Racking Inspection Requirements Under AS 4084

AS 4084 Steel Storage Racking establishes the Australian standard for the design, manufacture, and use of steel storage racking systems, including inspection and maintenance requirements. The standard requires three levels of inspection to be implemented across all racking installations. Daily visual checks should be conducted by warehouse personnel to identify obvious damage, displaced beams, missing safety clips, and overloaded or incorrectly placed pallets. Monthly inspections by a nominated competent person must systematically assess every accessible component for damage, deformation, and corrosion using the traffic light damage classification system. Annual expert inspections must be conducted by a person with specialist knowledge of racking design and structural behaviour, typically a racking engineer or specialist racking inspector. The annual inspection should include measurement of upright verticality, assessment of floor slab condition, verification of load ratings against actual stored weights, and a comprehensive review of the racking system's structural integrity. Each inspection level produces documented findings with corrective actions tracked to completion.

The traffic light damage classification system provides a consistent framework for assessing racking damage severity and determining the required response. Green classification indicates minor damage such as superficial scratches, minor paint damage, or cosmetic dents that do not affect the structural capacity of the component. Green items are recorded and monitored at subsequent inspections but do not require immediate action. Amber classification indicates moderate damage where the component remains functional but the damage could progress to structural compromise if not addressed. Amber items include measurable deformation of uprights, bent beam connectors, and missing safety clips. Amber items require corrective action within a defined timeframe, typically 28 days, and may require load reduction in the affected bay until repairs are completed. Red classification indicates critical damage where the structural integrity of the component is compromised and failure could occur under load. Red items include significantly deformed uprights, displaced beams, cracked welds, and any damage that has caused visible lean in the racking structure. Red items require immediate action — the affected bay must be unloaded and isolated from use until the component is repaired or replaced by a qualified racking contractor.

Every racking installation must display load rating signage that is visible, legible, and accurately reflects the rated capacity of the racking configuration. Load ratings are specific to the particular combination of upright frame size, beam length, beam connector type, number of beam levels, and seismic zone. Any change to the racking configuration — including adding beam levels, changing beam lengths, or replacing damaged components with non-original parts — requires the load rating to be recalculated and signage updated. PCBUs must implement systems to verify that actual stored loads do not exceed displayed load ratings, which typically involves weighing a representative sample of pallets and comparing weights against the rated beam and bay capacities. Overloading is one of the most common causes of racking failure and is frequently identified during inspections. A systematic approach to load control includes pallet weight verification at goods receiving, bay load rating signage at every racking bay, and operator training that covers load rating awareness and overloading consequences. Documentation must include the original racking design certification, load rating calculations for every racking configuration, and evidence that actual loads are monitored against rated capacities.

An effective racking inspection program requires a corrective action tracking system that ensures identified damage is repaired within defined timeframes and repairs are verified as compliant. Each corrective action should be assigned to a named responsible person with a clear due date based on the damage classification — immediate for red, within 28 days for amber, and monitored at next inspection for green. The tracking system should capture the location of the damage using a consistent bay and level numbering system, a photograph of the damage, the classification assigned, the corrective action required, the responsible person, the due date, and the completion date with verification evidence. Overdue corrective actions should trigger escalation to senior management because unrepaired racking damage represents a serious risk of catastrophic failure. Repair work must be conducted by qualified racking contractors using original or engineer-approved replacement components, and completed repairs must be inspected and signed off by a competent person before the bay is returned to service. The corrective action register provides critical evidence of due diligence that demonstrates the PCBU is actively managing racking safety and responding to identified deficiencies.
