Explanatory Note

This Equivalency Certificate authorizes the manufacture of specification TC-8WM cylinders without having to perform the macro-etch test. The next edition (i.e. the edition following the 2008 edition) of CSA Standard B339, which will soon be published and available for adoption in the Transportation of Dangerous Goods Regulations, will allow this practice. The certificate holder has demonstrated that when transported under the conditions stipulated herein, the cylinders could be transported with an equivalent level of safety.

Under Canadian Law, a foreign manufacturer of non-specification cylinders cannot be charged with an offence under the Transportation of Dangerous Goods Act, 1992 for failure to comply with the conditions of an Equivalency Certificate. However, certain remedies under the Act are available to Transport Canada in this eventuality.

These include:

1. detention of dangerous goods and consequently the means of containment containing them (subsection 17(1));

2. detention of the means of containment whether full or empty (subsection 17(1));

3. directions not to import the means of containment or to return them to origin (subsection 17(3));

4. inspectors' directions (section 19);

5. directions to importers of the means of containment to issue notices of defective construction or recall (subsection 9(2)); and

6. revocation of the certificate, thereby making any use of the means of containment an offence (subsection 31(6)).

If none of the foregoing are adequate, Protective Directions may be issued to prohibit or to control the use of the means of containment (section 32).
