Set the job boundary
Name the task, site or work area, people involved and the limits of the activity. Note interfaces with other trades, plant, services or public access. If the scope changes, revisit the analysis.

How to write a job safety analysis
A useful JSA is built around the real sequence of work. Start with the crew’s knowledge, identify what could go wrong at each step, and agree on controls that can be put in place and checked.
Break the work into steps
Walk through the task in order, including setup, access, preparation, execution, testing and pack-up. Keep steps observable and manageable. Avoid splitting the work so finely that the sequence becomes hard to use.
Ask what could cause harm
For every step, look at energy sources, falls, moving equipment, manual handling, hazardous substances, environment, weather and nearby work. Involve workers who know the task and site.
Choose controls that fit
Record the specific measures that will be used and how they will be checked. Consider whether the hazard can be eliminated or exposure reduced before relying on instructions or personal protective equipment. Follow applicable requirements and site procedures.
Review with the people doing the work
Have a competent person and the affected workers check whether the steps, hazards and controls match the actual conditions. Resolve gaps, confirm responsibilities and brief the crew before work begins.
Keep it current
Pause and review when the scope, equipment, people, location or conditions change, or when controls are not working as planned. Record updates according to your organisation’s process.
A short example of useful detail
Vague: “Use ladder safely.”
More useful: “Choose access equipment suited to the task and surface; inspect it before use; secure and position it according to site procedure; keep the work area clear; stop and reassess if the ground, weather or access changes.”
The example is illustrative only. It is not a recommended control set for a particular job and should not be copied without assessment.
