Dangerous substances must be transported in means of containment that comply with UN standards in order to avoid possible discharges. The Regulation refers to various provisions concerning the manufacture, selection and use of means of containment used to transport dangerous substances.

The means of containment must satisfy National Standard of Canada CAN/CGSB 43.150-97 (“Performance Packagings for Transportation of Dangerous Goods”) or National Standard of Canada CAN/CGSB 43.146 (“Design, Manufacture and Use of Intermediate Bulk Containers for the Transportation of Dangerous Goods”).

All standardized means of containment must bear certification safety marks pertaining to their manufacture. To continue to comply with the standards, certain means of containment may be inspected, tested and marked at precise intervals.

A small means of containment has a water capacity of less than 450 litres, e.g. cylinders, jerry cans, pails, barrels or bottles.

Since January 1, 2003, all small means of containment must comply with UN standards.

Large means of containment have a water capacity greater than 450 litres, e.g. tank trucks, large bulk containers, portable tanks or tubes.

Since January 1, 2003, portable tanks with a capacity greater than 450 litres but less than 3 000 litres must be manufactured according to the ONGC-43.146 standard. However, this requirement will only apply starting August 15, 2004 with respect to farm vehicles transporting petroleum products in large means of containment.

Portable tanks manufactured prior to 2003 in accordance with the ULC/ORDC142.13 standard may be used until 2010.

Non-standardized portable tanks with a capacity of between 450 litres and 5 000 litres used to transport diesel fuel¹ may be used until January 1, 2005 in accordance with the Equivalent Level of Safety permit SH 6216 issued by Transport Canada. Even if operators have not expressly applied for this permit, they may take advantage of the rights inherent in the permit. Operators must write permit number “SH 6216” visibly and legibly on the tank in letters at least 25 mm high.

The use of tanks will be authorized beyond January 1, 2005, until 2010, provided that all of the conditions stipulated by Transport Canada are met.

Tank trucks must be built and tested periodically according to the CSA B620 standard. The manufacturer must affix a maker’s name plate.

The intervals between tests vary by type of tank truck. The findings of the tests conducted must be affixed by an establishment recognized by Transport Canada.

The CSA B621 and CSA B622 standards include provisions governing the selection of tank trucks according to the dangerous substances transported.

Only type B double train tank trucks may be used to transport dangerous substances.

As of August 14, 2004, a tank truck transporting dangerous substances must be equipped with a speed recording system capable of recording the date and the time the speed was recorded.
