Facing a variety of operational pressures, from extended transit routes avoiding the Red Sea to unpredictable vessel blank sailings, it’s unsurprising that many warehousing businesses are pivoting from the efficiency-led ‘just-in-time’ model to the resilience-driven ‘just-in-case’ model.

However, suddenly adopting an inventory-heavy storage approach can place significant strain on internal aspects of warehousing operations, including the warehouse workers themselves. The more crowded a warehouse becomes and the more the layout shifts to accommodate additional stock, the greater the ergonomic risk for staff.

In this guide, we explore the potential injury risk of just-in-case storage in warehouses, the role and challenges of warehouse manual handling risk assessment, and what operators can do to protect their workers and their bottom line.

How do overcrowded warehouses accelerate injury rates?

When stock begins to pile up at warehouses, whether part of a strategy or not, the risk of worker injuries can increase due to several reasons.

Safe working zone shrinkage

In a spacious warehouse, there is more room for workers to adopt optimal postures for carrying out their tasks. For example, during manual handling, you can get closer to the load and lift using your legs, with weight distributed equally across the body.

When a warehouse becomes more crowded, safe working zones are compressed. Aisles become narrower and staging areas shrink. These conditions create scenarios in which workers may be forced to navigate obstructing objects to manage a load.

Instead of healthy neutral postures, they’re forced to rely on twisting and bending, placing excessive strain on specific part of the body. Usually, the lower back is placed under the most pressure, but, depending on the postures involved, it can lead to a host of upper limb disorders as well.

Extreme vertical storage

Maximising vertical space is key to freeing up work zones in warehouses, but this can easily become its own problem. Repeated reaching to handle loads above shoulder height can place stress on the neck and rotator cuffs.

Without careful management, this can lead to neck strain, shoulder impingement or RSIs.

Rapid layout adjustments

Just-in-case storage can cause layout challenges as it is, but with shipping schedules being so unpredictable at the moment, layouts often have to shift on the fly to accommodate sudden influxes of inventory.

Depending on the type and scale of inventory, this can be a grueling task, one that must be repeated time and time again to continuously maximise space.

Furthermore, staff are constantly required to adapt to a changing environment, resulting in improvised workflows and riskier approaches to tasks. For example, mechanical aids, such as fork lifts or scissor lifts, could become obstructed by inventory, meaning some of the most physically demanding and unsafe jobs may be attempted manually.

Temporary warehouse workers brought in to support the in‑house team are particularly at risk, as their limited familiarity with the site makes it harder to navigate these constantly shifting layouts safely. We explore this in more depth in our companion article on the importance of risk assessments for temporary warehouse workers. 

Productivity pressure

More inventory often means more work for warehouse staff, and the current lack of shipping predictability means that it’s incredibly hard to plan ahead and increase headcount to handle more intensive workloads.

To manage just-in-case volumes and keep loading bays operational, warehouse staff may be forced to work longer, faster, and harder – and the lack of recovery time between heavy lifts leads to exhaustion.

Tiredness impacts focus and decision-making, which makes a warehouse a significantly more dangerous environment. What’s more, when muscles aren’t given the time required to recover, disrepair can accumulate over time, in some cases leading to long-term musculoskeletal disorders that may result in long-term absences.

In these high pressure scenarios, even teams with excellent manual handling knowledge may fall back on bad habits in order to take risky “shortcuts”.

Controlling costs in just-in-case warehousing – ergonomics is essential

When margins are squeezed by soaring business rates and unpredictable supply lines, protecting your bottom line means protecting your workforce with proactive warehouse ergonomics.

A single severe manual handling injury or a spike in Work-Related Upper Limb Disorders (WRULDs) can lead to long-term absences, costly reliance on temporary agency staff, and devastating insurance premium hikes.

Warehouse manual handling risk assessments are key, but…

Traditional methods aren’t designed for the intensity of the current warehousing and logistics landscape. 

In a standard operational environment, a warehouse manual handling risk assessment is a static, periodic task. An assessor watches a worker, fills out a paper checklist, and files a report.

But when your facility is operating under a just-in-case model, you cannot effectively manage risk because:

• The environment is fluid: A risk assessment completed on Monday is obsolete by Wednesday because a new shipment arrived and narrowed the aisle.
• Time is non-existent: Safety managers don’t have the hours to sit and manually log dozens of different lifting tasks while loading bays are backing up.
• Subjectivity creeps in: Under productivity pressure, it’s incredibly difficult to accurately visually gauge the exact physical strain on a worker’s spine or shoulders.

To protect your margins, you need a more agile approach to manual handling assessment.

Healthy Working RiskAI – A practical solution for injury prevention in warehousing

When warehouse layouts are mutating on a weekly basis to accommodate huge amounts of stock, traditional, paper-based ergonomic assessments rarely keep up. Transitioning to an automated warehouse risk assessment model is therefore crucial.

With Healthy Working RiskAI, warehouse managers can capture and assess movement in seconds using a simple smartphone app. There’s no heavy equipment or disruption to the shifting warehouse floor.

The app instantly feeds data into our Risk Analytics Dashboard, turning video footage into real-time performance scores and flagging high-risk tasks. Whether it’s a worker overreaching in a newly narrowed aisle or stooping too low under a temporary rack, RiskAI centralises this data across your teams and locations. 

It removes the guesswork, giving you a clear, actionable view of physical risk at the task level so you can make data-driven safety decisions before an injury occurs.

We’re currently offering a one-month free trial of Healthy Working RiskAI, so you can test it with your workforce and see how it impacts your safety strategy before committing to a solution. 

Claim your 30-day free trial to:

• Identify hidden ergonomic risks before they become costly injuries.
• Keep your loading bays moving without burning out your workforce.
• Protect your bottom line from steep insurance hikes and absence costs.
