(a) it is listed by name in Schedule 1 and is in any form, state or
concentration that meets the criteria in this Part for inclusion in at least
one of the 9 classes of dangerous goods; or
(b) it is not listed by name in Schedule 1 but meets the criteria in this
Part for inclusion in at least one of the 9 classes of dangerous goods.
The consignor is responsible for determining the classification of dangerous
goods. This activity is normally done by, or in consultation with, a person who
understands the nature of the dangerous goods such as a manufacturer, a person
who formulates, blends or otherwise prepares mixtures or solutions of goods or,
in the case of infectious substances, a doctor, scientist, veterinarian,
epidemiologist, genetic engineer, microbiologist, pathologist, nurse, coroner
or laboratory technologist or technician.
(1) Before allowinga carrier to take possession of dangerous
goods for transport, the consignor must determine the classification of the
dangerous goods in accordance with this Part.
(2) When importing dangerous goods into Canada, the consignor must ensure
that they have the correct classification before they are transported in
Canada.
(3) A consignor may use a classification that was determined by
(a) for Class 1, Explosives, the Chief Inspector of Explosives,
Department of Natural Resources;
(b) for Class 6.2, Infectious Substances, the Director, Office of
Biosafety, Health Canada, or the Director, Biohazard Containment and Safety,
Canadian Food Inspection Agency;
(c) a previous consignor of the dangerous goods; or
(d) the manufacturer.
(4) A consignor may use the appropriate classification in the ICAO
Technical Instructions, the IMDG Code or the UN Recommendations to transport
dangerous goods within Canada by a road vehicle, a railway vehicle or a ship on
a domestic voyage if these Regulations or the document from which the
classification is taken does not forbid their transport.
(5) If an error in classification is noticed or if there are reasonable
grounds to suspect an error in classification, the consignor must not allow a
carrier to take possession of the dangerous goods for transport until the
classification has been verified or corrected.
(6) A carrier who notices an error in classification or has reasonable
grounds to suspect an error in classification while the dangerous goods are in
transport must advise the consignor and must stop transporting the dangerous
goods until the consignor verifies or corrects the classification. The
consignor must immediately verify or correct the classification and ensure that
the carrier is provided with the verified or corrected classification.
When reading sections 2.3 to 2.6, it is useful to remember that the word
"classification" is defined in Part 1 and includes, as applicable, the shipping
name, primary class, compatibility group, subsidiary class, UN number, packing
group and risk group of dangerous goods.
If a name of dangerous goods is shown as a shipping name in column 2 of Schedule
1, that name must be used as the shipping name. That shipping name and the
corresponding data for that shipping name in columns 1, 3 and 4 of Schedule 1
must be used as the classification of the dangerous goods.
For example, the name ACETONE is shown in column 2 of Schedule 1. ACETONE is the
shipping name. The class, 3, is shown in column 3, the UN number, UN1090, is
shown in column 1 and the packing group, II, is shown in column 4. Similarly,
the name CHARGES, DEPTH, is shown in column 2 of Schedule 1. CHARGES, DEPTH, is
the shipping name. The class, 1.1D, is shown in column 3, the UN number,
UN0056, is shown in column 1 and the packing group, II, is shown in column 4.
If, in accordance with the criteria and tests in this Part, a substance is
included in only one class and one packing group, the substance is dangerous
goods and the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and that is most consistent with the class and
the packing group determined by the criteria and tests must be selected as the
shipping name. That shipping name and the corresponding data for that shipping
name in columns 1, 3 and 4 of Schedule 1 must be used as the classification of
the dangerous goods.
The word "potential" is used in paragraphs (a), (b) and (c) of this section
because the final subsidiary class or classes and the final packing group are
determined in accordance with paragraph (d).
If, in accordance with the criteria and tests in this Part, a substance meets
the criteria for inclusion in more than one class or packing group, the
substance is dangerous goods and its classification is determined in the
following manner:
(a) the classes in which the dangerous goods are included are ranked in
order of precedence in accordance with section 2.8 to determine the primary
class and the potential subsidiary class or classes;
(b) the potential packing group is the one with the lowest roman numeral;
(c) the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and for which the corresponding data in columns
1,3 and 4 are the most consistent with the primary class, the potential
subsidiary class or classes and the potential packing group are selected; and
(d) the shipping name and the corresponding data in columns 1,3
and 4 of Schedule 1 are used as the classification of the dangerous goods.
A mixture or solution of substances that are not dangerous goods and one
substance that is dangerous goods and that is listed by name in Schedule 1 has
the classification shown for the dangerous goods in that Schedule if the
mixture or solution is still dangerous goods in accordance with paragraph
2.1(a) and the mixture or solution is not identified by a shipping name in
Schedule 1. However, if the classification for the dangerous goods does not
precisely describe the mixture or solution but the mixture or solution meets
the criteria in this Part for inclusion in at least one of the 9 classes of
dangerous goods, then sections 2.4 and 2.5 must be used to determine its
classification.
(1) A substancethat is not a mixture or solution is a marine
pollutant if
(a) there is the letter "P" (marine pollutant) or there are the letters
"PP" (severe marine pollutant) incolumn 10 of Schedule 1 opposite the
shipping name of the substance;
(b) the substance is listed by name in column 1 of Appendix 1, Marine
Pollutants, to this Part; or
(c) the substance meets the criteria for a marine pollutant in accordance
with the IMDG Code.
(2) A mixture or solution is a marine pollutant if it contains
(a) 1 per cent or more of a severe marine pollutant; or
(b) 10 per cent or more of a marine pollutant as determined under
paragraph (a) or under subsection (1).
(3) When ashippingname has opposite it in column 10 of
Schedule 1the symbol ".",the consignor must determine,
in accordance with subsections (1) and (2), if the substance to be transported
underthe shipping name is a marine pollutant or a severe marine
pollutant.
A shipping name may cover several distinct substances, one of which may be a
marine pollutant while others are not. In this case, the shipping name has
opposite it the symbol ".". Depending upon the actual substance, the
requirements related to a marine pollutant may apply.
Marine pollutants and severe marine pollutants are required to be identified on a
shipping document in Part 3, Documentation, and on a means of containment in
Part 4, Dangerous Goods Safety Marks.
(1) When dangerous goods meet the criteria for inclusion in more than one
class but meet the criteria for inclusion in only one of the following classes,
that one class is the primary class. The classes are
(a) Class 1, Explosives, except for the following dangerous goods for
which Class 1 is a subsidiary class:
(i) UN3101,ORGANIC PEROXIDE TYPE B, LIQUID,
(ii) UN3102,ORGANIC PEROXIDE TYPE B, SOLID,
(iii) UN3111,ORGANIC PEROXIDE TYPE B, LIQUID, TEMPERATURE
CONTROLLED,
(iv) UN3112,ORGANIC PEROXIDE TYPE B, SOLID, TEMPERATURE
CONTROLLED,
(v) UN3221,SELF-REACTIVE LIQUID TYPE B,
(vi) UN3222,SELF-REACTIVE SOLID TYPE B,
(vii) UN3231,SELF-REACTIVE LIQUID TYPE B, TEMPERATURE CONTROLLED,
and
(viii) UN3232,SELF-REACTIVE SOLID TYPE B, TEMPERATURE CONTROLLED;
(b) Class 2, Gases, and within this class, Class 2.3, Toxic Gases, takes
precedence over Class 2.1, Flammable Gases, and Class 2.1, Flammable Gases,
takes precedence over Class 2.2, Non-flammable and Non-toxic Gases;
(c) Class 4.1, Flammable Solids, desensitized explosives included in
Packing Group I or self-reactive substances;
(d) Class 4.2, Substances Liable to Spontaneous Combustion, pyrophoric
solids or liquids included in Packing Group I;
(e) Class 5.2, Organic Peroxides;
(f) Class 6.1, Toxic Substances, that are included in Packing Group I,
due to inhalation toxicity;
(g) Class 6.2, Infectious Substances; and
(h) Class 7, Radioactive Materials.
If a substance meets the criteria for inclusion in more than one of the classes
identified in subsection (1), the person doing the classification may seek
assistance by contacting Transport Canada, Transport Dangerous Goods
Directorate, through CANUTEC at 613-992-4624.
(2) Despite paragraph (1)(f), Class 8 is the primary class when a
substance meets the criteria for inclusion in
(a) Class 8, Corrosives;
(b) Packing Group I due to inhalation toxicity of dusts or mists; and
(c) Packing Group III due to oral or dermal toxicity.
(3) A consignor must determine the order of precedence among classes that
are not listed in subsection (1) in accordance with the following table, except
that Class 6.1 takes precedence if a substance is a pesticide under the
"Pesticide Act" and is included in Class 6.1, Packing Group III, and in Class
3, Packing Group III.
Example of How to Use the Precedence of Classes Table
Suppose that, after testing,it is found that a substance meets the
criteria for inclusion in Class 3, Packing Group I, in Class 8 (L for liquid),
Packing Group II, and in Class 6.1, Packing Group II, dermal toxicity. The
potential packing group is Packing Group I because it has the lowest roman
numeral (see paragraph 2.5(b)).
To determine the primary class, compare the classes two at a time. As the first
combination, consider Class 3, Packing Group I, and Class 8, Packing Group II
(L for liquid). Go to the table and find Class 3, Packing Group I, in the
extreme left column. Follow that line across to the column on the right that
refers to Class 8, Packing Group II (L for liquid). The class that takes
precedence is the one at the point where the lines intersect in the column. In
this combination Class 3 takes precedence over Class 8. Class 8 is set aside.
Do the same thing with the combination of Class 3, Packing Group I, and Class
6.1, Packing Group II (D for dermal). In this combination Class 3 takes
precedence. Class 6.1 is set aside, leaving Class 3 as the primary class.
As there is no precedence between or among subsidiary classes, each of Class 6.1
and Class 8 is a potential subsidiary class.
Conclusion: In this example, the primary class is Class 3, each of Class 6.1 and
Class 8 is a potential subsidiary class and the potential packing group is
Packing Group I. The word "potential" is used here because the final subsidiary
class or classes and the final packing group are determined in accordance with
paragraph 2.5(d).

Precedence of Classes
Class and Packing Group
Spaces in the table denote impossible combinations.
Substances are included in Class 1, Explosives, if they are
(a) capable, by chemical reaction, of producing gas at a temperature,
pressure and speed that would damage the surroundings; or
(b) designed to produce an explosive or pyrotechnic effect by heat,
light, sound, gas or smoke or a combination of those means as a result of
non-detonative, self-sustaining exothermic chemical reactions.
Explosives are divided into 13 compatibility groups as described in Appendix 2,
Description of Compatibility Groups, Class 1, Explosives, to this Part.
Compatibility groups are used to determine which explosives may be transported
together. See section 5.7 of Part 5, Means of Containment.
(a) Class 2.1, Flammable Gases, which consists of gases that, at 20°C and
an absolute pressure of 101.3 kPa,
(i) are ignitable when in a mixture of 13 per cent or less by volume with
air, or
(ii) have a flammability range with air of at least 12 percentage points
determined in accordance with tests or calculations in ISO 10156;
(b) Class 2.2, Non-flammable and Non-toxic Gases, which consists of gases
that are transported at an absolute pressure greater than or equal to 280 kPa
at 20°C, or as refrigerated liquids, and that are not included in Class 2.1,
Flammable Gases, or Class 2.3, Toxic Gases; and
(c) Class 2.3, Toxic Gases, which consists of gases that
(i) are known to be toxic or corrosive to humans according to CGA P-20,
ISO Standard 10298 or otherdocumentary evidence published in technical
journals or government publications, or
(ii) have an LC50 value less than or equal to 5 000 mL/m3.
This section provides a method for making an acceptable approximation of the LC50
of a mixture of gases. The methods in paragraphs 2.16(a) and (b) are more
exact.
To determine the LC50of a mixture of gases when the LC50
of each of the gases is known, use5 000 mL/m3 as the toxic
limit and,
(a) if the mixture contains only one gas with an LC50 less
than or equal to the toxic limit (called "Gas A"), use the following
calculation:
.
or
(b) if the mixture contains more than one gas with an LC50 less
than or equal to the toxic limit (called "Gas A", "Gas B", etc.),
(i) determine the contributing number (CN) of each of the gases with an LC50
less than or equal to the toxic limit using the formula
(ii) combine the contributing numbers (CN) of each gas with an LC50
less than or equal to the toxic limit using the formula
and
(iii) obtain the LC50 of the mixture by dividing 1 by the
number T (LC50 of the mixture = 1 / T).
(1) Substances that are liquids or liquids containing solids in solution
or suspension are included in Class 3, Flammable Liquids, if they
(a) have a flash point less than or equal to 60.5°C using the closed-cup
test method referred to in Chapter 2.3 of the UN Recommendations; or
A flash point of 65.6°C, using the open-cup test method
referred to in Chapter 2.3 of the UN Recommendations, is equivalent to 60.5°C using the closed-cup test.
(b) are intended or expected to be at a temperature that is greater than
or equal to their flash point at any time while the substances are in
transport.
The UN number and shipping name for the dangerous goods referred to in paragraph
(b) are UN3256, ELEVATED TEMPERATURE LIQUID, FLAMMABLE, N.O.S.
(2) Despite paragraph (1)(a), liquids that have a flash point greater
than 35°C are not included in Class 3, Flammable Liquids,if they
(a) do not sustain combustion, as determined in accordance with the
sustained combustibility test referred to in section 2.3.1.3 of Chapter 2.3 of
the UN Recommendations;
(b) have a fire point greater than 100°C, as determined in accordance
with ISO 2592; or
(c) are water-miscible solutions with a water content greater than 90 per
cent by mass.
(1) Flammable liquids included in Class 3, Flammable Liquids, are
included in one of the following packing groups:
(a) Packing Group I, if they have an initial boiling point of 35°C or
less at an absolute pressure of 101.3 kPa and any flash point;
(b) Packing Group II, if they have an initial boiling point greater than
35°C at an absolute pressure of 101.3 kPa and a flash point less than 23°C; or
(c) Packing Group III, if the criteria for inclusion in Packing Group I
or II are not met.
(2) Despite subsection (1), for dangerous goods included in Class 3,
Flammable Liquids,
(a) when the packing group is unknown, the consignor may include the
dangerous goods in Packing Group I; or
(b) when the packing group is reasonably believed or is known to be
Packing Group II or III, the consignor may include the dangerous goods in
Packing Group II but, if the substance has the same characteristics as UN1203,
GASOLINE, it may also be transported as Packing Group II.
(3) Despite paragraph (1)(b), a viscous substance that has an initial
boiling point greater than 35°C at an absolute pressure of 101.3 kPa and a
flash point less than 23°C may be included in Packing Group III if
(a) the substance or any separated solvent does not meet the criteria for
inclusion in Class 6.1 or Class 8;
(b) the substance meets the Packing Group III criteria of the solvent
separation test in section 32.5.1 of Part III of the Manual of Tests and
Criteria; and
(c) the substance
(i) has been tested in accordance with either ASTM D 1200 or ISO 2431,
and
(ii) has a kinematic viscosity, measured as flow time, that is within the

This section provides a method for making an acceptable approximation of the LD50
of a mixture of solid or liquid substances. The methods in paragraphs 2.30(a)
and (b) are more exact.
To determine the LD50of a mixture of solid or liquid
substances when the LD50 of each of the substances is known, use 1
000 mg/kg as the toxic limit and
(a) if the mixture contains only one substance with an LD50 less
than or equal to the toxic limit (called "Substance A"), use the following
calculation:
or
(b) if the mixture contains more than one substance with an LD50
less than or equal to the toxic limit (called "Substance A", "Substance B",
etc.),
(i) determine the lowest LD50 of all substances, assign that
LD50 to all substances whose actual LD50 is less than or
equal to the toxic limit, then use the calculation in paragraph (a) using that
assigned LD50 and taking as the mass of Substance A in the formula
the total of the masses of all substances whose actual LD50 is less
than or equal to the toxic limit, or
(ii) use the following calculations
(A) determine the contributing number (CN) of each of the substances with an LD50 less than or equal to the toxic limit using the formula
(B) combine the contributing numbers (CN) of each substance with an LD50
less than or equal to the toxic limit as
and
(C) obtain the LD50 of the mixture by dividing 1 by the number
T (LD50 of the mixture = 1 / T).
LC50 values for a substance in the form of a dust, mist or vapour or
for a mixture of substances in the form of a dust, mist or vapour must be
determined
(a) by using the LC50 values published in technical journals
or in government publications;
(b) in accordance with sections 2.6.2.2.4.2 to 2.6.2.2.4.7 of Chapter 2.6
of the UN Recommendations; or
(c) for a mixture of substances, in accordance with section 2.33.
This section provides a method for making an acceptable approximation of the LC50
of a mixture of substances. The methods in paragraphs 2.32(a) and (b) are more
exact. SOR/2002-306
To determine the LC50 of a mixture of substances that are in the form
of a dust, mist or vapour, when the LC50 of each of the substances
is known, make the determination in accordance with section 2.17, except that
for a dust use 10 mg/L as the toxic limit and for a mist use 2 mg/L as the
toxic limit. For a substance in the form of vapour the toxic limit is the same
as for a gas, which is 5 000 mL/m3.
(1) The first step in determining the packing group of a mixture of
liquids with an inhalation toxicity by vapour when one or more of the
substances has an LC50 (vapour) less than or equal to 5 000 mL/m3,
and the LC50 of each substance is known, is to determine the
following data:
(a) determine the LC50 (vapour) for the mixture in accordance
with section 2.33;
(b) where Pi is the vapour pressure of the ith substance
in kPa at 20°C and an absolute pressure of 101.3 kPa, determinethe
volatility, Vi, of each substance in the mixture as
Vi = Pi multiplied by 106 then divided by
101.3;
(c) determine the ratio of the volatility of a substance to its LC50
for each substance with an LC50 less than or equal to 5 000 mL/m3
as
Ri = Vi divided by the LC50 of the ith
substance;
and
(d) set R equal to the sum of the Ri for each of the
substances with an LC50 less than or equal to 5 000 mL/m3
as
R = R1 + R2 + . + (as needed).
(2) Using the data determined in accordance with subsection (1), the
mixture is included in one of the following packing groups:
(a) Packing Group I, if
(i) R is greater than or equal to 10, and
(ii) the LC50 (mixture) is less than or equal to 1 000 mL/m3;
(b) Packing Group II, if
(i) R is greater than or equal to 1,
(ii) the LC50 (mixture) is less than or equal to 3 000 mL/m3,
and
(iii) the criteria for inclusion inPacking Group I are not met;
or
(c) Packing Group III, if
(i) R is greater than or equal to 0.2,
(ii) the LC50 (mixture) is less than or equal to 5 000 mL/m3,
and
(iii) the criteria for inclusion in Packing Group I or II are not met.
This section provides a method of directly determining the packing group of a
mixture of liquids that has an inhalation toxicity without requiring that the
exact LC50 be found.
(1) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group I if it meets the following criteria:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 1 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is diluted with 9 equal volumes of air to form a test atmosphere and 10 young
adult albino rats (5 male and 5 female) are exposed to the test atmosphere for
1 hour and observed for 14 days, the result is the death of 5 or more of the
animals within the 14-day observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 1 000 mL/m3 and a volatility greater than or equal to 10
times the mixture's LC50.
(2) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group II if it meets the following criteria and the
criteria for inclusion in Packing Group I are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 3 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is used to form a test atmosphere and 10 young adult albino rats (5 male and 5
female) are exposed to the test atmosphere for 1 hour and observed for 14 days,
the result is the death of 5 or more of the animals within the 14-day
observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 3 000 mL/m3 and a volatility greater than or equal to the
mixture's LC50.
(3) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group III if it meets the following criteria and the
criteria for inclusion in Packing Group I or II are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 5 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when the vapour pressure of the mixture is measured, the vapour
concentration is greater than or equal to 1 000 mL/m3.
In this case the mixture is presumed to have an LC50 less than or
equal to 5 000 mL/m3 and a volatility greater than or equal to 0.2
times the mixture's LC50.
(4) If only LC50 data relating to 4-hour exposures to dust or
mist are available, those figures can be multiplied by 4 and the result taken
as the LC50 data for 1 hour, that is LC50 4 hours (dust
or mist) multiplied by 4 is equivalent to LC50 1 hour.
(5) If only LC50 data relating to 4-hour exposures to vapour
are available, those figures can be multiplied by 2 and the result taken as the
LC50 data for 1 hour, that is LC50 4 hours (vapour)
multiplied by 2 is equivalent to LC50 1 hour.
Infectious substances are divided into Risk Groups. Risk Group I includes
micro-organisms that are unlikely to cause human or animal disease. Risk Group
I is not regulated by these Regulations.
Assistance for classifying infectious substances may be obtained from the
Director, Office of Biosafety, Health Canada, or from the Director, Biohazard
Containment and Safety, Canadian Food Inspection Agency.
Micro-organisms that affect humans or animals are included in Class 6.2,
Infectious Substances, and the following risk groups:
(a) Risk Group 4, if they are included in the list of Risk Group 4
substances in Appendix 3, Guide to Risk Group Assignments, to this Part or if
they exhibit characteristics similar to those substances, including the
following:
(i) the disease they cause has serious effects that may be irreversible
or lethal in humans who or animals that have contracted the disease,
(ii) the micro-organisms are readily transmitted directly or indirectly
or by casual contact, and
(iii) effective treatment and preventive measures are not generally
available;
(b) Risk Group 3, if they are included in the list of Risk Group 3
substances in Appendix 3, Guide to Risk Group Assignments, to this Part or if
they exhibit characteristics similar to those substances, including the
following:
(i) the disease they cause seriously affects the health of humans who or
animals that have contracted the disease,
(ii) the micro-organisms are not readily transmitted by casual contact,
and
(iii) the disease they cause can be treated by antimicrobial or
antiparasitic agents; and
(c) Risk Group 2, if they are included in the list of Risk Group 2
substances in Appendix 3, Guide to Risk Group Assignments, to this Part or if
they exhibit characteristics similar to those substances, including the
following:
(i) the disease they cause does not seriously affect the health of humans
who or animals that have contracted the disease,
(ii) the micro-organisms are rarely transmitted by direct contact, and
(iii) there exists readily available treatment for humans who or animals
that have contracted the disease they cause.
Substances with a specific activity greater than 70 kBq/kg are included in Class
7, Radioactive Materials.
In these Regulations the words "Class 7, Radioactive Materials" are used rather
than the words that are used in the schedule to the Act, "Class 7, Nuclear
Substances, within the meaning of the Nuclear Safety and Control Act, that are
radioactive" so that the Regulations are more easily read in conjunction with
international documents incorporated by reference in them.
Substances are included in Class 8, Corrosives, if they
(a) are known to cause full thickness destruction of human skin, that is,
skin lesions that are permanent and destroy all layers of the outer skin
through to the internal tissues;
(b) cause full thickness skin destruction, as determined in accordance
with the OECD Guidelines; or
(c) do not cause full thickness destruction of skin, but exhibit a
corrosion rate that exceeds 6.25 mm per year at a test temperature of 55°C, as
determined in accordance with the ASTM Corrosion Test.
(1) If a substance is known to be included in Class 8, Corrosives, and
that knowledge is based on documentary evidence published in technical journals
or government publications and testing is not done to determine the packing
group, the substance must be included in Packing Group I.
(2) Class 8, Corrosives, are included in one of the following packing
groups:
(a) Packing Group I, if
(i) they are known to cause full thickness destruction of human skin,
that is, skin lesions that are permanent and that destroy all layers of the
outer skin through to the internal tissues, or
(ii) full thickness destruction of intact skin tissue occurs within an
observation period of 60 minutes after an exposure time of 3 minutes or less,
as determined in accordance with the OECD Guidelines;
(b) Packing Group II, if full thickness destruction of skin occurs within
an observation period of 14 days after an exposure time of more than 3 minutes
but not more than 60 minutes, as determined in accordance with the OECD
Guidelines; or
(c) Packing Group III, if
(i) full thickness destruction of intact skin tissue occurs within an
observation period of 14 days after an exposure time of more than 60 minutes
but not more than 4 hours, as determined in accordance with the OECD
Guidelines, or
(ii) they exhibit a corrosion rate that exceeds 6.25 mm per year at a
test temperature of 55°C on steel surfaces, type P235 referred to in ISO 9328-2
or a similar type or on aluminum surfaces, non-clad types 7075-T6 or AZ5GU-T6,
as determined in accordance with the ASTM Corrosion Test.
(3) An in vitro test may be used instead of the test in the OECD
Guidelines.

2.1 Determining When Substances Are Dangerous Goods
A substance is dangerous goods when
(a) it is listed by name in Schedule 1 and is in any form, state or
concentration that meets the criteria in this Part for inclusion in at least
one of the 9 classes of dangerous goods; or
(b) it is not listed by name in Schedule 1 but meets the criteria in this
Part for inclusion in at least one of the 9 classes of dangerous goods.
2.2 Responsibility for Classification
The consignor is responsible for determining the classification of dangerous
goods. This activity is normally done by, or in consultation with, a person who
understands the nature of the dangerous goods such as a manufacturer, a person
who formulates, blends or otherwise prepares mixtures or solutions of goods or,
in the case of infectious substances, a doctor, scientist, veterinarian,
epidemiologist, genetic engineer, microbiologist, pathologist, nurse, coroner
or laboratory technologist or technician.
(1) Before allowinga carrier to take possession of dangerous
goods for transport, the consignor must determine the classification of the
dangerous goods in accordance with this Part.
(2) When importing dangerous goods into Canada, the consignor must ensure
that they have the correct classification before they are transported in
Canada.
(3) A consignor may use a classification that was determined by
(a) for Class 1, Explosives, the Chief Inspector of Explosives,
Department of Natural Resources;
(b) for Class 6.2, Infectious Substances, the Director, Office of
Biosafety, Health Canada, or the Director, Biohazard Containment and Safety,
Canadian Food Inspection Agency;
(c) a previous consignor of the dangerous goods; or
(d) the manufacturer.
(4) A consignor may use the appropriate classification in the ICAO
Technical Instructions, the IMDG Code or the UN Recommendations to transport
dangerous goods within Canada by a road vehicle, a railway vehicle or a ship on
a domestic voyage if these Regulations or the document from which the
classification is taken does not forbid their transport.
(5) If an error in classification is noticed or if there are reasonable
grounds to suspect an error in classification, the consignor must not allow a
carrier to take possession of the dangerous goods for transport until the
classification has been verified or corrected.
(6) A carrier who notices an error in classification or has reasonable
grounds to suspect an error in classification while the dangerous goods are in
transport must advise the consignor and must stop transporting the dangerous
goods until the consignor verifies or corrects the classification. The
consignor must immediately verify or correct the classification and ensure that
the carrier is provided with the verified or corrected classification.
When reading sections 2.3 to 2.6, it is useful to remember that the word
"classification" is defined in Part 1 and includes, as applicable, the shipping
name, primary class, compatibility group, subsidiary class, UN number, packing
group and risk group of dangerous goods.
2.3 Classifying Substances That Are Listed by Name in Schedule 1
If a name of dangerous goods is shown as a shipping name in column 2 of Schedule
1, that name must be used as the shipping name. That shipping name and the
corresponding data for that shipping name in columns 1, 3 and 4 of Schedule 1
must be used as the classification of the dangerous goods.
For example, the name ACETONE is shown in column 2 of Schedule 1. ACETONE is the
shipping name. The class, 3, is shown in column 3, the UN number, UN1090, is
shown in column 1 and the packing group, II, is shown in column 4. Similarly,
the name CHARGES, DEPTH, is shown in column 2 of Schedule 1. CHARGES, DEPTH, is
the shipping name. The class, 1.1D, is shown in column 3, the UN number,
UN0056, is shown in column 1 and the packing group, II, is shown in column 4.
2.4 Classifying Substances That Are Included in Only One Class and One Packing
Group
If, in accordance with the criteria and tests in this Part, a substance is
included in only one class and one packing group, the substance is dangerous
goods and the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and that is most consistent with the class and
the packing group determined by the criteria and tests must be selected as the
shipping name. That shipping name and the corresponding data for that shipping
name in columns 1, 3 and 4 of Schedule 1 must be used as the classification of
the dangerous goods.
2.5 Classifying Substances That Are Included in More Than One Class or Packing
Group
The word "potential" is used in paragraphs (a), (b) and (c) of this section
because the final subsidiary class or classes and the final packing group are
determined in accordance with paragraph (d).
If, in accordance with the criteria and tests in this Part, a substance meets
the criteria for inclusion in more than one class or packing group, the
substance is dangerous goods and its classification is determined in the
following manner:
(a) the classes in which the dangerous goods are included are ranked in
order of precedence in accordance with section 2.8 to determine the primary
class and the potential subsidiary class or classes;
(b) the potential packing group is the one with the lowest roman numeral;
(c) the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and for which the corresponding data in columns
1,3 and 4 are the most consistent with the primary class, the potential
subsidiary class or classes and the potential packing group are selected; and
(d) the shipping name and the corresponding data in columns 1,3
and 4 of Schedule 1 are used as the classification of the dangerous goods.
2.6 Classifying a Mixture or Solution
A mixture or solution of substances that are not dangerous goods and one
substance that is dangerous goods and that is listed by name in Schedule 1 has
the classification shown for the dangerous goods in that Schedule if the
mixture or solution is still dangerous goods in accordance with paragraph
2.1(a) and the mixture or solution is not identified by a shipping name in
Schedule 1. However, if the classification for the dangerous goods does not
precisely describe the mixture or solution but the mixture or solution meets
the criteria in this Part for inclusion in at least one of the 9 classes of
dangerous goods, then sections 2.4 and 2.5 must be used to determine its
classification.
2.7 Marine Pollutants
(1) A substancethat is not a mixture or solution is a marine
pollutant if
(a) there is the letter "P" (marine pollutant) or there are the letters
"PP" (severe marine pollutant) incolumn 10 of Schedule 1 opposite the
shipping name of the substance;
(b) the substance is listed by name in column 1 of Appendix 1, Marine
Pollutants, to this Part; or
(c) the substance meets the criteria for a marine pollutant in accordance
with the IMDG Code.
(2) A mixture or solution is a marine pollutant if it contains
(a) 1 per cent or more of a severe marine pollutant; or
(b) 10 per cent or more of a marine pollutant as determined under
paragraph (a) or under subsection (1).
(3) When ashippingname has opposite it in column 10 of
Schedule 1the symbol ".",the consignor must determine,
in accordance with subsections (1) and (2), if the substance to be transported
underthe shipping name is a marine pollutant or a severe marine
pollutant.
A shipping name may cover several distinct substances, one of which may be a
marine pollutant while others are not. In this case, the shipping name has
opposite it the symbol ".". Depending upon the actual substance, the
requirements related to a marine pollutant may apply.
Marine pollutants and severe marine pollutants are required to be identified on a
shipping document in Part 3, Documentation, and on a means of containment in
Part 4, Dangerous Goods Safety Marks.
2.8 Precedence of Classes
(1) When dangerous goods meet the criteria for inclusion in more than one
class but meet the criteria for inclusion in only one of the following classes,
that one class is the primary class. The classes are
(a) Class 1, Explosives, except for the following dangerous goods for
which Class 1 is a subsidiary class:
(i) UN3101,ORGANIC PEROXIDE TYPE B, LIQUID,
(ii) UN3102,ORGANIC PEROXIDE TYPE B, SOLID,
(iii) UN3111,ORGANIC PEROXIDE TYPE B, LIQUID, TEMPERATURE
CONTROLLED,
(iv) UN3112,ORGANIC PEROXIDE TYPE B, SOLID, TEMPERATURE
CONTROLLED,
(v) UN3221,SELF-REACTIVE LIQUID TYPE B,
(vi) UN3222,SELF-REACTIVE SOLID TYPE B,
(vii) UN3231,SELF-REACTIVE LIQUID TYPE B, TEMPERATURE CONTROLLED,
and
(viii) UN3232,SELF-REACTIVE SOLID TYPE B, TEMPERATURE CONTROLLED;
(b) Class 2, Gases, and within this class, Class 2.3, Toxic Gases, takes
precedence over Class 2.1, Flammable Gases, and Class 2.1, Flammable Gases,
takes precedence over Class 2.2, Non-flammable and Non-toxic Gases;
(c) Class 4.1, Flammable Solids, desensitized explosives included in
Packing Group I or self-reactive substances;
(d) Class 4.2, Substances Liable to Spontaneous Combustion, pyrophoric
solids or liquids included in Packing Group I;
(e) Class 5.2, Organic Peroxides;
(f) Class 6.1, Toxic Substances, that are included in Packing Group I,
due to inhalation toxicity;
(g) Class 6.2, Infectious Substances; and
(h) Class 7, Radioactive Materials.
If a substance meets the criteria for inclusion in more than one of the classes
identified in subsection (1), the person doing the classification may seek
assistance by contacting Transport Canada, Transport Dangerous Goods
Directorate, through CANUTEC at 613-992-4624.
(2) Despite paragraph (1)(f), Class 8 is the primary class when a
substance meets the criteria for inclusion in
(a) Class 8, Corrosives;
(b) Packing Group I due to inhalation toxicity of dusts or mists; and
(c) Packing Group III due to oral or dermal toxicity.
(3) A consignor must determine the order of precedence among classes that
are not listed in subsection (1) in accordance with the following table, except
that Class 6.1 takes precedence if a substance is a pesticide under the
"Pesticide Act" and is included in Class 6.1, Packing Group III, and in Class
3, Packing Group III.
Example of How to Use the Precedence of Classes Table
Suppose that, after testing,it is found that a substance meets the
criteria for inclusion in Class 3, Packing Group I, in Class 8 (L for liquid),
Packing Group II, and in Class 6.1, Packing Group II, dermal toxicity. The
potential packing group is Packing Group I because it has the lowest roman
numeral (see paragraph 2.5(b)).
To determine the primary class, compare the classes two at a time. As the first
combination, consider Class 3, Packing Group I, and Class 8, Packing Group II
(L for liquid). Go to the table and find Class 3, Packing Group I, in the
extreme left column. Follow that line across to the column on the right that
refers to Class 8, Packing Group II (L for liquid). The class that takes
precedence is the one at the point where the lines intersect in the column. In
this combination Class 3 takes precedence over Class 8. Class 8 is set aside.

Do the same thing with the combination of Class 3, Packing Group I, and Class
6.1, Packing Group II (D for dermal). In this combination Class 3 takes
precedence. Class 6.1 is set aside, leaving Class 3 as the primary class.

As there is no precedence between or among subsidiary classes, each of Class 6.1
and Class 8 is a potential subsidiary class.
Conclusion: In this example, the primary class is Class 3, each of Class 6.1 and
Class 8 is a potential subsidiary class and the potential packing group is
Packing Group I. The word "potential" is used here because the final subsidiary
class or classes and the final packing group are determined in accordance with
paragraph 2.5(d).

with section 2.33;
(b) where Pi is the vapour pressure of the ith substance
in kPa at 20°C and an absolute pressure of 101.3 kPa, determinethe
volatility, Vi, of each substance in the mixture as
Vi = Pi multiplied by 106 then divided by
101.3;
(c) determine the ratio of the volatility of a substance to its LC50
for each substance with an LC50 less than or equal to 5 000 mL/m3
as
Ri = Vi divided by the LC50 of the ith
substance;
and
(d) set R equal to the sum of the Ri for each of the
substances with an LC50 less than or equal to 5 000 mL/m3
as
R = R1 + R2 + . + (as needed).
(2) Using the data determined in accordance with subsection (1), the
mixture is included in one of the following packing groups:
(a) Packing Group I, if
(i) R is greater than or equal to 10, and
(ii) the LC50 (mixture) is less than or equal to 1 000 mL/m3;
(b) Packing Group II, if
(i) R is greater than or equal to 1,
(ii) the LC50 (mixture) is less than or equal to 3 000 mL/m3,
and
(iii) the criteria for inclusion inPacking Group I are not met;
or
(c) Packing Group III, if
(i) R is greater than or equal to 0.2,
(ii) the LC50 (mixture) is less than or equal to 5 000 mL/m3,
and
(iii) the criteria for inclusion in Packing Group I or II are not met.
2.35 Determination of the Packing Group of a Mixture of Liquids with an
Inhalation Toxicity and an Unknown LC50
This section provides a method of directly determining the packing group of a
mixture of liquids that has an inhalation toxicity without requiring that the
exact LC50 be found.
(1) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group I if it meets the following criteria:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 1 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is diluted with 9 equal volumes of air to form a test atmosphere and 10 young
adult albino rats (5 male and 5 female) are exposed to the test atmosphere for
1 hour and observed for 14 days, the result is the death of 5 or more of the
animals within the 14-day observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 1 000 mL/m3 and a volatility greater than or equal to 10
times the mixture's LC50.
(2) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group II if it meets the following criteria and the
criteria for inclusion in Packing Group I are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 3 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is used to form a test atmosphere and 10 young adult albino rats (5 male and 5
female) are exposed to the test atmosphere for 1 hour and observed for 14 days,
the result is the death of 5 or more of the animals within the 14-day
observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 3 000 mL/m3 and a volatility greater than or equal to the
mixture's LC50.
(3) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group III if it meets the following criteria and the
criteria for inclusion in Packing Group I or II are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 5 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when the vapour pressure of the mixture is measured, the vapour
concentration is greater than or equal to 1 000 mL/m3.
In this case the mixture is presumed to have an LC50 less than or
equal to 5 000 mL/m3 and a volatility greater than or equal to 0.2
times the mixture's LC50.
(4) If only LC50 data relating to 4-hour exposures to dust or
mist are available, those figures can be multiplied by 4 and the result taken
as the LC50 data for 1 hour, that is LC50 4 hours (dust
or mist) multiplied by 4 is equivalent to LC50 1 hour.
(5) If only LC50 data relating to 4-hour exposures to vapour
are available, those figures can be multiplied by 2 and the result taken as the
LC50 data for 1 hour, that is LC50 4 hours (vapour)
multiplied by 2 is equivalent to LC50 1 hour.
2.36 Risk Groups
Infectious substances are divided into Risk Groups. Risk Group I includes
micro-organisms that are unlikely to cause human or animal disease. Risk Group
I is not regulated by these Regulations.
Assistance for classifying infectious substances may be obtained from the
Director, Office of Biosafety, Health Canada, or from the Director, Biohazard
Containment and Safety, Canadian Food Inspection Agency.
Micro-organisms that affect humans or animals are included in Class 6.2,
Infectious Substances, and the following risk groups:
(a) Risk Group 4, if they are included in the list of Risk Group 4
substances in Appendix 3, Guide to Risk Group Assignments, to this Part or if
they exhibit characteristics similar to those substances, including the
following:
(i) the disease they cause has serious effects that may be irreversible
or lethal in humans who or animals that have contracted the disease,
(ii) the micro-organisms are readily transmitted directly or indirectly
or by casual contact, and
(iii) effective treatment and preventive measures are not generally

2.1 Determining When Substances Are Dangerous Goods
A substance is dangerous goods when
(a) it is listed by name in Schedule 1 and is in any form, state or
concentration that meets the criteria in this Part for inclusion in at least
one of the 9 classes of dangerous goods; or
(b) it is not listed by name in Schedule 1 but meets the criteria in this
Part for inclusion in at least one of the 9 classes of dangerous goods.
2.2 Responsibility for Classification
The consignor is responsible for determining the classification of dangerous
goods. This activity is normally done by, or in consultation with, a person who
understands the nature of the dangerous goods such as a manufacturer, a person
who formulates, blends or otherwise prepares mixtures or solutions of goods or,
in the case of infectious substances, a doctor, scientist, veterinarian,
epidemiologist, genetic engineer, microbiologist, pathologist, nurse, coroner
or laboratory technologist or technician.
(1) Before allowinga carrier to take possession of dangerous
goods for transport, the consignor must determine the classification of the
dangerous goods in accordance with this Part.
(2) When importing dangerous goods into Canada, the consignor must ensure
that they have the correct classification before they are transported in
Canada.
(3) A consignor may use a classification that was determined by
(a) for Class 1, Explosives, the Chief Inspector of Explosives,
Department of Natural Resources;
(b) for Class 6.2, Infectious Substances, the Director, Office of
Biosafety, Health Canada, or the Director, Biohazard Containment and Safety,
Canadian Food Inspection Agency;
(c) a previous consignor of the dangerous goods; or
(d) the manufacturer.
(4) A consignor may use the appropriate classification in the ICAO
Technical Instructions, the IMDG Code or the UN Recommendations to transport
dangerous goods within Canada by a road vehicle, a railway vehicle or a ship on
a domestic voyage if these Regulations or the document from which the
classification is taken does not forbid their transport.
(5) If an error in classification is noticed or if there are reasonable
grounds to suspect an error in classification, the consignor must not allow a
carrier to take possession of the dangerous goods for transport until the
classification has been verified or corrected.
(6) A carrier who notices an error in classification or has reasonable
grounds to suspect an error in classification while the dangerous goods are in
transport must advise the consignor and must stop transporting the dangerous
goods until the consignor verifies or corrects the classification. The
consignor must immediately verify or correct the classification and ensure that
the carrier is provided with the verified or corrected classification.
When reading sections 2.3 to 2.6, it is useful to remember that the word
"classification" is defined in Part 1 and includes, as applicable, the shipping
name, primary class, compatibility group, subsidiary class, UN number, packing
group and risk group of dangerous goods.
2.3 Classifying Substances That Are Listed by Name in Schedule 1
If a name of dangerous goods is shown as a shipping name in column 2 of Schedule
1, that name must be used as the shipping name. That shipping name and the
corresponding data for that shipping name in columns 1, 3 and 4 of Schedule 1
must be used as the classification of the dangerous goods.
For example, the name ACETONE is shown in column 2 of Schedule 1. ACETONE is the
shipping name. The class, 3, is shown in column 3, the UN number, UN1090, is
shown in column 1 and the packing group, II, is shown in column 4. Similarly,
the name CHARGES, DEPTH, is shown in column 2 of Schedule 1. CHARGES, DEPTH, is
the shipping name. The class, 1.1D, is shown in column 3, the UN number,
UN0056, is shown in column 1 and the packing group, II, is shown in column 4.
2.4 Classifying Substances That Are Included in Only One Class and One Packing
Group
If, in accordance with the criteria and tests in this Part, a substance is
included in only one class and one packing group, the substance is dangerous
goods and the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and that is most consistent with the class and
the packing group determined by the criteria and tests must be selected as the
shipping name. That shipping name and the corresponding data for that shipping
name in columns 1, 3 and 4 of Schedule 1 must be used as the classification of
the dangerous goods.
2.5 Classifying Substances That Are Included in More Than One Class or Packing
Group
The word "potential" is used in paragraphs (a), (b) and (c) of this section
because the final subsidiary class or classes and the final packing group are
determined in accordance with paragraph (d).
If, in accordance with the criteria and tests in this Part, a substance meets
the criteria for inclusion in more than one class or packing group, the
substance is dangerous goods and its classification is determined in the
following manner:
(a) the classes in which the dangerous goods are included are ranked in
order of precedence in accordance with section 2.8 to determine the primary
class and the potential subsidiary class or classes;
(b) the potential packing group is the one with the lowest roman numeral;
(c) the shipping name in column 2 of Schedule 1 that most precisely
describes the dangerous goods and for which the corresponding data in columns
1,3 and 4 are the most consistent with the primary class, the potential
subsidiary class or classes and the potential packing group are selected; and
(d) the shipping name and the corresponding data in columns 1,3
and 4 of Schedule 1 are used as the classification of the dangerous goods.
2.6 Classifying a Mixture or Solution
A mixture or solution of substances that are not dangerous goods and one
substance that is dangerous goods and that is listed by name in Schedule 1 has
the classification shown for the dangerous goods in that Schedule if the
mixture or solution is still dangerous goods in accordance with paragraph
2.1(a) and the mixture or solution is not identified by a shipping name in
Schedule 1. However, if the classification for the dangerous goods does not
precisely describe the mixture or solution but the mixture or solution meets
the criteria in this Part for inclusion in at least one of the 9 classes of
dangerous goods, then sections 2.4 and 2.5 must be used to determine its
classification.
2.7 Marine Pollutants
(1) A substancethat is not a mixture or solution is a marine
pollutant if
(a) there is the letter "P" (marine pollutant) or there are the letters
"PP" (severe marine pollutant) incolumn 10 of Schedule 1 opposite the
shipping name of the substance;
(b) the substance is listed by name in column 1 of Appendix 1, Marine
Pollutants, to this Part; or
(c) the substance meets the criteria for a marine pollutant in accordance
with the IMDG Code.
(2) A mixture or solution is a marine pollutant if it contains
(a) 1 per cent or more of a severe marine pollutant; or
(b) 10 per cent or more of a marine pollutant as determined under
paragraph (a) or under subsection (1).
(3) When ashippingname has opposite it in column 10 of
Schedule 1the symbol ".",the consignor must determine,
in accordance with subsections (1) and (2), if the substance to be transported
underthe shipping name is a marine pollutant or a severe marine
pollutant.
A shipping name may cover several distinct substances, one of which may be a
marine pollutant while others are not. In this case, the shipping name has
opposite it the symbol ".". Depending upon the actual substance, the
requirements related to a marine pollutant may apply.
Marine pollutants and severe marine pollutants are required to be identified on a
shipping document in Part 3, Documentation, and on a means of containment in
Part 4, Dangerous Goods Safety Marks.
2.8 Precedence of Classes
(1) When dangerous goods meet the criteria for inclusion in more than one
class but meet the criteria for inclusion in only one of the following classes,
that one class is the primary class. The classes are
(a) Class 1, Explosives, except for the following dangerous goods for
which Class 1 is a subsidiary class:
(i) UN3101,ORGANIC PEROXIDE TYPE B, LIQUID,
(ii) UN3102,ORGANIC PEROXIDE TYPE B, SOLID,
(iii) UN3111,ORGANIC PEROXIDE TYPE B, LIQUID, TEMPERATURE
CONTROLLED,
(iv) UN3112,ORGANIC PEROXIDE TYPE B, SOLID, TEMPERATURE
CONTROLLED,
(v) UN3221,SELF-REACTIVE LIQUID TYPE B,
(vi) UN3222,SELF-REACTIVE SOLID TYPE B,
(vii) UN3231,SELF-REACTIVE LIQUID TYPE B, TEMPERATURE CONTROLLED,
and
(viii) UN3232,SELF-REACTIVE SOLID TYPE B, TEMPERATURE CONTROLLED;
(b) Class 2, Gases, and within this class, Class 2.3, Toxic Gases, takes
precedence over Class 2.1, Flammable Gases, and Class 2.1, Flammable Gases,
takes precedence over Class 2.2, Non-flammable and Non-toxic Gases;
(c) Class 4.1, Flammable Solids, desensitized explosives included in
Packing Group I or self-reactive substances;
(d) Class 4.2, Substances Liable to Spontaneous Combustion, pyrophoric
solids or liquids included in Packing Group I;
(e) Class 5.2, Organic Peroxides;
(f) Class 6.1, Toxic Substances, that are included in Packing Group I,
due to inhalation toxicity;
(g) Class 6.2, Infectious Substances; and
(h) Class 7, Radioactive Materials.
If a substance meets the criteria for inclusion in more than one of the classes
identified in subsection (1), the person doing the classification may seek
assistance by contacting Transport Canada, Transport Dangerous Goods
Directorate, through CANUTEC at 613-992-4624.
(2) Despite paragraph (1)(f), Class 8 is the primary class when a
substance meets the criteria for inclusion in
(a) Class 8, Corrosives;
(b) Packing Group I due to inhalation toxicity of dusts or mists; and
(c) Packing Group III due to oral or dermal toxicity.
(3) A consignor must determine the order of precedence among classes that
are not listed in subsection (1) in accordance with the following table, except
that Class 6.1 takes precedence if a substance is a pesticide under the
"Pesticide Act" and is included in Class 6.1, Packing Group III, and in Class
3, Packing Group III.
Example of How to Use the Precedence of Classes Table
Suppose that, after testing,it is found that a substance meets the
criteria for inclusion in Class 3, Packing Group I, in Class 8 (L for liquid),
Packing Group II, and in Class 6.1, Packing Group II, dermal toxicity. The
potential packing group is Packing Group I because it has the lowest roman
numeral (see paragraph 2.5(b)).
To determine the primary class, compare the classes two at a time. As the first
combination, consider Class 3, Packing Group I, and Class 8, Packing Group II
(L for liquid). Go to the table and find Class 3, Packing Group I, in the
extreme left column. Follow that line across to the column on the right that
refers to Class 8, Packing Group II (L for liquid). The class that takes
precedence is the one at the point where the lines intersect in the column. In
this combination Class 3 takes precedence over Class 8. Class 8 is set aside.

As there is no precedence between or among subsidiary classes, each of Class 6.1
and Class 8 is a potential subsidiary class.
Conclusion: In this example, the primary class is Class 3, each of Class 6.1 and
Class 8 is a potential subsidiary class and the potential packing group is
Packing Group I. The word "potential" is used here because the final subsidiary
class or classes and the final packing group are determined in accordance with
paragraph 2.5(d).

2.31 Determination of LD50 (oral or dermal) of a Mixture of Substances
This section provides a method for making an acceptable approximation of the LD50
of a mixture of solid or liquid substances. The methods in paragraphs 2.30(a)
and (b) are more exact.
To determine the LD50of a mixture of solid or liquid
substances when the LD50 of each of the substances is known, use 1
000 mg/kg as the toxic limit and
(a) if the mixture contains only one substance with an LD50 less
than or equal to the toxic limit (called "Substance A"), use the following
calculation:
.
or
(b) if the mixture contains more than one substance with an LD50
less than or equal to the toxic limit (called "Substance A", "Substance B",
etc.),
(i) determine the lowest LD50 of all substances, assign that
LD50 to all substances whose actual LD50 is less than or
equal to the toxic limit, then use the calculation in paragraph (a) using that
assigned LD50 and taking as the mass of Substance A in the formula
the total of the masses of all substances whose actual LD50 is less
than or equal to the toxic limit, or
(A) determine the contributing number (CN) of each of the substances with
an LD50 less than or equal to the toxic limit using the formula
(C) obtain the LD50 of the mixture by dividing 1 by the number
T (LD50 of the mixture = 1 / T).
use the following calculations:
.
(B) combine the contributing numbers (CN) of each substance with an LD50
less than or equal to the toxic limit as
.
and
2.32 Determination of LC50 (dust, mist or vapour)
LC50 values for a substance in the form of a dust, mist or vapour or
for a mixture of substances in the form of a dust, mist or vapour must be
determined
(a) by using the LC50 values published in technical journals
or in government publications;
(b) in accordance with sections 2.6.2.2.4.2 to 2.6.2.2.4.7 of Chapter 2.6
of the UN Recommendations; or
(c) for a mixture of substances, in accordance with section 2.33.
2.33 Determination of LC50 (dust, mist or vapour) of a Mixture of
Substances
This section provides a method for making an acceptable approximation of the LC50
of a mixture of substances. The methods in paragraphs 2.32(a) and (b) are more
exact. SOR/2002-306
To determine the LC50 of a mixture of substances that are in the form
of a dust, mist or vapour, when the LC50 of each of the substances
is known, make the determination in accordance with section 2.17, except that
for a dust use 10 mg/L as the toxic limit and for a mist use 2 mg/L as the
toxic limit. For a substance in the form of vapour the toxic limit is the same
as for a gas, which is 5 000 mL/m3.
2.34 Determination of the Packing Group of a Mixture of Liquids with an
Inhalation Toxicity by Vapour
(1) The first step in determining the packing group of a mixture of
liquids with an inhalation toxicity by vapour when one or more of the
substances has an LC50 (vapour) less than or equal to 5 000 mL/m3,
and the LC50 of each substance is known, is to determine the
following data:
(a) determine the LC50 (vapour) for the mixture in accordance
with section 2.33;
(b) where Pi is the vapour pressure of the ith substance
in kPa at 20°C and an absolute pressure of 101.3 kPa, determinethe
volatility, Vi, of each substance in the mixture as
Vi = Pi multiplied by 106 then divided by
101.3;
(c) determine the ratio of the volatility of a substance to its LC50
for each substance with an LC50 less than or equal to 5 000 mL/m3
as
Ri = Vi divided by the LC50 of the ith
substance;
and
(d) set R equal to the sum of the Ri for each of the
substances with an LC50 less than or equal to 5 000 mL/m3
as
R = R1 + R2 + . + (as needed).
(2) Using the data determined in accordance with subsection (1), the
mixture is included in one of the following packing groups:
(a) Packing Group I, if
(i) R is greater than or equal to 10, and
(ii) the LC50 (mixture) is less than or equal to 1 000 mL/m3;
(b) Packing Group II, if
(i) R is greater than or equal to 1,
(ii) the LC50 (mixture) is less than or equal to 3 000 mL/m3,
and
(iii) the criteria for inclusion inPacking Group I are not met;
or
(c) Packing Group III, if
(i) R is greater than or equal to 0.2,
(ii) the LC50 (mixture) is less than or equal to 5 000 mL/m3,
and
(iii) the criteria for inclusion in Packing Group I or II are not met.
2.35 Determination of the Packing Group of a Mixture of Liquids with an
Inhalation Toxicity and an Unknown LC50
This section provides a method of directly determining the packing group of a
mixture of liquids that has an inhalation toxicity without requiring that the
exact LC50 be found.
(1) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group I if it meets the following criteria:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 1 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is diluted with 9 equal volumes of air to form a test atmosphere and 10 young
adult albino rats (5 male and 5 female) are exposed to the test atmosphere for
1 hour and observed for 14 days, the result is the death of 5 or more of the
animals within the 14-day observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 1 000 mL/m3 and a volatility greater than or equal to 10
times the mixture's LC50.
(2) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group II if it meets the following criteria and the
criteria for inclusion in Packing Group I are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 3 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when a sample of the vapour in equilibrium with the mixture at 20°C
is used to form a test atmosphere and 10 young adult albino rats (5 male and 5
female) are exposed to the test atmosphere for 1 hour and observed for 14 days,
the result is the death of 5 or more of the animals within the 14-day
observation period.
In this case the mixture is presumed to have an LC50 less than or
equal to 3 000 mL/m3 and a volatility greater than or equal to the
mixture's LC50.
(3) A mixture of liquids with an inhalation toxicity and an unknown LC50
is included in Packing Group III if it meets the following criteria and the
criteria for inclusion in Packing Group I or II are not met:
(a) when a sample of the mixture is vapourized and diluted with air to
create a test atmosphere of 5 000 mL/m3 and 10 young adult albino
rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and
observed for 14 days, the result is the death of 5 or more of the animals
within the 14-day observation period; and
(b) when the vapour pressure of the mixture is measured, the vapour
concentration is greater than or equal to 1 000 mL/m3.
In this case the mixture is presumed to have an LC50 less than or
equal to 5 000 mL/m3 and a volatility greater than or equal to 0.2
times the mixture's LC50.
(4) If only LC50 data relating to 4-hour exposures to dust or
mist are available, those figures can be multiplied by 4 and the result taken
as the LC50 data for 1 hour, that is LC50 4 hours (dust
or mist) multiplied by 4 is equivalent to LC50 1 hour.
(5) If only LC50 data relating to 4-hour exposures to vapour
are available, those figures can be multiplied by 2 and the result taken as the
LC50 data for 1 hour, that is LC50 4 hours (vapour)
multiplied by 2 is equivalent to LC50 1 hour.
