Vehicle strikes kill and seriously injure people in warehouses every year. The HSE records show that over the last 5 years, being struck by a moving vehicle has been the second biggest cause of fatal injury in the workplace after falls from height. In pharmaceutical warehouses, the risk to life is the same as anywhere else. But the consequences of a single incident don't stop at the immediate harm.
If you manage health and safety on a pharmaceutical site, you already know the weight of that responsibility. Your warehouse operates under a layer of compliance obligations that many other sectors don't carry, and when something goes wrong, the fallout extends well beyond the accident report.
This article covers the specific safety challenges that make pharmaceutical warehouses a challenge to manage, and what practical controls can help you address them, starting with keeping your people safe.

What Makes a Pharmaceutical Warehouse Different?
Most warehouses share the same core risks: pedestrians and vehicles sharing space, racking under load, loading bays, shift changes. Pharmaceutical warehouses carry all of those, but the operating environment adds layers of complexity that standard guidance doesn't always account for.
A few things set pharma sites apart:
- Controlled environments. Temperature-controlled storage, clean rooms, and restricted access zones create physical boundaries that concentrate pedestrian and vehicle movement at specific chokepoints — typically threshold areas where staff pass between zones.
- High-value, trace-critical stock. Pharmaceutical products are often subject to strict batch traceability requirements. A vehicle strike that damages racking or product doesn't just create a repair job — it can trigger a batch investigation and potential product quarantine.
- 24-hour operations. Continuous manufacturing and fulfilment mean the warehouse usually never stops. Shift changes (when pedestrian and vehicle movements peak simultaneously) are consistently among the highest-risk periods on any site.
Where Are the Highest-Risk Zones?
Every site is different, but pharmaceutical warehouses tend to share a handful of areas where incidents are most likely to occur:
- Controlled environment thresholds. The entry and exit points to cold stores and clean zones see constant foot traffic. People moving in and out of these areas often have limited sightlines and may be carrying items or wearing PPE that restricts their peripheral vision.
- Loading and dispatch areas. The intersection of external delivery vehicles, internal forklifts, and warehouse staff creates one of the most complex traffic management challenges on any site. Under HSG136, employers are required to assess and manage the risks at these interfaces, but many sites still rely on painted lines and procedural controls rather than physical segregation.
- Racking aisles. In pharmaceutical warehouses, racking often holds high-density, high-value stock in narrow aisles with limited turning space. Rack end impacts are one of the most common forms of vehicle damage, and without adequate rack end protection, a single impact can compromise the structural integrity of an entire bay.
- Shift handover points. As HSE guidance on workplace transport makes clear, risk assessments must specifically account for periods when pedestrian and vehicle numbers change, such as shift changes. On a 24-hour pharmaceutical site, this can happen multiple times in a single day.
Why Physical Segregation Fails in Pharma Environments
The default response to pedestrian segregation in many warehouses is painted floor lines. It's familiar, low-cost, and looks effective on a risk assessment.
In pharmaceutical warehouses, it falls short for reasons that go beyond normal wear and tear:
- Floor markings in cold stores and temperature-controlled environments are subject to expansion, contraction, and moisture, all of which accelerate fading and lifting.
- Painted lines offer no physical protection. When a forklift drifts, there is nothing to stop it.
- Repainted lines require downtime, disruption, and in some cases temporary closure of controlled zones.
- Steel barriers corrode in humidity-rich environments, shed rust particles, and create contamination risks in areas where surface cleanliness matters.
The Workplace (Health, Safety and Welfare) Regulations 1992 require employers to ensure traffic routes are organised so that pedestrians and vehicles can move without endangering each other. In practice, that means physical controls, not procedural ones, wherever reasonably practicable.
"Physical segregation is the most reliable form of pedestrian protection. Relying on painted lines alone is not sufficient where vehicles operate at speed or where sightlines are limited." - HSE guidance, Workplace Transport Safety (HSG136)
What Happens After a Vehicle Strike in a Pharmaceutical Facility?
The immediate priority after any vehicle incident is the welfare of the people involved. That is always first.
But on a pharmaceutical site, once the immediate response is under way, the operational impact begins to unfold. The incident triggers a formal investigation. If stock was involved, a batch review follows. If the incident occurred in or near a controlled environment, that zone may need to be taken out of operation while its integrity is assessed.
Under RIDDOR (the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013), certain workplace injuries must be reported to HSE. A serious injury or fatality resulting from a vehicle strike is a reportable incident, and once HSE is involved, the site's traffic management arrangements, risk assessments, and physical controls will all come under scrutiny.
For pharmaceutical operations with continuous batch production, an unplanned line stoppage can mean more than lost time. It can mean product that cannot be released, investigation reports that delay future batches, and questions from your quality team that go well beyond the safety department.
What Does Good Look Like?
The most effective pharmaceutical warehouse safety setups share a common approach: they treat physical segregation as infrastructure, not as an afterthought.
That means:
- Polymer safety barriers at racking ends, along pedestrian routes, and at the boundaries of controlled environments. Unlike steel, polymer barriers flex on impact rather than transferring force, they protect the floor, the racking, and the people working nearby. They're also non-corrosive and easy to clean, which matters in environments where surface hygiene is part of your compliance picture.
- LED projected floor markings at pedestrian crossing points and controlled environment thresholds. Projected markings don't fade, don't peel, and don't require scheduled maintenance. In cold stores and clean zones, where traditional floor tape fails quickly, they're a practical alternative that maintains visibility regardless of conditions.
- Clearly defined traffic management plans that reflect the layout of the site , including controlled environment entry and exit points, racking aisle access, and loading bay interfaces.
- Regular review of risk assessments in line with PUWER obligations, particularly when the site layout changes or new equipment is introduced.
Take a look at how polymer safety barriers and LED projected floor markings are used to create physical segregation in complex warehouse environments.
The Practical Steps Every Pharma EHS Manager Should Take
If you're reviewing your pharmaceutical warehouse safety arrangements, these are the areas worth starting with:
- Walk your highest-risk zones (controlled environment thresholds, loading areas, and racking aisles) and note where physical segregation is absent or relies solely on painted markings.
- Review your PUWER assessments for any lift trucks or pallet movers operating in the warehouse and check whether the segregation controls documented in those assessments are actually in place.
- Consider shift-change periods specifically. If pedestrian and vehicle movements coincide, that's a risk that needs a physical control, not just a procedure.
- Check your racking end protection. Rack end barriers are one of the most consistently absent controls we see on site visits, and one of the most straightforward to address.
