5.1.5 Operation
5.1.5.1 General instructions
(1) Before commissioning the container, the operator must
affi x a plate at a suitable place, identifying the stored liquid and
stating its density and its concentration.
The labelling requirements of other directives are not affected by
this and must also be satisfi ed.
(2) The operating directives of TRbF 20 and the Ordinance for
Facilities and Companies Handling Substances Hazardous to
Water (VAwS) apply.
5.1.5.2 Filling and emptying
(1) Before fi lling, check whether the liquid to be stored is
approved, matches the designation of the container, and is at
a temperature allowed in Sec. 5.1.5.3. In addition, check how
much liquid can be stored in the container and whether the
overfi ll safety device, if required, is in good operating condition.
(2) Filling and emptying requires a fi xed, stably installed line
(pipe or hose) unless the water and work safety directives allow
an exception.
(3) Containers for storing heating oil complying with DIN
51 603 and diesel fuel complying with DIN EN 590 are not
subject to the requirements of Sec. (2) and may be fi lled from
a tank vehicle or portable tank with a full hose system using an
insertable automatic cut-off fuel pump nozzle, at fi lling rates of
up to 1200 I/min.
(4) Filling must be completely supervised.
5.1.5.3 Further conditions
(1) The operating temperature of the stored liquid must not
exceed 30° C. However, for short times, temperatures of 10 K
above the operating temperature (such as higher temperature of
the storage liquid when fi lling) are excepted.
(2) When storing used lubricating, hydraulic and heat transfer
oils and used photochemicals, the container is used as a
collection container, with a connector for securely connecting
a permanent pipeline or a removable line for use by trained
technicians (not by everyone).
5.2
Maintenance and servicing
(1) The operator of a storage facility is obliged to employ for
maintenance and cleaning of the containers only those busines-
ses which are specialists for this work in the meaning of
§ 19 I of the Water Resources Act
cepted by state regulations from requiring specialist companies.
(2) Deviating from (1), maintenance tasks may also be carried
out by the container manufacturer's own technical personnel.
(3) For storing fl ammable liquids, activities described in (1)
must be carried out by companies that are considered qualifi ed
specialists according to TRbF 20 No. 15.4.
(4) Steps to remedy damages should be decided in consultation
with an expert in water directives or the certifi cation agency.

(5) Cleaning the inside of containers with solvents, for example,
for an inspection, is not allowed. The accident prevention direc-
tives and directives for use of chemical cleaning agents and the
disposal of cleaning waste must be observed.
5.3
Tests
5.3.1 Performance test / test before commissioning
(1) After installing the container and mounting the pipelines and
safety devices, a performance test is necessary. It consists of
visual examination, a leak test, testing of the pipes and fi ttings
and other accoutrements.
(2) A performance test does not replace a necessary test before
commissioning by a specialist for water directives; however, the
two can be performed together.
5.3.2 Ongoing tests / tests after commissioning
(1) The operator must examine the containers visually for leaka-
ge at least once per week.
As soon as leakage is discovered, the unit must be taken out of
operation and the damaged container emptied.
(2) The leak detector used as described in Sec. 1 (1) or Section
5.1.1 (3) is to be checked for proper operation according to the
specifi cations in the general construction inspection approval for
that leak detector.
(3) Tests as required by other directives are not affected by this
and must also be satisfi ed.
