able to operate
this system (exceptions: apprentices, see
BGV D15 §6).
Behaviour in emergency situations
 Switch off the separate high pressure
pump.
 Shut off the cleaning liquid supply.
Zone layout
Areas that bear the risk of explosion are di-
vided into zones, according to the frequen-
cy and duration of explosion-risk atmos-
phere in BetrSichV and EN 1127-1.
The definition of the zones lies in the re-
sponsibility of the operator.
Tips for zoning are included in the BetrSi-
chV, EN 1127-1, BGR 104 – Ex-guideline
of BG Chemie and in the EN 60079-10.
– Zone 0
Zone 0 is an area where dangerous ex-
plosion-risk atmosphere is present as a
mixture of air and flammable gases, va-
pors or mists at all times, across long
time periods or frequently.
– Zone 1
Zone 1 is an area where (during normal
operation) dangerous explosion-risk at-
mosphere is present as a mixture of air
and flammable gases, vapors or mists
from time to time.
– Zone 2
Zone 2 is an area where (during normal
operation) dangerous explosion-risk at-
mosphere as a mixture of air and flam-
mable gases, vapors or mists is not
normally present and if present, only for
a short time.
– Zone 20
Zone 20 is an area where dangerous
explosion-risk atmosphere is present
as a cloud of flammable dust contained
in the air, at all times, across long time
periods or frequently.
– Zone 21
Zone 21 is an area where (during nor-
mal operation) dangerous explosion-
risk atmosphere is present as a cloud of
flammable dust in the air from time to
time.
16
– Zone 22
Zone 22 is an area where (during nor-
mal operation) dangerous explosion-
risk atmosphere as a cloud of flamma-
ble dust is not normally present and if
present, only for a short time.
Special conditions in the Ex area
1 The interior cleaner must only be used
in Zone 0 if the containers are at least 3
m in diameter with the usual container
height or do not exceed a comparable
container size.
2 The mass content of non-diluted solid
substances in the cleaning liquid must
not exceed 1%.
3 The interior cleaner must be ground
electro-statically.
4 The pump for the cleaning liquid must
only be operated while it is filled with flu-
id.
5 The speed of the cleaning head must
not exceed 40 rpm in cold operation.
6 The operating temperature of the clean-
ing liquid water with cleaning agents
must not exceed 60 °C.
7 The operating temperature of the clean-
ing liquids, brines and acids must not
must not exceed 20 °C.
8 The interior cleaner must be checked
for flawless condition and function after
an appropriate operating period
(among others, bearings for wear and
brake system for its function). If applica-
ble, a repair needs to be conducted by
the customer service.
9 The interior cleaner must only be used
with cleaning liquids and in such media,
whose affect on the materials is not
damaging.
10 Cleaning liquids that contain flammable
solvent particles, must comply with the
ignition groups IIA and IIB. Solvents of
the ignition group IIC must not be
sprayed.
11 The interior cleaner must not be con-
stantly located in Zone 0, but only dur-
ing the actual container cleaning. The
operating guidelines as per BetrSichV
as well as other national guidelines
must be adhered to. Take into consider-
ation, that the mixture of the container/
interior cleaner brought into the con-
tainer is not resistant to breakdown
from flames.
12 Hoses must be conductive (electrostat-
ically) (resistance R < 1000000 Ohm).
13 Only cleaning agents with a conductivi-
ty G > 1000 pS/m may be used.
14 All parts that touch media must be con-
nected to the grounding system.
