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
(h) Any damage to lifting attachments or handling equipment interface features; or
(i) Any damage to service or operational equipment.
Provisions for the carriage in bulk when the provisions of 126.96.36.199 (a) are applied
In addition to the general provisions of section 7.3.1, the provisions of this section are applicable. The
codes BK1, BK2 and BK3 in column (10) of Table A of Chapter 3.2 have the following meanings:
BK1: Carriage in bulk in sheeted bulk containers is permitted;
BK2: Carriage in bulk in closed bulk containers is permitted.
BK3: Carriage in flexible bulk containers is permitted
The bulk container used shall conform to the requirements of Chapter 6.11.
Goods of Class 4.2
The total mass carried in a bulk container shall be such that its spontaneous ignition temperature is
greater than 55 °C.
Goods of Class 4.3
These goods shall be carried in bulk containers which are waterproof.
Goods of Class 5.1
Bulk containers shall be so constructed or adapted that the goods cannot come into contact with wood
or any other incompatible material.
Goods of Class 6.2
Animal material containing infectious substances (UN Nos. 2814, 2900 and 3373) is authorized for
carriage in bulk containers provided the following conditions are met:
(a) Sheeted bulk containers BK1 are permitted provided that they are not filled to maximum
capacity to avoid substances coming into contact with the sheeting. Closed bulk containers
BK2 are also permitted;
(b) Closed and sheeted bulk containers, and their openings, shall be leak-proof by design or by the
fitting of a suitable liner;
(c) The animal material shall be thoroughly treated with an appropriate disinfectant before
loading prior to carriage;
(d) Sheeted bulk containers shall be covered by an additional top liner weighted down by
absorbent material treated with an appropriate disinfectant;
(e) Closed or sheeted bulk containers shall not be re-used until after they have been thoroughly
cleaned and disinfected.
NOTE: Additional provisions may be required by appropriate national health authorities.
