Preventing Forklift Impact: Practical Tips

Every warehouse manager knows racking damage costs money. Fewer track where it happens, and that is the gap between reacting to damage and reducing it. Impact damage is not evenly distributed — it concentrates in a handful of positions, caused by a handful of repeated manoeuvres. Once you can see that pattern, prevention becomes cheap.

Start by Finding the Pattern

Before buying a single guard, record damage by location for a few months: aisle, run, bay, component, date, shift. Almost every site discovers the same thing — a small number of positions account for most incidents, usually aisle ends, bays near dispatch, and the runs closest to the busiest pick faces.

That record does three things. It targets spending on the frames that are actually being hit. It shows whether an intervention worked. And it satisfies the record-keeping expectations that sit behind PUWER 1998 Regulation 5 and BS EN 15635 anyway.

Physical Protection Where It Is Needed

Column guards fitted to the lower section of vulnerable uprights take low-level impact into a sacrificial component instead of the frame. They are most effective on the legs either side of bay entries in aisles with heavy traffic.

Aisle-end barriers and end-of-rack protectors address the position that takes the most abuse on almost every site: the frame at the corner where trucks turn. These protect the frame that, if it fails, takes the longest run of racking with it.

Guide rails in narrow aisles keep trucks centred and away from uprights entirely, and are usually the best value intervention in VNA or near-VNA operations.

Rear pallet stops and back-to-back ties stop pallets being pushed through onto the components in the adjacent aisle — a damage source that always shows up in the wrong place on the register.

Protection products are available through our parent company at rackstor.co.uk. One point worth stating plainly: a struck guard is not a non-event. It is a recorded impact and it should prompt a check of the frame behind it.

Layout and Clearance

A lot of damage traced to "driver error" is actually a clearance problem. Aisle widths should be based on the trucks currently in use, the pallets currently handled and the manoeuvres actually required — not on the operation the warehouse had when it was designed. Sites that switch truck types, move to a larger pallet footprint or add a shift often see damage rates rise at exactly the points where effective clearance shrank.

Practical checks: is there room to approach the bay square, or are drivers turning into the last part of the entry? Are pedestrian routes segregated so drivers are not manoeuvring around people? Is floor marking still visible? Is lighting adequate at the aisle ends? Are the frames that get hit most in the darkest part of the building?

Driver Behaviour and Training

PUWER 1998 Regulation 9 requires adequate training for anyone using work equipment, and Regulation 8 requires adequate information and instructions. In practice that means more than an initial licence.

What reduces impacts: refresher training focused on the manoeuvres your site actually requires rather than generic content; specific coaching for the operations where the damage register shows clustering; briefing new and agency staff on the site's high-risk positions before they start; and making sure drivers understand what a damaged upright means structurally — most people who have seen a rack collapse video drive differently afterwards.

What does not reduce impacts: blanket disciplinary responses. They reduce reporting, not incidents.

Reporting Culture Is the Highest-Value Control

The most dangerous damage on any site is damage nobody reported, because it stays fully loaded. A reporting system works when three things are true: reporting takes seconds, there is no penalty for honest reports, and drivers can see that reports lead to repairs.

Sites that get this right see reported damage go up initially and total damage go down over time. Sites that punish reports see the opposite of both, with the difference sitting in the structure.

Prompt Repair Is Prevention

Damage left in service gets worse. A frame carrying a load path it was not designed for redistributes force to its neighbours, and the same bay is more likely to be struck again because there is now less clearance and a visible deformation drivers steer around at the last moment.

Under the SEMA classification, amber damage — out of tolerance but not at immediate risk of failure — must be offloaded and repaired within four weeks; red damage is offloaded and isolated immediately. Keeping to those timescales is what stops a cheap component swap becoming a run replacement. The measurement criteria are the standard tolerances: 3 mm frontal and 5 mm lateral upright deflection over a 1 metre gauge length, 10 mm on bracing, span/200 beam deflection under load and span/1000 residual.

Inspection as an Early-Warning System

A weekly documented visual check by the nominated Person Responsible for Racking Safety catches damage while it is still amber. An expert inspection at intervals of no more than 12 months, as expected by BS EN 15635 and reflected in HSE guidance HSG76, catches what daily familiarity hides. Both are cheap compared with a single emergency offload of a fully loaded run.

That combination — protection where damage clusters, layout that matches the trucks in use, targeted training, honest reporting and scheduled inspection — is what our racking maintenance programme is built to deliver.

What to Do When Prevention Fails

It will occasionally, and the response matters. Follow the sequence in what to do if your racking is damaged: stop loading, offload safely, isolate visibly, record, and get a competent assessment. For serious damage see emergency racking repair, and for the underlying causes across all damage types see racking damage — common causes and how to prevent them.
