Should Your Facility Have Automatic Seismic Gas Isolation?

Answer five quick questions to get a straight answer on whether automatic gas isolation is worth investigating for your building. This is a two-minute self-assessment tool, not a professional seismic assessment.

Does your building or site use reticulated natural gas or LPG? Yes, throughout the building or site Yes, but only a small or isolated connection No, or not sure

What best describes how the building is occupied? Continuously occupied (residents, patients, 24/7 staff) Regularly occupied during business hours (staff, students, customers) Rarely occupied (plant room, storage, unmanned site)

Where is the building located? A higher seismic hazard area (e.g. Wellington, Hawke’s Bay, Canterbury, Marlborough, or similar) A lower seismic hazard area (e.g. Auckland, Northland) Not sure

Would a gas fire or forced evacuation seriously disrupt what happens on site? Yes — it’s a hospital, care facility, school, data centre, or otherwise cannot afford disruption Yes — it would be a significant financial or operational loss No — disruption would be manageable

Has an insurer, engineer, or compliance requirement raised gas seismic safety for this building? Yes, specifically Not yet, but we expect it will come up No

This is a guide, not a professional seismic assessment. It’s designed to help you decide whether automatic gas isolation is worth investigating further — it does not replace a %NBS assessment, a CPEng engineer’s structural or seismic evaluation, or formal compliance advice. For a full seismic risk assessment, engage a qualified engineer.
