“Chapter 1.5 – General provisions
concerning class 7
These provisions are satisfied firstly by applying a graded
approach to contents limits for packages and conveyances and to performance
standards applied to package designs depending upon the hazard of
the radioactive contents. Secondly, they are satisfied by imposing
requirements on the design and operation of packages and on the maintenance
of packagings, including a consideration of the nature of the radioactive
contents. Finally, they are satisfied by requiring administrative
controls including, where appropriate, approval by competent authorities.
1.5.1.3 The provisions of this Code apply to the
transport of radioactive material by sea including transport which
is incidental to the use of the radioactive material. Transport comprises
all operations and conditions associated with and involved in the
movement of radioactive material; these include the design, manufacture,
maintenance and repair of packaging, and the preparation, consigning,
loading, transport including in-transit storage, unloading and receipt
at the final destination of loads of radioactive material and packages.
A graded approach is applied to the performance standards in the provisions
of this Code that is characterized by three general severity levels:
-
.1 Routine conditions of transport (incident free);
-
.2 Normal conditions of transport (minor mishaps);
and
-
.3 Accident conditions of transport.
1.5.1.4 The provisions of this Code shall not
apply to:
-
.1 Radioactive material that is an integral part
of the means of transport;
-
.2 Radioactive material moved within an establishment
which is subject to appropriate safety regulations in force in the
establishment and where the movement does not involve public roads
or railways;
-
.3 Radioactive material implanted or incorporated
into a person or live animal for diagnosis or treatment;
-
.4 Radioactive material in consumer products which
have received regulatory approval, following their sale to the end
user;
-
.5 Natural material and ores containing naturally
occurring radionuclides which are either in their natural state, or
have only been processed for purposes other than for extraction of
the radionuclides, and which are not intended to be processed for
use of these radionuclides provided the activity concentration of
the material does not exceed 10 times the values specified in 2.7.2.2.1.2,
or calculated in accordance with 2.7.2.2.2 to 2.7.2.2.6; and
-
.6 Non-radioactive solid objects with radioactive
substances present on any surfaces in quantities not in excess of
the limit set out in the definition for “contamination”
in 2.7.1.2.
1.5.1.5 Specific provisions for the transport
of excepted packages
1.5.1.5.1 Excepted packages which may contain
radioactive material in limited quantities, instruments, manufactured
articles and empty packagings as specified in 2.7.2.4.1 may be transported
under the following conditions:
-
.1 The applicable provisions specified in 2.0.3.5,
2.7.2.4.1.2 to 2.7.2.4.1.6 (as applicable), 4.1.9.1.2, 5.2.1.1, 5.2.1.2,
5.2.1.5.1 to 5.2.1.5.3, 5.4.1.4.1.1 and 7.3.4.2;
-
.2 The provisions for excepted packages specified
in 6.4.4; and
-
.3 If the excepted package contains fissile material,
one of the fissile exceptions provided by 2.7.2.3.5 shall apply and
the provision of 6.4.7.2 shall be met.
1.5.1.5.2 The following provisions shall not apply
to excepted packages and the controls for transport of excepted packages:
1.4.2, 1.4.3, 2.7.2.3.3.1.1, 2.7.2.3.3.2, 4.1.9.1.3, 4.1.9.1.4, 4.1.9.1.6,
4.1.9.1.7, 5.1.3.2, 5.2.2.1.12.1, 5.4.1.5.7.1, 5.4.1.5.7.2, 5.4.1.6,
6.4.6.1, 7.1.14.11 to 7.1.14.14, 7.2.9.1, 7.2.9.2, 7.2.1 and 7.3.4.1.
1.5.1 Scope and application
1.5.1.1 The provisions of this Code establish
standards of safety which provide an acceptable level of control of
the radiation, criticality and thermal hazards to persons, property
and the environment that are associated with the transport of radioactive
material. These provisions are based on the IAEA Regulations for the
Safe Transport of Radioactive Material (2005 Edition), Safety Standards
Series No. TS-R-1, IAEA, Vienna (2005). Explanatory material on the
1996 edition of TS-R-1 can be found in “Advisory Material for
the IAEA Regulations for the Safe Transport of Radioactive Materialfootnote”, Safety Standard Series No. TS-G-1.1
(ST-2), IAEA, Vienna (2002).
1.5.1.2 The objective of the provisions of this
Code is to protect persons, property and the environment from the
effects of radiation during the transport of radioactive material.
This protection is achieved by requiring:
-
.1 Containment of the radioactive contents;
-
.2 Control of external radiation levels;
-
.3 Prevention of criticality; and
-
.4 Prevention of damage caused by heat.
1.5.2 Radiation protection programme
1.5.2.1 The transport of radioactive material
shall be subject to a radiation protection programme which shall consist
of systematic arrangements aimed at providing adequate consideration
of radiation protection measures.
1.5.2.2 Doses to persons shall be below the relevant
dose limits. Protection and safety shall be optimized in order that
the magnitude of individual doses, the number of persons exposed,
and the likelihood of incurring exposure shall be kept as low as reasonably
achievable, economic and social factors being taken into account,
within the restrictions that the doses to individual be subject to
dose constraints. A structured and systematic approach shall be adopted
and shall include consideration of the interfaces between transport
and other activities.
1.5.2.3 The nature and extent of the measures
to be employed in the programme shall be related to the magnitude
and likelihood of radiation exposures. The programme shall incorporate
the provisions in 1.5.2.2, 1.5.2.4 to 1.5.2.7. Programme documents
shall be available, on request, for inspection by the relevant competent
authority.
1.5.2.4 For occupational exposures arising from
transport activities, where it is assessed that the effective dose:
-
.1 is likely to be between 1 and 6 mSv in a year,
a dose assessment programme via workplace monitoring or individual
monitoring shall be conducted;
-
.2 is likely to exceed 6 mSv in a year, individual
monitoring shall be conducted.
When individual monitoring or workplace monitoring is conducted,
appropriate records shall be kept.
Note: For occupational exposures arising from transport
activities, where it is assessed that the effective dose is most unlikely
to exceed 1 mSv in a year, no special work patterns, detailed monitoring,
dose assessment programmes or individual record keeping need be required.
1.5.3 Quality assurance
1.5.3.1 Quality assurance programmes based on
international, national or other standards acceptable to the competent
authority shall be established and implemented for the design, manufacture,
testing, documentation, use, maintenance and inspection of all special
form radioactive material, low dispersible radioactive material and
packages and for transport and in-transit storage operations to ensure
compliance with the relevant provisions of this Code. Certification
that the design specification has been fully implemented shall be
available to the competent authority. The manufacturer, consignor
or user shall be prepared to provide facilities for competent authority
inspection during manufacture and use and to demonstrate to any cognizant
competent authority that:
-
.1 the manufacturing methods and materials used
are in accordance with the approved design specifications; and
-
.2 all packagings are periodically inspected and,
as necessary, repaired and maintained in good condition so that they
continue to comply with all relevant requirements and specifications,
even after repeated use.
Where competent authority approval is required, such approval
shall take into account and be contingent upon the adequacy of the
quality assurance programme.
1.5.4 Special arrangement
1.5.4.1 Special arrangement shall mean those provisions,
approved by the competent authority, under which consignments which
do not satisfy all the provisions of this Code applicable to radioactive
material may be transported.
1.5.4.2 Consignments for which conformity with
any provision applicable to class 7 is impracticable shall not be
transported except under special arrangement. Provided the competent
authority is satisfied that conformity with the class 7 provisions
of this Code is impracticable and that the requisite standards of
safety established by this Code have been demonstrated through alternative
means the competent authority may approve special arrangement transport
operations for single or a planned series of multiple consignments.
The overall level of safety in transport shall be at least equivalent
to that which would be provided if all the applicable provisions had
been met. For international consignments of this type, multilateral
approval shall be required.
1.5.5 Radioactive material possessing other dangerous
properties
1.5.5.1 In addition to the radioactive and fissile
properties, any subsidiary risk of the contents of a package, such
as explosiveness, flammability, pyrophoricity, chemical toxicity and
corrosiveness, shall also be taken into account in the documentation,
packing, labelling, marking, placarding, stowage, segregation and
transport, in order to be in compliance with all relevant provisions
for dangerous goods. (See also special provision 172 and, for excepted
packages, special provision 290.)
1.5.6 Non-compliance
1.5.6.1 In the event of a non-compliance with
any limit in the provisions of this Code applicable to radiation level
or contamination,
-
.1 The consignor shall be informed of the non-compliance
-
.2 The carrier, consignor or consignee, as appropriate,
shall:
-
(i) take immediate steps to mitigate the consequences
of the non-compliance;
-
(ii) investigate the non-compliance and its causes,
circumstances and consequences;
-
(iii) take appropriate action to remedy the causes
and circumstances that led to the non-compliance and to prevent a
recurrence of similar circumstances that led to the non-compliance;
and
-
(iv) communicate to the relevant competent authority(ies)
on the causes of the non-compliance and on corrective or preventive
actions taken or to be taken; and
-
.3 The communication of the non-compliance to
the consignor and relevant competent authority(ies), respectively,
shall be made as soon as practicable and it shall be immediate whenever
an emergency exposure situation has developed or is developing.”
