General provisions

Goods may not be carried in bulk in bulk containers, containers or vehicles unless:
(a) either a special provision, identified by the code "BK" or a reference to a specific paragraph,
explicitly authorizing this mode of carriage is indicated in column (10) of Table A of Chapter
3.2 and the relevant conditions of 7.3.2 are satisfied in addition to those of this section; or
(b) a special provision, identified by the code "VC" or a reference to a specific paragraph, explicitly
authorizing this mode of carriage is indicated in column (17) of Table A of Chapter 3.2 and the
conditions of this special provision, together with any additional provision identified by the code
"AP", as laid down in 7.3.3 are satisfied in addition to those of this section.
Nevertheless, empty packagings, uncleaned, may be carried in bulk if this mode of carriage is not
explicitly prohibited by other provisions of ADR.
NOTE: For carriage in tanks, see Chapters 4.2 and 4.3.

Substances which may become liquid at temperatures likely to be encountered during carriage, are not
permitted for carriage in bulk.

Bulk containers, containers or bodies of vehicles shall be siftproof and shall be so closed that none of
the contents can escape under normal conditions of carriage including the effect of vibration, or by
changes of temperature, humidity or pressure.

Substances shall be loaded and evenly distributed in a manner that minimises movement that could
result in damage to the bulk container, container or vehicle or leakage of the dangerous goods.

Where venting devices are fitted they shall be kept clear and operable.

Substances shall not react dangerously with the material of the bulk container, container, vehicle,
gaskets, equipment including lids and tarpaulins and with protective coatings which are in contact
with the contents or significantly weaken them. Bulk containers, containers or vehicles shall be so
constructed or adapted that the goods cannot penetrate between wooden floor coverings or come into
contact with those parts of the bulk container, container or vehicle that may be affected by the
materials or residues thereof.

inspected and cleaned to ensure that it does not contain any residue on the interior or exterior of the
bulk container, container or vehicle that could:
- cause a dangerous reaction with the substance intended for carriage;
- detrimentally affect the structural integrity of the bulk container, container or vehicle; or
- affect the dangerous goods retention capabilities of the bulk container, container or vehicle.

During carriage, no dangerous residues shall adhere to the outer surfaces of bulk containers,
containers or of the bodies of vehicles.

If several closure systems are fitted in series, the system which is located nearest to the substance to
be carried shall be closed first before filling.

Empty bulk containers, containers or vehicles which have carried a dangerous solid substance in bulk
shall be treated in the same manner as is required by ADR for a filled bulk container, container or
vehicle, unless adequate measures have been taken to nullify any hazard.

If bulk containers, containers or vehicles are used for the carriage in bulk of goods liable to cause a
dust explosion, or evolve flammable vapours (e. g. for certain wastes) measures shall be taken to
exclude sources of ignition and prevent dangerous electrostatic discharge during carriage, filling or
discharge of the substance.

 

Substances, for example wastes, which may react dangerously with one another and substances of
different classes and goods not subject to ADR, which are liable to react dangerously with one another
shall not be mixed together in the same bulk container, container or vehicle. Dangerous reactions are:
(a) Combustion and/or evolution of considerable heat;
(b) Emission of flammable and/or toxic gases;
(c) Formation of corrosive liquids; or
(d) Formation of unstable substances.

Before a bulk container, container or vehicle is filled it shall be visually examined to ensure it is
structurally serviceable, its interior walls, ceiling and floors are free from protrusions or damage and
that any inner liners or substance retaining equipment are free from rips, tears or any damage that
would compromise its cargo retention capabilities. Structurally serviceable means the bulk container,
container or vehicle does not have major defects in its structural components, such as top and bottom
side rails, top and bottom end rails, door sill and header, floor cross members, corner posts, and corner
fittings in a bulk container or container. Major defects include:
(a) Bends, cracks or breaks in the structural or supporting members that affect the integrity of the
bulk container, container or of the body of the vehicle;
(b) More than one splice or an improper splice (such as a lapped splice) in top or bottom end rails
or door headers;
(c) More than two splices in any one top or bottom side rail;
(d) Any splice in a door sill or corner post;
(e) Door hinges and hardware that are seized, twisted, broken, missing, or otherwise inoperative;
(f) Gaskets and seals that do not seal;
(g) Any distortion of the overall configuration of a bulk container or container great enough to
prevent proper alignment of handling equipment, mounting and securing on a chassis or
vehicle;
(h) Any damage to lifting attachments or handling equipment interface features; or
(i) Any damage to service or operational equipment.
