NZS 7901 – Electricity and gas industries – Safety management systems for public safety

Provides guidance to owners and operators of electricity generation, transmission or distribution network assets, or gas distribution assets, which are required by statute to have a safety management system (SMS) that operates to safeguard members of the public or property of members of the public from safety-related risks arising from the presence or operation of these assets. The standard applies to all electricity transmission and electricity distribution assets in one or more systems with a total capacity equal to or greater than 10 MVA, and to all electricity generation assets in one or more systems with a total capacity equal to or greater than 10 MW. It also applies to all gas distribution assets in one or more systems, including all natural gas and LPG vapour distribution assets, that operate at a pressure equal to or less than 2000 kPa, and supply more than 10 terajoules of gas in any year, or have a flow design capacity equal to or greater than 10 gigajoules per hour. The total capacity for each asset type applies to each energy asset owner or operator irrespective of whether those assets are in one system or separate systems.
