Start with the work, not the document
A SWMS is only meaningful next to the job it describes. Before you open the document, find out what is actually happening: which trade, which part of the structure, what plant is on site, who else is working above and below, and what the sequence is that week.
If you review a SWMS without that, you are proofreading. You will catch spelling and formatting and miss the thing that hurts someone.
The six checks that find real problems
- Do the steps match the sequence? Read the job steps in order and ask whether that is how the crew will actually do it. Steps written in the wrong order usually mean the document was copied from another job.
- Is every high-risk element named? If the work involves a fall risk, a trench, energised services, confined space, demolition, asbestos, mobile plant or structural alteration, each one should appear as its own step with its own controls — not folded into a general line about working safely.
- Do the controls sit at the right level? A control that depends entirely on a worker remembering something is the weakest kind. Look for elimination, substitution, isolation and engineering before you accept administrative controls and PPE.
- Is it this site? Named access points, named plant, named adjacent trades, the real ground conditions. A SWMS that would read identically on any site in the country has not been written for yours.
- Can the crew do what it says? If the controls require a spotter, is there a spotter? If they require an exclusion zone, is there room for one? A control that cannot physically be implemented is worse than no control, because it creates a false record.
- Is it current? Check the revision, the date and whether anything on site has changed since — a new level, a new subcontractor, different plant, a change in weather exposure.
What a good review produces
A review is not a yes or a no. It is a short list of specific changes with the reason attached, so the person who wrote the SWMS can fix it rather than guess.
Record what you sighted, when, and against which revision. If the SWMS is later used as evidence, the review needs to be traceable to a version — "we reviewed it" is not a record.
The mistake almost everyone makes
Reviewing against a checklist of headings rather than against the work. A SWMS can contain every required heading, be internally consistent, and still describe a job nobody is doing. Headings are the easy half.
Common questions
Who should review a SWMS?
Someone who understands the work and is independent enough of it to say no. In practice that is often the principal contractor or a site supervisor, with specialist input where the work is unfamiliar.
How long does a proper SWMS review take?
For a familiar trade on a known site, around twenty to forty minutes per document if you are checking it against the actual work. Much faster than that usually means the work was not examined.
Does a SWMS need to be reviewed again if the work changes?
Yes. A change in method, sequence, plant, crew or site conditions is the point at which the document stops matching the job, which is exactly when it stops being useful.
