Warehouse Floor Marking Colours in Australia - What Each Colour Means and What the Rules Are

A SafeWork NSW inspector walked through a distribution centre in Ingleburn last year and issued three improvement notices in under an hour. The forklift lanes were yellow - correct. The pedestrian walkways were also yellow. That was the problem. When forklifts and foot traffic share the same colour coding, the entire visual separation system fails. Two workers had already reported near-misses that quarter.

Warehouse floor marking colours in Australia are not decorative. They are a functional safety system governed by Australian Standards and enforced by state WorkSafe authorities. Getting them right is not optional. Getting them wrong creates liability, fails audits, and puts people at risk.

This guide covers every colour used in Australian warehouse floor marking, what each one means, what the standards actually say, the minimum dimensions required, and the mistakes we see most often when we arrive on site to fix jobs done by others.

Quick Answer - What Each Colour Means

If you need the short version before the detail:

• Yellow - Forklift lanes, vehicle traffic routes, caution zones
• White - Pedestrian walkways, general lane markings, bay delineation
• Red - Fire equipment zones, fire extinguishers, hydrants, emergency shutoffs
• Green - First aid stations, safety equipment, emergency exits
• Blue - Mandatory action zones (PPE required areas)
• Orange - Inspection areas, staging zones, temporary hazards
• Black and yellow hatching - Physical hazard zones, keep-clear areas, trip/crush hazards
• Red and white hatching - No-go zones, prohibited areas, fire equipment clearance
• Black and white hatching - Operational boundaries, traffic direction

What the Law Actually Says

There is no single Australian law that prescribes exact warehouse floor marking colours. Instead, the obligation comes from the interaction of several pieces of legislation and standards:

Work Health and Safety Act 2011 (WHS Act) - Applies in all states except Victoria and Western Australia, which have their own equivalent legislation. The WHS Act requires a person conducting a business or undertaking (PCBU) to ensure, so far as is reasonably practicable, the health and safety of workers and others at the workplace. Floor marking is one of the primary controls for managing traffic and pedestrian interaction risks in warehouses.

AS 1318:1985 - SAA Industrial Safety Colour Code - This is the Australian Standard that defines the meaning of safety colours in industrial environments. It establishes that yellow means caution, red means fire or danger, green means safety, and blue means mandatory action. While AS 1318 is not law itself, it is referenced by WHS Codes of Practice and is the benchmark WorkSafe inspectors use when assessing warehouse floor marking compliance.

AS 2444 - Portable Fire Extinguishers and Fire Blankets - Specifies that fire equipment locations must be clearly marked with red identification. Floor markings around fire equipment are typically red or red and white hatching to indicate clearance zones.

Safe Work Australia publishes model Codes of Practice that guide how these obligations are met in practice. The Managing the Risks of Plant in the Workplace Code of Practice specifically addresses traffic management, exclusion zones, and the use of floor markings to separate pedestrians from powered mobile plant like forklifts.

WorkSafe Victoria and equivalent state regulators enforce these requirements through workplace inspections. A colour coding system that does not provide clear visual separation between forklift traffic and pedestrian routes is a commonly cited non-compliance issue.

The 'Reasonably Practicable' Standard

The WHS Act does not say you must use yellow for forklifts and white for pedestrians. What it says is that you must manage risk so far as is reasonably practicable. Floor marking colour coding that follows AS 1318 is considered reasonably practicable by every state regulator. Using a colour system that contradicts AS 1318, or using the same colour for different purposes, is what gets flagged in audits and inspections.

In practical terms, if a WorkSafe inspector walks through your warehouse and sees yellow lines for both forklift lanes and pedestrian walkways, you will receive an improvement notice. The fact that you have lines on the floor is not enough. The lines must communicate the right information to anyone on the floor - including visitors, agency staff, and delivery drivers who have never been to your facility before.

Colour by Colour - What You Need to Know

Yellow - Forklift Lanes and Vehicle Traffic

Yellow is the primary colour for forklift travel lanes and vehicle traffic routes in Australian warehouses. This is established under AS 1318 as the colour for caution and is universally understood in industrial environments.

Yellow floor markings should be used for:

• Forklift travel lanes (both directions)
• Forklift turning areas and intersections
• Loading dock approach lanes
• Vehicle-only zones within the warehouse
• Speed limit markings within forklift lanes

Yellow should NOT be used for pedestrian walkways, storage bay delineation, or any marking that is not related to vehicle traffic or caution. The moment you use yellow for both forklifts and people, you have eliminated the visual separation that the colour system is designed to provide.

Recommended width for forklift lanes is a minimum of 100mm line width, with the lane itself wide enough to accommodate the largest forklift operating in the facility plus a minimum 500mm clearance on each side.

White - Pedestrian Walkways

White is the standard colour for pedestrian walkways in Australian warehouses. It provides clear visual contrast against yellow forklift lanes and against most warehouse floor surfaces (grey concrete, sealed concrete, epoxy coatings).

White floor markings should be used for:

• Pedestrian walkways and footpaths through the warehouse
• Pedestrian crossing points across forklift lanes
• General bay delineation and storage area boundaries
• Visitor routes and evacuation paths (in combination with green for exit points)

Pedestrian walkways must be wide enough for two people to pass comfortably - a minimum of 1,000mm clear width is recommended, with 1,200mm or more preferred in high-traffic facilities. Line width should be a minimum of 100mm.

At pedestrian crossing points where walkways cross forklift lanes, additional marking is required. This typically includes zebra-style hatching or dashed crossing lines, combined with signage and in some facilities, mirrors or sensors at blind corners.

Red - Fire Equipment Zones

Red floor marking in a warehouse means one thing: fire equipment. This is defined by AS 1318 and reinforced by AS 2444 for portable fire extinguisher and fire blanket locations.

Red markings are used for:

• Clearance zones around fire extinguishers (typically a 1,000mm radius semicircle or square on the floor beneath the extinguisher)
• Clearance zones around fire hydrants and hose reels
• Fire panel access zones
• Emergency shutoff access zones
• Sprinkler riser room access

The critical rule with red floor markings is that the marked zone must remain clear at all times. No pallets, no equipment, no parked forklifts. A fire extinguisher with pallets stacked in front of it is a compliance failure that WorkSafe inspectors identify immediately.

Red and white hatching is used for higher-emphasis prohibition zones - areas where no access or storage is permitted under any circumstances.

Green - Safety Equipment and Emergency Exits

Green indicates safety in Australian industrial colour coding. In warehouse floor marking, green is used sparingly but specifically for:

• First aid station locations
• Safety shower and eyewash station locations
• Emergency exit paths (often in combination with photoluminescent strip marking for power-failure visibility)
• Safety equipment storage areas

Green floor markings are less common than yellow, white, and red in most warehouses, but they are critical where they are used. First aid stations and safety showers must have clear floor access at all times.

Hazard Hatching - Black/Yellow and Red/White

Hazard hatching uses alternating diagonal stripes (typically at 45 degrees) to indicate specific hazard types:

Black and yellow hatching indicates physical hazards - areas where there is a risk of collision, tripping, falling, or being struck. Common applications include:

• Column bases and structural steelwork at floor level
• Dock edges and loading bay lips
• Areas around moving plant or machinery
• Step-down areas and changes in floor level
• Forklift exclusion zones around pedestrian areas

Red and white hatching indicates prohibition - areas where entry or storage is strictly forbidden. This is stronger than black and yellow and is typically used for:

• Fire equipment clearance zones (alternative to solid red)
• Electrical switchboard access zones
• Emergency exit clearance areas
• No-storage zones beneath sprinkler heads (per BCA requirements)

Minimum Dimensions for Warehouse Floor Markings

Zone Type	Minimum Line Width	Minimum Zone/Lane Width	Notes
Forklift travel lane	100mm	Forklift width + 1,000mm (500mm each side)	Wider for counterbalance forklifts and reach trucks
Pedestrian walkway	100mm	1,000mm minimum (1,200mm preferred)	Must allow two people to pass
Pedestrian crossing	100mm	1,200mm minimum	Zebra hatching or dashed lines across forklift lanes
Fire extinguisher clearance	100mm	1,000mm radius or 1,000mm x 1,000mm square	Must remain unobstructed at all times
Hazard hatching (column bases)	100mm stripe width	Minimum 300mm from hazard edge	45-degree alternating stripes
Dock edge warning	100mm stripe width	Full width of dock opening, 1,000mm depth	Black/yellow hatching at all loading dock edges
Exclusion zone (machinery)	100mm	Per risk assessment - typically 1,000mm minimum from moving parts	Hatching pattern based on hazard type

Common Colour Mistakes We Fix

After completing over 5,000 warehouse floor marking projects across Australia, these are the six most common colour-related mistakes we encounter when we arrive on site:

1. Yellow for everything. The most common mistake. Facility managers or previous contractors use yellow for forklift lanes, pedestrian walkways, bay delineation, and even fire equipment zones. When everything is yellow, nothing is communicated. We strip the non-compliant markings and re-mark with the correct colour system.

2. No colour contrast between forklift and pedestrian zones. Some facilities use yellow for forklifts and a pale cream or off-white for pedestrians. Under warehouse lighting, especially with dust or oil film on the floor, the two colours become indistinguishable. White needs to be true white against yellow, not cream.

3. Red used for general hazard instead of fire only. Red means fire in AS 1318. Using red for general warning or keep-clear zones that are not fire-related confuses the system. General physical hazards should use black and yellow hatching, not red.

4. No hatching at dock edges. Loading dock lips are one of the highest-risk areas in any warehouse. The edge should be marked with black and yellow hazard hatching for the full width of the opening. A surprising number of facilities have no marking at all.

5. Fire extinguisher floor markings obscured or missing. Pallets stacked over red floor markings, or red markings that have worn away and not been repainted. Both are common findings in WorkSafe inspections.

6. Inconsistent colour system across multiple buildings. Facilities with multiple warehouse buildings that use different colour conventions in each building. If a forklift operator moves between buildings, the colour system must be consistent across all of them.

Getting Your Warehouse Floor Marked Correctly

A compliant warehouse floor marking job starts with a floor plan review and risk assessment - not with a paint machine. Before any marking goes down, the layout needs to account for:

• Forklift traffic flow patterns and turning radii
• Pedestrian routes from entry points to work areas
• Fire equipment locations and required clearance zones
• Loading dock approach and staging areas
• Storage bay dimensions and aisle widths
• Intersection treatments where forklifts and pedestrians cross paths

The colour system needs to be documented in a site traffic management plan. This plan should be displayed at facility entry points and included in site induction materials so that everyone entering the warehouse - staff, visitors, delivery drivers, and contractors - understands what each colour means.

At Line Marking Australia, we provide a complete colour-coded floor plan as part of every warehouse line marking project. The plan documents every colour, its meaning, and the standard it references. This document becomes part of your compliance evidence for WorkSafe audits and is updated whenever the floor layout changes.

Frequently Asked Questions

What colour should forklift lanes be in an Australian warehouse?

Yellow. Under AS 1318, yellow is the designated colour for caution and vehicle traffic routes. Forklift lanes, turning areas, and vehicle-only zones should all be marked in yellow. This must be visually distinct from pedestrian walkway markings, which are typically white.

Is there a legal requirement for specific floor marking colours in warehouses?

There is no single law prescribing exact colours. However, the WHS Act requires workplaces to manage risks so far as is reasonably practicable, and AS 1318 defines the industrial safety colour code. Using a colour system consistent with AS 1318 is considered the reasonably practicable standard by all state WorkSafe authorities. Non-compliant colour coding is routinely cited in improvement notices.

What does red floor marking mean in a warehouse?

Red floor marking indicates fire equipment locations and fire-related clearance zones. Under AS 1318 and AS 2444, red is designated for fire danger and fire equipment identification. Red floor zones around extinguishers, hydrants, and fire panels must remain clear and unobstructed at all times.

How wide should pedestrian walkway lines be in a warehouse?

Line width should be a minimum of 100mm. The walkway itself should be a minimum of 1,000mm clear width to allow two people to pass, with 1,200mm preferred in higher-traffic areas. These dimensions should be confirmed against your facility's specific risk assessment and traffic management plan.

How often should warehouse floor markings be repainted?

It depends on traffic volume, surface type, and the product used. Standard waterborne traffic paint in a high-traffic warehouse typically lasts 12-24 months. Two-pack epoxy lasts 3-7 years. The key trigger for remarking is when lines are no longer clearly visible and legible from the normal viewing distance of a forklift operator or pedestrian. For more detail, see our guide on how long line marking lasts.
