One: the generic document
A SWMS downloaded or inherited, with the company name changed and nothing else. It will name hazards that are not present and miss the ones that are. The giveaway is usually a control referring to plant, materials or conditions that do not exist on the job.
Two: high-risk work buried inside a general step
Working at height appears as a line inside "install cladding" rather than as its own step with its own controls. The risk is not that the hazard was unknown — it is that nobody had to think about the control, because the control was never written separately.
Three: controls that are entirely administrative
"Workers to be careful", "ensure area is clear", "follow safe work practices". These are instructions to be safe, not controls. They cannot be implemented, verified or audited, and they place the whole weight of the risk on an individual making the right decision under pressure.
Four: nobody on the crew has read it
The document is correct, current and filed. The crew signed the front page at induction and have not opened it since. This is the most common failure of all, and it is a communication failure rather than a documentation one — which is why rewriting the SWMS does not fix it.
Five: uncontrolled revisions
- Several versions of the same SWMS in circulation with no way to tell which is current.
- No revision number, or a revision number that never changes even though the content has.
- The site copy and the office copy differ.
- A superseded version still in the crib hut or still on a subcontractor phone.
Six: the SWMS does not match the permit or the ITP
The SWMS says one method, the permit to work authorises another, and the inspection and test plan expects a third. Each document is defensible alone. Together they show nobody reconciled them.
Why these persist
Because none of them stop the job. Every one of these failures can sit on a site for months without consequence, which is precisely why they are still there when something does go wrong.
Common questions
What is the most common SWMS problem?
A generic document that does not describe the site it is being used on. It is also the easiest to spot and the easiest to fix.
Is a signed SWMS enough to show compliance?
A signature shows a document was presented. It does not show the work was done that way, which is why evidence of supervision and verification matters alongside the document.
