The short answer to this question is every 3 years.
However, since the new TDG Clear Language Regulations
came into effect on August 15, 2002, everybody who
requires training needs to have a TDG Clear
this means that anybody who requires TDG training needs
to have a valid TDG Clear Language certificate issued
after August 15, 2002.
AND ... It is now
well past the official 3-year renewal
date (August 15, 2005), so everyone who was trained previously should
be re-trained and issued a new 3-year TDG
However, the 3-year rule is
not the only condition of re-training.
According to the TDG Regulations, a TDG certificate is
not transferable between employers. This means
that if a trainee changes employers, he or she will need
to be re-certified by the new employer and possess a
training certificate with the new employer's name and
Change in job function
Also, if an employee changes job functions and he or she
has not been previously trained for that specific job,
then he or she requires re-training.
For example: Donna is a documentation clerk who
routinely fills out shipping documents. Her employer has
provided her with TDG training for her specific job function.
Last week, Donna received a promotion and is now driving
and delivering the dangerous goods. She did not
previously receive training on how to deliver, ship or
transport the dangerous goods. Donna's employer must now
re-train her based on her new job function.
To avoid re-training too
often, many employers choose to train their staff on
all aspects of transporting dangerous goods.
However, be aware that if your employees do not practice
or use the knowledge often, they may easily
forget. Make sure you are diligent in ensuring that your
staff are properly trained at all times.
