  • Total anticipated volume of cargo for the specific storage location.
  • Numbers and types of independent types of goods (SKUs) needing to be accounted for.
  • Interior space adequate for the anticipated flow of work.
  • Need for handling equipment (MHE) for cargo items – MHE parking spaces, recharging, etc.
  • Duration stored goods will stay for / the duration the storage site may be required for.
  • Need for ancillary activities – repacking, labelling, kitting, break bulk, etc.
  • Speed at which throughput/ancillary activities may be required – multiple loading bays, large dispatch area, etc.
  • Need for special storage - cold chain, dangerous goods, etc.
  • Additional planned buffer stock required.

The individual volume needs of different organisations can vary. A generic list of volumes per common relief item can be found in the below table:

Actual items obtained from local or international sources may vary in volumes. Understanding the specific storage needs might involve obtaining the volumetric measurements and all special handling needs of all related relief items from either a supplier or a central distribution warehouse.

Irregular and Special Storage

As agencies attempt to plan out space need in storage locations, they may encounter bulky or irregular items. In addition to planning generic outside dimensions, space planners should also estimate the fully required volume to adequately store an item, not just the outside dimensions.

Irregular Shapes - Some irregular items, such as mechanical or farm equipment may have complex physical attributes that make space planning hard. When looking at highly irregular shapes, planners should consider the outside measurement of only the longest, widest and tallest parts of the item, as those are the parts that will come in contact with other stored items in a warehouse. To do this, planers should imagine an invisible box that is barely large enough to fit the irregular item, and use the “edges” of the “box” to calculate the total required space. In this way, the overall space requirement may actually be larger than they first appear.

Nested Cargo – Some cargo items can be neatly “nested,” meaning that they can rest inside of or occupy space inside of each other. Buckets – a common humanitarian item – can fit inside one another, taking up considerably less space when stored appropriately. When planning space, organisations should account for nested storage by measuring the outer dimensions of the items while stacked/nested, and not the outer dimensions of the individual unit. In this way, overall space requirement may actually be less than they first appear.

Physical Storage Space Aspects


After fumigation, continual inspection may be required. If infestations persist, there may be a need to alter storage or delivery methods. The use of additional liquid based pesticides may be required to spray around the exterior or floor of storage spaces. 

Physical Warehouse Maintenance Schedule 

Below is a suggested periodic maintenance schedule for warehouse management. 

  • Floors
  • Pest signs
  • Locks
  • Walls
  • Sides of racks, shelves, fridges
  • In-depth check for pest
  • Stability of racks, shelves
  • Exterior lighting systems
  • Perimeter walls/fences 
  • Floor
  • Stored Items
  • Roof
  • Gutter
  • Truck parking areas
  • Facility grounds
  • Wall cracks
  • Water leakages
  • Fire Extinguishers/Sand Buckets
  • Condition of handling equipment 

Warehouse Equipment Maintenance Schedule 

All equipment in warehouse facilities - including racking and shelving - will require periodic maintenance. This may include replacing parts, applying lubricants, checking batteries, conducting daily charging or cleaning, or just conducting ongoing inspection to ensure that service equipment and physical holding structures are not displaying signs of damage and distress. Generally, the service schedule for different equipment items will be provided by the manufacturer, however the overall need to conduct daily or weekly inspections may also depend on the size of the warehouse and the overall daily handling requirements. The larger the facility, the more pieces of equipment will likely require maintenance. Additionally, warehouses with high degrees of throughput may also require more regular maintenance. Warehouse managers should develop a maintenance schedule for warehouse equipment breaking down daily, weekly and monthly/yearly service needs, and should also maintain separate logbooks for key pieces of equipment, such as forklifts. Proper tracking of maintenance will increase the lifespan of expensive items, and will increase overall safety of the warehouse environment.
