Information current: 14 August 2026.
Builders, subcontractors, supervisors and tradies working at a Western Australian public sector workplace should follow current WA work health and safety requirements, as well as the agency's contract and site rules. In practical terms, this means clarifying who controls each part of the job, consulting affected people, assessing the real work area and putting effective controls in place before work starts.
The WA public sector Code supports a systematic approach to safety, including leadership, consultation, planning, training, risk management and review. It uses earlier OSH terminology, so it should be read with the current WA WHS Act, regulations and regulator information.
Main hazards
Public sector workplaces include schools, hospitals, offices, workshops, roads, depots, correctional facilities and remote sites. Many remain occupied while construction, repairs or maintenance are underway.
Common hazards include:
- falls, electrical work, excavations, confined spaces and structural work
- mobile plant, delivery vehicles and pedestrians sharing an area
- asbestos, silica dust, hazardous chemicals and unidentified services
- manual tasks, slips, trips, noise, heat and poorly arranged work areas
- workers operating alone or in remote locations with limited assistance
- violence, aggression, bullying, fatigue and other psychosocial hazards
- disruption to access, security, fire systems or essential services
- staff, patients, students or visitors entering the work zone.
The public sector Code highlights manual handling, slips and falls, working alone, workplace violence, bullying, poor physical environments and inadequate work organisation. Trade-specific hazards need to be assessed alongside these workplace risks.
What to sort out before work starts
Confirm the scope, work area, hours, access restrictions, shutdowns and emergency contacts. Identify the agency representative, principal contractor where applicable, supervisors, subcontractors and workers affected by the activity.
Before mobilisation, agree on:
- who will identify hazards, approve controls and close out actions
- how the agency, contractors, workers and health and safety representatives will consult
- required inductions, competencies, permits and supervision
- isolations, barricades, signage and protection of other workplace users
- emergency, first aid, incident reporting and escalation arrangements
- how changes to scope, sequencing, plant or site conditions will be managed.
An agency induction should be supported by task-specific information. Workers need to understand the actual hazards, controls, exclusion zones, emergency arrangements and stop-work triggers for their job. Relevant training and consultation records should be kept as evidence.
What good controls and documents cover
Apply the hierarchy of control. Eliminate hazards where practicable, then consider substitution, isolation and engineering controls before relying on administrative controls or personal protective equipment. Several controls may be needed where the work interacts with an occupied facility.
The document set depends on the task and contract. It may include a project WHS management plan, risk assessment, safe work procedure, safe work method statement, permits, isolation records, hazardous chemical information, plant checks, emergency arrangements, inspection records, consultation notes and training evidence.
Good documents identify the hazard, selected control, responsible person, required check and evidence. They should reflect the actual work area, plant, public interface and work sequence. Supervisors then need to verify the controls in the field, record corrective actions and review arrangements when conditions change.
When a SWMS or another site-specific document commonly applies
Do not assume that every construction task requires a safe work method statement, or that general agency paperwork answers the question. Before starting, check the current WA regulations and the agency's contract requirements to determine whether the work requires a SWMS. Where one is required, prepare, use and maintain it in accordance with those current requirements.
Even where a SWMS is not required, the work may need another site-specific document. Depending on the activity and agency requirements, this could include a risk assessment, permit, isolation plan, emergency arrangement or task procedure. The document should match the actual task, work area, interfaces and controls, and workers should understand how to apply it.
Practical warning signs
Pause the work and review the arrangements when:
- drawings, service information or hazardous-material records are missing or inconsistent
- a generic document names the wrong task, plant, site or control
- workers have signed paperwork but cannot explain the critical controls
- public access, an isolation or an emergency route is not controlled
- the agency and contractors disagree about responsibility for an action
- weather, occupancy, equipment, scope or sequencing has changed
- an inspection, incident or near miss shows a control is ineffective.
These signs call for consultation, reassessment, corrected controls and a clear record of what changed.
How Blue Safe can help
Blue Safe provides compliant WHS documents tailored to the client's activities, applicable Australian WHS/OHS requirements, jurisdiction and industry. Blue Safe guarantees the document compliance of the WHS documents it provides, including eligible customer documents after Blue Safe has reviewed and upgraded them.
Customers actively put the compliant documents into practice through controls, consultation, training, actions, records and evidence. Blue Safe can help align the document set with WA requirements, public sector interfaces and the way the work will actually be supervised.
Local requirements vary between agencies, contracts and sites. Check current regulator material and the agency's current requirements before starting. A national Model Code may provide general orientation, but it is not automatically applicable law in WA.
