Dangerous Goods by Road
Special provisions for the labelling of self-reactive substances and organic peroxides
(a) The label conforming to model No. 4.1 also implies that the product may be flammable and
hence no label conforming to model No. 3 is required. In addition, a label conforming to model
No. 1 shall be applied for self-reactive substances Type B, unless the competent authority has
permitted this label to be dispensed with for a specific packaging because test data have proven
that the self-reactive substance in such a packaging does not exhibit explosive behaviour.
(b) The label conforming to model No. 5.2 also implies that the product may be flammable and
hence no label conforming to model No. 3 is required. In addition, the following labels shall be
applied:
(i) A label conforming to model No. 1 for organic peroxides type B, unless the competent
authority has permitted this label to be dispensed with for a specific packaging because
test data have proven that the organic peroxide in such a packaging does not exhibit
explosive behaviour;
(ii) A label conforming to model No. 8 is required when Packing Group I or II criteria of
Class 8 are met.
For self-reactive substances and organic peroxides mentioned by name, the labels to be affixed are
indicated in the list found in 2.2.41.4 and 2.2.52.4 respectively.
Special provisions for the labelling of infectious substances packages
In addition to the label conforming to model No. 6.2, infectious substances packages shall bear any
other label required by the nature of the contents.
Special provisions for the labelling of radioactive material
Except when enlarged labels are used in accordance with 5.3.1.1.3, each package, overpack and
container containing radioactive material shall bear the labels conforming to the applicable models
Nos. 7A, 7B or 7C, according to the appropriate category. Labels shall be affixed to two opposite
sides on the outside of the package or overpack or on the outside of all four sides of a container or
tank. In addition, each package, overpack and container containing fissile material, other than fissile
material excepted under the provisions of 2.2.7.2.3.5 shall bear labels conforming to model No.7E;
such labels, where applicable, shall be affixed adjacent to the labels conforming to the applicable
model Nos. 7A, 7B or 7C.. Labels shall not cover the marks specified in 5.2.1. Any labels which do
not relate to the contents shall be removed or covered.
Each label conforming to the applicable model No. 7A, 7B or 7C shall be completed with the
following information.
(a) Contents:
(i) except for LSA-I material, the name(s) of the radionuclide(s) as taken from
Table 2.2.7.2.2.1, using the symbols prescribed therein. For mixtures of radionuclides,
the most restrictive nuclides shall be listed to the extent the space on the line permits.
The group of LSA or SCO shall be shown following the name(s) of the radionuclide(s).
The terms "LSA-II","LSA-III", "SCO-I" and "SCO-II" shall be used for this purpose;
(ii) for LSA-I material, only the term "LSA-I" is necessary; the name of the radionuclide is
not necessary;
(b) Activity: The maximum activity of the radioactive contents during carriage expressed in
becquerels (Bq) with the appropriate SI prefix symbol (see 1.2.2.1). For fissile material, the
total mass of fissile nuclides in units of grams (g), or multiples thereof, may be used in place of
activity;
(c) For overpacks and containers the "contents" and "activity" entries on the label shall bear the
information required in (a) and (b) above, respectively, totalled together for the entire contents
of the overpack or container except that on labels for overpacks or containers containing mixed
loads of packages containing different radionuclides, such entries may read "See Transport
Documents";
(d) Transport index: The number determined in accordance with 5.1.5.3.1 and 5.1.5.3.2 (no
transport index entry is required for category I-WHITE).
Each label conforming to the model No. 7E shall be completed with the criticality safety index (CSI)
as stated in the certificate of approval applicable in the countries through or into which the
consignment is carried and issued by the competent authority or as specified in 6.4.11.2 or 6.4.11.3.
For overpacks and containers, the label conforming to model No. 7E shall bear the sum of the
criticality safety indexes of all the packages contained therein.
In all cases of international carriage of packages requiring competent authority approval of design or
shipment, for which different approval types apply in the different countries concerned by the
shipment, labelling shall be in accordance with the certificate of the country of origin of design.
Provisions for labels
Labels shall satisfy the provisions below and conform, in terms of colour, symbols and general
format, to the models shown in 5.2.2.2.2. Corresponding models required for other modes of
transport, with minor variations which do not affect the obvious meaning of the label, are also
acceptable.
NOTE: Where appropriate, labels in 5.2.2.2.2 are shown with a dotted outer boundary as provided
for in 5.2.2.2.1.1. This is not required when the label is applied on a background of contrasting
colour.
Labels shall be configured as shown in Figure 5.2.2.2.1.1.
Figure 5.2.2.2.1.1
Class/division label
* The class or for Classes 4.1, 4.2 and 4.3, the figure "4" or for Classes 6.1 and 6.2, the figure "6",
shall be shown in the bottom corner.
** Additional text/numbers/symbol/letters shall (if mandatory) or may (if optional) be shown in this
bottom half.
*** The class symbol or, for divisions 1.4, 1.5 and 1.6, the division number and for Model No 7E the
word "FISSILE" shall be shown in this top half.
Labels shall be displayed on a background of contrasting colour, or shall have either a dotted or solid
outer boundary line.
The label shall be in the form of a square set at an angle of 45° (diamond-shaped). The minimum
dimensions shall be 100 mm x 100 mm and the minimum width of the line inside the edge forming
the diamond shall be 2 mm. The line inside the edge shall be parallel and 5 mm from the outside of
that line to the edge of the label. The line inside the edge on the upper half of the label shall be the
same colour as the symbol and the line inside the edge on the lower half of the label shall be the same
colour as the class or division number in the bottom corner. Where dimensions are not specified, all
features shall be in approximate proportion to those shown.
If the size of the package so requires the dimensions may be reduced, provided the symbols and other
elements of the label remain clearly visible. The line inside the edge shall remain 5 mm to the edge of
the label. The minimum width of the line inside the edge shall remain 2 mm. Dimensions for cylinders
shall comply with 5.2.2.2.1.2.
Cylinders for Class 2 may, on account of their shape, orientation and securing mechanisms for
carriage, bear labels representative of those specified in this section and the environmentally
hazardous substance mark when appropriate, which have been reduced in size, according to the
dimensions outlined in ISO 7225:2005, "Gas cylinders - Precautionary labels", for display on the
non-cylindrical part (shoulder) of such cylinders.
NOTE: When the diameter of the cylinder is too small to permit the display of the reduced size labels
on the non-cylindrical upper part of the cylinder, the reduced sized labels may be displayed on the
cylindrical part.
Notwithstanding the provisions of 5.2.2.1.6, labels and the environmentally hazardous substance mark
(see 5.2.1.8.3) may overlap to the extent provided for by ISO 7225:2005. However, in all cases, the
primary risk label and the figures appearing on any label shall remain fully visible and the symbols
recognizable.
Empty uncleaned pressure receptacles for gases of Class 2 may be carried with obsolete or damaged
labels for the purposes of refilling or inspection as appropriate and the application of a new label in
conformity with current regulations or for the disposal of the pressure receptacle.
