We need to train our workers about how to handle and transport hazardous materials safely. This is called Transportation of Dangerous Goods (TDG) Awareness training. It is important for employers to decide who needs to be trained and how much they need to learn. Only the employer can give the certificate saying that the worker is trained.
Workers are considered adequately trained when they know all about the dangerous goods they will handle and how to do their job safely. It is against the law to let workers do TDG work without training, unless they are directly supervised by someone who is trained.
Employers don't need to be certified unless they themselves are doing the TDG work or supervising someone who needs the training.
Only an employer can give a training certificate to a worker, to show that they are qualified to do their job safely. The certificate is good for 3 years and only applies to that employer. If the worker changes jobs, they need to get re-certified by their new employer.
