Hot water system installation involves the removal and replacement or new installation of electric, gas, solar and heat pump hot water systems. While not always high-risk construction work, the activity involves electrical isolation, gas connections, working at heights (roof-mounted solar), manual handling of heavy units, and scalding risks from pressurised hot water. A SWMS ensures each of these hazards is systematically controlled.
While this specific activity may not always constitute high-risk construction work under Schedule 1 of the WHS Regulation 2025, the PCBU's primary duty of care under Section 19 of the WHS Act 2011 (NSW) requires the systematic identification and control of workplace hazards. Preparing a SWMS for this activity demonstrates proactive compliance with that duty and provides auditable evidence of the risk management process. Many Principal Contractors require a SWMS for all construction activities regardless of HRCW status — this document meets that commercial requirement while also ensuring regulatory compliance. It is authored by a Certified Industrial Hygienist (CIH, MAIOH) against the current regulatory baseline, including the WHS Act 2011 and the WHS Regulation 2025.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Electrical isolation and lock-out/tag-out before any electrical work
- 2Depressurise and drain system before disconnection
- 3Tempering valve set to maximum 50°C at outlets per AS 3500.4
- 4Two-person lift or mechanical aid for units over 25 kg
- 5Fall protection system for any roof access (harness, anchor, edge protection)
- 6Asbestos check before disturbing pipe lagging in buildings built before 2003
- 7Gas leak testing with combustible gas detector after reconnection
- 8Customer communication of expected work duration and disruption (psychosocial control)
- 9Scheduled breaks for physically demanding installations (psychosocial control)
- 10All workers must hold a valid White Card (General Construction Induction Training, CPCCWHS1001) before entering any construction workplace in Australia.
- 11Conduct a daily pre-start toolbox talk covering the day's work scope, identified hazards, required PPE, emergency procedures, and any changes since the previous shift. Record attendance and topics in the SWMS consultation section.
- 12PPE baseline for all workers: safety eyewear compliant with AS/NZS 1337.1, Class I or Class II safety footwear with protective toecap per AS/NZS 2210.3, high-visibility clothing where required by site rules, and task-specific RPE, hearing protection, and gloves as identified in the hazard register.
- 13Display the emergency plan at the work area showing first aid kit location, emergency contacts (000, site emergency number, nearest hospital with address), evacuation routes, and assembly point. Review with all workers at pre-start.
- 14Consult workers on WHS matters affecting them per Section 47 of the WHS Act 2011 (NSW). Record the consultation — who was consulted, what issues were raised, what was decided — in the SWMS consultation section. If an HSR has been elected, obtain their acknowledgement.
- 15Review and update this SWMS whenever the work scope changes, after any incident or near miss, when a worker or HSR raises a WHS concern, when new hazards are identified, or at minimum every 12 months. Document the review in the revision log.
- 16Ensure all plant and equipment used has been inspected, maintained, and is fit for purpose. Conduct pre-use checks on power tools, plant, and safety equipment. Remove defective equipment from service immediately and tag out of service.

Worked example
A four-person crew is subcontracted to perform hot water system installation at a warehouse-to-office conversion in Penrith, 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 — electrical contact, scalding, manual handling are confirmed as relevant. Although not classified as HRCW for this specific scope, the Principal Contractor requires a SWMS for all subcontractor activities as part of their WHS Management Plan. 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 Hot Water System Installation SWMS cover?
This SWMS identifies and assesses 8 hazards specific to hot water system installation, including electrical contact, scalding, manual handling, and gas leak. 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.
Is this SWMS compliant with the Section 26A changes commencing 1 July 2026?
Yes. From 1 July 2026, 34 approved Codes of Practice become legally binding under Section 26A of the WHS Act (NSW). A PCBU must either comply with each applicable Code or demonstrate an equivalent or higher standard. This SWMS already cites the relevant Codes that will become binding — no amendment is required for the July 2026 transition. The applicable Codes are listed in the legislation schedule with their Section 26A status clearly marked.
