Dangerous Goods by Road
All packagings for Class 1 goods shall be so designed and constructed that:
(a) They will protect the explosives, prevent them escaping and cause no increase in the risk of
unintended ignition or initiation when subjected to normal conditions of carriage including
foreseeable changes in temperature, humidity and pressure;
(b) The complete package can be handled safely in normal conditions of carriage; and
(c) The packages will withstand any loading imposed on them by foreseeable stacking to which
they will be subject during carriage so that they do not add to the risk presented by the
explosives, the containment function of the packagings is not harmed, and they are not
distorted in a way or to an extent which will reduce their strength or cause instability of a stack.
All explosive substances and articles, as prepared for carriage, shall have been classified in
accordance with the procedures detailed in 2.2.1.
Class 1 goods shall be packed in accordance with the appropriate packing instruction shown in
Column (8) of Table A of Chapter 3.2, as detailed in 4.1.4.
Unless otherwise specified in ADR, packagings, including IBCs and large packagings, shall conform
to the requirements of chapters 6.1, 6.5 or 6.6, as appropriate, and shall meet their test requirements
for packing group II.
The closure device of packagings containing liquid explosives shall ensure a double protection against
leakage.
The closure device of metal drums shall include a suitable gasket; if a closure device includes a screwthread,
the ingress of explosive substances into the screw-thread shall be prevented.
Packagings for water soluble substances shall be water resistant. Packagings for desensitized or
phlegmatized substances shall be closed to prevent changes in concentration during carriage.
When the packaging includes a double envelope filled with water which may freeze during transport,
a sufficient quantity of an anti-freeze agent shall be added to the water to prevent freezing. Anti-freeze
that could create a fire hazard because of its inherent flammability shall not be used.
Nails, staples and other closure devices made of metal without protective covering shall not penetrate
to the inside of the outer packaging unless the inner packaging adequately protects the explosives
against contact with the metal.
Inner packagings, fittings and cushioning materials and the placing of explosive substances or articles
in packages shall be accomplished in a manner which prevents the explosive substances or articles
from becoming loose in the outer packaging under normal conditions of carriage. Metallic
components of articles shall be prevented from making contact with metal packagings. Articles
containing explosive substances not enclosed in an outer casing shall be separated from each other in
order to prevent friction and impact. Padding, trays, partitioning in the inner or outer packaging,
mouldings or receptacles may be used for this purpose.
Packagings shall be made of materials compatible with, and impermeable to, the explosives contained
in the package, so that neither interaction between the explosives and the packaging materials, nor
leakage, causes the explosive to become unsafe to carriage, or the hazard division or compatibility
group to change.
The ingress of explosive substances into the recesses of seamed metal packagings shall be prevented.
Plastics packagings shall not be liable to generate or accumulate sufficient static electricity so that a
discharge could cause the packaged explosive substances or articles to initiate, ignite or function.
Large and robust explosives articles, normally intended for military use, without their means of
initiation or with their means of initiation containing at least two effective protective features, may be
carried unpackaged. When such articles have propelling charges or are self-propelled, their ignition
systems shall be protected against stimuli encountered during normal conditions of carriage. A
negative result in Test Series 4 on an unpackaged article indicates that the article can be considered
for carriage unpackaged. Such unpackaged articles may be fixed to cradles or contained in crates or
other suitable handling, storage or launching devices in such a way that they will not become loose
during normal conditions of carriage.
Where such large explosive articles are as part of their operational safety and suitability tests
subjected to test regimes that meet the intentions of ADR and such tests have been successfully
undertaken, the competent authority may approve such articles to be carried in accordance with ADR.
Explosive substances shall not be packed in inner or outer packagings where the differences in
internal and external pressures, due to thermal or other effects, could cause an explosion or rupture of
the package.
