Owners, users, agents, manufacturers and contractors of boilers or pressurized equipment are responsible for registering equipment designs with TSSA.
Before pressurized equipment is registered, its design is subject to an engineering review to ensure compliance with the Act, Regulations and adopted safety codes and standards.
To register a design, please refer to the appropriate guideline below:
