Classifying Dangerous Goods
 The shipper is responsible for correctly identifying and
classifying all dangerous goods including assigning the
correct hazard class and applicable packing group.
 Dangerous goods are defined as those goods which meet
the criteria of one or more of the nine UN hazard classes
and where applicable, to one of three UN Packing Groups.
 Hazard classes relate to the type of hazard
 Packing groups relate to the degree of hazard
 Articles are no longer assigned packing groups

Packing Groups and Performance
Level Packaging
 Substances are assigned to
packing groups based on the
degree of danger they present
for packing purposes.
Packing Group
Degree of
Danger
I High Danger
II Medium Danger
III Low Danger
4

Packing Groups and Performance
Level Packaging
 UN Specification packaging must meet the performance
level requirements of the assigned packing group
 Performance level packaging for articles is specified in the
packing instruction assigned to the article
Packing Group Performance Level
I X
II Y
III Z

DGR Classification System
 The physical state and physical properties of the dangerous
goods will affect how easily and safety the goods can be
handled in transport, how they should be packaged and
what hazards they present, especially if spilled.

DGR Classification System
 The DGR also divides dangerous goods into:
Substances Articles
7

General Principles
 Dangerous Goods are divided into 9 hazard groups called
classes.
 Classes 1, 2, 4, 5 and 6 are broken down into “Divisions”
due to hazard variation within these classes.
 Classes are expressed by single-digit numbers.
 Example: Class 7
 Divisions are expressed by 2-digit numbers. The first digit
identifies the class number and the second identifies the
division number within that class.
 Example: Class 1, Division 1 would be expressed as
Division 1.1
8

General Principles
 Each class or division has specific criteria that are used to
determine whether an article or substance belongs to that
class or division.
 These criteria are technically detailed and classification of an
item requires specialist knowledge of the criteria.
9

General Principles
 These classes are:
 Class 1 – Explosives
 Class 2 – Gases
 Class 3 – Flammable Liquids
 Class 4 – Flammable Solids
 Class 5 – Oxidizing Substances and Organic Peroxides
 Class 6 – Toxic and Infectious Substances
 Class 7 – Radioactive Material
 Class 8 – Corrosives
 Class 9 – Miscellaneous Dangerous Substances and Articles
10

General Principles
 Some dangerous goods may have characteristics that meet
the classification criteria of more than one class or division.
 Under these circumstances the substances is said to have
both a primary and subsidiary risk.
 The classes have been arranged/numbered by the type of
hazard involved.
 The order in which the classes are shown does not imply a
relative degree of danger or the precedence of the hazard
involved.
11

Class 1 - Explosives
 Explosive articles and substances are assigned to one of six
divisions and to one of thirteen compatibility groups.
Division Hazard
1.1 Mass explosion hazard
1.2 Projectile but no mass explosion hazard
1.3
Fire hazard and either minor blast hazard or minor
projection hazard or both, but not mass explosion
1.4 Minor explosion hazard and largely confined to the
package
1.5 Very insensitive explosives
1.6
Extremely insensitive articles with no mass explosion

1.3 Fire hazard and either a minor blast
hazard or a minor projection hazard or
both, but not a mass explosion hazard

1.4 No significant blast hazard Safety Devices
1.5 Insensitive explosives with a mass

Blasting Agent
1.6 Extremely insensitive articles which
do not have a mass explosion hazard

Class 2 - Gases
 Class 2 comprises compressed gases, liquefied gases,
dissolved gases, refrigerated liquefied gases, mixtures of
gases that contain vapors of substances of other classes,
articles charged with a gas, and aerosols.
 Class 2 substances are assigned to one of three divisions:
 Division 2.1 – Flammable Gas
 Division 2.2 – Non flammable, Non-toxic Gas
 Division 2.3 – Toxic Gas
33

Class 2 - Gases
Class Category Label Example
2
Gases
2.1 Flammable gases Butane, Propane
2.2 Non flammable, non
‐ ‐
toxic gases
Argon, Oxygen
2.3 Toxic gases Insecticide,
Pesticide Gas
44

Class 3 - Flammable Liquids
 Class 3 includes flammable liquids and liquid desensitized
explosives.
 Class 3 comprises liquids, mixtures of liquids, liquids
containing solids in solution or in suspension which have a
flash point of not more than 60° C closed-cup (65.5° C open-
cup test).
 Liquids offered for transport at or above their flashpoints
are regulated
 Substances transported at elevated temperatures in a
liquid state and which give off a flammable vapor at
temperatures encountered during transport are regulated
46

 Liquids with a flash point exceeding 35° C which do not
sustain combustion are not regulated
 Class 3 packing group: determined by its flash point and
boiling point

Class 4 - Flammable Solids
 Class 4 is assigned to three divisions:
 Division 4.1 – Flammable Solids
 Readily combustible or may cause
or contribute to fire through
friction, self-reactive substances,
or desensitized explosives
 Division 4.2 – Substances liable to
spontaneous combustion
 Liable to spontaneous heating or
to heating up when in contact
with air
57

Class 4 - Flammable Solids
 Division 4.3 – Substances which, in contact with water,
emit flammable gases (Dangerous when wet)
 By interaction with water are liable to become
spontaneously flammable or give off dangerous
quantities of flammable gases
58

Class 5 – Oxidizing Substances
and Organic Peroxides

 Class 5 is divided into two divisions:
 Division 5.1 – Oxidizing substances
 Cause or contribute to the combustion of other materials by
providing oxygen
 Division 5.2 – Organic Peroxides
 Thermally unstable and have one or more of these properties:
 Be liable to explosive decomposition
 Burn rapidly
 Be sensitive to impact or friction
 React dangerously with other substances
 Cause damage to the eyes

Class 6 - Toxic and Infectious
Substances

Substances
 Class 6 is divided into two divisions:
 Division 6.1 – Toxic Substances
 Substances liable to cause death, injury, or harm to human
health if swallowed, inhaled, or contacted by skin
 A Division 6.1 substance must be assigned a packing group
according to its degree of toxic hazard in transport
 To be classified a Division 6.1 Toxic Substance a substance
must meet at minimum the criteria for Packing Group III:
 Division 6.2 – Infectious Substances
 Substances known or reasonably expected to contain
pathogens

total activity in the consignment exceed the value detailed
in Section 10 of these regulations.

Class 8 - Corrosives
 Substances which by chemical action, can cause severe
damage when in contact with living tissue, or if leaked while
in transport will damage or destroy other goods.
 Assigned to packing groups based on the length of time of
contact necessary to produce full thickness destruction of
human skin
89

Class 9 - Miscellaneous
Substances & Articles

Class 9 - Miscellaneous Substances
and Articles
 Articles and substances, which during transport, present a
danger not covered by the other 8 hazard classes.
 Class 9 includes (but not limited to):
 Environmentally hazardous substances
 Magnetized materials
 Lithium batteries
 Elevated temperature substances
 Consumer Commodities
 Materials packaged and distributed in a form intended or suitable
