Transportation of Dangerous Goods (TDG)


The Transportation of Dangerous Goods (TDG) is an area under strict regulations in Quebec and Canada. The objective of this regulation is to promote safety in the transportation of dangerous goods by road, rail, sea or air. Anyone who ships, transports, delivers, receives, handles or writes up transportation documentation dangerous goods must follow a TDG formation given by EHS in order to obtain a TDG certificate.

EHS provides the following TDG training:

  • TDG General
  • Introduction to Transportation of Dangerous Goods – General (only available on Moodle)
  • TDG Class 7 – Radioactive Materials
  • TDG Class 6.2 – Biological/Infectious Substances

Please check the following link to get more details about EHS training offered at Concordia and this page for Procedures & guidelines for transfer of biological material outside of Concordia.

Transport between buildings

Unless the specified substance is exempt or is present in a limited quantity, any transportation of hazardous material by road vehicle between buildings or campuses related to University activities must be performed following the requirements of the TDG regulations.

The TDG classification must include the following information in this order:

  • UN number
  • Proper Shipping name
  • Class (& subsidiary class(es))
  • packing groups, compatibility groups or categories

The dangerous good are separated into 9 classes according to the type of hazard they represent:

  • Class 1: Explosives
  • Class 2: Gases
  • Class 3: Flammable Liquids
  • Class 4: Flammable Solids
  • Class 5: Oxidizers
  • Class 6: Poisons
  • Class 7: Radioactive Materials
  • Class 8: Corrosives
  • Class 9: Miscellaneous

Public transportation (STM or shuttle bus) must not be used for the transportation of hazardous materials between campuses. To ship dangerous goods between campuses, please make arrangements with Distribution Services.

Transport within buildings

  • The following precautions are to be followed when transporting chemicals (or any other hazardous substances) within University buildings in order to protect the University community.
  • Chemicals should be transported using a cart or by hand using a secondary container such as a chemical resistant bucket.
  • Always use a sturdy cart with a low center of gravity and spill tray. Carts with large wheels are best to navigate irregularities in floors and over the elevator door ledge.
  • Use secondary containers to protect the primary container from shock during any sudden change of movement. A secondary containment is important when chemicals are moved through public areas such as hallways or elevators, where the effects of a spill would be more severe.
  • Freight elevators must be used for moving chemicals and biological materials between floors. Passenger elevators must not be used for this purpose.
  • Do not transport incompatible chemicals together on the same cart.
  • All chemical containers require a label identifying the contents in accordance with WHMIS regulation.
