place on the fixed container:
1. the number of the container
2. the name or the code numbers or letters of the stored liquid
3. the danger symbols
4. the water content capacity of the container.
The provisions of this paragraph are not applicable to storage sites for P3 and/or P4 products
which are only intended for the heating of buildings.
§ 3. On moveable receptacles the name of the product mentioning the main property must be

Art. 5.17.3.6
§ 1. The bund and the foundations for fixed containers with an individual water content capacity
from 10000 l must be built according to a code of good practice under the supervision of and
according to the directions of an architect, a civil engineering architect, a civil structural engineer
or an industrial architectural engineer.
For storage sites classified in category 1 or 2, the aforementioned expert confirms in a certificate
that he accepts the code of good practice used and that this was adhered to.
§ 2. Fixed containers must be placed on a supporting block or surface of sufficient dimensions
to prevent the load causing uneven slumps, from which a danger of toppling or breakage could
originate. For the installation of containers with an individual water content capacity from
50000 l a stability study is conducted by the expert specified in §1.
§ 3. The bund must be resistant to the action of the stored liquids and must be impervious. The
bund must be sufficiently strong to withstand the liquid mass which could escape in the event
of the breakage of the largest container placed in the bund.
The floor must be provided in such a way that the spreading of the leaked liquids remains minimal
and the leaked liquids can be easily removed.
§ 4. If the bund is made of earthen dams, these dams must be made of a very clayish, solid and
strongly compressed earth, of which the gradients are a max. 4/4 and the thickness on the top
side is to be at least 50 centimetres. The floor may be made of the same materials. The dams
must be sown with grass. At the base, carefully calculated supporting walls with a maximum
height of one metre may be constructed.
§ 5. The passage of ducts through the bund is only allowed if the sealing of the bund remains
assured.
§ 6. If the bund is wider than 30 metres, the escape ladders or stairs must be positioned so that a
person fleeing does not have to travel a distance greater than half the width of the bund plus
15 metres to reach an escape ladder or stairs.
