Except as provided in 126.96.36.199.2:
- combination packagings having inner packagings containing liquids;
- single packagings fitted with vents; and
- cryogenic receptacles intended for the carriage of refrigerated liquefied gases,
shall be legibly marked with package orientation arrows which are similar to the illustration shown
below or with those meeting the specifications of ISO 780:1997. The orientation arrows shall appear
on two opposite vertical sides of the package with the arrows pointing in the correct upright direction.
They shall be rectangular and of a size that is clearly visible commensurate with the size of the
package. Depicting a rectangular border around the arrows is optional.
Orientation arrows are not required on:
(a) Outer packagings containing pressure receptacles except cryogenic receptacles;
(b) Outer packagings containing dangerous goods in inner packagings each containing not more
than 120 ml, with sufficient absorbent material between the inner and outer packagings to
completely absorb the liquid contents;
(c) Outer packagings containing Class 6.2 infectious substances in primary receptacles each
containing not more than 50 ml;
(d) Type IP-2, type IP-3, type A, type B(U), type B(M) or type C packages containing Class 7
(e) Outer packagings containing articles which are leak-tight in all orientations (e.g. alcohol or
mercury in thermometers, aerosols, etc.); or
(f) Outer packagings containing dangerous goods in hermetically sealed inner packagings each
containing not more than 500 ml.
Arrows for purposes other than indicating proper package orientation shall not be displayed on a
package marked in accordance with this sub-section.
Labelling of packages
For each article or substance listed in Table A of Chapter 3.2, the labels shown in Column (5) shall be
affixed unless otherwise provided for by a special provision in Column (6).
Indelible danger marks corresponding exactly to the prescribed models may be used instead of labels.
Except as provided in 188.8.131.52.1.2, each label shall:
(a) be affixed to the same surface of the package, if the dimensions of the package allow; for
packages of Class1 and 7, near the mark indicating the proper shipping name;
(b) be so placed on the package that it is not covered or obscured by any part or attachment to the
packaging or any other label or marks; and
(c) be displayed next to each other when more than one label is required.
Where a package is of such an irregular shape or small size that a label cannot be satisfactorily
affixed, the label may be attached to the package by a securely affixed tag or other suitable means.
Intermediate bulk containers of more than 450 litres capacity and large packagings shall be labelled
on two opposite sides.
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
(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
(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 184.108.40.206 and 220.127.116.11 respectively.
