This is an update to my post of a few weeks ago. I called a friend who lives near the BC-US border who spoke to his local propane supplier who told him that Transport Canada recently changed their regulations so that non Canadian certified propane tanks that meet US DOT standards can now be recertified and refilled in Canada. To verify this was correct I called a Transport Canada inspector of dangerous goods who confirmed that this was correct. So I then called my local propane supplier who had a few months ago declined to recertify my US DOT tank (he had done the other tank last year - presumably without thinking or checking) and told him what I had been told. even then I had to wait two weeks while he got written confirmation from Transport Canada. When I went in to collect my recertified and refilled tank he was gushing with enthusiasm for the quality and durability of the Worthington made aluminium tank with pressure gauge, rather ironic in view of the previous rejection and willingness to condemn to the scrap yard!
The tank now bears the recertification date and identifier of the recertifying dealer and is good for another 10 years.
To quote from the TC regulations:
CSA*B340 specifies the selection and use requirements for cylinder and tube specifications that are authorised for use in Canada by Subsection 5.10(2) of the TDG Regulations. This includes cylinders and tubes that have been in use in Canada for many years and that belong to one of the following groups of specifications:
* Cylinders and tubes that have been manufactured in accordance with CSA*B339. These cylinders and tubes are commonly referred to as “TC specification” cylinders and tubes because the prefix marked before the specification designation is “TC”.
* Cylinders and tubes that have been manufactured in accordance with the U.S. Department of Transportation’s Hazardous Materials Regulations entitled Title*49 of the Code of Federal Regulations of the United States (49*CFR). These cylinders and tubes are commonly referred to as “DOT specification” cylinders and tubes because the prefix marked before the specification designation is “DOT”.
