Job Hazard Analysis · applied planning and control
Workers, supervisors and HSE personnel who prepare, review or use task-specific JHAs
What learners will practise.
- Define the task boundary and identify information required before release.
- Develop a meaningful job sequence with the people who perform the work.
- Describe credible hazard–event–harm chains and affected people.
- Select prioritised controls with owners, verification and stop triggers.
- Brief a team, respond to change and produce a defensible practice JHA.

Start with understanding.
A signed form is not evidence that the work is controlled.
Then make a decision.
A crew will replace filters on a roof. The copied JHA covers a ground-floor unit. The roof access route is wet and a delivery is scheduled below the work. The supervisor says the task takes only ten minutes. Decide what must change before work begins.
Discuss: What are the facts, what could go wrong, and what must be verified before proceeding?
Make it specific to your workplace.
- Approved risk criteria and acceptance authority
- Task method, equipment and people affected
- Stop-work and change-control procedure
Before deployment, confirm these details with the client’s responsible technical reviewer. The course is a starting point for awareness learning, not a replacement for approved work procedures.
