Determining if an Emergency Response Assistance Plan (ERAP) is required

An Emergency Response Assistance Plan (ERAP) describes what to do in the event of a transportation incident involving certain higher-risk dangerous goods. These plans assist local emergency responders by providing them with technical experts and special emergency response personnel at the scene of an incident.

Overview of the Regulations

The Transportation of Dangerous Goods Act, 1992 (TDG Act) and Transportation of Dangerous Goods Regulations (TDG Regulations) require you to have an ERAP in cases where responding to an incident will involve special expertise and response equipment.

  • Part 7 of the TDG Act requires that a person have an approved ERAP before offering for transport or importing certain dangerous goods
  • Part 7 and column 7 of Schedule 1 of the TDG Regulations set out the dangerous goods and their concentration or quantity for which an ERAP is required

Determining if you need an ERAP

Use the following questions to help you determine whether you need an ERAP for a shipment of dangerous goods.

7.1 (1) - Single means of containment (MOC) exceeds ERAP limit

Does the quantity in a single MOC (small or large) exceed the ERAP limit in column 7 of Schedule 1?

  • Note: There may be more than one MOC present

If yes: ERAP required. (Reference: Subsection 7.1 (8) of the TDG Regulations)

If no: See 7.1 (2) - Accumulation of MOCs (small or large)

7.1 (2) - Accumulation of MOCs (small or large)

Do the dangerous goods meet all three of the following conditions?

  1. They have the same United Nations (UN) number.
  2. They are contained in multiple MOCs (can be a combination of both small and large MOCs).
  3. They are included in one of the following classes:
    • Class 3 (6.1)
    • Class 4
    • Class 5.2 Organic Peroxides, Type B or C
    • Class 6.1 PG1

If yes: ERAP required if the total quantity of all MOCs (small and large) exceeds the ERAP index. (Reference: Subsection 7.1 (8) of the TDG Regulations)

If no: See 7.1 (3) - Accumulation of large MOC

7.1 (3) - Accumulation of large MOC

Do the dangerous goods meet both of the following conditions?

  1. They have the same UN number.
  2. They are contained in multiple large MOCs.

If yes: ERAP required if the total quantity of all the large MOCs exceeds the ERAP index. (Reference: Subsection 7.1 (8) of the TDG Regulations)

If no: See 7.1 (4) - Explosives

7.1 (4) - Explosives

Are the dangerous goods included in Class 1? Note:

  • Only consider explosives that have an ERAP index
  • There may be one or more UN numbers
  • There may be one or more MOCs

If yes: ERAP required if the total quantity of all explosives exceeds the ERAP index for one of the explosives. (Reference: Subsection 7.1 (8) of the TDG Regulations)

Note: 1 kg of Net Explosives Quantity (NEQ) equals 100 articles. Use this conversion for a mixture of articles (for example, Special Provision 86) and regular explosives.

If no: See 7.1 (5) - Class 2 Gases – Interconnected MOCs

7.1 (5) - Class 2 Gases, - Interconnected MOCs

Do the dangerous goods meet all four of the following conditions?

  1. They are included in Class 2
  2. They have the same UN number
  3. They are contained in multiple MOCs, each:
    1. with a capacity greater than 225 L, and
    2. interconnected through a piping arrangement
  4. The MOCs are permanently mounted on a structural frame for transport

If yes: ERAP required if the total capacity of all the interconnected MOCs exceeds the ERAP index. (Reference: Subsection 7.1 (8) of the TDG Regulations.)

If no: See 7.1 (6) - Rail tank cars.

7.1 (6) - Rail tank cars

The shipment includes one or more rail cars containing:

If yes: ERAP required if the quantity of a single rail tank car exceeds 10,000 L. (Reference: Subsection 7.1 (8) of the TDG Regulations.)

If no: See 7.1 (7) - Class 6.2 Infectious Substances.

7.1 (7) - Class 6.2, Infectious Substances

Are any of the following infectious substances being transported?

  1. Crimean-Congo Hemorrhagic fever virus
  2. Ebola virus
  3. foot and mouth virus or cultures
  4. Guanarito virus
  5. Hendra virus
  6. Herpes B virus (Cercopithicene Herpesvirus-1) or cultures
  7. Junin virus
  8. Kyasanur Forest virus
  9. Lassa virus
  10. Machupo virus
  11. Marburg virus
  12. Nipah virus
  13. Omsk hemorrhagic fever virus
  14. Russian Spring-Summer encephalitis virus
  15. Sabia virus
  16. Variola (smallpox virus)

If yes: ERAP required.

If no, and if you answered no to questions 7.1 (1) to 7.1 (7): You do not require an ERAP.
