Origin
Where the RAG system comes from
The Red-Amber-Green system originated with the European racking standard FEM 10.2.04 and was adopted into Australian inspection practice in the early 2010s. AS 4084:2023 now formally references colour-coded severity ratings as the documentation standard for inspection reports across QLD and NSW.
Every reputable inspector — whether engineer, installer or specialist — uses RAG. If your last inspection report only listed "pass" or "fail" without colour ratings or millimetre measurements, it does not meet the AS 4084 documentation requirement.
Tolerances
The mm thresholds for each colour
Tolerances vary by component and by manufacturer, but the table below reflects the conservative defaults used when manufacturer-specific data is unavailable. Always defer to the original equipment manufacturer (OEM) figures if they are tighter.
| Component | Green | Amber | Red |
|---|---|---|---|
| Upright (front-to-back lean) | ≤3 mm per metre | 3–5 mm per metre | >5 mm per metre |
| Upright (side-to-side bow) | ≤3 mm over 1m | 3–5 mm over 1m | >5 mm over 1m |
| Beam deflection (loaded) | ≤L/200 | L/200 – L/180 | >L/180 or permanent set |
| Baseplate gap to slab | 0 mm | 1–3 mm | >3 mm or anchor visible |
| Bracing | Straight | Bent ≤5 mm | Bent >5 mm, missing or fractured |
Response
What to do after each colour rating
- Red — unload the bay immediately, barricade the aisle, isolate the row and book a repair.
- Red — notify the PCBU and log in the incident register within 60 minutes.
- Amber — keep loaded but plan repair within 28 days; reduce load if repair slips.
- Amber — flag the component in the maintenance schedule with a follow-up date.
- Green — record the measurement so the next inspection can detect progression.
- All ratings — photograph the component with a measurement reference in the frame.
Red rating — the 60-minute rule
Documentation
What a compliant RAG report includes
A defensible AS 4084:2023 report includes a site overview, a bay-by-bay damage register, photographs of every Amber and Red component, the inspector's competent-person credentials and a sign-off page. Anything less is hard to defend if a claim or regulator request lands on your desk.
