Something has gone wrong on your site. Maybe a forklift almost struck a pedestrian. Maybe the near-miss was serious enough to stop the shift. And no doubt, an internal investigation is underway.
Whatever happened, there's always pressure to fix things fast. But rushing into reactive fixes without understanding the root cause is a common and costly mistake we see during site assessments.
We know the weight of that moment. The urgency, the scrutiny from above, the worry about what comes next. This article will walk you through how to move from crisis response to genuine, lasting safety improvement, step by step.

After a serious incident, the instinct is to do something visible. Repaint the floor lines. Order a batch of barriers. Put up new signage.
But these are surface-level responses to what is almost always a systemic failure.
The HSE sees this pattern repeatedly. In October 2025, HSE Deputy Director for Technical Support and Engagement John Rowe noted that workplace transport deaths follow predictable patterns, and that the failures behind them are rarely complex. The same basic gaps appear again and again: poor segregation, inadequate risk assessments, and a lack of physical separation between people and vehicles.
Vehicle strikes are not freak accidents. They are the predictable result of controls that were either missing, damaged, or never properly implemented.
If your post-incident response only addresses the visible symptom – the painted line that was faded, the barrier that was missing – you have not addressed why those controls were absent in the first place.
The first two days after a serious incident set the tone for everything that follows. Get them right and you build a foundation for real improvement. Get them wrong and you are playing catch-up for months.
Your immediate priorities are legal compliance, scene preservation, and communication.
Under RIDDOR 2013, certain incidents must be reported to the HSE without delay. Deaths, specified injuries (fractures, amputations, crush injuries), and dangerous occurrences require notification by the quickest practicable means, with a written report within 10 days. Injuries causing more than seven consecutive days off work must be reported within 15 days. Failing to report a RIDDOR-qualifying incident is a criminal offence.
Preserve the scene. Do not move equipment, clean up, or alter the area until you have fully documented it. Photographs, measurements, witness accounts, CCTV footage: gather everything while memories are fresh and evidence is intact.
Communicate clearly with your team. People will be shaken. Rumours spread fast. A brief, honest update acknowledging what happened and outlining next steps goes further than silence ever will.
A good investigation does not just ask what happened. It asks why it was possible for it to happen.
This means going beyond the immediate cause (the forklift was going too fast, the pedestrian stepped into the wrong area) and examining the underlying failures in your system.
Start by mapping the sequence of events. What was supposed to happen? What actually happened? Where did the two diverge?
Then dig into the contributing factors:
• Were risk assessments up to date and reflective of how the site actually operates?
• Were physical controls – barriers, gates, walkway markings – in place and in good condition?
• Were traffic routes clearly defined and properly segregated?
• Had workers been consulted on safety decisions, or just informed after the fact?
• Were there previous near-misses that should have flagged the risk earlier?
The Workplace (Health, Safety and Welfare) Regulations 1992 require traffic routes to be organised so that pedestrians and vehicles can circulate safely. If your investigation reveals that routes were poorly defined, barriers were damaged or missing, or that pedestrians and vehicles were routinely sharing space, you have identified a systemic gap – not just an individual error.
Under the Health and Safety at Work etc. Act 1974, employers have a general duty to ensure, so far as is reasonably practicable, the health, safety and welfare of all employees. The courts have made clear that this duty extends to providing and maintaining safe systems of work, not just reacting when something goes wrong.
Effective corrective actions follow the hierarchy of controls. The most reliable fixes are those that remove or reduce the hazard at source, rather than relying on people to behave differently.
For warehouse and factory environments, that hierarchy typically looks like this:
Physical separation is the most effective control. Dedicated pedestrian walkways protected by polymer safety barriers. Segregated vehicle routes. Self-closing pedestrian gates at crossing points. These are design-based solutions that do not depend on individual behaviour.
If you are mapping out where new barriers need to go, our zone-by-zone placement guide for UK warehouses breaks down the decision by area so you are not second-guessing the layout.
Engineered controls add further layers. LED projected floor markings that activate when pedestrians approach a crossing point. One-way traffic systems. Speed-limiting devices on FLTs. These work even when attention lapses.
Administrative controls come last. Updated risk assessments. Revised traffic management plans. Refreshed training programmes. Clearly displayed signage and floor markings. These matter, but they are the least reliable layer when used in isolation. Painted lines fade. Signs get ignored. People take shortcuts when they are under pressure.
If your corrective action plan relies entirely on retraining staff and adding signage, you are repeating the pattern that led to the incident in the first place.
Recent prosecutions reinforce this. In June 2025, JMP Wilcox & Co Limited was fined £300,000 after a worker suffered serious injuries from being struck by a vehicle. The HSE found that the company had failed to put suitable control measures in place to separate people from moving vehicles.
The pattern across incidents is usually consistent: the failures were basic, the controls were well-established, and the incidents were preventable.
Safety improvements only stick when the people on the ground trust the process. After a serious incident, that trust is fragile.
Start by involving your workforce in the investigation and the solution. ISO 45001 places heavy emphasis on worker consultation, and for good reason. The people who operate forklifts, walk the aisles, and load the bays every day understand the risks better than anyone reviewing a floor plan from an office.
Share the findings of your investigation openly. Explain what went wrong, what is changing, and why. If new barriers are being installed, explain where they are going and how they protect the team. If traffic routes are being redesigned, walk the new layout with operators before it goes live.
Make the improvements visible. When workers can physically see new barriers in place, new LED walkway markings activated, new gates installed, it sends a clear signal that the business is taking action – not just producing paperwork.
And follow through. The worst thing you can do after an incident is announce a comprehensive safety review and then let it quietly stall. If you have committed to a corrective action plan, deliver it on schedule. Your team is watching.
There is no shame in recognising that your internal team needs support. In fact, the HSE expects organisations to seek competent assistance where they lack in-house expertise.
An independent site assessment brings a fresh pair of eyes. It maps traffic flows as they happen, not as they appear on a plan drawn up three years ago. It identifies gaps that internal familiarity can make invisible: the blind corner everyone has got used to, the crossing point where pedestrians and FLTs routinely share space, the damaged barrier that has been on the maintenance list for six months.
At Clarity, our site assessments follow the same framework HSE inspectors use. We map your pedestrian and vehicle routes, assess your existing barriers against PAS 13:2017 standards, review your documentation, and identify the compliance gaps that need addressing – ranked by risk priority.
The output is a clear, costed plan that you can take to your board, your insurer, or your HSE inspector with confidence.
