Emergency response assistance plan (s. 7)

  • Above quantities or concentrations set by regulation, a person may not import, offer for transport, handle or transport dangerous goods without an ERAP approved by the Minister in advance.
  • An ERAP sets out what to do in response to an actual or anticipated release of the goods during handling or transport that endangers, or could endanger, public safety.
  • The Minister approves an ERAP for a set period when satisfied it can be carried out and will be effective.

When an approved ERAP is required (s. 7.2)

  • An ERAP is required when goods with the same UN number in a single means of containment exceed the ERAP index in column 7 of Schedule 1.
  • Several large means of containment on one road or railway vehicle with the same UN number need an ERAP when their total exceeds the ERAP index.
  • Explosives on a road or railway vehicle need an ERAP when the total exceeds the lowest ERAP index of the explosives carried.
  • Certain flammable liquids carried by rail in a tank car over 10 000 L need an ERAP, for example gasoline, diesel fuel, crude oil and ethanol over 24%.
  • Any quantity of a Risk Group 4 human pathogen needs an ERAP.

ERAP on the shipping document (s. 3.5)

  • When an ERAP is required, the shipping document shows the ERAP reference number issued by Transport Canada and the ERAP telephone number.

ERAP and marks (ss. 4.15.1–4.15.2, 4.16)

  • Goods that require an ERAP must show their UN number on the large means of containment.
  • Goods that require an ERAP cannot use the DANGER placard or the 500 kg placard exemption.

Implementing an ERAP (s. 7.8)

  • A plan holder implements an approved ERAP at tier 1 or tier 2 in response to a release or anticipated release.
  • Tier 1: give technical or emergency response advice as soon as possible and monitor the response remotely.
  • Tier 2: give advice, monitor the response and send ERAP emergency response resources to the scene.
  • No one may prevent an ERAP holder from taking emergency measures.

ERAP program
