What Happens During a SEMA Racking Inspection? A Step-by-Step Guide

The inspection starts with a short scoping conversation. We ask for the site postcode, the approximate bay and run count, the number of beam levels, the racking type or types installed, and anything that affects access — chilled or frozen areas, bonded stock, mezzanine or pick-tower structures, restricted working hours, permit requirements.

You do not need to prepare much, and you certainly do not need to empty the racking. Four things help if you have them: any original manufacturer documentation or load tables, the existing load notices, your weekly PRRS inspection records, and a note of any impacts or known damage since the last inspection. Racking inspected as found, loaded and in use, is racking inspected in the condition it actually works in.

If bay references are not already marked on the racking, it is worth doing before the visit. Every finding on the report is tied to a location, and consistent physical references make the report far easier to act on afterwards.

The inspector arrives with identification and accreditation details, completes your site induction and any permit requirements, and then spends a few minutes with whoever knows the warehouse best — normally the PRRS, warehouse manager or shift supervisor.

That briefing covers practical ground: the layout and which runs are in scope, the MHE types in use and the aisles they work in, any known damage or recent impacts, the age of the installation and its manufacturer where known, whether any runs have been extended, reconfigured or built from mixed components, and how the site wants to handle any red-risk finding that comes up during the day.

The inspector also confirms how the day will run around your operation. Inspection works alongside live picking and replenishment; where a specific aisle needs to be quiet for a short period, that is agreed rather than imposed.

The inspector works systematically rather than sampling, following a route that covers every run so that nothing is skipped and every finding can be located precisely.

Uprights are checked over their full height, front and rear face. Out-of-straightness is measured against a straight edge in both planes, and a sharp kink or crease is treated more seriously than a smooth bow of similar amplitude because it concentrates loss of section. Torn or distorted connector holes, sheared or missing bolts, splices, and corrosion causing section loss are all recorded.

Beams are checked for permanent deflection remaining after load is removed, damage or distortion at the end connectors, connector welds, and missing or dislodged safety clips. A beam that looks straight but whose connector has been pulled is a serious defect, because the connection is what transfers load into the frame.

Bracing — horizontal, diagonal and run spacers — is checked for damaged, detached or missing members, including members removed for access and never reinstated. Baseplates and floor fixings are checked for loose, missing or sheared anchors, uneven packing, plates lifting, and cracking in the slab around fixings.

The inspector then assesses the installation rather than the components: beam pitch and configuration against the design intent, aisle widths against the MHE actually in use, frame protection and end-of-run barriers at pinch points, whether load notices match the configuration in front of them, and whether the weekly PRRS records reflect what is visible today. Where notices are missing or out of date, that is flagged for correction — see load notices and racking signage.

Every defect found is classified against the tolerances in BS EN 15635 using the traffic-light system. Green risk means the damage is within tolerance: the location is recorded and monitored at future weekly checks. Amber risk means the component is outside tolerance but judged safe for short-term use: it must be planned and replaced within a defined period, commonly four weeks. Red risk means the component cannot be relied on to carry load: the bay is offloaded immediately and isolated until repaired or replaced.

Because the colour carries an instruction, findings are actionable straight away rather than left to interpretation. The detail behind each grade is set out in red, amber and green racking damage explained.

Red-risk findings are not held back for the report. If the inspector finds a red-rated component, you are told during the visit so the bay can be offloaded and isolated the same day, and the inspector will advise on how to isolate it safely.

Before leaving, the inspector runs through the headline findings with you: how many red items and where, the scale of the amber list, any pattern of recurring damage, and any observations about configuration, load notices or protection that need a decision rather than a repair.

It is also the point to raise questions about your own regime — whether the weekly route covers the right areas, whether your PRRS needs refresher training, whether a particular aisle keeps generating damage. An inspector who has just walked every run of your racking is the best-informed person on site for that conversation.

If your weekly regime is thin or the nominated PRRS has moved on, that is normally addressed alongside the inspection through PRRS training, because an expert report on a site with no interim regime only solves half the problem.

The written report is issued within 48 hours. Every defect appears with its location by bay or run reference, the component affected, what was observed or measured, its classification, a photograph, and a recommended action. Items are prioritised so the order of work is obvious.

The report also covers the installation-level observations: configuration, load notice status, protection, aisle widths and the state of the interim inspection regime. It is written to be read by someone who was not there — an auditor, an insurer, a client's compliance team or an HSE inspector — without needing further explanation.

Aligned to HSG76, BS EN 15635 and SEMA codes of practice, the report is your evidence of inspection under PUWER 1998 regulation 6. Repairs are not included in the inspection and are quoted separately, so findings are never influenced by the value of the remedial work; see damage repair and replacement guidance.

Deal with red items immediately if they have not already been actioned on the day. Give every amber item an owner and a completion date, and sign each one off against the report line when the work is done. Transfer green items onto the weekly PRRS route so they are walked past deliberately.

Look for repeat locations. If the same bays appear year after year, the answer is not another frame — it is a change to traffic layout, aisle width, pick-face position or protection. Where damage keeps happening in areas nobody observes, continuous racking impact monitoring records impacts with time, location and severity between inspections.

Finally, keep the closed-out report with your weekly logs and impact records. That package — inspected, classified, actioned, verified — is what a defensible racking regime looks like on paper. You can see real examples of inspections and their outcomes in our case studies.
