If you operate a manufacturing, warehousing, or industrial facility in Australia, machinery guarding is not optional. It is a legal obligation under the Work Health and Safety Act 2011 and associated regulations, and failing to meet that obligation puts your workers, your business, and your licence to operate at serious risk.
The WHS Act requires that persons conducting a business or undertaking (PCBUs) eliminate or minimise risks to health and safety so far as is reasonably practicable. When it comes to moving machinery, automated equipment, robots, and production lines, physical separation is one of the most effective engineering controls available.
The WHS Regulations go further, requiring specific safeguards for plant and machinery that could cause injury through contact, entanglement, or ejection. Guarding is not just best practice. It is a compliance requirement with real consequences for non-compliance.
Safe Work Australia’s guidelines on managing risks of plant in the workplace outline a clear hierarchy of controls. Engineering controls, including physical guarding and barriers, sit above administrative controls and personal protective equipment. If your facility is relying on signage, training, or PPE alone to manage machinery hazards, you are not meeting the standard the law requires.
Beyond the WHS Act and Regulations, compliance with the AS 4024.1 series of Australian Standards is considered best practice and is referenced by regulators and courts when assessing whether a duty holder took all reasonably practicable steps to manage machinery hazards.
The AS 4024.1 series covers the full scope of machinery safety, including guard design and construction, interlocking devices, prevention of unexpected start-up, and the safety-related parts of control systems. Key standards within the series include:
AS/NZS 4024.1601 – Guards: General Requirements
Sets out general requirements for guards, including that they must be robust, correctly positioned, and effective at preventing access to dangerous areas without creating additional hazards. Specifies fixed, movable, and interlocked guard types.
AS/NZS 4024.1602 – Interlocking Devices
Covers interlocking devices that prevent machinery from operating unless guards are correctly in place, and ensure machinery stops automatically if a guard is removed or bypassed.
AS/NZS 4024.1603 – Prevention of Unexpected Start-Up
Addresses the prevention of unexpected start-up during maintenance or guard removal, including requirements for lockout and tagout (LOTO) procedures. Power sources must be isolated, and machinery must remain in a safe state until it is ready to restart.
Compliance with these standards is not a one-time event at installation. Guarding systems must be regularly inspected and maintained to remain effective. If a guard is damaged, misaligned, or bypassed, the compliance obligation is not met, regardless of what was originally installed. This ongoing maintenance requirement is one of the strongest arguments for investing in a high-quality, durable guarding system from the outset.
State and territory WHS regulators, including SafeWork NSW, WorkSafe Victoria, and Workplace Health and Safety Queensland, actively inspect industrial facilities for machinery guarding compliance. Inspectors assess whether:
• Physical barriers provide adequate separation between personnel and hazardous equipment
• Access points are controlled and include lockable entry systems
• Guarding systems are structurally sound and appropriate for the risk level
• Layouts allow safe supervision without exposing workers to machine hazards
• Guards are being regularly inspected and maintained
Penalties for non-compliance are significant and indexed annually. Under the model WHS Act, a category 2 offence (the most prosecuted tier, requiring only that a breach exposed someone to a risk of death or serious injury) can attract fines of close to $2.4 million for a body corporate. Individual officers also carry personal liability. Beyond financial penalties, the reputational and human cost of a serious workplace incident is considerable.
The hierarchy of controls places engineering controls above administrative measures for good reason. Physical guarding does not rely on worker behaviour or supervision. It creates a reliable, consistent barrier between people and danger, regardless of shift patterns, fatigue, or distraction.
For machinery and automated equipment, this means installing robust perimeter guarding systems that:
• Physically prevent unauthorised access to hazardous zones
• Maintain visibility for supervision and monitoring
• Include controlled access gates with lockable latches
• Can be configured to suit the specific layout of your facility
• Are built to withstand the demands of an industrial environment
• Can be reconfigured as operations and equipment change over time
Mesh-PRO by Verge Safety Barriers is a heavy-duty machinery guarding and perimeter safety system designed specifically for Australian industrial environments. Built with a welded steel frame and high-visibility mesh infill, Mesh-PRO delivers the physical separation your WHS obligations require, without compromising visibility or workflow.
Available in 2000mm and 1200mm heights, the system suits a wide range of applications, from full robotic cell enclosures and CNC machine guarding through to conveyor line separation and automated equipment zones. Its modular design means it can be configured to suit virtually any floor plan, and the range of posts, panels, gates, and brackets allows for controlled access points that meet regulatory requirements.
The 2000mm system is suited to high-risk machinery and robotic cells where tall barriers are required to prevent reach-over or climbing. The 1200mm system is ideal for lower-risk machine guarding, conveyor lines, and general equipment separation where visibility and workflow are a priority.
All Mesh-PRO gates include lockable latches, providing controlled access for authorised personnel while maintaining the integrity of the guarded zone.
Not all safety barriers are created equal, and not all of them are built here. Mesh-PRO is proudly designed and manufactured in Australia, giving customers local supply, local support, and a product engineered specifically for Australian conditions and compliance requirements.
Choosing Australian made means faster supply, no overseas supply chain uncertainty, and the confidence of knowing your guarding system was built to the same quality standards your workers deserve. Backed by decades of industry experience, Verge Safety Barriers supports Australian manufacturers and industrial operators with solutions that are built to last in demanding environments, including cold storage, washdown areas, and corrosive industrial settings.
Machinery guarding audits, near misses, and serious incidents all tend to reveal the same thing: the risk was known, but action was delayed. The WHS Act does not allow for that margin. If your facility has gaps in its machinery guarding, now is the time to address them.
Mesh-PRO makes compliance straightforward. Its modular system is fast to install, easy to reconfigure as your operations evolve, and built to the standard Australian industrial environments demand. View our Mesh-PRO range here.
