Frequently Asked Questions
Transport
Canada has developed a comprehensive list of frequently asked questions.
Visit these three Web sites:
Jacques Whitford is currently providing this training to audiences across the country. Questions not answered in the Transport Canada FAQ section will be posted here with responses.
What is the unit of measure for the value in column 6, schedule 1? For example, UN1978 Propane has a value of 0.125 but no reference to units of measure.
The Explosive Limit and Limited Quantity Index value found in column 6 of schedule 1 gives the quantity of dangerous goods at or below which the dangerous goods may be handled. The units of measure vary based on the physical state of the dangerous good: solids are expressed in kilograms, liquids are expressed in litres, and gases (in gaseous or liquified forms) are also expressed in litres.
How do I determine the maximum weight my vehicle can carry? Can you provide me with an example?
To determine the how much weight your vehicle can safely carry, subtract the net weight of the vehicle (found in your owner's manual) from the GVWR (found on the driver's door post).
For example, here is the load calculation for a 1364kg van:
2909kg (GVWR) - 1364kg (van) = 1545kg (maximum load)
If I need to refill an 80 lb forklift propane cylinder for work purposes, do I have to comply with the Act, fill out a dangerous goods document and affix appropriate labelling?
Yes, the TDG Act and Regulations apply to the transportation of a propane
cylinder of that size. One must comply with all the requirements of
the TDG Regulations: safety marks, shipping document, certificate
of training, etc.
Must a placard/label indicate the division of the dangerous good? For example, if I were to label a container that held a flammable gas, does the label have to show 2.1, or is "2" adequate?
In this case, 2 is adequate - as long as it is on a red background. However,
these requirements change depending on this type of dangerous goods. For
example, a class 2.2 label or placard must be identified as such. Please
refer to Part
4 of the TDG Regulations for more information.
My company receives bladders of Sodium Hydroxide containing 1,000 L of the chemical. We typically empty the bladders, roll them up and ship them back to the supplier. Do these empty bladders fall under the Act? If so, what are we required to do?
Yes, the empty bladders fall under the TDG Act and Regulations. A general rule of thumb is that if the containers still hold dangerous goods and there is still a danger present in the means of containment, the containers must be transported in accordance with the TDG Act and Regulations. You must comply with all the requirements of the TDG Regulations. On the shipping document, you can specify that the containers hold "Residue - Last Contained: Name of Chemical". For more information, please refer to sub-section 3.5(4) of the TDG Regulations.
How many labels are required on a small means of containment such as a box?
One label must be displayed for the primary class and one for each subsidiary class. For more information, please refer to section 4.10 of the TDG Regulations.
