What does AS 4024 actually require? A practical breakdown for machine owners

You know AS 4024 exists. You know it has something to do with machinery safety. But when someone asks what it actually requires of you as the person who owns, operates or manages machines on site, the answer gets murky fast.

That's a problem. Because when an inspector walks onto your site, "we weren't sure what was required" doesn't stop the notice from being issued.

Here's what AS 4024 actually asks of machine owners, in plain language.

First, what is AS 4024?

AS 4024 is Australia's primary series of standards for the safety of machinery. It's not one document. It's a collection of parts covering everything from risk assessment principles and guarding requirements to emergency stops and safe distances.

The parts that matter most to machine owners and operators fall broadly into three areas:

• Risk assessment: identifying hazards and determining what level of risk each machine presents.

• Risk reduction: applying the right controls (guarding, interlocks, safe distances, emergency stops) to bring that risk down.

• Documentation: proving you've done the above in a way that's repeatable, consistent and auditable. If you're a manufacturer, AS 4024 shapes how you design and build machines. But if you're an owner or operator, it shapes how you assess, manage and maintain them once they're on your site.
  
  

The bit most people get wrong

There's a common assumption that once a machine arrives on site with a manufacturer's compliance certificate, you're covered. You're not.

AS 4024 places obligations on machine owners too. If you modify a machine, change how it's used, move it to a different environment or simply continue operating it as it ages, the risk profile shifts. And the responsibility to reassess sits with you.

That means:

• A machine that was compliant when it left the factory may not be compliant in the way you're using it today.

• A risk assessment done three years ago may not reflect the current state of the machine or the tasks being performed on it.

• A guarding solution that met the standard for one application may not meet it for another.
  

This is where most compliance gaps live. Not in deliberate negligence, but in the assumption that compliance is a one-time event rather than an ongoing obligation.

What AS 4024 expects you to have in place

Strip away the technical language and AS 4024 is asking machine owners to demonstrate four things:

You've identified what can hurt someone

Every machine on your site needs a hazard identification process. Not a gut feel. Not "we've been running this machine for ten years and nothing's happened." A structured assessment that identifies mechanical hazards (crushing, shearing, entanglement), electrical hazards, thermal hazards, noise and vibration. The full picture.

You've assessed how serious those hazards are

Once you've identified the hazards, AS 4024 expects a risk assessment that considers the severity of potential injury, the frequency of exposure and the possibility of avoiding the hazard. This isn't a tick-the-box exercise. It's a judgement call that needs to be consistent across your fleet, not dependent on whoever happens to be filling in the form that day.

You've applied the right controls in the right order

AS 4024 follows a risk reduction hierarchy. You start with design measures (can the hazard be eliminated or reduced by design?), then move to guarding and protective devices, and finally to information for use. That includes things like signage, training and PPE.

The standard is clear: you don't jump straight to "tell people to be careful." If a guard can reasonably be installed, the expectation is that it is installed. If an interlock can prevent access to a danger zone during operation, the expectation is that it's in place and functioning.

You can prove it

This is the part that catches people out. It's not enough to have done the assessment. You need to be able to show it. That means documented risk assessments, records of what controls were applied and why and evidence that those controls are being maintained and reviewed.

When an auditor or inspector asks to see your machinery compliance records, the answer can't be "it's in someone's head" or "we did it on a spreadsheet somewhere." The expectation is clear, current and retrievable documentation.

"We've got five of the same machine, can't we just copy the assessment?"

This is one of the most common pushbacks we hear. You've got several identical machines from the same manufacturer, same model, same spec. Surely one risk assessment covers the lot?

It's an understandable assumption, but it's a dangerous one.

When you purchase a new machine, the OEM's generic risk assessment is a valid starting point. It reflects the machine as designed and delivered. But the moment that machine goes into operation, its risk profile starts to diverge. Hours of use, operating environment, maintenance history, operator behaviour, modifications and wear and tear. None of these are identical across two machines, even if they rolled off the same production line.

Machine A might have a guard that's been bent and no longer sits flush. Machine B might be operating in a dustier environment that accelerates wear on moving parts. Machine C might have had a part replaced with a non-OEM component. Each of these changes the hazard profile and none of them show up if you've copied a single assessment across the fleet.

Copying a risk assessment across multiple machines doesn't save you time. It exposes you to unidentified hazards on every machine that wasn't individually inspected. And if something goes wrong, "we assessed one and assumed the rest were the same" is not a defence that holds up.

Every individual machine needs to be inspected and assessed on its own merits. That's not red tape. It's the only way to know what's actually happening on your site.

Where it gets difficult in practice

The standard itself is logical. The challenge is applying it consistently across a fleet of machines, across multiple sites, with different people conducting assessments at different times. Especially when every machine needs its own assessment, even when you're running multiples of the same model.

That's where most organisations struggle. Not with understanding what's required, but with doing it the same way every time. When one assessor rates a hazard as moderate and another rates the same hazard as high, you don't have a compliance program. You have a collection of opinions.

Consistency is the hard part. And it's the part that matters most when your records are under scrutiny.

What this means for you

If you're responsible for machinery on site, the practical takeaway is this:

Audit your current state. Do you have documented, current risk assessments for every machine? Are they consistent in methodology, or do they vary depending on who did them and when?

Check your assumptions. Are you relying on manufacturer certificates for machines that have been modified, relocated or are being used differently than originally intended?

Close the documentation gap. If your compliance records live in spreadsheets, filing cabinets or someone's memory, that's your biggest vulnerability. Not because the work hasn't been done, but because you can't prove it has.

AS 4024 isn't asking you to do the impossible. It's asking you to be structured, consistent and able to show your working. The organisations that get this right aren't necessarily spending more time on compliance. They're spending their time more effectively, with systems that remove the guesswork.
