Select the guard type
Decide where fixed guarding suits infrequent access and where movable guarding is needed for genuine operational or maintenance access.
FIXED + MOVABLE GUARDS
AS/NZS 4024.1601 fixed and movable machine guards
The core guard-design page for engineers planning the physical boundary: what the guard must do, how it fits the machine and how it remains effective in service.
FROM STANDARD TO SCOPE
Four conversations to have before the layout is locked
Use AS/NZS 4024.1601 to shape a durable guard system around the machine and the way people use it. The exact decisions still depend on the machine, tasks, risk assessment and current authorised standard.
Design the boundary
Consider coverage, retention, mounting, openings, visibility and the ways material or parts could be ejected.
Design for real use
Account for cleaning, adjustment, inspection and maintenance so the guard is less likely to be removed or defeated.
Specify information and checks
Capture installation, use, inspection and maintenance information needed to keep the guard effective over its life.
WHY IT MATTERS
Good guarding protects the job—and still lets the job happen
The strongest layout is rarely the one with the most steel. It is the one that creates a clear physical boundary, supports required access and remains practical enough to stay in place.
THE COMPLETE DESIGN PICTURE
One standard rarely works alone
Risk assessment, physical guards, safety distances, interlocking, unexpected start-up and emergency-stop functions are connected. Follow the regional hub to move between the relevant guides without losing the project context.
Edition and jurisdiction note
AS/NZS 4024.1601:2024 is the current joint publication identified publicly and is identical to ISO 14120:2015. Confirm current status before specifying. Standards and guidance support—not replace—a project-specific risk assessment, applicable WHS/HSWA duties, regulator guidance and competent professional advice.
COMMON QUESTIONS
AS/NZS 4024.1601 FAQs
Does this standard cover interlock device selection?
It addresses guards themselves. Interlocking devices associated with guards are treated separately in AS/NZS 4024.1602.
Does a fixed guard always mean welded in place?
The relevant classification depends on how the guard is held and removed, not a marketing label. Confirm the design against the current standard and risk assessment.
Can I use a modular perimeter system?
Modular systems can support many fixed and movable guard layouts, but suitability depends on the machine hazards, access, safety distances, mounting and the complete safeguarding system.
