Annexes
§ 2. The non-accessible pipes must be fitted in a ditch that must be filled in with a fine-grained
inert material. This ditch must be impervious and must slope down to an impervious collection
well.
This system may be replaced by an alternative system which offers the same guarantees as regards
the prevention of ground and/or groundwater pollution. The alternative system must be
accepted by an environmental expert accredited in the discipline containers for gases or hazardous
substances. A certificate of this acceptance is drawn up and signed by the aforementioned
environmental expert. This certificate is kept available for the perusal of the supervisory official.
A copy of the certificate will be forwarded by the operator to the Environmental Licence
Department.
§ 3.The fitting of piping for the transport of P1 and/or P2 products inside spaces is prohibited,
except if such piping is made of a single tube (no couplings with seals), or if the spaces have
been laid out and zoned in accordance with the requirements referred to in the general regulations
for electrical installations, in particular the articles dealing with spaces in which an explosive
atmosphere can originate.
Art. 5.17.1.5
§ 1. Without prejudice to further provisions, the necessary precautionary measures must be
taken to prevent products from coming into contact with each other if:
1. this could result in dangerous chemical reactions
2. such products could react with each other to form harmful or dangerous gases and vapours
3. contact between such products could result in explosions and/or fire.
§ 2. If at the establishment products with different main properties are stored, the storage facility
must be subdivided into different compartments, with in each compartment only products
being stored with the same main properties.
These compartments must be delimited by means of walls, safety screens, markings on the
ground, chains or fixed demarcations at a height of 1 metre.
However, products with different main properties may be stored together in a single compartment
if according to appendix 5.17.1 the minimum separation distance between the products is
0 metres.
§ 3. Any manufacturing operation or other treatment not concerned with the storage or transfer
of the products is prohibited inside the storage facilities and the zones delimited by the separation
distances and/or screens prescribed in appendix 5.17.1
§ 4. The products may not be stored outside the storage spaces intended for this purpose. Contaminated
empty mobile receptacles that have contained hazardous products must be stored in a
dedicated place that must be clearly indicated.
Art. 5.17.1.6
§ 1. With respect to aboveground compartments for products with a specific main property,
minimum separation distances as indicated in appendix 5.17.1 are to be observed.
§ 2. The distances specified in § 1 may be reduced by the construction of a safety screen, on the
condition that the distance measured horizontally around this screen between the compartment
concerned and the elements indicated in appendix 5.17.1 is equal to or larger than the minimum
safety distances prescribed in § 1.
The safety screen must be made either of brickwork with a thickness of at least 18 cm, or of
concrete with a thickness of at least 10 cm, or of any other material with a thickness providing
