A Guide to Compliance and Best Practices
When it comes to workplace safety in Australia, machine guarding is a critical aspect that cannot be overlooked. Machinery is an essential part of many industries, but it also presents a range of hazards if not properly managed.
Machine guarding is designed to protect operators and other workers from a range of risks including:
- Moving parts
- Flying debris
- Unexpected start-ups
To prevent these Australia has developed comprehensive standards that set out the requirements for effective machine guarding.
In this article, we’ll explore the key machine guarding standards in Australia, examine why they are so important, and provide practical advice on how businesses can implement these standards to maintain a safe working environment.

What Are Machine Guarding Standards?
Machine guarding standards are a set of guidelines that define how operating machinery should protect against injuries. These standards outline the different types of guards, where they should be placed, and how they should function to keep workers safe.
The key Australian Standards related to machine guarding are found in the AS 4024.1 series, which is the most widely referenced set of guidelines for machinery safety in Australia.
Key Australian Standards for Machine Guarding
The AS 4024.1 series is based on international (ISO/EN) standards but is adapted to meet the specific needs and regulatory requirements of the Australian workplace. These standards cover everything from basic guard design to advanced control systems, and are relevant to all industries involved in machining.
1. AS/NZS 4024.1601:2014 – Guards – General Requirements
General principles for designing and constructing guards. It specifies different types of guards, including fixed, movable, and interlocked guards, and outlines how each should be applied depending on the machinery and the type of hazard involved.
Guards must:
- Be robust
- Be appropriately positioned
- Minimise gaps
- Prevent access to dangerous areas
2. AS/NZS 4024.1602:2014 – Interlocking Devices
Interlocking devices play a crucial role in machine guarding by ensuring that machinery cannot operate unless guards are in place. For example, if a guard is removed, the machine must automatically stop to prevent any potential hazards.
This standard covers:
- Principles of designing devices
- Principles of selecting interlocking devices
- Making sure that they are reliable
- Making sure they cannot be bypassed easily
3. AS/NZS 4024.1603:2019 – Prevention of Unexpected Start-Up
One of the leading causes of machine-related injuries is the unexpected start-up of machinery. This standard outlines measures to prevent machines from starting when guards are removed for maintenance or other purposes.
The implementation of Lock Out Tag Procedures (LOTP) can ensure employees effectively isolate machines to prevent unexpected startup. Physical locks and tags act as a deterrent to any manipulation of the machine’s safety mechanisms.
Key points:
- Start-up prevention must always be active
- Power sources must be isolated
- Machinery remains in a safe state until it is ready to be restarted
4. AS 4024.1503:2014 – Control Systems and Safety-Related Parts
Effective machine guarding goes beyond physical barriers. This standard provides guidance on designing control systems that include safety-related components. It covers the principles for reliable control systems that ensure the integrity of guards and overall machine safety.
Why Machine Guarding is Important
Machine guarding is essential because it directly addresses some of the most common and dangerous hazards associated with operating machinery.
The key risks that machine guarding helps mitigate include:
- Contact with moving parts such as gears, spindles, or belts. Guards prevent this contact by creating a physical barrier between workers and the dangerous components.
- Ejection of parts or debris at high speeds. Proper guarding contains these materials and prevents them from causing injury.
- Unexpected start-ups. Effective guards, combined with interlocking devices and control systems, keep machines offline unless all safety conditions are met.
- Maintenance often requires guards to be removed, which introduces additional risks.
By addressing these risks, machine guarding helps create a safer workplace, reducing the likelihood of injuries and fatalities.
Best Practices for Implementing Machine Guarding in the Workplace
Implementing effective machine guarding requires more than just installing physical barriers. It involves careful planning, risk assessments, and ongoing management.
Here are some best practices for ensuring compliance with Australian Standards:
Risk Assessments
- Conduct regular risk assessments to identify potential hazards
- Assessments should be comprehensive and consider all aspects of machine operation
Customised Guarding Solution
- Guards should be customised to suit the specific machinery and the operational environment
- Bespoke guards can fit perfectly around complex machinery and restrict employees accessing danger points and hazardous areas
Training and Procedures
- All operators and maintenance personnel should receive thorough training
- All staff should have correct procedures for safely operating and maintaining machinery
Regular Maintenance and Inspections
- Regular inspections should be carried out to check for wear and tear, misalignment, or damage
- As workers regularly remove guards to access parts of the machine or if it interferes with their work, they must be frequently inspected
- Any issues should be addressed immediately to provide adequate protection
Safety Culture and Reporting
- Establish a safety culture where workers feel comfortable reporting any issues
- Encourage open communication and involve employees in identifying and resolving safety concerns
Compliance and Legal Obligations in Australia
In Australia, compliance with machine guarding standards is not optional—it’s a legal requirement. The Work Health and Safety (WHS) Act mandates that businesses take all reasonable steps to protect workers from harm. Failure to comply with the AS 4024 standards can result in hefty fines, legal action, and, most critically, serious injury or death.
By adhering to these standards, businesses can ensure that they are:
- Operating within the law
- Protecting their workers
- Demonstrating a commitment to safety
- Reducing downtime due to accidents
- Lowering insurance premiums
Training and Procedures for Safe Operation of Machinery
To fully benefit from machine guarding, businesses need to implement clear procedures and with consistent training. Standard Operating Procedures (SOPs) should be established for operating machinery, with specific guidelines on how to handle guards during both normal operations and maintenance.
Training should be ongoing, with regular refreshers to reinforce the importance of guarding and ensure that workers stay up to date with the latest safety practices.
