Plumbing SWMS template: safe work method statement for plumbers

A lot of plumbing is not high-risk construction work. Replacing a rooftop solar hot-water cylinder is: fall greater than 2 m, a heavy vessel, and often electrical or gas isolation. Be honest about the job in front of you — don’t buy a SWMS for a tap washer, and don’t take a JSA onto the roof.

When plumbing is HRCW — and when a JSA is enough

Under the model WHS Regulations (reg 291), these high risk construction work triggers commonly apply to plumbing:

A risk of a person falling more than 2 m — roofs, hot water systems and gutters.
Work in or near a trench or shaft deeper than 1.5 m — sewer and stormwater connections.
Work in or near a confined space — pits, tanks and manholes.
Work on or near pressurised gas distribution mains or piping.
Work on or near chemical, fuel or refrigerant lines.
Work on or near energised electrical installations or services.
Work likely to involve disturbing asbestos.
Work in an area with movement of powered mobile plant, such as excavators.
Work adjacent to a road or other traffic corridor in use by traffic.

Victoria uses its own OHS Regulations 2017, with a similar list.

This page is for plumbing that hits an HRCW category. Rooftop storage, work near a live booster or gas, trenches for sewer — SWMS. Ground-floor isolated fit-off of a mixer with the water off and no live services in the wall: a JSA is the honest document.

If the electrical isolation is the hard part of the job, the sparkie may need the electrical SWMS as well. Don’t hide live electrical work inside a plumbing JSA.

Generic plumbing SWMS vs job-specific

A generic plumbing SWMS is a useful starting point. But the SWMS used on site must reflect the actual high risk work, hazards and controls at that site, and it must be reviewed and revised if the work or conditions change.

Start from a generic plumbing template, then add:

The site address.
The specific HRCW tasks on this job.
The people responsible for each step.
Site controls, such as trench shoring or benching, gas isolation and permits.

The principal contractor will usually reject a generic, unsigned SWMS. Check the what a SWMS must include guide, then generate a plumbing SWMS for the job in front of you.

Common plumbing hazards and controls

Not sure whether a task is HRCW? Use the high risk construction work checklist.

Trenching and excavation

Shore, bench or batter the trench. Keep spoil at least 1 m back from the edge, and check for underground services with Before You Dig Australia before you dig.

Gas work

Isolate the supply, purge and leak test, keep the area ventilated, and have the gas work done by a licensed gasfitter.

Hot work and brazing

Keep a fire extinguisher at hand, clear combustibles from the area, and get a hot work permit where the site requires one.

Confined spaces

Confined space entry needs its own entry permit under the WHS Regulations. Test the atmosphere before and during entry, and keep a standby person outside.

Sewage and biological hazards

Wear gloves, wash before eating or smoking, and ask your GP for advice on hepatitis A and B vaccination.

Asbestos

Old fibre cement pipes, flues and wall sheeting may contain asbestos. Stop and test before you cut or drill, and use licensed removal where required.

Silica dust

Cutting or core drilling concrete and masonry creates silica dust. Use on-tool water suppression or extraction, and wear RPE.

Manual handling

Pipe lengths and HWS units are heavy and awkward. Use mechanical aids and two-person lifts.

Filled example: rooftop solar HWS, Fremantle WA

Two-storey limestone house. Replace the failed solar storage cylinder on the roof, crane from the street, reconnect the booster. Occupied dwelling. Not a ground-floor tap, not a new-house rough-in.

Job / task: Replace rooftop solar hot-water storage cylinder
Site: Two-storey dwelling, Fremantle WA 6160
Document: SWMS · HRCW: fall > 2 m · example only
PPE: Hard hat, hi-vis, steel-caps, glasses, gloves, sun protection, harness with edge protection

Example layout. Residual risk on a live roof often stays High. Ground-floor isolated mixer fit-off is not this job — use a JSA. Energised booster circuit: electrical SWMS.

Step	Hazards	Controls	5×5 risk
1. Isolate water, booster power and any gas; set roof access and the street crane zone Responsible: Licensed plumber	Booster still live Fall more than 2 m getting onto the roof Public under the crane on a Fremantle one-way street	Isolate and prove the booster; if you cannot prove dead, stop and get a sparkie — that is electrical HRCW, not a plumbing shortcut Edge protection or a documented rope system before anyone works the pitch Traffic plan / spotter; no lifts over people	InitialL3×C5 = 15 High ResidualL2×C5 = 10 High
2. Drain and disconnect the old cylinder Responsible: Plumber	Hot water / residual pressure Manual handling of a waterlogged cylinder on a pitch Slip on wet tiles	Drain from the valve; don’t crack unions against pressure Wait until it is empty enough to lift; two-person; never roll it to the eave Crawl boards; keep the exclusion live below	InitialL4×C5 = 20 Critical ResidualL2×C5 = 10 High
3. Move the new cylinder from the truck to the crane pick point and rig it Responsible: Leading hand / dogman	Manual handling of the cylinder at ground level Crushed hands or feet while rigging	Trolley or two-person lift; don’t carry it alone Rig to the manufacturer’s lifting points; gloves and steel-caps; hands clear before the take-up	InitialL3×C4 = 12 High ResidualL2×C3 = 6 Medium
4. Crane the new cylinder onto the roof and strap it Responsible: Leading hand / dogman	Load swing — struck-by or pulling a worker off the roof Cylinder rolling toward the eave before it is strapped Wind on the lift	Tag lines; no one under the load; stop the lift in wind Land onto prepared blocks; strap before the hook comes off Radio between roof and street	InitialL3×C5 = 15 High ResidualL2×C5 = 10 High
5. Connect the new cylinder to the water supply and booster gas line Responsible: Licensed plumber / gasfitter	Water or gas supply turned back on before connections are made Gas leak at the booster connection	Keep the water and gas isolated and tagged until every connection is made Gas connection by a licensed gasfitter; leak test before the booster is lit	InitialL3×C5 = 15 High ResidualL1×C5 = 5 Medium
6. Reconnect, fill, commission, pack up the roof Responsible: Licensed plumber	Leak onto electrics at the booster Fall during pack-up when people get casual Tools left on the pitch	Fill slowly; check unions before the booster is livened Edge protection stays until the last person is down Count tools; owner walk-through from the ground	InitialL3×C5 = 15 High ResidualL2×C5 = 10 High

Frequently asked questions

Do plumbers always need a SWMS template?

No. You need a SWMS when an HRCW category applies — fall greater than 2 m, work near energised electrical, near pressurised gas mains, asbestos, a trench, and the rest of the high-risk construction work categories. A ground-floor isolated mixer swap often only needs a JSA.

Is the plumbing SWMS free to download?

Creating an account is free and needs no card; creating and editing your own site-specific draft is free too. The $20/month subscription is only needed to download the PDF. The Fremantle rooftop HWS example is a layout, not a lift plan for a different cylinder.

SWMS or JSA for plumbing?

Roof, live electrical, gas mains, deep excavation: SWMS. Ground-floor isolated fit-off with no other HRCW: JSA. If you are unsure, read the SWMS vs JSA guide and the high-risk construction work checklist.

Does this work in NSW, VIC, QLD and WA?

State-aware citations (WHS, or Victoria’s OHS Act 2004 and OHS Regulations 2017). Plumbing licences and gas / electrical rules in each state still apply.

Can I use a generic plumbing SWMS?

As a starting point, yes. The SWMS you use on site must reflect the actual high risk work, hazards and controls at that site, and it must be reviewed and revised if the work or conditions change. Add the site address, the specific HRCW tasks, the people responsible and the site controls. A principal contractor will usually reject a generic, unsigned SWMS.

Does a plumber need a SWMS for every job?

No. A SWMS is required only for high risk construction work. Lower-risk jobs, such as an isolated ground-floor fit-off, can use a JSA or another risk assessment.

Check the official guidance

A SWMS sets out the high-risk construction activities, their hazards and the controls to use. Prepare it before the work starts, adapt it to the site and review it when the work or controls change. Consult the people doing the work. An AI draft or example needs review before use.

Model WHS guidance and Victorian requirements differ. Check the rules that apply to your workplace.
