Gas fitting work involves the installation, alteration, repair and maintenance of gas piping systems, gas appliances and gas meters. This is high-risk construction work under WHS Regulation 2025 due to work on or near pressurised gas distribution mains or piping. Gas leaks create explosion and asphyxiation risks. All gas fitting work must be performed by a licensed gas fitter, and a SWMS must be prepared before work commences.
This activity constitutes high-risk construction work (HRCW) under Schedule 1 of the WHS Regulation 2025 (NSW). Section 299 of the Regulation requires that a SWMS be prepared before this work commences, be readily accessible at the workplace while the work is being carried out, and be given to the Principal Contractor if one has been appointed for the project. The PCBU directing the work bears a non-delegable duty under Section 19 of the WHS Act 2011 (NSW) to ensure, so far as is reasonably practicable, the health and safety of workers. This SWMS satisfies the documentation component of that duty by systematically identifying hazards, assessing risks, and specifying controls in hierarchy-of-control order. It is authored by a Certified Industrial Hygienist (CIH, MAIOH) against the current regulatory baseline, including the 34 Codes of Practice that become legally binding under Section 26A from 1 July 2026.
Hazards identified
8 hazards covered, sorted by priority.
Fatal — burns, blast injury, structural collapse
Fatal — oxygen displacement This hazard requires specific controls documented in the SWMS hazard register with both inherent and residual risk ratings.

High-Risk Construction Work triggered
Gas Fitting & Gas Pipe Installation involves work that meets the definition of HRCW Category 8 — work on or near pressurised gas distribution mains or piping — under Schedule 1 of the WHS Regulation 2025 (NSW). The specific task elements that trigger this category include on or near pressurised gas distribution mains or piping.
Gas Fitting & Gas Pipe Installation involves work that meets the definition of HRCW Category 10 — work in a contaminated or flammable atmosphere — under Schedule 1 of the WHS Regulation 2025 (NSW). The specific task elements that trigger this category include in an area that may have a flammable atmosphere.
This activity triggers multiple HRCW categories under Schedule 1 of the WHS Regulation 2025. Section 299 of the Regulation imposes the following obligations on the PCBU: the SWMS must be prepared before the high-risk construction work commences; it must be kept readily accessible at the workplace while the work is carried out; it must be reviewed and revised as necessary to ensure it remains current; and it must be given to the Principal Contractor (if appointed) before the work commences. Under Section 300, a PCBU who fails to prepare a SWMS for HRCW, or who allows HRCW to proceed without a current SWMS, commits an offence. The maximum penalty for a body corporate is 50 penalty units ($36,025 in NSW) per offence, and for an individual 25 penalty units ($18,012.50). These are regulatory penalties — they apply in addition to any prosecution under the WHS Act for a Category 1, 2, or 3 offence if an incident occurs. Category 2 offences (failure to comply with a health and safety duty that exposes a person to a risk of death or serious injury) carry a maximum penalty of $1,500,000 for a body corporate and $300,000 and/or 5 years imprisonment for an individual. From 1 July 2026, Section 26A of the WHS Act further requires that PCBUs comply with all applicable Codes of Practice — this SWMS already cites the relevant Codes.

Worked example
A three-person team is subcontracted to perform gas fitting & gas pipe installation at a 3-storey commercial office building in Blacktown, western Sydney. The project is managed by a Principal Contractor under a $2.1 million head contract. Before mobilising to site, the licensed plumber downloads this SWMS and customises it: entering the PCBU name and ABN, the site address, and the Principal Contractor details on the title page. The 8 hazards are reviewed against the specific site conditions — gas leak, gas leak, burns from brazing or soldering gas pipe are confirmed as relevant. The work triggers HRCW Category 8 under Schedule 1 of the WHS Regulation 2025, requiring this SWMS to be prepared before work commences and provided to the Principal Contractor. At the Monday pre-start meeting, the licensed plumber briefs the crew on the SWMS content, walks through the hazard register, confirms PPE requirements, and has all workers sign the sign-on register. The signed SWMS is stored in the site shed and a digital copy emailed to the PC's document controller. On Wednesday, an unexpected underground service is discovered — the SWMS is amended to add the new hazard, the crew is re-briefed, and all workers re-sign the updated version. The revision is logged in the revision history.

Frequently asked questions
What specific hazards does this Gas Fitting & Gas Pipe Installation SWMS cover?
This SWMS identifies and assesses 8 hazards specific to gas fitting & gas pipe installation, including gas leak, gas leak, burns from brazing or soldering gas pipe, and fume inhalation. Each hazard is documented with a realistic worst-case consequence, an inherent risk rating using a 5x5 likelihood-consequence matrix, specific control measures ordered by the hierarchy of controls, and a residual risk rating after controls are applied. The controls reference the applicable WHS Regulation section, Code of Practice, or Australian Standard so you can demonstrate regulatory compliance.
Is this SWMS written for WHS Regulation 2025 or 2017?
This SWMS is written against WHS Regulation 2025 (NSW) — the current regulation that commenced on 22 August 2025 and replaced the superseded WHS Regulation 2025. All regulation references (r.298, r.299, r.300, Schedule 1) cite the 2025 Regulation. Many competitor SWMS templates still reference the 2017 Regulation — those templates are referencing repealed legislation and should not be used without updating the regulatory citations.
Can I use this SWMS in states other than NSW?
Yes, with amendments. The SWMS includes a state-variance reference table covering all Australian jurisdictions. For Queensland, South Australia, Tasmania, NT, ACT, and Western Australia, the core WHS framework is similar (model WHS Act) and the amendments are minor — primarily regulator contact details and penalty unit values. Victoria requires more significant amendment because it operates under the OHS Act 2004 and OHS Regulations 2017, uses different terminology (Compliance Codes rather than Codes of Practice), and does not have Section 26A. The state-variance table identifies the key differences for each jurisdiction.
How do I customise this SWMS for my specific project?
Open the DOCX in Microsoft Word and complete the title page fields — PCBU name, ABN, site address, project name, and Principal Contractor details. Review the 8 hazards against your actual site conditions: confirm which hazards apply, add any site-specific hazards not already listed (e.g. proximity to a school, heritage constraints, contaminated ground), and adjust control measures to reflect your available equipment, crew competencies, and site access arrangements. Replace the emergency contacts with the actual site emergency number, nearest hospital, and your first aid officer. Add your company logo to the document header. Have the PCBU sign the approval block, brief all workers on the content, and collect sign-on register signatures before work commences.
Which HRCW categories does gas fitting & gas pipe installation trigger under Schedule 1?
This activity triggers Category 8 — Work on or near pressurised gas distribution mains or piping; and Category 10 — Work in a contaminated or flammable atmosphere. Because the work is HRCW, a SWMS must be prepared before work commences (r.299), kept available on site (r.300), and provided to the Principal Contractor if requested. The SWMS documents each triggered HRCW category and the specific task elements that meet the Schedule 1 definition, so you can demonstrate to SafeWork NSW inspectors exactly why a SWMS was prepared and how the hazards are controlled.
Do I still need a separate gas-fitting licence?
Yes. This SWMS documents the hazards and controls for gas-fitting work but does not replace the requirement for a licensed gas fitter to perform and certify the work. Gas fitting is regulated under state-specific legislation (e.g. Gas and Electricity Consumer Safety Act 2017 in NSW). The SWMS references the pressure-testing requirements of AS/NZS 5601.
