Quick answer
WHS risk assessment uses a small toolkit applied consistently: a risk matrix to rate likelihood and consequence, the hierarchy of controls to choose the strongest practical control, and job-level tools like JSAs and SWMS, plus checklists and audits to keep it systematic. Cert IV WHS teaches you to use all of these.
The core tools
- Risk matrix — rate each risk by how likely it is and how serious the outcome could be, to prioritise action
- Hierarchy of controls — eliminate first, then substitute, isolate, engineer, administrate, and use PPE last
- Job Safety Analysis (JSA) — break a task into steps and control the hazards in each
- Safe Work Method Statement (SWMS) — required for high-risk construction work; documents hazards and controls
- Checklists and inspections — catch hazards routinely and consistently
- Audits and reviews — confirm controls are working and being followed
How they fit together
Identify hazards, assess risk with the matrix, select controls using the hierarchy, document them (JSA/SWMS), then verify with checklists and audits. The point isn’t paperwork — it’s choosing controls that actually reduce risk.

Frequently asked questions
What’s the difference between a JSA and a SWMS?
Both break work into steps and control hazards. A SWMS is specifically required for high-risk construction work and has set content requirements; a JSA is a more general task analysis.
What is the hierarchy of controls?
A ranked list of control types — elimination, substitution, isolation, engineering, administration, PPE — used strongest-first.
Do I need software for risk assessment?
No. A clear matrix and good process work on paper or in simple tools; software just scales it.
