Think for a moment about your personal definition of productivity. Words like “effectiveness” and “output” and “production” likely come to mind.
But what we often forget in material handling is that productivity doesn’t have to mean harder work. In fact, in manufacturing operations and distribution facilities, higher productivity often means less demanding physical work, employee touches, and interactions between product and personnel.
What do we mean by this?
The answer lies in ergonomics, the science of designing the job to fit the worker instead of physically forcing the worker’s body to fit the job. According to the Occupational Health & Safety Administration, ergonomics helps lessen muscle fatigue, increases productivity, and reduces the number and severity of work-related musculoskeletal disorders (MSDs).
Let’s take a look at the relationship between ergonomics and productivity in the distribution center:
In the distribution center, workplace injuries aren’t just detrimental to employee health and safety; they can also have a significant impact on productivity. With workers sidelined and unable to work, companies face serious productivity losses – not to mention costly worker compensation insurance premiums.
In addition to serious injuries such as falls, slips, and trips, warehouse workers run the risk of developing MSDs, including muscle strains, lower back injuries, carpal tunnel syndrome, tendinitis, and more. U.S. Bureau of Labor Statistics data, in fact, shows MSDs are twice as common in the warehousing and distribution sector as they are in other private-sector industries.
Enter workplace ergonomics. Ergonomics is not a feel-good factor, but instead the linchpin in designing work processes and workplaces. Ergonomics not only contributes to the well-being and relief of the staff but also brings measurable and distinct advances in productivity.
Here are a handful of actionable tips for distribution centers to drive productivity gains with ergonomics:
Aside from making ergonomic adjustments to workstations while workers are standing in place, it’s also critical to factor in how much a worker needs to move around the warehouse in order to perform industrial tasks.
Let’s take order picking, for example. In a distribution or warehousing operation, the most common working concept is “person-to-goods” order picking, which means that order pickers move to storage locations, often pushing or pulling carts and reading orders off paper. These pickers spend significant amounts of time (up to 60%) walking between storage, so reducing that time-spend is an excellent idea.
Automated solutions (automated storage and retrieval, robotic picking systems, etc.) and manual systems (carton and gravity flow systems, pallet flow systems, etc.) can help to make accuracy and productivity improvements in these cases.
But a good ergonomics program will also help facilities design workstations so that everything is within reach of the operator (to the extent possible). Oftentimes, ergonomic solutions are the result of implementing the automated or manual systems listed above. Carton and gravity flow systems, for instance, install easily into existing pallet racks, helping to create ergonomic workstations ideal for picking, assembly, or lineside storage.
Ergonomics may not have been a prime plant design consideration in the past, but today’s consumer-driven marketplace demands that distribution facilities operate as efficiently and productively as possible.
Proper space utilization is of particular importance during the holiday season, the busiest time of year for retailers. As stated in a previous UNEX blog post, “distribution operations must be in high-performance mode and ready to handle peak volumes.”
By understanding the way that shelves and space are being utilized, UNEX notes, facilities can determine how best to maximize warehouse efficiency: “The placement of shelves and containers, along with the traffic patterns and total design of the building, ultimately affects the ability for [facilities] to utilize any space available.”
Beyond product storage, an in-depth look at space utilization can also help warehouses design the workstation most efficiently for workers. The idea is to minimize reach, reduce twisting, and avoid long periods of standing in one position so that workers won’t need to take steps to reach product or materials.
In material handling and distribution, improving productivity doesn’t have to mean pushing workers to work harder. Instead, focusing on ergonomics—designing tasks and workstations to fit the worker—can enhance productivity while reducing physical strain and injury risk. UNEX offers a range of solutions that address key ergonomic challenges in distribution centers, helping to decrease injury risks, reduce travel time, and optimize space utilization.
SpanTrack Lane has full-width roller lanes that provide smooth SKU flow, which reduces picker fatigue and repetitive stress. By keeping products accessible and ensuring efficient flow, SpanTrack minimizes the need for excessive movement and awkward postures, helping to create safer work environments while boosting productivity.
This solution not only improves throughput but also reduces the physical toll on workers, allowing them to access products more quickly without the need for extensive walking or bending.
Tilted pick shelves can be customized to meet the specific needs of your operation, ensuring that products are always accessible and within the ergonomic "safe zone" for employees. This increases not only productivity but also employee satisfaction by making tasks physically easier.
In the distribution center, ergonomics isn’t just a good idea for worker health and longevity: It’s also critical to driving productivity in the warehouse. As noted above, a good ergonomics program can decrease the risk of injury, reduce travel time for workers, and optimize space – driving significant improvements to the bottom line and a more efficient operation overall.
