Responding to a SafeWork Site Visit on a Residential Build
How a residential builder should respond when a WHS regulator inspector attends a site, including PIN response, improvement and prohibition notices and what inspectors check.
What it is
A SafeWork site visit is a WHS regulator inspection carried out under the model Work Health and Safety Act, which is in force across Australia except Victoria where the Occupational Health and Safety Act 2004 (Vic) applies. The regulator goes by different names in each state. SafeWork NSW, WorkSafe Victoria, Workplace Health and Safety Queensland, WorkSafe WA, SafeWork SA, WorkSafe Tasmania, WorkSafe ACT and NT WorkSafe all run construction inspection programs.
Inspectors visit residential sites for three reasons. A complaint, a notifiable incident or a planned construction campaign such as falls from heights, silica or electrical safety. The model WHS laws give inspectors broad entry, inspection and notice powers, and the response on the day shapes whether the visit closes as a verbal direction or escalates to a notice on the public register.
When SafeWork attends
The triggers are predictable. A worker complaint, a notifiable incident reported by the builder under the WHS Act, a planned construction campaign or a follow up to a previous notice. Inspectors do not need to give notice before attending.
Powers of a WHS inspector
Inspectors can enter a workplace at any reasonable time without a warrant, inquire of any person at the workplace, require records to be produced, take photographs and measurements, take samples, seize evidence under warrant in serious cases and direct that work cease where there is an immediate risk to safety.
Notices inspectors can issue
The model laws contain three notice types that matter on a residential site.
An improvement notice directs the person conducting a business or undertaking (PCBU) to remedy a contravention or likely contravention within a specified period. A prohibition notice stops an activity that involves or will involve a serious risk to the health and safety of a person. A non-disturbance notice preserves the site of a notifiable incident for investigation.
Provisional Improvement Notices
A Health and Safety Representative (HSR) can issue a Provisional Improvement Notice (PIN) directly to the PCBU. The HSR must first consult the person responsible for the issue and the PIN must allow at least eight days for compliance. A copy of any PIN must be provided to the WHS regulator as soon as practicable, regardless of whether it will be challenged.
What inspectors look for
The construction campaign focus areas drive what gets photographed.
High-risk construction work documents
Safe Work Method Statements (SWMS) for each high-risk construction work activity on site, signed by the workers carrying out the work. A SWMS is required under the model WHS Regulations for the 18 high-risk construction work categories including work at heights above 2 metres, structural alterations, work near live electrical and trenching deeper than 1.5 metres.
Physical controls
Edge protection on every working level, scaffolding tagged and inspected, void protection on first fix, electrical leads tested and tagged, asbestos identification and a written asbestos register if any pre-1990 material is on site, silica controls including water suppression and respiratory protection for any cutting of engineered stone or masonry.
Site management
The principal contractor WHS management plan for projects above the cost threshold, the site induction register, the licensed asbestos removalist details if friable or non-friable removal is occurring, and the consultation arrangements with HSRs if elected.
Where most builders trip up
The pattern is consistent across every state. SWMS that were prepared once and never updated for the site or the actual sequence of work. SWMS not signed by the workers who are doing the task. Scaffolding tags missing or out of date. Edge protection partly stripped to suit a delivery without a written change of method. Subcontractors who turn up without their own SWMS and rely on the head builder document. No consultation with workers or HSRs before changing a control.
On site, the trip up is interview discipline. A casual comment to an inspector about how a control was changed yesterday can become the basis for a notice today.
Immediate response actions
The first hour matters most.
On the day
Cooperate. Confirm the inspector identity and the section of the Act being relied on. Walk the site with the inspector and the site supervisor together. Produce the SWMS, principal contractor WHS management plan if required, induction register and licence records. Take parallel photos. If an interview is requested, the worker can have a support person present. Do not speculate about causes or admit fault.
Within 24 hours
Document what was inspected, what was discussed and what was requested in writing. If a notice was issued, read it carefully. Notices specify a date for compliance and the consequences of non-compliance, which can include on-the-spot fines and prosecution.
If an improvement notice is issued
Comply within the specified time or lodge an internal review request within 14 days under the model WHS Act. Internal review goes to a senior officer at the regulator. Further review can be sought from the relevant tribunal.
If a prohibition notice is issued
Work covered by the notice must stop immediately. The prohibition stays in force until the inspector or the regulator confirms compliance. Trying to keep working around a prohibition notice exposes the builder, the directors and any officer to personal liability under the WHS Act.
If a PIN is issued by an HSR
The PIN must be provided to the regulator. The PCBU can request a review by an inspector within seven days of being issued the notice. If no review is requested, the PIN must be complied with by the date stated, which is at least eight days from issue.
TradeLens framing
The WHS files that turn into notices are usually the ones with the worst document discipline, not the worst site practice. TradeLens maps SWMS coverage, scaffold inspection currency, asbestos identification and high-risk construction work flags against the regulator published campaign focus areas and surfaces the sites most likely to attract an inspection or fail one.
