Karcher HKS 100 AC [16/112] Behaviour in emergency situations
16 English
Switch off the separate high pressure
pump.
Shut off the cleaning liquid supply.
Areas that bear the risk of explosion are di-
vided into zones, according to the frequen-
cy and duration of explosion-risk
atmosphere 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 Be-
trSichV, EN 1127-1, BGR 104 – Ex-guide-
line 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 pe-
riods 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.
– 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.
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 nominal pressure of the pump must
not exceed 5 MPa when operating with
solvents.
6 The flow volume of the pump must not
exceed 50 l/m when operating with sol-
vents.
7 The speed of the cleaning head must
not exceed 40 rpm.
8 The operating temperature of the clean-
ing liquid water with cleaning agents
must not must not exceed 60 °C.
9 The operating temperature of the clean-
ing liquid solvents, brines and acids
must not must not exceed 20 °C.
10 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 applicable, a
repair needs to be conducted.
11 The interior cleaner must only be used
with cleaning liquids and in such media,
whose affect on the materials is not
damaging.
12 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.
13 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 contain-
er is not resistant to breakdown from
flames.
14 Hoses must be conductive (electrostati-
cally) (resistance R < 1000 Ohm).
15 Only cleaning agents with a conductivity
G > 1000 pS/m may be used.
16 All parts that touch media must be con-
nected to the grounding system.
