What a single forklift impact actually costs your warehouse

It starts with a knock. It ends with a six-figure problem. Here's how a single unreported impact can quietly unravel your operation.

‍

It's 2:40pm on a Wednesday. Aisle seven, bay twelve. A forklift driver is backing out with an empty pallet, turns a fraction too tight, and clips the base of a rack upright.

It's not a dramatic collision. There's no crash, no alarm, no one running over to check. Just a dull thud, a slight vibration through the frame, and the driver glancing in his mirror before moving on to the next pick.

He knows it happened. But it didn't feel like much. The rack looks fine from where he's sitting. There's nothing on the floor. He's behind on his picks and the shift supervisor is already asking where that last pallet is.

So he keeps going.

And right there, in that completely ordinary, completely human moment, the clock starts ticking.

‍

Hour one: the damage nobody sees

From the outside, the upright looks mostly fine. Maybe a slight dent at the base, barely visible unless you're crouching down and looking for it. The rack is still standing. The load above is still in place. Nothing has fallen.

But inside the steel, the geometry has changed. That impact shifted the upright just enough to reduce its load-bearing capacity. The manufacturer designed it to carry a specific load at a specific tolerance. A dent of just a few millimetres can compromise that.

The thing is, nobody's crouching down and looking for it. The afternoon shift carries on. The evening shift comes in, loads up the same aisle, and never notices. The next morning, fresh pallets go up on the levels above.

The rack holds. For now.

Week two: the inspection that misses it

The monthly visual check rolls around. A supervisor walks the floor with a tablet, scanning for obvious damage: leaning frames, missing safety clips, debris in the aisles.

She walks past aisle seven, bay twelve. From standing height, the base of the upright isn't clearly visible, there's a pallet on the ground level partially blocking the view. The dent is at the back of the upright, facing the adjacent bay. She'd have to walk around, crouch down, and look behind the pallet to see it.

She doesn't. Not because she's careless, because she has 14 aisles to cover in 90 minutes and nothing about bay twelve looks unusual from where she's standing.

The inspection is logged as complete. No issues found in aisle seven.

‍

Month two: the damage gets company

Four weeks later, another forklift catches the same upright, this time a glancing blow from the opposite direction. The driver barely registers it. Two knocks, same spot, six weeks apart.

The upright now has visible deflection. If you looked carefully, you'd see it leaning slightly out of plumb. But "slightly" at ground level is hard to spot when you're walking at pace. And at height, six, eight, ten metres up, that slight lean is amplified. The load above is no longer perfectly centred over the upright. Gravity is doing what gravity does.

Meanwhile, on level five of that same bay, a pallet has been sitting for three weeks. The shrinkwrap was already loose when it came in from the supplier. Over time, the load has shifted slightly. One corner of the carton is now overhanging the beam by a couple of inches.

Nobody can see this from the floor. It's twelve metres up.

‍

Month three: the incident

A Tuesday morning. A different driver is putting a pallet away on level three of bay twelve. The forklift mast extends, the load goes up, and as the forks tilt forward to place the pallet, the mast brushes the weakened upright.

It's the third impact on the same spot. This time, the upright buckles.

The failure isn't instant, it's progressive. The frame shifts, the beam on level five drops at one end, and the pallet with the loose shrinkwrap slides. Three cartons fall twelve metres to the floor. One clips the forklift cage on the way down. The driver is shaken but unhurt.

The aisle is shut down immediately and the warehouse manager is called. Then the H&S lead. Then the site director.

And now the real cost begins.

‍

The cost that doesn't fit on a spreadsheet

The obvious costs come first. The damaged racking needs to be assessed by a structural engineer before anyone can go near it. That takes two days to arrange. In the meantime, aisle seven is cordoned off. That's roughly 200 pallet positions out of action.

The engineer's assessment: two bays need full upright replacement. Estimated repair cost: £8,000–12,000 including parts, labour, and re-commissioning. Lead time for the steel: three weeks.

But the repair cost is the easy part. Here's what comes after.

Lost inventory. The three cartons that fell were consumer electronics. Total write-off value: £14,000. The product is unsalvageable. The insurance claim takes weeks to process and doesn't cover the full retail margin.

Downtime. Aisle seven is partially closed for three and a half weeks while repairs are completed. During that time, stock that would normally go into those bays has to be diverted. The warehouse is already running at 92% capacity. The knock-on effect on putaway times and pick efficiency is immediate.

Investigation time. The H&S team spends the equivalent of four full working days investigating the incident, documenting it, interviewing staff, and reviewing CCTV. The warehouse manager and shift supervisors are pulled into meetings. The operations director wants a full report.

Compliance exposure. The site's next formal racking inspection, the annual one carried out by an external specialist, is brought forward. The inspector finds two more damaged uprights in adjacent aisles that had also gone unreported. The inspection report recommends a broader review of the reporting culture on site.

Insurance consequences. The insurer is notified. Premium renewal is four months away. The incident is now on the record. The broker advises to expect an uplift.

Team morale. The driver involved in the final impact is off work for a week with stress. Two other drivers in the same shift request reassignment to a different area of the warehouse. 

Total estimated cost of a single forklift impact that went unreported for three months? Conservative estimate: £85,000–120,000. And that's without a serious injury. If someone had been standing in the drop zone, the numbers, and the consequences, would be in a completely different category.

The pattern, not the exception

The details vary, but the pattern is the same in warehouses everywhere.

A minor impact goes unreported, a scheduled inspection doesn't catch it = the damage sits there for weeks or months. A second event triggers a failure. And suddenly a £50 repair has become a six-figure problem.

The industry knows this. Racking collapses are consistently among the most costly and dangerous warehouse incidents. Studies suggest that forklift impacts account for the vast majority of rack failures. And underreporting of minor damage is widely acknowledged as one of the biggest challenges in warehouse safety management.

The question is not: is this happening in my warehouse?
But: Would you know about it if it was?

‍

What would change if you could see everything, every day?

Imagine a different version of that Wednesday afternoon in aisle seven.

The forklift clips the upright at 2:40pm. By 9pm the same day, an autonomous robot completes its routine scan of the warehouse. Its cameras capture every rack face, at every level, in every aisle, including the base of that upright in bay twelve.

Computer vision AI flags the new dent. It's logged with the exact location, timestamp, and an image. The next morning, the ops manager sees it in their dashboard. A maintenance ticket is raised. The upright is assessed, the damage is repaired before it compounds, and the total cost is a few hundred pounds and zero downtime.

That's the difference between reactive and continuous.

This is what Storage Health does

At Dexory, we built Storage Health to close exactly this gap. It's a feature within DexoryView Integrity that uses computer vision AI to help you detect damage, hazards, and hygiene issues across your warehouse, at every height, in every aisle, during every robot scan.

It flags potential cases of damaged racking, pallet defects, tipping items, hanging shrinkwrap, item defects, and empty pallets. Every detection is logged with location, date, type, and image, giving your team a digital audit trail and the ability to triage issues remotely before sending someone to investigate.

‍

‍

It doesn't replace your safety inspections or your team's judgement. It gives them a continuous, full-height layer of visibility that manual checks alone can't provide.

Storage Health recently won Best New Innovation at the 2026 MHI Innovation Awards at MODEX in Atlanta, recognition that the industry is ready for a fundamentally different approach to warehouse condition monitoring.
