The security plan shall comprise at least the following elements:
(a) Specific allocation of responsibilities for security to competent and qualified persons with
appropriate authority to carry out their responsibilities;
(b) Records of dangerous goods or types of dangerous goods concerned;
(c) Review of current operations and assessment of security risks, including any stops necessary to
the transport operation, the keeping of dangerous goods in the vehicle, tank or container before,
during and after the journey and the intermediate temporary storage of dangerous goods during
the course of intermodal transfer or transhipment between units as appropriate;
(d) Clear statement of measures that are to be taken to reduce security risks, commensurate with
the responsibilities and duties of the participant, including:
- security policies (e.g. response to higher threat conditions, new employee/employment
- operating practices (e.g. choice/use of routes where known, access to dangerous goods
in intermediate temporary storage (as defined in (c)), proximity to vulnerable
- equipment and resources that are to be used to reduce security risks;
(e) Effective and up to date procedures for reporting and dealing with security threats, breaches of
security or security incidents;
(f) Procedures for the evaluation and testing of security plans and procedures for periodic review
and update of the plans;
(g) Measures to ensure the physical security of transport information contained in the security
(h) Measures to ensure that the distribution of information relating to the transport operation
contained in the security plan is limited to those who need to have it. Such measures shall not
preclude the provision of information required elsewhere in ADR.
NOTE: Carriers, consignors and consignees should co-operate with each other and with competent
authorities to exchange threat information, apply appropriate security measures and respond to
Devices, equipment or arrangements to prevent the theft of the vehicle carrying high consequence
dangerous goods (see Table 188.8.131.52.2) or high consequence radioactive material (see 184.108.40.206.3) and
its cargo, shall be applied and measures taken to ensure that these are operational and effective at all
times. The application of these protective measures shall not jeopardize emergency response.
NOTE: When appropriate and already fitted, the use of transport telemetry or other tracking
methods or devices should be used to monitor the movement of high consequence dangerous goods
(see Table 220.127.116.11.2) or high consequence radioactive material (see 18.104.22.168.3).
In accordance with the provisions of 22.214.171.124, the requirements of 1.10.1, 1.10.2, 1.10.3 and 126.96.36.199 (d)
do not apply when the quantities carried in packages on a transport unit do not exceed those referred
to in 188.8.131.52.3, except for UN Nos. 0029, 0030, 0059, 0065, 0073, 0104, 0237, 0255, 0267, 0288,
0289, 0290, 0360, 0361, 0364, 0365, 0366, 0439, 0440, 0441, 0455, 0456 and 0500 and except for
UN Nos. 2910 and 2911 if the activity level exceeds the A2 value (see first indent of 184.108.40.206.2). In
addition, the requirements of 1.10.1, 1.10.2, 1.10.3 and 220.127.116.11 (d) do not apply when the quantities
carried in tanks or in bulk on a transport unit do not exceed those referred to in 18.104.22.168.3. In addition
the provisions of this Chapter do not apply to the carriage of UN No. 2912 RADIOACTIVE
MATERIAL, LOW SPECIFIC ACTIVITY (LSA-I) and UN No. 2913 RADIOACTIVE MATERIAL,
SURFACE CONTAMINATED OBJECTS (SCO-I).
For radioactive material, the provisions of this Chapter are deemed to be complied with when the
provisions of the Convention on Physical Protection of Nuclear Material1 and the IAEA circular on
"The Physical Protection of Nuclear Material and Nuclear Facilities"2 are applied.
The classes of dangerous goods according to ADR are the following:
Class 1 Explosive substances and articles
Class 2 Gases
Class 3 Flammable liquids
Class 4.1 Flammable solids, self-reactive substances, polymerizing substances and solid
Class 4.2 Substances liable to spontaneous combustion
Class 4.3 Substances which, in contact with water, emit flammable gases
Class 5.1 Oxidizing substances
Class 5.2 Organic peroxides
Class 6.1 Toxic substances
Class 6.2 Infectious substances
Class 7 Radioactive material
Class 8 Corrosive substances
Class 9 Miscellaneous dangerous substances and articles
Each entry in the different classes has been assigned a UN number. The following types of entries are
A. Single entries for well defined substances or articles including entries for substances covering
several isomers, e.g.:
UN No. 1090 ACETONE
UN No. 1104 AMYL ACETATES
UN No. 1194 ETHYL NITRITE SOLUTION
B. Generic entries for a well defined group of substances or articles, which are not n.o.s. entries,
UN No. 1133 ADHESIVES
UN No. 1266 PERFUMERY PRODUCTS
UN No. 2757 CARBAMATE PESTICIDE, SOLID, TOXIC
UN No. 3101 ORGANIC PEROXIDE TYPE B, LIQUID
C. Specific n.o.s. entries covering a group of substances or articles of a particular chemical or
technical nature, not otherwise specified, e.g.:
UN No. 1477 NITRATES, INORGANIC, N.O.S.
UN No. 1987 ALCOHOLS, N.O.S.
D. General n.o.s. entries covering a group of substances or articles having one or more dangerous
properties, not otherwise specified, e.g.:
UN No. 1325 FLAMMABLE SOLID, ORGANIC, N.O.S.
UN No. 1993 FLAMMABLE LIQUID, N.O.S.
The entries defined under B., C. and D. are defined as collective entries.
For packing purposes, substances other than those of Classes 1, 2, 5.2, 6.2 and 7, and other than selfreactive
substances of Class 4.1 are assigned to packing groups in accordance with the degree of
danger they present:
Packing group I: Substances presenting high danger;
Packing group II: Substances presenting medium danger;
Packing group III: Substances presenting low danger.
The packing group(s) to which a substance is assigned is (are) indicated in Table A of Chapter 3.2.
Articles are not assigned to packing groups. For packing purposes any requirement for a specific
packaging performance level is set out in the applicable packing instruction.
Principles of classification
The dangerous goods covered by the heading of a class are defined on the basis of their properties
according to sub-section 2.2.x.1 of the relevant class. Assignment of dangerous goods to a class and a
packing group is made according to the criteria mentioned in the same sub-section 2.2.x.1.
Assignment of one or several subsidiary risk(s) to a dangerous substance or article is made according
to the criteria of the class or classes corresponding to those risks, as mentioned in the appropriate subsection(
All dangerous goods entries are listed in Table A of Chapter 3.2 in the numerical order of their UN
Number. This table contains relevant information on the goods listed, such as name, class, packing
group(s), label(s) to be affixed, packing and carriage provisions1. The substances listed by name in
column (2) of Table A of Chapter 3.2 shall be carried according to their classification in Table A or
under the conditions specified in 22.214.171.124.
