Gas Plumbing SWMS Templates

Yes — work on or near pressurised gas distribution mains or piping is listed as High Risk Construction Work under WHS Regulation 2025 Schedule 1 clause 291(l). A SWMS must be prepared before work starts, kept available for inspection, and reviewed if controls change or an incident occurs. This applies regardless of whether the work is also covered by state Gas Safety Act licensing. Medical gas, Type B appliance, and live mains tie-in work typically trigger multiple HRCW clauses simultaneously, including energised plant (291(i)) and confined spaces (291(f)).

The SWMS itself is governed by the model WHS Regulation, which is harmonised across all states except Victoria and WA (which have equivalent but separately enacted laws). However, gas-fitter licensing, certificates of compliance, and notifiable gas work are regulated by state Gas Safety Acts — for example through Energy Safe Victoria, NSW Fair Trading, or the Queensland Petroleum and Gas Inspectorate. A compliant SWMS references both WHS Regulation 2025 and the applicable state gas-fitting requirements for the jurisdiction of work.

A SWMS is a WHS document identifying hazards and controls for the work activity before it begins, required under WHS Regulation 2025 Part 6.4. A gas Certificate of Compliance (sometimes called a Gas Compliance Certificate or COC) is issued by the licensed gas-fitter after the work, certifying the installation meets AS/NZS 5601.1 and is safe to commission. Both documents are required — the SWMS protects workers during the job, while the COC certifies the finished installation to the gas distributor and regulator.

Yes. Medical gas systems are life-safety critical and governed by AS 2896 (installation), AS 2568 (low-pressure flexible hose assemblies), and HTM 02-01 for design. A medical gas SWMS must address oxygen-clean brazing techniques, anti-cross-connection testing, particulate testing, system labelling, and lockout of existing patient-occupied areas. The risk profile is fundamentally different from natural gas — wrong-gas connections can be fatal — so a generic gas-fitting SWMS is not adequate substitute for a medical-gas-specific document.

Under WHS Regulation 2025, the PCBU carrying out the HRCW must prepare the SWMS in consultation with workers doing the work. Each worker must be inducted into the SWMS and sign acknowledgement before starting. The principal contractor must be given a copy before work commences on a construction project. The SWMS must be reviewed if work methods change, controls fail, a notifiable incident occurs, or a health and safety representative requests review under section 70 of the WHS Act.
