An Emergency Response Assistance Plan (ERAP) is required in instances where
dangerous goods are potentially very hazardous when transported in moderate or large
quantities.
The ERAPs are not required for all dangerous goods. They are required only for the Dangerous Goods listed in Column 7 of Schedule I of the TDG Regulations. Generally speaking these are dangerous goods which are more harmful than others, and may present wide spread hazards in the event of an accident.
Part 7 of the TDG Regulations requires consignors and importers of dangerous goods to register an ERAP if necessary.
An ERAP is required for the following circumstances:
- A quantity of dangerous goods having the same UN number in one means of
containment. If the quantity of dangerous goods exceeds the ERAP limit, an ERAP
is required regardless of the size of the means of containment;
- An accumulation of dangerous goods in means of containment that each have a
capacity greater than 10 percent of the ERAP limit in Column 7 of Schedule 1; and
- A quantity of one or more dangerous goods from one of the following classes that
are in one or more means of containment:
Class 1 Explosives
- Class 3, Flammable Liquids with a subsidiary class of 6.1, Toxic Substances
- Class 4, Flammable Solids
- Class 5.2, Organic Peroxides, that are Type B or Type C
- Class 6.1, Toxic Substances, Packing Group I
