Identify CSA Z7396.1 as Canada's counterpart standard to NFPA 99 for medical gas pipeline systems

Steps

1. Confirm CSA Z7396.1 (Medical gas pipeline systems — Part 1: Pipelines for medical gases, medical vacuum, medical support gases, and anaesthetic gas scavenging systems) is Canada's counterpart standard, with the current edition being Z7396.1:22 (5th edition), superseding 2017/2012/2009/2006 editions
2. Confirm Z7396.1 is comparable in scope to ISO 7396-1 and ISO 7396-2 but is adapted to reflect Canadian practices and requirements
3. Confirm Z7396.1 addresses design, material/component selection and cleanliness, installation procedures, and system configuration, and that Clause 11.5 specifically addresses repairs, additions, and modifications to existing pipeline systems (new installations are the primary focus; existing systems are not required to be retrofitted)
4. Confirm personnel qualification for installation is addressed by requiring compliance with a recognized Canadian medical gas piping personnel certification program (e.g., a CSA-recognized program) or equivalent — verify the current specific program name/reference directly on the CSA Group or Standards Council of Canada site rather than assuming a separate 'Z7396.2' personnel standard exists, since this could not be confirmed as a current, separate active standard
5. Confirm which edition of Z7396.1 is adopted by the relevant Canadian province/territory before citing clause numbers, similar to NFPA 99 edition adoption lag in the U.S.
