4.3.2 Pipelines
(1) Ventilation lines shall be adequately dimensioned and it will not be possible to seal them
off. They and their pipe connections shall be designed such that they remain tight at a gauge
pressure of 0.3 bar. Outlet holes shall be protected against the ingress of rainwater.
(2) Ventilation lines or devices shall not have their outlet in closed spaces. This does not
apply to individually installed containers with a volume of up to 1000 l for storing liquids as per
section 1 (3), items 1 to 4.
(3) Several containers may be connected to the same ventilation line only if the liquids they
store and/or their vapours do not combine to produce dangerous compounds.
(4) When connecting the pipelines to container nozzles, care shall be taken not to exert any
force and to ensure that the containers are not subjected to any additional, unforeseen
external loads.
4.3.3 Installation conditions for storing media according to section 1 (3), items 1 to 4
When storing media according to section 1 (3), items 1 to 4, TRwS 791-1
must be complied with in respect of the installation conditions.
4.4 Documentation and confirmation of conformity
The company performing this task shall produce confirmation of conformity that confirms
correct erection, installation and assembly in conformity with the manufacturer's installation
instructions and the provisions of the national technical approval, under consideration of
technical approval of the suitability of equipment and accessories. This confirmation shall be
submitted to the operator in each individual case, who will store it in the building file.
5 Provisions for use, maintenance, servicing and inspection
5.1 Use
5.1.1 Stored liquids
(1) The containers may be used for the storage of liquids hazardous to water as per section 1
(3), with the limitations mentioned therein.
(2) The storage of contaminated liquids is not permitted if this contamination would change
the behaviour of the material.
5.1.2 Useful container volume
(1) The permissible fill level of containers must be dimensioned such that the containers do
not overflow. Excess pressures that adversely affect the tightness or strength of the
containers must not occur.
(2) The permissible fill level of the containers shall be determined in accordance with Annex
5. The overfill protection device shall be set up accordingly.
(3) For liquids with a cubic coefficient of expansion of α ≤ 1.50 · 10
classified as toxic or caustic in accordance with (EU) regulation no. 1272/2008 (CPL
Regulation), paragraph (1) can be deemed to be complied with if the fill level does not exceed
95% of the capacity.

5.1.3 Documentation
The container manufacturer must give the following documents to the system operator:
- Copy of National Technical Approval Z-40.21-288;
- Copy of the technical approval of suitability of an overfill protection device (if included in
scope of delivery),
- Copy of the technical approval of suitability of a leak detector (if included in scope of
delivery),
- Installation instructions for container erection.
5.1.4 Operation
(1) Before commissioning the container or the container system, the operator shall affix a
permanent, visible sign in a suitable location, providing information on the stored liquid as per
section 1 (3), including its density and concentration. Identification required by other
regulations shall not be affected.
(2) The operating directives of the Act on Installations Handling Materials Hazardous to Water
shall be complied with during operation.
(3) Before filling, checks shall be performed to ensure that the liquid in question matches that
on the sign described in paragraph (1), and that the temperature of the liquid will not result in
the exceeding of the permitted operating temperature as per section 1 (3). In addition, a
check shall be carried out to verify how much stored liquid the container can hold, and
whether the overfill protection device is working properly.
(4) The containers may only be filled via fixed connections and only with the use of an overfill
protection device that automatically interrupts the filling process or triggers an acoustic alarm
in good time before the permitted liquid level is reached. This does not apply to containers
with a volume that does not exceed 1000 l, if they are filled via an automatically closing
delivery nozzle at filling rates of up to 200 l/min in free flow.
(5) Filling processes shall be monitored in their entirety. When the filling process is complete,
a check shall be performed to ensure compliance with the permitted fill level as per section
5.1.2.
(6) The containers may only be transported empty and for the purpose of the application
(stationary storage) described herein. The installation position of the containers when full or
partially full shall not be changed.
(7) Containers shall not be filled alternately with different liquids.
(8) For use of the containers to store used lubricating, hydraulic and heat transfer oils and
used photo chemicals, collection containers with nozzles for secure connection of a
permanent pipe or removable line are used by trained technicians (not by just anyone).
5.2 Maintenance, servicing
(1) The storage facility operator undertakes to entrust container maintenance and cleaning
only to companies that are specialist firms for these activities within the meaning of § 3 of the
Act for Installations Handling Materials Hazardous to Water
been exempted from the obligation to employ a specialist company by German state
regulations, or the manufacturer of the containers performs this work with its own specialist
personnel.
(2) Measures to correct damage shall be clarified with a competent expert in synthetic
11
materials , possibly with the involvement of the applicant.

(3) Solvents shall not be used to clean the inside of tanks (e.g. for an inspection). The
accident prevention regulations, provisions governing the use of chemical cleaning agents
and the disposal of cleaning waste shall be observed.
5.3 Inspections
5.3.1 Performance test/Inspection before commissioning
(1) A performance test shall be performed after erection of the containers and installation of
the necessary pipelines and safety devices. The test shall comprise a visual inspection, a
leak test and the inspection of filling, ventilation and exhaust lines and other equipment.
(2) The performance test does not replace any pre-commissioning inspections required by
the authorities in accordance with water management laws; they may be performed at the
same time, however.
5.3.2 Ongoing Inspections/Inspections after commissioning
(1) The operator shall visually inspect the containers to ensure tightness at least once a
week. If leaks are discovered, the system shall be shut down immediately and the damaged
container drained if necessary.
(2) The performance of the leak detector being used shall be checked for conformity with the
technical approval of suitability issued by the building authorities for this leak detector.
(3) This shall not affect inspections required by other areas of law.
