How to Fill Out a SWMS

What a SWMS actually is

A Safe Work Method Statement breaks a job into steps, names the hazard in each step, and states the control you'll use to deal with it. That's the whole document. It's required for high-risk construction work, and it has to exist before that work starts — not written up afterwards to close out a job.

The person conducting the business or undertaking — that's you, if you own the trade business — is the one responsible for preparing it, keeping it available on site, and making sure the work is done the way the document says. If the work changes, the SWMS changes with it.

When you need one

The work health and safety regulations define a list of high-risk construction work, and if your job includes any of it, a SWMS is required. The current list sits with Safe Work Australia and with your state or territory regulator — check it rather than working from memory, because the categories are broader than most tradies expect. Work commonly caught by it includes:

• Work with a risk of falling more than a set height. The trigger height is in the regulations and it is lower than most people assume — measure it, don't eyeball it.
• Work on or near energised electrical installations or services.
• Work that disturbs or is likely to disturb asbestos.
• Work in or near a confined space, a trench past a set depth, or a tunnel.
• Demolition of anything load-bearing, and structural alterations needing temporary support.
• Work on or near pressurised gas mains, chemical, fuel or refrigerant lines.
• Work on or adjacent to a road, railway or traffic corridor still in use.
• Work in an area with moving powered mobile plant.
• Tilt-up or precast concrete work.
• Work in or near water deep enough to drown in, and diving work.

Outside those categories a SWMS isn't mandatory, but plenty of head contractors ask for one anyway as a condition of getting on site. If you're subcontracting to builders, expect to produce one whether the regulations demand it or not.

What goes in each section

Whatever layout you use, the document has to carry the same information. Work through it in this order:

1. The job and the site. Your business name and ABN, the client, the site address, the principal contractor if there is one, the date, and a document or serial number so you can find it again. Name the specific job, not the trade.
2. The people. Who's doing the work, what tickets they hold, and any subcontractors on site with their contact details. If a licence or a high-risk work licence is needed for a step, say which one.
3. The work steps. Break the job into the actual sequence — set up, isolate, access, do the work, test, pack down. Keep each step small enough that a single hazard attaches to it. Vague steps hide the risk.
4. The hazards. For each step, what could hurt someone. Be specific: not "electrical", but "live 240V supply to the switchboard while the meter panel is open".
5. The risk rating. Rate each hazard by how likely it is and how bad the outcome would be. Most matrices run from very low to critical. Rate it before controls, then again after.
6. The controls. How you'll deal with each hazard, working down the hierarchy of controls. This is the part the document exists for.
7. Sign-off. Everyone doing the work signs to say they've read it and understood it. Unsigned, it's a filing exercise.

Using the hierarchy of controls properly

The controls column is where most SWMS go thin. The hierarchy exists because the options are not equally effective, and you're expected to work from the top down rather than jump to the bottom:

• Eliminate — don't do the hazardous thing at all. Prefabricate at ground level instead of cutting at height. Most effective, and most often skipped over.
• Substitute — swap it for something safer. A different product, a different method.
• Isolate — separate people from the hazard. Barriers, exclusion zones, locking off and tagging out.
• Engineering controls — change the plant or the setup. Edge protection, guarding, mechanical lifting, extraction.
• Administrative controls — change how people work. Sequencing, permits, training, signage, rotation.
• PPE — last, and never on its own. If your control column says "gloves and safety glasses" and nothing else, you haven't done the assessment.

Re-rate the risk once the controls are in. If anything is still sitting at high or critical, the controls aren't enough — go back up the hierarchy rather than accepting the rating and signing it off.

Keeping it alive on site

A SWMS has to be available at the workplace while the work is being done, and it has to match what's actually happening. Three things keep it honest:

• Walk the crew through it before work starts. Reading it out at the tailgate takes five minutes and is the only way you know it's been understood rather than just signed.
• Review it when the job changes. New trade on site, weather turns, a hazard you didn't see when you wrote it — amend the document and re-sign it.
• Keep it after the job. If there's an incident, the regulator will want the SWMS that was in force at the time. Retention periods differ by jurisdiction, so check yours and keep it at least that long.

What gets a SWMS rejected

• It's generic. Downloaded, business name changed, nothing about this site.
• The steps are too big. "Install switchboard" is a job, not a step.
• Controls are all PPE. No elimination, no isolation, no engineering.
• Nobody signed it, or the signatures are from people who aren't on site today.
• It was written after the work started, which defeats the point of the exercise entirely.
• It doesn't get updated when the scope changes, so by week two it describes a job that no longer exists.
