    This report summarizes the feedback we received during our online consultation on gas codes. The consultation was held August 10 through September 22, 2021, and covered the impacts of adopting the latest editions of the gas codes in BC and related issues:

    • CSA B149 series (2020 edition)
    • CSA Z662 (2019 edition)
    • BNQ-1784 (2021 edition)
    • Installing carbon monoxide detectors when gas equipment is installed or replaced
    • Draft directive relating to biomethane gas systems
    • Isolating gas systems when performing maintenance


    Process and participation

    Before the gas codes consultation, our gas safety team conducted a technical review of the CSA B149-20 code series and the CSA Z662-19 to identify safety, process, and socioeconomic impacts of the codes. These impacts were further reviewed and refined by two code review advisory groups in 2020, comprised of gas contractors, gasfitters, manufacturers, equipment owners, and other industry experts.

    When it came time to host the consultation, we posted impact assessments on Technical Safety BC’s Engage website, and invited over 20,000 industry representatives to participate. The consultation was promoted through:

    • Direct emails to those registered to receive Technical Safety BC gas-related notifications
    • Direct emails to industry associations
    • Direct emails to advisory group members
    • Social media posts on Facebook, LinkedIn, and Twitter
    • Ads on Facebook and Google
    • Presentations at industry association meetings
    • A gas industry newsletter


    By the end of the consultation period, the consultation webpage had been viewed by over 5,200 unique visitors, and 42 participants had engaged in the consultation surveys, online discussion forums, and email. The participants included:

    • 25 people who identified as gas contractors, gasfitters, utilities, or students/apprentices
    • 6 people who identified as engineers, designers, manufacturers, or suppliers
    • 8 people who identified as industry associations or government representatives
    • 22 people who identified as owners of gas equipment, buildings, or homes
