Transport Canada shares a reminder regarding on highway tanks and portable tanks for the definition of a repair according to CSA B620, which includes information related to nurse tank chassis.

Repair: returning a tank to its original design by welding on the tank wall or piping, on protective devices, on structural components, and on any part that contains lading (Clause 3.2, CSA B620:20).

The regulations states that repairs do NOT include:

• changes to vehicle equipment, such as lights, steering and brake systems, and suspensions;
• changes to fender attachments, lighting brackets, and ladder brackets;
• replacement of components, such as valves, vents, or fittings;
• replacement of an attachment by welding to a mounting pad; and
• repairs to a nurse tank chassis.

Repair reports have different requirements than inspection/test reports. The repair report includes information on the repair facility, details about the repair and it identifies the welding procedure that was used. The repair facility must keep a copy for 20 years (Clause 7.5.10, CSA B620:20).

Procedures and welders must be qualified in accordance with ASME BPVC Section IX (Clause 4.4, CSA B620:20).

Finally, Transport Canada reminds everyone that tank testers and inspectors are required to complete training by May 2024. 

Transport Canada has a welding repair quiz you or relevant team members can take to test your knowledge on this type of information.
