Racking Inspection Checklist — What a SEMA-Aligned Inspector Checks
Pallet racking is classed as work equipment under the Provision and Use of Work Equipment Regulations 1998 (PUWER), which means it must be suitable for its purpose, maintained in a safe condition, and inspected. HSG76 — the HSE's guidance on warehousing and storage — recommends that pallet racking is inspected by a technically competent person at least once every twelve months, in addition to routine visual checks by trained warehouse staff.
This is the full checklist a SEMA-aligned, SARI accredited inspector works through on site — the same framework your own PRRS (Person Responsible for Racking Safety) should be using for weekly visual checks.
The SEMA Traffic Light Classification System
Every defect a SEMA-aligned inspector records is classified using a three-tier traffic light system. The rating determines what action is required and how quickly.
No significant damage identified. No action required — the component remains in service.
Damage identified that should be monitored or repaired within a set timeframe — commonly four weeks. The bay may need its load reduced in the meantime. If it is not repaired within the timeframe, the classification escalates to red.
Damage severe enough that the bay must be unloaded and taken out of use immediately. It must not be re-loaded until the damaged component has been replaced or repaired to the manufacturer's specification.
What Gets Checked: The Full Checklist
A SEMA-aligned inspection is a systematic, component-by-component walk of every run of racking on site. These are the eight categories inspected on every audit.
1. Upright frames
- Bends, dents or buckling in any upright section — most commonly at the lower 1m from forklift impact.
- Splits or cracking in welds where diagonals meet uprights.
- Corrosion, particularly on external, cold-store or chemical-exposed installations.
- Twisting or out-of-plumb frames beyond EN 15635 tolerance.
2. Beams and beam connectors
- Bent, twisted or visibly deflected beams under load — beams should return flat when unloaded.
- Safety clips or locking pins present and correctly engaged at every beam end.
- Damage to beam-end connectors, including cracked welds or sheared teeth.
- Correct beam type and length for the bay — no ad-hoc substitutions.
3. Base plates and floor fixings
- Cracked or deformed base plates.
- Base plates lifting from the floor slab.
- Missing, loose or corroded floor bolts.
- Correct anchor type and specification for the floor construction.
4. Bracing
- Damage to diagonal or horizontal bracing from impact.
- Missing bracing components.
- Loose, missing or incorrectly torqued bracing bolts.
5. Load notices
- A load notice is present on every run of racking.
- Signage is legible and undamaged.
- The notice matches the current beam configuration and the loads actually in use.
- Notice has been re-issued after any reconfiguration of beam levels.
6. Row spacers and guards
- End-of-aisle barriers present and undamaged.
- Column guards / upright protectors fitted where required and intact.
- Row spacers correctly installed between back-to-back runs.
7. Pallets
- Pallets in use are suitable for the racking system and load type.
- No damaged, broken or non-standard pallets contributing to instability.
- Loads are not overhanging beams or contributing to overloading.
8. General housekeeping
- Racking is being used as designed — no makeshift storage above top beams.
- No signs of overloading or uneven loading across the bay.
- Sprinklers, lighting and emergency routes are not obstructed by stock.
- Aisles clear, floors in good condition, no trip hazards at the base of uprights.
Common Issues Found During Racking Inspections
Certain faults recur across UK warehouses regardless of sector or racking manufacturer. The list below covers the issues a SEMA-aligned inspector encounters most frequently, why each one matters, and the action required when it is identified.
1. Overloading
- Why it matters
- Exceeding the load capacity stated on the load notice is one of the most common root causes of racking damage. Bent beams and buckled uprights are the most common visible symptom.
- What to do
- Redistribute the load immediately, verify the actual load against the current load notice, and retrain warehouse staff on safe loading and unit load weights.
2. Missing or disengaged safety clips
- Why it matters
- Beams that aren't positively locked to the upright can lift out of their connectors when a pallet is caught during placement or retrieval — potentially causing a full bay collapse.
- What to do
- Replace missing or damaged clips immediately and treat as a priority defect. Every beam end must have its clip correctly engaged before the bay is reloaded.
3. Forklift impact damage
- Why it matters
- Forklift impact is the single most common cause of racking damage in UK warehouses, typically affecting the lower 1m of upright frames. Even minor impacts can significantly reduce an upright's load-carrying capacity.
- What to do
- Isolate the damaged bay, do not reload until repaired by a competent installer, and consider fitting column guards or end-of-aisle barriers to prevent recurrence.
4. Corrosion
- Why it matters
- Corrosion is more common in cold stores, coastal locations, food and chemical sites, and warehouses with washdown cleaning regimes. Structural section loss reduces load-carrying capacity even when the damage looks cosmetic.
- What to do
- Monitor closely, treat surface corrosion early, and replace any component showing structural section loss to the manufacturer's specification.
5. Missing or illegible load notices
- Why it matters
- A clear load notice is a legal requirement under PUWER 1998 and essential for warehouse staff to know the safe working load of each bay and level. Notices missing after a reconfiguration are a particularly common finding.
- What to do
- Reissue signage immediately and ensure it matches the actual current beam configuration — not the original as-installed layout.
6. Base plate and floor fixing failure
- Why it matters
- Cracked base plates, or loose or missing floor bolts, compromise the racking's stability under lateral load — the very loads a racking system relies on floor fixings to resist.
- What to do
- Isolate the affected bay and have base plates and fixings repaired or replaced to specification by a competent installer before the bay is reloaded.
7. Incorrect or ad-hoc configuration changes
- Why it matters
- Beams moved to non-standard heights, or bays reconfigured without re-issuing load notices, silently invalidate the original design calculations and the current load notice.
- What to do
- Any reconfiguration should trigger a fresh load notice and, ideally, a competent-person review before the bay is put back into use.
HSE guidance (HSG76) and the Health and Safety at Work Act 1974 place a clear duty on employers to maintain storage equipment — including pallet racking — in a safe condition. Racking collapse incidents investigated by HSE frequently cite inadequate or absent inspection regimes as a contributing factor. A documented programme of daily visual checks, PRRS-led periodic checks, and an annual expert inspection by a SARI accredited inspector is the recognised way to demonstrate that duty has been met.
Who Should Carry Out a Racking Inspection?
SEMA and HSG76 describe three tiers of inspection. All three are expected to be in place — the annual expert inspection does not replace the routine checks that happen in between.
1. Daily and weekly visual checks
Carried out by trained warehouse staff. Any impact damage or defect should be reported immediately to the nominated PRRS and the affected bay isolated pending review.
2. Periodic checks by the PRRS
The Person Responsible for Racking Safety is a nominated, trained employee who carries out documented weekly inspections and maintains the site's damage log.
3. Annual expert inspection
Carried out at least once every twelve months by a technically competent person. In the UK the recognised benchmark is a SEMA-aligned, SARI accredited inspector. This is the report an HSE inspector will ask to see.
What Happens After an Inspection?
Once the on-site walk is complete, the inspector produces a written report. Typically:
- A written report is issued — typically within 48 hours of the inspection.
- Every defect is photographed and classified as red, amber or green.
- Clear repair recommendations are provided against each defect.
- The report is retained by the duty holder as evidence of compliance with PUWER and HSG76.

Frequently asked
How often should racking be inspected?
HSG76, the HSE's guidance on warehousing and storage, recommends that pallet racking is inspected by a technically competent person at least once every 12 months. This annual expert inspection sits alongside routine visual checks by warehouse staff and periodic checks by a nominated Person Responsible for Racking Safety (PRRS).
Who can carry out a racking inspection?
Under PUWER 1998 and HSG76, the annual expert inspection must be carried out by a technically competent person. In the UK the recognised route to competence is SEMA's SARI (SEMA-Aligned Racking Inspector) scheme. Daily and weekly visual checks can be carried out by trained warehouse staff, typically overseen by a nominated PRRS.
What is a SARI accredited inspector?
A SARI is a SEMA-Aligned Racking Inspector — an individual who has passed SEMA's training programme and external assessment, holds professional indemnity insurance, and is subject to ongoing continuing professional development and re-assessment. SARI is the UK's recognised benchmark for the 'competent person' referenced by HSE in HSG76.
What happens if racking fails inspection?
Defects are classified using SEMA's red/amber/green traffic light system. Red-rated damage means the affected bay must be unloaded and taken out of use immediately until it is repaired. Amber-rated damage should be repaired within a set timeframe (commonly 4 weeks) and the bay's load may need to be reduced in the meantime. Green means no significant damage and no action is required.
