2. Why should Health & Safety Professionals care?

  • CSA Z462 is referenced in the Canadian Electrical Code,
  • Electrical incidents often occur during routine maintenance or service work at the facility,

    • Financial risk
      • Cost to repair damaged equipment
      • Lost operations due to damaged infrastructure.

  • Check that an Incident Energy Analysis (Arc Flash Study) has been conducted in the last 5 year,
  • Confirm that all maintenance staff have access to the latest 2021 edition of CSA Standard Z462,
