What to Do If Your Pallet Racking Is Damaged — The Complete Guide

Forklift impact is the most common cause of pallet racking damage in UK warehouses. When it happens — and in any busy warehouse it will happen — the response in the minutes and hours that follow decides whether you have a contained repair or a serious incident. This guide sets out the correct sequence, the standards that govern it, and the tolerances a competent person will measure against.

Why the First Hour Matters

Pallet racking is a highly efficient structure. It carries very large loads on relatively slender cold-rolled sections, and it does so by relying on every component behaving as designed. An upright that has been struck no longer has the section properties the designer assumed. The load has not changed, but the capacity has, and the failure mode of a damaged upright is buckling — which is sudden, not gradual.

That is why the industry standards treat impact as a trigger event rather than a cosmetic issue. BS EN 15635, the European standard for the use and maintenance of static steel storage equipment, requires that any damage identified is assessed by a competent person and that equipment exceeding the published tolerances is offloaded immediately.

Step 1 — Stop Loading and Keep People Clear

The single most dangerous response to racking damage is to carry on. Do not place another pallet in the affected bay, and do not use the bay above or below as a workaround. Move people and traffic away from the aisle while you assess. Any collapse takes the beam contents with it, so the exclusion zone should cover the full footprint of the run, not just the visibly damaged frame.

Step 2 — Unload and Isolate the Affected Bay

Remove stock from the damaged bay, working from the top down, and remove it with a machine rather than by hand wherever possible. Then physically isolate the bay: barrier tape, cones or a barrier across the aisle face, plus a clearly worded notice stating the bay is out of service and must not be loaded. Tell the shift, not just the supervisor — verbal handover between shifts is where isolations most often get lost.

Step 3 — Report It Internally

Report the damage to the person your site has appointed as Person Responsible for Racking Safety (PRRS). BS EN 15635 expects a named individual to hold this role, to maintain the damage register and to control the process for taking equipment out of and back into service. Record the date, time, aisle, run and bay reference, the type of equipment involved and the circumstances. That record is what your insurer and, if it ever comes to it, an inspector will ask for.

Under RIDDOR 2013, a full or partial collapse of racking used to store goods is a reportable dangerous occurrence, and any resulting injury above the reporting threshold is separately reportable. Damage found without collapse or injury is an internal record only.

Step 4 — Photograph and Measure Before Anything Is Touched

Photograph the damage from the aisle, from the rear, and close up at the base plate and any deformed section. Include a tape or rule in the frame so scale is obvious. Photographs are also what allows a repair specialist to quote accurately without an initial site visit, which shortens the whole process.

Measurement follows the SEMA tolerances used throughout our pallet racking repairs assessments:

• Upright frontal bend (cross-aisle): 3 mm maximum, measured over a 1 metre gauge length
• Upright lateral bend (down-aisle): 5 mm maximum, measured over a 1 metre gauge length
• Bracing members in either plane: 10 mm maximum over a 1 metre gauge length
• Beam deflection under working load: span divided by 200 — so a 2,700 mm beam must not deflect more than 13.5 mm
• Beam residual deformation once unloaded: span divided by 1000

These are not opinions about what looks bad. They are the pass/fail criteria a competent inspector applies, and anything outside them means the component is out of service until it is replaced.

Step 5 — Do Not Attempt a Makeshift Repair

Welding a plate over a buckled upright, jacking a frame back into line, or swapping in a beam from a different manufacturer are all common and all unacceptable. Cold-working damaged steel changes its properties in ways nobody on site can quantify. Mixing manufacturers matters because connector geometry, clip engagement and hole pitch differ between Dexion, Mecalux, Redirack, Link 51, Stow, Bito, PSS, Esnova and Apex systems — a connector that only partly engages will pull out under load long before the beam itself fails.

The correct repair is like-for-like replacement of the damaged component with the correct section and grade, or an engineered repair system approved for that profile, installed by a SEIRS-registered installer.

Step 6 — Bring in a SEMA-Aligned Engineer

A competent racking engineer will assess not only the struck component but the load path around it: the frame bracing, the beam connectors either side, the base plate, the floor fixings and the plumb of the run. It is common for the visible dent to be the least important finding. Our emergency racking repair process follows exactly this sequence, and every repair is quoted as a fixed price against the components actually needed.

Step 7 — Return to Service Properly

A bay should only come back into use once the replacement components are installed to the manufacturer's specification, the floor fixings are torqued and verified, the frame is re-plumbed within tolerance, the load notice still reflects the configuration, and the damage register is updated to close out the entry. Ask for a written completion record. That document is what closes the loop for PUWER Regulation 5 maintenance evidence.

The Legal Framework in Plain English

Three instruments do most of the work in the UK:

• PUWER 1998 — racking is work equipment. Regulation 5 requires it to be maintained in efficient working order and good repair. Regulation 6 requires inspection where safety depends on installation conditions or deterioration. Regulation 8 requires that people using it have adequate information, and Regulation 9 requires adequate training.
• HSE HSG76, Warehousing and storage: a guide to health and safety — the HSE's practical guidance, covering both racking and shelving, including damage, inspection regimes and the case for a named responsible person.
• BS EN 15635 — the standard for the use and maintenance of storage equipment, which sets out the inspection hierarchy, the damage classification and the competent-person expectation.

None of these require perfection. What they require is that damage is found, assessed against a defined standard, controlled while it exists, and put right.

Preventing the Next One

Most warehouses see the same handful of bays damaged repeatedly, usually at aisle ends, near pick faces and at points where drivers turn under time pressure. Column guards, aisle-end barriers, clear floor marking, sensible aisle widths for the trucks actually in use, and refresher training address the majority of it. Rack protection products are available through our parent company at rackstor.co.uk.

Combining that with a scheduled inspection and repair cycle is far cheaper than reactive work. Our racking maintenance programme exists for exactly that reason, and the underlying causes are covered in more detail in racking damage — common causes and how to prevent them.
