Notifiable Incidents in Construction: What You Must Report, and When

At 10:40 on a Wednesday morning a section of formwork gives way on level two of a Perth apartment build. Nobody is under it. A carpenter twenty metres away is shaken but unhurt, and the site manager’s first instinct is to get the area cleared and the deck made safe before anyone else walks through.

His second instinct, about four seconds later, is the right one. He stops. Nobody was injured, so does this even need reporting? And if it does, is he allowed to move any of it?

What is a notifiable incident?

A notifiable incident is a workplace event that WHS law requires you to report to the regulator immediately. It covers three categories: the death of a person, a serious injury or illness, and a dangerous incident.[1]

The third category is the one that catches people out. A dangerous incident is notifiable even when nobody is hurt at all. If the event exposed a person to a serious risk, the obligation is triggered by the exposure, not by the outcome.

That collapsed formwork is a notifiable dangerous incident. So is an uncontrolled escape of gas, an electrical short circuit or explosion, an implosion, an uncontrolled collapse or partial collapse of a structure, a fall of plant or a load from height, and the uncontrolled escape of a substance under pressure.[2]

When do you have to report it?

Immediately, by the fastest practical means, which is a phone call to the regulator. Written notification follows, generally within 48 hours of the notification being requested.[3]

Immediately means immediately. Not after the toolbox talk, not once you have gathered the facts, not after the head office has been told. The reporting duty sits with the person conducting the business or undertaking, and on a construction project that is usually the principal contractor.

The written notice then has its own retention obligation. A copy of the written notification must be kept for at least five years.[3]

Do you have to preserve the site?

Yes, and this is the obligation most commonly breached in the first ten minutes. The incident site must be preserved until an inspector arrives or the regulator directs otherwise.[4]

There are four permitted reasons to disturb it, and they are narrow. You may disturb the site to protect a person’s health and safety, to aid an injured person, to take essential action to make the site safe, or to prevent a further incident.[4]

Cleaning up is not on that list. Neither is getting the crane back into service, moving the failed component to a shed for a look, or letting a subcontractor recover their gear. Every one of those is a plausible, well-intentioned action that compromises an inspection.

“An incident site may only be disturbed for the purpose of protecting the health and safety of a person, aiding an injured person, taking essential action to make the site safe or to prevent a further incident from occurring.”

What records will the regulator ask for?

The ones you already had. This is the part that separates a manageable inspection from a bad one, and it is decided months before the incident.

An inspector attending a notifiable incident will typically ask for the SWMS for the activity, the risk assessment, the WHS management plan, the induction and sign-in records for everyone on site that day, plant and equipment inspection records, the site diary for the period, and any prior incident or hazard reports covering the same risk.

If a notifiable incident occurs, you must keep a copy of the risk assessment, WHS management plan and SWMS for two years after the incident.[3] Note the direction of that obligation: it assumes those documents existed at the time.

5 years

Minimum retention period for the written incident notification. The SWMS and risk assessment must be kept 2 years from the incident.

WHS Regulations

Why near misses are the expensive ones to ignore

A dangerous incident with no injury feels like a lucky escape, and lucky escapes do not generate paperwork on most sites. That instinct is exactly backwards, for two reasons.

The first is legal. The obligation does not depend on the outcome. Failing to notify a dangerous incident is an offence in its own right, independent of whatever caused it, and it is a much harder one to explain than the original hazard.

The second is evidentiary. If the same failure mode appears later with an injury attached, the regulator will look for what you did after the first one. An unreported near miss with no corrective action is the strongest possible evidence that the risk was known and tolerated. A recorded observation with a closed corrective action is the opposite.

That is why observations and near misses belong in the same register as incidents, captured on site, at the time, by the person who saw it.

What good looks like

The sites that handle a notifiable incident well are not the ones with the best incident procedure. They are the ones where the underlying records already existed and could be produced in an afternoon.

• The SWMS in force for that activity on that day is retrievable by date and version, not reconstructed from an inbox

• Everyone on site that morning is known from the sign-in record, including subcontractors and visitors

• The site diary has the weather, the crews and the activities for the day, written that day

• Plant inspection and maintenance records for the item involved are current and dated

• Prior observations against the same risk are visible, with their corrective actions closed and evidenced

• Photographs are time-stamped and located, so the site condition before the incident is documented rather than argued

None of that is incident management. It is ordinary record keeping, which is the point. The incident is when you find out whether you had it.

The Australian context

WHS law is harmonised across most of Australia, but notification goes to your state or territory regulator, not to Safe Work Australia. Safe Work Australia writes the model laws; SafeWork NSW, WorkSafe Victoria and the others enforce them.[2][5]

Victoria is the notable exception to harmonisation, operating under the Occupational Health and Safety Act 2004 rather than the model WHS Act. The notification categories are broadly similar but the wording and thresholds differ, which matters for builders working across state lines.[5]

For a principal contractor running projects in three states, that means three regulators, three notification lines and three sets of criteria applied to the same event. The practical consequence is that the decision of whether something is notifiable cannot live in one experienced person’s head. It has to be a documented trigger anyone on site can apply at 10:40 on a Wednesday.

This connects to the broader set of duties a principal contractor carries, covered in what HSEQ actually means on a construction site.

Where Plexa fits

Plexa captures incidents and observations on site, on a phone, at the moment they happen, with photographs, location and time stamp attached. A near miss takes the same thirty seconds as an incident, which is what makes it likely to be recorded at all.

Because the same platform holds the sign-in records, the SWMS register, the site diary, plant and equipment records and the inspection history, the evidence package an inspector asks for is a filter rather than a search. Who was on site that morning, which SWMS version was in force, when the formwork was last inspected, and whether anyone had raised this before are all queries against one record.

Corrective actions raised from an observation are tracked to close-out with evidence attached, so the register shows not just what was reported but what was done about it. That is the difference between a register that helps you and one that indicts you.

Back at that Perth apartment build, the site manager makes the call before he touches anything. The area stays taped. When the inspector arrives that afternoon and asks for the formwork SWMS, the inspection records and yesterday’s diary entry, the site manager does not go looking. He filters by date and hands over the lot.

Frequently asked questions

What is a notifiable incident in Australia? A workplace event that must be reported to the WHS regulator immediately. There are three categories: the death of a person, a serious injury or illness, and a dangerous incident that exposed someone to a serious risk.[1]

Do you have to report an incident if nobody was injured? Yes, if it was a dangerous incident. Uncontrolled structural collapse, a fall of plant or a load from height, an electrical explosion, an uncontrolled escape of gas or a substance under pressure are all notifiable regardless of whether anyone was hurt.[2]

How quickly must a notifiable incident be reported? Immediately, by the fastest practical means, which in practice is a phone call to your state or territory regulator. Written notification generally follows within 48 hours of being requested.[3]

Can you clean up or make the site safe after a notifiable incident? The site must be preserved until an inspector arrives or directs otherwise. It may only be disturbed to protect health and safety, aid an injured person, take essential action to make the site safe, or prevent a further incident. General clean-up and returning plant to service are not permitted reasons.[4]

How long do incident records have to be kept? The written notification must be kept for at least five years. If a notifiable incident occurs, the risk assessment, WHS management plan and SWMS relating to it must be kept for at least two years from the date of the incident.[3]

Who do you notify, Safe Work Australia or the state regulator? Your state or territory regulator. Safe Work Australia writes the model laws but does not receive notifications or conduct inspections.
