CHAPTER 4.1

USE OF PACKAGINGS, INCLUDING INTERMEDIATE
BULK CONTAINERS (IBCs) AND LARGE PACKAGINGS

4.1.1 General provisions for the packing of dangerous goods in packagings, including IBCs
and large packagings
NOTE: For the packing of goods of Class 2, Division 6.2 and Class 7, the general provisions of this
section only apply as indicated in 4.1.8.2 (Division 6.2), 4.1.9.1.5 (Class 7) and in the applicable packing
instructions of 4.1.4 (P201 and LP02 for Class 2 and P620, P621, IBC620 and LP621 for Division 6.2).

4.1.1.1 Dangerous goods shall be packed in good quality packagings, including IBCs and large
packagings, which shall be strong enough to withstand the shocks and loadings normally encountered during
transport, including trans-shipment between cargo transport units and between cargo transport units and
warehouses as well as any removal from a pallet or overpack for subsequent manual or mechanical handling.
Packagings, including IBCs and large packagings, shall be constructed and closed so as to prevent any loss
of contents when prepared for transport which may be caused under normal conditions of transport, by
vibration, or by changes in temperature, humidity or pressure (resulting from altitude, for example).
Packagings, including IBCs and large packagings, shall be closed in accordance with the information
provided by the manufacturer. No dangerous residue shall adhere to the outside of packages, IBCs and large
packagings during transport. These provisions apply, as appropriate, to new, reused, reconditioned or
remanufactured packagings, and to new, reused, repaired or remanufactured IBCs, and to new, reused or
remanufactured large packagings.

4.1.1.2 Parts of packagings, including IBCs and large packagings, which are in direct contact with
dangerous goods:
(a) Shall not be affected or significantly weakened by those dangerous goods;
(b) Shall not cause a dangerous effect e.g. catalysing a reaction or reacting with the
dangerous goods; and
(c) Shall not allow permeation of the dangerous goods that could constitute a danger
under normal conditions of transport.
Where necessary, they shall be provided with a suitable inner coating or treatment.

4.1.1.3 Unless otherwise provided elsewhere in these Regulations, each packaging, including IBCs
and large packagings, except inner packagings, shall conform to a design type successfully tested in
accordance with the requirements of 6.1.5, 6.3.2, 6.5.6 or 6.6.5, as applicable.

However, IBCs manufactured before 1 January 2011 and conforming to a design type which
has not passed the vibration test of 6.5.6.13 or which was not required to meet the criteria of 6.5.6.9.5 (d) at
the time it was subjected to the drop test, may still be used.

4.1.1.4 When filling packagings, including IBCs and large packagings, with liquids, sufficient ullage
(outage) shall be left to ensure that neither leakage nor permanent distortion of the packaging occurs as a
result of an expansion of the liquid caused by temperatures likely to occur during transport. Unless specific
requirements are prescribed, liquids shall not completely fill a packaging at a temperature of 55 °C.
However, sufficient ullage shall be left in an IBC to ensure that at the mean bulk temperature of 50 °C it is
not filled to more than 98% of its water capacity.

4.1.1.4.1 For air transport, packagings intended to contain liquids shall also be capable of
withstanding a pressure differential without leakage as specified in the international regulations for air
transport.
-5-


4.1.1.5 Inner packagings shall be packed in an outer packaging in such a way that, under normal
conditions of transport, they cannot break, be punctured or leak their contents into the outer packaging. Inner
packagings containing liquids shall be packed with their closures upward and placed within outer packagings
consistent with the orientation markings prescribed in 5.2.1.7 of these Regulations. Inner packagings that are
liable to break or be punctured easily, such as those made of glass, porcelain or stoneware or of certain
plastics materials, etc., shall be secured in outer packagings with suitable cushioning material. Any leakage
of the contents shall not substantially impair the protective properties of the cushioning material or of the
outer packaging.

4.1.1.5.1 Where an outer packaging of a combination packaging or a large packaging has been
successfully tested with different types of inner packagings, a variety of such different inner packagings may
also be assembled in this outer packaging or large packaging. In addition, provided an equivalent level of
performance is maintained, the following variations in inner packagings are allowed without further testing
of the package:

(a) Inner packagings of equivalent or smaller size may be used provided:

(i) The inner packagings are of similar design to the tested inner packagings
(e.g. shape - round, rectangular, etc.);

(ii) The material of construction of the inner packagings (glass, plastics, metal, etc.)
offers resistance to impact and stacking forces equal to or greater than that of
the originally tested inner packaging;

(iii) The inner packagings have the same or smaller openings and the closure is of
similar design (e.g. screw cap, friction lid, etc.);

(iv) Sufficient additional cushioning material is used to take up void spaces and to
prevent significant movement of the inner packagings; and

(v) Inner packagings are oriented within the outer packaging in the same manner as
in the tested package.

(b) A lesser number of the tested inner packagings, or of the alternative types of inner
packagings identified in (a) above, may be used provided sufficient cushioning is
added to fill the void space(s) and to prevent significant movement of the inner
packagings.

4.1.1.6 Dangerous goods shall not be packed together in the same outer packaging or in large
packagings, with dangerous or other goods if they react dangerously with each other and cause:

(a) Combustion and/or evolution of considerable heat;

(b) Evolution of flammable, toxic or asphyxiant gases;

(c) The formation of corrosive substances; or

(d) The formation of unstable substances.

4.1.1.7 The closures of packagings containing wetted or diluted substances shall be such that the
percentage of liquid (water, solvent or phlegmatizer) does not fall below the prescribed limits during
transport.

4.1.1.7.1 Where two or more closure systems are fitted in series on an IBC, that nearest to the
substance being carried shall be closed first.

-6-


4.1.1.8 Where pressure may develop in a package by the emission of gas from the contents (as a
result of temperature increase or other causes), the packaging or IBC may be fitted with a vent provided that
the gas emitted will not cause danger on account of its toxicity, its flammability or the quantity released, for
example.

A venting device shall be fitted if dangerous overpressure may develop due to normal
decomposition of substances. The vent shall be so designed that, when the packaging or IBC is in the attitude
in which it is intended to be transported, leakages of liquid and the penetration of foreign substances are
prevented under normal conditions of transport.

4.1.1.8.1 Liquids may only be filled into inner packagings which have an appropriate resistance to
internal pressure that may be developed under normal conditions of transport.

4.1.1.8.2 Venting of the package is not permitted for air transport.

4.1.1.9 New, remanufactured or reused packagings, including IBCs and large packagings, or
reconditioned packagings and repaired or routinely maintained IBCs shall be capable of passing the tests
prescribed in 6.1.5, 6.3.2, 6.5.6 or 6.6.5, as applicable. Before being filled and handed over for transport,
every packaging, including IBCs and large packagings, shall be inspected to ensure that it is free from
corrosion, contamination or other damage and every IBC shall be inspected with regard to the proper
functioning of any service equipment. Any packaging, which shows signs of reduced strength as compared
with the approved design type shall no longer be used or shall be so reconditioned, that it is able to withstand
the design type tests. Any IBC which shows signs of reduced strength as compared with the tested design
type shall no longer be used or shall be so repaired or routinely maintained that it is able to withstand the
design type tests.

4.1.1.10 Liquids shall be filled only into packagings, including IBCs, which have an appropriate
resistance to the internal pressure that may develop under normal conditions of transport. Packagings and
IBCs marked with the hydraulic test pressure prescribed in 6.1.3.1(d) and 6.5.2.2.1, respectively shall be
filled only with a liquid having a vapour pressure:

(a) Such that the total gauge pressure in the packaging or IBC (i.e. the vapour pressure of
the filling substance plus the partial pressure of air or other inert gases, less 100 kPa)
at 55 °C, determined on the basis of a maximum degree of filling in accordance
with 4.1.1.4 and a filling temperature of 15 °C, will not exceed two thirds of the
marked test pressure; or

(b) At 50 °C less than four sevenths of the sum of the marked test pressure plus 100 kPa;
or

(c) At 55 °C less than two thirds of the sum of the marked test pressure plus 100 kPa.

IBCs intended for the transport of liquids shall not be used to carry liquids having a vapour
pressure of more than 110 kPa (1.1 bar) at 50 °C or 130 kPa (1.3 bar) at 55 °C.

NOTE 1: For pure liquids the vapour pressure at 55 °C (Vp55) can often be obtained from scientific
tables.
NOTE 2: The table refers to the use of 4.1.1.10 (c) only, which means that the marked test pressure
shall exceed 1.5 times the vapour pressure at 55 °C less 100 kPa. When, for example, the test pressure for n-
decane is determined according to 6.1.5.5.4 (a), the minimum marked test pressure may be lower.
NOTE 3: For diethyl ether the required minimum test pressure under 6.1.5.5.5 is 250 kPa.

4.1.1.11 Empty packagings, including IBCs and large packagings, that have contained a dangerous
substance shall be treated in the same manner as is required by these Regulations for a filled packaging,
unless adequate measures have been taken to nullify any hazard.

4.1.1.12 Every packaging as specified in Chapter 6.1 intended to contain liquids shall successfully
undergo a suitable leakproofness test, and be capable of meeting the appropriate test level indicated
in 6.1.5.4.3:

(a) Before it is first used for transport;

(b) After remanufacturing or reconditioning of any packaging, before it is re-used for
transport.

For this test the packaging need not have its closures fitted. The inner receptacle of a
composite packaging may be tested without the outer packaging, provided the test results are not affected.
This test is not necessary for inner packagings of combination packagings or large packagings.

4.1.1.13 Packagings, including IBCs, used for solids which may become liquid at temperatures likely
to be encountered during transport shall also be capable of containing the substance in the liquid state.

4.1.1.14 Packagings, including IBCs, used for powdery or granular substances shall be siftproof or
shall be provided with a liner.

4.1.1.15 For plastics drums and jerricans, rigid plastics IBCs and composite IBCs with plastics inner
receptacles, unless otherwise approved by the competent authority, the period of use permitted for the
transport of dangerous substances shall be five years from the date of manufacture of the receptacles, except
where a shorter period of use is prescribed because of the nature of the substance to be transported.

4.1.1.16 Explosives, self-reactive substances and organic peroxides

Unless specific provision to the contrary is made in these Regulations, the packagings,
including IBCs and large packagings, used for goods of Class 1, self-reactive substances of Division 4.1 and
organic peroxides of Division 5.2 shall comply with the provisions for the medium danger group
(packing group II).
-8-


4.1.1.17 Use of salvage packagings

4.1.1.17.1 Damaged, defective, leaking or non-conforming packages, or dangerous goods that have
spilled or leaked may be transported in salvage packagings mentioned in 6.1.5.1.11. This does not prevent
the use of a bigger size packaging of appropriate type and performance level under the conditions
of 4.1.1.17.2.

4.1.1.17.2 Appropriate measures shall be taken to prevent excessive movement of the damaged or
leaking packages within a salvage packaging. When the salvage packaging contains liquids, sufficient inert
absorbent material shall be added to eliminate the presence of free liquid.

4.1.1.17.3 Appropriate measures shall be taken to ensure that there is no dangerous build up of
pressure.

4.1.2 Additional general provisions for the use of IBCs

4.1.2.1 When IBCs are used for the transport of liquids with a flash point of 60 °C (closed-cup) or
lower, or of powders liable to dust explosion, measures shall be taken to prevent a dangerous electrostatic
discharge.

4.1.2.2 Every metal, rigid plastics and composite IBC shall be inspected and tested, as relevant, in
accordance with 6.5.4.4 or 6.5.4.5:

- Before it is put into service;

- Thereafter at intervals not exceeding two and a half and five years, as appropriate; and

- After the repair or remanufacture, before it is re-used for transport.

An IBC shall not be filled and offered for transport after the date of expiry of the last
periodic test or inspection. However, an IBC filled prior to the date of expiry of the last periodic test or
inspection may be transported for a period not to exceed three months beyond the date of expiry of the last
periodic test or inspection. In addition, an IBC may be transported after the date of expiry of the last periodic
test or inspection:

(a) After emptying but before cleaning, for purposes of performing the required test or
inspection prior to refilling; and

(b) Unless otherwise approved by the competent authority, for a period not to exceed six
months beyond the date of expiry of the last periodic test or inspection in order to
allow the return of dangerous goods or residues for proper disposal or recycling.
Reference to this exemption shall be entered in the transport document.

4.1.2.3 IBCs of type 31HZ2 shall be filled to at least 80% of the volume of the outer casing and
always be carried in closed cargo transport units.

4.1.2.4 Except for routine maintenance of metal, rigid plastics, composite and flexible IBCs
performed by the owner of the IBC, whose State and name or authorized symbol is durably marked on the
IBC, the party performing routine maintenance shall durably mark the IBC near the manufacturer's
UN design type marking to show:

(a) The State in which the routine maintenance was carried out; and

(b) The name or authorized symbol of the party performing the routine maintenance.

4.1.3 General provisions concerning packing instructions

4.1.3.1 Packing instructions applicable to dangerous goods of Classes 1 to 9 are specified in 4.1.4.
They are subdivided depending on the type of packagings to which they apply:

4.1.4.1 for packagings other than IBCs and large packagings; these packing instructions
are designated by an alphanumeric code comprising the letter “P”;

4.1.4.2 for IBCs; these are designated by an alphanumeric code comprising the letters
“IBC”;

4.1.4.3 for large packagings; these are designated by an alphanumeric code comprising
the letters “LP”.

Generally, packing instructions specify that the general provisions of 4.1.1, 4.1.2 and/or
4.1.3, as appropriate, are applicable. They may also require compliance with the special provisions of
sections 4.1.5, 4.1.6, 4.1.7, 4.1.8 or 4.1.9 when appropriate. Special packing provisions may also be specified
in the packing instruction for individual substances or articles. They are also designated by an alphanumeric
code comprising the letters:

“PP” for packagings other than IBCs and large packagings
“B” for IBCs
“L” for large packagings.

Unless otherwise specified, each packaging shall conform to the applicable requirements of
Part 6. Generally packing instructions do not provide guidance on compatibility and the user should not
select a packaging without checking that the substance is compatible with the packaging material selected
(e.g. most fluorides are unsuitable for glass receptacles). Where glass receptacles are permitted in the
packing instructions porcelain, earthenware and stoneware packagings are also allowed.

4.1.3.2 Column 8 of the dangerous goods list shows for each article or substance the packing
instruction(s) that shall be used. Column 9 indicates the special packing provisions applicable to specific
substances or articles.

4.1.3.3 Each packing instruction shows, where applicable, the acceptable single and combination
packagings. For combination packagings, the acceptable outer packagings, inner packagings and when
applicable the maximum quantity permitted in each inner or outer packaging, are shown. Maximum net mass
and maximum capacity are as defined in 1.2.1.

4.1.3.4 The following packagings shall not be used when the substances being transported are liable
to become liquid during transport:

Packagings

Drums: 1D and 1G

13M1 and 13M2
Composite: 11HZ2 and 21HZ2.

4.1.3.5 Where the packing instructions in this chapter authorize the use of a particular type of
packaging (e.g. 4G; 1A2), packagings bearing the same packaging identification code followed by the letters
“V”, “U” or “W” marked in accordance with the requirements of Part 6 (e.g. 4GV, 4GU or 4GW; 1A2V,
1A2U or 1A2W) may also be used under the same conditions and limitations applicable to the use of that
type of packaging according to the relevant packing instructions. For example, a combination packaging
marked with the packaging code “4GV” may be used whenever a combination packaging marked “4G” is
authorized, provided the requirements in the relevant packing instruction regarding types of inner packagings
and quantity limitations are respected.

4.1.3.6 Pressure receptacles for liquids and solids

4.1.3.6.1 Unless otherwise indicated in these Regulations, pressure receptacles conforming to:

(a) The applicable requirements of Chapter 6.2; or

(b) The national or international standards on the design, construction, testing,
manufacturing and inspection, as applied by the country in which the pressure
receptacles are manufactured, provided that the provisions of 4.1.3.6 and 6.2.3.3 are
met;

are authorized for the transport of any liquid or solid substance other than explosives,
thermally unstable substances, organic peroxides, self-reactive substances, substances where significant
pressure may develop by evolution of chemical reaction and radioactive material (unless permitted in 4.1.9).

This sub-section is not applicable to the substances mentioned in 4.1.4.1, packing instruction
P200, Table 3.

4.1.3.6.2 Every design type of pressure receptacle shall be approved by the competent authority of the
country of manufacture or as indicated in Chapter 6.2.

4.1.3.6.3 Unless otherwise indicated, pressure receptacles having a minimum test pressure of 0.6 MPa
shall be used.

4.1.3.6.4 Unless otherwise indicated, pressure receptacles may be provided with an emergency
pressure relief device designed to avoid bursting in case of overfill or fire accidents.

Pressure receptacle valves shall be designed and constructed in such a way that they are
inherently able to withstand damage without release of the contents or shall be protected from damage which
could cause inadvertent release of the contents of the pressure receptacle, by one of the methods as given in
4.1.6.1.8 (a) to (e).

4.1.3.6.5 The level of filling shall not exceed 95% of the capacity of the pressure receptacle at 50 °C.
Sufficient ullage (outage) shall be left to ensure that the pressure receptacle will not be liquid full at a
temperature of 55 °C.
- 11 -


4.1.3.6.6 Unless otherwise indicated pressure receptacles shall be subjected to a periodic inspection
and test every 5 years. The periodic inspection shall include an external examination, an internal examination
or alternative method as approved by the competent authority, a pressure test or equivalent effective non-
destructive testing with the agreement of the competent authority including an inspection of all accessories
(e.g. tightness of valves, emergency relief valves or fusible elements). Pressure receptacles shall not be filled
after they become due for periodic inspection and test but may be transported after the expiry of the time
limit. Pressure receptacle repairs shall meet the requirements of 4.1.6.1.11.

4.1.3.6.7 Prior to filling, the filler shall perform an inspection of the pressure receptacle and ensure
that the pressure receptacle is authorized for the substances to be transported and that the provisions of these
Regulations have been met. Shut-off valves shall be closed after filling and remain closed during transport.
The consignor shall verify that the closures and equipment are not leaking.

4.1.3.6.8 Refillable pressure receptacles shall not be filled with a substance different from that
previously contained unless the necessary operations for change of service have been performed.

4.1.3.6.9 Marking of pressure receptacles for liquids and solids according to 4.1.3.6 (not conforming
to the requirements of Chapter 6.2) shall be in accordance with the requirements of the competent authority
of the country of manufacturing.

4.1.3.7 Packagings or IBCs not specifically authorized in the applicable packing instruction shall not
be used for the transport of a substance or article unless specifically approved by the competent authority and
provided:

(a) The alternative packaging complies with the general requirements of this Part;

(b) When the packing instruction indicated in the Dangerous Goods List so specifies, the
alternative packaging meets the requirements of Part 6;

(c) The competent authority determines that the alternative packaging provides at least the
same level of safety as if the substance were packed in accordance with a method
specified in the particular packing instruction indicated in the Dangerous Goods List;
and

(d) A copy of the competent authority approval accompanies each consignment or the
transport document includes an indication that alternative packaging was approved by
the competent authority.

NOTE: The competent authorities granting such approvals should take action to amend these Model
Regulations to include the provisions covered by the approval as appropriate.

4.1.3.8 Unpackaged articles other than Class 1 articles

4.1.3.8.1 Where large and robust articles cannot be packaged in accordance with the requirements of
Chapters 6.1 or 6.6 and they have to be transported empty, uncleaned and unpackaged, the competent
authority may approve such transport. In doing so the competent authority shall take into account that:

(a) Large and robust articles shall be strong enough to withstand the shocks and loadings
normally encountered during transport including trans-shipment between cargo
transport units and between cargo transport units and warehouses, as well as any
removal from a pallet for subsequent manual or mechanical handling;

(b) All closures and openings shall be sealed so that there can be no loss of contents
which might be caused under normal conditions of transport, by vibration, or by
changes in temperature, humidity or pressure (resulting from altitude, for example).
No dangerous residue shall adhere to the outside of the large and robust articles;
- 12 -


(c) Parts of large and robust articles, which are in direct contact with dangerous goods:

(i) shall not be affected or significantly weakened by those dangerous goods; and

(ii) shall not cause a dangerous effect e.g. catalysing a reaction or reacting with the
dangerous goods;

(d) Large and robust articles containing liquids shall be stowed and secured to ensure that
neither leakage nor permanent distortion of the article occurs during transport;

(e) They shall be fixed in cradles or crates or other handling devices in such a way that
they will not become loose during normal conditions of transport.

4.1.3.8.2 Unpackaged articles approved by the competent authority in accordance with the provisions
of 4.1.3.8.1 shall be subject to the consignment procedures of Part 5. In addition the consignor of such
articles shall ensure that a copy of any such approval is transported with the large and robust articles.

general requirements of 4.2.4 shall be met.

Cylinders, tubes, pressure drums, bundles of cylinders constructed as specified in Chapter 6.2 and MEGCs
constructed as specified in 6.7.5 are authorised for the transport of a specific substance when specified in the
following tables. For some substances the special packing provisions may prohibit a particular type of cylinder, tube,
pressure drum or bundle of cylinders.

(1) Pressure receptacles containing toxic substances with an LC50 less than or equal to 200 ml/m3 (ppm) as
specified in the table shall not be equipped with any pressure relief device. Pressure relief devices shall be
fitted on pressure receptacles used for the transport of UN 1013 carbon dioxide and UN 1070 nitrous

authority of the country of use. The type of pressure relief device, the set to discharge pressure and relief
capacity of pressure relief devices, if required, shall be specified by the competent authority of the country
of use.
(2) The following three tables cover compressed gases (Table 1), liquefied and dissolved gases (Table 2) and
substances not in Class 2 (Table 3). They provide:
(a) the UN number, name and description, and classification of the substance;
(b) the LC50 for toxic substances;
(c) the types of pressure receptacles authorised for the substance, shown by the letter “X”;

(d) the maximum test period for periodic inspection of the pressure receptacles;
NOTE: For pressure receptacles which make use of composite materials, the periodic inspection
frequencies shall be as determined by the competent authority which approved the receptacles.
(e) the minimum test pressure of the pressure receptacles;
(f) the maximum working pressure of the pressure receptacles for compressed gases (where no value is
given, the working pressure shall not exceed two thirds of the test pressure) or the maximum filling
ratio(s) dependent on the test pressure(s) for liquefied and dissolved gases;
(g) special packing provisions that are specific to a substance.
(3) In no case shall pressure receptacles be filled in excess of the limit permitted in the following
requirements.
(a) For compressed gases, the working pressure shall be not more than two thirds of the test pressure of
the pressure receptacles. Restrictions to this upper limit on working pressure are imposed by (4),
special packing provision “o”. In no case shall the internal pressure at 65 °C exceed the test
pressure;
(b) For high pressure liquefied gases, the filling ratio shall be such that the settled pressure at 65 °C
does not exceed the test pressure of the pressure receptacles.

The use of test pressures and filling ratios other than those in the table is permitted, except
where (4), special packing provision “o” applies, provided that:
(i) the criterion of (4), special packing provision “r” is met when applicable; or
(ii) the above criterion is met in all other cases.
For high pressure liquefied gases and gas mixtures for which relevant data are not available, the
maximum filling ratio (FR) shall be determined as follows:

FR = 8.5 ×10-4 × dg × Ph
where FR = maximum filling ratio
dg = gas density (at 15 °C, 1 bar)(in g/l)
Ph = minimum test pressure (in bar)

Cont'd on next page

- 38 -


P200 PACKING INSTRUCTION (cont'd) P200
If the density of the gas is unknown, the maximum filling ratio shall be determined as follows:
Ph × MM × 10 −3
FR =
R × 338
Ph = minimum test pressure (in bar)
MM = molecular mass (in g/mol)
R = 8.31451 × 10-2 bar.l/mol.K (gas constant)

For gas mixtures, the average molecular mass is to be taken, taking into account the volumetric
concentrations of the various components;
(c) For low pressure liquefied gases, the maximum mass of contents per litre of water capacity (filling
factor) shall equal 0.95 times the density of the liquid phase at 50 °C; in addition, the liquid phase
shall not fill the pressure receptacle at any temperature up to 60 °C. The test pressure of the
pressure receptacle shall be at least equal to the vapour pressure (absolute) of the liquid at 65 °C,
minus 100 kPa (1 bar).
For low pressure liquefied gases and gas mixtures for which relevant data are not available, the
maximum filling ratio shall be determined as follows:
FR = (0.0032 × BP – 0.24) × d1
BP = boiling point (in Kelvin)
d1 = density of the liquid at boiling point (in kg/l);
(d) For UN 1001, acetylene, dissolved, and UN 3374 acetylene, solvent free, see (4), special packing
provision “p”.

1.3 times the sum of the maximum internal pressure of the filled receptacle, including during filling and
discharge, plus 100 kPa (1 bar);
(b) For other closed cryogenic receptacles, the test pressure shall be not less than 1.3 times the maximum
internal pressure of the filled receptacle, taking into account the pressure developed during filling and
discharge.
(5) Degree of filling
For non-flammable, non-toxic refrigerated liquefied gases the volume of liquid phase at the filling temperature
and at a pressure of 100 kPa (1 bar) shall not exceed 98% of the water capacity of the pressure receptacle.
For flammable refrigerated liquefied gases the degree of filling shall remain below the level at which, if the
contents were raised to the temperature at which the vapour pressure equalled the opening pressure of the relief
valve, the volume of the liquid phase would reach 98% of the water capacity at that temperature.
(6) Pressure-relief devices
Closed cryogenic receptacles shall be fitted with at least one pressure-relief device.
(7) Compatibility
Materials used to ensure the leakproofness of the joints or for the maintenance of the closures shall be
compatible with the contents. In the case of receptacles intended for the transport of oxidizing gases (i.e. with a
subsidiary risk of 5.1), these materials shall not react with these gases in a dangerous manner.
Requirements for open cryogenic receptacles:

conditions, including fatigue, to which they will be subjected during their normal use and during normal
conditions of transport.
(2) The capacity shall be not more than 450 litres.
(3) The receptacle shall have a double wall construction with the space between the inner and outer wall being
evacuated (vacuum insulation). The insulation shall prevent the formation of hoar frost on the exterior of the
receptacle.
(4) The materials of construction shall have suitable mechanical properties at the service temperature.
(5) Materials which are in direct contact with the dangerous goods shall not be affected or weakened by the
dangerous goods intended to be transported and shall not cause a dangerous effect, e.g. catalysing a reaction or
reacting with the dangerous goods.
(6) Receptacles of glass double wall construction shall have an outer packaging with suitable cushioning or
absorbent materials which withstand the pressures and impacts liable to occur under normal conditions
of transport.
(7) The receptacle shall be designed to remain in an upright position during transport, e.g. have a base whose
smaller horizontal dimension is greater than the height of the centre of gravity when filled to capacity or be
mounted on gimbals.
(8) The openings of the receptacles shall be fitted with devices allowing gases to escape, preventing any splashing
out of liquid, and so configured that they remain in place during transport.
(9) Open cryogenic receptacles shall bear the following marks permanently affixed e.g. by stamping, engraving or
etching:
- The manufacturer’s name and address;
- The model number or name;
- The serial or batch number;
- The UN number and proper shipping name of gases for which the receptacle is intended;
- The capacity of the receptacle in litres.

CHAPTER 4.2

USE OF PORTABLE TANKS AND
MULTIPLE-ELEMENT GAS CONTAINERS (MEGCs)

4.2.1 General provisions for the use of portable tanks for the transport of substances of
Class 1 and Classes 3 to 9

4.2.1.1 This section provides general requirements applicable to the use of portable tanks for the
transport of substances of Classes 1, 3, 4, 5, 6, 7, 8 and 9. In addition to these general requirements, portable
tanks shall conform to the design, construction, inspection and testing requirements detailed in 6.7.2.
Substances shall be transported in portable tanks conforming to the applicable portable tank instruction
identified in Column 10 of the Dangerous Goods List and described in 4.2.5.2.6 (T1 to T23) and the portable
tank special provisions assigned to each substance in Column 11 of the Dangerous Goods List and described
in 4.2.5.3.

4.2.1.2 During transport, portable tanks shall be adequately protected against damage to the shell
and service equipment resulting from lateral and longitudinal impact and overturning. If the shell and service
equipment are so constructed as to withstand impact or overturning it need not be protected in this way.
Examples of such protection are given in 6.7.2.17.5.

4.2.1.3 Certain substances are chemically unstable. They are accepted for transport only when the
necessary steps have been taken to prevent their dangerous decomposition, transformation or polymerization
during transport. To this end, care shall in particular be taken to ensure that shells do not contain any
substances liable to promote these reactions.

4.2.1.4 The temperature of the outer surface of the shell excluding openings and their closures or of
the thermal insulation shall not exceed 70 °C during transport. When necessary, the shell shall be thermally
insulated.

4.2.1.5 Empty portable tanks not cleaned and not gas-free shall comply with the same requirements
as portable tanks filled with the previous substance.

4.2.1.6 Substances shall not be transported in the same or adjoining compartments of shells when
they may react dangerously with each other and cause:

(a) Combustion and/or evolution of considerable heat;

(b) Evolution of flammable, toxic or asphyxiant gases;

(c) The formation of corrosive substances;

(d) The formation of unstable substances;

(e) Dangerous rise in pressure.

4.2.1.7 The design approval certificate, the test report and the certificate showing the results of the
initial inspection and test for each portable tank issued by the competent authority or its authorized body
shall be retained by the authority or body and the owner. Owners shall be able to provide this documentation
upon the request of any competent authority.

4.2.1.8 Unless the name of the substance(s) being transported appears on the metal plate described
in 6.7.2.20.2, a copy of the certificate specified in 6.7.2.18.1 shall be made available upon the request of a
competent authority or its authorized body and readily provided by the consignor, consignee or agent, as
appropriate.
- 99 -


4.2.1.9 Degree of Filling

4.2.1.9.1 Prior to filling, the consignor shall ensure that the appropriate portable tank is used and that
the portable tank is not loaded with substances which in contact with the materials of the shell, gaskets,
service equipment and any protective linings, are likely to react dangerously with them to form dangerous
products or appreciably weaken these materials. The consignor may need to consult the manufacturer of the
substance in conjunction with the competent authority for guidance on the compatibility of the substance
with the portable tank materials.

4.2.1.9.1.1 Portable tanks shall not be filled above the extent provided in 4.2.1.9.2 to 4.2.1.9.6. The
applicability of 4.2.1.9.2, 4.2.1.9.3 or 4.2.1.9.5.1 to individual substances is specified in the applicable
portable tank instructions or special provisions in 4.2.5.2.6 or 4.2.5.3 and Columns 10 or 11 of the
Dangerous Goods List.

4.2.1.9.2 The maximum degree of filling (in %) for general use is determined by the formula:

97
Degree of filling =
1 + α (t r - t f )

4.2.1.9.3 The maximum degree of filling (in %) for liquids of Division 6.1 and Class 8, in packing
groups I and II, and liquids with an absolute vapour pressure of more than 175 kPa (1.75 bar) at 65 °C, is
determined by the formula:

95
Degree of filling =
1 + α (t r - t f )

4.2.1.9.4 In these formulae, α is the mean coefficient of cubical expansion of the liquid between the
mean temperature of the liquid during filling (tf) and the maximum mean bulk temperature during
transport (tr) (both in °C). For liquids transported under ambient conditions α could be calculated by the
formula:

d15 − d 50
α=
35d 50

in which d15 and d50 are the densities of the liquid at 15 °C and 50 °C, respectively.

4.2.1.9.4.1 The maximum mean bulk temperature (tr) shall be taken as 50 °C except that, for journeys
under temperate or extreme climatic conditions, the competent authorities concerned may agree to a lower or
require a higher temperature, as appropriate.

4.2.1.9.5 The requirements of 4.2.1.9.2 to 4.2.1.9.4.1 do not apply to portable tanks which contain
substances maintained at a temperature above 50 °C during transport (e.g. by means of a heating device). For
portable tanks equipped with a heating device, a temperature regulator shall be used to ensure the maximum
degree of filling is not more than 95% full at any time during transport.

4.2.1.9.5.1 The maximum degree of filling (in %) for solids transported above their melting points and
for elevated temperature liquids shall be determined by the following formula:

dr
Degree of filling = 95
df
in which df and dr are the densities of the liquid at the mean temperature of the liquid during filling and the
maximum mean bulk temperature during transport respectively.

- 100 -


4.2.1.9.6 Portable tanks shall not be offered for transport:

(a) With a degree of filling, for liquids having a viscosity less than 2,680 mm2/s at 20 °C
or maximum temperature of the substance during transport in the case of the heated
substance, of more than 20% but less than 80% unless the shells of portable tanks are
divided, by partitions or surge plates, into sections of not more than 7,500 litres
capacity;

(b) With residue of substances previously transported adhering to the outside of the shell
or service equipment;

(c) When leaking or damaged to such an extent that the integrity of the portable tank or its
lifting or securing arrangements may be affected; and

(d) Unless the service equipment has been examined and found to be in good working
order.

4.2.1.9.7 Forklift pockets of portable tanks shall be closed off when the tank is filled. This provision
does not apply to portable tanks which according to 6.7.2.17.4 need not be provided with a means of closing
off the forklift pockets.

CHAPTER 4.3

USE OF BULK CONTAINERS

4.3.1 General provisions

4.3.1.1 This section provides general requirements applicable to the use of containers for the
transport of solid substances in bulk. Substances shall be transported in bulk containers conforming to the
applicable bulk container instruction identified by the letters BK in Column 10 of the Dangerous Goods List,
with the following meaning:

BK1: the transport in sheeted bulk containers is permitted
BK2: the transport in closed bulk containers is permitted

The bulk container used shall conform to the requirements of Chapter 6.8.

4.3.1.2 Except as provided in 4.3.1.3, bulk containers shall only be used when a substance is
assigned to a bulk container code in Column 10 of the Dangerous Goods List in Chapter 3.2.

4.3.1.3 When a substance is not assigned a bulk container code in Column 10 of the Dangerous
Goods List in Chapter 3.2, interim approval for transport may be issued by the competent authority of the
country of origin. The approval shall be included in the documentation of the consignment and contain, as a
minimum, the information normally provided in the bulk container instruction and the conditions under
which the substance shall be transported. Appropriate measures should be initiated by the competent
authority to include the assignment in the Dangerous Goods List.

4.3.1.4 Substances which may become liquid at temperatures likely to be encountered during
transport, are not permitted in bulk containers.

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

4.3.1.6 Bulk solids shall be loaded into bulk containers and evenly distributed in a manner that
minimises movement that could result in damage to the container or leakage of the dangerous goods.

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

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

4.3.1.9 Before being filled and offered for transport each bulk container shall be inspected and
cleaned to ensure that it does not contain any residue on the interior or exterior of the bulk container that
could:

- cause a dangerous reaction with the substance intended for transport;

- detrimentally affect the structural integrity of the bulk container; or

- affect the dangerous goods retention capabilities of the bulk container.

- 123 -


4.3.1.10 During transport, no dangerous residues shall adhere to the outer surfaces of bulk containers.

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

4.3.1.12 Empty bulk containers that have contained a dangerous substance shall be treated in the
same manner as is required by these Regulations for a filled bulk container, unless adequate measures have
been taken to nullify any hazard.

4.3.1.13 If bulk containers are used for the transport of bulk 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 transport filling or discharge of the substance.

4.3.1.14 Substances, for example wastes, which may react dangerously with one another and
substances of different classes and goods not subject to these Regulations, which are liable to react
dangerously with one another shall not be mixed together in the same bulk container. 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.

4.3.1.15 Before a bulk container 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 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 freight container. Major defects include:

(a) Bends, cracks or breaks in the structural or supporting members that affect the
integrity of the container;

(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 great enough to prevent proper alignment
of handling equipment, mounting and securing chassis or vehicle, or insertion into
ships' cells;

(h) Any damage to lifting attachments or handling equipment interface features; or

(i) Any damage to service or operational equipment.
