Chapter 3.5Dangerous goods packed in excepted quantities
3.5.1 Excepted quantities
3.5.1.1 Excepted quantities of dangerous goods
of certain classes, other than articles, meeting the provisions of
this chapter are not subject to any other provisions of this Code
except for:
-

-
.2 The classification procedures and packing group

alphanumeric code as follows:

For gases, the volume indicated for inner packagings refers
to the water capacity of the inner receptacle and the volume indicated
for outer packagings refers to the combined water capacity of all
inner packagings within a single outer packaging.
3.5.1.3 Where dangerous goods in excepted quantities
for which different codes are assigned are packaged together the total
quantity per outer packaging shall be limited to that corresponding
to the most restrictive code.
3.5.2 Packagings
3.5.2.1 Packagings used for the transport of dangerous
goods in excepted quantities shall be in compliance with the following:
-
.1 There shall be an inner packaging and each
inner packaging shall be constructed of plastic (when used for liquid
dangerous goods it shall have a thickness of not less than 0.2 mm),
or of glass, porcelain, stoneware, earthenware or metal (see also
4.1.1.2) and the closure of each inner packaging shall be held securely
in place with wire, tape or other positive means; any receptacle having
a neck with moulded screw threads shall have a leak proof threaded
type cap. The closure shall be resistant to the contents;
-
.2 Each inner packaging shall be securely packed
in an intermediate packaging with cushioning material in such a way
that, under normal conditions of transport, they cannot break, be
punctured or leak their contents. The intermediate packaging shall
completely contain the contents in case of breakage or leakage, regardless
of package orientation. For liquid dangerous goods, the intermediate
packaging shall contain sufficient absorbent material to absorb the
entire contents of the inner packaging. In such cases, the absorbent
material may be the cushioning material. Dangerous goods shall not
react dangerously with cushioning, absorbent material and packaging
material or reduce the integrity or function of the materials;
-
.3 The intermediate packaging shall be securely
packed in a strong, rigid outer packaging (wooden, fibre-board or
other equally strong material);
-
.4 Each package type shall be in compliance with
the provisions in 3.5.3;
-
.5 Each package shall be of such a size that there
is adequate space to apply all necessary markings; and
-
.6 Overpacks may be used and may also contain
packages of dangerous goods or goods not subject to the provisions
of this Code.
3.5.3
Tests for packages
3.5.3.1 The complete package as prepared for transport,
with inner packagings filled to not less than 95% of their capacity
for solids or 98% for liquids, shall be capable of withstanding, as
demonstrated by testing which is appropriately documented, without
breakage or leakage of any inner packaging and without significant
reduction in effectiveness:
Note: Each of the above drops may be performed
on different but identical packages.
3.5.3.2 For the purposes of testing, the substances
to be transported in the packaging may be replaced by other substances
except where this would invalidate the results of the tests. For solids,
when another substance is used, it shall have the same physical characteristics
(mass, grain size, etc.) as the substance to be carried. In the drop
tests for liquids, when another substance is used, its relative density
(specific gravity) and viscosity shall be similar to those of the
substance to be transported.
3.5.4 Marking of packages
3.5.4.1 Packages containing excepted quantities
of dangerous goods prepared in accordance with this chapter shall
be durably and legibly marked with the mark shown below. The primary
hazard class of each of the dangerous goods contained in the package
shall be shown in the mark. Where the name of the consignor or consignee
is not shown elsewhere on the package this information shall be included
within the mark.
3.5.4.2 The dimensions of the mark shall be a
minimum of 100 mm x 100 mm.
3.5.4.3 An overpack containing dangerous goods
in excepted quantities shall display the markings required by 3.5.4.1,
unless such markings on packages within the overpack are clearly visible.
3.5.5 Maximum number of packages in any cargo transport
unit
3.5.5.1 The number of packages containing dangerous
goods packed in excepted quantities in any cargo transport unit shall
not exceed 1,000.
3.5.6 Documentation
3.5.6.1 In addition to the provisions for documentation
specified in chapter 5.4, the words “dangerous goods in excepted
quantities” and the number of packages shall be included on
the dangerous goods declaration together with the description of the
shipment.
3.5.7 Stowage
3.5.7.1 Notwithstanding the stowage provisions
indicated in the Dangerous Goods List, dangerous goods transported
under the provisions of this chapter are allocated stowage category
A.
3.5.8 Segregation
3.5.8.1 The segregation provisions of chapter
7.2 are not applicable for packagings containing dangerous goods in
excepted quantities or in relation to other dangerous goods.
3.5.8.2 The segregation provisions of chapter
7.2 are not applicable for different dangerous goods in excepted quantities
in the same outer packaging provided that they do not react dangerously
with each other (see 4.1.1.6
