Dangerous substances must be transported in containers 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 type of container 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 containers must bear certification safety marks pertaining to their manufacture. To continue to comply with the standards, certain containers 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.

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

Large bulk containers (LBC) are containers with a capacity of more than 450 litres and less than 3,000 litres that are manufactured in compliance with standard CNGC-43.146.

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

Note: Large containers for transporting petroleum products on a vehicle used for agricultural purposes must also meet standards.

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.

Transporting dangerous substances in a double tank-truck other than a B-train is prohibited.

All tank-trucks that carry hazardous substances must be equipped with:

• a device for monitoring the driver’s behaviour that records substantial changes in speed and pertinent details, including date, time, and speed;
  OR
• an electronic stability control system that assists the driver in the case of critical handling.

In the case of a highway motor vehicle that is part of a tank truck, and that is assembled prior to August 15, 2006, the equipment described above may be replaced by a speed limiter set to 100 km/h.
