Three documents, three different jobs, endlessly mixed up. Here's the 60-second version - and the one-question test at the bottom.
| SWMS | JSA / JHA | SOP | |
|---|---|---|---|
| What it is | Safe Work Method Statement - the LEGAL document for high risk construction work | Job Safety (Hazard) Analysis - a task risk breakdown for any job | Safe Operating Procedure - how to use one machine or do one process safely |
| Legally required? | Yes - before any of the 18 high risk construction work activities starts | No specific law - it's good-practice risk management | Not by name - but it's how you meet training/instruction duties for plant |
| Scope | A specific high-risk TASK on a specific SITE | Any task, any workplace | One machine / process, wherever it's used |
| Lives where | On site, signed by the crew, available to the regulator on request | With the work crew / toolbox | At the machine / in the training pack |
| Typical trigger | Work at heights >2 m, deep excavations, live electrical, demolition, asbestos... | Non-HRCW tasks, or breaking down a new/unusual job | New machine on site, new starter, VOC training |
"Is this task one of the 18 high risk construction work activities?" Yes → you need a SWMS, full stop - a JSA doesn't satisfy the duty. No → a JSA is usually the right tool for the task, and SOPs cover the machines used within it. Many crews run all three: the SWMS for the high-risk work, JSAs for everything else, SOPs on the plant.

This is a practical site-management tool. It is not legal, engineering or regulatory advice and does not guarantee compliance or a satisfactory inspection outcome. Requirements may vary by jurisdiction, project, contract and circumstances.
The tools above are free and yours to use. When you need the paperwork behind them reviewed by someone who has run sites, Obras HSE Services is a live consulting business in south-east Queensland.
