(2) It is not permitted to store contaminated media if the contamination in question changes
the behaviour of the substance.
4.1.2
Usable container volume
The permissible fill level of containers must be determined in such a way that the containers
cannot overflow. Excess pressures that may jeopardise the tightness or stability of the
containers must not
arise.
The permissible fill level of the containers is to be determined in
accordance with Annex 5. The overfill protection is to be configured accordingly.
4.1.3
Documents
The container manufacturer must provide the unit operator with the following documents:
-
Copy of this decision;
-
Copy of the regulations governing the items of equipment delivered;
-
Assembly instructions for the installation of the containers.
4.1.4
Operation
(1)
Prior to commissioning of the containers/container system, the operator must affix, in a
suitable place, a sign, that is to be visible at all times, with details of the liquid being stored,
as described in Section 1(3), including its density and concentration. This shall be without
prejudice to any labelling required by other legislation.
(2) The operating regulations set out in the German Ordinance on Installations for Handling
Substances
Hazardous
to Water
[Verordnung
wassergefährdenden Stoffen - AwSV] must be
(3) Prior to
filling,
a check must be carried out to ensure that the medium to be stored
corresponds to that named on the sign referred to in Paragraph (1) and that the temperature
of the medium with which the container is to be filled will not cause the permissible operating
temperature set out in Section 1(3) to be
exceeded.
out to establish the amount of liquid that the container is able to store and whether the overfill
protection is in good condition.
(4)
The containers may only be filled using fixed connections and an overfill protection
system that automatically interrupts filling or triggers an acoustic alarm in good time before
the permissible fill level is reached. This does not apply to containers that are equipped with
a self-closing delivery nozzle and that are filled in free flow at fill rates of up to 200 l/min.
(5) Filling must be carried out under supervision at all
compliance with the permissible fill level set out in Section 4.1.2 must be checked.
(6) For the purposes of the scope of application governed by this decision (static storage),
the containers must be emptied prior to their transportation. The position in which filled or
partially filled containers have been installed cannot be changed.
(7) It is not permitted to repeatedly fill the containers with different
(8) When using the containers for the purposes of storing used lubricating, hydraulic and heat
transfer oils, and used photochemicals, these shall constitute collection containers with
nozzles allowing for the safe connection of a fixed pipeline or removable line for use by
qualified personnel (not for general
use).
4.2
Upkeep and maintenance
(1) Measures to rectify damage are to be clarified in consultation with a competent expert in
the field of plastics

(2) The use of solvents to clean the insides of containers (e.g. for the purposes of an
inspection) is not
permitted.
Accident prevention regulations and provisions governing the
use of chemical cleaning agents and the disposal of any residues must be observed.

Inspections
4.3.1
Functional inspection/pre-commissioning inspection
(1) Once the containers have been installed and the corresponding pipelines and safety
equipment have been assembled, a functional inspection must be carried
of a visual inspection, a leak test, an inspection of the filling, ventilation and extraction lines
and other such facilities.
(2) The functional inspection is not intended to replace the mandatory pre-commissioning
inspection, which must be carried out by an expert in accordance with water law; however, it
is possible to carry out both inspections at the same time.
4.3.2
Ongoing inspections/post-commissioning inspections
(1) The operator must perform a visual inspection at least once per week to ensure that the
containers are not leaking. In the event that a leak is discovered, the unit must be taken out
of service immediately and the damaged container must be emptied if necessary.
(2) The operational inspection of the items of equipment must be carried out in accordance
with their respective
regulations.
(3) If the containers are operated in an area at risk of earthquakes, a specialist company
within the meaning of Section 62 of the AwSV
operation is ensured after the occurrence of an earthquake.
(4)
This shall be without prejudice to any inspections required by other legislation.
