Infectious substances

An infectious substance, as defined under Section 1.4 of the TDG Regulations, is a substance known or reasonably believed to contain viable micro-organisms, such as viruses, bacteria, parasites, fungi, and other agents, that are known or reasonably believed to cause disease in humans or animals. Substances classified as infectious substances may include blood, tissue, organs, body fluids, or cultures that contain pathogenic microorganisms.

A list of infectious substances, such as Ebola virus or Herpes B virus, can be found in Part 2 of the TDG Regulations under Appendix 3.

Note: The table under Appendix 3 is not a complete list. If a substance is not listed in the table, it is still considered an infectious substance when it meets the definition above and exhibits characteristics similar to an infectious substance on the list, such as:

  • Severe Acute Respiratory Syndrome Associated Coronavirus (SARS-CoV)
  • Salmonella EntericaSPP
  • Hepatitis C virus, etc

In addition to the TDG Regulations, other government departments regulate infectious substances. The Public Health Agency of Canada (PHAC) administers regulations that apply to human pathogens in Canada, while the Canadian Food Inspection Agency (CFIA) regulates animal pathogens. In addition, provincial governments may have additional regulations that pertain to infectious substances.

As a consignor, you must comply with the requirements related to:

Note 1: Placarding applies to the person transporting the infectious substance or to the person loading the vehicle or large means of containment.

Note 2: The primary class placard must be displayed when infectious substances are transported unless the placarding exemption is used and no ERAP is required (Section 4.16.1).

Note 3: Placards and UN number are required when the shipment is transported in a large means of containment, and it requires an ERAP in accordance with Part 7 of the TDG Regulations.

Training

Always assume training is required. The only time training is not required is when you are using an exemption (i.e., special case) which exempts you from Part 6 of the TDG Regulations. You will find most exemptions in Part 1 of the TDG Regulations, from Sections 1.15 to 1.50.

Employers are responsible for issuing a training certificate once their employee has received adequate training. The certificate must contain all of the information required by Section 6.3 of the TDG Regulations. Even though there is no standard format, the TDG Directorate has a sample in the TDG Bulletin – TDG Training.

Classification

Infectious substances are classified as Class 6.2, Infectious Substances, and are assigned to a category (Category A or Category B) instead of a packing group.

Category A

Infectious substances included in Category A are infectious substances that are transported in a form such that, when it is released outside of its means of containment and there is physical contact with humans or animals, it is capable of causing permanent disability or life-threatening or fatal disease to humans or animals. The proper shipping name of a Category A infectious substance is, as appropriate:

  • UN2814 – INFECTIOUS SUBSTANCE, AFFECTING HUMANS
  • UN2900 – INFECTIOUS SUBSTANCE, AFFECTING ANIMALS only

Category B

Infectious substances included in Category B are infectious substances for which the likely consequences of an exposure during transport will not cause permanent disability and will not lead to fatality. The proper shipping name of a Category B infectious substance is:

  • UN3373 – BIOLOGICAL SUBSTANCE, CATEGORY B

Classification of patient specimens

The table below is a guide for classification of infectious substances contained in patient specimens.

Table 1 - Classification of human or animal specimens

Patient Specimen Condition There is no reason to believe the sample contains infectious substances (including routine tests) For the diagnosis of an infectious substances when there is suspicion of an infectious disease Category A infectious substance Category B infectious substance
Classification Human or animal specimens believed not to contain infectious substances exemption (Section 1.42 of the TDG Regulations) Regulated, as appropriate Fully regulated Class 6.2, Infectious Substances, UN3373, BIOLOGICAL SUBSTANCE, CATEGORY B exemption (Section 1.39 of the TDG Regulations)

No reason to believe

The term “no reason to believe” means that sufficient information is available and none of it suggests that the specimens could contain infectious substances included in Category A or B.

Professional judgment is required to determine whether there is no reason to believe a specimen contains an infectious substance. Factors such as the known medical history, symptoms and individual circumstances of the source, human or animal, and endemic local conditions should be considered.

For more details regarding the classification of infectious substances contained in patient specimens, please consult the document on classification of patient specimens.

Substances subject to the TDG Regulations

Any substance known or believed to contain infectious substances which meet the criteria of Category A or Category B is regulated under the TDG Regulations and must be assigned to UN2814, UN2900, UN3373, UN3291, or UN3549 as appropriate.

A list of regulated infectious substances can be found in Appendix 3 of Part 2 of the TDG Regulations. Note that this list is not exhaustive, but it serves as guide to classify pathogens.

Medical or Clinical Waste

Medical or clinical wastes include sharps, soiled linen, etc. They are derived from the medical treatment of humans, the veterinary treatment of animals or from bio-research. They can be assigned to:

  • UN2814 – INFECTIOUS SUBSTANCE, AFFECTING HUMANS, if they contain Category A infectious substances
  • UN2900 – INFECTIOUS SUBSTANCE, AFFECTING ANIMALS only, if they contain Category A infectious substances
  • UN3291– CLINICAL WASTE, UNSPECIFIED, N.O.S., (BIO) MEDICAL WASTE, N.O.S. or REGULATED MEDICAL WASTE, N.O.S., if:
    • the medical or clinical wastes contain Category B infectious substances, or
    • the medical or clinical waste are reasonably believed to have a low probability of containing infectious substances
  • UN3549 - MEDICAL WASTE, CATEGORY A, AFFECTING HUMANS, solid or MEDICAL WASTE, CATEGORY A, AFFECTING ANIMALS only, solid

Note: UN3549 is a new classification. This classification is for solid medical waste containing Category A infectious substances generated from the medical treatment of humans or veterinary treatment of animals; it shall not be used for waste from bio-research or liquid waste.

See Appendix for more information on transporting Ebola contaminated waste.

Biological Products

Biological products are derived from living organisms and are used to prevent, treat or diagnose disease in humans or animals. They are also used for development, experiment or investigation purposes and includes finished or unfinished products, live vaccines or attenuated live vaccines.

A biological product known or reasonably believed to contain a pathogen that meets the definition of a Category A or B infectious substance must be assigned to UN2814, UN2900, or UN3373, as appropriate.

Genetically Modified Microorganism and Organisms (GMMO and GMO)

GMMOs and GMOs which do not meet the definition of infectious substances are not subject to the TDG Regulations, unless they meet the criteria for inclusion in another class.

Patient Specimens

Patient specimens are those collected directly from humans or animals and include, for example, excreta, blood and its components, tissue and tissue fluids swabs, and body parts being transported for purposes such as research, diagnosis, investigational activities, disease treatment and prevention.

Cultures versus patient specimens

Infectious substances can be transported as cultures or contained in patient specimens. The risk of infection is higher in cultures, due to the high concentration of pathogens as opposed to patient specimens. Under certain conditions, infectious substances, classified as Category A, contained in patient specimens may be shipped as Category B.

However, some infectious substances must always be shipped as Category A regardless of their form, due to their pathogenicity. Table 2 provides a list of 19 infectious substances that must always be shipped as Category A. See Subsection 2.36 (3).

Table 2 - Infectious substances that are always shipped as Category A

Name of infectious substance UN number
  • Crimean-Congo Hemorrhagic fever virus;
  • Ebola virus;
  • Flexal virus;
  • Guanarito virus;
  • Hantaviruses causing hemorrhagic fever with renal syndrome;
  • Hantaviruses causing pulmonary syndrome;
  • Hendra virus;
  • Herpes B virus (Cercopithecine Herpesvirus-1);
  • Junin virus;
  • Kyasanur Forest virus;
  • Lassa virus;
  • Machupo virus;
  • Marburg virus;
  • Monkeypox virus;
  • Nipah virus;
  • Omsk hemorrhagic fever virus;
  • Russian Spring – Summer encephalitis virus;
  • Sabia virus; and
  • Variola (smallpox virus).
UN2814

Human or animal specimens are exempted from certain parts of the TDG Regulations if there is no reason to believe that the specimen contains an infectious substance. You can ship such specimens using the exemption under Section 1.42 of the TDG Regulations.

If the specimens are part of routine screening tests, then they may be shipped as per Section 1.42 of the TDG Regulations if a professional judgment concludes there is no reason to believe the patient could be contaminated with an infectious substance. This is also true for samples collected for the purpose of testing for a known infectious substance. For example, an employer may wish to screen all new employees for infectious diseases. In this case, you may ship the sample as “Exempt Human Specimen” if the medical professional concludes there is no reason to believe that the person has been in contact with an infectious substance.

Examples of specimens that may be transported under this section include:

  • blood or urine specimens to monitor cholesterol levels, blood sugar levels or hormone levels
  • specimens to determine the presence of drugs or alcohol for insurance or employment purposes
  • pregnancy test
  • biopsies to detect cancer

Doctor-patient confidentiality

There are no exemptions that apply to shipping samples that are known or suspected to contain infectious substances. However, the TDG Regulations do not require you to include a patient’s name or any personal reference when shipping infectious substances.

Shipping known or suspected infectious substances without complying with the TDG Regulations is an offence for which enforcement action is applicable.

Assistance to classify infectious substances

TDG Directorate is the authority with regards to the classification of infectious substances for transportation. However, you could contact the Public Health Agency of Canada (PHAC) or the Canadian Food Inspection Agency of Canada for assistance in the classification of infectious substances.

Note: Permitted packaging is dependent on classification of waste

Type P620 packaging

It is defined as a packaging that is in compliance with the requirements of the CAN/CGSB-43.125 standard for Type P620 packaging or, if it is manufactured outside Canada, is in compliance with the requirements of Chapter 6.3 and Packing Instruction P620 of the UN Recommendations and the national regulations of the country of manufacture.

This packaging is intended to transport an infectious substance of Category A in a form of culture or infectious substance of Category A meeting the requirements of Subsection 2.36 (3) of the TDG Regulations. However, as it is the highest integrity packaging, this packaging can also be used to transport Category B infectious substances and clinical, (bio) medical or regulated waste.

You will find the requirements for the design, testing and marking of Type P620 packaging in Part I of the CAN/CGSB-43.125 standard. Facilities that manufacture type P620 packaging in Canada must be registered with Transport Canada and must have their packaging design registered with Transport Canada. The CAN/CGSB-43.125 standard now requires the periodic retest of a Type P620 packaging design every five years.

Identify a Type P620 packaging

A Type P620 packaging will have a UN marking on the outer packaging as set out in Section 5.1 of the CAN/CGSB-43.125 standard. For example:

4G/CLASS 6.2/21
CAN/ABC 8-9999

 

Table 4 – Description of the UN packaging code and symbol

Code or symbol Description
United Nations packaging symbol.

4G
or
4GU
or

Packaging code (in this example, 4G represents a fiberboard box).

The "U" indicates the packaging is a special packaging which meets more stringent requirements.

The "W" indicates the packaging is manufactured to a different specification than the CAN/CGSB-43.125 standard but is equivalent to a packaging that conforms to the requirements of the standard.

CLASS 6.2 The text "CLASS 6.2" means that this type of container is suitable for Class 6.2 infectious substances.
21 The last two digits of the year of manufacture.
CAN The country authorizing the allocation of the marking.
ABC 8-9999 The name or symbol of the manufacturer and other identification of the container as specified by the country authorizing the allocation of the mark (e.g., design registration number).

A Type P620 packaging shall consist of:

  1. inner packagings comprising:
    • leakproof primary receptacle(s)
    • leakproof secondary inner packaging(s)
  2. a rigid outer packaging of adequate strength for its capacity, mass and intended use of which the smallest external dimension is at least 100 mm. The outer packaging shall be selected from Table 1 of the CAN/CGSB-43.125 standard.

For liquid infectious substances, an absorbent material must be placed between the primary receptacle(s) and the secondary inner packaging and in sufficient quantity to absorb the entire content of the primary receptacle(s).

The primary receptacle(s) of a type P620 packaging cannot be reused. The secondary inner packaging or outer packaging of a type P620 packaging may be reused if there is no visible contamination, damage or defects that may render the packaging unsafe for transport.

Example of a Type P620 packaging

Figure 1: Figure provided by IATA, Montreal, Canada (modified by the TDG Directorate)
Figure 1 - Text version

Type P620 packaging, which is a triple packaging system.

The outer packaging is a UN specification box, with UN specification marking. The box is also marked with a Class 6.2 infectious substance label. Next to label is the shipping name "infectious substance affecting humans" and the UN number. There are also labels for the consignor (i.e. shipper) and consignee and a label for the responsible person that includes their telephone number. Finally, the outer packaging is labelled with an orientation label, which is two arrows pointing up. These arrows are only required for Air and Marine transport when the primary receptacle exceeds 50 ml or 50 g.

Placed inside the outer package is a secondary packaging, which is leakproof. This secondary packaging is cylindrical in shape and has a screw-on cap. The secondary packaging is affixed with a label that includes an itemized list of its contents.

Finally, inside the secondary packaging is the leakproof primary receptacle, which is a test tube. The test tube is surrounded by absorbent material.

Type P650 packaging

A Type P650 packaging is defined as a packaging that is in compliance with the requirements of the CAN/CGSB-43.125 standard for Type P650 packaging or, if it is manufactured outside Canada, is in compliance with the requirements of Packing Instruction P650 of the UN Recommendations and the national regulations of the country of manufacture.

A Type P650 packaging is intended for the transport of UN3373 - Category B infectious substances. However, this packaging can also be used to transport clinical, (bio) medical or regulated waste UN3291.

You will find the requirements for the design, testing and marking of Type P650 packaging in the CAN/CGSB-43.125 standard.

Facilities that manufacture type P650 packaging in Canada are not required to be registered with Transport Canada, however, a Type P650 packaging design report must be prepared and retained by the manufacturer in accordance with Annex A of the Standard to demonstrate compliance with the Standard.

Identify a Type P650 packaging

The marking required on the outer packaging of a Type P650 packaging is specified in Section 5.2 of the CAN/CGSB-43.125 standard.

The Category B mark, as per Section 4.22.1, must be displayed on the outside of a Type P650 packaging to demonstrate compliance with the CAN/CGSB-43.125 Standard.

The marking shall be in the form of a square on point with each side having a length of at least 50 mm. The width of the line shall be at least 2 mm and the letters and numbers shall be at least 6 mm high. The illustration below shows the marking for Type P650 packaging.

marking required on a Type P650 packaging
 

Note: The marking required on a Type P650 packaging is a hybrid marking as it is used as the packaging compliance mark and the dangerous goods safety mark, (Category B Mark) found in the Appendix of Part 4 of the TDG Regulations.

Therefore, having an empty packaging with this mark displayed on it could be considered misleading as it could indicate that a person is transporting UN3373, BIOLOGICAL SUBSTANCE, CATEGORY B. However, Special Provision 165 of the TDG Regulations allows the use of this mark even if the packaging is empty.

A Type P650 packaging shall consist of:

  1. inner packagings comprising:
    • primary receptacle(s) (leakproof or siftproof)
    • secondary packaging(s) (leakproof or siftproof)
  2. an outer packaging of which the smallest external dimension is at least 100 mm

Note: Either the secondary packaging(s) or the outer packaging shall be rigid.

When transporting liquid infectious substances, absorbent material must be placed between the primary receptacle(s) and the secondary packaging in sufficient quantity to absorb the entire contents of the primary receptacle(s) so that any release of the liquid substance will not compromise the integrity of the cushioning material or of the outer packaging.

When transporting solid infectious substances, if there is any doubt as to whether or not residual liquid may be present in the primary receptacle during transport then a packaging suitable for liquids, including absorbent materials, shall be used.

The primary receptacle(s) of a type P650 packaging cannot be reused. The secondary inner packaging or outer packaging of a type P650 packaging may be reused if there is no visible contamination, damage or defects that may render the packaging unsafe for transport.

Examples of a Type P650 packaging

Figure 2 - Text version

Type P650 packaging.

The outer packaging is a box that is labelled with the Category B mark, which is a square on point mark with "UN3373" written inside. Next to label is the shipping name "Biological Substances Category B". Also written on the box is the 24 hour telephone number. There are also labels for the consignor (i.e. shipper) and consignee.

Placed inside the outer package is a secondary packaging, which is leakproof or siftproof. This secondary packaging is cylindrical in shape and has a screw-on cap. The secondary packaging is affixed with a label that includes an itemized list of its contents.

Inside the secondary receptacle is a rack-type holder made from styrofoam or sponge. This rack is holding the primary receptacles, which are test tubes and surrounded by cushioning and absorbent material.

Documentation

Shipping document

You must prepare a shipping document if you are shipping a Category A infectious substance (UN2814 or UN2900).

However, you will not need a shipping document if you are shipping a Category B infectious substance (UN3373) in accordance with the exemption set out in Section 1.39 of the TDG Regulations. Don’t forget that there are certain Category A infectious substances than can be shipped as a Category B. You need to refer to Subsections 2.36(2) and (3) of the TDG Regulations to verify which Category A infectious substances can be shipped as a Category B.

To learn more, or to view a sample shipping document, consult the TDG Bulletin – Shipping Documents.

Labels and placards

The dangerous goods safety marks that must be displayed on a small means of containment depend on the type of infectious substance you are shipping.

Category A

If you are shipping a Category A, you must label the package with an infectious substance label. This label is illustrated in the Appendix to Part 4 of the TDG Regulations.

Infectious substance label - Text version

Class 6.2, Infectious Substances label (square on point ). This label has the biohazard symbol at the top and the number 6 at the bottom. In the center of the label there is bilingual text that reads as follows:

Placards on the vehicle

As per Subsection 4.15(1) of the TDG Regulations, placards are required in the following instances:

The infectious substances are transported in a large means of containment. By definition, a large means of containment is a means of containment with a capacity greater than 450 L (i.e., a delivery truck). However, Section 4.16.1 provides a placarding exemption for dangerous goods having a gross mass of 500 kg or less.

Paragraph 7.2(1)(g) of the TDG Regulations refers to a list of 16 infectious substances that require an Emergency Response Assistance Plan (ERAP). For those situations, the placards and UN number must be displayed. The placarding exemption found in Section 4.16.1 cannot be used when an ERAP is required.

The person who loads the vehicle or large means of containment is responsible for displaying the placards. This person could be either the consignor (i.e., shipper) or the carrier. Once the vehicle leaves the site, the carrier is responsible for placarding.

Exemptions and special provisions

There are two exemptions for shipping infectious substances or potential infectious substances. Like most exemptions, you can find them in Part 1 of the TDG Regulations.

  • Section 1.39 – Class 6.2, Infectious Substances, UN3373, BIOLOGICAL SUBSTANCE, CATEGORY B exemption
  • Section 1.42.3 – Medical or Clinical Waste

In order to use an exemption, you must comply with all conditions listed in the exemption. If you can’t, then you need to ship your infectious substances fully regulated.

Special provisions that only apply to infectious substances

Special Provision 84 states that infectious substances listed in Paragraph 7.2(1)(g) of the TDG Regulations require an emergency response assistance plan.

Special Provision 128 exempts decontaminated medical or clinical waste that from all parts of the TDG Regulations (except Parts 1 and 2) under certain conditions.

Special Provision 164 allows for the transport of other dangerous goods in the same small means of containment with UN2814, UN2900 or UN3373, if they are necessary for maintaining the viability or stability of the dangerous goods, for preventing their degradation or for neutralizing the hazards that they represent.

Special Provision 165 of the TDG Regulations allows the use of the CATEGORY B mark even if the packaging is empty.

Marine shipments

When shipping by vessel, you must refer to Part 11 of the TDG Regulations.

Air shipments

When shipping by air, you must refer to Part 12 of the TDG Regulations.

For liquid infectious substances transported by aircraft only, Type P650 packages must undergo the internal pressure test in accordance with Section 7.5 of the CAN/CGSB-43.125 standard.

Domestic transport

When transporting infectious substances domestically by air, Part 12 of the TDG Regulations requires you to comply with the ICAO Technical Instructions and Subsection 12.1(1) of the TDG Regulations.

International transport

When transporting infectious substances internationally by air (from or to Canada), Part 12 of the TDG Regulations requires you to comply with the ICAO Technical Instructions and Subsection 12.1(1) of the TDG Regulations.

Appendix - Transporting Ebola contaminated waste

Transport Canada regulates the Ebola virus as an infectious substance under the TDG Regulations. Following the Ebola Outbreak of 2014-2016, a new UN number for solid infectious substance waste of Category A (UN 3549), as well as two associated packing instructions (P622 and LP622) were introduced into the 21st edition of the UN Model Regulations.

Prior to this, there were no approved packagings suitable for transporting the large volumes of Category A waste that are generated from caring for a patient suspected or known to be contaminated with the Ebola virus. Transport Canada will be introducing the UN3549 classification into the TDG Regulations. The packaging requirements for UN3549 were introduced into the 2021 edition of the CAN/CGSB 43.125 standard.

Anyone handling, offering for transport or transporting this infectious substance by road, rail, marine or air must comply with the TDG Regulations:

  • Part 3 requires the consignment to be accompanied by a shipping document
  • Part 4 requires the means of containment to display the appropriate safety marks
  • Part 5 and the requirements listed in the CAN/CGSB 43.125 standard
  • Part 6 requires anyone who handles, offers for transport or transports the infectious substances to be properly trained and hold a training certificate
  • Part 7 requires anyone who offers for transport or imports any quantity of the Class 6.2 infectious substances listed in Paragraph 7.2(1)(g) to have an approved emergency response assistance plan (ERAP). The Ebola virus is listed in Schedule 4 of the Human Pathogens and Toxins Act
    • It is the person who offers for transport or imports Ebola contaminated waste who must apply for an ERAP
    • Transport Canada will issue a reference number in writing when it approves the ERAP
    • The ERAP reference number and activation telephone number must appear on the shipping document
    • A person may request written permission to use another person’s approved ERAP if it applies to the dangerous goods, the mode of transport, the means of containment and the geographical area. The person who holds the approved ERAP must also agree to respond to an emergency on behalf of the other person

Note: The transport of deceased bodies contaminated with the Ebola virus is not regulated under the TDG Regulations.
