Gaseous Fuels CAD Consultation (2025)

TSSA invites you to provide feedback on the revised code adoption document (CAD) for Gaseous Fuels. This CAD is adopted by reference in O. Reg 212/01. This CAD adopts the latest edition of CSA B149.1, B149.3, B149.6 and NFPA 160. The consultation will be active for 60 days from November 20, 2025 to January 19, 2026. 

Please note that the proposed revised version of the Gaseous Fuels CAD includes part 1 & 2 of TSSA Field Approval Code, Mobile Food Service Equipment Code, and the TSSA Digester, Landfill and Biogas Code. These codes will no longer be separate code documents when the new Gaseous Fuels CAD is published.
