Under Australian WHS regulations, warehouse guardrails are required wherever a risk assessment identifies a foreseeable chance of a worker being struck by mobile plant, most often a forklift.
The regulations do not hand you a floor plan. They hand you a duty. This guide translates that duty into a zoning plan you can document and defend.
It covers why zoning beats a site-wide barrier standard, the zones that appear in almost every risk assessment, how load ratings are chosen, and how to run the assessment on your site.
What Guardrail Zoning Actually Means
Guardrail zoning is the practice of matching each area of a warehouse to a barrier type and load rating suited to the specific risk in that area, rather than installing one barrier standard across the whole site.
The weaker approach is common. A near miss or an inspection finding triggers a barrier order; the barrier goes in where the incident happened, and the rest of the floor stays as it was. Reactive placement leaves gaps and produces no record of why one zone was protected and another was not.
Zoning starts from the general WHS duty of a person conducting a business or undertaking (PCBU) to eliminate or minimise risk so far as reasonably practicable. Guardrails are one control among several, alongside line marking, bollards, speed limits and gated crossings. Where the risk is a forklift striking a person or a structure, a physical barrier offers the highest level of protection.
The WHS Framework Behind Warehouse Barrier Requirements
The model WHS regulations do not list guardrail placements. Search the regulations for the word ‘guardrail’, and you will come up short.
What they set is an outcome. Regulation 215 of the model WHS Regulations requires the person with management or control of a powered mobile plant to ensure it does not collide with pedestrians or other powered mobile plant. The regulation names the result, not the control.
The details for meeting that duty are in two Safe Work Australia documents.
The first is the model code of practice, managing the risks of plant in the workplace. It identifies physical barriers as an accepted control for separating pedestrians from operating mobile plant. An approved code of practice is admissible in court as evidence of what is reasonably practicable. If a guardrail decision is questioned after an incident, the code is the document your site will be measured against.
The second is traffic management: a guide for warehousing. It is guidance material from the same regulator, and it deals specifically with segregating pedestrian and vehicle routes inside a warehouse. Follow both. Cite the code of practice when you need the benchmark that a court would apply.
Victoria runs its OHS Act and regulations rather than the model WHS laws. The duty to separate pedestrians from mobile plant, and the accepted controls are the same in substance.
Warehouse Zones That Typically Require Guardrails
The same handful of zones comes up in almost every warehouse risk assessment, because they are where pedestrian presence and mobile plant movement overlap most often.
Loading dock and dock leveller edges
Forklifts operate at their highest speed and load here, and the dock edge adds a drop to the impact risk. This zone is rarely left out of a risk assessment.
End of aisle racking
Racking ends sit directly in a forklift’s turning path. A barrier here protects the worker crossing the aisle and the racking structure behind it. AS 4084, the steel storage racking standard, calls for upright protection at aisle ends, and a guardrail set in front of the upright is one accepted way to provide it.
Pedestrian walkway boundaries
Wherever a marked walkway runs alongside an active forklift lane, a physical barrier does what paint alone cannot. It stops a plant operator drifting into the walkway during a moment of inattention.
Plant rooms, switchboards and gas cylinder storage
These areas combine a WHS obligation with an asset protection interest. An impact here risks a worker and critical site infrastructure at the same time.
Mezzanine and dock platform edges where the plant operates below
Where forklifts or trucks operate at the lower level, a barrier at the slab edge protects the structure and the people working beneath it. Fall prevention for workers on the platform itself is a separate requirement under AS 1657 and sits outside the scope of a vehicle impact barrier.
For a deeper breakdown of how to prioritise these areas when the budget forces a phased rollout, read our Top 5 Warehouse Guardrail Zones article.
Choosing Guardrail Load Ratings and Standards
The barrier’s load rating should match the mass and likely speed of the plant operating nearby, not a single-site-wide default.
No Australian standard classifies warehouse guardrails by load. The benchmark specifiers use is the vehicle barrier loading in AS/NZS 1170.1. Kwik-Guard® is independently crash tested against those loads at APV-T, a NATA-accredited facility:
Configuration | Tested load | Typical warehouse zone |
Single Height Top Mount (Class 1 and Class 3) | 30 kN (Type F) | Light traffic areas, walkway boundaries, plant rooms |
Double Height Top Mount (Class 1 and Class 3) | 40 kN (Type G) | Medium forklift traffic, racking ends, dock aprons |
240 kN Single Height Top Mount | 240 kN | Heaviest vehicle exposure, truck routes and dock edges |
A 240 kN rating isn’t a standard warehouse requirement. Under AS/NZS 1170.1, it applies to long downward ramps over 20 metres—though it remains the top choice for heavy vehicle impact areas.
Always ask for independent crash test certification. A load rating on a spec sheet is meaningless without NATA-accredited test results.

How to Run a Guardrail Risk Assessment
Skip the vague safety directives. Follow this 4-step process to build a compliant zoning plan:
- Map traffic flows. Grab a floor plan and mark every spot where pedestrian walkways cross forklift routes.
- Inspect during peak operational hours. Traffic risks look very different during despatch shift changes than during quiet morning audits.
- Talk to floor workers. Your team on the floor knows where the near-misses happen long before audit reports pick them up.
- Document your reasoning. Record why each barrier type was chosen. This documentation proves you took ‘reasonably practicable’ steps if you are inspected.

For typical open-deck and rooftop applications, the specification usually comes back to four practical requirements: documented performance, installation speed, repairability and compatibility with the structure.
The guardrail addresses each without adding the dead load of a concrete barrier.
Guard-R’s Kwik-Guard® range includes 30 kN, 40 kN and 240 kN options across Classes 1 to 6, with single-height edge mount, double-height and 240 kN top-mount configurations.
Kwik-Guard® is Australian-made and independently crash-tested by APV-T, a NATA-accredited facility, against the impact loads in AS/NZS 1170.1.
That gives the project team a defined system to specify against the required load rather than treating the barrier as a detail to resolve later.
Frequently Asked Questions
What is warehouse guardrail zoning?
Guardrail zoning matches specific warehouse zones with tailored barrier types and load ratings based on risk level, rather than taking a costly one-size-fits-all approach.
Are warehouse guardrails required by Australian WHS law?
While regulations don’t explicitly name ‘guardrails’, Regulation 215 mandates that mobile plant collisions with pedestrians be prevented. Safe Work Australia lists physical barriers as an accepted control measure, making un-barrier-protected high-risk zones nearly impossible to defend after an incident.
What load ratings do warehouse guardrails need?
Load ratings must align with vehicle mass and speed. AS/NZS 1170.1 standards benchmark 30 kN for light traffic zones and 40 kN for medium forklift traffic. Always demand NATA-accredited test reports to verify these ratings.
Which areas should be prioritised first?
Focus first on loading docks, aisle-end racking, plant rooms, and pedestrian walkways—where heavy vehicle traffic and worker foot paths cross most frequently.
How do I start a site risk assessment?
Map traffic flows, highlight high-risk intersection points, walk the floor during peak operations, and gather feedback directly from operational team members.
