Transportation of Dangerous Goods (TDG) CCOHS



Course Details

Course Description

People who handle, offer for transport, or transport (i.e. handle, ship, carry or receive) dangerous goods must be adequately trained and hold a TDG Certificate of Training for their work.

This course consists of eight modules that provide detailed descriptions of all aspects of the TDG system for transportation of dangerous goods by road. The course will help employers, owners, managers, supervisors, TDG coordinators, and those who have responsibilities for determining the training requirements for employees who will be handling dangerous goods, meet their responsibilities to ensure that all work involving dangerous goods is done properly according to the requirements of the TDG Act and Regulations.

Examples and quizzes reinforce learning and each module has a self-assessment to test understanding of the material.

A record of completion is provided by CCOHS upon successful completion of the final exam. A formal TDG Certificate of Training is issued by the employer when they determine their employee has a sound knowledge of all the topics and has received workplace specific training that directly relates to their duties with dangerous goods. The course was developed by CCOHS.

Topics include 8 modules:

  1. Overview: Provides an introduction and overview of the Transportation of Dangerous Goods (TDG) Act and Regulations. Includes information on training, classification, documentation, safety marks, means of containment, and emergencies.

The information is based on the requirements in the Transportation of Dangerous Goods (TDG) Act and Regulations.
