A rack that doesn’t align with the walking route. Stock management that is at odds with the physical layout. Internal transport that takes a ten-metre detour with every movement. In an ordinary warehouse, these are mere annoyances. In a sterile warehouse at a hospital or pharmaceutical company, they are risks that can have direct consequences for patients. That is precisely why the healthcare sector serves as an interesting mirror for any logistics manager who takes their warehouse seriously.
Storage, stock management and internal transport as a single system
In warehouses handling critical products, there is a strong temptation to tackle individual problems in isolation. A new shelf here, an extra scanning point there. But anyone analysing the storage space of a pharmaceutical company or hospital will quickly realise that this fragmented approach is counterproductive. A shelving unit that doesn’t align with the route taken by internal transport causes detours. Stock management that isn’t tailored to the physical layout of the warehouse leads to searching and errors during picking. The logistics manager who designs this system as a whole avoids these pitfalls.
That systems-based approach starts with the layout. Which products require separate storage? Which sizes dominate the product range? How often are pallets or bins moved, and by whom? Only once these questions have been answered does it make sense to look at racking types, walking routes and software support. Anyone who reverses that order ends up buying solutions for problems they have not yet properly defined.
Standardised sizes as the foundation of flexibility
One of the most practical lessons from warehouses with high standards of hygiene and traceability is the value of standardised sizes. In hospitals, the ISO size of 60×40 cm is standard for baskets and bins, not because it is mandatory, but because it keeps the layout manageable. If all products are stored in the same container sizes, the racking system fits in perfectly. New products slot straight in. And if the layout needs to be adjusted, only the positions need to change, not the system itself.
This principle applies to any warehouse with high standards of organisation and traceability. A warehouse manager in the food industry or at a technical wholesaler stands to benefit just as much from standardisation in sizes and storage racks. It reduces the complexity of layout, picking and replenishment, and makes adapting to a changing product range much easier.
Flexible racking: adapting without replacing everything
Warehouses are changing. New product lines, different delivery frequencies, a growing product range: the demands placed on storage space are constantly evolving. Fixed racking systems that cannot adapt are holding back this development. Flexible racking systems, where the height of the shelves and the width of the bays are adjustable, give the logistics manager the freedom to adapt the layout without major investment or structural alterations.
Suppliers of storage systems and stock management solutions therefore often work with modular ISO racking systems, which are available in powder-coated steel, aluminium or stainless steel, depending on the hygiene requirements of the environment. This makes the system adaptable without the need to change the racking beams. Even outside the healthcare sector, in distribution centres or in procurement departments managing seasonal product ranges, this adaptability is a competitive advantage. A warehouse layout designed to be modular and scalable ensures that organisational changes do not necessarily require a complete refurbishment.
Case study: reusing rather than replacing
Treant Zorggroep demonstrated how this works in practice. When the operating theatre centre at the Stadskanaal site relocated, the logistics flows changed and a new sterile warehouse was required. Instead of purchasing everything new, bespoke ISO partitions were fitted into standard ISO cabinets. This meant the existing stainless steel baskets could be reused. That is precisely the advantage of standardised sizes: once the carrier is fixed, the system around it can change without having to completely overhaul everything. The same approach was later applied at the Hoogeveen site. For warehouses outside the healthcare sector, the lesson is the same: those who opt for a standardised basis now will save themselves time and money later on.
Traceability requires a well-thought-out physical layout
Warehouses handling sterile or critical products have strict traceability requirements. The logic behind this is universal: if it is not clear where a product is located, when it arrived and when it is approaching its expiry date, the risk of errors increases. A warehouse management system helps, but only if the physical layout of the warehouse matches the way the system records locations. More and more warehouses are switching from scanning barcodes to reading RFID tags, so that location and stock levels are recorded without any additional steps.
In practice, this means: clear location labels, a logical routing sequence and a racking layout that supports FIFO or FEFO picking without requiring any extra effort from staff. In warehouses where this is well organised, stock-taking is quicker and picking errors are more easily prevented. The warehouse racking literally forms the backbone of the system: it determines which products are visible and accessible, and in what order they are picked.
Internal transport as an underestimated link
In many warehouse design projects, the movement of products through the warehouse receives less attention than the storage itself. Yet internal transport is the link that connects everything. In a hospital, an inefficient route between the receiving area, storage and the dispatch department results in time lost with every movement. Multiply that by hundreds of movements a day, and the impact on operational efficiency is significant.
Logistics managers outside the healthcare sector recognise this pattern. The solution does not always lie in more expensive equipment or additional staff, but in redesigning the route itself. By aligning the racking layout with the most frequent transport movements, by eliminating unnecessary crossings and by placing loading and unloading zones closer to the relevant storage locations, efficiency is improved, often without significant additional investment.
Warehouses with high standards of order, hygiene and traceability effectively act as a magnifying glass, highlighting problems that are latent in every warehouse. Anyone who takes the lessons from the healthcare sector seriously will discover that a well-thought-out combination of standardised sizes, flexible racking and a layout tailored to transport is not a luxury reserved for specialist environments. It is a solid foundation for any warehouse that wishes to continue operating efficiently, both now and in the face of change.
