When using the device, it is necessary to distinguish between the following operating states.
Operating state - cleaning process (cleaning > cleaning agent is sprayed and spray head rotates)
In this case, flammable gases, vapors, mists or flammable dust may already be present in the container
or are only added by the intended cleaning process in the form of sprayed fluid (aerosol).
Flammable vapors and mists must be expected as soon as flammable fluids with a flash point of 15 K
above the cleaning medium temperature are sprayed, including those permitted in accordance with
Section 3.4 Cleaning Media.
For this reason, both the conditions in the container and the type and
temperature of the cleaning medium must be taken into account when defining the following three
process conditions:
A)
During cleaning, no explosive mixture is present, nor is it possible for one to develop from the
cleaning medium. (Explosive mixtures consist of flammable gases, vapors, mists or stirred-up dust
in the air or another oxidizing agent that reacts to a self-propagating flame when an ignition source
becomes active, generally causing an abrupt increase in temperature and pressure).
Pressure in the container: 0 to 0.5 bar (0 to 7.25 psi g)
Temperature of the cleaning medium: +5 °C to 180 °C
Ambient temperature in the container to be cleaned: +5 °C to +180 °C
B)
A potentially explosive atmosphere (ATEX conditions) is present during cleaning (A potentially
explosive atmosphere is a potentially explosive mixture with air as an oxidizing agent under
atmospheric conditions (ambient temperature of -20 °C to +60 °C and absolute pressure of 0.8 bar
a to 1.1 bar a, that is already present before the use of the device, or that develops when spraying a
cleaning medium during the cleaning process)
Pressure in the container: 0 to 0.1 bar (0 to 1.45 psi g)
Temperature of the NON-flammable cleaning medium: +5 °C to +60 °C
Temperature of the flammable cleaning medium: +5 °C to flash point T
flash point
-15 °C (max. +60 °C)
Ambient temperature in the container to be cleaned: +5 °C to +60 °C
C)
A potentially explosive mixture is present during cleaning, but there is no explosive atmosphere.
Cleaning is PROHIBITED! If necessary, the process conditions must be changed before using the
device so that process conditions exist in accordance with A) or B).
For processes that are outside atmospheric conditions, the owner must make a differentiated
assessment of the effects.
The necessary safety-related parameters must be determined and an additional hazard assessment
must be created for explosion hazards in order to separately verify the suitability of the device used.
The cleaning process with the TANKO-R64T tank cleaning device with TANKO-EX-S or TANKO-EX-RB
attached is prohibited in operating conditions that result in explosive mixtures outside atmospheric
conditions (outside temperatures of −20 °C to +60 °C and absolute pressures of 0.8 bar a to 1.1 bar a)
in the container to be cleaned or in the presence of oxidizing agents other than air.
The cleaning process with the TANKO-R64T tank cleaning device with TANKO-EX-S or TANKO-EX-RB
attached is also prohibited in the presence of explosive mixtures with ignitable substances such as
hydrogen, ethylene, acetylene, carbon disulfide, carbon monoxide, ethylene oxide and trichlorosilane.
