Under BCSA's Boiler and Pressure Vessel Safety Program, we regulate all boilers, pressure vessels, and other pressure equipment to be used in British Columbia. We register the designs of pressure equipment in accordance with the Power Engineers, Boiler, and Refrigeration Safety Regulations. Our Safety Officers inspect pressure equipment during construction and after completion.

Alterations and used boilers

A used boiler or pressure vessel must be registered before it is installed. If an in-service boiler, pressure vessel, or other pressure retaining equipment is to be altered or re-rated, the alteration and the revised design must be registered. For more information on the registration process for alterations or used equipment, please review the Used Boilers and Pressure Vessels  document and the Boilers and Pressure Vessels Repair and Alteration Report Form 1060.
