The two Equivalency Certificates SH 10006 - Ren 5 and SH6171 - Ren 9, which allow placards on only the two long sides of a nurse tank, will expire on May 31, 2017.

Beginning June 1, 2017, nurse tanks will require placards identifying that it is carrying ammonia (UN 1005) on all four sides in a way that complies with Part 4 (Dangerous Goods Safety Marks) of the Transportation of Dangerous Goods (TDG) regulations.

Subsection (3) of Section 4.7 in the TDG regulations indicates that each side of the placard must be at least 250 mm in length. If a placard that size cannot be displayed properly due to the irregular size or shape of the tank, then a smaller placard can be used as long as the length of the sides is not less than 100 mm. While a placard of 100 mm is considered to comply with the TDG regulation, it will be up to the tank owner to demonstrate that a larger placard size is not feasible.
