Transporting dangerous goods: key rules to remember

Ch. 10 Safe transport of goods (pp. 151–152)

  • Dangerous goods rules are harmonized across Canada and apply to air, marine, rail and road transport.
  • The person in charge must report immediately any release of dangerous goods, a reportable dangerous occurrence or collision, the loss or theft of certain goods, and a delay in delivering certain explosives.
  • Anyone who handles, offers or transports dangerous goods must be trained or work under the direct supervision of a trained person.
  • The employer must ensure training; the trained person receives a Transportation of Dangerous Goods certificate, renewed every 36 months.
  • Consignor (shipper): supplies the safety marks and product identification number, and the shipping document or waste manifest, to the first carrier.
  • Carrier: displays the right safety marks, replaces lost or damaged ones, makes sure documents travel with the load, segregates loads, refuses non-compliant shipments, keeps documents for two years.
  • Consignee: completes and forwards waste documents, and meets consignor requirements when returning uncleaned empty containers or vehicles.

Classifying and safety marks (pp. 152–153)

  • Nine classes: 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids, 5 oxidizing substances, 6 toxic and infectious, 7 radioactive, 8 corrosives, 9 miscellaneous.
  • Labels go on packages, cylinders and drums; placards go on large containers (over 450 L) and transport units.
  • A UN/product identification number is four digits (gasoline is UN1203) and is required for trailerload, truckload or bulk quantities.
  • Dangerous goods routes in cities, towns and villages are set by civic bylaw and posted with signs.

Documentation (pp. 153–154)

  • The consignor makes sure the shipping document is complete, in the required order, signed and given to the first carrier.
  • Driver in the cab: one copy within reach or in a pocket on the driver's door. Driver out of the cab: on the driver's seat or in the door pocket.
  • A detached trailer with dangerous goods left in a parking area: leave a copy with the person in charge of the area.
  • Otherwise keep the document in an accessible, identifiable waterproof container attached to the unit.
  • After unloading, if residue still creates a hazard, the document is marked "RESIDUE – LAST CONTAINED" until the unit is reloaded or cleaned and purged.
  • Waste dangerous goods travel with the prescribed manifest.
  • Placarded vehicles must stop at uncontrolled railway crossings.
  • A placarded vehicle cannot be used for a road test.
