What WHS Regulation 39 Looks Like in Practice for Plant Training and Safe Operating Procedures
A safe operating procedure is useful only when the people doing the work can understand it, apply it and demonstrate the controls in practice.
For plant operators, Regulation 39 turns training from a one-off induction event into an operational system linked to the actual work, the current risks and the controls in place.
What Regulation 39 requires
Under the Work Health and Safety (General) Regulations 2022 (WA), a person conducting a business or undertaking must ensure that information, training and instruction are suitable and adequate for the work being performed.
The content must reflect the nature of the work, the risks present when the training is provided and the control measures that have been implemented. It must also be delivered, so far as is reasonably practicable, in a way the worker can readily understand.
For plant work, this means a generic slideshow or a signature on an induction form is rarely enough by itself. The worker needs information and instruction that match the plant, the task, the site conditions and the decisions they will make during operation, cleaning, maintenance, isolation and response to abnormal conditions.
Start with the work, risks and controls
Before designing training, define the operating context. Identify who uses the plant, what tasks they perform, which energy sources and moving parts are involved, what interfaces exist with pedestrians or other equipment, and which controls must remain effective.
A practical training map links each task to its hazards, required controls, safe operating procedure, supervision level and evidence of competence. This makes it easier to see whether the training genuinely covers the work or merely repeats broad safety messages.
Use the safe operating procedure as a field tool
A safe operating procedure should help a worker make correct decisions at the point of work. It should cover preparation, inspection, start-up, normal operation, shutdown, isolation, cleaning, fault response and escalation.
Keep the language direct and observable. Replace vague instructions such as “operate safely” with clear steps tied to real controls. Use photographs or diagrams where they improve understanding, and make the current procedure available where the plant is used.
Build training as a sequence
A defensible plant-training process normally includes:
site and plant context;
explanation of hazards and controls;
demonstration by a competent person;
supervised practice;
assessment of the worker performing the task; and
authorisation for the level of work the person may undertake.
Knowledge checks can confirm understanding, but they do not replace observation of the task. A licence or external qualification may establish baseline capability, but it does not automatically prove familiarity with a particular item of plant, its attachments or site-specific procedures.
Separate attendance from competence
Attendance records show that a person was present. Competence evidence shows that the person can apply the required controls.
Assessment should use defined criteria and capture what was observed, any limitations, the assessor, the date and the outcome. Where a worker is not yet ready for unsupervised work, the record should state the supervision or restrictions required.
Authorisation should also be role-specific. Someone may be competent for normal operation but not for maintenance, fault clearing, lifting attachments or isolation.
Keep an audit-ready evidence pack
For each plant role, retain the current procedure, training materials, attendance record, assessment criteria, completed assessment, assessor details, authorisation status and any refresher or corrective training.
Good evidence answers four questions quickly:
What was the worker trained to do?
Which risks and controls were covered?
How was understanding and practical application assessed?
What work was the person authorised to perform?
Review training when the system changes
Training should be reviewed when plant, attachments, processes, procedures, site layout or control measures change; when a new hazard is identified; when monitoring shows a control is not working; after an incident or near miss; or when consultation indicates workers cannot apply the procedure.
Refresher training should respond to the reason for the review. Repeating the original module without addressing the changed risk or observed gap may create a new attendance record without improving control effectiveness.
A practical Regulation 39 checklist
Make training specific to the worker’s plant and tasks.
Verify that current risks and controls are covered.
Use language and demonstrations the worker can readily understand.
Include supervised practice and practical assessment.
Record limits, supervision and authorisation.
Keep procedures accessible at the point of work.
Review the system when work or controls change.
Final takeaway
The objective is not to produce more paperwork. It is to create a visible line from risk assessment, to control, to procedure, to training, to demonstrated competence and finally to authorisation.
