Recent inspections conducted across Canada by various Transportation of Dangerous Goods Inspectors of Transport Canada have discovered the use of non-acceptable cylinders used for fire extinguishers, refrigerant gas recovery and scuba diving.

You are advised that any cylinder manufactured after December 31, 1992, and used to contain dangerous goods in Canada, must display a Transport Canada (TC) specification mark. The "TC" specification mark indicates that the cylinder was manufactured, inspected and tested in accordance with Transports Canada safety standards. Presently, these safety standards differ from those found in the United States.

Under section 8 of the Transportation of Dangerous Goods Act 1992 it is an offence to "sell, offer for sale, deliver, distribute, import or use a standardized means of containment unless it displays all apllicable prescribed safety marks".

Many of the cylinder manufacturers construct cylinders that meet both the Transport Canada (TC), and the United States (DOT) safety standards.  These dual specification cylinders should be requested at time of purchase.

Your co-operation in this endeavour is appreciated. If you or any of your association members have any questions please contact our Region Office at (514) 283-5722 or by email at gagnoh@tc.gc.ca.
