Welcome back to the Regulatory Helpdesk where we answer your dangerous goods & hazmat questions. Here are some highlights from our helpdesk last week. Check back weekly, the helpdesk rarely hears the same question twice.
WHMIS Label Size Requirements
Q. Is there were size requirements for WHMIS labels?
A. No, the HPR does not mandate a size requirement other than saying it has to be legible. But, what does legible mean? As a general rule of thumb, which we have developed from reviewing many different labeling regulations is 10 mm for one side of the pictogram, and 2 mm for the font size (1.6 mm for a worst-case scenario).
IATA Special Provision
Q. What does IATA’s Special Provision A191 mean?
A. It was determined that SP A191 means if you have a manufactured article with less than 5 kg of mercury in it (like a thermometer) then you don’t need the Class 6.1 label for mercury’s subsidiary hazard and you don’t have to list the 6.1 subsidiary hazard on the shipper’s declaration. From what we can tell that only applies to UN3506 which is Mercury contained in manufactured articles.
Quantity Limits – TDG (Canada)
Q: What does the quantity limit in TDG Columns 8 & 9 represent in terms of Passenger conveyance restrictions- package, consignment, …?

So, you want to bend the rules? What happens when you have a scenario where following the regulations to ship your dangerous goods becomes impractical to the point of impossibility?
This blog entry will speak to what the process is for applying for an Equivalency Certificate in Canada as per the Transportation of Dangerous Goods Clear Language Regulations.
Generally when people ship dangerous goods, the process becomes a matter of reading and complying with everything the regulations state. However, below are some scenarios where following exactly what the regulations state is… shall we say… less than ideal.
Al wants to ship some large batteries for equipment within Canada with classification:
UN 2794, Batteries, Wet, Filled With Acid, Class 8, P.G. III
His dilemma is that when a new battery is commissioned, the outer package is generally discarded due to space limitations. In many cases these batteries were installed prior to the packaging requirements of Part 5 of the TDG Regulations.
Al wants to ship this without UN approved packaging.
Bill wants to ship a MRI machine that contains liquid helium, classification:
UN 1963, Helium, refrigerated liquid, Class 2.2
His dilemma is that his MRI machine is what contains the Helium and it is not in an approved means of containment. He requires the helium to remain in his equipment during transport in order to keep the magnet cool.
