Design & System Components

Highlights include:

• Pipeline design: ensures continuous supply in normal/single-fault states

• Material selection: suited for medical gas purity (e.g., cleanable fittings, non-metallic hose permeability addressed)

• Control & monitoring systems: pressure alarms, shutoff valves, visual/audio alerts

• Final testing: contamination testing and outlet verification before clinical use Government of Prince Edward Island+5Standards Council of Canada+5Accuris Standards Store+5HRAI+5Accuris Standards Store+5NFPA Document Information+5.

Installation, Maintenance & Verification

• Installer qualifications (Clause 11): brazing standards, pipeline purging, installer verification

• Modifications/Repairs (Clause 11.5): requirements for retrofitting or expanding existing systems Accuris Standards Store+1CSA Group+1

• Ongoing maintenance (Clause 15): includes schedules, audit checklists, alarm system testing, pipeline integrity checks nrc-publications.canada.ca+5Accuris Standards Store+5CSA Group+5.

Environmental & Emerging Concerns

• Nitrous oxide emissions: Standard highlights GWP of N₂O (~300× CO₂) and encourages portable cylinder use over central supply to reduce waste NFPA Document Information+1Accuris Standards Store+1.

• Focus on plume evacuation, emergency preparedness, fire safety planning, and environmental controls via added annexes CSA Group.

Training, Accreditation & Compliance

• CSA-authorized training for designers, operators, and technicians ensures qualified personnel CHES.

• Accredited inspection bodies (per SCC) can certify installations to Z7396.1‑22 Standards Council of Canada+15Standards Council of Canada+15CSA Group+15.

Implementation Across Jurisdictions

• Voluntary adoption unless mandated by local health/building codes—organizations must analyze gaps and plan transition Standards Council of Canada.

• Integrated into provincial codes (e.g., PEI) and recognized across Canada for medical gas systems regulation Government of Prince Edward Island.
